Privacy

Who is responsible for the data

The author of the study, Murilo Neves de Martins, who produced it independently, with no ties to any party, candidate or campaign. Under Brazil's General Data Protection Law (LGPD, Law 13,709/2018), he is the controller: he decides what the data is used for and is responsible for it.

When you read the page

The page uses no cookies, neither for advertising nor for tracking, and has no social media buttons that report who visited. The fonts are served from the study's own address.

It stores a few of your choices in your browser, to remember them on your next visit: light or dark mode, and the charts and filters you left open. This stays on your device and is not sent to anyone; clearing the site's data in your browser clears these choices.

The study is hosted on Cloudflare, which, like any hosting service, receives the internet address (IP) of each visitor in order to deliver the page and protect it from attacks. The visit count (Cloudflare Web Analytics) uses no cookies and does not identify readers: it only shows totals, such as visits per day, country and type of device.

What you can send, and what for

A message to the author, through the “Write to the author” box in the footer

What is sent: the message and, if you wish, your name and email address. What for: so the author can read it and, if there is an email address, reply. The message goes through a form service (Web3Forms), which delivers it to the author's email without showing his address; it does not accept attachments. Messages sent directly to the author's email address, which is in the study's PDF, are handled the same way. How long it is kept: up to 12 months after the last exchange of messages; then it is deleted.

Comments, at the end of the study

What is sent: the comment, the name or nickname you choose, which appears next to it, and, if you wish, an email address, only to be notified of replies; the email address never appears on the page. What for: to publish the comment and moderate the conversation. Every comment is assessed by an artificial intelligence service, which looks at tone and behavior, never at political opinion; comments held for review are read by the author before they appear. If you write an email address or a phone number in the text, that part is hidden from others. The internet address is stored only in scrambled form, to limit the number of comments per person. How long it is kept: for as long as the study is online, or until you ask for it to be deleted.

New-edition alerts, next to the PDF

What is sent: your email address and the date of the request. What for: to send you an email when a new edition of the study comes out, with the PDF and what changed; nothing else, no advertising and no other kind of message. Every email has a link to stop receiving them, which removes the address from the list. How long it is kept: until you stop receiving them, or until the study stops having new editions.

Typed question, in “Ask the data”, under Explore

What is sent: the text of the question. What for: an artificial intelligence service reads the question only to pick which of the page's ready-made questions was asked and for which place; the answer comes from the TSE count, on the page itself. The question goes first to Cloudflare Workers AI and, once the day's free quota runs out, to Anthropic's Claude, up to a daily spending cap. The study does not store the text of the question: it stores only how many questions were asked each day and, until the end of the day, a scrambled code made from your internet address, to limit the number of questions per person. Do not type personal data in the question.

Questions to the assistant, through the “Ask the study” button in the corner of the page

What is sent: the text of the question and the earlier questions and answers in the same conversation. What for: an artificial intelligence service reads the study and writes the answer, citing the section where you can check. The question goes to gpt-oss, on Ollama, while the month's free usage lasts; after that, questions to the study stop until the following month. The study stores the question and the answer while it is online, to improve the answers and to build the frequent-questions area, which shows each question rewritten by the study, never the text of whoever asked. Stored with the question are only the date, the page language and its position in the conversation: not the internet address or anything that says who asked. That is why one person's question cannot be found later. To limit the number of questions per person, a scrambled code made from the internet address is kept until the end of the day, apart from the question. Do not type personal data in the question.

In the first three cases, an invisible protection against bots checks, without asking you anything, that the sender is a person; for typed questions, the per-person limit does that job. The legal basis for all of this is your consent (LGPD, article 7, item I): you send because you want to and can withdraw whenever you like.

What is not done

The data is not sold, not passed on to anyone and not used for advertising, election polling or campaigning, for any side. It is not combined with other databases or used to profile readers.

Who else handles the data, on behalf of the study

Only the services that make the study work, each for its own part: Cloudflare (hosting, database, protection against bots and reading typed questions), the form service behind the message box (Web3Forms), the service that sends the new-edition emails, Ollama (the assistant's answers), Anthropic (reading typed questions after Cloudflare's free quota) and the artificial intelligence service that helps moderate the comments. Some of them store data outside Brazil.

Your rights and how to exercise them

You can ask at any time to find out whether there is any data about you, to see, correct or delete it, and to withdraw your consent (LGPD, article 18). To ask, write to the author through the “Write to the author” box in the study's footer, or on LinkedIn. Requests are answered within 15 days. To stop receiving new-edition alerts, just use the link in every email. You can also complain to Brazil's National Data Protection Authority (ANPD).
