Skip to content Del Ferro Institute B.V. is the institute for stuttering therapy and breathing training. We reach a wide audience through our website: delferromethod.com. We also send newsletters packed with inspiration and training tips. In doing so, we process personal data in various ways. We take your privacy very seriously.
Since most corporate privacy policies are drafted in incomprehensible legalese, we have outlined the key points for you in plain English. Pretty handy that we ourselves understand what we are promising you, right? Should anything remain unclear, please feel free to send us an email at info@delferromethod.com.
1. What Data Do We Process about You?
Depending on how you contact us, we process different types of data:
When you visit our website:
IP address (anonymized), click behavior, and cookie IDs.
When you read our newsletter or fill out a form:
Your name, email address, and (if provided) your phone number.
When you participate in a course or program:
Your name, address, contact details (email address and phone number for communication and reminders via email, SMS, or WhatsApp), payment details, as well as data regarding your progress, speech, and breathing.
Important:
Data concerning stuttering or respiratory complaints fall under special categories of personal data (health data). We treat this data with extra care and process it during a program solely because you explicitly give us consent upon registration, enabling us to provide you with optimal support.
2. Why and on What Basis Do We Do This?
We are not permitted to process your data without justification. Privacy legislation (GDPR) requires a valid reason for this, also referred to as a legal basis. We use your data on the basis of the following grounds:
Performance of the contract
We need your data to process your registration, conduct the course, send you necessary reminders for appointments or questionnaires (via email, SMS, or WhatsApp), and provide you with the promised aftercare.
Your explicit consent
For processing your progress and health data (your speech/breathing during training) and for placing marketing cookies, we request your active consent in advance. You can withdraw this consent at any time.
Legal obligation
The Tax Administration requires us to retain invoices and accounting records regarding payments for seven years.
Legitimate interest
To improve our service (website statistics) or to inform you about similar Del Ferro services if you are already a client.
3. Cookies and Online Marketing
Just like almost all websites, we use cookies. We use functional cookies (to ensure the website works properly) and analytical cookies (to see how we can improve the website). You do not need to grant permission for this, and we do not store full IP addresses; you remain anonymous to us.
In addition, we use tracking cookies and marketing pixels. These allow us to see which pages you visit, enabling us to display videos and show relevant advertisements on social media and in search engines. You decide whether you want this. You can refuse these marketing cookies via our cookie banner at the bottom of the website.
Your choice, at any time:
Did you give consent initially, but want to adjust it later? No problem. You can change or withdraw your cookie preferences directly at any time via the ‘Cookie settings’ link in the footer (the bottom) of our website.
Overview of our marketing and software partners:
Mailchimp
For securely sending and automating our emails and newsletters. This is also the system in which we maintain an organized record of contact details for our (prospective) participants.
Google Workspace
For our daily email exchanges (Gmail) and the secure internal storage of our documents and client files (Google Drive).
Tally
For completing our questionnaires digitally. This helps us map out your starting point and track your progress during the program. Because these forms may concern your speech or breathing, this data is protected with extra security.
Mollie
For the secure and smooth processing of the payment for your course or program. Mollie ensures that your payment details are handled via a secure connection.
Zoom
For conducting online video appointments, therapy sessions, and aftercare consultations. It is essential that we can see and hear each other clearly during breathing and speech exercises.
Reeleezee
Our online accounting software used to create invoices and maintain our statutory tax records.
Make
This is the smart software that ensures our various online systems can communicate securely with each other (for example, to automatically and flawlessly transfer data).
FastComet
Our reliable web hosting provider. They ensure that our website delferro.nl remains online and that all forms and online scheduling (via the Amelia software) run securely on our own server.
YouTube
For displaying our videos on the website. As soon as you play a video, YouTube may place cookies to analyze your viewing behavior.
Google Analytics
For anonymously analyzing and improving our website visits.
Google Ads
For displaying targeted advertisements in the Google search engine and measuring the success of our advertising campaigns.
Facebook Pixel
For displaying relevant advertisements on Facebook and Instagram following a visit to our website.
Twilio / MessageBird / Meta
For automatically sending SMS and/or WhatsApp reminders regarding your program and questionnaires.
4. Sharing with Third Parties (and Security)
We never sell or share the information we hold about you with other parties for their own commercial purposes. Your data is absolutely secure with us.
However, we do partner with systems necessary for our daily business operations, such as the marketing partners mentioned above and our administrative software. We have entered into strict ‘Data Processing Agreements’ (DPAs) with all these parties to ensure they handle your data with the same high level of security and confidentiality as we do.
An extra lock on the door
Because we work with privacy-sensitive data, we demand the highest level of security from ourselves and the software we use. All our employees log into these systems via two-factor authentication (2FA). This means that in addition to a strong password, an extra unique code (for example, via a security app on our phone) is always required to gain access. Even if someone were to guess our passwords, they could never access your data.
5. How Long Do We Retain Your Data?
We never retain your data longer than is strictly necessary or legally required:
Newsletter & email list
If you unsubscribe from our newsletter, your email address is moved to our internal blocklist (the ‘unsubscribed’ status in Mailchimp). We must retain your email address on this list to ensure, both technically and legally, that we never send you unwanted emails again. Your other marketing data and profile characteristics are erased or anonymized during this process.
Course participants & programs
We retain data regarding your training, progress, and aftercare for a maximum of 1 year after completing your program (when the agreement definitively ends), unless you give us explicit consent to retain your file longer for potential future refresher courses.
Financial administration
We are required by law (Tax Administration) to retain invoices, agreements, and payment details for 7 years.
6. Your Rights
Privacy legislation grants you a number of powerful rights. You can request us at any time to:
Provide access to the specific data we hold about you.
Correct your data if it contains an error or if something has changed.
Delete your data (insofar as we are no longer legally required to retain it).
Restrict or withdraw your consent for processing your health data or online marketing preferences.
Do you want to exercise one of your rights? Please send an email to info@delferromethod.com. We always respond to your request within 4 weeks. Should you unexpectedly disagree with the way we handle your personal data, you also have the right to lodge a complaint with the national privacy watchdog: the Dutch Data Protection Authority.
7. Final Remarks
We may amend this privacy and cookie statement from time to time if our working methods, technology, or legislation changes. The latest version is always available on this page. If you have any remaining questions after reading this statement, we would naturally love to hear from you!
