Privacy Policy

Last updated: July 6, 2026

Codestroke ("we", "us", the "Service") is a free typing speed test for developers, available at codestroke.dev. This Privacy Policy explains what information we collect, how we use it, and the choices you have. By using Codestroke, you agree to this policy.

1. Information we collect

• Account information. If you create an account, we store your username and email address. If you sign in with Google, we receive your name and email address from Google to create and identify your account.
• Typing test results. When you complete a test, we store performance data such as CPM (characters per minute), WPM, accuracy, the language practiced, test duration, and timestamps.
• Local device storage. If you use Codestroke as a guest, your recent results and preferences (theme, settings) are kept in your browser's local storage on your device — not on our servers — until you clear them or create an account.

We do not collect payment information, and Codestroke is completely free to use.

2. How we use your information

• To create and secure your account and let you sign in.
• To calculate and display your statistics, history, and progress.
• To send account-related emails (for example, email confirmation).
• To maintain, protect, and improve the Service.

We do not sell your personal information.

3. Third-party services

We rely on a small number of trusted providers to run Codestroke:

These providers process data on our behalf under their own privacy policies.

4. Cookies and local storage

Codestroke uses your browser's local storage to remember your settings and guest progress, and Supabase uses secure storage to keep you signed in. We do not use third-party advertising or tracking cookies.

5. Data retention and deletion

We keep your account data for as long as your account exists. You are in control:

• You can clear your logs and statistics from your profile at any time.
• You can permanently delete your account from your profile page. Deleting your account removes your profile, session history, and statistics from our database.

6. Children's privacy

Codestroke is not directed to children under 13, and we do not knowingly collect personal information from them.

7. Changes to this policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated date above.

8. Contact

If you have any questions about this policy or your data, contact us at yuoibur@gmail.com.
