Who I am
Train with Gian is the business of Gian Slagter, established in Amsterdam, Dutch Chamber of Commerce number 000042073502. I am responsible for the personal data received through this website.
What details I receive
When you fill in the contact form or send me a message, I receive:
- your name;
- your email address or phone number;
- the training format you choose;
- what you write in your message.
I do not ask for medical details through this website. If you include them in your message anyway, I only use them to answer your question.
What I use them for
I use your details to answer your question and to plan an intro. I may do so because it is necessary to prepare a possible agreement with you, and because I have a legitimate interest in responding to your message.
How long I keep them
If you do not become a client, I delete your details no later than 6 months after our last contact. If you do become a client, I keep my records for as long as the law requires, usually 7 years.
Who else receives them
I do not sell your details. I only share them with companies needed to run this website and my email:
- Cloudflare, for hosting and securing the website and for the spam protection of the contact form;
- Resend, for receiving and sending email, including the messages from the contact form.
These companies may also process data outside the European Union. In that case, the safeguards required by law apply.
Cookies
This website does not use tracking, advertising or analytics cookies, which is why you do not see a cookie notice. The hosting provider does briefly keep technical data, such as your IP address and the time of your visit, to secure the website.
The Locations page links to Google Maps, and the Contact page and the bottom of every page link to Instagram. Google and Instagram only receive data if you click such a link. Their own rules apply from then on.
Spam protection
The contact form uses Cloudflare Turnstile to stop messages from bots. Turnstile checks whether you are a human. To do so, Cloudflare only processes data that is strictly necessary for this protection: your IP address and technical characteristics of your browser and connection. This only happens on the Contact page. I do not use that data myself, and Turnstile does not read what you type into the form. Cloudflare also uses the data to improve its bot detection; Cloudflare is responsible for that itself. You can read more in the Turnstile privacy addendum.
Clients and the app
If you become a client, I process more details, including information about your health, your workouts and your nutrition. You will receive separate information about this, and I ask for your consent during the intake.
Your rights
You may access, correct or delete your details. You can also object, restrict the processing and ask to transfer your details. To do so, send a message to contact@trainwithgian.com. I will respond within one month.
Filing a complaint
If we cannot resolve it together, you can file a complaint with the Dutch Data Protection Authority at autoriteitpersoonsgegevens.nl.
Changes
I may update this statement. The latest version is always on this page.
