Privacy Policy

Last updated November 13, 2026

We collect as little as we can, and we don't sell your data or show ads.

What we collect

• Account: your name, email address and a securely hashed password (we can't read your password).
• Gameplay: your puzzle results (time, accuracy), the name you sign challenges with, leagues you join, and custom chains you make.
• Device: an anonymous random ID in a cookie so your results work without an account, and, if you arrive through an invite link, a cookie that remembers who invited you. Your progress and streaks are also saved in your browser's local storage.
• Billing: payments are handled by Stripe. We never see or store your card number; we only keep a customer ID and your subscription status.

How we use it

To run the game, show leaderboards and challenge links, provide Pro features, process payments, prevent abuse, reward referrals, and reply to your support emails.

Who sees it

• Other players see your name and results on leaderboards, leagues and challenge links you share.
• Stripe processes payments under its own privacy policy. Our hosting provider stores our data for us.
• We don't sell your personal information. We may disclose it if the law requires.

Your choices

You can sign challenges with any name you like. To see, correct or delete your account and data, email chainleys.support@gmail.com. Deleting your account removes your profile; we may keep billing records as the law requires. You can clear cookies and local storage in your browser at any time, which resets your anonymous ID and saved streak.

Children

Chainleys isn't for children under 13, and we don't knowingly collect their information.

Security

Passwords are hashed, connections are encrypted, and access to our data is limited. No system is perfectly secure.
