Gradeo is a bubble-sheet grader for teachers. It has no account, no backend server, no analytics and no advertising, and it makes no network connections.
Nothing. Class names, answer keys, student names you type in, and scanned results are stored only on your device. We never receive them.
Gradeo asks for camera access only to scan answer sheets. Each photo is analysed on your device to detect which bubbles are filled, and is then discarded: only the detected answers (letters) are saved. If you import photos instead, Gradeo reads only the photos you choose.
Student names are whatever you type. They stay on your device and are included in an export only when you choose to share a CSV or summary. If you share an export, the recipient is chosen by you through the iOS share sheet; we are not involved.
Delete a paper or a class inside the app, or delete the app to remove all of its data from your device.
Gradeo is a tool for teachers and is not directed to children. Students do not use the app.
