Best Period Tracker After the Flo Settlement: 4 Alternatives Compared
After Flo's $59.5M class action settlement, here are the best period tracker alternatives compared. Floriva, Euki, Drip, and Clue evaluated on privacy, features, and data architecture.
Flo shared user health data with Facebook and Google, leading to a $59.5M combined settlement in 2025. If you're leaving Flo, the strongest privacy options are on-device trackers: Floriva (iOS + Android, paid app with no free tier, encrypted sync), Euki (free, decoy screen), and Drip (free, open-source, Android-only). Clue is a cloud-based alternative with GDPR protection but still stores data on servers.
Flo shared your period data with Facebook and Google. The FTC confirmed it in 2021. A $59.5M combined settlement resolved the class action in September 2025. If you're reading this, you're probably deciding what to use instead.
Here are four alternatives evaluated on the only question that matters: what happens to your data.
Why Users Are Leaving Flo
The FTC found that Flo shared sensitive health data (period dates, pregnancy status, symptom information) with Facebook, Google, and third-party analytics firms through embedded SDKs. Users who logged their most intimate health data did so believing it was private. It wasn't.
Flo launched Anonymous Mode in response, but it requires a premium subscription. Privacy as an upsell, after the company was caught violating it for free-tier users. The architecture remains cloud-based. Your data still lives on Flo's servers.
For a full breakdown, see Flo app alternative and the Flo vs Floriva data comparison.
Option 1: Floriva. On-Device with Sync
Floriva keeps core data on your device. No account is needed for core tracking. No analytics SDKs track cycle data. Cross-device sync works through end-to-end encryption. Only encrypted data moves through the sync service.
Why choose Floriva: iOS and Android with encrypted sync solves the main problem with on-device trackers: data loss when you change phones. No account required. You can start tracking without an email address.
The tradeoff: Paid app with no free tier. Closed source. Newer app with a smaller prediction dataset than Flo's.
Floriva is a zero-knowledge tracker. The company cannot read your cycle data because core records stay on your device and synced records are encrypted before they leave it.
Option 2: Euki. Free On-Device Tracking
Euki is backed by the International Planned Parenthood Federation. Free. On-device storage. No account. Includes a decoy screen that shows fake content if someone opens your app, useful for physical device privacy that software architecture alone doesn't address.
Why choose Euki: Free, on-device, and includes broader sexual health resources beyond cycle tracking. The decoy screen is unique among period trackers.
The tradeoff: No sync. Lose your phone, lose your data. Development updates are less frequent than commercial apps.
Option 3: Drip. Open-Source Verification
Drip is free, open-source, and Android-only. The source code is on GitHub under GPLv3. You don't need to trust anyone's privacy claims, you can read the code and verify that the app doesn't send data anywhere.
Why choose Drip: The source code is public. You can verify the privacy claims yourself rather than trusting a policy statement.
The tradeoff: Android only. No iOS version. Minimal UI. Small volunteer development team. Functional but not polished.
Option 4: Clue. Cloud with GDPR
Clue is the strongest privacy option among cloud-based trackers. German-incorporated, GDPR-regulated, with public commitments to resist law enforcement requests for reproductive health data. No FTC enforcement history.
Why choose Clue: Feature-rich, well-established, free tier, iOS and Android. GDPR provides meaningful protections that US law doesn't. For users comfortable with cloud storage under strong regulation, Clue is the best of that category.
The tradeoff: Cloud-based. Your data exists on servers in Germany. MLAT requests can reach German companies. GDPR slows legal access but doesn't eliminate it. Clue is still a company holding your data, better-regulated than Flo, but architecturally similar.
How to Decide
Maximum privacy: Floriva (if you need iOS or sync) or Drip (if you're on Android and want open-source verification).
Maximum privacy + free: Euki (iOS + Android) or Drip (Android only).
Most features + reasonable privacy: Clue. Understand that cloud-based means your data exists on servers, even well-regulated ones.
Switching from Flo: Export your Flo data first. See the switching from Flo guide for steps. None of these alternatives import directly from Flo, you'll likely re-enter historical data manually.

The Privacy Bottom Line
Flo's settlement proved that privacy policies are only as good as the company's willingness to follow them. Flo promised privacy and shared data with Facebook. The FTC intervened. A $59.5M settlement was reached. And Flo's servers still hold user data.
The lesson isn't to find a cloud app with a better privacy policy. The lesson is that on-device storage eliminates the risk entirely. When the data isn't on a server, there's nothing to share with Facebook, nothing to subpoena, and nothing to settle a class action over.

Quick answers to the obvious questions.
What is the best period tracker after the Flo settlement?
The most private alternatives to Flo are trackers built around device storage: Floriva (iOS + Android, paid app with no free tier, optional encrypted sync), Euki (iOS + Android, free, nonprofit-backed), and Drip (Android-only, free, open-source). For users who prefer cloud storage with strong regulation, Clue is GDPR-regulated in Germany. The key difference: Floriva has no readable central cycle database. Cloud apps, even well-regulated ones, store readable data that can be accessed through legal process.
What period tracker doesn't share data with Facebook?
On-device period trackers reduce third-party sharing risk because core records stay on your device. Floriva does not have a readable central cycle database to share. Flo's FTC enforcement and settlement resulted from data sharing with third parties. Device-first architecture is built to avoid that exposure.
Questions people ask before they switch.
What happened with the Flo settlement?
In September 2025, a combined $59.5M settlement resolved class action lawsuits against Flo Health, Google, and Flurry over sharing user reproductive health data. The FTC had previously taken enforcement action against Flo in 2021 for sharing period data with Facebook and Google without user consent.
Is Flo safe to use now?
Flo launched Anonymous Mode after the FTC action, but it requires a premium subscription. The underlying architecture remains cloud-based. Your data still lives on Flo's servers and can be subpoenaed.
Can I export my data from Flo before switching?
Flo offers a data export function under GDPR and privacy regulations. Export your data before deleting your account. On-device trackers like Floriva, Euki, and Drip do not import from Flo directly, so you may need to re-enter historical data manually.
Is Clue the same as Flo?
No. Clue is a German company operating under GDPR with different privacy practices than Flo. Clue has not faced FTC enforcement. But Clue is still cloud-based. Your data exists on their servers in Germany. GDPR provides stronger protections than US law, but the data is still stored on a server.
