Frequently asked questions

A web app for Tesla owners and small fleets. It brings trips, charging, running costs, reminders and a logbook together in one place.

No. Viametry is an independent product of Kairyo Services s.r.o., a company in Prague, and is not owned by or affiliated with Tesla or any company connected to it. It reads your car's data through the official interface Tesla offers to independent apps.

No download: Viametry is a web app, not an App Store or Google Play app. Use it in any browser, or add it to your phone's home screen, where it opens full screen from its own icon and can send notifications. The home page shows the steps for your browser. On iPhone, notifications need it on the home screen (iOS 16.4 or newer).

Tesla Model 3, Model Y, Model S and Model X. Viametry connects through Tesla's official interface with read-only access. Your car needs current software to stream live data, and some older cars cannot stream at all; Viametry checks your car while you set it up, within the 10 free days.

Yes. The demo is the full app with sample data, so you can explore trips, charging and the logbook before connecting your own car.

You pick a comparable petrol car from 59 reference cars. Viametry prices your kilometres at the average pump price in your country each week, published by the European Commission, and sets that against your recorded charging costs.

No. Viametry's access is read-only: it can't unlock, start, drive or charge the car or change any setting, and it has no access to Autopilot or other driver assistance. It only reads what the car reports.

No. You sign in on Tesla's own page and choose there what Viametry may read. Viametry receives an access key, stored encrypted, never your password. You can disconnect in Settings or remove the access in your Tesla account at any time.

No. Viametry records what the car sends while it is awake anyway, and between drives it reads only what Tesla already has. Only if a car has sent nothing for two days (six when it is parked at home or at a saved place) does Viametry wake it once, briefly, to check that the connection still works.

A car that is asleep or offline sends its data once it is back online, so a drive can appear a few minutes after you park. If the connection drops during a drive, the map shows a short straight stretch or a break for that part.

Connections are encrypted, Tesla access keys and backups are stored encrypted, passwords only as hashes, and each person sees only what their role allows. Everything runs on Hetzner servers in the European Union, and no data is sold. The Security page has the details.

Detailed routes are kept for up to two years, or less if you set a shorter period, then only the start, end and summary of each drive. After a subscription ends you can still download everything until the end of the following calendar year; then it is deleted. Delete your account and it goes after 14 days, or at once if you choose; backups expire within a further 40 days.

Only if you connect your own assistant, such as Claude, ChatGPT or Grok. You choose the cars and whether it may only read or also make changes, and you can withdraw it at any time. Otherwise Viametry sends no data to AI services. Whether the assistant's provider may train on it is set in the assistant's own settings.

Yes. Settings → Privacy downloads everything Viametry holds about you as a spreadsheet or JSON, and the logbook exports as PDF, CSV or Excel.

Business. It includes the business and private logbook, the country profiles and the fleet tools, also for a single company car.

Czechia, Germany, Austria, the Netherlands, Poland and Slovakia, each with the fields and checks its tax rules ask for.

Viametry records the fields its country profiles cover and points out gaps. It doesn't guarantee tax acceptance or decide your deductions; your accountant reviews the records.

Drivers can use private mode, working hours apply, and drivers can see what is recorded. What managers see depends on your company policy and their role.

Yes, at any time: online without signing in, or in Settings. The plan ends with the period you have paid for and nothing more is charged. Cancel the trial before day 10 and you pay nothing; after a payment, you can ask for a full refund within 14 days. The refund policy has the details.

Payment is handled by Paddle, our reseller, at checkout. Paddle adds the VAT that applies to you and sends an invoice for every payment. Businesses can enter their company name and VAT ID at checkout.
