123Hand is a hand-volume measurement app published by 123division. This policy explains what information the app handles, what is saved to your account, and how to delete it. The short version: we store your email, the name you give each scan, and the scan's date and measurement numbers. The images and 3D mesh never leave your iPhone.
123Hand requires an account so that scans can be saved to you. To create one you give us an email address and a password. We store the email and a salted hash of the password — we never see or store the password itself. There is no sign-in with Apple, Google or any other provider, and no social features.
For every scan you complete, the app sends a small record to our server:
That is all. The captured images, depth data and the 3D mesh are large files that stay in the app's own folder on your iPhone. They are never uploaded. You can see, share and delete them yourself in the Files app (On My iPhone › 123Hand) or from inside the app.
If you scan someone else's hand, you enter their name. Only do so with their permission, and tell them it is stored in your 123Hand account. You can delete any scan — and its name — at any time by swiping it away in the app, which removes it from our server as well.
123Hand asks for camera access because the scan is made with the camera and the LiDAR sensor. The camera is used only while you are scanning. Images are written to your device and nowhere else.
Only to run the app: to sign you in and to show you your scans. We do not use analytics, advertising, tracking or crash-reporting services, include no third-party SDKs, and do not sell, rent or share your data with anyone. The data is not used to track you across other apps or websites.
Account and scan records are stored on Cloudflare infrastructure (our hosting and database provider) and sent only over encrypted HTTPS. Session tokens are stored hashed on the server and in the iPhone Keychain on your device.
If you use the Share button to export a mesh or measurement, the file goes to the app or person you pick through the standard iOS share sheet. That is entirely under your control, and the recipient's own policies then apply.
Full-detail reconstruction and volume measurement can be done by copying your captures to a Mac you control. That transfer happens over a cable or your own file sharing — not through any 123division server.
Your account and scan records are kept for as long as your account exists.
Removing the app from your phone deletes the local files but not the account; use Delete account first if you want everything gone. You may also email us and we will delete your account within 30 days.
123Hand is not directed at children under 13 and we do not knowingly create accounts for them.
If this policy changes we will update this page and the effective date above.
