This is a small side project. Here is everything it stores, in full:
An anonymous device cookie plus a hashed (not stored raw) IP address are used to count unique visitors and people currently on the page — the “reading now” and “visitors since launch” numbers in the header. No name, account, or identity is attached to this — it’s a one-way hash used only for counting.
Registering a board stores the URL and, if you provide one, an email address — used only to contact you if the listing breaks. It is never shown publicly and never sold or shared.
Buying an ad slot stores the name, URL, tagline, and email you submit, plus Stripe’s own checkout/payment identifiers. Payment details themselves are handled entirely by Stripe — this site never sees or stores your card number.
Supabase (database) and Stripe (payments) process data on our behalf under their own privacy policies. No analytics or advertising trackers are used beyond the first-party visitor counting described above.
