Sentinel is a background-alarm app that triggers a full-screen alarm when a Telegram message contains your keywords.

How it works:
• The app reads incoming Telegram notifications in the background
• Analyzes the text for your keywords and stopwords
• If there is a match, it triggers a full-screen alarm with sound and vibration
• If there is a stopword, the alarm does not trigger
• Keeps a log of all events

Key features:
• Support for official Telegram, Telegram X, Neko X
• Filter by specific channels or groups
• Setting the schedule for the alarm (by time)
• Flexible volume and alarm sound settings
• Recovery after device reboot
• Backup and restore of keywords

All data is stored exclusively on your device. The app does not send any data to external servers.

Requirements: Android 9 and above, access to notifications.

Attention: the application is an alarm clock based on Telegram notifications and is not a certified emergency alert system.
