Privacy Policy
Last updated: 28 September 2026
1. The short version
PYmaths is built so that we cannot collect your personal data, even if we wanted to. There are no accounts, no logins, and no servers storing your tests. Everything you do — the papers you generate, the answers you mark, the results you see — happens inside your own browser.
2. What we store, and where
We store nothing about you on our servers. Your browser keeps two small records on your device so the app can do its job:
| Record | Purpose | How long it lives |
|---|---|---|
| Attempt snapshot | Lets you resume a test after a crash, reload, or closed tab — including an honest running timer | Until you submit or discard the test |
| Builder preferences | Remembers your topic, difficulty and mode selections so you don't re-pick them each visit | Until you change them or clear site data |
These records never leave your device. You can erase them at any time with the Discard button in the app, or by clearing site data in your browser settings.
3. What we do not collect
- No names, emails, phone numbers, or locations
- No analytics, heatmaps, or tracking pixels
- No advertising, and no data sharing or selling — there is nothing to share
- No uploaded content: your answers and results are never transmitted to us
4. Third-party services
To deliver the site we rely on three services. When your browser fetches fonts or files from them, they necessarily see standard request data such as your IP address, under their own privacy policies:
| Service | Role | Their policy |
|---|---|---|
| Cloudflare Pages | Hosts and delivers this website | cloudflare.com/privacypolicy |
| Google Fonts | Serves the typefaces used on this site | policies.google.com/privacy |
| jsDelivr | Serves the KaTeX library that renders mathematics | jsdelivr.com/privacy |
None of these services place marketing cookies on our behalf.
5. Cookies
PYmaths sets no cookies at all. For the full technical picture, including the browser storage we do use, see our Cookies & Storage Policy.
6. Children and students
PYmaths is an educational practice tool designed for students of all ages, including minors. Because we collect no personal data, there is no child data to protect, sell, or disclose. A parent or teacher can remove all traces of use at any time by clearing the browser's site data.
7. Your rights
Privacy laws such as the GDPR give you rights like access, correction, deletion, and portability. With PYmaths these are simple to exercise: your data exists only on your device, so deleting it is entirely under your control. If you have any question about this, contact us below and we will answer honestly and promptly.
8. Changes to this policy
If we ever add something that changes this picture — analytics, accounts, or anything else that touches personal data — we will update this page, change the "last updated" date, and ask for consent where the law requires it before switching it on.
