Krepel Studio (“we,” “us,” or “our”) develops DJ Scratch: Vinyl Mixer (“DJ Scratch” or the “App”), an Android application for playing and scratching selected audio tracks, mixing two decks, applying DJ effects, recording mixes, and exporting audio.
This Privacy Policy explains what information the App accesses, how it is used and stored, when information may be handled by other services, and the choices available to you.
The App allows you to select audio files using Android's system file picker. When you choose a file, the App may access its contents and technical metadata, such as its name, format, duration, and audio characteristics, to load and play the track, display a waveform, estimate BPM, and perform scratching and mixing.
Audio decoding, effects, the built-in sample pads, BPM analysis, recording, and preparation of exported mixes are designed to run locally on your device. The App does not upload your selected tracks, waveform data, recordings, or exported mixes to Krepel Studio servers.
The App also stores information needed for its features, which may include:
The locations or document identifiers of audio files you selected, and the access permissions granted through Android.
The last DJ session, playback positions, cue points, loops, speed, key lock, effects, mixer levels, and BPM-related settings.
Your selected language, theme, haptic feedback preference, and other application settings.
Temporary audio caches, recording previews, unfinished recording drafts, and export files while they are being prepared.
This information is used to provide the features you request and restore your settings. It is not used to create an advertising profile.
User-selected audio files remain in their original locations. The App uses access granted by Android's file picker rather than requesting unrestricted access to your device's storage.
The App may create temporary decoded audio data and recording files in its private application storage. These files are used for playback, scratching, previewing, recording, recovering interrupted work, and exporting mixes.
In the Free version, a recording preview is limited to 30 seconds and is available only within the App; exporting or sharing the audio is not available without Pro. In Lifetime Pro, you can choose to export a mix as MP3, WAV, or M4A to a location you select.
When you choose an export destination or use Android's Share feature, your file is transferred only as you direct. A destination or sharing app may be operated by another provider, including a cloud storage provider. Its handling of the file is governed by that provider's privacy practices.
DJ Scratch's audio editing and mixing functions are designed for on-device use and do not require you to create a Krepel Studio account.
The App does not include advertising or AdMob, and we do not use its audio content for advertising or behavioral profiling. There is no advertising SDK or advertising identifier required for the planned functionality.
An internet connection may be needed to purchase or restore Lifetime Pro through Google Play, open this Privacy Policy, or access services you voluntarily choose outside the App. The App does not offer an audio-upload or cloud-mixing service operated by Krepel Studio.
DJ Scratch offers an optional, one-time Lifetime Pro purchase through Google Play Billing. Google Play handles the payment transaction under Google's own terms and privacy practices.
To provide and restore your purchase, the App may receive and process purchase-related information supplied by Google Play, such as the product identifier, purchase status, and purchase token. Such information is used to verify and maintain access to Pro features.
Krepel Studio does not ask you to enter payment card details into the App and does not receive your complete card number through Google Play Billing. Your Google Play account and payment information are handled by Google.
For more information, see Google's Privacy Policy.
Depending on your Android version and the features you use, the App may rely on the following Android permissions and system capabilities:
Selected-file access (Storage Access Framework): To open only the audio files you choose and create exported files in a destination you select. This does not require unrestricted storage access.
Foreground service and media playback: To support user-initiated playback and mixing while the App is in the background, with appropriate system-visible playback controls.
Media processing foreground service: To complete longer audio export or conversion tasks, when required by your Android version.
Notifications (POST_NOTIFICATIONS on supported Android versions): To show permitted playback, recording, or export status and controls. Android may ask for notification permission when applicable.
Audio settings (MODIFY_AUDIO_SETTINGS): To manage supported audio playback behavior and output settings.
Wake lock (WAKE_LOCK), when needed: To keep necessary processing active during user-requested playback or recording, and release the lock when the work ends.
Vibration (VIBRATE): To provide optional tactile feedback when you touch or move a vinyl record or use supported controls. You can turn this feedback off in the App.
DJ Scratch does not require microphone recording permission to record mixes. It records audio generated inside its own mixing engine, not sound captured from your microphone or audio playing in other applications.
The App is not designed to require location, contacts, camera, accessibility, broad storage access, or screen-capture permissions for its approved DJ features.
The App is designed to use Android system media components and local audio-processing libraries to perform audio functions on your device. These software components do not, by themselves, mean that your music is uploaded to their developers.
Google Play services are used for in-app purchases and may process purchase-related or device information according to Google's policies. Android and Google Play may also provide platform-level crash, performance, or security diagnostics through their own services and settings.
If you contact us by email, we will receive the information you choose to include in that message and use it to respond to your inquiry. Your email service provider may process the communication under its own policy.
We do not sell your personal information. We do not intentionally send the audio files you select or the mixes you record to advertising networks, analytics providers, or our own servers.
App settings, remembered file references, and session information may remain in local application storage until you reset them, clear the App's data, or uninstall the App, subject to your device's backup settings.
Temporary audio caches and recording previews are intended for use within the App and may be cleared when no longer needed, when you discard them, or during application cache cleanup. Do not rely on temporary previews as permanent copies.
Exported mixes saved outside the App remain in the destination you selected until you delete them or the destination provider removes them. Uninstalling DJ Scratch may not remove exported files stored elsewhere.
The App does not require a Krepel Studio account, so there is no in-app Krepel Studio account to delete. To remove local application information, use the App's available deletion controls or Android's app storage settings. To request deletion of information that you voluntarily sent to us by email, contact Krepelstudio@gmail.com. We may retain limited correspondence when necessary to address a request or comply with legal obligations.
We aim to minimize access to user data. The App is designed to rely on Android's application sandbox, user-selected document access, limited file-sharing permissions, and local processing. Purchase handling uses Google Play's billing mechanisms.
No method of storage or transmission can be guaranteed completely secure. Your device's security settings, the storage provider you select, and the sharing services you use also affect the security of your information.
You can choose which audio files to open, whether to use optional haptic feedback, whether to allow applicable notifications, whether to purchase Lifetime Pro, and whether to export or share a mix.
You can revoke document access where supported, delete exported audio from its destination, clear local app data, or uninstall the App. Depending on applicable law, you may also contact us to inquire about, correct, or request deletion of personal information that we actually hold, such as support correspondence.
We cannot directly delete data managed solely by your device, Google Play, or another storage or sharing provider; please use that provider's available controls.
The App does not require users to submit personal information to Krepel Studio to use its audio-mixing functions. We do not knowingly seek personal information from children through these functions. If you believe a child has sent personal information to us through a support inquiry, contact us so we can review and appropriately handle the request.
We may update this Privacy Policy when the App's functionality, data practices, integrated services, or applicable requirements change. We will publish the updated text with a revised “Last updated” date. Please review the policy periodically.
