Support

UnboundChat uses OpenRouter to access AI models. Sign up for a free account, open the Keyspage, generate a new key, and paste it into UnboundChat's Settings → API Key. Your key is stored in protected device storage; if you enable key sync, only an encrypted copy is uploaded.

Conversations live in a local database on your device. If you turn on sync, content is encrypted before upload using key material established on your device — we do not hold the key needed to read your messages, titles, or attachments. See the Security page for full technical details.

Open Settings → Sync and sign in with email, Google, Apple on supported devices, or a recovery-phrase account. Email and provider accounts use the same separate sync passphrase on each device; recovery-phrase accounts derive their sync-key inputs from the phrase. Sync is optional; stored chats and settings remain available locally without it.

OpenRouter offers models tagged :free in the model picker. Provider limits and policies still apply. Supported non-Apple builds may also offer a small app-managed free tier that routes requests through an UnboundChat service before OpenRouter.

Use a conversation's Export action to save that conversation as JSON, Markdown, plain text, or PDF. For a restorable app archive, open Settings → Data → Backup & Restore. Backups can be protected with a password; an unprotected export or backup must be secured by you.

If you are signed in, use Settings → Advanced Settings → Danger zone → Delete account. You can also submit a verified request without opening the app on the account deletion page.

Use the contact form below — include your platform (Windows, Android, iOS, macOS), the app version (Settings → About), and as much detail as you can about what happened. Screenshots help a lot.
