Contractual documents

Microsoft Customer Agreement and Microsoft Products and Services Data Protection Addendum dated 22 May 2026. The DPA governs data processing and incorporates the 2021 EU Standard Contractual Clauses for transfers from the EU and EEA. Microsoft 365 is generally covered by the EU Data Boundary; limited transfers and access outside that region remain possible under Microsoft's terms.

6. Contact via WhatsApp

WhatsApp Business is a voluntary additional contact channel. Email and telephone remain available alternatives. WhatsApp opens only after you select the external link; this website includes no WhatsApp widget, Meta SDK or tracking.

Use of WhatsApp may involve processing your telephone number, message content and any additional information you provide voluntarily. Contract-related enquiries are processed under Article 6(1)(b) GDPR and other enquiries under Article 6(1)(f) GDPR. WhatsApp processes data as part of its own service. According to the current WhatsApp Privacy Policy, services for users in the European Region are provided by WhatsApp Ireland Limited. Further information: WhatsApp Privacy Policy.

7. Remote support using HopToDesk

After prior arrangement, we offer remote support using HopToDesk. Merely opening our remote-support page does not connect to HopToDesk. Only when you select the external download link do you visit the provider website. MAIN42.tech does not host the application. When used, the application connects to the HopToDesk network.

With your approval, we may view screen content, device and system details and information needed to resolve your issue. Depending on the agreed task, personal data may be accessible. For ordinary support we do not establish permanent unattended access or record the session without a separate agreement. Depending on the case, legal bases may include Art. 6(1)(b) GDPR (contracts with natural persons) or Art. 6(1)(f) GDPR (legitimate interests in responding to business enquiries). Where we process personal data on behalf of a business client, we check whether an Art. 28 GDPR agreement is required.

HopToDesk is provided by Begonia Holdings LLC (USA). According to the provider, its network handles connection/device identifiers and IP addresses to broker sessions and may relay end-to-end encrypted session traffic. The network may include servers outside the EU. HopToDesk publishes a data processing agreement; before business use we must check that it covers the specific client and connection service. For retention, recipients and international transfers see HopToDesk’s privacy policy. Our support records are retained only as needed for the task and applicable legal requirements.

8. Cookies, analytics and external content

The current static version uses no analytics or tracking, stores no data in Local Storage and requires no consent banner. It contains no contact form, Meta Pixel, embedded WhatsApp content or external font requests. Any change requires this notice to be reassessed.

9. Your rights

Subject to the legal requirements, rights may include access, rectification, erasure, restriction, data portability and objection. You may also lodge a complaint with a competent data protection authority.

10. Transport encryption

The website is provided via HTTPS. Transport encryption protects the transmission but is not an absolute security guarantee.
