Privacy policy

What personal data Mecaparts processes on this website, in the Shopify app and in our projects, why, for how long, and how to exercise your rights.

Last updated: October 2026WZM Technologies EURL

Who is responsible

WZM Technologies EURL, publisher of Mecaparts, is responsible for the processing described here. For any question or request about your data, write to contact@mecaparts.app.

What this policy covers

  • The website mecaparts.app, including the blog, the documentation and the contact and audit forms. It is hosted by Vercel.
  • The Mecaparts PRO Shopify app, installed from the Shopify App Store. Its servers and database are hosted by Fly.io in Paris (European Union).
  • Projects and services we deliver on a quote.

When we build or run a store for you, you remain responsible for your own customers’ data; we act on your instructions for that data.

Data collected on the website

  • Contact and audit formsName, email, company, store address, platform, market and your message. Sent to our mailbox by email through Resend; used only to answer you and prepare a quote.
  • EmailsMessages you send to contact@mecaparts.app, received in our Google Workspace mailbox.
  • Server logsIP address, browser, pages requested and time, recorded by Vercel to deliver the site and protect it from abuse.
  • Audience measurementVercel Web Analytics counts page views without cookies and without identifying you. Google Analytics runs only if you accept analytics cookies.
  • FontsFonts are loaded from Google Fonts, which receives your IP address when the page loads.

Data processed by the Shopify app

  • Store and accountShop domain, and the name, email and language of the staff member who opens the app, as provided by Shopify.
  • Access tokensThe access token Shopify issues to the app, used to manage your products.
  • SettingsLanguage, country, enabled vehicle searches, and your TecDoc provider ID and API key.
  • ImportsThe files you import (article numbers, manufacturers, prices, quantities) and their results, so you can follow and fix imports.
  • Billing recordsPlan and usage records, needed to bill usage through Shopify.
  • Import reportsEmails we send you with the results of bulk imports, sent from our Google Workspace mailbox.
  • Storefront searchesVehicle queries from your storefront (make, model, engine, VIN, KBA or registration) pass through the app to return results. They are not linked to your customers’ identity.

The app does not request access to your customers, orders, checkouts or payments. Your products and their fitment data are stored in your Shopify store, not in our database.

InstatusPublic status page—

Where a provider processes data outside the European Union, transfers rely on the safeguards that provider offers, such as the European Commission’s standard contractual clauses or an adequacy decision.

Security

  • HTTPS on every request, for the website and the app.
  • TecDoc credentials stay on the server: they are never sent to the browser.
  • Access to the app is through Shopify’s authentication, scoped to your shop.
  • The app requests only the Shopify permissions it needs, listed on the trust page.

Shopify privacy requests

The app is subscribed to Shopify’s mandatory privacy webhooks: customer data request, customer redact and shop redact. As the app stores no data about your customers, customer requests have nothing to return or erase on our side. To have your shop’s data deleted after uninstalling, write to contact@mecaparts.app; we do it within 30 days.

Your rights

Depending on the law that applies to you, you can ask to access, correct or delete your data, object to or restrict its use, receive it in a portable format, and withdraw your consent at any time without affecting earlier processing. Write to contact@mecaparts.app; we answer within 30 days. You can also complain to the data protection authority of your country.

Cookies and similar technologies

On your first visit, a banner lets you accept or reject analytics cookies, or choose by category. Rejecting is as easy as accepting, and the site works the same either way. You can change your choice at any time from Cookie settings at the bottom of every page; we ask again after 6 months.
