Privacy Policy
Last updated: December 31, 2025
Summary: FranzAI Bridge stores your API keys locally in Chrome's extension storage. We do not collect, transmit, or store any of your data on external servers.
What Data We Collect
FranzAI Bridge collects and stores the following data locally on your device only:
- API Keys: The API keys you enter (OpenAI, Anthropic, Google, Mistral, or custom keys) are stored in Chrome's extension storage.
- Configuration: Your settings including allowed origins, allowed destinations, and custom injection rules.
- Request Logs: A temporary log of recent requests (up to 200 entries) is stored in memory for the request inspector. These logs are cleared when you close Chrome or click "Clear".
How We Use Your Data
- API Keys: Used solely to authenticate your requests to AI providers. Keys are injected into request headers by the extension and sent directly to the respective API endpoints.
- Configuration: Used to determine which pages can use the bridge and which APIs can be called.
- Request Logs: Displayed in the side panel for debugging purposes only.
Data Storage
All data is stored locally using Chrome's chrome.storage.local API. This means:
- Data is stored on your device only
- Data is not synced across devices (we do not use
chrome.storage.sync) - Data persists until you uninstall the extension or clear extension data
Data Transmission
FranzAI Bridge transmits data only in the following ways:
- To AI API providers: When you make a request through the bridge, your request data (including the injected API key) is sent directly to the API endpoint you specified.
- No analytics: We do not send any usage data, telemetry, or analytics to any server.
- No third parties: We do not share your data with any third parties.
Security
- API keys are stored in extension storage, which is not accessible to web pages or other extensions.
- The extension uses allowlists to control which pages can make requests and which APIs can be called.
- Requests are made directly from the extension to the API provider with no intermediary servers.
Your Rights
You have full control over your data:
- View: All stored data is visible in the extension's side panel.
- Delete: Use the "Reset All Settings" button to delete all stored data, or uninstall the extension.
- Export: Request logs can be exported as JSON from the side panel.
