Privacy Policy

Last updated: July 6, 2026

Yearline is a one-line-a-day diary for Android, built to be private by architecture, not by promise. This page explains — in plain language, because that's all that's needed — what happens with your data. The short version: everything stays on your device, and we collect nothing.

What data Yearline stores

Your diary entries, your settings (language, reminder time, theme) and your streak are stored in a local SQLite database inside the app's private storage on your phone. That's all, and it never leaves your device through us.

What data we collect

None. Yearline has no backend, no user accounts, no analytics SDK, no crash-reporting SDK, no advertising and no tracking of any kind. We do not know who you are, when you write, or what you write. We couldn't read your diary even if we wanted to — there is no server for it to be sent to.

Purchases

If you buy Yearline Premium, the purchase is processed by Google Play and managed through RevenueCat, our subscription-management provider. RevenueCat receives a pseudonymous purchase identifier — never your diary content, name or email. See RevenueCat's privacy policy. Google Play's own handling of your payment data is covered by Google's privacy policy.

Notifications

The optional daily reminder is scheduled locally on your device. It never touches a server.

Exports and backups

When you export your diary (JSON for everyone, PDF with Premium), the file is generated on your device and saved or shared wherever you choose. Future backup features will upload only to storage you own and connect yourself (such as your personal Google Drive), never to us.

Your rights

Because your data never reaches us, exercising your rights is delightfully simple: everything is already in your hands. You can export your data at any time from Settings, and deleting the app deletes your local data. There is nothing on our side to request, correct or erase.

Children

Yearline is not directed at children under 13 and collects no data from anyone, children included.

Changes to this policy

If we ever change how Yearline handles data — for example, when optional cloud backup ships — we will update this page and note it in the app's changelog before the change takes effect. The local-first principle is not up for revision.
