About

Priveo

Read full description

Priveo is a document scanner that works entirely on your device. And now it also cleans your photos and PDFs of the hidden data that reveals where, when and with what they were made. No account, no ads, no tracking and no servers: your files never leave your iPhone or iPad. This isn't a marketing promise. The app makes not a single network connection, so it has nowhere to send anything. SCAN • Multi-page scanner with automatic edge detection and perspective correction. • Add pages from the camera or from your photos. • Import a PDF you already have, or send photos and PDFs to Priveo from the Share sheet of any app. CLEAN YOUR PHOTOS AND PDFS • See what a file reveals before you share it: GPS location, phone and camera, date, author and the apps used. • If an image records that it was made with AI, which tool or which prompt, you'll see that too. • Choose what to remove with one checkbox per group, or remove everything. • JPEG, HEIC and PNG photos without recompression: the copy is pixel-identical. • PDFs too: author, apps, dates, comments and the location of the photos inside. • From Photos, without opening the app: Share → Remove metadata. • Every copy is analyzed again before it's handed over. Originals are never touched. RECOGNIZE TEXT • On-device text recognition in ten languages: Spanish, English, French, German, Italian, Portuguese, Russian, Japanese, Korean and Simplified Chinese. • Find any document by its content, not just its title. • Recognized text travels inside the PDF, so any reader can search and copy it. • Export the text as TXT or Word. SIGN AND ANNOTATE • Draw your signature with your finger and apply it to any page. Keep it protected to reuse it. • Add text, highlights and stamps on the page. • Cover what you don't want to show with a redaction, and burn it into the image permanently if you wish. ORGANIZE • Local library with search, folders and tags. • Duplicate, rename and archive documents so only what you use stays in view. • Merge several documents into one, or split pages into a new one. • Reorder and rotate pages, and adjust their look: original, grayscale or high contrast. • Designed for iPad too, with a sidebar and a cover grid. EXPORT • PDF, JPG images, TXT text and Word DOCX. • Choose the quality or set a maximum PDF size: handy when email won't accept large attachments. • Protect the PDF with a password. • PDFs created by Priveo don't carry your iOS version or their internal date. CONVERT • Turn a PDF into Word, text or images without uploading it anywhere. PRIVACY • Documents are stored only on this device, with iOS file protection. • They are excluded from backups. • If you delete the app, its documents are permanently deleted. • Optional Face ID lock. • The camera is used only for scanning, and Photos access is only for saving clean copies: Priveo can't see your photo library. Free, with no in-app purchases, and available in ten languages. Priveo does not collect, transmit or sell your documents or photos, and does not use them for advertising or tracking.
