Picture

The application is for people who choose not to use Google services, including the Firebase Push, which is known to expose metadata to various third parties. Without FCM/GCM push, most users must enable 'keep alive' and 'background connection' features, which cause excessive battery consumption. Not so with Optogram, which uses Unified Push, which is enabled automatically when using a companion application Ntfy that uses publicly available (or your own) push servers.

Credits: This application won't be possible without F-Droid's TelegramFOSS, Mercurygram and Ntfy application developments.
