Cookies & Local Storage Policy.
Check Mouse DPI is committed to total privacy and data minimization. Understand how our browser-native testing suite handles cookies and client-side storage.
1. What Are Cookies and Local Storage?
Cookies and local browser storage (such as localStorage) are small data files or key-value entries stored directly inside your browser session. They enable web applications to remember your interface preferences, test baselines, and language selections between visits.
2. How We Use Storage Mechanisms
Check Mouse DPI operates as a 100% client-side precision measurement suite. We utilize localStorage exclusively for essential functional purposes: saving your Cookie Consent acceptance, preserving your selected distance units (cm/inches), and keeping your chosen language active. We never use storage to build user profiles or track cross-site activity.
Client-Side Storage Inventory
| Key Name | Type | Purpose | Duration |
|---|---|---|---|
| cmdpi_cookie_consent | Essential | Saves acceptance of cookie & storage banner | Persistent (localStorage) |
| cmdpi_unit_preference | Functional | Remembers selected ruler travel units (cm / inches) | Persistent (localStorage) |
| cmdpi_dpi_target | Functional | Preserves target DPI benchmark selection | Persistent (localStorage) |
3. Zero Telemetry & Tracking
Unlike invasive web utilities or third-party ad networks, our measurement algorithms process all mouse travel coordinates, velocity vectors, and counts per inch locally in your browser sandbox. No cursor coordinates or personal identifying tokens are ever transmitted to remote analytics servers.
4. Managing and Clearing Your Preferences
You have complete control over stored browser data. You can inspect, modify, or clear your localStorage and cookies at any time through your browser's Developer Tools or Privacy Settings. Clearing your browser data will reset your saved preferences and display the consent banner upon your next visit.
