What the app knows about you: nothing.

ETH Calendar is published by SeferLink and runs entirely on your device. This policy explains what that means in practice, section by section.

Data collection and sharing

ETH Calendar does not collect, transmit, sell, or share personal information. It has no user accounts, analytics, advertising SDKs, or internet permission. Calendar calculations and religious content are bundled with the app and work offline.

Permissions and device data

The app may ask for notification permission solely to show holiday, fasting, and reminder notifications chosen by you. It does not request access to location, contacts, photos, files, camera, microphone, SMS, call logs, or health data.

When you choose to add a day to your phone calendar, the app opens the device calendar's event editor. You review and save that event in your calendar app; ETH Calendar does not read, store, or upload calendar data.

On-device settings, retention, and deletion

Display preferences, language selection, and reminder settings are stored only on the device. They remain until you clear the app's storage or uninstall the app. If Android device backup is enabled, Android may restore these settings on another device. ETH Calendar does not receive or access that backup. There is no server-side user data to retain or delete.

Security

Because ETH Calendar does not transmit user data, no user data is sent over a network by the app.

Children

ETH Calendar does not collect data from children or adults.

Changes and contact

Any future change to these practices will be reflected in this policy before it is released. For privacy questions, write to Seferlink@gmail.com.
