DataLeft — Privacy Policy
Effective date: July 13, 2026
DataLeft collects no data. None. Everything stays on your device.
What we collect
Nothing. DataLeft has no server, no account system, no analytics SDK, no advertising SDK, and no VPN. The app never transmits your data anywhere.
What stays on your device
- Network usage readings from your device's public system counters
- Your data plans (name, limit, dates) that you enter
- Notification preferences
All of this is stored only in the app's local database on your device (and its widget's shared container). Deleting the app deletes all of it.
Notifications
Usage alerts are generated locally on your device. No push server is involved.
Purchases
DataLeft Pro is a one-time purchase processed entirely by Apple through the App Store. We never see your payment information.
