Privacy-first Chrome extension for inspecting, stripping, and SNS-optimizing image EXIF metadata — fully client-side.
Photo EXIF Util processes all images entirely on your device. No image data, metadata, or personal information is ever transmitted to any server.
| Data Type | Storage | Transmission |
|---|---|---|
| Image files | In-memory only, never persisted | Never |
| EXIF metadata | In-memory only | Never |
| User preferences | chrome.storage.local (your device only) |
Never |
This extension declares host_permissions: ["*://*/*"] (http and https URLs).
Justification: This permission is required to fetch image bytes from user-supplied URLs (typed manually or selected via the right-click context menu) so that EXIF analysis can be performed locally in the browser. Manifest V3 enforces CORS on Background Service Worker fetch calls unless the extension holds host permissions for the target origin, which is why this permission is required (not optional).
The permission is used only:
It is never used for passive monitoring, tracking, or any background network activity. All fetches happen through the Background Service Worker; content scripts never receive this permission.
Users who only need to analyze locally uploaded files (drag-and-drop or file picker) are not affected by this permission — local file processing does not perform any network requests.
