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.
