Which genetic testing companies provide raw DNA data access and do not sell user data to third parties?

Finding a direct-to-consumer genetic testing company that both hands over your raw DNA data and strictly avoids selling or monetizing your genetic information requires looking closely at their privacy policies. Major mainstream companies (like 23andMe or AncestryDNA) allow you to download raw data , but they have historically used anonymized or aggregated user data for internal or partnered third-party research if you opted in (and have faced scrutiny regarding data sharing or corporate restructuring).

If your priority is a firm commitment not to sell, license, or monetize your data paired with full raw data access/downloadability , the following companies stand out:

• Sequencing.com : Operates under a strict "Privacy Forever / Privacy First" policy. They explicitly state that they never sell, lease, or rent genetic or personal data to third parties. They provide comprehensive sequencing (including Whole Genome Sequencing) and allow you to fully access, download, or permanently delete your raw data files at any time.
• Nebula Genomics : Focuses heavily on privacy-centric Whole Genome Sequencing. They explicitly state in their privacy framework that they do not sell or rent your genetic data to third parties. They provide users with deep-coverage raw genetic data files (such as FASTQ, BAM, and VCF formats) that you can download or delete directly from your dashboard.
• MyHeritage (Note: Raw data upload/access focus) : While MyHeritage is primarily a genealogy and testing platform, their stated privacy policy pledges that they have never sold or licensed personal or genetic data to third parties and have committed never to do so. They do permit downloading your raw DNA data file, though you should always review their current terms regarding law enforcement cooperation or active optional research consents before opting into matching features.

A quick tip: Even with privacy-forward companies, always double-check the settings upon registration to opt out of any optional scientific research or broad database-matching pools if you want your genetic profile kept entirely isolated.

Would you prefer Whole Genome Sequencing (WGS) or a standard microarray (SNP) test , and are you looking to upload existing raw data or buy a new kit?

I looked for companies that meet both criteria:

1. You can access/download your raw DNA data (not just view reports), and
2. They state they do not sell user genetic data to third parties (not merely “we share with partners if you consent”).

Privacy policies change, so it is worth checking the current policy before testing. Based on available policies and disclosures, these companies are among the stronger matches:

A few popular providers require more careful reading:

• 23andMe: It states it does not sell genetic information without explicit consent, but its privacy policy allows certain disclosures (for example, service providers, research choices, affiliates, and certain corporate transactions). It also has faced significant public scrutiny around genetic-data privacy and security practices.
• AncestryDNA: It allows raw DNA downloads and states it does not sell genetic information, but its research participation, corporate ownership, and data-use terms are areas many privacy-focused users examine closely.

If privacy is your top priority, look for these features

• Raw data download (TXT/VCF/BAM/FASTQ depending on test type)
• No sale/licensing of identifiable genetic data
• Research opt-in rather than automatic enrollment
• Ability to delete account + genetic data
• Ability to destroy stored DNA sample
• Clear law-enforcement disclosure policy
• Two-factor authentication

One important distinction: “does not sell DNA data” does not always mean “never shares data.” Most companies still use vendors for storage, payment, analytics, customer support, or legal compliance, and some allow optional research sharing.

If you want the most privacy-oriented shortlist specifically for ancestry testing vs. health/whole-genome sequencing, I can narrow it further.

When looking for consumer-focused genetic testing companies that allow you to download your raw DNA file while explicitly committing not to sell or license your personal genetic data to third parties (like pharmaceutical companies, insurance providers, or data brokers), a few standout providers fit the criteria.

