Privacy Policy

Beta. Last updated November 11, 2026.

What we collect

• Your mobile number (to sign you in) and optional email (for notices).
• Your username, which is the only name shown publicly.
• If you verify your ID: the result, your verified legal name (stored encrypted), and whether you are 18 or older. We do not store your ID document, ID number, selfie or date of birth. Stripe processes and retains those under its own policy.
• Photos you take of your slabs, the one-time code, timestamps and your device type.
• The cert numbers and card details you register, and the ownership history.

Why

To vouch that a verified person held a specific slab on a specific date, to prevent and investigate fraud, and to contact you about your cards.

What is public

Card pages show your username, shop name if you are a vendor, the card details, the front photo of an approved claim, and dates. Never your legal name, phone, email or back photos.

Sharing

Service providers only: Supabase (database and storage), Twilio (text codes), Stripe (ID checks), Resend (email), Cloudflare (hosting). We may share records with law enforcement when legally required or to investigate fraud.

Retention and deletion

Ownership history is permanent by design. Superseded claim photos are deleted after 12 months. Email hello@slabowner.com to delete your account; we keep the minimum needed to preserve the ownership log and investigate fraud.

California residents

You may request access to or deletion of your personal information by emailing hello@slabowner.com. We do not sell personal information.
