App: Dynotrix — Your Pocket Dyno (Android)
Developer / Data Controller: Dynotrix / Jupiter Meta  ·  Contact: privacy@dynotrix.app

Summary: Dynotrix does not sell your data. We collect only what is needed to provide performance measurements, improve app stability, and (if you subscribe) process payments. You remain in control of your data at all times.

1. Who We Are

Dynotrix ("we", "us", "our") is a mobile application developed and operated by Jupiter Meta, headquartered at the address provided on our website. We are the data controller for personal information collected through the Dynotrix Android application and this website.

2. What Data We Collect

2.1 Sensor & Performance Data (on-device only)

Dynotrix accesses the following device sensors solely to calculate performance metrics. This data is processed entirely on your device and is never transmitted to our servers unless you explicitly export or share a run:

Run results (times, speeds, BHP, torque estimates) are stored locally on your device using SQLite. They are never uploaded to any cloud service without your explicit action.

2.2 Crash & Diagnostics Data (Firebase Crashlytics)

We use Google Firebase Crashlytics to receive crash reports. When the app crashes, the following information may be sent automatically:

Crash data is used only to diagnose and fix bugs. It does not include sensor readings or run performance data.

2.3 Analytics (Firebase Analytics)

We collect anonymised usage analytics to understand how features are used and to improve the app. This includes:

Analytics data is aggregated and does not identify you personally.

2.4 Advertising (Free tier — Google AdMob)

The free tier of Dynotrix displays banner advertisements served by Google AdMob. AdMob may use a device advertising ID to serve contextually relevant ads. You can reset or opt out of personalised ads via your Android device settings (Settings → Google → Ads). Ads are never shown on the Live Run screen to avoid distracting drivers.

Pro subscribers do not see any advertisements.

2.5 In-App Purchases & Subscription Data

If you subscribe to Dynotrix Pro, payment is processed entirely by Google Play. We receive a non-reversible transaction confirmation token and your subscription status — we never receive your full payment card details or billing address.

2.6 Contact & Beta Sign-up

If you contact us by email or sign up for the beta programme, we collect your email address and any information you voluntarily provide. This is used only to communicate with you about the beta, app updates, or your enquiry.

3. Legal Basis for Processing (GDPR / UK GDPR)

5. Data Retention

6. Your Rights

Depending on your jurisdiction, you may have the right to:

To exercise any of these rights, please email privacy@dynotrix.app. We will respond within 30 days. For complaints, you may also contact your local supervisory authority (e.g. the ICO in the UK, or the relevant EU DPA).

7. Children's Privacy

Dynotrix is not intended for use by anyone under the age of 18. We do not knowingly collect personal data from minors. If you believe a minor has provided us with personal data, please contact us immediately at privacy@dynotrix.app and we will delete it.

8. International Data Transfers

Firebase and Google services may transfer data outside your country of residence, including to the United States. Google participates in the EU-U.S. Data Privacy Framework and applies Standard Contractual Clauses where required. Our email provider operates within the EU/UK. We do not transfer your data to any country without ensuring appropriate safeguards are in place.

9. Security

We implement industry-standard security practices. Run data is stored on-device using SQLite with Android's application sandboxing. Crash and analytics data is transmitted over TLS-encrypted connections. However, no method of electronic transmission or storage is 100% secure, and we cannot guarantee absolute security.

10. Changes to This Policy

We may update this Privacy Policy from time to time. The latest version is always available at this URL and within the app under Settings → Privacy Policy. Material changes will be notified via an in-app notice. Continued use of the app after an update constitutes acceptance of the revised policy.
