Privacy Policy for Acne-Safe Ingredient Checker
Last updated: January 3, 2025
Introduction
Acne-Safe Ingredient Checker ("we," "our," or "the extension") is committed to protecting your privacy. This Privacy Policy explains how our Chrome extension handles information when you use it.
Data Collection and Storage
We do NOT collect, transmit, or store any personal data on external servers.
All functionality of this extension operates entirely on your local device. No data leaves your browser.
Local Storage
The extension uses Chrome's local storage API (chrome.storage.local) for optional performance caching. This storage:
- Is stored ONLY on your device
- Is NEVER transmitted to any server
- Is NEVER synced across devices
- Is NEVER shared with third parties
- Can be deleted at any time by uninstalling the extension or clearing browser data
Note: The current version of the extension uses a hardcoded ingredient database and does not require storage. The storage permission enables future enhancements and is used only for optional local caching.
