• Learning progress. When you are signed in, we store the items you mark as known and the sheets you favorite, so we can show your progress on your dashboard.
• Usage data. We collect anonymous usage data such as pages viewed, sheet view counts, browser type, and approximate location, to understand how the site is used and to improve it.
• Cookies. We use cookies to keep you signed in and to measure usage. See Cookies and analytics below.

How we use your information

• Remember your preferences, favorites, and learning progress.
• Measure and improve site performance and content.

Cookies and analytics

DevSheets uses a small number of cookies. Essential cookies keep you signed in during a session. For analytics, we use Google Analytics and Vercel Analytics to measure traffic and usage. Google Analytics may set cookies on your device. You can limit or block cookies through your browser settings, or opt out of Google Analytics using the tools Google provides.

Third-party services

• GitHub and Google, for sign-in.

Each of these providers processes data under its own privacy policy.

How we share information

We do not sell your personal information. We share data only with the service providers listed above, as needed to run DevSheets, or when required by law.

Data retention

We keep your account data and learning progress for as long as your account is active. If you ask us to delete your account, we remove your personal data and saved progress.

Your rights

You can request access to, correction of, or deletion of your personal data at any time. Depending on where you live, you may have additional rights under laws such as the GDPR or the CCPA. To make a request, contact us.

Data security

We use reasonable, industry-standard measures to protect your data. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

Children's privacy

DevSheets is not directed at children under 13, and we do not knowingly collect personal data from them.
