Privacy Policy

Crowns is a personal Chrome extension that displays your Oura Ring data on your browser's new tab page.

What we handle

• When you connect via OAuth, Crowns receives an Oura access token and refresh token. These are stored locally in your browser and sent to the Crowns backend only to exchange or refresh tokens with Oura.
• The Crowns backend does not store your tokens or any health data. It relays the OAuth token exchange between your browser and Oura and keeps nothing.
• Your Oura health data (sleep, activity, readiness) is fetched directly by the extension and cached locally in your browser. It is never sent to or stored on the Crowns backend.

What we don't do

• No analytics or tracking.
• No selling or sharing of your data.
• No third parties other than Oura's own API.

Removing your data

Removing the extension (or clearing its storage) deletes all locally stored tokens and cached data.
