Why an offline period tracker matters
Most period and menstrual tracking apps are cloud services. You make an account, and your most sensitive health data — cycle dates, symptoms, sexual activity, pregnancy status — is uploaded to a company's servers, where it can be analyzed, monetized, breached, or subpoenaed. An offline period tracker removes that entire category of risk: if the data never leaves your phone, there is nothing to leak.
How Hoo-Ha stays offline
- No networking code. The app literally cannot make a network request. A check runs every time the app is built and fails the build if any networking code is ever added.
- No account, no sign-up. Open the app and start logging. There's no email, no password, no profile on a server somewhere.
- Encrypted on device. Sensitive fields are encrypted with AES-GCM using a key stored in your iPhone's Keychain. The database itself is protected by iOS file-level encryption while your phone is locked.
- Works in airplane mode. Wifi off, cellular off — Hoo-Ha works exactly the same, because it never needed a connection in the first place.
You're still in control of exports
Offline doesn't mean trapped. You can export your data to a spreadsheet or create an encrypted, passphrase-protected backup whenever you want — those files are created on your device, and you decide if and where they go. You can also import from Apple Health and other apps.
Looking for a period tracker that works without internet? That's the whole idea behind Hoo-Ha — a fully offline, encrypted tracker for iPhone. Try free for 14 days, then $1.99/mo, $19.99/yr, or $39.99 once for lifetime.
