The app
A scanner app that works offline and never uploads
DafScan is a free document scanner app that does not upload your documents. It has no account and no server. Scans are stored on your phone, and the app works without an internet connection.
- Free
- No ads
- No account
The facts
- DafScan has no account. There is no email, password or profile.
- DafScan has no server. There is nowhere for a scan to be uploaded.
- Scans are stored in the app’s storage on your phone.
- A scan leaves your phone only when you share it.
- Scanning, filters and PDF export work offline.
- DafScan has no ads and no analytics.
- DafScan is free, with no subscription and no watermark.
What happens when you share
When you tap Share PDF, DafScan hands the file to the app you choose, such as Mail, Messages or Files. From there, that app’s rules apply. An email attachment goes through your mail provider. A file saved to iCloud Drive or Google Drive is uploaded to that account.
What the app can access
- The camera, to scan pages.
- The photos you pick, when you import pictures. It does not read the rest of your library.
- Nothing else. It does not ask for your contacts, location or microphone.
Check it yourself
- Turn on airplane mode.
- Scan a page in DafScan and save it.
- Open the document and share the PDF to Files.
Every step works, because none of them needs a connection.
What you give up
Scans live only on your phone, so there is no sync between devices and no DafScan copy to restore from. If you delete the app, its scans are deleted with it. Save the PDFs you need to keep to a place you trust. If you back up your whole phone to iCloud or Google, that backup is made by the phone and can include the app’s data.

Questions
Which scanner app does not upload my documents?
DafScan does not. It has no account and no server, so scans stay on your phone until you share them.
What is the safest way to scan documents?
Use a scanner that keeps the file on your device, and check where it goes when you send it. Before trusting an app with a passport or a contract, look at whether it needs an account and whether it stores scans in a cloud. DafScan does neither.
Does DafScan work offline?
Yes. Scanning, filters and PDF export run on the phone.
Does DafScan collect any data?
DafScan has no account, no analytics and no ads. Your scans are not sent to us or to anyone else.
What happens to my scans if I lose my phone?
They are lost with it, unless you saved copies or restore a backup of the whole phone. DafScan keeps no copy of its own.
