Privacy notice
What we collect
No email address or contact detail is collected at this time. The quiz gives you its full result on screen with nothing to submit, and there is no sign-up form anywhere on the site. No name, no school, no child's name is requested at any point.
The only data collected is anonymous usage analytics, described below. If an email sign-up is added later, this page will be updated before it goes live and the section below on how long data is kept will apply to it.
Where your data is held
This site is hosted on Cloudflare Pages and served from Cloudflare's global network. The pages themselves are static files and contain nothing about you.
Analytics
We use PostHog (US region) to measure how the site is used — which pages are read, which links are followed, and roughly where visitors arrive from. It sets a cookie in your browser and records your IP address, from which an approximate city-level location is derived. Session recording is switched off in our configuration — nothing records what you see or type on screen — and we do not use it to build advertising profiles or sell or share what it collects.
If your browser sends a Do Not Track signal, or you block analytics scripts, the site works exactly the same — none of its content is gated on analytics.
How long we keep it
Analytics data is retained for 12 months and then discarded. If email sign-up is added later: an address would be kept for as long as you stay subscribed, and removed within 30 days of unsubscribing or asking to be deleted, apart from a minimal suppression record — the address alone — kept so we do not accidentally email you again.
We do not keep personal data indefinitely. Under the PDPA's retention limitation obligation we stop retaining it once it no longer serves the purpose it was collected for.
What we do not do
We do not sell, rent or share your address. We do not run advertising trackers on this site.
Access, correction and withdrawal
Write to [email protected] to see what we hold, correct it, or have it deleted.
Data Protection Officer
The PDPA requires every organisation in Singapore to appoint one. For MathsKid that is Christopher Chua, reachable at [email protected]. We aim to acknowledge within three business days.
