Privacy model
Why OpenThena can't leak what it never stores.
OpenThena's privacy is structural. These guarantees come from how the app is built, not from a promise in a policy document.
What we never do
- No database — conversations are never persisted server-side.
- No accounts — there is nothing to sign up for.
- No server logs of message content.
- No analytics, fingerprinting, or advertising cookies.
Where your data lives
Your chat history is saved in your browser's localStorage under the key openthena.conversations.v1. It never leaves your device. Clearing a conversation — or your browser data — erases it permanently.
The only network call with your message is the streaming request to the model provider you configured. OpenThena adds no logging in between.
A note on providers
Your prompts are sent to the upstream model (e.g. Xiaomi MiMo) to generate a response. Their data handling is governed by their terms. For maximum control, route through a self-hosted LiteLLM proxy or a local model.
