Privacy Policy

Overview

DiveCast is committed to protecting your privacy. This Privacy Policy explains how we handle information when you use our dynamic dive planning application.

The short version: DiveCast does not collect any personal information unless you choose to sign in with Google or Apple. Even then, we only store the minimum information necessary to enable cloud synchronization of your dive plans.

Information We Collect

Local Usage (No Sign-In)

When you use DiveCast without signing in:

• We collect no personal information
• All dive plans and data remain stored locally on your device
• No information is transmitted to our servers
• No analytics or tracking data is collected

Cloud Sync (With Sign-In)

When you choose to sign in using Google or Apple authentication (SSO):

• Email address - Used as your unique identifier
• Name - Used for display purposes in the app
• Authentication tokens - Securely stored to maintain your session
• Usage logs - Automatically collected for debugging and stability improvements (see Usage Logging section below)

How We Use Your Information

If you choose to sign in, we use your information to:

• Authenticate your identity
• Enable cloud synchronization of your dive plans across devices
• Display your name in the application interface
• Associate your dive plans with your account for retrieval
• Collect usage logs for debugging and improving application stability (SSO users only)

We do not:

• Share your information with third parties

Usage Logging for SSO Users

When you sign in with Google or Apple authentication, we automatically collect usage logs to help us improve DiveCast's stability and performance:

• What we collect: Application logs, error reports, feature usage patterns, and debugging information

• How it's used: Solely for technical improvements and debugging purposes

Important: This usage logging only applies to users who sign in with SSO. Users who use DiveCast without signing in have no usage data collected.

Data Storage and Security

Local data: All dive plans created without signing in are stored locally on your device. We have no access to this data.

Cloud data: If you use cloud sync, your dive plans are stored securely in Firebase (Google Cloud Platform) with industry-standard encryption. Only you can access your dive plans through your authenticated account.

Usage logs: For SSO users, usage logs are securely stored in our cloud infrastructure and are retained for debugging and stability improvement purposes.

Authentication: We use OAuth 2.0 for secure authentication through Google and Apple. We never see or store your passwords.

• Data deletion: You can delete your account and all associated data at any time through the app settings
• Data export: You can export all your dive plans in standard formats
• Sign out: You can sign out at any time, which removes all authentication data from your device
