Prism Flow is a minimal habit tracker and data-visualization tool. We make a firm commitment: your data belongs to you alone. We never collect, store, or share any personal information.

What We Collect

We collect nothing. Prism Flow has no account system, no servers, no analytics, and no advertising SDK. Everything runs entirely on your device.

Data Storage

All your habits, check-in records, notes, and other data are stored only in your device's local storage (SQLite). Preferences (theme, nickname, etc.) are stored locally on your device. We do not use cloud sync and never upload any data.

Local Notifications

When you create a habit reminder, the app schedules local notifications on your device. Notification content is generated locally and is never sent to us or any third party.

In-App Purchase

If you upgrade to Pro, payment is processed by Apple (App Store). We only receive a success/failure status, never your payment details. Subscriptions can be restored after reinstall via "Restore Purchase" in the app.

Your Rights

Because we collect no data, there is nothing of yours for us to delete or share. You can export your own check-in records (CSV) from within the app at any time. Uninstalling the app removes all local data on your device.

Children's Privacy

This app is suitable for all ages and collects no personal information, so no special handling is required.
