Flo App Alternative: Period Trackers That Don't Sell Data
Looking for a Flo alternative? We document what Flo did with your data and which period trackers keep core records on your device.
The best Flo alternative for data privacy is Floriva. Flo settled a $59.5M class action in 2025 for sharing user health data with Facebook and Google. Floriva keeps core records on your device, does not sell cycle data, and has no readable central cycle database.
Why Users Are Leaving Flo
The FTC took enforcement action against Flo Health in January 2021. The agency found the company shared user health data, including period dates, pregnancy status, and detailed symptom information, with Facebook, Google, and third-party analytics firms. The data was shared through embedded software development kits (SDKs) without user consent, despite Flo's stated privacy commitments. This is the same pattern documented across data brokers trafficking in reproductive health data.
In September 2025, a combined $59.5M class action settlement resolved claims by millions of Flo users. On August 1, 2025, a jury separately found Meta liable for accessing user data from the Flo app.
This is not a policy dispute. It is a documented, FTC-sanctioned, jury-confirmed pattern of sharing intimate health data with advertising infrastructure.
The Architecture Problem
Flo's Anonymous Mode, launched after the FTC enforcement action, puts privacy behind a paywall. But the core problem is architectural, not a policy matter. Flo stores your data on its servers. Any policy Flo adopts can be changed, pressured by law enforcement, or overridden by a court order. That is a real risk in post-Dobbs states.
The only reliable way to prevent data from being subpoenaed is to ensure it never reaches a centralized server. That is the on-device storage approach.
How Floriva Compares
Floriva is built around the architecture choice that Flo's Anonymous Mode simulates: core records stay on your device. We cannot sell readable cycle data we do not have. If sync is on, Floriva only receives end-to-end encrypted data that we cannot read.
How to Switch Without Losing Your History
If you are leaving Flo, export your data before you delete your account. In Flo, go to Settings, then Privacy, then Request My Data. Save the export first, enter your last few cycle starts into your new tracker, and only then delete the Flo account itself instead of just uninstalling the app.

Questions people ask before they switch.
Did Flo sell my period data?
The FTC found that Flo shared user health data, including menstrual cycle information, with Facebook, Google, and third-party analytics providers despite promising privacy. The FTC took enforcement action against Flo in 2021. A combined $59.5M class action settlement was reached in September 2025.
Is Flo safe to use after the FTC enforcement action?
Flo launched Anonymous Mode after the FTC enforcement action, but this requires a premium subscription. The underlying architecture remains cloud-based, meaning your data exists on Flo's servers and is accessible to law enforcement via subpoena.
What period tracker can't be subpoenaed?
Trackers that store core data on your device reduce what the company can produce from its own systems. Floriva, Drip (Android), and Euki use device-first storage. Device searches are a separate legal path.
