privacy.

StackPulse is a non-profit, open-source service that helps developers track GitHub release notes for the libraries they use. We try to collect as little as possible. This page explains what we collect, why, and what your rights are.

What we collect

• GitHub profile basics when you sign in: your numeric GitHub user ID, email address, display name, and avatar URL. Authentication is handled by Better Auth.
• Your stack selection: the list of technologies and GitHub repository URLs you choose to follow.
• AI upgrade questions if you ask about a release: your question, optional current version, and optional project context you type into the form.
• Digest signup email if you subscribe from a public page without signing in. We store the email address, signup source, and optional stack slug you subscribed from.
• Session cookies needed to keep you signed in.
• Server logsgenerated by our hosting provider (Vercel) — IP address, user agent, request path, response status. These are retained on Vercel's schedule.

What we don't collect

• No third-party trackers or advertising pixels.
• No behavioural analytics that profile individuals.
• No access to your private GitHub repos. The OAuth scope is your public profile only.

How we use it

• To show you a personalised feed of releases.
• To send your selected repos through GitHub's public release API twice a day.
• To summarise release notes using OpenRouter (model details are public).
• To answer release upgrade questions using OpenRouter when you explicitly submit one.
• To respond to support requests you send us.
• To send opt-in release and upgrade digests if you subscribe on a public page.

Where it lives

Account data and release summaries are stored in Postgres on Neon (neon.tech), inside the EU/US region you signed up from. The app is hosted on Vercel. Release notes and AI upgrade questions are sent to OpenRouter when AI features run. We do not sell your data.

Your rights

• Access: sign in and you can see your full stack and feed.
• Deletion:sign in, open the user menu, click "delete account". This wipes your account, stack, and read history immediately and cannot be undone.
• Questions: open an issue at github.com/daniel-ctn/stack-pulse.

Changes

If this policy ever changes meaningfully, we'll update the date at the top and post a note in the repo's release notes — since you'll already be watching for those.
