Content Scripts
The Extension includes content scripts that run on:

These scripts only interact with the page to:

- Complete Control: All data remains on your device - you can delete it at any time by clearing the Extension's data or uninstalling the Extension
Data Security
We implement appropriate technical measures to protect your information:
- All data is stored locally in Chrome's secure storage system
- No data is transmitted over the network, reducing security risks
- Your data remains on your device and is not accessible to us or third parties
However, no method of storage is 100% secure. While we strive to protect your data, we cannot guarantee absolute security. We recommend that you take appropriate measures to secure your device.

Your continued use of the Extension after changes become effective constitutes acceptance of the updated Privacy Policy.
