A four-fold safeguard mechanism for enterprise-grade privacy protection

For lawyers, doctors and other users who require high document sensitivity, Fenn provides the following privacy control solutions:

Sandbox Mode Configuration::
- Enable the "Index encrypted files only" feature in the security settings
- Create encrypted dmg files via macOS disk utility
- Limit the Fenn index range to this encrypted container
<strong]Dynamic exclusion rules: Add in Settings → Privacy Protection:
- Path blacklisting (e.g. /Confidential/)
- File name regular expression (e.g. *contract*.docx)
- Automatic skipping of documents containing specific metadata (e.g. author=Law Department)
Trace Removal Program: Regular implementation:
1. Shift+Command+Delete to clear search history
2. Execute "defaults delete com.fennapp RecentSearches" in the terminal.
3. Enable the "Automatically clear preview cache on reboot" option
<strong]Physical isolation program: For core classified scenarios, it is recommended:
- Using an external SSD to store sensitive files
- Mounts and manually triggers indexes only when needed
- Set access rights with "sudo chmod 000 /Volumes/Secret".

The program has been tested to meet the basic requirements of the HIPAA medical privacy standards.
