Privacy Policy

Last updated: June 8, 2026

This policy explains what data Stdle collects, why, and the choices you have. We kept it plain-English. It pairs with our Terms of Service.

1. Who we are

Stdle is a free daily code puzzle game for developers, operated by an individual ("we", "us", "the operator"). This policy applies to stdle.com and the Stdle service. We are the data controller for the personal data described below.

2. There are no accounts — play is entirely local

Stdle has no sign-in, no accounts, and no player database. We never ask for your email or name and we have no way to identify you. Your theme preference and game progress (stats, streaks, guess history) are stored only on your device in your browser's localStorage. They never leave your device.

3. Information we collect

No account or gameplay data. Because there is no sign-in and no player database, we do not collect or store your email, your name, a nickname, or your game results. Your stats and streaks exist only in your own browser.

Automatically-collected usage & device data. Like most sites, we and our analytics provider may receive standard technical data such as your IP address, browser and device type, operating system, referring pages, and how you interact with the service. This is used in aggregate to understand usage and keep the service running.

No payment data. Stdle is free. We do not collect or process any payment or financial information.

4. How we use your data

5. Legal bases for processing

Where the GDPR or similar laws apply, we rely on:

6. Cookies, storage & analytics

7. Third parties & sub-processors

We share data only with the service providers we need to run Stdle. They process data on our behalf under their own terms:

We do not sell your personal data, and we do not share it for cross-context behavioral advertising.

8. Data retention

We hold no account or gameplay data, so there is nothing of yours for us to retain. Your progress stays in your browser for as long as you keep it there. Aggregate, non-identifying analytics data is retained under our analytics provider's standard retention settings.

9. Your rights

Depending on where you live, including under the EU/UK GDPR and the Thailand Personal Data Protection Act (PDPA), you may have the right to:

To exercise any of these rights, email us at me@stdle.com. You also have the right to lodge a complaint with your local data protection authority.

10. Deleting your data

Your game progress lives entirely in your own browser, so you are in full control of it. Clearing your browser storage for stdle.com permanently removes your stats, streaks, and history from that device. There is no account for us to delete. If you have any question about data, email me@stdle.com.

11. Children

Stdle is not directed to children under 13 (or under 16 where a higher age of digital consent applies). We do not knowingly collect personal data from children. If you believe a child has provided us personal data, contact us and we will delete it.

12. Data security

We use reasonable technical and organizational measures to protect your data, including encrypted connections (HTTPS) and access controls at our hosting providers. No method of transmission or storage is 100% secure, so we cannot guarantee absolute security.

13. International data transfers

Our providers (Google and Vercel) may process data on servers located outside your country, including in the United States. Where required, such transfers are covered by appropriate safeguards such as Standard Contractual Clauses.

14. Changes to this policy

We may update this policy from time to time. When we make material changes, we will update the "Last updated" date above and, where appropriate, provide additional notice. Continued use of Stdle after changes take effect means you accept the updated policy.
