This Privacy Policy describes how WinLune ("we," "us," or "our") handles information when you use the WinLune FX application (the "App"). We are committed to protecting your privacy and being transparent about the limited data the App uses.
WinLune FX does not require you to create an account, provide an email address, or submit any personal information to use the App. The App is fully functional without registration of any kind.
We do not collect, store, or transmit:
The App stores the following data locally on your device only, using standard device storage mechanisms (UserDefaults on iOS, localStorage on web). This data never leaves your device and is not accessible to us:
This locally stored data can be cleared at any time by uninstalling the App or clearing your browser site data.
To display current exchange rates, the App makes network requests to the following third-party services:
open.er-api.com — Fiat currency exchange rates. Free public API.api.gold-api.com — Precious metals spot prices (Gold, Silver, Platinum, Palladium). Free public API.api.coingecko.com — Cryptocurrency market prices. Free public API.djgtzbuyipyhqwtlwmee.supabase.co — Anonymous usage events (see Section 6 below).These requests are made directly from your device. The third-party providers may collect standard server log data such as your IP address and request timestamp in accordance with their own privacy policies. We do not control and are not responsible for the data practices of these providers.
WinLune stores only anonymous usage events (see Section 6 below) in a hosted database (Supabase). No personal information is transmitted to servers controlled by WinLune.
The App does not use cookies, advertising identifiers, tracking pixels, or any cross-site tracking technology. The App does not display advertisements and does not share data with advertising networks.
We collect anonymous usage data to help us understand how the App and website are used and improve our features. Specifically, we record the following events:
Each event is associated with a randomly generated session identifier (UUID) created on your device at first launch (or first website visit) and stored in local device storage. For website page views, a coarse country may be derived from your IP address or browser language; for the mobile app, your device region setting may be recorded. This data is not linked to your name, Apple ID, email address, or any other personally identifiable information. We do not use this data for advertising and do not sell it to third parties.
You may reset the session identifier by uninstalling and reinstalling the App, or by clearing your browser site data.
The App is not directed at children under 13 years of age, and we do not knowingly collect personal information from children. Since the App collects no personal information from any user, this policy applies equally regardless of age.
Because the App stores data only locally on your device and transmits no personal information to our servers, the primary responsibility for data security rests with your device's security settings (device lock, encryption). We encourage you to keep your device's operating system and security features up to date.
Because we do not collect or store personal data on our servers, there is no personal data held by WinLune for us to provide, delete, or correct. To remove locally stored preferences and cached rate data, simply uninstall the App or clear site data in your browser.
The App may contain links to third-party websites for informational purposes. We are not responsible for the privacy practices of those websites and encourage you to review their privacy policies independently.
We may update this Privacy Policy from time to time. We will notify you of significant changes by updating the effective date at the top of this page. Your continued use of the App after changes are posted constitutes acceptance of the updated policy.