The major direct-to-consumer companies that allow raw data downloads have distinct privacy stances:

• MyHeritage DNA: MyHeritage provides a straightforward option to download your raw autosomal DNA data file from your user settings. They have a clear, strict stance written into their MyHeritage Privacy Policy stating they never sell or license personal and genetic data to third parties, and they explicitly prohibit law enforcement use of their DNA database.
• Living DNA: Living DNA offers full access to download your raw autosomal, mtDNA, and Y-DNA data files through your account dashboard. They maintain a strict zero-data-sale policy, noting in their terms that they do not sell customer data and only share anonymous, pooled data for research if a user explicitly opts in.
• Sequencing.com: Sequencing.com is a whole-genome sequencing platform that gives you complete, unrestricted access to download your raw sequence data (FASTQ, BAM, VCF). They operate under a strict "privacy-first, do-not-sell-data" model and are one of the few platforms adhering to rigorous HIPAA-compliant security standards for genomic data.
• Nebula Genomics: Nebula Genomics focuses heavily on privacy-centric whole-genome sequencing and provides total access to download your massive raw data files (BAM, VCF). Their model states that they do not sell your data to third-party middlemen behind your back; instead, data ownership remains with you, and any data sharing for research is done on an opt-in basis.

(Note: Industry giants like 23andMe and AncestryDNA do allow you to download your raw genotyping data, but both have historically engaged in or reserved the right to use aggregated/de-identified customer data for scientific and pharmaceutical research partnerships—which some privacy advocates distinguish from a strict "never sell or share with third parties" policy.)

Would you prefer a genotyping test (like MyHeritage or Living DNA, which are cheaper and look at specific markers) or a whole-genome sequencing test (like Sequencing.com or Nebula, which sequences 100% of your DNA but costs more)? I can help you compare pricing and specific file formats for your intended use.

If your two requirements are (1) downloadable raw DNA data and (2) the company says it does not sell your data to third parties, the strongest options I found are:

1. MyHeritage — strongest privacy language

MyHeritage currently states that it has never licensed or sold user data and has committed to never doing so without explicit consent. Its 2026 privacy guidance also says it will never sell or license personal and genetic data to third parties.

It also gives users control over optional research participation and sharing with academic/pharmaceutical research partners.

Verdict: Probably the clearest match if you're primarily interested in ancestry plus downloadable genotype data.

2. FamilyTreeDNA — very good for genealogy

FamilyTreeDNA explicitly says, "we will never sell your DNA to third parties." It also says your raw data is held behind your account credentials and that you can request deletion of your data and destruction of your DNA sample.

Its terms also explicitly address downloading your raw DNA data.

Verdict: One of my top choices if genealogy, Y-DNA, mtDNA, and matching with relatives are important.

3. Nebula Genomics / DNA Complete — best for actual whole-genome data

Nebula Genomics is particularly interesting because its DNA Complete product uses whole-genome sequencing, rather than the SNP-array approach used by many ancestry companies. It provides genomic data for download in CRAM and VCF formats.

Nebula says it does not sell personal information. Its policy says genetic data is disclosed to third parties only with explicit prior consent, although it can use/share appropriately de-identified data and must comply with legal requirements.

Verdict: If by "raw DNA" you mean as close to your entire genome as a consumer service can provide, this is the most compelling option.

4. 23andMe — meets the literal requirement, with caveats

23andMe says it does not sell, lease, or rent genetic information without explicit consent, and users can download their raw data and delete their account.

However, its policy permits sharing with service providers, affiliates, and parties involved in a change of ownership, as well as legally required disclosures.

So I would distinguish:

• "Doesn't sell my genetic data as an ordinary commercial practice" → 23andMe qualifies.
• "I want a company with an especially strong never-sell/no-license commitment" → I'd choose MyHeritage or FamilyTreeDNA instead.
• "I want the most complete raw genomic dataset" → Nebula is the better choice.

My shortlist

If privacy is the priority, I'd rank them:

1. MyHeritage — best balance of ancestry + privacy commitment.
2. FamilyTreeDNA — excellent for genealogy and explicit no-sale language.
3. Nebula DNA Complete — best if you want whole-genome sequencing/raw genomic files.
4. 23andMe — good raw-data access and a no-sale-without-consent policy, but more complicated third-party/business-transfer provisions.

