The offline period tracker that never goes online

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.
