Trust and security

You hand us photos, an eBay sign-in and a card. Here is what happens to each, in plain words.

Your photos

  • Photos are kept in private storage in the United States. Nobody can open one with a plain web address.
  • When the app shows you a photo, it uses a link that stops working after two hours.
  • Delete a scan, an item or your account and its photos are deleted with it.

Your eBay account

  • You sign in on eBay's own site. We never see or store your eBay password.
  • The key eBay gives us to list for you is stored encrypted. The same goes for Discogs and Bonanza.
  • A listing goes live only when you publish it, or when you have switched on automatic relisting.
  • Disconnect eBay in Settings and we delete the connection.
  • You can also take away our access at any time from your eBay account settings.

Your card

  • Payments run through Stripe. Your card number goes to Stripe and never reaches us.
  • We keep an ID that points to your Stripe record so we know what you bought. We do not keep a card number, not even the last four digits.

Your data is yours

  • We do not sell your personal information.
  • You can download your items and your scans as spreadsheet files.
  • Deleting your account deletes your items, scans, photos and eBay connection. We keep a record that the account was deleted and, if you paid, the ID of its Stripe record.

Your sign-in

  • Passwords are stored scrambled, never as typed, so nobody here can read yours.
  • You can sign in with Google or Apple and skip a password with us altogether.
  • Five wrong passwords lock sign-in for 15 minutes, and you can turn on a second step at sign-in.

How the AI sees your item

  • Your photo is sent to Claude, an AI model made by Anthropic, to name the item and read its details.
  • To find matching sales, a smaller copy of a photo can be sent to eBay's image search with no account details attached.

Keeping it running

  • An automated check tests the app and its database every hour and tells us if something is wrong.
  • Our hosting, database and photo storage are all in the United States.
