Security Mechanisms Explained
PromptHelper is designed with triple privacy protection:
1. Data storage strategy
- Pure local storage: all templates and settings are saved only in browser localStorage
- sandbox isolation: Scripts can only access storage created by themselves
2. Code security measures
- Open Source Audit: The full code is publicly available on GitHub, with community scrutiny
- least authority principle (LAP): Request only the necessary permissions to access the DOM elements of the target AI site
3. Transmission security
- No back-office services: Script running is done entirely on the client side
- Export encryption: Templates exported to local files instead of cloud storage
caveat::
- When sharing templates it is recommended to check if they contain sensitive information
- Remember to clear your browser data when using public computers
- Permissions can be further restricted through Tampermonkey's script quarantine feature
