Privacy notice

Worksheets you submit

Only a parent or guardian can submit a worksheet. It is stored in private, encrypted storage in Singapore. Each file's type and contents are checked before it is kept, and photo metadata such as location is removed. Tuition Guru deletes worksheet images after 90 days. Records you create, such as your own corrections and notes, may be kept longer.

Photos your child takes inside a paper

While answering a paper, your child can take a photo of a handwritten answer, or of the pages of their paper booklet. Your child sees each photo and chooses “Use this photo” before it is saved. Each photo is checked for malware, its type and contents are checked, and location and other hidden details are removed before it is kept, in private storage in Singapore. You can see every photo, what the AI read and every mark once the paper is submitted. Photos are deleted after 90 days.

The AI reads these photos only if you switch on “AI may read your child's photos” for that child, in addition to the AI permission below. With it on, you do not approve each photo; one cleaned copy of each photo is sent at a time, and the AI may give your child one short, kind handwriting tip, never a score. If a photo cannot be read, your child is asked straight away to take it again.

Optional AI reading and marking

Where you choose AI processing, your child's answers (typed answers, photos of handwritten answers or of their paper booklet with location and other hidden details removed, and worksheet pages you upload and redact) are sent, with each question and its answer key or marking scheme where there is one, to Anthropic for processing outside Singapore, to read and mark your child's work. Under Anthropic's standard commercial API terms, inputs and outputs may be retained for up to 30 days, with limited exceptions for safety, misuse prevention and legal requirements. Anthropic states that commercial API content is not used for model training by default.

• It only happens if you give separate AI-processing permission for your child. You can refuse or withdraw at any time without losing features that do not use AI.
• For a worksheet page, you black out names, school details and other identifiers, and approve the redacted copy before anything is sent. This reduces what is shared, but cannot guarantee that every identifier is removed.
• Only one redacted page, or one part of a page, is sent at a time. Your original upload is never sent.
• Anthropic acts as our external AI processor. Processing happens outside Singapore, and we request processing on United States infrastructure.
• Zero data retention is not currently enabled. Anthropic states that it deletes inputs and outputs within 30 days. Content flagged for safety or misuse, or held for legal reasons, may be kept longer.
• We never submit your child's work to Anthropic in ratings or bug reports, and we do not use its file-storage or conversation features.
• The AI may mark answers against the question's marking scheme, or on its own judgement where there is no answer key. Only the question, its answer key or marking scheme and your child's answer or working are sent, never your child's name, school or account details.
• AI marks are final. You do not approve each mark: your child sees their marks as soon as marking finishes, and each AI mark says “Marked by AI”, or “Marked by AI without an answer key”. Where the AI is unsure, a second, independent AI checks the mark first, and your child gets the higher mark. You can question any mark in one line: it is re-checked automatically, you get a reply in plain words, and you can then ask a person at Tuition Guru to look, once. You cannot change a mark yourself.
• Without your AI permission no AI mark is given, and answers the answer key cannot mark wait. If you gave permission before 3 November 2026, when parents approved each AI mark, you are asked to give it again, because how marking works has changed.
• For a worksheet page you upload, what the AI reads is labelled AI-assisted and stays a draft until you check it. The AI is never used to diagnose, label or build a profile of your child, and it can be wrong.
• Your child never chats with the AI.

Manage this in AI worksheet processing settings.

AI help with our study guides

The Tuition Guru content team also uses AI to help draft study guides from our own material. No child's work, name or details are ever sent for this. A person on our team checks every guide and must approve it before any family sees it, and it is labelled when AI helped draft it.

Only our administrators can ask for a draft. This uses no personal data, so the AI-processing permission above does not apply to it and is not changed by it.

Erasing your data

A parent can erase one child's data, or the whole family account, from Account and data. You confirm it is you, by entering your password again or by following a link we email you. If you ask our support team instead, they raise the request and you still confirm it from the email we send you.

• Waiting period: after you confirm there is a waiting period (7 days unless we tell you otherwise when you confirm). You can cancel at any time until it ends.
• What is erased: the child's profile and login, answers, marks, uploaded images and PDFs, worksheets and transcripts, AI suggestions, retries and review sets, Study Studio progress, bookmarks and assignments, and anything else linked to them. Erasing the whole account also erases your profile, your assignments and your login, and frees your place in the beta.
• What is kept: a minimal consent record, deleted automatically after 24 months. It holds the consent notice versions and their fingerprints, a scrambled code in place of your account, the dates of the consents, withdrawals and the erasure, and nothing else: no name, no child's details and no work. Shared practice questions and study guides are not personal data and are not deleted.
• Anthropic: we keep nothing stored with Anthropic. Anything already sent for AI reading or marking may be kept by Anthropic for up to 30 days under its standard terms (longer only for safety, misuse or legal reasons). We cannot delete those copies sooner.
• Confirmation: your account page shows the request, its reference and its date. After a whole-account erasure you can no longer sign in, so keep the reference shown when you confirm.

Singapore personal data protection

Hoh Say Pte Ltd (UEN 201612411W) is responsible for the personal data in Tuition Guru. We aim to handle it in line with Singapore's Personal Data Protection Act. We hold no certification, accreditation or approval under the PDPA or any other scheme, and nothing here is legal advice.

• What we collect: your account details, the children you link to your account, the worksheets you submit, your own corrections and notes, and records of the permissions you give.
• Why: to run the service you asked for. We do not sell personal data, and we do not use it for advertising.
• Sending data overseas: if you turn on AI worksheet reading, the redacted page you approve is processed outside Singapore, as described above. We assessed that transfer before offering the feature. Everything else stays in our Singapore-region database and storage.
• Children: accounts for children are created and controlled by a parent or guardian, who confirms that relationship when they invite their child. Each child is linked to one parent account only; two parents in a family may share that one login. We do not ask children for personal details, and we do not ask anyone for identity documents.
• Keeping and deleting: worksheet images are deleted after 90 days. Other records are kept while your account is open, until you ask us to erase them (see Erasing your data).
• Your choices: you can withdraw AI permission at any time, you can ask us what we hold about you or ask us to correct it, and you can erase a child's data or your whole account yourself.
• If something goes wrong: we assess any personal-data breach and notify the PDPC and affected families where the law requires it.
