Frequently Asked Questions
What happens when the free trial ends?
When the trial ends, billing starts automatically at the interval you selected (monthly or yearly). A credit card is required to start. You can cancel anytime from Settings → Manage subscription; cancellation takes effect at the next renewal (no pro-rated refund).
I own two Teslas. How is the price calculated?
Pricing is per vehicle. For two cars, monthly billing is US$12.98 (tax incl.)/month in total, or US$64.90 (tax incl.) per vehicle per year on the yearly plan.
Do I need to run my own server?
No. This is a cloud service using the official Tesla Fleet API and Fleet Telemetry, usable from a browser alone. Unlike self-hosted setups, there is no VPS contract, maintenance, or electricity cost.
Will it increase phantom drain (standby battery consumption)?
Passive recording receives Fleet Telemetry signals and avoids regular vehicle_data polling by this service. Received fields, timing and parked energy use vary with the vehicle, settings and connectivity; continued sleep or zero power use is not guaranteed. User-initiated vehicle operations and setup communication are separate.
What happens to my data if I cancel?
Cancellation takes effect at the next renewal, and you can keep using the service until then. See the Privacy Policy for how driving history and other data are handled.
What is the Battery Health Certificate?
An optional PDF containing a reference estimate of battery state of health (SOH) from recorded vehicle data. It is a one-time purchase of JPY 2,980 including tax, not an official Tesla diagnosis. A full refund revokes the certificate; previously downloaded PDFs no longer verify as valid.
