Sepia 写真編集 アプリ 向け Android 説明
Photos and screenshots say more than you think: where you were, what phone you own, sometimes a hidden copy of the uncropped shot or a video clip appended by motion-photo mode.
Sepia is the step before you hit send:
- X-ray: see everything the file says about you, ranked by severity. GPS in plain words, the hidden thumbnail shown, trailing data called out.
- Redact: ink and pixelation burned into the pixels, plus crop. Where the device supports code detection, QR codes are found and offered for covering.
- Prove it: the export is re-encoded from scratch, then Sepia re-opens its own output and shows you what is (and is not) still inside.
Everything happens on your device. This app has no INTERNET permission: the operating system will not let it open a connection, and you can check the manifest instead of trusting a promise.
Runs on Android 9 and newer, with Android System WebView 108 or newer. Android 9 has had no security fixes since January 2022, so on a phone that old Sepia works, but the phone itself is easier to break into.
