Can I use two period trackers at once while switching?

Yes. Many users keep the old app running for a cycle or two while building confidence in the new one. Just don't enter data into both to avoid confusion.

What if my current tracker doesn't let me export data?

All major trackers do export. If yours doesn't, that's a red flag worth reconsidering. In the US you can request your data under CCPA (California) or state privacy laws.

Does switching delete my past cycle history from the old company's servers?

Not automatically. You need to delete your account and submit a formal deletion request (CCPA, GDPR, or state equivalent). Deleting the app alone does nothing to server-side data.

That trade looked acceptable until the enforcement record caught up. In 2021, the FTC ordered Flo Health to stop sharing user health data with Facebook, Google, and Flurry after finding that Flo had routed cycle and pregnancy events to those platforms through embedded SDKs. In September 2025, Flo settled a class action for $59.5M settlement over the same underlying conduct. Glow suffered a data leak in 2016 that exposed roughly 25M users' cycle and fertility records. Premom was caught by the FTC in 2023 sharing reproductive health data with Chinese analytics firms including Jiguang. The pattern is not one bad actor. It is an architecture. If a company holds your data on a server, that data can be shared, sold, breached, or subpoenaed. After the Supreme Court decision in Dobbs v. Jackson Women's Health Organization in 2022, the subpoena risk stopped being theoretical in states with abortion bans. Switching to on device storage removes the server from the equation. No server
