Privacy policy
What we collect, why, how long we keep it, and what you can ask us to do with it. Last updated 8 November 2026.
The short version
- This site uses no cookies, no analytics and no tracking pixels.
- We only collect personal data when you send the contact sales form, and we use it to reply to you.
- The calculators run in your browser. The numbers you type never leave it.
- We do not sell your data or use it for advertising.
Who is responsible
The Growth Butler is run by TC Consulting ApS (CVR 39621363), Kystvejen 58, 4600 Køge, Denmark. We are the data controller for the personal data described here.
Questions about your data, or a request to use any of your rights: email tc@thomascilius.dk.
When you contact sales
What we collect
Your name, work email, store website, monthly ad spend (a range), team size (a range) and, if you write one, your message. We also record when the form was sent and which page referred you.
Why, and on what legal basis
To reply to your inquiry, book a call and assess whether The Growth Butler fits your store. The legal basis is steps taken at your request before a possible agreement (GDPR Article 6(1)(b)) and our legitimate interest in following up on business inquiries (Article 6(1)(f)).
Where it goes
The form sends your details to our own customer system (CRM). Nothing is stored on the website itself, and the form does not add you to any newsletter or marketing list.
How long we keep it
As long as we are in dialogue with you. If nothing comes of it, we delete your inquiry no later than 24 months after our last contact. If you become a customer, the data becomes part of the customer relationship, and accounting records are kept for the period the Danish Bookkeeping Act requires.
When you visit the site
We do not set cookies or run analytics. Like any website, our hosting provider processes technical data such as your IP address, browser type and the page you requested, in order to deliver the site and protect it against abuse. These server logs are kept for a short period by the hosting provider and are not used to identify or profile visitors. The legal basis is our legitimate interest in running a secure website (Article 6(1)(f)).
Fonts are served from our own domain, and the site loads no third-party scripts. The share buttons on articles are plain links: LinkedIn or X only receive anything if you click one, and their own privacy policies then apply.
Who processes data for us
| Processor | What for | Where |
|---|---|---|
| Vercel Inc. | Hosting the website and running the contact form | The form runs in the EU (Frankfurt). Vercel is a US company: transfers rely on the EU-US Data Privacy Framework and the EU Standard Contractual Clauses. |
| Supabase Inc. | The database behind our CRM | Stored in the EU (Ireland). Supabase is a US company: same transfer safeguards as above. |
Both act on our instructions under a data processing agreement. We make no automated decisions about you.
Your rights
You can ask for access to the data we hold about you, have it corrected or deleted, restrict or object to our use of it, and receive it in a portable format. Email tc@thomascilius.dk and we will reply within one month.
If you think we handle your data wrongly, you can complain to the Danish Data Protection Agency, Datatilsynet (datatilsynet.dk).
Changes
If we change how we handle personal data, we update this page and the date at the top.
