Terms of Use
Last updated 10 November 2026
These terms are the agreement between you and CarFX for using the CarFX app and website. By creating an account you accept them; if you do not agree, do not use CarFX.
1. Who we are
CarFX (“we”, “us”) can be reached at [email protected].
2. Your account
- You must be at least 16 years old to use CarFX.
- Keep your sign-in details safe. You are responsible for what happens in your account.
- Give accurate information, and keep your contact email up to date so we can reach you.
- One person per account. You may not share or sell your account.
3. Acceptable use
Use CarFX only for its purpose: tracking the costs and maintenance of vehicles you own or manage. You must not:
- break the law, or store content that infringes someone else’s rights;
- try to access other users’ data, or bypass security or plan limits;
- overload, disrupt, copy or reverse-engineer the service, or access it by automated means other than the app.
We may suspend an account that breaks these rules, and we will tell you why unless the law prevents it.
4. What CarFX is, and is not
CarFX is a record-keeping tool. Its totals, averages, cost-per-distance figures and reminders are calculated from the data you enter, so they are only as accurate as that data. They are not financial, tax, legal or mechanical advice. Reminders are a convenience: you remain responsible for your vehicle’s servicing, inspections, insurance and legal deadlines.
5. Plans and subscriptions
| Plan | Vehicles | Price |
|---|---|---|
| Free | Up to 2 | Free |
| Personal Plus | Up to 20 | Monthly subscription; the current price in your currency is shown in the app before you buy |
- Personal Plus is sold through the App Store (and Google Play on Android) and paid through your Apple or Google account. The store’s own terms also apply to the purchase.
- It renews automatically each month unless you cancel at least 24 hours before the current period ends.
- Cancel any time in your Apple ID or Google Play subscription settings (Settings → User profile → Manage subscription opens them). You keep Personal Plus until the end of the period you paid for.
- Refunds are handled by Apple or Google under their refund policies; we cannot issue them ourselves. This does not affect any right you have under consumer law.
- Price changes are announced in advance through the store, which asks for your consent where the law requires it.
6. If a subscription ends
Your data is never deleted because a subscription ends. If you have more vehicles than the Free plan allows, the first 2 in your own order stay fully usable. The others are locked: you can still view, compare, export and delete them, but not edit them or add expenses, until you subscribe again or reduce your vehicles to the Free limit.
7. Your data
The vehicles, expenses and notes you enter are yours. You give us only the permission needed to store and process them to run CarFX for you. How we handle personal data is explained in the CarFX Privacy Policy. You can export your expenses as CSV at any time, and keeping your own copy of important records is a good idea.
8. Availability and changes
We work to keep CarFX available and your data safe, but we cannot promise uninterrupted or error-free service. We may improve, change or remove features. If a change takes away something you pay for, we will tell you in advance.
9. Liability
CarFX is provided “as is”. To the extent the law allows, we are not liable for indirect or consequential losses, or for decisions you make based on figures in the app. Our total liability to you is limited to what you paid us in the 12 months before the claim. Nothing in these terms limits liability that cannot be limited by law, including for death or personal injury caused by negligence, for fraud, or your statutory rights as a consumer.
10. Ending the agreement
You can stop using CarFX and delete your account at any time in Settings → User profile → Delete CarFX account. Deleting the account does not cancel a store subscription; cancel that in your Apple or Google settings. We may end your access if you seriously or repeatedly break these terms, and we will give notice where we reasonably can.
11. Changes to these terms
We will post updated terms here and change the date at the top. For significant changes, the app will ask you to accept the new version before you continue.
