Privacy Policy
Last updated: 2026-05-16
This app collects no personal data. Specifically:
- No analytics, no telemetry, no crash reporting. Nothing about your use of the app is sent anywhere.
- No account, no sign-in.
- No third-party SDKs. The app talks only to (a) your LED Ticker hardware over Bluetooth Low Energy, and (b) the public Open-Meteo geocoding/weather API and Finnhub stock-quotes API — and those calls are made by your LED Ticker device, not by this app. The app never makes outbound network requests on its own.
- Bluetooth permission is used solely to discover and connect to your LED Ticker device. The list of devices you've paired with is stored only on your phone (in
UserDefaults) and is never transmitted off-device. - WiFi credentials and your Finnhub API key, if you set them, are cached in your phone's
UserDefaultsand sent to your LED Ticker over Bluetooth so it can do its own fetches. The WiFi password is not persisted on the phone. - The "preset chips" on the Sign tab are stored only on your phone in
UserDefaults. They are not synced anywhere.
If you delete the app, all the above is removed from your device.
