FAQ
Are my photos uploaded anywhere?
No. Maskr processes everything on-device. The app makes zero network requests at runtime — there is no server, no analytics, no crash-reporting SDK, and no third-party tracking. Photos, OCR text, and barcode payloads never leave your iPhone or iPad.
Why does the app ask for camera and Photos access?
Camera access is only used when you tap “Take Photo.” The “Add to Photos” permission is only used when you tap “Save” to write the masked image back to your library. Maskr does not request read access to your photo library; importing uses the system picker, which hands the app only the photos you explicitly choose.
What does Maskr automatically detect?
Faces (front, profile, and small), text (OCR), QR codes, barcodes, and Chinese license plates — plus a sensitive-text rule engine that recognizes phone numbers, emails, ID numbers, bank-card numbers, passport / driver license numbers, addresses, recipient names, order and tracking numbers, payment numbers, contract and invoice numbers, company names, and door-plate / geo strings.
Auto-detection missed something. What can I do?
Open the manual editor: drag a rectangle, draw a freehand brush stroke, or use the row-mask tool to cover a whole line of text. Pinch to zoom up to 8× for precise work, and long-press any masked region to peek at the original underneath. Every action is undo-able.
Which mask styles are available?
Eight: black bar, white bar, mosaic, Gaussian blur, pixelate, solid color, translucent, and a custom-color option. Each style has its own intensity / corner-radius / expand-ratio sliders, and you can set per-category defaults in Settings.
Can the redaction be reversed?
No. The mask is irreversibly baked into the exported pixels. Anyone who receives the image — including us — cannot recover the original content from the redacted output. EXIF and GPS metadata are stripped on export by default.
How do I batch-process multiple photos?
Pick more than one image when importing — from Photos, the Files app, the clipboard, drag-and-drop on iPad, or the system Share Extension. Maskr applies your default style to each image, and a single tap saves or shares the entire batch.
How do I send a masked photo into another app?
From the result screen, tap Share to use the system share sheet (Messages, Mail, WhatsApp, etc.), Save to write to Photos, Save to Files for iCloud Drive or local destinations, Copy to put the image on the clipboard, or Export PDF for documents. The redaction is permanent in every export path.
Does Maskr work on iPad and with Apple Pencil?
Yes. Maskr is a Universal app. On iPad you can drag photos into the app from Photos or Files in Split View, and Apple Pencil works the way you expect for the freehand brush and eraser tools.
What are the system requirements?
iPhone or iPad running iOS 16.0 or later. Maskr is offered free with no in-app purchases, no ads, no subscriptions, no account, and no tracking.
How do I delete the data Maskr stores on my device?
The only data Maskr stores is your feature preferences (detection toggles, default mask style, export defaults, language). Deleting the app from your device removes all of it. You can also reset to defaults from Settings.
