Maskduck

Maskduck is the fastest way to hide sensitive information in your screenshots and photos before you share them.

Smart detection finds private info for you — then a single tap covers it up. Everything happens on your device. Your photos never leave your phone.

WHAT IT MASKS • Phone numbers • Email addresses • Credit and debit card numbers • ID and document numbers • Bank account numbers • IP addresses • License plates • Long numeric strings that look private

HOW IT WORKS

1. Pick a photo from your library.
2. Maskduck scans the text and highlights anything sensitive.
3. Tap to hide it — or draw your own mask with the brush or rectangle tool.
4. Save or share. That's it.

FOUR MASK STYLES • Solid — clean black bars • Pixelate — classic mosaic look • Blur — soft gaussian blur • Hide — cover with a matching background

BUILT FOR PRIVACY • 100% on-device processing — nothing is uploaded • No account, no sign-in, no ads, no tracking • Works offline • Only asks for the photo permissions it actually needs

WHO IT'S FOR • Anyone sharing receipts, tickets, or order confirmations • Sellers posting product photos with personal info in the background • Developers and designers sharing screenshots with tokens or emails • Journalists and researchers redacting documents • Anyone who values privacy before hitting "send"

Stop cropping awkwardly or editing in five different apps. Maskduck handles it in seconds.
