What We Collect

When you play DOL Daily, we record:

• Which sentence you played
• How many corrections you found
• Whether you solved it
• Your browser type and operating system
• The date you played

We do not collect your IP address, location, email, name, or any identifying information.

Why We Collect This

We use this data to understand which sentences are difficult, how well the game works, and whether people are enjoying it. We use it to improve DOL Daily.

How We Store It

Your game data is stored in a secure database (Supabase). Individual game records are deleted after 1 year. We keep aggregate statistics (total games played, total corrections made) forever.

Sharing Your Data

We don't share your data with anyone. We don't sell it, rent it, or give it to third parties. Period.

Cookies

We use localStorage to remember your streak (how many days in a row you've played). This is stored on your device only. We don't use tracking cookies.
