Privacy Policy

What we collect

• Account info: name, email, password (stored encrypted — we never see it in plain text)
• Practice data: answers, accuracy, mastery scores, dictation mistake entries
• Class info: if you join a tutor's class, that tutor can see your progress within that class
• Feedback you submit, plus optional contact details
• Usage analytics: we use Google Analytics to measure traffic (page views, rough region, device type — anonymised, aggregate) to understand usage and improve the product. This uses analytics cookies and does not include your name or practice content.

What we don't collect

No NRIC/ID numbers, home addresses, or payment/card details. We don't process any payments at this stage.

How we use it

Solely to provide the product — progress tracking, mastery scoring, mistake book, and tutor class management. We never sell your data to third parties or run third-party ad tracking.

Anonymised, aggregated data for research

We use de-identified, aggregated practice data for Chinese-language education research and product improvement — for example, accuracy and response time grouped by grade, question type, knowledge point and time period. This data contains no names, emails, login IDs or anything that identifies an individual, and cannot be traced back to a person. Findings may be published as reports or papers, or shared with education research partners, always as statistics and never as individual records; groups too small to be safely anonymous are not published.

If you would rather your child's practice data stay out of research aggregates, tell us via the contact below and we'll exclude the account. This does not affect normal use of the product.

Children & parental consent

AceLah is aimed at P1–P6 students, so most users are minors. Under Singapore's PDPA, children under 13 generally can't give valid consent on their own — a parent or guardian should consent and supervise use. We don't serve ads to children, don't build ad profiles, and never sell any user data; even with Google Analytics, ad personalisation and related signals are turned off. A parent/guardian can contact us any time to access, correct, or delete a child's account and data.

Storage & security

Data is stored with our cloud database provider (Turso) over encrypted connections. Passwords are stored hashed, never in plain text.

Practice reminder emails

If a child's account has a parent email, or was created by a parent account, we send the parent a short reminder after seven days without practice (or two weeks without dictation), at most once a week, plus the weekly report on Mondays. Reply to the email to stop them. These emails carry no marketing.

Data retention

We keep your account and practice data while your account is active, to provide the service. When you delete your account or ask us to, we delete or anonymise your personal data within a reasonable time (except where the law requires us to keep it). Google Analytics keeps only anonymised, aggregate data on a short retention window.

Your rights

Under Singapore's Personal Data Protection Act (PDPA), you can contact us any time to access, correct, or delete your account and data.
