Confidentiality is not a page here. It is the product.
Last updated: July 2026. The short version: this website collects nothing about you, and what you share inside an engagement is protected more strictly than the law requires.
Data controller
Human Calibration is operated by ETTAI C.V., a company registered in Belgium. For anything related to your data, write to contact@human-calibration.com. A person reads and answers it.
What the website collects: nothing.
No Google Analytics, no tracking pixels, no advertising networks, no heatmaps. Your visit to this site is not measured, profiled, or stored by us.
This website sets no cookies. There is no cookie banner because there is nothing to consent to.
The site is delivered by Cloudflare, which processes technical connection data (such as IP addresses) to serve pages and protect against attacks. Typefaces are delivered by Bunny Fonts from EU servers, without logging or tracking visitors.
What we collect when you contact us.
When you email us or use a form on this website, we receive what you send: your name, your address, and the content of your message. Form submissions are delivered straight to our inbox by our email delivery provider and are not stored on this website. We use what you send to answer you and for nothing else. No newsletter, no marketing list, no sharing.
When an engagement begins, we process the data needed to run it: contact details, contractual and invoicing data, and the working material of the engagement itself, including Calibration Index Diagnostic responses and debrief notes.
Engagement confidentiality
Nothing from inside an engagement is shared with anyone. Not with your board, not with your employer, not with the organisation paying the invoice, not with anyone else. Ever, without your explicit written agreement.
Where a company funds an engagement for one of its executives, the company receives confirmation that the engagement takes place and its invoice. It receives no content, no Diagnostic results, and no assessment of the individual. This rule has no exceptions and is not negotiable at contract stage.
How long, and what you can ask.
Contractual and invoicing records are kept as long as Belgian accounting and tax law requires, then deleted. Engagement working material is kept only for the duration of the engagement plus a short follow-up period, unless you ask for earlier deletion or agree to longer retention. Correspondence is kept while the conversation is active.
Under the GDPR you can ask at any time to see the data we hold about you, correct it, delete it, restrict its use, or receive it in a portable format. One email to contact@human-calibration.com is enough. You also have the right to lodge a complaint with the Belgian Data Protection Authority at dataprotectionauthority.be, though we would rather you raise it with us first.
Processors we rely on.
A small set of providers process data on our behalf, each limited to its function: Cloudflare (website delivery and security), Bunny Fonts (typeface delivery, EU-hosted, no logging), Proton (email, end-to-end encrypted at rest), Resend (delivery of website form submissions to our inbox), and our accounting provider for legally required invoicing records. We do not sell, rent, or trade personal data. There are no advertising partners.
If this policy changes.
The date at the top changes with it. We will never quietly weaken it, and the engagement confidentiality clause above will never be weakened at all.
