This policy explains which cookies and similar technologies btodigital.com uses, what they are for, how long they last and how you can choose which ones you allow. The site is run by Sociedad de Profesionales Expertos SPE S.A.S. (btodigital), tax ID 900894344-9, based in Medellín, Colombia. You can write to us at info@btodigital.com.
1. What cookies are
Cookies are small files a site stores in your browser to remember information from one page to the next or between visits. Some services also use your browser's storage (local or session storage) for similar purposes. In this policy we call all of them "cookies".
2. How you choose
- The first time you visit, you see a notice. If you choose "Got it" or keep browsing, all categories are turned on. You can also choose "Reject" or "Settings" and decide category by category.
- You can change your choice at any time with the "Cookie settings" link at the bottom of every page or with the button above. We keep your choice for 180 days.
- If you reject analytics: Google Analytics still counts your visit anonymously, without storing cookies in your browser and without being able to recognise you on a later visit.
- If you reject marketing: we do not load the Meta, TikTok or ChatGPT pixels, and if you leave your details in a form we do not send them to those platforms.
- You can also delete or block cookies in your browser settings. If you block the necessary ones, some parts of the site may not work properly.
3. Necessary cookies (always on)

6. What is sent when you leave your details
When you send a form or start a WhatsApp conversation from the site, our server records the request in Google Analytics without your name or email. If you accepted marketing, it also notifies Meta, with your email, phone and name turned into an encrypted fingerprint that cannot be reversed, to measure which campaigns bring contacts, and tells ChatGPT that a sign-up happened, with no personal data. If you rejected marketing, those notifications are not sent. How we handle your personal data is described in our privacy policy (in Spanish).
