FX Strength — Currency Meter ("FX Strength", "the App", "we", "us", or "our") is an iOS app developed by SignalDeck. This Privacy Policy explains what information the App does and does not collect.
The short version: FX Strength does not collect any personal data. There is no account, no sign-in, and nothing you enter or view in the App is sent to us or stored on any server we control.
1. Information We Collect
None. FX Strength has no account system, no user-generated content, and no analytics or tracking SDKs embedded in the App. We do not know who you are, and we have no way to identify individual users.
2. Network Access
The App makes network requests to the following, and only the following, destinations:
- European Central Bank reference-rate feed — a free, public, keyless endpoint. This request carries no parameters that identify you or your device.
- SignalDeck's delayed FX rate feed (where configured) — authenticated with an API key that identifies the app, not you personally. No request body or parameter sent to this feed carries anything user-specific.
- Apple's StoreKit / App Store endpoints — used solely to process Pro subscription purchases. Apple's own privacy policy governs this data, not ours; we never see your payment details.
3. Local Notifications
If you enable Pro alerts, notifications are scheduled entirely on-device using Apple's local notification framework. No notification content or scheduling data is sent to any server.
4. Local Storage & Offline Cache
The App caches the most recently fetched rate data on your device so it works offline between refreshes. This cache never leaves your device and is not accessible to us.
5. Third-Party Services
Beyond the network destinations listed in Section 2, the App does not integrate any third-party SDK — no analytics, no crash reporting, no advertising network, no social login.
6. Children's Privacy
The App is rated 4+ and, since it collects no personal information from any user regardless of age, poses no age-specific privacy risk. It is not directed at children and contains no features (chat, social, user-generated content) relevant to child safety.
7. Your Rights
Because FX Strength collects no personal data, there is nothing for us to access, correct, delete, or export on your behalf. Uninstalling the App removes its local on-device cache. If you subscribed to Pro, manage or cancel that subscription directly through Apple (Settings → [your name] → Subscriptions) — SignalDeck has no visibility into or control over your Apple ID data.
8. Changes to This Policy
We may update this Privacy Policy if the App's data practices change — for example, if a future version adds an optional account system. When we do, we will update the "Last updated" date at the top of this page and, for material changes, note it in the App Store "What's New" notes.