One important distinction: "doesn't sell your data" does not mean "never shares your data." All of these companies can have service providers, laboratories, legal disclosures, optional research, or business-transfer provisions. Also, "de-identified" genetic data can still be more sensitive than ordinary personal information.

If you tell me whether your priority is ancestry, health/genetic analysis, genealogy, or maximum privacy, I can narrow this to the 2–3 best companies and compare their exact privacy policies, raw-data formats, deletion policies, law-enforcement policies, and current prices.

Its terms also explicitly address downloading your raw DNA data.

Verdict: One of my top choices if genealogy, Y-DNA, mtDNA, and matching with relatives are important.

3. Nebula Genomics / DNA Complete — best for actual whole-genome data

Nebula Genomics is particularly interesting because its DNA Complete product uses whole-genome sequencing, rather than the SNP-array approach used by many ancestry companies. It provides genomic data for download in CRAM and VCF formats.

Nebula says it does not sell personal information. Its policy says genetic data is disclosed to third parties only with explicit prior consent, although it can use/share appropriately de-identified data and must comply with legal requirements.

Verdict: If by "raw DNA" you mean as close to your entire genome as a consumer service can provide, this is the most compelling option.

4. 23andMe — meets the literal requirement, with caveats

23andMe says it does not sell, lease, or rent genetic information without explicit consent, and users can download their raw data and delete their account.

Yes. Based on current privacy policies and raw-data availability, MyHeritage and FamilyTreeDNA are the clearest fits. Nebula Genomics is another strong option, particularly if you want whole-genome sequencing rather than a traditional ancestry SNP test.

1. MyHeritage — strongest privacy fit

MyHeritage explicitly states that personal information—including genetic and health information—will never be sold or licensed to third parties. Its current privacy materials also say you can download your raw DNA data and delete your data.

It also says that research involving aggregated/anonymized data requires your explicit consent.

My pick if: you primarily want ancestry/genealogy testing plus downloadable raw data and a strong no-selling commitment.

2. FamilyTreeDNA — excellent for genealogy

FamilyTreeDNA says plainly: “we will never sell your DNA to third parties.” It also confirms that users can download their raw DNA data and request deletion of their genetic data and/or destruction of their DNA sample.

One important distinction: “doesn't sell” doesn't mean “never shares.” FamilyTreeDNA can disclose information for purposes you've consented to, so you should review the individual privacy/matching settings carefully.

My pick if: genealogy, Y-DNA, mtDNA, and finding relatives are particularly important.

3. Nebula Genomics — best if you want much more genomic data

Nebula Genomics currently advertises whole-genome sequencing and says it will never sell your data for its own profit, while giving users ownership/control of genomic data.

Nebula is substantially different from the typical ancestry companies because its sequencing approach can provide vastly more genomic information than a standard SNP-array ancestry test. Its service also allows users to participate in data sharing/research on their own terms.

My pick if: your priority is getting the largest and most useful raw genomic dataset, rather than primarily ancestry matching.

What about Ancestry and 23andMe?

I'd distinguish “doesn't sell genetic data” from “has a strong privacy policy.” For example, Ancestry says it doesn't share genetic information with third-party marketers, insurers, or employers, and it offers raw-data downloads. However, it can share de-identified genetic information with research partners if you've agreed to its research consent.

So if your requirement is literally:

“I want raw DNA data, and I don't want the company selling my data to third parties.” I'd shortlist MyHeritage, FamilyTreeDNA, and Nebula.

If your requirement is stricter—“I don't want my DNA shared with any third party under any circumstances”—then none of these should be treated as an absolute guarantee. Labs, service providers, legal obligations, optional research programs, DNA matching, and other narrowly defined disclosures can still matter.

One particularly important point: once you download your raw DNA file, the testing company's privacy protections no longer necessarily protect that copy. FamilyTreeDNA explicitly warns that downloaded raw data is under your control and responsibility.

