Privacy Policy

How Tesrex handles website, contact and community data.

This policy explains what personal data Tesrex collects from website visitors, prospects, customers and community contributors, why we use it and how to raise a privacy request.

Last updated: 30 May 2026.

Who this policy covers.

This policy is for website visitors, prospects, customers, partners, suppliers and people who contribute to or discuss a public Tesrex project.

Tesrex Ltd is the organisation responsible for deciding how this website and business-enquiry data is used.

What personal data we collect.

The amount of personal data depends on the way you interact with Tesrex. A simple website enquiry usually needs less information than a customer engagement or technical workpack.

  • Contact and organisation details: name, role, company, work email, phone number and business address where supplied.
  • Enquiry and service context: message content, platform details, workflow description, meeting notes, project records and evidence you choose to share.
  • Website and campaign data: IP address, browser or device details, referring page, page visits, consent state, unsubscribe state and campaign engagement where those tools are enabled.
  • Community contribution data: public profile, username, issue, pull request, comment or contribution metadata where you interact with a public Tesrex GitHub project.

How we use personal data.

Tesrex uses personal data for practical business reasons connected to enquiries, customer work, service communication and website operation.

  • Respond to enquiries and decide which Tesrex route is relevant.
  • Assess requirements, prepare proposals, deliver work and maintain customer records.
  • Send service updates, launch information or business marketing where permitted.
  • Maintain unsubscribe, suppression and preference records.
  • Improve website content, forms, campaigns and customer experience.
  • Protect Tesrex systems, manage legal obligations and keep evidence of business communications.

Lawful basis.

The lawful basis depends on the context. Tesrex may rely on contract or steps before contract for customer conversations, legitimate interests for business enquiries and service improvement, consent for some marketing or optional tracking, and legal obligation where records must be kept.

Marketing and launch communication.

Tesrex may send business updates about its services, public starter kits, events or launch material where it is permitted to do so. Marketing messages should identify Tesrex and include a way to opt out.

If you opt out, Tesrex may keep a suppression record so the preference can be respected.

Cookies, analytics and similar technologies.

The website may use essential technologies needed to run the site or protect forms. Non-essential analytics, campaign tracking or similar technologies should be reflected in this policy and any consent route that applies.

Tesrex will keep cookie and analytics wording aligned with the scripts actually used on the site.

Who personal data is shared with.

Tesrex does not sell personal data. Data may be shared with suppliers and delivery partners where that is needed to run the website, respond to an enquiry, send permitted email, deliver work, maintain business records or meet a legal requirement.

Supplier categories can include website hosting, Microsoft 365, form processing, email delivery, business records, analytics, professional advisers and public code platforms where you choose to contribute.

Retention and security.

Tesrex keeps personal data only for as long as there is a practical business reason, legal reason, customer record need or suppression-record need. When records are no longer needed, they should be deleted, anonymised or reduced.

Tesrex uses reasonable technical and organisational measures to protect personal data. No internet transmission or hosted service can be guaranteed to be completely secure.

Your rights.

Under UK data protection law, individuals may have rights to access, rectify, erase, restrict, object to processing, request portability, withdraw consent and complain to the Information Commissioner’s Office.

To raise a privacy request, email solutions@tesrex.com or use the contact page and mark the enquiry as a privacy request.

AI-supported work.

If personal data is involved in AI-supported readiness, evidence-pack or workflow work, Tesrex should define the purpose, source boundary, reviewer route and customer approval path. Tesrex does not use website enquiry data to make solely automated decisions with legal or similarly significant effect.

Review basis.

This page updates the previous Tesrex privacy wording and follows the ICO emphasis on clear privacy information, cookie transparency and direct-marketing opt-out handling.
