Does Teslita qualify as a valid Fahrtenbuch for the German tax office?
Teslita captures every trip continuously from the car's own gear, GPS and odometer signals — the data points the German Finanzamt requires under §6 Abs. 1 Nr. 4 EStG: date, start and end address, route, kilometres, and purpose. Each exported report is cryptographically signed and every edit is entered into a hash-chained audit log, so an auditor can verify the document has not been altered since export.
Is this valid as a kørebog in Denmark or similar logs in other countries?
Yes. The Danish SKAT requirements for a kørebog — start and end address, odometer readings, purpose, date — are all captured automatically. The same structure satisfies the Dutch rittenregistratie, the Swedish körjournal and the Norwegian kjørebok. Whether your specific employer or tax office accepts any digital log is ultimately their decision, but Teslita gives you the evidence they are entitled to ask for.
Can I edit a trip after it's recorded?
Yes — you can correct a wrong classification, rename a location, or merge two trips that should have been one. Every edit is written to a hash-chained audit log together with a timestamp, so nothing is erased. That's what makes the final PDF defensible: an auditor can see both the corrected trip and the history of how it got there.
How is my data stored, and who can see it?
Your telemetry is stored in an EU-hosted database, scoped to your account. No third parties receive it. Your home address is only used to classify trips as "home ↔ away" and to separate home charging from public charging — it never appears on shared reports unless you deliberately include it.
Do I need to install anything in the car?
No. Teslita uses Tesla's official Fleet Telemetry stream. You approve a virtual key in the Tesla app once, and the car streams its signals directly to Teslita. There is no dongle, no OBD adapter, no always-on app on your phone.
Does it work with every Tesla model?
Any Tesla that supports Fleet Telemetry — which covers all current Model S, 3, X and Y vehicles. If your car can be paired with a third-party virtual key in the Tesla app, it works with Teslita.
What if I forget to classify a trip?
Nothing is lost. Unclassified trips are still recorded with all their detail; they simply wait for you. You can classify weeks' worth of trips in a single sitting, or batch-assign a default to anything that matches a pattern (e.g. all trips to your office address = commute).
