Cookie policy

crafyu_session

Keeps you signed in. HTTP-only (scripts can't read it), sent only over HTTPS and only to Crafyu.

Lasts: 7 days, or until you sign out

crafyu_oauth

Protects Google sign-in against forged requests while you're on Google's consent screen.

Lasts: 10 minutes, deleted after sign-in

Both are strictly necessary: without them you can't sign in. They are first-party (set by crafyu.com) and contain no personal information beyond a signed session reference.

These preferences are saved in your browser's local storage, not in cookies. They never leave your device and aren't used to identify you:

crafyu.theme

Remembers light, dark or system theme.

crafyu.accent

Remembers your accent colour, so the page doesn't flash teal before your settings load.

crafyu.sidebar.collapsed

Remembers whether the sidebar is collapsed.

crafyu.reader.contents, crafyu.reader.tutor

Remembers whether the lesson contents and tutor panels are open.

Clear them any time by clearing this site's data in your browser; Crafyu then uses its defaults.

• Google, when you sign in: the consent screen is on google.com and follows Google's cookie policy.
• Razorpay, when you upgrade: the payment window is served by Razorpay and may set its own cookies for security and fraud prevention, under Razorpay's policies.
• Wikimedia Commons, which serves some lesson images directly to your browser.

Crafyu's fonts and scripts are served from crafyu.com itself, so reading a lesson doesn't contact font or analytics services.

If we ever add a cookie that isn't strictly necessary (for example analytics), we'll update this page and ask for your consent first. Questions: hello@crafyu.com. See also the Privacy policy.
