Frequently Asked Questions
Why should I use Realert?
Realert is the most secure and private way to save notification history on Android. Unlike other tools that send your chats to third-party cloud servers or drain battery, Realert operates 100% locally on your phone with zero telemetry, zero accounts, and zero cloud uploads.
How does Realert recover deleted messages?
When a message arrives, Android generates a notification preview. Realert utilizes Android’s official NotificationListenerService to store this preview in a secure local database on your phone. When a sender deletes a message later, Realert retains the copy captured when the notification first arrived.
Are my messages, photos, or voice notes ever sent to external servers?
Absolutely not. Realert is designed with a strict zero-knowledge architecture. All notification history, chat media, and voice recordings remain exclusively on your physical Android device. There is no cloud sync, no central database, and no server telemetry.
How can I ensure Realert works reliably without being stopped by battery optimization?
Some manufacturers (such as Samsung, Xiaomi, and Oppo) enforce aggressive battery optimization that kills background services. To ensure uninterrupted recovery, disable battery optimization for Realert and allow it to auto-start in your device settings. Detailed step-by-step guides are available at docs.diouane.com.
Which messaging apps are supported?
Realert works with any Android application that displays message notifications with text previews, including WhatsApp, WhatsApp Business, Instagram Direct, Telegram, Facebook Messenger, Signal, Discord, and X.
