Privacy policy
Last updated:
The short version
This site is built to need as little of your data as possible: no accounts, no sign-up, no advertising, no tracking cookies, and nothing stored on your device. You can use every lesson, widget, and practice set anonymously.
What we collect
We do not ask for, or store, any personal information. There are no user accounts and no forms that collect personal data.
Analytics
To understand which lessons help people, we use privacy-first, cookieless web analytics (Cloudflare Web Analytics). It reports aggregate numbers — page views, country, browser type — and does not use cookies, fingerprinting, or any identifier that follows you across sites. We cannot identify individual visitors from it.
Hosting
The site is served by Cloudflare. Like any web host, Cloudflare processes technical request data (such as IP addresses) transiently to deliver pages and protect the site from abuse. We do not receive or store that data ourselves.
Donations
Donations are handled entirely by a third-party platform (such as Ko-fi). If you donate, that platform’s own privacy policy applies; we never see your payment details.
Children
The site is designed to be safe for students of any age precisely because it collects no personal data from anyone — including children.
Changes
If the site ever needs to handle more data (for example, when paid tools launch), this policy will be updated first, and the date above will change.
