Alivenia tracks your cycle and symptoms entirely on your device — encrypted with AES-256, no account required, no data ever leaving your phone.
Fully featured cycle tracking that takes seconds to use — and keeps every data point private.
Learns your pattern over time and estimates your next period, fertile window, and ovulation date — getting more accurate with every logged cycle.
Log energy, mood, pain, sleep, and physical symptoms in under 3 seconds. Tap once — you're done. No typing required, ever.
Visualize patterns across cycles — symptom frequency, mood correlations, energy trends, and cycle length variation — surfaced automatically over time.
Export a formatted PDF summary of your cycle history and symptoms — formatted for a clinical conversation, entirely generated on your device.
Back up your data to a passphrase-protected file you keep. Restore it on a new device. Your key, your file — we never touch it.
Optional local notifications for period predictions, fertile windows, and logging reminders. Scheduled entirely on your device — no server involved.
That is not a marketing line — it is a technical fact. Here is how it works.
We have no sign-up flow because we have no user database. Nothing to breach, nothing to subpoena, nothing to lose.
Your database is encrypted with a key derived from a secret stored in your device's secure enclave. Unreadable to us or anyone else.
No crash reporters, no usage analytics, no third-party SDKs phoning home. The app works fully offline and makes zero network requests.
We do not ask for your name, location, age, or any identifying detail. The app genuinely does not need to know who you are.
Your backup is an encrypted binary file that only your passphrase can open. We never see it, store it, or touch it.
Alivenia is in development. Add your email to hear when it launches — or just check back.
We wrote this ourselves, in plain language. It is short because there is not much to say.

Alivenia is a local-only app. All data you enter is stored on your device using an AES-256 encrypted SQLite database. We do not collect, transmit, store, or have access to any information you enter into the app.
What we collect: Nothing. We do not collect your name, email address, location, device identifiers, usage data, or any other information.
Analytics and crash reporting: None. The app contains no analytics SDK, no crash reporter, and no third-party code that makes network requests.
Backups: If you use the backup feature, the backup file is encrypted on your device before you save it. We never receive or handle your backup file. You control where it goes.
Notifications: If you enable reminders, they are scheduled locally on your device. We do not use push notification services.
Network access: The app does not request internet permission. It is incapable of transmitting data over the network.
Children: The app does not collect data from anyone, including users under 13.
Changes: If this policy ever changes in a meaningful way, the change will be noted in the app update release notes.
