Device Hub: ADB & File Manager
Device Hub: ADB & File Manager
Last updated: September 27, 2026
This Privacy Policy explains how Krepel Studio (“we,” “us,” or “our”) handles information when you use Device Hub — ADB & File Manager (“Device Hub” or the “App”).
Android package name: com.krepelstudio.devicehub
Developer website: https://krepelstudio.com/
Privacy contact: Krepelstudio@gmail.com
Device Hub lets you connect Android devices over a local network or USB, manage and transfer files, preview supported files, manage applications and APK installations, view device information, capture screenshots, and retrieve diagnostic logs.
You do not need to create a Krepel Studio account to use the App.
Most processing of your files and connected-device information takes place on your devices. Device Hub does not automatically upload this content to a Krepel Studio server. Google Play, Android backup services, document providers you select, and support communications may involve separate processing, as described below.
To discover, identify, connect to, and display your devices, Device Hub may process:
Device names, models, and manufacturers.
Android versions, API levels, firmware information, build numbers, and security patch levels.
Processor, architecture, memory, and storage information.
Battery levels and charging status.
Local network addresses, connection ports, connection types, connection status, and available network characteristics.
ADB identifiers, key fingerprints, and connection timestamps.
USB vendor and product identifiers and, where available after permission is granted, USB device serial numbers.
Some of this information is stored locally so the App can display saved devices and reconnect to them.
Depending on the features you use, the App processes file names, paths, types, sizes, modification times, and file contents. These may include documents, photographs, videos, audio files, APK packages, and other accessible files.
The App may store file metadata, operation history, checksums, error information, and progress records locally to support browsing, transfers, and the handling of incomplete operations.
Temporary local copies may be created when previewing or transferring files or preparing APK installations.
When you request the corresponding action, Device Hub may retrieve a connected device’s application list, capture its screen, or read system and diagnostic logs available through ADB.
Screenshots and logs may contain personal or confidential information, including information from other applications. Device Hub does not automatically redact all such information. Review these files before exporting them or sharing them with anyone.
The App stores preferences such as your selected language, theme, onboarding status, battery alert settings, and other operational settings.
It also stores your Pro access status and information needed to determine whether previously verified access remains valid.
Device Hub uses the permissions and access mechanisms described below. A permission does not, by itself, mean that information is transmitted to the developer.
Permission or access
Purpose
MANAGE_EXTERNAL_STORAGE — All files access
Enables the App’s file-management functionality, including finding, browsing, copying, moving, renaming, and deleting accessible files and folders in the main device’s shared storage.
INTERNET
Enables network communication, including local ADB connections and communication with Google Play.
ACCESS_NETWORK_STATE and CHANGE_NETWORK_STATE
Support network-state handling and network connections to devices.
ACCESS_LOCAL_NETWORK
Enables discovery of and connections to devices on your local network on Android versions where this permission applies.
CHANGE_WIFI_MULTICAST_STATE
Supports local ADB device discovery on applicable older Android versions.
FOREGROUND_SERVICE and FOREGROUND_SERVICE_CONNECTED_DEVICE
Support device connections and long-running operations you initiate, including while the App is in the background.
POST_NOTIFICATIONS
Enables notifications about connections, operations, and low battery levels on connected devices.
WAKE_LOCK
Helps prevent the processor from sleeping during active long-running operations.
com.android.vending.BILLING
Enables purchases, purchase verification, and restoration of Pro access through Google Play.
Android’s per-device USB permission
Enables communication with a specific USB device after you approve access.
The App also includes the internal permission com.krepelstudio.devicehub.DYNAMIC_RECEIVER_NOT_EXPORTED_PERMISSION. This protects internal message handling and does not provide additional access to your personal information.
All files access does not bypass Android’s security protections or automatically grant access to other applications’ private data.
Device Hub does not request separate permissions to access your camera, microphone, contacts, SMS messages, call history, or location. However, information of these types may be present in files, screenshots, or logs that you choose to process.
You can decline or revoke permissions through Android settings. Features that require the relevant permission may then become unavailable.
ADB provides extensive capabilities for managing a connected device. Only connect devices you own or are authorized to manage.
Wireless debugging pairing or USB debugging authorization establishes a trusted connection. Device Hub uses that connection to perform actions you request and obtain information necessary for those actions.
For certain file operations, the App may transfer a temporary helper file to the connected device. This does not install a separate Android application. The App attempts to remove the helper after use, but a connection interruption or unexpected shutdown may leave temporary files behind.
After you initiate a connection, Device Hub may maintain or restore that connection in the background, continue active operations, and check connected-device battery levels when battery alerts are enabled.
