Scan documents to searchable PDFs offline — one-time purchase, no cloud

Most scanner apps push a subscription and upload your documents to their cloud. For sensitive papers (IDs, contracts, receipts) that's the opposite of what you want.

What to look for in a scanner app

• OCR so scans become searchable PDFs.
• Everything on-device — no upload, no account.
• A lock (Face ID) for private documents.
• Offline, and a one-time price.

I built ScanTo Pro to do exactly that: scan → OCR → searchable PDF → Face ID lock, fully offline, pay once.

If you're comparing pay-once vs subscription tools generally, I keep a 5-year cost breakdown here → https://alice51849.github.io/ios-app-guide/subscription-swap.html
