Private vehicle data for Tesla owners.

Know how your car drives, charges, and ages — with data only you can read.

The short version: Your vehicle data is encrypted with a key derived from your passphrase. We decrypt it only in memory while serving your active request, and never write plaintext to disk, logs, or backups. When you're logged out, your data is unreadable — even to us.

What you get

Drive log

Every drive, detected automatically. Distance, duration, energy used, efficiency (Wh/mi), elevation change, speed, temperature, and the route drawn on a map. Monthly and yearly totals. Tag drivers, add notes, export to CSV or GPX.

Charging log

Every charging session — home, Supercharger, destination, or other. Energy added, time elapsed, peak and average kW, charging losses. Enter your home electricity rate (time-of-use schedules supported) and we compute the cost. A Supercharger spend tracker you can cross-check against Tesla's bills.

Battery health

The degradation curve for your specific car — rated range at 100%, plotted over time. Equivalent full cycles. How long your car spends at very high or very low state-of-charge (the main things that age Tesla batteries). Lifetime energy through the pack.

Onboarding you'd expect

Sign in with your Tesla account, connect your car via Tesla's virtual key flow, done. Your encryption key is created from your passphrase at signup. We show you a twelve-word recovery phrase — save it somewhere safe, because nobody (including us) can reset it.

Why we're different

Other Tesla loggers either read everything you give them (and can leak it in a breach), monetise your data, or require you to self-host. We're the fourth option: a paid product, easy to sign up for, designed around the idea that we are the threat we protect you from. Read the full honest version on our privacy page — including the limits of the guarantee.

Pricing

$7.99 / month, with a free trial. No ads, no data resale, no "free tier paid for by your data." The subscription is the business model, full stop.
