Terms of Use
This is a translation for your convenience. If there is any difference between this text and the Portuguese (pt-BR) version, the Portuguese version prevails.
These terms govern the use of the OBD Log app and service, offered by JohnJohn 3D LTDA, CNPJ 27.140.814/0001-88. By creating an account you declare that you have read and accepted these terms and the Privacy Policy.
1. What the service is
The app reads data from your vehicle through an OBD-II adapter (ELM327 or programmable ECU) and from your location (the phone's GPS or an external GPS receiver connected by Wi-Fi or Bluetooth), sends it to the server, and lets you, and the AI you connect, query the history and a rule-based analysis.
The analysis is not a diagnosis. The findings are indicative heuristics and may be wrong or incomplete. They do not replace a professional scanner or a workshop. If you suspect something is wrong with your car, see a professional. Do not make safety decisions based only on the app.
2. Your account
- You must be 18 or older and have the legal capacity to enter into contracts.
- Provide an email address of your own and keep your password secret. You are responsible for what is done with your account and with the tokens you generate.
- Tell us if you suspect unauthorized access, and change your password and revoke the AI tokens in the app.
3. Safe and responsible use
- Do not use the app while driving. Set up and check it with the car stopped. You are responsible for how you drive.
- Plug in and use the adapter at your own risk; low-quality adapters can freeze the car's ECU. The app only reads data; it does not send write commands to the vehicle.
- Record or stream video only where it is allowed. If other people or third-party license plates appear, respect their privacy and the law. When you stream live, what the camera and microphone capture is visible to whoever has the link or, on third-party platforms, to whoever the platform shows it to; you are responsible for the content.
- Use Race only in appropriate, authorized places, such as tracks and closed events. Do not chase times on public roads or break traffic laws. The ranking is a friendly comparison, with times measured by your device, and has no official value.
- Register only vehicles that are yours or that you are authorized to monitor. When you invite a driver, tell them that they will have access to the location and readings of their trips.
4. Content you publish
CAN signal definitions marked as public are visible to all users, together with your name, and can be installed and reported. You warrant that you have the right to publish them and that they do not infringe the rights of third parties. We may hide or remove content that is reported or unlawful. The same applies to the tracks you publish (name, city, description and layout) and to what appears in the Race ranking (nickname, the car you entered and times).
5. What is not allowed
- Trying to access other accounts' data, bypass limits or attack the server.
- Creating fake accounts in bulk or using the service for unlawful purposes.
- Reverse engineering the server or reselling access without authorization.
We may suspend accounts that violate these terms, notifying you whenever possible.
6. Plans and subscriptions
OBD Log has a free plan and OBD Log PRO, a monthly subscription purchased and billed through Google Play. When you subscribe, the rules below apply, in addition to the conditions shown on the purchase screen. JohnJohn 3D may offer other plans in the future, with prior notice.
- Trip history: the free plan keeps 15 days of your trips and PRO keeps 60 days. Trips older than the limit of your plan are permanently deleted from the server. To keep a trip for longer, download your data in Profile before the deadline.
- After PRO ends: the 60-day history is kept for another 30 days so that you can renew without losing data; after that, the free plan limit applies. A subscription on hold because of a payment failure, or paused in Google Play, also keeps the 60 days.
- Clear information before you pay: before the purchase we will show what the plan includes, the total price in Brazilian reais including taxes, the billing period, how it renews and how to cancel.
- Renewal and cancellation: the subscription renews automatically every month until you cancel. Cancel at any time in Google Play → Payments & subscriptions → Subscriptions → OBD Log (the "Manage on Google Play" button in the app opens that page). Cancellation applies to the following period; PRO continues until the end of the period already paid. Google Play notifies our server, and the app then shows "canceled, valid until" and the date.
- Right of withdrawal: when you subscribe away from a commercial establishment (online), you may withdraw within 7 calendar days of subscribing and get back what you paid (Brazilian Consumer Defense Code, art. 49). Purchases made through the app store also follow its refund rules.
- Changes in price or features: we will give at least 30 days' notice. If you do not agree, cancel before the renewal.
- Non-payment: Google Play tries to charge again during a grace period, and PRO continues during that time. If the payment is not resolved, the paid features are suspended and the history rules described above apply. You can still download your data and delete your account.
- Your data is not held hostage by the plan: downloading your data and deleting your account are always available, on any plan and even without payment.
- Payments: are processed by a payment provider or by the app store. We do not store card numbers. See the Privacy Policy.
- Existing users: nothing is charged without your express purchase in Google Play.
7. Availability and liability
The service is provided "as is", with no guarantee that it will work without interruptions or errors, and it may change or cease to exist, with reasonable prior notice. To the extent permitted by law, and respecting the Brazilian Consumer Defense Code, JohnJohn 3D is not liable for damage to the vehicle, or damage arising from incorrect readings, from the use of the adapter, from using the app while driving, or from decisions made by third parties (including AI assistants) based on the data.
8. Your data and the end of the account
You can download your data and delete your account at any time in the app (Profile). Deletion is permanent. The details are in the Privacy Policy.
9. Changes
We may update these terms. Relevant changes will be announced in the app and will require new acceptance to keep using it.
10. Governing law and jurisdiction
These terms are governed by Brazilian law. The courts of the consumer's place of residence are chosen to resolve disputes.
