yLauncher - Privacy Policy

Last updated: March 27, 2026

Overview

yLauncher is an open-source Android launcher. Your privacy is important to us. This policy explains what data the app accesses and how it is handled.

Data collection and usage

yLauncher does not collect, store, reuse, or share any personal data whatsoever. All your data (favorites, folders, settings, preferences) exists locally on your device only. No data ever leaves your device. There are no servers, no analytics, no tracking, and no data reuse of any kind.

Permissions

yLauncher requests the following permissions, all used exclusively for launcher functionality:

• Query all packages — Required to list and launch installed apps, which is the core function of a home launcher.
• Notification access — Used to display notification badges and previews next to your favorite apps on the home screen. Notification content is only read locally and never stored or transmitted.
• Usage stats — Used to suggest frequently and recently used apps. This data is read locally and never leaves your device.
• Bind app widgets — Used to display home screen widgets.
• Billing — Used for the optional "Buy me a coffee" donation feature via Google Play.

In-app purchases

yLauncher offers an optional one-time donation ("Buy me a coffee") through Google Play Billing. No purchase is required to use any feature of the app. Purchase transactions are handled entirely by Google Play.

Third-party services

yLauncher does not integrate any third-party analytics, advertising, or tracking services. The only third-party service used is Google Play Billing for optional donations.

Data retention and deletion

yLauncher does not collect or store any data on external servers. All data (favorites, folders, settings, preferences) is stored locally on your device only and is retained for as long as the app is installed.

To delete all app data, you can use the standard Android mechanism: go to Settings > Apps > yLauncher > Storage > Clear data. Uninstalling the app will also remove all locally stored data.

Children's privacy

yLauncher does not knowingly collect any data from children. The app does not collect data from anyone.

Open source

yLauncher is open source under the GPL v3 license. You can review the complete source code at github.com/ykatchou/ylauncher.
