BlurBox helps you protect screenshots and images before sharing. Text detection runs on device, so your images are not uploaded. BlurBox can detect text regions, suggest possible sensitive information, and let you choose which areas to blur. You stay in control: suggestions are for review, and BlurBox does not automatically hide content without your action. Features: • On-device text detection & OCR • Sensitive information suggestions • Tap detected text regions to blur them • Draw custom redaction boxes • Choose blur, pixelate, or black redaction styles • Review before saving or sharing • Free daily exports with "BlurBox" watermark • One-time Pro upgrade for unlimited exports without "BlurBox" watermark • Light Mode, Dark Mode, and system appearance support BlurBox is useful for hiding personal details such as contact information, account details, codes, addresses, or private messages before sending a screenshot to someone else. AI and text recognition results may be inaccurate. Always review the image before using or sharing the exported result. BlurBox exports an edited copy, and original metadata such as location, camera details, author, or copyright information may not be preserved.
