What Data We Process

Account Data

SiteWinds does not require account creation. We do not collect usernames, passwords, or account profiles.

App Preferences Stored Locally

SiteWinds stores settings such as your selected home launch, favorites, and visualization preferences locally on your device to make the app work as expected. This data never leaves your device.

Weather Snapshot Requests

When you use SiteWinds, the app requests real-time or near real-time wind readings (and recent reading history) from the SiteWinds API for map regions around selected coastal and inland sites. These requests are made by map region, not by your personal GPS coordinates.

Subscriptions and Entitlements (RevenueCat)

SiteWinds requires an active subscription ("SiteWinds Pro") to access the full app experience after the initial free preview period. When you subscribe, restore purchases, or when the app checks your subscription status, RevenueCat processes subscription and entitlement information so the app can verify access, restore purchases across devices, and keep your subscription status in sync.

We do not require an account for Pro access. If you contact support, we may use the anonymous RevenueCat app user ID to help look up your subscription state.

Optional Device Location

SiteWinds includes an optional My Location feature. If you turn it on in Settings and grant location permission, the app reads your device's precise GPS coordinates to show your current position on the map.

Anonymous Usage Analytics (PostHog)

We use PostHog (hosted in the EU) to understand product usage and improve the app. Analytics are sent over HTTPS using a custom integration. We do not use PostHog autocapture, session replay, or screen recording.

SiteWinds sends only these explicit events:

Each event also includes:

We use this data to understand which regions and stations users engage with so we can prioritize coverage and product improvements. PostHog may also receive standard request metadata (such as IP address) as part of normal web traffic; see PostHog's privacy policy for how they handle that data. Analytics data is retained for up to 12 months.

Crash and Performance Diagnostics (Sentry)

We use Sentry to diagnose crashes, app hangs, and performance issues. Sentry may receive:

This data helps us fix bugs and improve reliability. It is separate from PostHog usage analytics. Sentry is operated by Functional Software Inc. (USA); data may be stored and processed in the United States.

What We Do Not Collect

How We Use Data

No Advertising and No Ad Tracking

SiteWinds does not display advertisements. We do not use advertising SDKs, and the app does not collect or share any data for advertising purposes. We do not request access to the iOS Identifier for Advertisers (IDFA) or use any fingerprinting techniques for ad targeting. The app's iOS privacy manifest declares NSPrivacyTracking = false and an empty collected data types array.

International Data Transfers

SiteWinds is operated from New South Wales, Australia. Some of our third-party service providers are located outside Australia and may store or process your data overseas:

Where data is transferred outside Australia, we take reasonable steps to ensure overseas recipients handle it in a manner consistent with the Australian Privacy Act 1988, including by relying on the contractual protections and privacy commitments of each provider.

Data Security and Retention

Your Privacy Rights and Data Deletion

Depending on where you live (including under the Australian Privacy Act 1988, GDPR, and CCPA/CPRA), you may have rights to access, correct, or delete personal information we hold about you, or to object to certain processing. Because SiteWinds does not require an account, much of your data stays on your device or is stored under anonymous identifiers.

Children's Privacy

SiteWinds is not directed to children under 16. We do not knowingly collect personal information from children under 16. If you are under 16, you must have obtained verifiable consent from a parent or legal guardian before using the app, in accordance with the Australian Privacy Act 1988. If we become aware that we have inadvertently collected personal information from a child under 16 without appropriate consent, we will take steps to delete that information promptly.

Changes to This Policy

We may update this policy from time to time. The date at the top of this page reflects the latest version. Continued use of the app after changes are posted constitutes acceptance of the updated policy.
