Privacy

ChemWarden Learn keeps as little about you as possible.

• Reading the site needs no account and sets no tracking or advertising cookies. Your chosen level is stored in your own browser.
• Community accounts store your username, email address, a salted hash of your password (never the password itself), your confirmation that you are 13 or over, and what you post. Sign-in uses one essential cookie.
• Moderation: posts are checked by an automated safety classifier running on Cloudflare's infrastructure. They are not used to train AI models, and not shared with anyone else except where the law requires it.
• Deletion: you can delete your account from your account page. This removes your email and password hash and anonymises your posts.
• Payments for the optional supporter plan are handled entirely by Stripe. We never see your card details.
