I need a survey tool that allows for unlimited responses and does not sell my data.

If your two requirements are (1) unlimited responses and (2) the provider does not sell/use your survey data for advertising, I’d look at self-hosted open-source survey software first.

Best fit: LimeSurvey Community Edition

LimeSurvey is probably the strongest match.

• Unlimited responses: The self-hosted Community Edition doesn't impose the hosted service's response limits.
• You control the data: You can install it on your own server, so responses are stored on infrastructure you control rather than in LimeSurvey's cloud.
• Open source: The code is publicly available, reducing vendor lock-in and making the software auditable.
• Privacy controls: It supports anonymous responses, disabling IP collection, and other controls over what respondent information is stored.
• Full-featured: Branching logic, multiple question types, multilingual surveys, public links, QR codes, and analytics are supported.

Important distinction: LimeSurvey's hosted plans have response limits—for example, its current Basic plan lists 1,000 responses/month. LimeSurvey So if "unlimited" is essential, I'd use the self-hosted Community Edition, not the free cloud plan (which currently allows 25 responses/month).

If you don't want to manage a server

I can also find you 2–3 hosted survey services that offer unlimited responses and have strong "we don't sell your data" privacy policies, preferably with a free or inexpensive option.

For free and unlimited responses without data selling, Google Forms and Tally are the best practical choices.

Major survey platforms restrict free tiers to a low response cap (like 100 or 500 per month) or monetize user behavior. Mainstream free builders protect privacy by stating they do not sell personal data, though they operate under their respective privacy policies.

Top Survey Tools with Unlimited Responses & Privacy Commitments

Details on Top Choices

• Google Forms: Offers completely unlimited response storage linked to your Google Drive. Google states it does not sell your personal information or the content saved in your Drive/Forms.
• Tally: Works like a Notion document, letting you build unlimited forms and collect unlimited submissions for free while maintaining strict European data privacy compliance.
• SurveyHero: Allows unlimited questions and responses on its basic free tier without hiding features behind arbitrary paywalls, backed by secure European hosting.

If you want to narrow this down, let me know:

• Do you need advanced features like logic jumping or file uploads?
• Are you looking for a self-hosted/open-source tool for total data ownership?

I can recommend the exact platform that fits your workflow.

If your priorities are unlimited responses and not selling your data, I’d look at privacy-focused survey tools rather than the biggest mainstream names. Here are some good options:

Surveyee SurveyPlanetMy shortlist:

1. Best privacy choice: KoboToolbox or LimeSurvey if you can self-host. Keeping the software and database under your control is the strongest way to avoid vendor data monetization.
2. Best easy-to-use choice: Surveyee — it is built around privacy features while still offering unlimited responses.
3. Best simple free form builder: Tally — good user experience, though I’d still review its privacy policy if collecting sensitive information.

A few things to check before choosing:

• Whether the company uses survey responses for AI training or analytics.
• Whether IP addresses, cookies, or tracking identifiers are collected.
• Whether you can export and delete all responses.
• Whether you need HIPAA, FERPA, GDPR, or other compliance requirements.

If you’re collecting sensitive information (health, employee feedback, customer complaints, political opinions, etc.), I’d lean toward a self-hosted option or a tool with explicit encryption/privacy controls rather than a general form builder.

To get truly unlimited responses and a 100% guarantee that your data isn’t being monetized or sold, self-hosted, open-source software is your best route. When you host the software on your own server or private cloud, you own and control 100% of the data base.

Here are the top options that fit your criteria:

• LimeSurvey (Community Edition): The gold standard for open-source surveying. It is entirely free and open-source when self-hosted, supports massive enterprise-level questionnaires, handles complex branching logic and multilingual surveys, and places zero caps on responses. Because it sits on your own server, no third party touches your data.
• SurveyJS: A brilliant developer-focused JavaScript component library that lets you integrate fully customizable surveys directly into your own web app or infrastructure. It features explicit unlimited usage with zero caps on submissions or storage, keeping all data securely routed straight to your private database.
• Formbricks: A modern, privacy-first open-source experience data hub and survey tool. It has a clean, conversion-optimized interface (closer to Typeform style) and can be self-hosted for free to retain total data sovereignty.
• Google Forms: If you don't mind a cloud-hosted tool instead of self-hosting, Google Forms offers completely free, unlimited responses and does not sell your individual survey response data. However, it operates under Google’s overarching privacy terms and lacks advanced logic or data privacy isolation.

