Camera, Gallery, and Uploaded Images

The Application may allow Users to use their Device camera or photo gallery to upload or scan an exercise written on paper, such as a mathematics exercise completed in a notebook or on draft paper.

This feature is optional. It is intended to help Users request immediate feedback or correction without manually typing the exercise.

When You use this feature, the image may be processed only for the purpose of reading, analyzing, correcting, or providing feedback on the submitted exercise.

Images uploaded through the camera or gallery are processed temporarily to provide the requested educational feedback or correction. They are not stored permanently in the user profile or as part of a personal student record.

We do not store these photos permanently as part of a personal student record. Images submitted through the camera or gallery are used only to provide the requested educational feedback and are deleted or not retained after processing, unless temporary technical retention is necessary for security, debugging, error handling, or legal compliance.

You can enable or disable camera and photo gallery permissions at any time through Your Device settings.

User-Generated Educational Content

The Application may allow Users to type or submit mathematics exercises, questions, answers, or other educational content in order to receive explanations, corrections, or AI-assisted feedback.

This feature is optional. The submitted content is processed only for the purpose of providing the requested educational feedback, correction, or explanation.

We do not store these texts, answers, or submitted exercises permanently as part of a personal student record. They are used to provide the requested response and are deleted or not retained after processing, unless temporary technical retention is necessary for security, debugging, error handling, abuse prevention, or legal compliance.

Transfer of Your Personal Data

Your information, including Personal Data, may be processed at the Company's operating offices and in other places where Service Providers are located.
