Shrike
Stays on your Mac
Images and videos are processed on the device. There's no account, no server, no analytics, and no third-party code.
For Mac
Share the picture, not the details.
Shrike finds personal data in your images and videos and covers it up before you share them. Everything happens on your Mac. Nothing is uploaded, ever.
Coming soon to the Mac App Store
It knows what to look for.
Shrike reads the text in every frame and covers anything that matches its rules. Add your own for what only you know is sensitive.

Open, check, save.
Drop a file on the window, review your rules, and choose Shrike writes a redacted copy.
- Your own rules
- Add keywords or patterns for names, addresses, or anything else, and switch each one on or off.
- Every frame
- Matching text is covered with an opaque box in every frame of a video, not just the first.
- Text that moves
- Shrike can follow text across frames, so even half-typed or half-hidden text gets covered.
Private by design, not by promise.
Images and videos
Open a screenshot, a photo of a document, or a screen recording. Shrike saves a redacted copy and leaves the original untouched.
Rules that follow you
Custom rules sync between your devices through iCloud Keychain, end-to-end encrypted. Not even the developer can read them.

Privacy Policy
How the Shrike app handles your data.
Last updated 18 October 2026
No data collected
Shrike does not collect, store, or share any of your data, and it does not track you. There are no analytics, no advertising, and no third-party code in the app. Every image and video you open is processed entirely on your device and is never uploaded anywhere.
Custom rules and iCloud Keychain
If iCloud Keychain is turned on, your custom redaction rules sync between your devices through it. This sync is end-to-end encrypted by Apple, so the developer cannot read your rules.
Contacting support
If you email support, the developer receives your email address and whatever you include in your message. They are used only to reply to you.
Apple
Apple may share crash reports and usage data with the developer, but only if you have opted in to sharing them in your device's settings. This data is handled under Apple's Privacy Policy.
Changes and questions
Any changes to this policy will be published on this page. For questions about privacy, write to shrike@eigenein.dev.
