Flo is the most-downloaded period tracker, with a polished free tier funded by a paid subscription (Flo Premium) and advertising. It is a cloud app: you create an account, and your data is processed on Flo's servers. In January 2021, the U.S. Federal Trade Commission announced a settlement with Flo Health over allegations that the app shared users' health information with third parties, including Facebook and Google, despite promising to keep it private. Flo has since added features like "Anonymous Mode."
Hoo-Ha's approach is structurally different: there is no account, no server, and no networking code in the app at all, so there is nothing to share even by accident. If you're looking for a private alternative to Flo with a one-time price instead of a subscription, that's exactly what Hoo-Ha is built to be.
Clue is a well-regarded, science-focused tracker based in Germany and subject to GDPR, with a free tier and a paid Clue Plus subscription. It is generally more privacy-conscious than the average tracker, but it is still a cloud service that uses an account and stores data on its servers. If your priority is that your cycle data never leaves your phone — and a one-time payment over a subscription — Hoo-Ha is the more private, lower-cost choice.
The private Flo alternative — for people leaving Flo over privacy or the subscription.
Hoo-Ha vs Natural Cycles — a private cycle tracker vs an FDA-cleared birth-control app (and why that difference matters).
Hoo-Ha vs Stardust — two privacy-first trackers, and which one is actually offline.
Hoo-Ha vs Drip — two offline trackers; open-source Android vs full-featured iPhone.
