Privacy Policy — Start Lights

This Privacy Policy explains what data Start Lights (the “App”) processes. Race starts and settings work on the device without an account. The App also uses Google Firebase for anonymous analytics and crash reports. By using the App, you agree to this policy.

---

1. Summary (TL;DR)

• Race settings stay on your device (timing, skins, sound pack, and similar preferences). We do not operate a Start Lights account or our own backend for that data.
• We use Firebase Analytics (anonymous usage) and Firebase Crashlytics (crash diagnostics). Those reports go to Google. They do not include your race-timing numbers or skin choices.
• No in-app ads and no sign-up. Uninstall (or Android Clear data) removes local settings and stops new Analytics/Crashlytics events from this install.

---

2. Data we process

2.1 Data that stays on your device only

The following is stored locally and is never transmitted to us or to any third party by the App:

• Race-start settings (for example light count, hold range, skin, palette, sound pack, volume, auto-arm delay)
• Whether optional features such as Bluetooth remote input are enabled

This data is removed when you use Android Settings → Apps → Start Lights → Storage → Clear data or when you uninstall the App.

2.2 Bluetooth remote (optional)

If you pair a Bluetooth camera-shutter remote and enable Remote in Settings, the App only reacts to button presses as keyboard-style input (arm / reset). It does not read other Bluetooth device data, contacts, or files from the remote.

2.3 Permissions

• Vibration — pulse on the go signal.
• Keep the screen on / brightness — so the start lights stay visible during a sequence.
• The Android manifest includes INTERNET and ACCESS_NETWORK_STATE so Firebase and Google Play libraries can reach Google’s servers. The App does not upload race settings.

The App does not request camera, microphone, location, contacts, SMS, or storage access.

2.4 Anonymous analytics (Firebase Analytics)

To understand how the App is used, we use Google Firebase Analytics, which may collect:

• Screen views and in-app navigation events
• Approximate session duration and frequency of use
• App version, device model, OS version, language, and country (from locale / IP, not stored by us)
• A randomly generated Firebase App Instance ID per installation (typically new after Clear data or reinstall)

Analytics events do not contain race timing values, sound packs, skins, or other Settings fields. Collection is disabled in debug builds.

2.5 Crash reports (Firebase Crashlytics)

If the App crashes, we automatically collect a diagnostic report containing:

• Stack trace and exception details
• Device model, OS version, app version, available memory
• A random installation UUID (no link to your identity)

Crash data does not include Settings contents. Crash reporting is disabled in debug builds and intended for release installs.

2.6 Google Play in-app review (optional)

If you choose to rate the App, a review dialog may be shown by Google Play. That flow is operated by Google. We do not receive the contents of your review through the App.

2.7 What we do NOT collect

• No name, email, phone number, or account credentials (there is no sign-up).
• No in-app advertisements (no AdMob or similar).
• No location, photos, or contacts.

---

3. Legal basis (GDPR / UK GDPR)

Local settings stay on your device so the App can remember preferences. For analytics and crash data processed by Google, we rely on legitimate interest in maintaining and improving the App (and consent where required). You can stop new collection by uninstalling the App.

---

4. Sharing & third parties

We share data only with the providers below, only as needed to operate the App:

We do not sell or rent your data to advertisers, brokers, or any other third party.

Google Play (install, update, review) is also processed under Google’s Privacy Policy.

---

5. Your choices

• Delete local settings: Android Settings → Apps → Start Lights → Storage → Clear data, or uninstall the App.
• Stop analytics & crash reporting: uninstall the App. New events are not sent after uninstall. We do not provide a developer-operated channel to delete past analytics or crash records held by Google.
• Bluetooth remote: turn Remote off in Settings, or unpair the device in Android Bluetooth settings.

---

6. Data retention

• Local settings: until you clear the App’s data or uninstall.
• Firebase Analytics: event-level data is retained according to Google’s project default (commonly 14 months) and then aggregated.
• Firebase Crashlytics: crash records are typically retained for 90 days from the last occurrence.

---

7. Children's privacy

The App is not directed at children under 13 (or the equivalent minimum age in your jurisdiction). We do not knowingly collect data from children. If you believe a child has used the App in a way that concerns you, contact us.

---

8. Security

Local settings stay in the App’s private storage. Analytics and crash data are sent to Google over TLS. We do not operate a Start Lights cloud database. No system is perfectly secure; you use the App at your own risk.

---

9. International transfers

Firebase may process data in data centers outside your country, including the United States and the European Union. Google describes Standard Contractual Clauses and other safeguards in Firebase Privacy.

10. Changes to this policy

We may update this policy from time to time. The “Last updated” date at the top will reflect the most recent revision. Material changes will be noted in the App’s store listing or release notes.
