What Footprint OnChain collects, why, and what we never do with it. Last updated: November 2026.
Account details: your name, business, email, and phone, so we can run your service and send alerts. Protected-site details: the websites and domains you register with us. Content fingerprints: SHA-256 hashes of your website's pages, photos, and files. A hash is a one-way fingerprint — it cannot be turned back into your content. Monitoring logs: when a protected fingerprint loads, we log the domain, page, time, and visitor IP address; that log is the core of the service and of your evidence pack.
Only to provide the service: registering and monitoring your sites, timestamping fingerprints (only the hash — never your files — is submitted to the public OpenTimestamps calendars for Bitcoin anchoring), emailing you setup confirmations and alerts, and preparing evidence packs at your request.
We do not sell your information. We do not share your details with third parties except the processors needed to run the service (such as our email delivery provider), and we do not upload your website files to any blockchain — only their hashes.
If you tick the SMS opt-in box on our contact form or ask us to add your number when signing up, we use your mobile number only to send the texts described in our SMS Policy — enquiry follow-ups, setup confirmations, and suspected-copy alerts. Your number is never sold or shared with third parties for their marketing. Reply STOP to any text to opt out at any time.
Service email — setup confirmations, suspected-copy alerts, evidence packs, and replies to your enquiries — is part of the service itself. Occasional updates about the service may be sent as described in our Email Policy, and you can opt out of those updates at any time.
Ask us any time what we hold about you or your sites, and to correct or delete it; deleting your account deletes your sites, stamps, and logs with it. Email contact@info.footprintonchain.com or call 510-619-0213.
