Sotto - Privacy Mask

【Privacy-First: Complete Local Processing】
All image processing is performed entirely on your device. No image data is ever sent to external servers.
Sotto is a privacy-focused tool for everyday tasks like masking personal information before posting screenshots on social media, extracting text from business cards and documents, or resizing images.

Main Features

■ Text-Based Masking
Automatically detect and mask sensitive information such as names, phone numbers, addresses, and email addresses.
Instead of manually painting over content, Sotto uses clean block-style masks to help organize screenshots in a more readable way.

■ OCR (Text Recognition) + Smart Actions
Extract text from images, supporting both horizontal and vertical text.
Tap extracted addresses or phone numbers to instantly open maps or make calls.
Smart Actions make it easy to use information from business cards and documents right away.

■ Text Correction Tool
Includes a correction tool for cleaning up text extracted by OCR.
Easily format text within the app, such as organizing unnecessary line breaks.

■ Multi-Function QR Code Reader
Read QR codes not only via camera, but also from images in the Photos app.
Supports opening URLs, making phone calls, and reading eSIM QR codes.

■ Image Adjustment (Resolution, Cropping & Watermark)
Change just the resolution (dimensions) of an image in pixels — handy for resizing App Store screenshots to required sizes.
Choose your finishing method from "Crop to area," "Fit entire image to size," or "Fit within margins" to adjust images to your needs.
You can also add a watermark to images, with adjustable position and shadow — great for deterring unauthorized reuse or displaying your brand.
