Privacy policy

Last updated 2026-08-08.

What we store, and why

• Your email address - to sign you in (magic links) and send alerts you asked for.
• Your listing content - the photos, description, and URLs of properties you register, plus mathematical fingerprints of them. This is the product: we compare the open web against these fingerprints.
• Evidence of suspected clones - screenshots and page copies of publicly visible pages that match your listings, kept as proof for takedowns.
• Checker submissions - URLs submitted to the public checker, and the submitter's IP address for rate-limiting only.

What we deliberately do not do

• No advertising, no trackers, no analytics cookies. Our only cookies are the sign-in session.
• We never sell or share your data with third parties, except the services that make the product run: email delivery (Resend) and payments (Gumroad - we never see your card details).
• We collect nothing about any person beyond the list above (data minimalism).

Deletion

Email [email protected] from your account address and we delete your account, properties, and fingerprints. Evidence of confirmed fraud may be retained where retention is legally appropriate.

Crawling

Our monitoring only visits public pages, identifies itself, and honors robots.txt - full policy on the bot page.

Shutdown Watch (/shutdowns)

Followers: we store your email, confirmation timestamps, the events you follow, and (for members) your tool watchlist and an encrypted copy of your license key for re-verification. Unsubscribing deletes the whole profile. Reminder emails (T-30/7/1) are sent only for deadlines you explicitly watch. Members' personal calendar feeds use an unguessable token stored only as a hash; re-activating rotates it, unsubscribing deletes it, and the token never appears in our logs.

Sponsors (Migration Slot): we store the sponsor name, link, pitch, verified transaction amounts/timestamps from Gumroad, and moderation state - kept while the placement is live and in the public bid history afterwards (amounts and relative times only). Sponsor emails are transactional (slot status), capped, and carry List-Unsubscribe; unsubscribing from marketing never blocks activation or receipt emails.