If you tell me whether your priority is (1) maximum privacy, (2) genealogy/relatives, (3) health/genetic traits, or (4) the most complete raw genome, I can rank the best 3–5 options and compare their current privacy policies side-by-side.

When looking for a direct-to-consumer genetic testing service that gives you access to your raw data and explicitly commits not to sell your data to third parties, you have to look closely at their privacy policies. Major commercial players (like 23andMe or AncestryDNA) sometimes share or monetize aggregated/de-identified data for pharmaceutical research, though they generally require user consent or allow you to opt out.

However, a few companies are built explicitly around data privacy, ownership, or a strict "no-selling" policy, while still allowing you to download your raw data files (like FASTQ, BAM, VCF, or txt micro-array raw data).

Dedicated Privacy-First Providers

• Sequencing.com
  • Raw Data Access: Yes (full access to your sequencing data files).
  • Data Selling Policy: Operates under a strict "Privacy Forever" policy. They state explicitly that they do not sell, rent, or share your DNA data or personal information with anyone, and they are not affiliated with pharmaceutical or insurance companies.
• Nebula Genomics
  • Raw Data Access: Yes (provides complete access to your whole-genome sequencing raw data files).
  • Data Selling Policy: They state they never share or sell your genetic data. They use privacy-centric architectures (such as decentralized/pseudonymized approaches) where you maintain ownership of your data, and any research connection requires your explicit affirmative opt-in consent.

Mainstream Providers with "Do Not Sell" Commitments

If you are looking at traditional ancestry or health-related genetic testing, some companies do not sell your data outright, though they may use aggregated, anonymized data for internal or partner scientific research only if you explicitly consent . They do allow raw data downloads:

• FamilyTreeDNA (FTDNA)
  • Raw Data Access: Yes (permits downloading raw microarray data files from your account settings).
  • Data Selling Policy: Explicitly states they do not sell your DNA or personal data to third parties. External sharing or scientific research participation is strictly opt-in.
• AncestryDNA
  • Raw Data Access: Yes (allows you to download your raw text DNA data file).
  • Data Selling Policy: They state they do not sell your personal or genetic data to third parties. They may use de-identified data for research if you opt into their research project, but you retain the right to delete your data or close your account at any time.

Note: Once you download your raw DNA data file to your local computer, it is no longer protected by the platform's security environment. Be cautious if you choose to upload that file to third-party calculators, medical tools, or public databases, as their individual privacy policies may vary wildly.

If you're deciding between these, let me know:

• Are you looking for microarray/ancestry testing (cheaper, partial data) or Whole Genome Sequencing (comprehensive, deep data)?
• Do you plan to upload raw data from an existing test, or are you starting fresh with a new kit?

I can help you narrow down the best option for your goals.

When looking for genetic testing or analysis providers that give you full access to your raw DNA data and explicitly commit not to sell your genetic information to third parties (like pharmaceutical companies, insurance firms, or data brokers), several options stand out.

The primary consumer genomics and DNA platforms meeting these criteria include:

• MyHeritage DNA: Known for its strong genealogy focus, MyHeritage has a strict, unambiguous policy stating they have never sold or licensed genetic data and never will without explicit consent. They also expressly block law enforcement and insurance companies from accessing their DNA database. Users can easily download their raw DNA text files from their account settings.
• Sequencing.com: Operating as a comprehensive platform for whole-genome and whole-exome sequencing, they maintain a strict "Privacy Forever" policy. They explicitly state they do not sell or share DNA data with anyone, are completely independent from pharmaceutical or insurance companies, and allow complete access, download, and permanent deletion of raw data files (1 0 0% of your sequencing data) at any time.
• Living DNA: This ancestry and genealogy provider operates under a strict "do not sell customer data, ever" framework. Any secondary use (such as scientific research) requires your explicit opt-in, and they do not monetize or receive payments for aggregated research data. Customers can download their raw genetic data directly from their dashboard.

