Privacy Policy

Controller and contact

Data Map Studio is provided by Xianchang Meng.

For privacy questions or support, contact [email protected].

Information the app may access

Data Map Studio may access information needed to operate the application, including:

• database connection settings that you enter;
• database schema metadata, such as table names, column names, keys, and relationships;
• query results that you choose to view, save, or export;
• saved Data Maps, working tables, import/export files, and local workspace settings;
• diagnostic information you choose to provide when asking for support.

Depending on the databases and files you use with the app, this information may include personal information.

Local-first processing

By default, Data Map Studio processes your workspace data locally on your device.

Data Map Studio does not send your database contents, table data, queries, saved maps, exported files, connection passwords, private signing keys, or user-created workspace data to Divohne servers or any cloud server.

Database credentials are stored locally on your device and are used only to connect to the data sources that you configure.

Data Map exports and imports

If you choose to export a Data Map, the exported file contains Data Map structure and metadata. Data Map exports are designed not to include database passwords or private signing keys.

If you import a Data Map, the app lets you review the imported structure locally. Imported maps do not automatically connect to your databases. You decide whether to bind imported map items to local data sources.

Store licensing and purchases

Data Map Studio is distributed through platform app stores, and each store manages installation, purchase, and licensing for its own platform:

• On Windows, the app is installed from Microsoft Store, which manages installation, purchase, licensing, and Free/Full feature availability.
• On Mac, the app is distributed through the Apple App Store, and Apple will manage installation, purchase, licensing, and Free/Full feature availability.

Microsoft Store processing. Microsoft may process purchase, licensing, installation, crash reporting, account, and device information according to Microsoft's own privacy policies and Microsoft Store terms. Data Map Studio uses Microsoft Store license information only to determine whether Free or Full features are available in the Windows app.

Apple processing. On Mac, Apple may process purchase, licensing, installation, crash and diagnostics reporting, Apple Account, and device information according to Apple's own privacy policies and the Apple Media Services / App Store terms. Apple processes the payment itself; Divohne does not receive your payment card details. Data Map Studio uses Apple App Store transaction and entitlement information only to determine whether Free or Full features are available in the Mac app.

StoreKit entitlements. The Mac app reads its purchase and entitlement state through Apple's StoreKit framework, using the app's StoreKit entitlement. The app uses this only to check which features are unlocked and to refresh or restore a purchase that you already made. Data Map Studio does not receive your Apple Account password or payment credentials, and it does not send your workspace data to Apple through StoreKit.

Purchases are separate between stores. A purchase made through Microsoft Store applies to the Windows app, and a purchase made through the Apple App Store applies to the Mac app. See Free vs Full.

Support requests

If you contact support, you may choose to send logs, screenshots, exported files, error messages, or other details needed to diagnose an issue.

Please do not send database passwords, secrets, private keys, or confidential production data in support requests unless specifically requested through a secure process.
