Scan a document. It never leaves your device. No cloud. No account. No export fees. Point the camera and ScanOnce finds the edges, straightens the page and captures it clean. Available in English, Spanish, French, German, Arabic, Russian, Hindi, Ukrainian, Korean, Portuguese, Chinese, Japanese and Indonesian. WHY SCANONCE Most scanner apps ask for a monthly fee to export a PDF, and quietly upload your documents to someone else's server on the way. Your lease, your tax return, your medical card. ScanOnce does neither. Exporting is free, and nothing you scan ever touches the internet. WHAT IT DOES Sharp, automatic captures Point the camera at a page. Edges are detected, perspective is corrected, and multi-page documents are captured in one go. Find any document by what is written inside it Text is recognized directly on your device, so you can search for a word you remember and land on the right page. No upload, no waiting. Export the way you need Share as PDF, export single pages as JPEG, or send straight to a printer. Tidy it up Rotate, crop, and switch between colour, greyscale and high-contrast black and white. Reorder pages by dragging. Rename and file into folders. Locked if you want it locked Turn on Face ID and your documents stay sealed behind it. PRIVACY, PLAINLY ScanOnce makes no internet connections at all. There is no account to create, no analytics, no advertising, and no third party receiving anything.
