Private by design

Your documents never leave your phone

Scanning, text recognition, PDF editing and password protection all run on your device. Scandra stores everything in private app storage and never uploads your scans, your extracted text or your signatures — the things you scan tend to be contracts, IDs and bank forms, so that matters more here than almost anywhere.

Nothing uploadedNo cloud sync, and no server to sync to.
No accountNothing to sign up for, nothing to sign in to.
Locked if you wantOpen the app behind a fingerprint or PIN.
AES on your PDFsPassword protection applied on the device itself.

What the app does and does not collect is in the privacy policy.

Pricing

Free, and no subscription.

Unlimited scans, unlimited pages, and text recognition included rather than sold as an add-on. Every export is clean — there is no watermark on any of them.

  • Free — no account, no sign-up, no subscription
  • No watermark, ever, on any export
  • Ads support the free version; a one-time purchase removes them

Getting your documents out is never restricted — export to PDF, JPEG or TXT, and share them wherever you like.

Questions

Scandra — frequently asked

Does Scandra put a watermark on my scans?

No, never — on any export. Most scanner apps stamp free exports or lock basic tools behind a subscription. Scandra has unlimited scans, unlimited pages, and free text recognition rather than a paid add-on.

Does Scandra work offline?

Yes. Scanning, edge detection, text recognition, PDF merging, splitting, compression and password protection all run on your phone. There is no account and no server that could receive your documents.

Can I search inside my scans?

Yes. Scandra reads the text in each scan and stores it locally, so you can search for a word and find the document months later with no internet. You can also copy the text, export it as TXT, or save a searchable PDF.

Which languages does the text recognition support?

Latin scripts including English, Spanish, French, German, Portuguese, Italian, Indonesian and Turkish, plus Devanagari for Hindi, Marathi and Nepali, and Chinese, Japanese and Korean.

Can I scan an ID card properly?

Yes. ID card mode puts the front and back on a single page at true physical size, so it prints exactly like the real card — useful for CNIC, driving licences, residence permits and student cards.
