Yes. Based on the current terms I found, Tally is probably the best fit if you want something simple and free.

|---|---|---|---|
| Tally | ✅ Yes, free, subject to fair-use | ⭐ Strong privacy positioning; GDPR-compliant | Best overall |

I'm looking for a private survey builder that supports unlimited submissions without selling user information.
| ⚠️ Hosted free plan has limits; self-hosting can remove vendor limits |
| ⭐⭐⭐ Excellent control; open-source |
| Best for maximum privacy/control |
| Google Forms | ❌ Not unlimited anymore | ⚠️ Google ecosystem/data practices make it less ideal for your requirement | Not my first choice |
Tally explicitly advertises unlimited forms, questions, and responses for free, subject to fair-use guidelines. It also describes itself as GDPR-compliant and privacy-focused.
One caveat: “does not sell my data” is a stronger claim than “GDPR-compliant” or “privacy-friendly.” I would check Tally's current privacy policy before collecting sensitive information. If you want, I can specifically verify whether Tally's privacy policy says they sell/share survey responses or personal data, rather than relying on their marketing language.
If privacy is your top priority, I'd seriously consider LimeSurvey—especially its self-hosted/open-source version. It supports anonymized responses where even an administrator cannot link responses back to participants, and it provides detailed controls for encryption and personal data.
The hosted free plan isn't unlimited on responses, though, while the paid hosted plans have response caps as well.
Bottom line: For a normal survey, I'd pick Tally. For a survey involving sensitive information where you want the strongest possible control over the data, I'd pick self-hosted LimeSurvey.
Finding a survey tool with unlimited responses that guarantees your data won’t be monetized or sold usually points you toward two solid routes: fully free cloud-hosted tools with privacy-first business models, or open-source, self-hosted software where you own 1 0 0% of the infrastructure and data.
Here are the best options matching your criteria:
To help narrow down the best fit, tell me:
LimeSurvey (Self-Hosted) is the best choice for unlimited response capacity combined with an absolute guarantee that your data will never be sold.
When you host an open-source platform on your own server, you retain total ownership, control, and physical jurisdiction over your data. Commercial Software-as-a-Service (SaaS) platforms—even paid ones—often have complex terms of service regarding analytics, telemetry, or third-party cloud sub-processors.
| Platform | Response Capacity | Data Ownership & Privacy Guarantee | Best Use Case |
|---|---|---|---|
| LimeSurvey (Self-Hosted) | Unlimited (limited only by your server storage/bandwidth) | Complete ownership. Data resides on your hardware; third parties never touch it. | Secure, confidential, and high-volume research. |
| Google Forms | Unlimited (free personal accounts) | Google Privacy Policy. Google does not sell your personal data or survey results, but uses data under its privacy terms for service operation and ad profiling ecosystems. | Quick, casual, or non-sensitive data collection. |
| Tally | Generous free/unlimited tier for core form building | GDPR compliant. Privacy-focused, though hosted on their cloud infrastructure. | Modern, notion-style clean surveys. |

If your two main requirements are unlimited survey responses and a commitment not to sell your data, I’d prioritize platforms that explicitly address both in their official terms and privacy policies—not just platforms that advertise themselves as secure.
One important distinction: a company may promise not to sell your data while still using service providers to process it or sharing certain information for advertising. Also, “unlimited responses” can mean unlimited collection, unlimited access to results, or both.
(Best free option)
SurveyPlanet explicitly offers unlimited surveys, questions, and responses on its free plan. It also advertises anonymous surveys, SSL security, and no data mining or information selling.
Best for: Personal research, students, nonprofits, and anyone who wants to collect lots of responses without paying per response.
Trade-off: Exporting results to CSV and other advanced features require Pro. Review the full privacy policy to understand what information beyond your survey responses is collected.
(Best for larger research projects)
Zoho makes an explicit company-wide commitment that it does not sell user information for advertising. Its survey pricing lists plans with unlimited annual responses, although limits can apply to monthly plans.
Best for: Organizations that need more survey logic, reporting, integrations, and data management.
Trade-off: Check the exact plan's response limits, billing cycle, and current price before subscribing.
SurveyMonkey explicitly says it does not sell customers' or respondents' data and offers substantial security and compliance controls. However, standard plans have response limits or additional-response charges, so unlimited capacity must be negotiated or confirmed for your specific plan.
Best for: Professional research teams that need mature analytics, collaboration, and security controls.
I'd start with SurveyPlanet if you want unlimited responses at no cost and a clear no-selling claim. If you need more advanced reporting or organizational features, investigate Zoho Survey next.
Before uploading sensitive or confidential information, verify that the provider's privacy policy covers survey responses, respondent identifiers, and any use of third-party service providers. No platform can guarantee absolute privacy in every circumstance.
One question that would help me narrow this down: Do you need the platform to be completely free, or are you willing to pay for unlimited responses?
