Privacy statement
This site collects as little as possible. No statistics, no advertising, no tracking. Below you can read what does happen.
Who is responsible?
Martijn Vlamings is responsible for the processing of personal data on qicheckup.nl and qicheckup.com. You can send questions about privacy to info@qicheckup.nl.
The contact form
When you use the contact form, I process your name, email address, subject and message. I use this information only to answer your question. Your message arrives in my mailbox, and you receive an automatic confirmation by email.
If you tell me something about your health in your message, that is sensitive data. I use it only to answer your question and do not share it with anyone. So please share no more than your question needs.
I keep your message for as long as our contact requires, and delete it afterwards. I do not use your details for the newsletter or any other marketing.
The newsletter
The ‘Keep me posted’ button takes you to the newsletter on chinesewisdom.net. You sign up there yourself, and the privacy statement of chinesewisdom.net applies.
Protection against misuse
To limit misuse of the form, the server keeps track of how often a message has been sent from the same IP address (at most five per hour). For this the IP address is stored only in hashed form.
The form also uses hCaptcha (Intuition Machines, Inc.) to tell real visitors from spam bots. hCaptcha is only loaded once you start filling in the form. To do its work, hCaptcha processes your IP address and information about your browser, among other things. This is based on my legitimate interest in protecting the site and my mailbox against misuse.
Cookies
This site does not place tracking or advertising cookies. Only functional cookies are used, which do not require consent:
lang: remembers your language choice (NL or EN). It is only set when you click the language button yourself, and is kept for one year.
PHPSESSID: a session cookie that is only set when you send the contact form, so the thank-you page can show your message. It disappears when you close your browser.
hCaptcha: may use technically necessary cookies or local storage on the contact page for the spam check.
Hosting and fonts
The fonts are loaded from this server, not through Google or any other external service. As with any website, the hosting provider keeps server logs, including IP addresses, for security and troubleshooting.
Your rights
You can always ask me what data I hold about you, and have it corrected or deleted. Send an email to info@qicheckup.nl. If you disagree with how I handle your data, you can file a complaint with the Dutch Data Protection Authority, the Autoriteit Persoonsgegevens.
