Secure Watermark adds a lasting, visible watermark to ID documents and photos — entirely on your device. No network required, no account, nothing uploaded. Protection of privacy is the whole point: your images never leave your iPhone or iPad. THREE MODES ID Document Watermark Photograph both sides of a document and let the app handle the framing. Secure Watermark finds the card edge on device, corrects the perspective and crops it automatically, then lays the front and back out on a single A4 sheet ready for a full-page watermark. If the edges cannot be found, the shot is cropped to the on-screen guide instead. You can import existing pictures instead of shooting. Works with ID Card, Driver License, Social Security Card and Bank Card, and the finished sheet exports as an image or a PDF. Full-Screen Watermark Import several photos at once and cover each one with a watermark that spans the whole frame. Built for the moment a picture has to leave your hands: reduce exposure risk before it travels. Custom Watermark Pick one watermark from the library and place it where you want it, on a single photo or a whole batch. THREE WATERMARK TYPES • Text watermark — build a clean, professional mark with rich text. • Image watermark — use any image of your own as the watermark. • Signature watermark — write a handwritten signature and use it as the watermark. WATERMARK LIBRARY Every watermark keeps its own look, so choosing one applies it to every photo you export, and ready-made templates give you a starting point. Font, color, opacity, rotation, spacing, margins and alignment are adjustable, and you can save, rename or delete your own watermarks at any time. PRIVACY Everything runs on device. Secure Watermark makes no network requests and needs no sign-in, and your pictures are never uploaded anywhere. The photos you capture for ID document mode stay inside the app's own sandbox while you work; only the watermarked result you export is saved to your photo library. PRO Pro removes the export limits: • Export full screen watermark images • Export certificate images and PDFs • Export several images at once • View the preview full screen Custom Watermark mode exports without Pro, one image at a time. The other two modes need Pro to export. Built for iPhone and iPad, with an interface in 22 languages. Your documents, your device.
