Polar marker scans an answer-form locally. Only when the form is recognized as an answer-form, the code is sent to our servers to retrieve its lay-out. Only when you send over the scanned form, the image of the form is sent to our server.
When you send over the image, we store this image, the given answers and the corrections. For support, security and development reasons, wel also store your ip-address, your type of device, the version of your operating system and the version of the app you are using.
We do not access any other information other then described above. We do not access other images, do not access your location and do not look in your contacts. We even do not know your name or phone number. Just nothing.
