Terms of use

Version 1 · in effect since October 14, 2026

This is version 1 of this text and it may be revised; important changes will be announced by email in advance.

1. Who we are

mybyd is an independent service run by the mybyd team. Contact: support@mybyd.app.

mybyd is not made, approved or affiliated with BYD. “BYD” and the model names are trademarks of their owners, mentioned only to say which cars the service works with.

2. What the service does

mybyd reads your BYD electric car's data through the BYD account you connect (the same one as the official app) and shows history, trips, charging, costs, car health and alerts.

mybyd only reads: it does not send commands to the car.

3. Unofficial API

Reading the data relies on a BYD interface that is neither public nor documented. BYD may change or block it at any time, and the service may stop working, in whole or in part, without notice.

Using this interface may not comply with BYD's terms; by connecting your BYD account you understand and accept this risk. The data comes from BYD as BYD delivers it: it may be late, missing or wrong.

4. Your account

You must be 18 or older. You are responsible for your mybyd password. Only connect a BYD account that is yours or that you are authorised to use, and only add cars you have the right to follow. An account belongs to one person.

5. Trial and subscription

The free trial lasts 7 days and starts when you connect your first car; no card is needed.

After that, using mybyd requires a paid subscription (Plus and Pro plans, monthly or yearly), charged in advance through Stripe, our payment processor, and renewed automatically until you cancel. The final price is shown before you pay, in your country's currency. Price changes only apply from the next renewal and are announced by email at least 30 days in advance.

6. Cancellation

You can cancel whenever you like from the app's Subscription page (Stripe portal). Access continues until the end of the period already paid; there is no pro-rata refund for the current period, except where the law of your country requires it.

7. End of access

If the trial ends without a subscription, or the subscription ends, data collection stops right away and the car's data is kept for 7 more days, in case you subscribe; after that it is deleted (details in the privacy policy).

8. Acceptable use

Do not try to access other people's data, overload or attack the service, or resell it. We may suspend or close accounts that break these terms.

9. Estimates, not guarantees

Costs, consumption, range, battery and tyre health and the charging plan are estimates calculated from the car's data and your settings. They are there to inform you; they do not replace the car's dashboard, maintenance or your own judgement. Do not use mybyd for safety decisions.

10. Availability and liability

The service is provided “as is”, with no guarantee of uninterrupted operation. To the extent permitted by law, our total liability is limited to what you paid in the last 12 months. Nothing here takes away rights that your country's consumer protection law guarantees.

11. Closing your account

You can delete your account at any time under Account → Delete account; the data is deleted right away (see the privacy policy). If the service is shut down, we will let you know by email at least 30 days in advance.

12. Changes to these terms

We may update these terms; important changes are announced by email before they take effect. Continuing to use the service after that means you accept the new version.
