Privacy policy
Last updated 15 September 2026
The short version. Shadecard measures color on your phone. Your photos and saved recipes stay on the device unless you specifically ask for an AI analysis or turn on cloud backup. There is no advertising, no analytics SDK, and nothing is sold to anyone.
What stays on your device
Every measurement Shadecard makes — the captured frames, the CIELAB values, the matched shade and the recipe — is computed on your phone and stored in the app's own private storage. Your saved measurements and custom shades live in a file only this app can read. Uninstalling the app deletes them.
The camera
The app needs camera access to measure fabric. Frames are analysed in memory and are not written to your photo gallery, and the app does not read photos you already have.
What leaves your device, and only when you ask
- AI analysis. If you tap “Get AI analysis” on a result, the app sends that measurement's colour values and a small cropped image of the fabric to our server, which forwards it to the configured AI provider (such as Anthropic, OpenAI or Google) for a second opinion. The image and the result are kept in our request log so the accuracy of the system can be reviewed. If you never tap it, no image ever leaves the phone.
- Account. Creating an account stores your email address and a hashed password. Passwords are never stored in readable form.
- Cloud backup. If you back up your recipe book, the app uploads that document — your saved measurements and custom shades — to your account so you can restore it on another device. It is not shared with other users.
- Shade library. The app fetches the public shade library from our server at launch. That request carries no personal information.
What we never collect
No location, no contacts, no device identifiers for advertising, no third-party analytics or tracking SDKs. The app does not show ads.
Children
Shadecard is a tool for textile work and is not directed at children under 13.
Deleting your data
Uninstalling removes everything held on the device. To delete a cloud account and the backup attached to it, email the address below and it will be removed, along with any capture images logged from that account.
Changes
If this policy changes, the date at the top changes with it. Material changes will be announced in the app.
