This extension does not collect, store, or transmit any personal data.

All text processing and highlighting are performed locally within the user's browser. The extension analyzes webpage content only to identify Chinese characters and apply color highlighting based on HSK levels.

No browsing history, personal information, or user activity is tracked or shared.

The extension uses Chrome's storage API solely to save user preferences such as selected colors and highlighted levels. This data remains on the user's device and is not transmitted to any external servers.
