Cookie Policy
Version 1.0 — Effective date: 28 July 2026
This policy explains the cookies and similar technologies used on ptwr.org and app.ptwr.org.
1. What cookies are
Cookies are small text files stored on your device by your browser. We also use browser local storage, which the app uses to save revision topics on your device so they work offline. Neither is used to track you across other websites.
2. Cookies and storage we use
Strictly necessary
These are essential for the Service to work — signing you in, keeping your session secure, and processing payments.
| Name | Provider | Purpose | Duration |
|---|---|---|---|
| Session cookie | PTWR | Keeps you signed in to your account | Session |
| __stripe_mid, __stripe_sid | Stripe | Payment processing and fraud prevention during checkout | 1 year / 30 min |
| __cf_bm, cf_clearance | Cloudflare | Security — protects the site against bots and attacks | Under 1 day |
Functional
| Name | Provider | Purpose | Duration |
|---|---|---|---|
| Local storage (offline topics, app preferences) | PTWR | Stores revision content and your settings on your device for offline use | Until you clear it or log out |
Analytics
We do not use any analytics or tracking tools on this website. Nothing is stored on your device to measure or profile how you use the site. That is why you will not see a cookie consent banner here — we have nothing to ask your consent for.
3. Managing cookies
You can delete or block cookies in your browser settings at any time; blocking strictly necessary cookies will stop the Service from working properly (for example, you will not be able to stay signed in). Clearing local storage removes offline topics from your device — they re-download when you next open a topic online.
