What we collect
When you submit a product: the link, the optional note you write, and the information we read from that product's public website. We do not store who submitted it. Your IP address is used briefly in memory to limit how often one person can submit, and is not saved.
When you sign in: your email address and the basic profile details Google or GitHub share with us, and the channel that first brought you here (for example a link with ?ref=), which is kept in your browser for up to 30 days and saved with your account when you sign in.
When you click through to a product: a daily count of clicks per listing. The count does not include who clicked.
Page views: we use Vercel Web Analytics, which counts visits without cookies.
How we use it
Only to run the Service: to build and show listings, to let you sign in, and to understand which pages and channels people use. We do not sell your data or share it beyond the processors below.
Processors
Supabase (database and sign-in), Vercel (hosting, analytics, and the AI service that reads product websites), Anthropic (the AI model behind that service, which receives the text of the product's website, not data about you), and Google and GitHub (sign-in).
Deletion
To delete your account, or to have a listing of your product corrected or removed, contact us.