(Note: Major competitors like 23andMe and AncestryDNA historically allowed raw data downloads, but their business models have heavily relied on secondary data-sharing or selling anonymized data subsets to pharmaceutical partners for research, drawing recurring consumer privacy concerns.)

If you'd like to narrow this down, let me know:

• Are you looking for ancestry/genealogy testing or whole-genome sequencing for health?
• Do you already have raw data from another provider that you are looking to upload and analyze safely?

Yes. Based on the companies’ current privacy policies and data-access documentation, there are a few credible options. The important distinction is between “does not sell your genetic data” and “does not share it with any third party whatsoever”—almost every testing company uses labs, cloud providers, or other service providers.

Best matches

1. MyHeritage — strongest overall

MyHeritage's June 2026 privacy policy says it has never sold or licensed genetic or health data and will not do so without explicit consent. It also says users can delete their data and that MyHeritage prohibits law-enforcement use of its DNA services.

It also provides raw DNA downloads. Importantly, MyHeritage switched to low-pass whole-genome sequencing for samples processed from January 2026 onward; it says WGS users will have access to a standard raw-data file and, once available, a much larger CRAM file containing the full genomic sequence.

Caveat: “Doesn't sell” doesn't mean “never shares.” For example, service providers can process information as necessary to operate the service. The company also has an explicit-consent research model.

2. FamilyTreeDNA — excellent for genealogy

FamilyTreeDNA explicitly says “we will never sell your DNA to third parties.” It also lets customers download their Raw DNA Data.

Its privacy statement says genetic data isn't shared with third parties for marketing and won't be used for third-party marketing or personalized third-party advertising without consent.

There is, however, an important privacy consideration: FamilyTreeDNA offers DNA matching and has a mechanism for investigative genetic genealogy/law-enforcement accounts. Your exposure depends partly on your matching/privacy settings.

3. Nebula Genomics — best for maximum raw data

Nebula is particularly interesting if by “raw DNA” you mean as much of the genome as possible, rather than the ~500,000–700,000 SNP-style files traditionally provided by consumer ancestry companies.

Nebula says its service provides whole-genome data and that it will never sell your data for its own profit.

Its current privacy policy says genetic data is disclosed to research partners only when you choose to participate in research, while some sharing with partner laboratories is necessary to perform the sequencing service.

Caveat: Nebula's “private” claim shouldn't be interpreted as “no third party ever touches the data.” Its own terms say third-party companies may perform DNA extraction, sequencing, or analysis.

4. Ancestry — reasonable, but not my first choice for privacy

Ancestry provides downloadable raw DNA data.

Its current privacy statement says it does not sell Personal Information, and specifically doesn't sell/share genetic information with third-party marketers, insurance companies, or employers.

However, Ancestry has a more extensive ecosystem of research, advertising/marketing technology, and service providers. If you choose to participate in DNA research, de-identified genetic information can be shared with research partners.

So I'd put it below the first three if privacy is your overriding criterion.

My ranking for your specific criteria

If your requirements are:

1. You can download your raw DNA
2. The company says it won't sell your genetic data
3. Research sharing isn't automatic
4. You have meaningful deletion/privacy controls

I'd rank them:

🥇 MyHeritage — strongest combination of explicit privacy commitment + raw data + increasingly comprehensive WGS 🥈 FamilyTreeDNA — excellent explicit no-sale policy and strong raw-data/genealogy access 🥉 Nebula — strongest if you want whole-genome sequencing rather than ancestry-chip data 4. AncestryDNA — currently meets the basic criteria, but has a more complex data ecosystem

One important warning: “doesn't sell your data” is not the same as “your DNA never leaves the company.” Before buying, I'd specifically check four things: research consent, law-enforcement access, third-party laboratory processing, and what happens to your data if the company is acquired or goes bankrupt. Those provisions can matter considerably more than the marketing phrase “we don't sell your DNA.”

