Privacy notice

What we keep

• The student's mobile number and name, to sign in and to greet them.
• A parent's or guardian's mobile number, and when they agreed.
• Test answers, photos of answer sheets, marks, feedback and practice answers.
• Progress: XP, streaks, badges and which chapters have been taught at school.
• Network addresses for a short time, to stop people requesting too many sign-in codes.
• If notifications are turned on, the address the browser gives us for sending them. Signing out removes it.

What we use it for

• Running timed tests and marking them. Multiple-choice answers are marked automatically.
• Written answers are marked by an AI examiner, and teachers check the answers it isn't sure about or that a student asks to have re-checked. Photos of answer sheets are sent to the AI service only for marking.
• Suggesting what to practise next, from the student's own results.

We don't show ads, don't sell data, and don't track students across other apps or websites.

Who else sees it

• Teachers on LikhAnk who check marking see the answers but not the student's name: students write a paper code on their sheets instead. Each time a teacher opens an answer is recorded.
• Service providers that work for us: hosting and storage, the SMS service that sends codes, the AI service that marks written answers, and an error-reporting service. They may only use the data to provide that service, and may not use it to train their AI.
• The AI service is in the United States: photos of answer sheets, and the questions and marking scheme, are sent there for marking. The error-reporting service is in the European Union and receives technical details of errors only, never answers, names or phone numbers.

How long we keep it

• Photos of answer sheets, and the AI's reading of them (what it transcribed and its notes): 180 days after the test. Marks stay.
• Sign-in codes: until they're used, or a day after they expire.
• Records of code requests: 7 days.
• Accounts nobody has used for 2 years: deleted, with everything in them. We send an SMS a month before.
• Everything else: until the account is deleted.
• Backups: copies kept to recover from accidents are deleted on a rolling basis, within [backup period, to be set before launch], and are never used for anything else.

Your choices

• See and change the name and mobile number in Account.
• Delete the account in Account → Delete my account. This removes the student's answers, photos, marks, progress and sign-in records straight away, including the parent's number.
• A parent can ask us to delete their child's account or stop using their data at any time.
