Email glongptech@gmail.com. We aim to reply within 2 business days. Please include your device model, OS version and app version. Never send your recovery phrase to anyone, including us. We will never ask for it.
No. The 12-word phrase is the only key to your account, messages and vault, and it never leaves your device, so we do not have a copy. Without it the data cannot be recovered by anyone. Back it up now: Profile → Backup.
Check that notifications are enabled for GLongP, that battery optimisation is not restricting the app (Android), and that you are not in Do Not Disturb or Focus. On Android, some manufacturers require the app to be allowed to start in the background.
This is usually a network restriction. Try switching between Wi-Fi and mobile data. Strict corporate or carrier networks can block the direct connection between devices.
Install GLongP on the new device and restore with your 12-word recovery phrase (Profile → Restore). Your account and identity come back. Message history stored only on the old device does not transfer.
Yes. Messages are encrypted on your device with a key derived from your key and the recipient's public key. Our relay server only passes ciphertext. See the Privacy Policy for details.
Open the chat or the group member list and choose Block or report. Blocking drops their messages and calls on your device immediately. Reports reach us and are reviewed within 24 hours.
In the app: Profile → Delete account. This deletes your server-side data and wipes the device in one step. If you no longer have the app, see Delete Your Data.