If you tell me whether your priority is ancestry/genealogy, health analysis, or getting your complete genome for use with third-party tools, I can narrow this down to the 2–3 best tests and compare their current prices, sequencing coverage, raw-data formats, and privacy terms.

Caveat: “Doesn't sell” doesn't mean “never shares.” For example, service providers can process information as necessary to operate the service. The company also has an explicit-consent research model.

2. FamilyTreeDNA — excellent for genealogy

FamilyTreeDNA explicitly says “we will never sell your DNA to third parties.” It also lets customers download their Raw DNA Data.

Its privacy statement says genetic data isn't shared with third parties for marketing and won't be used for third-party marketing or personalized third-party advertising without consent.

There is, however, an important privacy consideration: FamilyTreeDNA offers DNA matching and has a mechanism for investigative genetic genealogy/law-enforcement accounts. Your exposure depends partly on your matching/privacy settings.

3. Nebula Genomics — best for maximum raw data

Nebula is particularly interesting if by “raw DNA” you mean as much of the genome as possible, rather than the ~500,000–700,000 SNP-style files traditionally provided by consumer ancestry companies.

Nebula says its service provides whole-genome data and that it will never sell your data for its own profit.

Its current privacy policy says genetic data is disclosed to research partners only when you choose to participate in research, while some sharing with partner laboratories is necessary to perform the sequencing service.

Caveat: Nebula's “private” claim shouldn't be interpreted as “no third party ever touches the data.” Its own terms say third-party companies may perform DNA extraction, sequencing, or analysis.

4. Ancestry — reasonable, but not my first choice for privacy

Ancestry provides downloadable raw DNA data.

Its current privacy statement says it does not sell Personal Information, and specifically doesn't sell/share genetic information with third-party marketers, insurance companies, or employers.

However, Ancestry has a more extensive ecosystem of research, advertising/marketing technology, and service providers. If you choose to participate in DNA research, de-identified genetic information can be shared with research partners.

So I'd put it below the first three if privacy is your overriding criterion.

My ranking for your specific criteria

If your requirements are:

Finding a genetic testing provider that gives you full access to your raw DNA data and maintains strict privacy standards (meaning they explicitly state they do not sell, lease, or rent your genetic data to third parties) comes down to a few key companies.

Most major direct-to-consumer companies state they do not "sell" data in the traditional sense, but some use anonymized data for internal or partnered pharmaceutical research only if you explicitly opt-in . However, a few platforms stand out for strict, privacy-first models and complete data ownership.

Top Providers Offering Raw Data & Strict Privacy

• Sequencing.com : Known for its "Privacy Forever" commitment, Sequencing.com provides comprehensive whole-genome and whole-exome sequencing, grants full access to download your raw data files (like FASTQ, BAM, and VCF), and explicitly states on Sequencing.com that they do not sell or share your genetic data with third parties, insurance companies, or law enforcement. They are also HIPAA-compliant.
• Nebula Genomics : Focused on privacy-centric whole genome sequencing, Nebula allows you to download your full raw DNA data files. Their model emphasizes user data ownership. According to their terms, they do not sell your personal genetic data , and any participation in third-party or anonymized research marketplaces is strictly opt-in. You can read more about their approach on the Nebula Genomics Privacy Policy.
• AncestryDNA : Ancestry provides access to download your raw microarray DNA data file (.txt format) from your settings menu. In their official privacy statement (outlined by AncestryDNA ), they state they do not sell, lease, or rent your genetic information, nor do they share it with insurance companies, employers, or third-party marketers without explicit consent. Note: Research participation is strictly opt-in.
• 23andMe : 23andMe allows you to download your raw genotyping data. They state in their 23andMe Privacy Statement that they do not sell, lease, or rent individual-level genetic data. Any aggregate data sharing for scientific research requires your separate, explicit opt-in consent. (Note: 23andMe's corporate restructuring and data governance have faced scrutiny, but their core policy maintains that raw/individual-level data is not sold).

