We welcome contributions! The project is open source and available on GitHub. You can report issues, suggest features, or submit pull requests to help improve the tool.
Your privacy is extremely important to us. Here's how we handle your data:
We do not collect, store, or process any SQL code that you input into our formatter. All processing happens entirely in your browser, and your code never leaves your device.
We only use essential cookies to remember your preferences (like dark mode setting). We do not use tracking cookies or analytics services.
The only third-party services we use are Google AdSense for advertisements. These ads may use cookies for personalized advertising, but they have no access to your SQL code.
We may update our Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page.
