Privacy

What we collect, and why.

MathsEdge is used by school students, so this is written to be read — not to be survived. Last updated 27 July 2026.

Who we are

MathsEdge is an independent product built and run in Melbourne, Australia. It is not operated by, affiliated with, or endorsed by any school. Contact: admin@mathsedge.net.

What the app collects

• Your account — email address, a display name if you set one, your year level and main subject. Passwords are stored only as an argon2id hash; we never see the original.
• Your work — the questions served to you, the handwriting you enter, its transcription, the marks and feedback, and any comment you leave on a question.
• Basic usage events — for example that a question was served or a result viewed, so we can tell which parts of the app are actually used.

What the marketing site collects

This site sets no cookies and runs no analytics. Fonts and formula rendering are served from this domain, so loading a page makes no request to any third party. If you send the contact form we receive the name, email address and message you type, plus the originating IP address for abuse prevention.

Handwriting and third parties

Handwriting recognition is performed by MyScript, so the strokes you write are sent to their service to be transcribed. Marking and feedback are produced by Anthropic's Claude models, which receive the question, your transcribed working, and — on questions involving a diagram, or where the transcription appears to have gone wrong — an image of your handwriting. Neither provider is given your name or email address.

What we never do

• We do not sell or rent personal information.
• We do not run advertising, or share data with advertisers.
• We do not use your work to train our own models.

Where it is stored

On a server in Australia, in a PostgreSQL database, with nightly backups held on separate storage. Traffic is encrypted in transit.

Students under 18

MathsEdge is intended for school-aged students, and we expect most users to be under 18. We collect the minimum needed to run the practice loop and we do not build advertising or behavioural profiles. If you are a parent, guardian or school and want to know what is held for a particular student, or want it removed, email us and we will action it.

Deleting your data

You can delete your account from My account inside the app, which removes your profile and your submitted work. Backups roll off on their normal cycle. You can also email us and ask.

Your rights

Under the Australian Privacy Act you can ask what personal information we hold about you, ask us to correct it, and complain if you think we have mishandled it. Email admin@mathsedge.net and we will respond within 30 days. If you are not satisfied you can escalate to the Office of the Australian Information Commissioner.

Changes

If this policy changes materially we will note it here and, where the change affects how your work is handled, tell account holders by email.
