Worksheet Cleaner turns a photo of your worksheet into a clean blank original — ready to print, practice, or solve again. HOW IT WORKS 1. Photograph the sheet, scan it, or import a PDF 2. The app crops the sheet automatically 3. Tap "Clean" 4. View the result, save, print, or export as PDF THE SHEET STAYS THE ORIGINAL • No generative AI image model. The sheet is never redrawn — printed text, lines, boxes and illustrations stay pixel-for-pixel intact. That is exactly what redraw-style apps cannot do. • Every pen colour is detected, not just pencil: ballpoint, felt tip, marker. • Export the result as PDF, print it, share it, or keep it in the archive. HOW DETECTION WORKS • To find the handwritten areas, the app sends a downscaled copy of the sheet to our server. Only coordinates come back — no text, no edited image. • The removal itself runs on your device. • The copy is not stored; we do not pass it on for AI training. • Cleaning therefore needs an internet connection. Viewing, printing and exporting sheets you already cleaned works offline. EXTRAS • Multi-page scan into one document • Subject auto-detection from worksheet content • Textbook recognition via ISBN scan • Student profiles (multiple kids, separate histories) • Choose where files are stored: on the device or in any folder you pick, including iCloud Drive • Spotlight search across all saved documents • iPhone, iPad, and Apple-Silicon Mac PRIVACY • No login, no account, no ads, no tracking • Cleaned sheets and student profiles stay on your device or in the folder you picked yourself • Only the downscaled image copy is transmitted, for detection — no name, no account, no advertising ID • Full privacy policy in the app and at https://www.worksheet-cleaner.com/legal/cleaner-datenschutz.html SUBSCRIPTION • 2 free pages within a 5-day window per installation • Then Premium: up to 100 pages per month on the monthly plan, up to 300 pages per month on the yearly plan (fair use) • Apple shows the current local price before purchase • If Apple shows an introductory offer, it is available once per Apple ID • Auto-renews, cancel anytime via your Apple ID • Required Apple disclosures at the bottom of this description PLEASE NOTE Detection can miss handwritten areas or mark too much. Look at the result before you rely on it. SUBSCRIPTION — REQUIRED DISCLOSURES Worksheet Cleaner Premium is an auto-renewable subscription. Payment is charged to your Apple ID.