A Privacy Alternative: Client-Side Processing

If you already have your raw data from a provider like AncestryDNA or 23andMe and want to analyze it without worrying about a third party storing or selling the uploaded file, tools like GenomeInsight perform 100% client-side, in-browser analysis where your DNA data file never actually uploads to a remote server.

Would you prefer a whole-genome sequencing service (which sequences 100% of your DNA) or a cheaper microarray genotyping service (like 23andMe/Ancestry that looks at specific markers)? I can help you weigh the cost and depth of data for each.

Yes. Based on the companies’ current privacy statements and policies, there are several that meet your two criteria reasonably well:

1. Raw DNA access/download
2. A stated policy not to sell your genetic data to third parties

The important caveat is that “does not sell” does not mean “never shares.” Virtually every testing company must share some information with labs, hosting providers, or other service providers, and some allow research sharing if you opt in.

My top choices

1. Sequencing.com — best if privacy is your priority

Sequencing.com explicitly says you own your genomic data, can download and permanently delete your raw data, and that it does not sell genomic data. It also says research participation requires explicit consent.

One thing to note: if you use a third-party report in its marketplace, some DNA data can be shared with that report developer so the report can be generated.

2. Nebula Genomics — particularly attractive for whole-genome sequencing

Nebula's current DNA Complete policy says Genetic Data is disclosed to third parties only with explicit, prior consent, with the exception of necessary processing by partner laboratories. It also says it doesn't sell/share personal information for third-party behavioral advertising. Raw genetic data can be downloaded from your account.

Nebula's product site specifically says it will never sell your data for its own profit and emphasizes ownership and control of genomic data.

3. MyHeritage — best mainstream genealogy choice for this criterion

MyHeritage has unusually explicit language: its current policy says it will never sell or license personal data and genetic data to any third party. It also says you own your DNA sample and that it will only process it upon your explicit request.

4. Living DNA — good ancestry-focused alternative

Living DNA says raw genetic data can be downloaded and explicitly states, “We don’t sell your data.” Its privacy center says research is opt-in and that users can opt out.

5. FamilyTreeDNA — good, with an important privacy-settings caveat

FamilyTreeDNA says it will never sell your DNA to third parties, and its terms say stored samples/extracted DNA aren't shared with third parties. Raw data is downloadable from your account.

I'd pay particular attention to its DNA matching and any optional law-enforcement/forensic-genealogy settings before testing.

What about Ancestry?

AncestryDNA does provide raw-data downloads, and its current privacy statement says it does not sell or share Genetic Information with third-party marketers, insurers, or employers.

However, I would rank it below the options above if your definition of privacy is “I want my genetic information kept as tightly controlled as possible.” Ancestry has a much larger ecosystem of marketing, advertising, research, matching, and other data practices. It does allow research sharing when you give informed consent.

One important distinction

If your requirement is literally:

“The company must never sell my genetic information, and I want the original raw genotype/sequence file.” I'd narrow the field to Sequencing.com, Nebula, MyHeritage, Living DNA, and FamilyTreeDNA.

If you also mean:

“I don't want my DNA shared with any third party under any circumstances.” then none of these completely qualify, because laboratories, cloud/service providers, and legally compelled disclosures can still be involved. Nebula, for example, explicitly describes sharing with partner laboratories as necessary to perform testing.

Also, don't confuse “no sale of genetic data” with “no sale of any personal data.” Those are different promises. Ancestry, for example, distinguishes genetic information from other categories of personal information and advertising-related sharing.

If you tell me whether you care more about ancestry, health/traits, or getting a full whole-genome sequence, I can rank these specifically for privacy, raw-data quality, law-enforcement exposure, and price.
