We respond within 48 hours. Include your Texrr username if relevant to your issue.
Texrr is a device-to-device encrypted messenger. Messages are encrypted on your phone using AES-256 and sent directly to the recipient via WebRTC peer-to-peer connections. No server ever sees your message content. Each message is an individual send — like encrypted email — not a continuous chat thread.
Texrr costs $4.99/year (auto-renewing) or $29.99 for lifetime access. Payment is handled entirely by the App Store or Google Play. We never see your payment details.
There is no user search in Texrr. To add a contact, you must scan their QR code or they must scan yours. In the app, tap the QR icon to display your code or open the scanner. You can also share your QR code as an image through another channel — but both parties must complete the exchange before messages can be sent. This is by design: no one can message you unless you've directly shared your QR code with them.
Yes. When composing a new message, you can select multiple recipients. Each recipient receives their own individually encrypted copy sent via their own peer-to-peer connection. Recipients do not see who else received the message unless you include that information in the message itself.
The message is queued on your device. When the recipient comes online, the encrypted message is delivered automatically via a peer-to-peer connection. The message never passes through or is stored on any server while waiting.
It means exactly that. If you lose your device and don't have a backup, your messages and encryption keys are gone forever. We cannot recover them. No one can. This is by design — it's what makes Texrr genuinely private. We cannot be forced to hand over data we do not have.
In the app, go to Settings → Data → Export Vault. This creates an encrypted backup of your messages, keys, and hash chains. Save the backup file wherever you choose — a USB drive, external storage, cloud storage you control. Texrr never has a copy of your backup.
Every message you send or receive is hashed and linked to the previous message in a chain — like a mini blockchain. Every 10 messages, a Merkle proof genesis block is created. Every 50 messages, the chain's integrity is verified automatically. If anything has been tampered with — a message altered, an account taken over, a hash mismatch — the verification fails and the contact is flagged in your inbox.
A flag means the hash chain verification for that contact failed. This could mean a hash mismatch (data was altered), a UUID change (the person may have switched devices without properly re-establishing their identity), a proof failure, or a broken chain. You can view the details in the Verify screen and decide whether to continue communicating with that contact or block them.
Three things: your email address, your username, and your public key. That's it. Two database tables. No message table exists. There is no user search or directory — you cannot look up other users on our server. Messages, encryption keys, hash chains, Merkle proofs, vault data, and backups never touch our server. See our Enterprise Privacy Policy for full details.
In the app, go to Settings → Account → Delete Account. This permanently removes your email, username, and public key from our server. Local data on your device is not affected — uninstall the app to remove local data. If you cannot access the app, email texrr@132eng.com from your registered email address and we will delete your account manually.
Subscriptions are managed by Apple or Google, not by Texrr directly. On iOS, go to Settings → Apple ID → Subscriptions → Texrr → Cancel. On Android, go to Google Play → Menu → Subscriptions → Texrr → Cancel. Cancel at least 24 hours before your renewal date. Lifetime purchases do not renew and cannot be cancelled.
Open a message from the person you want to block and tap the block icon. You can also block from Settings → Security → Blocked Users. Blocked users cannot send you messages. You can unblock at any time from the same screen.
Email texrr@132eng.com with the username of the account you wish to report and a description of the issue. Because messages are encrypted, we cannot see message content — but we can take account-level action including suspension and termination.
