What data we touch, and what we do with it.

Bitlink S.A.S., a Colombian company with an office at Carrera 37K #20-03, Urbanización Guatiquía, Villavicencio (Meta), is the controller of the personal data collected on this site.

For anything concerning your data, write to daacuellar@gmail.com or call +57 317 887 4802.

From the contact form: your name, your email and the message you write. Nothing more — there are no hidden fields collecting anything else.

Your IP address is used transiently, in memory, only to stop automated submissions. It is not stored in any database and it is not included in the email we receive.

Your browser stores your theme preference (light or dark) on your own device. That never leaves your machine and never reaches us.

What you write in the form is used only to reply to you and, if a project comes out of it, to carry on the conversation with you.

That content — your name, your email, your message — is not used for advertising, not sold, and not used to train artificial intelligence models. Advertising measurement is a different matter and has its own section, just below.

We use the Meta (Facebook) pixel to find out whether our advertising works: how many of the people who arrive from an ad end up writing to us. To do that, Meta installs cookies in your browser and receives information about the pages you visit on this site.

We do NOT send Meta your name, your email or the text of your message: that stays with us. The pixel works with your browsing activity and the identifier Meta already uses for your account.

You can switch it off whenever you like: refuse or clear cookies in your browser, browse in private mode, or adjust your ad preferences in your Facebook or Instagram account. If you use a blocker, the pixel simply does not load and the site works the same.

The notification that you wrote is delivered through Resend, an email delivery provider acting as a processor, which only carries it to our inbox. The message itself lives on our server, as explained below.

Meta (Facebook) receives data about your browsing on this site through the pixel, to measure and target our advertising — as explained above. That exchange happens through Meta's cookies, never with what you write in the form.

Site usage statistics are measured on our own server and never leave it. Three things are stored per visit: the day, the page, and the site you arrived from if you arrived from one. No cookies, no IP address, no browser, no identifier of any kind — there is no way to attribute a visit to a person. If we ever switch on Umami (also self-hosted), it uses no cookies and stores no IP addresses either.

What you write in the form is stored in the database on our own server, not in a third-party service. We do it so that no message is lost if the email fails to send: if it only existed inside an email and that email never went out, your message would vanish without either of us noticing.

Only the people who administer the site can see it, signing in with a username and password.

We keep messages for as long as the conversation makes commercial sense. If you ask us to delete them, we delete them — and deletion is permanent, not archiving.

As the owner of your data you may: know what we hold, update it, correct it, request proof of the authorisation you gave us, be told how we use it, complain to the Superintendencia de Industria y Comercio, withdraw your authorisation and ask us to delete it. Accessing it is free.

Write to daacuellar@gmail.com saying what you need. We answer enquiries within ten business days and claims within fifteen, counted from the day we receive the request, under Ley 1581 de 2012.

We will not ask you to fill in forms or to justify the request: it is your right, not a favour.

This policy applies from the date it is published. Databases are kept for as long as the commercial relationship exists and for as long as the law requires us to keep them. If we change it, the date above will say so.
