This agreement under Art. 28 GDPR applies between you as a business user (controller) and us (processor) wherever Dex processes personal data for you. It becomes part of the contract when you accept our terms.

1. Subject, duration, nature and purpose

The subject is checking your website, writing and checking draft improvements, recording your decisions and, if connected, analysing your Google Search Console data. Processing lasts as long as the main contract.

2. Types of data and data subjects

  • Data: content of your public pages (e.g. names, roles and contact details on team or contact pages), Search Console data, account data of your team members
  • Data subjects: your staff and team members, people named on your website, your customers and prospects where identifiable in search data

3. Our obligations

  • We process data only on your documented instructions, meaning within the functions of Dex and your settings.
  • Everyone with access is bound to confidentiality.
  • We apply the technical and organisational measures described on our Security page (Art. 32 GDPR).
  • We help you with data subject requests and your obligations under Art. 32 to 36 GDPR.
  • We notify you of personal data breaches without undue delay, at the latest within 48 hours of becoming aware.
  • When the contract ends we delete your data within 30 days, or hand it over first if you ask, unless a retention duty applies.
