Privacy First
You’re in Control, Always
We built UnboundChat with privacy as a core principle, not an afterthought. Powerful features, zero compromises on your data ownership.
Your Own API Keys
Use your own API keys from OpenRouter, OpenAI, or Google. No middleman, no markup, complete transparency.
Local-First Storage
All conversations are stored locally on your device by default. Your chats stay with you unless you choose to sync.
Zero Data Retention
Enable ZDR mode to only use AI models that don’t store your conversations. Maximum privacy when you need it.
Encryption You Control
Cloud sync encrypts everything locally with your passphrase before upload. We never have access to your data — only you do.
Minimal Analytics
We use minimal, privacy-respecting analytics for troubleshooting only. You can disable it completely in settings.
