This Data Processing Agreement (“DPA”) forms part of the Terms of Service for VAT Validator Pro EU (“the App”). It sets out our obligations as processor under Art. 28(3) GDPR when we process personal data on behalf of the merchant (the controller).
The merchant who installs the App is the controller for customer VAT validation and related store records. Tom Wilkinson, a sole trader established in Austria (Machstrasse 5, 1020 Wien, Austria), is the processor for that data.
This DPA does not apply where we act as controller (for example merchant accounts, sessions, billing/quota, and security), as described in the Privacy Policy.
The merchant instructs us by installing the App and configuring its settings (including auto tax-exempt and the merchant VAT number). We process only on those instructions unless Union or Member State law requires otherwise, in which case we inform the merchant unless the law prohibits that (Art. 28(3)(a)).
Persons authorised to process personal data are under a duty of confidentiality (Art. 28(3)(b)). We implement appropriate technical and organisational measures under Art. 32, including HTTPS in transit and restricting database access to authenticated application processes (Art. 28(3)(c)).
The merchant authorises the sub-processors listed in section 8 of the Privacy Policy. We will give at least 14 days’ notice of any intended addition or replacement, by email or in-App notice, so the merchant can object on reasonable data-protection grounds. If we cannot resolve a reasonable objection, the merchant may terminate by uninstalling the App (Art. 28(2) and 28(4)).
We assist the merchant, taking into account the nature of processing, with:
If a personal-data breach occurs in our processing as processor, we notify the merchant without undue delay after becoming aware (Art. 33(2)).
On uninstall we delete shop data and purge residual data when Shopify sends the shop-redact webhook. On a customers-redact webhook we delete that customer’s data. The merchant should export VAT audit records from the App (Validations → Export CSV) before uninstall if they need them for their own tax-retention duties (Art. 28(3)(g)).
We make available information necessary to demonstrate compliance with Art. 28 and allow audits, including inspections, conducted by the merchant or an auditor mandated by the merchant, at reasonable intervals, on reasonable notice, and in a way that does not compromise security or other merchants’ data (Art. 28(3)(h)).
Transfers outside the EEA/UK and the safeguards used are described in section 9 of the Privacy Policy.
