1B Scan – Privacy policy
This policy covers 1B Scan for Android (com.onebytesystems.scan), made by 1Byte Systems. Last updated: 20 October 2026.
Summary
1B Scan has no Internet permission: it cannot send anything to us or to anyone else. Your photos, documents and the text read from them are processed and kept only on your phone. We receive nothing from the app: no documents, no data about them, no account and no analytics.
What stays on your phone
- Scans: the photos you take or import, the processed pages and the PDF files you create are kept in the app's private storage. The original photo is kept so you can crop again or change the filter.
- Recognised text: the text is read on the phone by models that come inside the app, and kept with each page so you can search it. What you type in the search never leaves the phone.
- Signatures and stamps: the signature and initials you save, and the dates, texts, highlights and covered areas you add, are kept in the app's private storage.
- Settings, folders and the trash: kept in the app. Documents in the trash are deleted for good after 30 days, and everything is deleted when you uninstall the app.
Sharing, saving and printing
- Sharing uses Android's share menu: a document goes only to the app you choose, which handles it under its own policy. The files made for sharing are temporary and are deleted with the document and when the app restarts.
- Covered areas are erased from the image and from the text layer of what you share or save.
- Saving a copy writes the file in the folder you choose with Android's file picker. Printing uses Android's print service and the printer you choose.
- Importing uses Android's photo picker or file picker: the app only sees the items you choose.
- Links in QR codes are opened in your browser only when you tap Open link.
Camera
The camera is used only to scan: the preview finds the edges of the page and the photo is taken on the phone. Nothing is recorded or sent. Without the camera permission you can still import images and PDF files.
Purchases
Version 1.0 has nothing to buy. A later version will offer an optional Pro purchase through Google Play: Google Play handles the payment under its own terms and only tells the app that the purchase exists. We do not receive your payment details.
What we do not do
- No ads, no analytics, no crash reporting services, no tracking and no third-party SDKs that use the network.
- No account and no cookies. Nothing is sold or shared with anyone.
- We do not run any server for 1B Scan, so we hold no data about you to keep, share or delete.
Permissions
- Camera: to scan documents.
- No Internet, no storage, no location, no contacts and no microphone permission.
Your rights and contact
As we receive no personal data from 1B Scan, there is nothing for us to access, correct or delete: everything is on your phone, and you can delete it in the app or by uninstalling it. For any question, write to 1bytesystems@gmail.com. The privacy policy of 1Byte Systems also applies.
Changes
If 1B Scan ever needs to handle data differently, we will update this page, and its date, before that version is published.
