4. Cookies, Local Storage, and Browser Data
We do not use cookies for tracking or advertising purposes. We may use essential cookies required for the Website to function properly (such as theme preferences), but these do not collect personal information.
Local Storage: We use browser localStorage to save your preferences (e.g., theme settings, reading preferences) and learning progress. This data stays on your device.
IndexedDB: The WebVM terminal uses IndexedDB to persist your Linux filesystem between sessions. This includes any files you create or commands you run. This data is stored entirely in your browser and can be cleared at any time through your browser settings.
Service Worker: Our Website uses a service worker to enable offline functionality and faster loading. The service worker caches static assets locally but does not collect or transmit any personal information.
5. Third-Party Services
Some of our tools may make requests to third-party APIs to provide functionality (e.g., IP geolocation, domain lookups). These requests are made directly from your browser and are subject to those third parties' privacy policies. We do not control or have access to the data processed by these services.
Our Website is hosted on Vercel. Please refer to Vercel's Privacy Policy for information about their data practices.
6. Data Security
We implement appropriate technical and organizational security measures to protect your personal information. However, no method of transmission over the Internet or electronic storage is 100% secure. While we strive to protect your information, we cannot guarantee absolute security.
