Terms of service

Effective date: November 15, 2026

These terms are an agreement between FitmentKit ("we", "us") and the business that installs the FitmentKit app in its Shopify store ("you"). By installing or using FitmentKit, you agree to them. If you're accepting for a company, you confirm you can bind it.

1. The service

FitmentKit is a Shopify app that lets you record which vehicles your products fit, shows shoppers whether a product fits the car they choose, checks the cart and new orders against that car, and can tag, note and hold orders whose parts don't match. It is available to Shopify stores selling parts for US vehicles. You need an active Shopify store to use it, and Shopify's own terms continue to apply to your store.

2. Plans and billing

Fees already charged are not refundable, except where the law requires otherwise or we decide to make an exception.

3. Cancellation and uninstalling

4. Fitment accuracy: you're responsible for your fitment

You are responsible for the fitment data in your store and for verifying that the parts you sell fit your customers' vehicles. FitmentKit is a tool that stores, displays and checks the fitment you approve. It does not know your parts better than you or your suppliers do.

5. Cart checks and order holds are an aid, not a guarantee

The cart check and order holds help catch mistakes. They do not guarantee that every wrong-part order is caught, and they don't replace your own checks before shipping. In particular:

6. Your data

7. Acceptable use

Don't misuse FitmentKit. That includes trying to access other stores' data, probing or overloading the service, getting around plan limits or rate limits, reverse engineering it except where the law allows, reselling it, or using it for anything unlawful.

8. Availability and changes

We work to keep FitmentKit running but don't promise uninterrupted service. We may change, add or remove features. If we remove a major feature of a paid plan you're on, we'll tell you in advance. We may update these terms; we'll post the new version here with a new effective date and, for significant changes, tell installed merchants first. Continuing to use FitmentKit after a change takes effect means you accept it.

9. Disclaimer of warranties

FitmentKit is provided "as is" and "as available". To the fullest extent the law allows, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, accuracy and non-infringement. We don't warrant that fit results, vehicle data or VIN decoding are accurate or complete.

10. Limitation of liability

To the fullest extent the law allows:

Some places don't allow some of these limits, so they apply only as far as the law permits.

11. Indemnity

You'll defend and indemnify us against third-party claims arising from your products, your fitment data, your store's sales, or your breach of these terms.

12. Suspension and termination

You can stop using FitmentKit at any time by uninstalling it. We may suspend or end your access if you breach these terms, if your use puts the service or other stores at risk, or if we stop offering FitmentKit; when we can, we'll give notice first. Sections 4, 5, 9, 10, 11 and 13 survive termination.

13. Governing law

These terms are governed by the laws of the State of Utah, USA, without regard to its conflict-of-laws rules. Any dispute will be brought in the state or federal courts located in Utah, and both parties consent to their jurisdiction.

14. General

These terms and the privacy policy are the whole agreement between us about FitmentKit. If a part is unenforceable, the rest still applies. Not enforcing a term is not a waiver. You may not transfer these terms without our consent; we may transfer them with the business. Neither party is liable for delays caused by events beyond its reasonable control.
