Privacy Policy
DeckDiag does not collect your data. There is no account, no sign-in, no analytics, no advertising and no tracking. App data stays on your device unless you share it or enable a shared event folder. Your selected folder provider may sync that data to other devices or services.
What the app keeps on your device
To do its job, DeckDiag saves the following in its private storage on your device. DeckDiag does not upload this data to a developer-operated server. Optional sharing and shared folders are described below.
| Item | Why |
|---|---|
| Your name | Printed on reports as “Checked by” or “Technician”. Optional. |
| Business name and contact | Shown on service reports. Optional, Service mode only. |
| Check results | Test results, firmware versions, unit labels, customer names and notes you type. |
| Event and stage names | Used to group stage checks and their summaries. |
| Part numbers | Entries you make in Resources. |
| Photos you add | Copied into the app so they can appear on your service reports. |
| Settings | Your chosen mode, preferences, device identifier for team files, and access bookmarks for folders you choose. |
This data may be included in your device backups according to your own backup settings. Deleting the app removes its private app storage; exported files, shared-folder copies and backups may remain and must be managed separately.
Connecting to your equipment
- USB: when you connect a supported unit, DeckDiag reads the control messages it sends (button presses, fader and jog movement) and, on Mac, its USB model and firmware information. This stays on your device.
- Local network: DeckDiag can listen for DJ equipment announcing itself on your local network (PRO DJ LINK). Apple platforms may ask for Local Network permission. Network scanning on iPhone and iPad is awaiting Apple’s multicast entitlement and is not yet confirmed available. By default DeckDiag only listens. If you turn on the optional Full Link check in Settings, DeckDiag briefly announces itself on the DJ network as an extra player so the players report their status (firmware, play state, tempo, loaded media) and, if Read media summary is on, the name, track count and free space of the media in each player. The optional media summary sends a read-only request to the player. DeckDiag sends no playback, configuration or firmware commands and does not open audio files. This diagnostic traffic is local to the equipment network.
Camera and photo library
- DeckDiag asks for the camera or photo library only when you tap Add photo, to document a fault or the condition of a unit.
- Only the photos you pick are copied into the app. DeckDiag does not browse or upload your library.
- When you save a summary image to Photos, your device asks permission to add that image.
Location and iOS privacy declarations
DeckDiag does not request or use your location. Its iOS permission text includes a location explanation because a bundled component contains location APIs. The app’s privacy manifest declares no tracking and no collected data types, and declares file-timestamp access for app files and system boot time for elapsed-time measurements.
Shared event folders
When you link an event to a folder, DeckDiag retains a platform access bookmark, reads teammates’ event files, and writes this device’s event updates. Updates can sync after you save a linked event. These files contain event and stage information, unit check results and the checker’s name. The folder’s permissions determine who can access them.
If you choose iCloud Drive or another cloud or network folder, that provider may transfer and store the files under its own terms. Unlinking stops DeckDiag’s use of the folder; it does not delete copies already shared. Manage those copies and access rights in the folder provider.
Sharing
Reports, PDFs and summaries can leave the app through the share sheet, clipboard, export destinations, or optional linked event folders. You choose the recipient, and that app’s own privacy terms then apply.
Third parties
DeckDiag contains no analytics, advertising or tracking software. It uses standard open-source components to show the share sheet, pick photos, make PDFs and store files locally; sharing and folder access operate through your selected system services and providers.
- App Store: if subscriptions launch, payment processing will be handled by Apple; DeckDiag will not receive your full card details. Paid purchase handling is not implemented in the current beta.
- TestFlight beta testers: Apple’s TestFlight service shares some information with the developer: your name and email address as a tester, crash reports, device model and OS version, and any feedback or screenshots you send. See Apple’s TestFlight terms for details.
This website and support messages
This website loads fonts from Google Fonts, which causes your browser to contact Google and expose connection details such as your IP address. The local-network PC package uses system fonts and makes no font requests. The website contains no analytics or advertising scripts. If hosted publicly, its hosting provider may process request logs under its own policy.
If you email support, we receive your email address and whatever information or attachments you send. Send only the information needed for your request. You may contact us to ask about deletion of support correspondence.
Children
DeckDiag is a tool for DJs and equipment technicians and is not directed at children under 13.
Changes to this policy
If this policy changes, the new version will be posted on this page with a new effective date. A change that affects your data would never apply to data you created before it without your consent.
