Terms of Service

Last updated: June 2026

1. The service

Metercart is a Shopify app that lets your customers enter measurements on product pages and purchase at a calculated price. It is provided by Michal Bajcar ("we"). By installing the app you agree to these terms.

2. Pricing

Metercart offers a Free plan (1 calculator, 5 assigned products) and a Pro plan at $9.99 USD per month (unlimited calculators and products, widget badge removed). Billing is handled entirely by Shopify through your Shopify invoice. Plans can be changed or cancelled at any time from within Shopify; charges follow Shopify's billing cycle rules.

3. Your responsibilities

• You configure prices, formulas, and limits — verify them with the built-in preview before activating a calculator. You are responsible for the prices your store charges.
• The quantity-based cart mechanism requires the assigned product variant to be priced at the calculator's base unit price; the app warns about mismatches and inventory-tracking conflicts, and you are responsible for acting on those warnings.

4. Availability and liability

The service is provided "as is" without warranty of any kind. We aim for high availability but do not guarantee uninterrupted operation. To the maximum extent permitted by law, our total liability is limited to the fees you paid for the app in the three months preceding the claim.

5. Termination

Uninstalling the app ends the agreement. Your data is deleted per the privacy policy. We may suspend service for abuse or non-payment via Shopify.
