Are my scanned documents uploaded to any external server?
No, absolutely not.

Your private contracts, bank statements, and IDs never leave your phone.
Which Android devices and versions are supported?
FastDocscan supports all Android smartphones running Android 7.0 (Nougat, API 24) and above, all the way through to Android 15 (API 35). It is optimized for both budget devices and flagship smartphones from Samsung, OnePlus, Xiaomi, Google Pixel, Realme, Vivo, and Motorola.
Can I add my signature and custom watermarks to scanned PDFs?
Yes! FastDocscan includes a built-in digital signature tool where you can draw your signature using your finger or stylus and place it exactly where needed on the document. You can also add custom watermarks (e.g., "CONFIDENTIAL", company names, or dates) to protect your files before exporting.
