Privacy Policy

Privacy PolicyThis is the privacy statement of Sparki. Sparki respects the privacy of all users of its site and services and treats personal data carefully. This statement explains which data we process, for which purposes, on which legal bases, and how long we retain it. This document is version 1 and was last updated on May 1, 2026.

Our role in processing

Sparki is operated by Decoders B.V., Tragel west 55, 4507JD Schoondijke, KVK 84779179. Contact: support@sparki.app.


Sparki is controller for personal data we process for our own website, account management, billing, support, security, product improvement, and legal obligations.


For data that realtors, property professionals, or owners process in Sparki as part of customer and project workflows, Sparki acts as processor on behalf of the realtor or organisation using Sparki. That user is responsible for providing its own privacy notice or other legal information to customers, candidates, and other data subjects.


Data that gets processed

Sparki processes your data because you’re using our services or choosing to provide your data by filling out our appointment form, subscribing to our newsletter, or signing up for our service.


Below, you will find an overview of the personal data that gets processed:


  • First name and last name
  • Email address
  • Phone number
  • Address
  • IP address
  • Location
  • Internet browser and device type
  • Account, company, billing, support, and security data
  • Appointment details, messages, workflow answers, offers, requests, and project or customer interaction data
  • Documents and files uploaded by customers, candidates, realtors, or other users

Purposes and legal bases

For account management, access to the service, appointments, project delivery, billing, and service messages, we process personal data to perform a contract or to take steps at your request before entering into a contract.


For support, security, fraud prevention, troubleshooting, product improvement, and privacy-friendly analytics, we process data based on our legitimate interest in keeping Sparki reliable, secure, and useful.


Where we must retain or share data to comply with laws and regulations, we process that data based on a legal obligation. We send newsletters and marketing messages based on consent, unless the law allows another basis; you can unsubscribe at any time.


Personal data in realtor-customer workflows, such as customer profiles, contact details, documents, messages, appointment data, workflow answers, offers, and requests, is processed on behalf of the realtor or organisation using Sparki. That realtor or organisation determines the purpose and legal basis for the processing and must inform data subjects accordingly.


How long we hold on to your data

Sparki retains personal data no longer than necessary for the purpose for which it was collected, unless a longer retention period is legally required or needed to establish, exercise, or support legal rights.


Sparki is designed as temporary operational storage for real-estate customer workflows, not as a long-term legal, tax, Wwft, notarial, accounting, or business administration archive. Customer-uploaded documents and files are deleted 180 days after upload unless another configured retention period applies. Closed, cancelled, or completed projects are cleaned after 180 days; identifying data and linked customer interactions are deleted or anonymized while non-identifying archive shells may remain. Existing historical data may receive a 30-day grace period during rollout.


Customer profiles and contact details are deleted or anonymized after 24 months of inactivity, unless another configured retention period applies. Realtors and other Sparki users are responsible for exporting, downloading, and storing any records they must retain outside Sparki for legal, tax, Wwft, notarial, accounting, or business administration purposes before automatic cleanup. After cleanup, Sparki may keep limited non-identifying interaction history and operational metadata, while personal details and documents are removed where no longer needed.


Recipients and processors

Sparki does not sell your data. We may use trusted service providers for hosting and infrastructure, database and cache services, file storage, email and communication delivery, analytics, payments and billing, customer support, security, fraud prevention, error monitoring, and integrations that a customer enables or asks us to connect to, such as calendar, video meeting, mapping, captcha, real-estate, payment, and AI/customer workflow integrations.


These parties may process personal data only on Sparki's documented instructions and under appropriate confidentiality, security, and data-processing agreements. Where a customer enables an integration, that external provider may also process data under its own terms or as instructed by that customer.


International transfers

Some service providers or integrations may process personal data outside the European Economic Area. Where this happens, Sparki uses appropriate safeguards, such as EU Standard Contractual Clauses, adequacy decisions, or equivalent protections required by applicable data protection law.


Automated decision-making

Sparki does not use solely automated decision-making that has legal or similarly significant effects on individuals.


Cookies and similar techniques that we use

Sparki uses necessary technical and functional cookies for security, session management, login, and remembering basic settings. These cookies are needed for the website and service to work properly and are not used for advertising profiles.



For analytics, we use privacy-friendly settings or ask for consent where required. Analytics data is used to improve the operation and content of the website and service. Session cookies expire after a limited period or when you log out; analytics cookies are retained according to the settings of the analytics tool used and your cookie preferences.


Reviewing, correcting or deleting your data

You have the right to access/review, correct/rectify, delete/erase, object to processing, request restriction of processing, and ask for data portability where the AVG/GDPR allows this. You can also withdraw consent. Requests can be sent to support@sparki.app. We may ask for extra information to verify your identity; do not send an unredacted copy of your ID unless we specifically request it. If an ID is needed, we will ask you to hide details such as your photo, MRZ, document number, and social security number.


We try to respond as soon as possible and no later than four weeks. You also have the right to lodge a complaint with the Autoriteit Persoonsgegevens, the Dutch supervisory authority for privacy and data protection.


How we protect your data

Sparki takes the protection of your data seriously and takes appropriate measures to prevent misuse, loss, unauthorised access, unwanted disclosure, and unauthorised modifications. If you feel that your data is not appropriately protected or see indications of misuse, please contact us at support@sparki.app.
