Privacy Policy

Last updated: October 7, 2026

This Privacy Policy describes how information is handled in Dokvio-PDF Scan & Doc Viewer ("Dokvio", "the app", "we"). Dokvio is built to work on your device first: your documents stay on your phone unless you choose to use an optional feature described below.

Summary

• Viewing, scanning, searching and organizing documents happens on your device. We do not upload your files to our own servers, and we do not have any.
• Optional Google Drive backup sends your documents only to your own Google Drive, and only if you turn it on.
• We collect anonymous usage statistics with Google Firebase Analytics (no file names, no document contents).
• We do not show advertisements and we do not sell your data.

Information Collection and Use

Most features of Dokvio (document scanning, reading PDF, Word, Excel, PowerPoint, text and ZIP files, search, folders, and document tools) operate entirely offline on your device. We do not collect, store, or transmit your local files or personal data to our own servers.

Camera Permission and File Access

The app requests camera access solely to let you scan physical documents. Files are opened through Android's system file picker or when you open or share a file with Dokvio, so you choose which files the app can read. We do not request broad storage permissions. These permissions are used exclusively for core app functionality.

Optional Google Drive Backup and Restore

If you choose to turn on backup, you sign in with your Google account and Dokvio copies your documents to a private folder in your own Google Drive, so you can restore them on a new phone or after reinstalling the app.

• Scope: Dokvio only uses the Google Drive drive.file permission. It can see and manage only the files and folders that Dokvio itself created. It cannot see any other file in your Drive.
• Where your data goes: directly from your device to your own Google Drive. We do not receive, store, or have access to your files, your Google account, or your Drive contents.
• Your Google account email is shown inside the app so you know which account is connected. It stays on your device.
• Deleting files: when you delete a document inside Dokvio, its backup copy is not deleted from your Drive. It is only marked as deleted and stays in your Drive until you remove it using "Clean deleted files from Drive" in the Backup screen (or delete it yourself in Google Drive). You can restore it at any time before then.
• Turning it off: you can disconnect backup at any time in the Backup screen, and you can remove Dokvio's access in your Google Account settings (Security, Third-party apps with account access). Files already in your Drive remain yours and can be deleted by you in Google Drive.

Dokvio's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.

Google Drive is a trademark of Google LLC. Dokvio is not affiliated with or endorsed by Google.

Usage Analytics (Google Firebase Analytics)

To understand how many people use the app and which features are useful, Dokvio uses Google Firebase Analytics. It collects anonymous information such as:

• App installs, first opens and how often the app is used
• Screens visited and features used (for example the type of viewer or tool opened, backup actions such as connect, back up and restore)
• App language and theme (light or dark), app version, device model and Android version
• A random app instance identifier generated by Firebase

We do not send file names, document contents, your email address, or file paths to analytics. Analytics data is processed by Google as our service provider under Google's Privacy Policy and Firebase's privacy information. We do not use this data to identify you personally.

Cloud Processing & Online Viewer (PPTX Files)

To provide online viewing and processing features for presentation formats (such as PPTX files), files chosen by the user for online viewing may be transmitted to secure cloud storage infrastructure (Cloudinary). This data transmission is strictly used to render and provide the viewing feature and is encrypted in transit. If you prefer, presentations can also be viewed on your device without this step.

App Updates and Ratings (Google Play)

Dokvio uses Google Play's in-app update and in-app review features. Update checks and the rating sheet are provided and handled by Google Play. We do not receive the content of your review or any information about your Google account from these features.

Advertisements

Dokvio does not currently display advertisements. If this ever changes, we will update this policy and the app's Google Play disclosures before any advertising is introduced.

Data Retention and Deletion

Your documents and settings are stored on your device and are removed when you delete them in the app or uninstall the app. Backup copies live in your own Google Drive and are controlled by you, as described above. To ask about, or request deletion of, any data associated with your use of the app (for example analytics data), contact us at the email address below.

Security

Data sent over the internet by the app (Google sign-in, Google Drive backup, Firebase Analytics, and the PPTX online viewer) is encrypted in transit.

Children's Privacy

Dokvio is a general-purpose document tool and is not directed at children under 13. We do not knowingly collect personal information from children.

Changes to This Privacy Policy

We may update our Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date.
