Welcome to TypeDelta (typedelta.com). We respect your privacy and are committed to maintaining transparent data collection practices. This Privacy Policy details how we handle data across our speed tests, educational tutorials, browser certifications, and programmatic advertising services.

1. Information We Collect

Typing Performance & Telemetry: Words per minute (WPM), accuracy rates, error distribution per key, and test completion duration are calculated locally within your web browser. Telemetry is saved to your browser's `localStorage` to generate progression graphs.
Server Logs & Technical Data: When you access our website, our hosting infrastructure automatically logs standard technical information, including your IP address, browser user-agent, operating system, referring URL, and access timestamps.
Authentication Data: If you voluntarily sign in with Google 1-Click Sign-In, we store your public profile name, email, and avatar URL in Firebase Authentication to sync your speed certificates and high scores across devices.

2. Google AdSense & Third-Party Advertising (DART Cookies)

We partner with third-party advertising companies, including Google AdSense, to serve advertisements when you visit our website.
