Specter Privacy Auditor is a Chrome extension that analyzes network requests made by your browser. This policy explains what data Specter accesses, how it is used, and what leaves your device.
Specter does not collect, transmit, or store any data on external servers. No data ever leaves your machine.
Specter accesses the following data locally:
All data is stored locally in your browser using IndexedDB. Sessions are retained according to your configured data retention setting (default: 30 days). You can delete individual sessions or all data at any time from the Settings page.
Specter optionally integrates with the VirusTotal API for domain reputation lookups. If you provide a VirusTotal API key in Settings, Specter will send domain names (never full URLs or paths) to VirusTotal’s API. This feature is disabled by default and entirely opt-in. VirusTotal’s privacy policy applies to those requests.
Specter’s ML classifier runs entirely locally using ONNX Runtime. No request data is sent to any external service for classification.
Specter requests the following Chrome permissions:
webRequest — to intercept and analyze network requestsstorage — to persist session data locallytabs — to associate requests with the correct tab and domainThese permissions are used exclusively for the features described above.
This policy may be updated occasionally. The latest version will always be available at this URL.
