1. What data we collect

We only collect data that we need. We collect the following categories:

a. Data you provide to us directly

  • Identity and contact data: your name, email address, phone number, company name and any other details you enter in our contact form, when you book an introductory call, or when you email us.
  • Communication data: the content of messages you send us and our correspondence with you.

b. Data we collect automatically when you use the Service

  • Technical and usage data: your IP address, approximate location derived from it, device and browser type, operating system, referring URL, the pages you view, links you click, and the date and time of your visit.
  • Cookie and tracking data: identifiers and behavioural data set through cookies and similar technologies (see section 3). We place non-essential cookies only after you give consent through our cookie banner.

We do not intentionally collect special categories of personal data (such as health, religion or political views), and we ask you not to send us such data.

2. How we use your data, and our legal basis

We use your personal data for the following purposes, each with a legal basis under the GDPR (in the Netherlands: the AVG):

  • To respond to your enquiries and to provide and deliver our services (legal basis: performance of a contract, or our legitimate interest in answering you).
  • To send marketing and promotional communications about our services, where you have consented or where permitted for existing clients (legal basis: consent or legitimate interest; you can opt out at any time).
  • To analyse and improve our website, content and campaigns, and to measure advertising performance (legal basis: consent for non-essential analytics and advertising cookies; otherwise our legitimate interest).
  • To comply with legal obligations and to establish, exercise or defend legal claims (legal basis: legal obligation or legitimate interest).

If we want to use your data for a new purpose, we will ask for your consent first, unless the law allows otherwise.

3. Cookies and tracking technologies

Our website uses cookies and similar technologies, managed through Google Tag Manager and a cookie consent tool (CookieYes). These include functional cookies that are necessary for the site to work, and, subject to your consent, analytics and advertising cookies from the third parties named in section 4 (such as Google Analytics and Google Ads). You can give, refuse or withdraw your consent at any time via the cookie settings on our site. For details, see our Cookie Policy: https://yellify.nl/cookies/.

4. How we share your data, and with which third parties

We do not sell your personal data. We share personal data only with the following categories of recipients, and only as far as necessary:

  • Website hosting and infrastructure providers that host the Service on our behalf.
  • Analytics providers: Google (Google Analytics / GA4, Google Tag Manager) to understand and improve website usage.
  • Advertising providers: Google (Google Ads), and where used, other advertising platforms, to measure and optimise advertising.
  • Email, scheduling and CRM tools we use to communicate with you and manage enquiries.

These parties act as our processors and may only use the personal data we share for the purpose for which we provided it, under a data processing agreement, and may not keep it longer than necessary.

Advertising data processed through the Google Ads API. As part of our marketing services, we access and process advertising data through the Google Ads API on behalf of our clients (for example campaign, performance and configuration data of the advertising accounts we manage or audit). We use this data solely to provide our marketing, monitoring and reporting services to those clients, we do not use it for any unrelated purpose, and we handle it in accordance with the Google Ads API Terms of Service and applicable Google policies. We do not transfer this data to third parties except as needed to deliver the service or where required by law.

We may also disclose personal data to comply with applicable law, regulation or a valid legal request, to enforce our agreements, or in connection with a merger or acquisition, in which case your data may be transferred to the new owner.

5. International transfers

Some of our providers (such as Google) may process data outside the European Economic Area, including in the United States. Where this happens, the transfer is protected by appropriate safeguards such as the EU Standard Contractual Clauses or an adequacy decision.

6. How we protect your data

We take the security of your data seriously and apply appropriate technical and organisational measures to protect it against loss, misuse and unauthorised access or alteration. These include encryption in transit (HTTPS/TLS), access controls limiting who can access data, the use of reputable processors that maintain their own security standards, and keeping data only as long as needed. No method of transmission over the internet is fully secure, so we cannot guarantee absolute security, but we work to protect your data using reasonable measures.

7. How long we keep your data

We keep personal data only as long as necessary for the purposes described above: contact and enquiry data for as long as needed to handle your request and our relationship and to meet legal retention obligations, and analytics and advertising data for the retention periods set in the relevant tools. When data is no longer needed, we delete or anonymise it.

8. Your rights

Depending on applicable law, you have the right to access your personal data, to rectify or erase it, to restrict or object to its processing, to data portability, and to withdraw any consent you have given (without affecting processing before the withdrawal). You also have the right to lodge a complaint with the Dutch Data Protection Authority (Autoriteit Persoonsgegevens, autoriteitpersoonsgegevens.nl). To exercise your rights, email us at info@yellify.nl. We will respond in accordance with applicable law. You can opt out of marketing at any time using the unsubscribe link or by emailing us.

9. Children

The Service is not directed at children under 16, and we do not knowingly collect their personal data.

10. Changes to this Policy

We may update this Privacy Policy from time to time. We will post the revised version on this page with a new “last updated” date. We recommend reviewing this page periodically.
