The part that matters most
Blacked out means gone.
Plumón never phones home. Nothing you capture, mark up, or redact leaves your Mac, not for a scan, not for a sync, not for anything.
On-device, always
Text recognition and automatic redaction use Apple's built-in text reading, right on your Mac. No server ever sees your screenshot.
No tracking
The app has no usage tracking, no hidden reports, and no accounts. Plumón doesn't know you exist.
Signed and notarized
Every build is signed with a Developer ID and notarized, so macOS opens it without a security warning. No unsigned installer, no workaround required.
No subscription
Free to download, free to keep. No trial clock, no login wall, ever.
How automatic redaction actually works
When you use Hide personal info, Plumón scans the current screenshot using Apple's built-in text reading, which runs on your Mac and never uploads the image. It looks for emails, phone numbers, street addresses (using Apple's built-in address detection, also on your Mac), Social Security-style numbers, and card- or account-style numbers, and proposes a box over each one it finds. Some addresses can be missed, and names are never auto-detected. Nothing is blacked out yet at this point.
You review the proposals: dismiss anything that was flagged by mistake, or click any text it missed (a name, a handle, an address it didn't recognize) to add your own box. Only when you confirm does Plumón turn every remaining box solid black, in one step. The scan, the proposal, and the redaction all happen on your Mac, start to finish.
Plumón deliberately does not try to auto-detect names, because name detectors are unreliable for names outside a narrow set of common English ones, and a missed name is a real privacy leak. Rather than give false confidence, Plumón asks you to add names yourself.
What "signed and notarized" means
Every copy of Plumón is signed with a Developer ID issued by Apple and submitted to Apple's notary service, so macOS opens it without a security warning. This is the same process legitimate, trustworthy Mac software goes through; it doesn't mean Apple reviewed what the app does, only that the specific file you downloaded matches what was submitted and hasn't been tampered with.
What this website collects (separate from the app)
The app itself collects nothing. This website, plumon.app, uses a privacy-focused, cookieless analytics service to see roughly how many people visit and which pages they read. It does not use cookies, does not track you across other sites, and does not collect any personal information; it only counts page views in aggregate. The only personal detail this site ever takes is an email address, and only if you type it into the optional update list (see Update emails below).
