1. Commitment to User Privacy

At DoubleClickTesting.com ("Double Click Tester", "we", "our", or "us"), we prioritize privacy by design. Our hardware mouse switch diagnostic tool is engineered to run client-side inside your browser without harvesting personal identifiers, keylogs, or sensitive device tracking.

2. Data We Do NOT Collect

We do not collect or store any of the following:

• No Personal Identifiable Information (PII): We do not ask for names, email addresses, phone numbers, or account registrations to use the diagnostic tester.
• No Keystroke or Input Logging: Click event listener timing is evaluated locally in memory using browser API performance.now(). Mouse click intervals are never transmitted to external servers.
• No Third-Party Data Selling: We do not broker, rent, or sell user diagnostic logs or usage metadata to advertisers or data aggregators.

3. Local Storage Usage

We utilize browser localStorage exclusively for client-side user experience preferences:

• theme: Stores your preference for Dark Mode or Light Mode.
• lang: Stores your language selection preference.
• threshold: Stores your preferred failure threshold in milliseconds (e.g. 80ms or 50ms).

This data stays 100% on your device and can be cleared at any time by clearing your browser cache.

4. Server Logs & Security

Like standard web servers, our hosting provider may collect standard non-identifying technical server logs (such as IP address, browser user-agent, and HTTP request time) solely for network security, DDoS protection, and server uptime monitoring.
