Privacy Policy

This Privacy Policy explains how Marsus Digital Limited collects, uses and protects personal data when you use marsus.com, contact us, request a quote, subscribe to our newsletter, interact with our analytics stack or manage your consent choices. It reflects the UK General Data Protection Regulation, the Data Protection Act 2018 and the Privacy and Electronic Communications Regulations.

2. Personal Data We Collect

  • Contact and quote data: first name, last name, email address, phone number, company name, company size and message details that you submit through our contact and quote forms.
  • Newsletter and marketing preference data: your email address, subscription status and related opt-in / opt-out records.
  • Usage and measurement data: page views, clicks, referring URL information, timestamps, browser, device, language and similar interaction data. This may be processed through PostHog Cloud EU, which is configured in cookieless mode rather than relying on traditional analytics cookies.

Depending on the integration and configuration, those events may include data you entered into the relevant form, such as your name, email address, phone number, company details or message content.
  • Technical, security and diagnostic data: IP address, request metadata, error data, performance information, console warning/error data, browser and device context, and sampled session replay information processed through Sentry.
  • Consent and preference data: the categories you accept or reject through our consent management tool, timing and history of those choices, and limited browser-side preferences such as theme or dismissed locale prompts.
  • Correspondence data: records of emails and other communications with you.

3. How We Use Personal Data

  • To respond to enquiries, prepare quotes and manage a potential or ongoing business relationship.
  • To run newsletter subscriptions and record marketing preferences.
  • To present, store and apply your consent choices.
  • To measure and improve how the site, content and conversion paths perform.
  • To detect, investigate and fix errors, performance issues and security incidents.
  • To prevent spam, misuse and unauthorised access.

4. Legal Bases

  • Contract / pre-contract steps: where you ask us to respond to an enquiry, prepare a quote or discuss services with you.
  • Legitimate interests: to run and secure our website, prevent abuse, maintain service reliability and manage business communications.
  • Consent: for newsletter communications, optional analytics or measurement technologies, non-essential session replay and similar technologies where consent is required.

5. Who We Share Personal Data With

We share personal data only where necessary and appropriate with service providers and advisers who help us operate the site and our business, including our CMS and hosting providers, cloud and email services, Google reCAPTCHA, PostHog Cloud EU, Sentry, our consent management service delivered through cookie.marsus.digital, embedded media providers where relevant, and our legal, tax or professional advisers. We may also disclose personal data where required by law or where necessary to protect our rights.

6. International Transfers

Some of our service providers may process personal data outside the United Kingdom. Where that happens, we rely on appropriate safeguards such as UK adequacy regulations, the International Data Transfer Agreement, the UK Addendum to Standard Contractual Clauses or another lawful transfer mechanism.

7. Retention

  • Contact and quote enquiries: normally up to 24 months after our last meaningful contact, unless a longer period is needed for a legal or commercial reason.
  • Newsletter records: until you unsubscribe, withdraw consent or we no longer operate the relevant list, plus limited suppression data where needed to honour your opt-out.
  • Consent and preference records: for as long as reasonably necessary to apply your choices, demonstrate compliance and manage objections or disputes.
  • Analytics and diagnostic data: only for as long as reasonably necessary to improve the service, investigate incidents, secure the site and then delete, anonymise or aggregate it.
  • Contract, transaction and statutory business records: for as long as required by applicable law.

8. Your Rights and Choice Management

Subject to the conditions and exemptions set out in data protection law, you have the right to request access to your personal data, ask for inaccurate data to be corrected, request erasure, request restriction of processing, object to processing based on legitimate interests, request portability where applicable and withdraw consent where we rely on it. You can update or withdraw your cookie and similar technology choices through the consent management tool available on the site.
