Privacy Policy
Short version
MAVI was built privacy-first. Your car data lives on your phone. There are no analytics, no trackers, no ads, and no third-party SDKs. What leaves your phone: (1) when you chat with MAVI AI, your message and a snapshot of current vehicle data pass through our server to an AI model and are not stored; (2) if you use your own API key instead, chat goes straight to the provider you chose and never touches our server; (3) what Apple handles for purchases.
1. What we collect
As little as possible. We operate no analytics, crash reporting, advertising, or tracking technology of any kind, and the app contains zero third-party SDKs. If you use MAVI AI (included with MAVI Pro), our server receives each chat request to pass it to the AI model, plus your App Store purchase record (a transaction identifier signed by Apple) to confirm your subscription. We keep the transaction identifier and a count of your requests so we can enforce fair-use limits. We do not store the content of your messages or your vehicle data, and we have no name, email, or account for you.
2. What stays on your device
Vehicle telemetry from your OBD adapter (speed, RPM, temperatures, battery state, fuel, trouble codes); trip history, fill-up history, and service records; photos, receipts, and purchase documents you add to the Garage Vault; your chat history and vehicle profile; and your AI API key (stored only in the iOS Keychain — encrypted, never synced to iCloud, erased with the app). All of it is stored locally. Export it anytime (Settings → Data & History → Export entire history) or delete it (Settings → Erase All My Data).
3. What leaves your device (and where it goes)
MAVI AI chat & voice (default): when you ask MAVI a question, your message, recent conversation, a brief snapshot of current vehicle data (speed, battery, fuel, temperatures, service status), and your App Store purchase record are sent over HTTPS to our server at mavi.ghb.ventures. The server confirms your subscription and forwards the request to a third-party AI model provider, which processes it under its own terms to produce the answer. Our server does not store message content. — Your own API key (optional, Settings → AI): chat is sent directly from your phone to the provider you configured (for example OpenAI, Anthropic, DeepSeek, OpenRouter, or a server you run), under that provider's privacy policy, and is never sent to GHB Ventures. — Apple: purchases and subscriptions are processed by Apple. We never see your payment details. — Apple MapKit: map images and route calculations use Apple's map service, governed by Apple's privacy policy. Nothing is sent anywhere else.
4. Location
MAVI uses your phone's location on-device to show your position, log trips, and give turn-by-turn directions. Location is never transmitted to GHB Ventures. Map rendering uses Apple's MapKit. You can deny location permission and MAVI's core OBD features still work.
5. Children
MAVI is not directed at children under 13, and purchases require you to confirm you are 18 or older. We do not knowingly collect any data from anyone — of any age.
6. Your rights (GDPR / CCPA and everyone else)
Access & portability: Settings → Data & History → Export entire history (a complete JSON bundle). Deletion: Settings → Erase All My Data wipes everything MAVI stores on your device instantly. The only record on our side is the App Store transaction identifier and request counts used for MAVI AI limits; email us to have it removed. Questions or requests: email support@ghbventures.com and we will respond within 30 days.
7. Security
If you add your own API key, it is held in the iOS Keychain with hardware-backed encryption. All AI traffic uses HTTPS. We cannot access the data stored on your device, which is protected by iOS device encryption.
8. Changes to this policy
If this policy changes, the updated version will be posted here with a new effective date. Continued use after changes means acceptance of the updated policy.
