November 5, 2026

1. Who is protected by this privacy policy?

This privacy policy only applies to the personal data we process as data controller. It applies to the processing of our customers' personal data in connection with our telecom products and services, as well as the personal data of end-users who use these services and products through their relationship with our customer.

This policy also applies when you visit our website, fill in our contact form, subscribe to our newsletter, log in to My Wave C, take part in a survey or event, or use our products and services. The personal data of former customers and prospects is also handled and secured as carefully as possible.

2. What does 'data processing' mean and who is responsible?

2.1 Definition

By 'processing personal data' we mean any processing of data that can identify you as a natural person. The term 'processing' is broad and covers, among other things, collecting, recording, organising, storing, updating, modifying, retrieving, consulting, using, distributing or making available in any other way.

2.2 Data controller

Wave C is the controller of your personal data. For our full identification and contact details, please refer to the 'Company identification' section in our General Terms and Conditions.

3. Which personal data can we process?

3.1 Personal data of customers

We collect the personal data that allows us to contact you and to deliver and invoice our services: for example your name, address, e-mail address and phone number. If you use My Wave C, we also process your login details (e-mail address and an encrypted password). We do not process sensitive data (such as ethnic origin, political opinions or health).

3.2 Personal data of non-customers

We collect this data through our contact form, our newsletter, surveys, events and social media, in order to make businesses a relevant offer. Through the contact form we receive your name, the name of your organisation, your e-mail address and your message.

4. What do we use this personal data for?

4.1 Legal grounds

We process personal data for various purposes, and each time we only process the data that is necessary to achieve the intended purpose. Every processing activity is based on one of these legal grounds:

  • Contract: preparing, performing or terminating a quotation or contract;
  • Legal obligation: complying with legal or regulatory provisions;
  • Legitimate interest: pursuing our legitimate interests, such as securing our network and improving our services;
  • Consent: if processing your personal data is not necessary for any of the reasons above, we will always ask for your consent.

4.2 Our processing activities

  • Handling your request: using the data from the contact form to send you the information or quotation you asked for (contract).
  • My Wave C customer portal: logging you in and showing your customer details and services (contract).
  • Informing you about (new) products: sending our newsletter and special offers (consent when subscribing to the newsletter, legitimate interest for existing customers).
  • Ensuring security: camera surveillance of our server rack, located in a room with restricted access, to secure our infrastructure (legitimate interest).
  • Monitoring performance: collected feedback, surveys and service calls to improve our services (legitimate interest).
  • Legal obligations: retaining internet data and billing data as required by the government (legal obligation).

5. How do we secure your personal data?

Wave C uses a variety of technical measures to protect your personal data against unauthorised access, including passwords, hard drive encryption, firewalls and antivirus software. We use secure cloud platforms over HTTPS. In the event of a data breach, you will be notified personally in the circumstances provided for by law.

6. Do we sell your data to third parties or pass it on?

We do not sell personal data to third parties without your consent, and we do not pass it on unless required by law or necessary for our services. Examples are technicians or external customer service staff acting on our behalf.

We also use the following processors, which only process your data on our behalf:

  • Formspark (Belgium): receives the data you enter in our contact form and when subscribing to our newsletter, and forwards it to us.
  • Appwrite (data stored in Frankfurt, Germany): manages login and customer data for My Wave C.

7. How do you decide which personal data we may use for commercial purposes?

Every commercial communication from Wave C gives you the option to object to the use of your personal data for direct marketing, without having to give a reason. You can also contact us.

8. What are your privacy rights?

  • Right of access: you have the right to ask whether we process your data and to receive a copy of it.
  • Right to rectification: you can have incorrect or outdated data corrected without delay.
  • Right to erasure: you can ask us to delete your data (right to be forgotten), subject to legal restrictions.
  • Right to restriction of processing: in certain cases you can ask us to limit the use of your data.
  • Right to data portability: you can request your data in order to transfer it to another service provider.
  • Right to object: you can object to processing based on our legitimate interest, and always, without giving a reason, to direct marketing.
  • Right to withdraw consent: you have the right to withdraw your consent to the processing of your personal data at any time, without affecting the lawfulness of processing based on consent before its withdrawal.

9. Further legal provisions

  • (No) automated decision-making: Wave C does not use automated decision-making, including profiling, that produces legal effects.
  • Statutory or contractual requirement: in some cases, providing personal data is a necessary condition for entering into a contract (e.g. contact and billing details). Without this data, we cannot deliver our services.

10. How long do we keep your personal data?

We may not keep personal data longer than necessary. For invoicing or disputes, for example, this is 7 to a maximum of 10 years, because of accounting standards or legal provisions.

11. Cookie policy
