Privacy Policy
Last updated: October 2026
What we collect
Free labs work without an account, and we do not ask for your name, email or any other personal details to use them.
Accounts and passes
If you sign in to buy a pass, we receive your email address from Google and keep a record of your orders so we can unlock the labs you paid for. We do not use your email for marketing.
Payments
Payments are processed by Stripe. We never see or store your card details; Stripe tells us only whether a payment succeeded.
Cookies
Signing in sets a cookie that keeps you signed in. A first-party cookie also remembers which website first sent you here, so we can tell which channels bring new teachers.
Server logs
Like most websites, our server records basic request information such as IP address, browser type and the pages visited. We use it only to keep the site running and secure.
Local storage
Some pages remember small preferences, such as a filter setting, in your own browser. This data never leaves your device.
Children
The site is designed for classroom use. Students can use the free labs without sharing any details about themselves; accounts and passes are meant for teachers.
Changes
If we change how we handle data, we will update this policy before the change takes effect.
