Privacy Policy

Effective date: March 11, 2026

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

Weather Fusion stores app data on your device, can synchronize it through iCloud when enabled, processes app telemetry unless you disable it in Settings, and may process optional support data when you choose to send a bug report.

1. Scope

This policy covers local app data, app telemetry used for analytics and 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;
• Automatic app telemetry sent while telemetry is enabled: runtime and device metadata added by TelemetryDeck, plus app-defined usage and diagnostics data such as active app surface, selected mode, provider and station-refresh outcomes, refresh and sync outcomes, import and export outcomes, storage diagnostics, selected station metadata profile fields when available, including station country code and station time zone identifier, and sanitized MetricKit diagnostic summaries for crash, hang, CPU exception, disk-write exception, and on iOS app-launch diagnostics;
• 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

App data is stored locally while you use Weather Fusion and may be synchronized through iCloud when enabled.

Telemetry is enabled by default unless you disable it in Settings. When enabled, telemetry is sent automatically through TelemetryDeck while you use the app.

Telemetry includes SDK-managed runtime and device metadata such as app version and build, platform and OS version, device model and screen characteristics, locale, language, region, time zone, and run-context flags. The app does not set a custom telemetry user ID.

App-defined telemetry also includes feature usage and operational outcomes, including onboarding, provider setup, station selection, connection tests, realtime refreshes, historical syncs, import and export outcomes, Data Details storage telemetry, navigation destinations, and selected station metadata profile fields after successful station refreshes when available.

TelemetryDeck also sends an SDK-managed hashed device-scoped identifier and session ID.

According to TelemetryDeck's published documentation, TelemetryDeck does not store IP addresses for this telemetry processing and does not use cookies or comparable tracking technologies for it.

MetricKit diagnostics may also be delivered by the OS on a later launch and, when received while the app is running, are forwarded to TelemetryDeck as sanitized diagnostic summaries.

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

4. Data Minimization and Exclusions

Telemetry payloads and bug reports are designed to include only the data needed to operate, analyze, and support the app. We do not collect:

• API keys, secrets, passwords, tokens, or raw credentials;
• Provider endpoint URLs, hosts, or IP addresses;
• Raw station IDs, station names, raw locality strings, or raw provider details JSON;
• Precise coordinates or raw weather payloads;
• Raw MetricKit diagnostic payload JSON, raw MetricKit call stack trees, or Objective-C exception reason text;
• Custom install IDs, custom user IDs, or app-managed session IDs;
• User identity, account identifiers, or contact details unless you choose to send them in a support email.

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 app 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.

Telemetry records are kept only as long as needed for analytics, reliability investigation, and product improvement.

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.

7. Sharing

We do not sell your data.

Telemetry is processed through TelemetryDeck for analytics and diagnostics.

TelemetryDeck GmbH, Von-der-Tann-Str. 54, 86159 Augsburg, Germany, is our telemetry service provider for this processing. More information about TelemetryDeck's privacy practices is available at https://telemetrydeck.com/privacy and https://telemetrydeck.com/docs/guides/privacy-faq/.

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

8. Your Rights and Contact

You can disable app telemetry in Settings at any time.

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