This app has no account system. Nothing about you, and nothing about how you play, leaves your device. There is no sign-in, no profile held on a server, no advertising and no analytics. The rest of this page explains exactly what that means, field by field.

The app asks for the camera and your photo library for three things, all optional, and it works fully without any of them:
Every picture is measured on the device itself and written into the app's own container as a JPEG. None of them is uploaded, shared, or read by anyone else. The one thing the app ever writes out is a specimen card, and only when you tap Save Card to Photos yourself.
On the very first launch, and only then, the app asks its own endpoint whether there is a notice to display. That request carries no identifier of any kind — no name, no device id, no advertising id, nothing that could identify you or your device. It is never repeated on later launches.
There is no other network traffic. No leaderboard call, no telemetry, no advertising request, no third-party SDK reporting on your behalf.
Nothing personal is collected, so there is nothing to sell, share, or hand on. No data broker, no advertising network and no analytics provider receives anything from this app, and no data is used to track you across other apps or websites.
The app is rated 4+. There is no chat, no user-generated content that anyone else can see, no social features, no purchases and no advertising. Nothing personal is collected from anyone, regardless of age.
Open Settings → Erase All Progress inside the app. That removes every save file and every stored picture from the device immediately. Deleting the app removes its container entirely and has the same effect. Because nothing is held anywhere else, there is nothing further to request or erase.
Rights of access, correction, portability and erasure apply to personal data held about you. This app holds none: everything it stores stays on your device, under your own control, and is removed with the app. If you believe otherwise, write to us and we will look into it.
If this policy changes, the revised version will be posted at this address with a new date below.
Questions about this policy or about the app can be sent through the support page. That form is part of this website, not part of the app: what you type into it — your email address, the reason you chose and your message — is sent to us so that we can answer you, is used for nothing else, is never passed to an advertiser or a data broker, and is deleted once the matter is settled. Writing to us is entirely your choice.
