What data the app processes
EUTax does not store personal data of your store’s customers or their buyers, and it does not read your orders or your customer list. Calculations are performed on Shopify’s servers, based on the billing and shipping addresses of the cart, and the data does not leave there.
- Merchant data: when you open the app, Shopify sends us a session token that we check to know which store is accessing it. We do not store it.
- Configuration: zones, rates and tags are stored in your own Shopify store (in the app activation and in the product “Zone tax”), not on our servers. The screen language you choose is stored in your browser.
- Technical logs: the hosting provider may temporarily log IP addresses and access dates for security.
Contact form
If you write to us, we process the name, email and message you provide in order to reply. Purpose: to answer your enquiry. Legal basis: your consent. The data goes through the Web3Forms form service, which forwards it to us by email, and we keep it for as long as needed to assist you.
Shopify requests (GDPR)
We handle Shopify’s mandatory notices for access, deletion of customer data and deletion of shop data. As we do not store that data, there is nothing to deliver or delete.
Your rights
You can exercise your rights of access, rectification, erasure, objection, restriction and portability by writing to us from the Support page. You may also lodge a complaint with the Spanish Data Protection Agency (aepd.es).
