The Service may collect the following information:
- GitHub account information: When you sign in, the Service obtains your GitHub user ID, login name, display name, and avatar image URL via GitHub OAuth. We do not collect your password or email address.
- Usage data: Records of actions you take on the Service, such as items you add to your watchlist or OSS submissions.
- Access logs: The Service runs on Cloudflare's infrastructure, which generates standard access logs (including IP addresses). Please refer to Cloudflare's own privacy policy for details.

3. Cookies and Local Storage
The Service uses a session cookie to keep you signed in. Your progress through "Today's Discovery Pack" is stored in your browser's localStorage and is not sent to the server.