Notifications may display device names, battery levels, and operation information. Whether this information appears on your lock screen depends on your Android notification settings.
You can disconnect devices, stop an operation, or disable battery alerts. Merely leaving the App’s screen does not necessarily stop background work that you have already started.
Device Hub uses Google Play Billing for monthly and yearly subscriptions, eligible trial offers, and a one-time Lifetime Pro purchase.
Google processes payments and the associated payment information. Device Hub does not receive your full payment card number, card security code, or Google Account password.
The App receives product information, available offers, prices, purchase status, and purchase identifiers needed to verify and restore access. Purchase checks may occur when the App starts, not only after you select a purchase option.
Purchase tokens are used to process purchases through Google Play. The App does not write these tokens to its own persistent local storage. It stores access status and related verification information locally.
Google Play and its components may process technical and diagnostic information under the Google Privacy Policy.
Reviewer Access is verified locally and does not create a payment or subscription.
Device Hub transfers files and commands between devices that you connect and select for an operation. Bulk copying or APK installation sends the relevant data to each selected destination device.
When you export a result using Android’s document picker, the data is written to the location you select. If you choose a cloud document provider, that provider’s privacy policy also governs its subsequent handling of the data.
The current version of Device Hub does not display advertisements or include a separately integrated advertising analytics system. Krepel Studio does not sell information processed by Device Hub or use your file contents for advertising profiling.
When you open an external website or use an email service, the relevant browser, website, or email provider applies its own terms and privacy practices.
If you contact support, we receive your email address, your message, and any attachments you voluntarily provide. We use this information to address your request. Do not send passwords, ADB private keys, payment credentials, or unnecessary personal information.
Third-party providers, including Google and email providers, may process information outside your country under their applicable privacy policies.
Saved devices, preferences, operation history, and results may remain on your main device between App sessions.
Saved screenshots and diagnostic logs do not have an automatic expiration period. Closing a viewer, disconnecting a device, or forgetting a device does not delete all previously created results or operation history.
Temporary files are removed by the relevant cleanup mechanisms. Following an unexpected interruption, cleanup may occur the next time you use the relevant feature rather than immediately.
Depending on your system settings, Android may back up some App preferences, including notification settings and identifiers used to remember which battery alerts have already been shown. The App’s backup rules exclude the device and operation database, saved screenshots and logs, ADB credentials, and locally stored Pro entitlement information.
You can manage your data by:
Using Forget device to remove a saved device entry and its local trust credentials.
Separately revoking ADB authorization in the debugging settings of the connected device.
Clearing Device Hub’s App data or uninstalling the App to remove its private local storage.
Separately deleting exported files, transferred copies, and backups from their respective storage locations.
Uninstalling Device Hub does not automatically delete files on other devices, applications installed through Device Hub, or exported results. It also does not cancel a Google Play subscription. Subscriptions must be managed through Google Play.
Support correspondence is retained for as long as necessary to address the request and, where justified, to meet legal obligations or resolve disputes. You may contact us to request deletion of support correspondence.
ADB private credentials are encrypted locally using a key protected by Android Keystore. Wireless Debugging connections use the protected ADB protocol. USB connections use a physical connection following the required authorization.
This does not mean that every file or database record is separately encrypted by Device Hub. Your device’s security settings, screen lock, Android updates, and the security of connected devices also affect the protection of your information.
No method of storage or transmission can guarantee absolute security. Do not grant ADB access to unknown or untrusted devices or people.
Depending on applicable law, you may have rights to access, correct, delete, restrict, or obtain a copy of your personal information, object to certain processing, or withdraw consent where processing relies on consent.
To submit a privacy request, contact Krepelstudio@gmail.com. We may request the minimum information necessary to verify that you are entitled to make the request.
Krepel Studio does not have remote access to Device Hub’s local files on your device. You must manage or delete those files on the device itself. Information independently processed by Google or another provider must also be managed through that provider’s available controls.
Where applicable, you may lodge a complaint with the relevant data protection authority.
Device Hub does not request dates of birth or create child profiles. If a minor uses the App, the necessary permissions and actions must comply with applicable law and the requirements of a parent or legal guardian.
If you believe that a minor has provided personal information to us through support without the necessary authorization, contact us so that we can investigate and remove the relevant information where appropriate.
We may update this Privacy Policy when the App’s functionality, data-handling practices, or applicable requirements change. The current version will display its revision date.
Where a change requires additional notice or consent, we will provide the required notice or obtain consent before beginning the relevant processing.
