Privacy Policy

Last updated: May 27, 2026

1. Introduction

SlimmeTaxatie (hereafter "we" or "us") provides independent, NWWI-validated home appraisals. In order to deliver our services correctly and optimize our website, we process personal data. We respect your privacy and ensure that the personal information you provide is treated strictly confidentially and in compliance with the General Data Protection Regulation (GDPR).

2. Data We Process

When you visit our website, perform a postal code check, or submit a valuation request via our CRM calendar, we may process the following personal data:

Category Data Purpose
Contact Details First name, last name, email address, phone number Scheduling the appraiser and delivering the appraisal report.
Property Details Postal code, house number, street name, city Checking local availability of registrars and preparing the physical inspection.
Technical Details IP address, browser type, user-agent, tracking cookies Site security, fraud prevention, and conversion optimization.

3. Legal Grounds for Processing

We may only process your personal data if we have a legal basis to do so. We process your data based on the following grounds:

  • Performance of a Contract: Necessary to prepare and execute the appraisal agreement.
  • Consent: For placing marketing and tracking scripts (such as Meta Pixel) via our opt-in cookie banner.
  • Legitimate Interest: For functional and analytical optimization of our website, provided your privacy interests do not override ours.

4. Cookies and Tracking (GDPR Consent Mode v2)

Our website uses cookies. We distinguish between different types of cookies:

Consent Management (Consent Mode v2)

We fully respect your choices. By default, all marketing, replay, and analytical tracking scripts are strictly blocked until you explicitly grant consent via our cookie banner. You can modify your preferences at any time by clearing your browser cookies or clicking the deny button on the banner during your next session.

Microsoft Clarity & Advertising

We partner with Microsoft Clarity and Microsoft Advertising to capture how you use and interact with our website through behavioral metrics, heatmaps, and session replay to improve and market our products/services.

Website usage data is captured using first and third-party cookies and other tracking technologies to determine the popularity of products/services and online activity. Additionally, Microsoft may use this information for behavioral advertising, web analytics, and machine learning/AI training. For more information about how Microsoft collects and uses your data, visit the Microsoft Privacy Statement.

5. Security and CAPI Tracking

To optimally protect your personal data against theft or misuse, we utilize an advanced server-side tracking model (Meta Conversions API - CAPI). When lead details are submitted via our request form, your first name, last name, and email address are immediately encrypted client-side using a cryptographically secure SHA-256 hashing algorithm before transit.

These encrypted tokens are then sent via a secure API endpoint on our server. This ensures that your raw private data remains fully shielded from third-party scripts and browser extensions.

6. Retention Period

We do not store your personal details longer than strictly necessary to fulfill the purposes for which they were collected, unless a legal obligation (such as the Dutch fiscal retention obligation of 7 years for business records) requires us to preserve the data longer.

7. Sharing with Third Parties

We never sell your personal data to third parties. We share your information exclusively with parties directly involved in executing your appraisal request (such as the matched local NRVT appraiser and the NWWI validation institute) and processors acting on our behalf (such as HubSpot CRM for calendar bookings). Strict data processing agreements are in place with all these partners.

8. Your Rights

Under the GDPR, you have several rights regarding your personal data:

  • Right of access to the personal data we process about you.
  • Right to rectification or correction of inaccurate data.
  • Right to erasure (the right to be forgotten).
  • Right to restriction of processing and to object to specific processing activities.
  • Right to data portability.

You can submit a request to exercise these rights by contacting us at privacy@slimmetaxatie.nl. We will respond as quickly as possible, and at the latest within four weeks.
