Privacy
Updated 28 October 2026
Data we use
Email, account/device identifiers, push tokens, vehicle readings and alert settings, store purchase records, and usage/error types according to your app privacy settings. Used to provide, operate and understand the service, without advertising tracking.
Secondary credentials and retention
Your BYD secondary password is encrypted in transit and at rest and used only to read vehicle status. After monitoring access ends, it is kept for 7 more days to allow renewal, then erased. Revoke vehicle sharing in BYD at any time. Security and transaction records may be kept as necessary or legally required.
Service providers and alerts
App alerts use Apple APNs or Google FCM. Necessary providers include hosting, email and app stores. An internal admin messaging room receives operational information such as member references, order references and errors; it is not a customer alert channel.
Your choices
Request access, correction, deletion or objection at support@yenjai.online. Manage usage data in the app. Vehicle push alerts cannot reach you if notifications are denied.
App feedback
We store feedback content and the app diagnostics you choose to attach so we can respond and investigate issues.
Free launch access until 31 Dec 2026
No payment or automatic charge. Choose a plan after launch access ends to continue.
