2. Overview

KeyVault Studio is designed with privacy in mind. We collect minimal data necessary to provide our service and never sell or share your personal information with third parties.

3. Data We Collect

3.1 Authentication Data

  • Microsoft Azure account credentials (stored securely in macOS Keychain)
  • Authentication tokens from Microsoft (encrypted and stored locally)
  • Azure subscription and tenant information

3.2 Application Data

  • User preferences and settings (stored locally on your device)
  • Key Vault access history (stored locally)
  • Error logs for debugging (stored locally, never transmitted)

3.3 Analytics Data

We do NOT collect:

  • Usage analytics
  • Performance metrics
  • Crash reports (unless explicitly shared via TestFlight)

4. How We Use Your Data

Important: KeyVault Studio acts as a client application that connects directly to Microsoft Azure. Your authentication credentials are sent directly to Microsoft's authentication servers, not to our servers.

  • To authenticate you directly with Microsoft Azure services (credentials go directly to Microsoft)
  • To manage your Azure Key Vault resources through Microsoft's APIs
  • To save your application preferences locally on your device
  • To provide customer support when you explicitly request it

We do NOT have access to your Azure credentials or the contents of your Key Vaults. All communication happens directly between your device and Microsoft Azure.

5. Data Storage and Security

  • All sensitive data is stored locally on your device
  • Authentication tokens are encrypted using macOS Keychain
  • We use industry-standard encryption (AES-256)
  • No data is transmitted to our servers
  • All Azure communication uses Microsoft's secure APIs

6. Third-Party Services

Microsoft Azure

KeyVault Studio connects to Microsoft Azure services. Your interactions with Azure are governed by Microsoft's Privacy Policy.

TestFlight (Beta only)

If you participate in our beta program, Apple TestFlight may collect crash logs and usage data according to Apple's Privacy Policy.

7. Your Rights (GDPR)

Under the General Data Protection Regulation (GDPR), you have the right to:

  • Access your personal data
  • Correct inaccurate data
  • Request deletion of your data
  • Object to data processing

All data is stored locally on your device and remains under your control. You can delete all app data at any time by:

  • Uninstalling the application
  • Using the "Clear All Data" option in settings
