Terms

Terms of service

Last updated 7 October 2026Covers revnote.app, the waitlist and the app

The short version. The app is in closed testing. Joining the waitlist or testing the app costs nothing and commits you to nothing. There is nothing on sale yet.

Set the app up before you move, never handle your phone while driving, and keep performance runs off public roads.

Revnote reads what your car publishes and interprets it. That is information, not a professional diagnosis. It does not replace a mechanic looking at your car, and its horsepower figures are estimates rather than measurements.

How you drive is on you. Nothing in the app is a reason to drive somewhere you should not, or faster than you are allowed to.

What these terms cover

They cover your use of revnote.app, the Revnote waitlist, and the Revnote app while it is in closed testing. By using the site, joining the list or installing the app, you accept them. The app links here from its first-launch screen, so this is the document it means.

They do not cover buying anything, because nothing is for sale yet. When there is hardware to buy there will be separate sale terms covering payment, shipping, returns and warranty. That document does not exist today, and this one does not pretend to stand in for it.

The waitlist

  • Joining is free and creates no obligation on either side. It is not an order, not a deposit, and not a reservation.
  • The price we mention, $99 to $129 CAD, is our current intention. It is not an offer, and it can change before anything goes on sale.
  • Features described on this site are what we are building, not a contractual specification. Some may change. Some may not survive.
  • We may delay the product, change it substantially, or stop work on it altogether. If that happens we will tell the list rather than going quiet.
  • We will email you when there is something to buy, and occasionally before then if there is genuine news. Every email has a one-click unsubscribe.
  • Use an email address you control. Do not sign up on someone else's behalf.

The app, in closed testing

The app is pre-release software, given to a small group of people to find out what breaks. That is not a disclaimer dressed up as a feature; it is the actual state of it.

  • It can change, break, lose a feature, or be withdrawn, without notice and without a replacement.
  • Treat anything it records as impermanent. A build can reset what is stored on your phone. If a trip matters to you, export it.
  • Testing is free, and it creates no obligation on either side. You are not committed to buying anything later, and we are not committed to selling you anything.
  • Tell us when something is wrong. That is the entire reason you have it: contact@revnote.app.
  • Everything below about safety, estimates and diagnosis applies to the test build exactly as it will to a released one.

What Revnote is, and what it is not

This is the section worth reading twice.

Revnote reads data your car already publishes through its diagnostic port, and interprets it. Interpretation means inference drawn from a limited set of signals, by software, with no eyes, no hands and no ability to hear the noise you are worried about.

  • Revnote is not a professional mechanical diagnosis and is not a substitute for an inspection by a qualified mechanic.
  • An insight that says nothing is wrong is not a clean bill of health. Plenty of faults never reach the diagnostic port at all: worn brakes, tyres, suspension, corrosion, fluid leaks, and most things you would find on a lift.
  • Explanations of fault codes describe common causes in vehicles generally. They are not a finding about the specific cause in your car.
  • Do not use Revnote as the only basis for a decision about whether a vehicle is safe to drive, for a repair you are about to pay for, or for buying or selling a car. Ask a mechanic. That is what they are for.
  • If a warning light comes on, or the car behaves in a way that worries you, treat that as more authoritative than anything the app says.

Performance and dyno figures are estimates

The horsepower and torque curves Revnote produces are calculated, not measured. The app derives them from engine speed and road speed over time, together with figures for the vehicle's mass, gearing and drivetrain loss and a model of aerodynamic drag. If those inputs are wrong for your car, or the road is not flat, or there is a headwind, the output is wrong with them.

  • These figures are not equivalent to a chassis dyno reading, and are not calibrated or certified by anyone.
  • They are not suitable as evidence of a vehicle's output in a sale, a dispute, a competition entry, a warranty claim or an insurance matter.
  • Their honest use is comparison against your own earlier runs in matched conditions.
  • Fuel consumption and cost figures are estimates too, derived from sensor data and the fuel price you enter.
  • Timing results are reported with an uncertainty range, and that range is part of the result rather than a decoration on it.

Using the app safely

This is the part that matters most, and it applies every time you use the app. Recording performance runs means accelerating hard, and we want to be direct about what that does and does not authorise.

  • Never handle your phone while driving. Start the app, mount the phone and set up what you want before you move. The app is designed to record on its own precisely so that you do not have to touch it, and no feature in it is worth a glance away from the road.
  • Obey the speed limit and every other traffic law wherever you are. Nothing in this app is permission to do otherwise.
  • Performance timing, full-throttle runs and dyno pulls belong where they are legal and safe: a closed course, a track day, or private road where you have permission. Not on a public street.
  • Do not use the app at all if using it would distract you from driving. Pull over somewhere safe, or leave it until you have stopped.
  • You are responsible for your driving, your passengers, your vehicle and everyone else on the road.
  • You are responsible for complying with any law where you are about phone use, mounting and recording in a vehicle. Those rules vary by province and country, and the app does not know where you are parked.
  • We are not responsible for tickets, licence penalties, collisions, mechanical damage or any other consequence of how a vehicle is driven while using Revnote.

The AI answers

The assistant is a language model writing about your vehicle's recorded data. Models of this kind can be wrong, can be incomplete, and can be wrong in a confident and fluent voice. Treat an answer as a starting point for a conversation with a mechanic, not as the end of one. Verify anything before you spend money or make a decision that affects safety.

Your vehicle and the adapter

The adapter connects to the standard diagnostic port fitted to your car. Reading data through that port is a passive operation, but you are responsible for using the hardware as instructed and for deciding whether to leave it connected.

Leaving any adapter plugged into a vehicle that will sit unused for a long period can drain the battery. Unplug it. Check as well whether connecting a device to the diagnostic port affects any warranty, lease or fleet agreement covering your vehicle. That is between you and whoever wrote that agreement.

Using this website

Do not attempt to break, overload or gain unauthorised access to this site, and do not submit an email address that is not yours. That is the whole list.

Ownership

The Revnote name, the site, its text and the software are ours. The data your car produces and your app records is yours, and we do not claim ownership of it.

No warranty, and limits on liability

This website, the waitlist and the test build of the app are provided as they are, without warranties of any kind, to the fullest extent the law allows. We do not promise the site or the app will be available without interruption or free of errors. Pre-release software in particular is expected to have faults.

To the extent the law allows, Revnote is not liable for indirect or consequential losses arising from your use of this site, the waitlist or the app, and our total liability for anything connected to them is limited to what you have paid us, which today is nothing.

Consumer protection law in Quebec, and elsewhere in Canada, gives you rights that a document like this cannot sign away. Where anything above conflicts with those rights, those rights win and the rest of this section still stands.

Changes to these terms

We will update this page as the product moves from a closed test to a real thing you can buy. The date at the top shows the last revision. If a change matters to people already on the list or already testing, we will email them.

Governing law

These terms are governed by the laws of the Province of Quebec and the federal laws of Canada that apply there, and the courts of Quebec have jurisdiction, without affecting any right you have to bring a claim where you live.
