How can we help?

Your identity is a cryptographic keypair generated on your device at first launch and registered on Polygon. There is no phone number, no email and no password, so there is nothing for anyone to reset, leak or take away.

Only from your own backup. Snapchain never holds a copy of your keys, so without a backup the identity cannot be restored — not by us, not by anyone. Create one now in Settings → Backups and keep it somewhere safe and offline.

The PIN is verified locally on your device and cannot be reset remotely. Reinstall the app and restore from your key backup.

This is almost always the node connection. Open Settings → RPC Configuration and check that the current node shows as online. Switch to the public resolver, or enter your own endpoint, then save the configuration.

Contacts → Add Contact. Search by nickname, or paste a wallet address directly. Nothing is ever uploaded from your phone's address book.

No. Messages are encrypted on the sender's device and can only be decrypted with the recipient's key. Our servers only relay silent wake-up notifications and hold encrypted attachments we cannot decrypt, so we have no way to inspect, moderate or hand over conversation content.

Everything is stored on your device: clearing the app data or uninstalling Snapchain removes it. To remove your push notification registration from our servers, email us from the address below with your public wallet address. Data written to the blockchain is permanent and cannot be deleted.
