Privacy Policy

Effective date: March 6, 2026

This Privacy Policy applies to the Weather Fusion app for iPhone, iPad, and Mac.

During pre-release testing, Weather Fusion may process limited usage and error telemetry during app use, and optional support data when you choose to send a bug report.

1. Scope

This policy covers local app data, telemetry used for product reliability, and optional support bug reports.

2. Data in the App and Data Sent to Us

Depending on how you use the app, data categories are:

• Data stored by the app on your device: app preferences and downloaded weather observations;
• App data synchronized in iCloud when iCloud is enabled;
• Usage and error telemetry that may be sent automatically during pre-release testing: app and platform metadata (including locale, language, region, and app timezone offset), sanitized provider and settings state (including selected station country when available), database diagnostics metadata (for example observation counts, metric name lists, summary counts, data time ranges, and database file size/name metadata), app mode/navigation/dashboard layout and inspector interaction metadata, and canonical error and outcome classifications;
• Optional bug report data sent only when you choose to send a bug report email: app/device configuration and recent observations, with credentials and network identifiers removed.

3. How Data Is Collected

When pre-release telemetry is enabled, usage and error telemetry is generated automatically while you use the app, including app lifecycle, refresh and sync outcomes, import and export outcomes, content mode changes, inspector open/close and tab selections on macOS, historical period picker selections, observations view mode switches, settings and activity panel navigation events, summary recalculation requests, provider connection and station refresh outcomes, and settings changes.

At app startup, telemetry also includes a database snapshot with aggregate counts and timing ranges used to diagnose data freshness, migration quality, and reliability issues.

Support data is sent only if you choose to send a bug report email.

Telemetry uses a runtime session ID that resets on every app launch and is never persisted across launches.

4. Data Minimization and Exclusions

Telemetry payloads are designed to include only sanitized operational context. In telemetry payloads, we do not collect:

• API keys, secrets, passwords, tokens, or raw credentials;
• Provider endpoint URLs, hosts, IP addresses, station IDs, or provider-side unique station identifiers;
• Precise coordinates or raw weather payloads;
• User identity, account identifiers, contact details, or stable install-level identifiers.

5. Why We Process Data

We process data to:

• Provide app features, including local storage of weather history and settings;
• Understand feature usage and improve reliability;
• Diagnose and resolve technical issues, including support requests you initiate.

6. Storage and Retention

App data remains on your device and can be synchronized in iCloud.

Bug reports remain on your device until you send them.

If you send a bug report, we keep support data only as long as needed to resolve your request.

When pre-release telemetry is enabled, telemetry records are retained only as long as needed to evaluate reliability, diagnose failures, and improve the app.

Telemetry is processed with session-only context and without stable cross-session identifiers.

7. Sharing

We do not sell your data.

Telemetry and support reports are not shared with third parties for marketing or profiling.

8. Your Rights and Contact

If you want to request deletion of support communications you sent us, contact: [email protected]

You can also contact us with privacy questions at the same address.

9. Updates

We may update this Privacy Policy from time to time. Updated versions will include a revised effective date.
