In short: Alerta has no server of its own. Everything the app knows stays on your phone.
Alerta is an Android app that watches the Telegram chats you choose and raises a loud alarm when a new message arrives there. This policy explains what data the app processes, where it is stored and what leaves the device.
Who is responsible
Alerta (package uz.adizoff.tgalarm) is developed and distributed by Adizoff · HOSTIN.UZ. Privacy questions: support@itleader.uz.
What the app processes
Everything below is processed on the device itself, in the app's private storage, and is never sent to the developer.
- Telegram session — created when you sign in with your phone number. Stored by the TDLib library inside the app; the keys to it are kept in Android's encrypted storage.
- Phone number, login code and cloud password — entered during sign-in and sent straight to Telegram, exactly as any Telegram client does. The app does not keep them.
- Chat list, chat titles and photos — needed so you can pick what to watch.
- Text of incoming messages in the watched chats — read at the moment of arrival to compare it with your keywords and stop words. Conversations are not downloaded or archived.
- Settings and rules — watched chats, ringtone, volume, keywords, caller name.
- Alarm journal — time, chat title and a short fragment of the message that did or did not trigger the alarm. It can be cleared from the settings and keeps only recent entries.
What leaves the device
- Telegram servers. The app connects to Telegram directly through the official TDLib library under your account. Telegram's own processing is described in the Telegram Privacy Policy.
- Update check — only in the build downloaded from tgalarm.itleader.uz. It requests
/version.phpand sends its version number; the web server logs the IP address and time like any web server does. The store build has no update check at all.
What the app never does
It does not request location, camera, microphone, contacts, call log, SMS, or files beyond the ringtone you pick yourself. It contains no advertising or analytics libraries, collects no usage statistics and shares no data with third parties. It cannot send messages on your behalf — it only reacts to incoming ones.
Permissions and why they are needed
- Notifications — the persistent notification while watching, and the alarm itself.
- Display over other apps, full-screen alerts — so the alarm screen can appear from the lock screen.
- Background work, autostart, battery-optimisation exemption — so the Telegram connection survives sleep and returns after a reboot.
- Do Not Disturb access — optional, so the alarm is audible in silent mode.
- Install packages — only in the website build, for one-tap updates. The store build does not have this permission.
Storage and deletion
Data lives exactly as long as the app is installed. "Log out of Telegram" removes the session, "Clear journal" removes the alarm log. Uninstalling the app or clearing its data in Android settings erases everything at once. There is nothing to delete on the developer's side.
Children
The app is intended for adult Telegram users and is not directed at children. No children's data is collected deliberately.
Changes
If the app starts processing anything else, this page will be updated and the date at the top will change.
Trademarks
Alerta is an independent application, not affiliated with Telegram Messenger Inc. Telegram is mentioned only to describe what the app works with.
