Privacy

Privacy policy

In short: this website only measures how it is used if you allow it. If you get in touch, I use your details only to handle your request. This policy follows Brazil's General Data Protection Law (LGPD, Law 13.709/2018).

This website

No cookies, no trackers and no third-party scripts (see Cookies and statistics).
A single form: the request for a first call (see below). Apart from that, contact happens through your own e-mail program, through WhatsApp or by phone.
The server keeps standard access logs (IP address, page requested, time, browser) for security and troubleshooting. They are deleted automatically after 14 days.
Hosting: servers in the European Union (Netherlands).

The contact form

Which data: your name, phone number, type of business and the time at which you prefer to be contacted.
What for: getting back to you about your request and arranging a first call. Legal basis: carrying out preliminary steps towards a possible contract, at your request (art. 7, V, of the LGPD).
How: the server forwards your request immediately to my mailbox (Proton Mail) and then deletes it from the server. If forwarding fails temporarily, the request stays on the server until it succeeds, for at most 30 days, and is then deleted.
In my mailbox I keep your request as described below under "If you get in touch".
Against abuse, the server keeps your IP address in memory for at most 24 hours, only to count how many requests arrive from the same address. It is not stored together with your request.

Ads and campaign data

If you arrived at this website through a Google ad, the page address contains a campaign number and the keyword of that ad. With that I count, per month, how many requests and clicks on the WhatsApp button each campaign and each keyword generate. That count contains no name, phone number or IP address. With a request, I send the campaign number and the keyword along in the e-mail, so I know where your request came from. This count works without cookies and without Google. The form does not store Google's click identifier (gclid).

Cookies and statistics

This website uses no cookies, no statistics tools and loads no third-party scripts. There is nothing to accept or decline. Should that ever change, you will see a notice on your first visit and this policy will be updated beforehand.

If you get in touch

If you e-mail, message or call me, I process your name, your contact details and the content of your message to answer your question and prepare a quote. Legal basis: the performance of a contract or of preliminary steps towards one. I keep this data for up to 2 years after our last contact, or for as long as the company's accounting requires (7 years for invoices, under the Dutch legislation the company is subject to).

If you are a client

For hosting and maintenance, I process the data needed for your website and for invoicing. I share it only with those indispensable for that (hosting provider, accounting firm) and never for marketing. With these parties I have agreements on security.

The WhatsApp button first passes through an address on this server, which counts how often it is clicked (without personal data) and then forwards you to WhatsApp. If you choose WhatsApp, Meta's terms also apply. If you prefer not to use it, use the form, e-mail or phone.

International transfer

Datachain Rio is a company registered in the Netherlands and the server is located in Amsterdam. Your data is therefore processed in the European Union, which has its own data protection legislation (GDPR). This transfer is necessary for the performance of the contract or of the preliminary steps you requested, under the terms of the LGPD.

Your rights

You can request confirmation of processing, access, correction, anonymization or deletion of your data, as well as information about whom it was shared with, and you can withdraw consent at any time. Write to info@datachainrio.br; I reply within 1 business day and handle the request as soon as possible. If you are not satisfied, you can lodge a complaint with Brazil's National Data Protection Authority (ANPD).

Controller

Datachain Rio, a company registered in the Netherlands (KVK 87883872), represented by Tristan, who also handles data protection matters. E-mail: info@datachainrio.br.
