FAQ

Where do I find my Device Code? ▾

If the app is not activated, it shows “Subscription required / Access is blocked” and displays your Device Code. Copy it and send it via Telegram for activation.

Why do I need “Exact alarms” / “Unrestricted battery”? ▾

These settings help scheduled sending run reliably in the background — especially on Samsung devices.
