Privacy Policy — L.a1.ncher
Last updated: 10 August 2026
L.a1.ncher is an Android launcher with a built-in assistant. Its core promise is simple: your data stays on your device.
What the app processes, and where

On device
The app has no server. The developer receives none of this data. There are no ads, no advertising ID, no analytics SDKs, and no trackers.
When data does leave your device
Only in cases you explicitly configure:
Cloud AI key (optional). If you connect your own API key (e.g. Gemini or an OpenAI-compatible endpoint), your chat messages and the minimal personal context needed to answer (routine summaries, pending bills, current time) are sent to that provider, under that provider's privacy policy. Skip this and use the on-device model, and nothing is sent.
Weather (optional). Approximate coordinates are sent to Open-Meteo, a keyless, no-account weather API, to fetch the forecast.
Telegram bridge (optional). If you configure your own bot token, messages you exchange with your bot go through Telegram's Bot API. The token is stored encrypted on the device.
Home Assistant (optional). Commands you issue are sent to the Home Assistant address you provide, typically on your own network. The token is stored encrypted.
RSS feeds (optional). The app fetches the feed URLs you add.
Accessibility service
If you grant the optional accessibility permission, the app reads only the package name of the app currently in the foreground — not its content, not what you type, not your passwords. It is used for two things: offering suggestions at the right moment, and running macros you configured with an "when this app opens" trigger. This information never leaves your phone, is not sent to any server, is not stored, and is not shared with anyone. The app works without this permission; you can decline it or revoke it at any time in Android Settings.
Storage and security
All learned data lives in a local database in the app's private storage.
Secrets (bot tokens, smart-home tokens, AI keys) are stored using Android's EncryptedSharedPreferences.
Uninstalling the app deletes all of it.
Data deletion
Everything is local: clear the app's storage or uninstall it to erase all learned data. Blocked-notification rules, learned patterns, and stored memories can also be removed individually inside the app.
Children
The app is not directed at children under 13.