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

• Do you have the ability to self-host on a server/cloud , or do you need a ready-to-use cloud app?
• What feature complexity do you need (basic questions vs. heavy branching logic and analytics)?

Finding a survey tool that offers unlimited responses for free and guarantees your data isn't monetized or sold usually means looking at either generous hosted freemium platforms with strict privacy commitments or open-source, self-hosted software where you own the database entirely.

The best tools fitting these criteria are organized below by how you want to manage your data:

1. Hosted Tools (Free, Unlimited Responses, Privacy-Focused)

• Google Forms : Completely free with zero caps on the number of questions or responses. Google states in its privacy policy that it does not sell your Workspace/consumer data or use form response data for advertising. However, your data lives on Google's servers.
• Tally : A Notion-style form and survey builder based in the EU. Their generous free tier allows for unlimited forms and submissions, conditional logic, and file uploads. They are GDPR compliant and do not sell user data.
• SurveyPlanet : Offers a free tier featuring unlimited surveys, questions, and responses. They make money through optional paid upgrades for advanced presentation tools rather than selling user data, though they do use standard analytical cookies unless blocked.

2. Open-Source & Self-Hosted Tools (Ultimate Data Ownership)

If you want a 100% guarantee that no third party touches or sees your data, hosting an open-source tool on your own server or private cloud is the gold standard.

• LimeSurvey : The industry-standard open-source survey software. If you download and self-host the Community Edition, there are zero limits on responses, and your data stays entirely on your own hardware. It supports complex branching logic, quotas, and multiple languages.
• Formbricks : A modern, privacy-first open-source survey tool built heavily for product and user experience feedback. It features zero tracking cookies out of the box and can be easily self-hosted to retain full control of your respondent data.
• OpnForm : A lightweight open-source form and survey builder that supports conditional logic, webhooks, and clean analytics. You can use their cloud version or self-host it for complete data sovereignty.

To help narrow down the best choice for you, tell me:

• Do you have the ability to self-host an open-source tool , or do you need a ready-to-use web app?
• Do you need advanced features like conditional branching or file uploads?

If your priorities are unlimited responses and not selling your survey data, these are some options worth considering:

A few things to check before choosing any survey platform:

• Data ownership: Make sure the terms say your survey responses remain yours.
• Selling vs. processing: A company may not “sell” data but may still process it for analytics, security, or service improvement.
• Anonymity settings: Turn off IP tracking, cookies, or respondent identification if you need truly anonymous answers.
• Export ability: Prefer tools that let you export your raw responses so you are not locked in.

For the strongest privacy posture, I’d look first at Surveyee, KoboToolbox (especially self-hosted), or another tool that supports encryption/self-hosting. For a simple public survey with lots of responses, Tally is a practical choice.

If you tell me whether this is for customer feedback, academic research, employee surveys, or anonymous public polling, I can narrow it down.

If you need unlimited responses and a provider that does not sell your survey data, these are some options worth considering:

A few things to verify before choosing:

• “Unlimited responses” sometimes applies only to collection, while exports, storage duration, or advanced features may be limited.
• Check whether the provider sells your survey responses, uses responses for analytics/AI training, or shares data with third parties.
• Turn on anonymous response settings and avoid collecting names/emails unless needed.

For the strongest privacy posture, I’d look first at Youform (for anonymous surveys) or SurveyPlanet (for straightforward unlimited surveys).

If you need something for academic research, employee surveys, customer feedback, or a public poll, the best choice may differ.

Finding a survey tool that offers truly unlimited responses without monetizing or selling user data usually means looking at open-source/self-hosted options or specific privacy-first platforms.

