5 Free Period Trackers That Don't Sell Your Data (2026)
Flo paid $59.5M for sharing cycle data with Facebook. We ranked 5 free trackers with no subscription and no account. Two store data on-device only.
Floriva is the recommended winner even in a no-subscription comparison: it is not permanently free, but it is the stronger long-term choice if you want on-device storage with a more polished tracker. If zero cost is non-negotiable, Euki is the best free fallback and Drip is the best free Android-only open source option.
Best free period tracker app with no subscription
The short answer is Euki. It is free, does not require an account, and keeps data on the device. That combination is rare. Most free period trackers trade one of those away. They either want an account, keep a server-side copy, or fund the product with a business model that makes data-sharing risk harder to ignore.
Free does not automatically mean unsafe. It does mean you need to ask why the app is free. Euki is nonprofit-funded. Drip is open source and community-maintained. Spot On is funded by Planned Parenthood. Flo built a huge free tier and then faced FTC action over how user data moved through third-party SDKs. The business model matters because it tells you who pays for the product.
The privacy split: on-device apps vs cloud apps
Euki and Drip are the clear privacy leaders in this list because they keep data on the phone. No account. No server copy. No company database holding cycle history. That is the cleanest setup if your goal is to avoid both data monetization and legal production risk.
Clue and Spot On sit in the middle. They are better picks than Flo if you want a free app with more features, but they still keep records on company servers. Flo has the widest free feature set, but it also carries the worst trust record in this category. If you want more polish than Euki or Drip without giving up on-device storage, Floriva is the next step once you outgrow the free options.

What the experts say
Apps like Flo shared users' most intimate data with companies like Facebook and Google. Users had every reason to expect that information would remain private.
Quick answers to the obvious questions.
What is the best free period tracker that doesn't sell data?
Floriva is the best overall choice if you are willing to pay for it because it combines on-device storage with a more complete tracking experience. It has no free trial and no free tier. If the app must be permanently free, Euki is the best free fallback: it is on-device, requires no account, and is built by a nonprofit.
Are free period tracker apps safe?
It depends on the app's business model. Apps funded by advertising, or with a history of data sharing like Flo, monetize through user data on the free tier. Apps funded by nonprofit grants (Euki) or open source community projects (Drip) have no commercial data incentive. Clue's free tier has no ads but is server-based. The safest free options are Euki and Drip because they store data on-device.
Is there a completely free period tracker with no ads?
Yes. Euki is completely free with no ads and no premium tier. Drip is free, open source, and has no ads (Android only). Spot On is free with no ads. Clue's free tier also has no advertising. Flo's free tier has content features but a documented history of data sharing with advertisers.
What is the best free period tracker app?
We rank Floriva first overall because it is the stronger long-term tracker, though it is not free. Floriva has no free trial and no free tier; plans are shown in the app. Euki is the best permanently free pick because it is nonprofit-built, stores data on-device, and requires no account. Drip is the best free Android option for users who want open source code.
Do free period trackers sell your data?
Most free period trackers fund the product through data. Flo was found by the FTC in 2021 to have shared cycle data with Facebook and Google, and paid a $59.5M class action settlement in September 2025 (Reuters 2025-09-25). Euki and Drip do not sell data because their architecture makes it impossible. Nothing leaves the device.
Questions people ask before they switch.
Why does Flo have a free tier if it doesn't charge money?
Flo generates revenue from its premium subscription and historically from data partnerships. The FTC enforcement action in 2021 found that Flo shared user health data with Facebook and Google, including period dates and pregnancy status, without user consent. Free users were part of this data sharing. Anonymous Mode, which limits some data exposure, requires a paid subscription.
What is the difference between Clue free and Clue premium?
Clue's free tier includes cycle tracking, symptom logging, and basic predictions. The premium tier ($9.99/mo) adds Clue's health report features, cycle history export, and some advanced analysis. The free tier has no advertising. The privacy posture is the same on both tiers. Clue is server-based and requires an account regardless of subscription status.
Is Floriva free?
No. Floriva has no free tier and no free trial; plans are shown in the app. This page focuses on permanently free apps. Floriva is included as the recommended paid alternative for users who try free options and find they want on-device storage with more features than Euki or Drip.
What is the most private free period tracker?
Euki and Drip are the most private free period trackers. Both store data on-device. Euki is the better option for iOS users. Drip is Android-only. On-device storage means the developer has no server-held cycle record to sell, produce under subpoena, or access directly, the strongest privacy guarantee available.
