Selected files
Images, PDFs, videos, audio files, and GIFs, used only for the analysis, technical preview, and conversion you request.
Private by nature
Privacy Policy
Packetless converts images, PDFs, videos, audio files, and GIFs directly on your device. Files are never uploaded to a server, and the developer does not receive the content you process.
No uploads
Conversions are performed locally.
No trackers
No analytics, profiling, or advertising identifiers.
No advertising
No advertising SDKs and no sale of data.
No account
No registration, sign-in, or personal details required.
The short answer
Packetless does not collect or transmit personal data or usage data off your device. The app does not request Internet permission, create accounts, display ads, or include analytics, telemetry, remote crash reporting, or tracking systems.
1. Scope and developer
This Privacy Policy describes the privacy practices of the Android app
Packetless (application ID
com.dottorquantum.packetless), published by
DottorQuantum.
Packetless is an offline conversion tool. There are no Packetless user accounts, and DottorQuantum does not maintain a remote user database. Therefore, no account-deletion procedure is necessary.
2. Data and content processed locally
To perform the requested functions, the app accesses only the files you select through the Android system picker or voluntarily share with Packetless. Depending on the contents of the selected files, they may include personal data.
Technical metadata
Name, format, size, resolution, duration, page count, codec, and other information needed to offer compatible conversions.
Preferences
Language, theme, output folder, conversion options, notifications, and conversion-history preference.
Local history
When enabled, it stores file names and references, formats, status, sizes, duration, and any technical errors on the device.
This data is used on your device to provide the feature you selected. It is not sent to DottorQuantum or to third-party servers.
3. Network, trackers, analytics, and advertising
Packetless does not request android.permission.INTERNET.
The release configuration also excludes
android.permission.ACCESS_NETWORK_STATE. The app therefore
cannot independently upload files to the Internet or communicate with
a remote service.
Packetless does not include:
- advertising or advertising SDKs;
- analytics, telemetry, or usage measurement;
- remote crash reporting;
- cookies, fingerprinting, or profiling;
- collection of IP addresses, advertising IDs, or other device identifiers;
- sale, rental, or monetization of user data.
4. Android permissions and access
| Access | Purpose | Privacy behavior |
|---|---|---|
| Files and folders selected by the user | Read original files and save results. | Access is limited to items selected through system controls; the app does not request broad storage access. |
| Notifications | Display the progress and outcome of local conversions. | Android requests this permission when necessary. These are not push notifications, and no token is sent to a server. |
| Foreground service | Complete lengthy processing while the app is in the background. | The Android categories “media processing” and “data sync” describe the service’s local work; they do not indicate online synchronization. |
| Wake lock | Prevent an active conversion from being interrupted by device sleep. | It does not permit access to personal data or enable network communication. |
For some operations, Android may retain permission to access the selected file or folder while the app remains installed. This allows a local conversion to be completed, retried, or reopened. You can revoke this access by clearing the app’s data or uninstalling it.
5. Voluntary sharing, providers, and third-party components
User-initiated actions
Packetless does not automatically share files or data. If you select “Share,” “Open,” or a similar action, Android passes the result only to the app you choose. From that point onward, processing is governed by the recipient app and its privacy policy.
Folders and services shown by the Android picker
The system picker may display providers installed on the device, including cloud services. If you intentionally select a file or folder managed by one of these providers, that provider may download or sync the content under its own terms. Packetless neither performs nor controls that transfer and still has no Internet permission.
Included libraries
The app uses bundled software components, including AndroidX/Jetpack, Media3, PDFBox-Android, FFmpeg, and LAME. They are used for the user interface, storage, and on-device conversions. In the Packetless configuration, they do not send files, analytics, or telemetry to third parties.
6. Retention and deletion
| Item | Retention period | User control |
|---|---|---|
| Temporary files | Only for the time needed to perform the conversion; they are deleted when possible and cleaned up at the next launch. | They can be removed from “Temporary files” in Settings. |
| Conversion history | It remains in the local database while the feature is enabled. | It can be cleared or disabled in Settings. |
| Results in the app’s private folder | They remain available until deleted or the app is uninstalled. | They can be deleted from the app. |
| Results in a selected folder | They remain in the selected location even after uninstallation. | You must delete them using the app or the relevant file manager/provider. |
| Local preferences | They remain until the app’s data is cleared. | Clear Packetless data in Android Settings or uninstall the app. |
Packetless has no remote copies to delete. Uninstalling the app deletes data and output files in the app’s private folder, but it does not delete files you chose to save in external folders.
7. Security, backups, children, and purchases
Security measures
Data minimization is part of the architecture: local processing, no Internet permission, selective document access, non-exported internal components, and sharing only when initiated by the user. Cloud backup and automatic transfer of the app’s private data to a new device are disabled.
The physical and logical protection of your files also depends on the security of your device, the Android operating system, your screen lock, and the apps or providers you choose to use.
Children
Packetless is not designed to collect information about children and does not knowingly collect children’s personal data. It does not include advertising, profiling, social features, or account creation.
Purchases through Google Play
Any purchase and related payment data are handled by Google Play under Google’s policies. Packetless does not receive or store card numbers, payment credentials, or banking information.
8. Changes and contact
This Privacy Policy may be updated if the app’s features, processing practices, or applicable obligations change. The effective date shown at the top identifies the current version. Material updates will be made available on this page and, where appropriate, in the app or on its Google Play listing.
Privacy contact
For questions or requests, use the email address published in the
“Developer contact” section of the Packetless Google Play listing. If
you voluntarily contact DottorQuantum, the data included in your
message will be used only to handle and respond to your request.