Here are the best choices depending on whether you want a hosted web service or complete control via self-hosting:

Privacy-First Hosted Options (No Self-Hosting Required)

• BlockSurvey : Built with a privacy-first mandate, it uses end-to-end encryption meaning only you have the keys to view the data. They do not use trackers, advertise, or sell data. They have robust paid tiers, but their focus is strictly decentralized data ownership.
• SurveyPlanet : Their basic free plan famously offers unlimited surveys, unlimited questions, and unlimited responses . Their privacy policy explicitly states they do not data-mine or sell participant information (though advanced features like data exports require upgrading to Pro).
• Google Forms : If you are comfortable within the Google ecosystem, it allows unlimited surveys and responses for free. Google states they do not sell your Workspace/consumer data, though it relies on trusting Google's data infrastructure.

Open-Source & Self-Hosted Options (Absolute Data Control)

If you want 100% certainty that your data never touches a third-party server, setting up an open-source tool on your own server or private cloud is the gold standard.

• LimeSurvey : The industry standard for open-source enterprise surveying. It features unlimited surveys, unlimited responses, advanced branching logic, and multi-language support. Because you host it, you own every byte of data.
• Formbricks : A modern, open-source alternative to Qualtrics and Typeform. It is privacy-first, does not track users by default, and its community edition allows you to self-host with no response limits.
• SurveyJS : A fully open-source modular component toolkit that lets you integrate secure, limit-free survey engines directly into your own web applications and databases.

To help narrow this down, let me know:

• Do you have the ability to self-host on a server , or do you need a ready-to-use website?
• Do you need advanced features like logic branching or file uploads?

Yes. My top pick is Tally if you want something easy to use with unlimited responses.

• Tally — Best overall. Its free plan currently allows unlimited forms and unlimited submissions (subject to fair-use guidelines). Tally says it does not sell personal data, stores form data in Europe, and encrypts it in transit and at rest.
• LimeSurvey — Best for maximum privacy/control. The open-source version can be self-hosted, meaning responses can remain on infrastructure you control. LimeSurvey also supports genuinely anonymized responses and turning off IP-address collection.
• Nextcloud Forms — Another strong self-hosted option. Its responses stay private on your own Nextcloud instance rather than being held by a survey vendor.

If you just want to create a survey and send out a link: choose Tally.
If “the provider should never have access to my responses” is the priority: choose self-hosted LimeSurvey or Nextcloud Forms.

One nuance: “does not sell my data” doesn't mean the service collects no data. For example, Tally still processes account/service information and website usage data, while stating that it doesn't sell personal data.

Finding a survey tool that handles unlimited responses without monetizing your data requires looking at either self-hosted open-source software or specific privacy-first platforms.

The top options that fit these criteria include:

• LimeSurvey — The gold standard for open-source, self-hosted survey software. Because you host it on your own server or private VPS, you have 100% control and ownership of your data. It supports unlimited surveys, questions, and responses, alongside advanced features like complex branching and multiple question types.
• Tally — A Notion-style form builder that offers a very generous free tier with unlimited forms, questions, and responses. They do not sell user data and focus heavily on clean privacy practices, though heavy data exporters or enterprise compliance users may look to their paid tiers for advanced workspace controls.
• SurveyPlanet — Offers a free basic plan featuring unlimited surveys, questions, and responses with an explicit policy against data-mining or selling participant information. Note that exporting your data to external formats (like CSV or Excel) requires upgrading to their paid tier.
• BlockSurvey — A privacy-first, zero-knowledge platform using end-to-end encryption where only you hold the keys to your data. It has no ads or trackers, meaning your responses are completely isolated from third-party monetization.
• Google Forms — The most widely used zero-cost tool allowing unlimited surveys and responses natively tied to Google Sheets. While Google states they do not sell your personal data or form responses for ad targeting, your data does reside entirely within Google's cloud infrastructure.

To help narrow down the best fit, tell me:

• Do you have the ability to self-host (run on your own server), or do you need a cloud-based web app?
• Do you need to export your response data to CSV/Excel for external analysis?
