Privacy Policy

What we collect

We collect the information needed to operate Changes.Watch: email addresses, selected products, watchlist preferences, product suggestions, claim requests, and release reactions.

How we use it

We use this information to provide watchlists, send weekly digests when requested, improve the catalog, prevent duplicate voting, and understand whether Changes.Watch is useful.

Private stack discovery

AI Stack Discovery does not require Gmail access. If you paste a Google connected-apps list, app names and domains are matched in your browser against the public Changes.Watch catalog. Optional screenshots are shown locally as a reference and are not uploaded or parsed. We only save products you explicitly add to your watchlist.

Google account sign-in

Google sign-in uses only the basic account scopes needed to identify your account: openid, email, and profile. It does not request Gmail, Drive, Calendar, or connected-app access. The OAuth callback is handled on changes.watch before creating a Changes.Watch session through Supabase Auth.

Analytics and email

We use analytics and email delivery providers to measure page views, signup flow performance, watched products, reactions, source clicks, and digest engagement. This may include Google Analytics, Vercel Analytics, PostHog, Supabase, and Resend.

Google Analytics may process device, browser, approximate location, traffic source, and interaction data to help us understand how people discover and use the site. You can use browser privacy controls, ad blockers, or Google's available opt-out tools to limit this tracking.

Your choices

You can unsubscribe from digest emails and request deletion or correction of your data by contacting hello@changes.watch.
