PrivyMark
100% on-device · nothing uploaded

Find private details
before you share

A screenshot holds more than you think — a phone number, a card, an address, a face in the background. PrivyMark finds them and covers them in one tap, entirely on your iPhone.

Hover the block to peek — that's the idea.

Private by architecture, not by promise

PrivyMark has no servers, no accounts and no analytics. There is nothing to leak, because nothing leaves.

Photos never leave

Scanning, covering and exporting all run on your device. Turn on Airplane Mode and everything still works.

Nothing is collected

No analytics, no ads SDK, no tracking, no crash logs with your content. The privacy label stays minimal because there's nothing to declare.

Nothing is kept

No history, no copies of your photos. Images handed over from the share sheet are deleted the moment they're read.

One tap from risky to ready

The same shots we ship to the App Store — swipe through the story: black bars are risks, green means covered.

Made for the moment before you hit send

From detection to cover styles to metadata, everything serves one flow: share safely.

Scans what matters

Faces, QR codes, emails, phone numbers, URLs, addresses, card-style numbers, ID numbers, order numbers and names.

Covers, your way

Solid block (irreversible, the default for text), pixelate, blur — plus a color well to match your style.

Hide Text

Blends a text region into the surrounding background so it simply disappears in place.

Text Explode

Long-press any line to fan it out into word chips — cover exactly the words that matter.

Marker & watermark

Freehand strokes for anything the scan missed, and a tiled custom watermark for photos you hand out.

Faces get emoji

Detected faces are covered with an emoji — tap to swap it, drag to reposition. Baked into pixels on export.

Metadata cleaned

See what's inside the file — GPS, device, timestamps. GPS is stripped by default; you choose the rest.

Right in the share sheet

Send a photo to PrivyMark from Photos, Messages or any app, cover it, and share back out.

Honest about the limits

A privacy tool that overpromises is a privacy risk. So we'll say it plainly:

Suggestions, not guarantees

Detection is a smart assistant, not a promise. Every match is a suggestion you review — always check before you share.

Blur can be reversed

Pixelation and blur on text can sometimes be undone. That's why text defaults to a solid, irreversible block.

Hidden watermarks: best-effort

The optional scrub clears simple pixel-level marks and all metadata. It cannot remove robust forensic watermarking.

Free. Actually free.

No subscription, no paywalled tools, no export badge, no account. Covering one photo safely should never be a premium feature.
