How can we help?
Email hw@mathsretriever.com and a real person will reply. Including your iPad model and the app version (shown in the app’s settings) speeds things up.
Please don’t send pages of student work in a first email — describe the problem and we’ll ask for what we need.
Frequently asked questions
Which devices does Maths Retriever run on?
Maths Retriever runs on iPad (iPadOS 17 or later) and on iPhone, where you photograph your paper working instead of writing on screen. On iPad, Apple Pencil is optional — turn off “Pencil only” in the pen tools to write with your finger. Marking, hints and retrieving questions need an internet connection.
Do I need an account?
No. There is no registration, log-in, or email address anywhere in the app. Your iPad is identified anonymously using Apple’s App Attest, and your saved work stays on the device.
How does the marking work?
When you tap Check, the app photographs the page, reads your handwriting, and marks it line by line in red ink drawn over your own writing — with the correction written beside the step that went wrong. Like any marker, it can occasionally misread a page; if a marking looks wrong, take another look at the flagged line and tell us via the in-app feedback option so we can look into it.
What does the free tier include?
A starter set of questions in every topic, 5 marked checks and 10 hints a day, the answer with key working for every part, the mistake-log summary, the review deck, and a predicted grade. The daily counts reset each day. See Pricing for what Pro adds.
How do I manage or cancel my subscription?
Subscriptions are handled entirely by Apple. To manage or cancel, open Settings on your iPad, tap your name, then Subscriptions — or open the App Store app and tap your profile picture. Cancelling stops the next renewal; you keep Pro until the end of the period you paid for.
I bought Pro but the app says I’m on the free tier.
Open the upgrade screen in the app and tap Restore purchases. Make sure the iPad is signed in to the same Apple ID that bought the subscription. If it still doesn’t appear, email us and we’ll sort it out.
How do I get a refund?
Apple handles all payments and refunds. Visit reportaproblem.apple.com, sign in with your Apple ID, and choose the purchase.
How do I delete my data?
Your work lives on your iPad. Use Erase all saved work in the app’s settings to delete the local copy, or simply delete the app. There is no named account — the service keeps only an anonymous record (your subscription link and usage counters) to run the AI features, and Delete my data in the app’s settings removes it. Handwriting and questions are not stored on the servers beyond a briefly buffered marking result — see the privacy policy for the full picture.
Found a wrong answer or a question that doesn’t look right? Use the feedback option in the app — it sends the question reference along with your message, anonymously.
