Privacy policy.

The short version

This is a brochure website. It has no accounts, no logins, no cookies, no analytics and no advertising or tracking technology of any kind. Nothing you type into it is sent to us. If you want to reach us you send us an email, and then we have your email — that is the whole of it.

Who is responsible

This website is operated by Fahrenheit Research, a company based in the United States, whose business address is 440 N Barranca Avenue 9029, Covina, CA 91723. We are responsible for the personal data described on this page. Because we are a United States company, anything you send us is received and held in the United States, whatever country you write from.

For anything about your personal data, including the requests described below, write to hello@f-r.co.

What this website does not do

We think the absences matter more than the presences, so they are listed first. This website:

• sets no cookies, of any kind, first or third party;
• runs no analytics — no Google Analytics, no tag manager, no Plausible, no Vercel Analytics, nothing equivalent;
• carries no advertising, tracking pixels, fingerprinting or session recording;
• has no accounts, logins or user profiles;
• embeds no third-party social or video players that could observe you;
• sends us nothing you type. No form on this site posts data to a server of ours. There is no such server.

Because there are no cookies and no tracking, there is no consent banner to click, and nothing for you to opt out of.

Do Not Track, and other opt-out signals

California law asks websites to say how they respond to a browser’s Do Not Track signal, and to global opt-out signals such as Global Privacy Control. The honest answer here is that there is nothing for them to switch off: we do not track you across this site or any other, so whether you send the signal or not, we behave the same way. We do not sell or share personal information, in the sense those words are given by California law or any other.

Your browser’s own storage

One thing is stored, and it never leaves your device. So that reloading a page or pressing Back returns you to the part you were reading rather than the top, your browser keeps a note of which section you had reached. It is held in sessionStorage under a key beginning fr-scroll:, it contains a section number and how far through it you had scrolled, and it is discarded when you close the tab.

It is not a cookie, it is not sent to us or to anyone else, it cannot identify you, and we never read it. Clearing your site data removes it; blocking storage only means pages reload at the top.

The request your browser makes anyway

This site is hosted by Vercel. As with every website, your browser has to tell the server what to send, so Vercel receives and logs the ordinary technical details of each request: your IP address, the page asked for, the time, and your browser and operating system as your browser reports them. Vercel uses these to deliver the site, to keep it available and to defend it from abuse, and acts as our processor.

We do not use these logs to build any profile of you, and we do not combine them with anything else. Our lawful basis is our legitimate interest in serving and protecting the site. Vercel operates globally, so a request may be served from, and logged in, a country outside yours, under the safeguards in our agreement with them. Vercel sets out its own retention periods in its documentation.

If you email us

The addresses on this site — research@f-r.co and press@f-r.co — are ordinary mailboxes. When you write to one, we receive what you chose to send: your name, your email address, and whatever is in your message. We use it to answer you and to carry on the conversation, on the basis of your request to be in touch and our legitimate interest in replying to enquiries about our work.

We keep business correspondence for as long as the relationship, or the law, gives us reason to, and then delete it. We do not add you to a mailing list; we have no mailing list.

The Methodal early access form

The early access questions on the Methodal page are worth describing precisely, because they look like a form that submits and they are not. Your answers stay in your browser while you move through the steps. At the last step the page opens your own email application with the answers written into a draft addressed to our research inbox. Nothing is transmitted anywhere until you press send in your own email client, and if you close the tab instead, nothing was ever collected. Once you do send it, it reaches us as the email described above.

Who else sees your data

Vercel, as the host, for the request logs described above. Also the technical staff who administer our hosting account and code repository on our behalf, who can reach those same logs. Our email provider, to carry messages you send us. Nobody else.

We do not sell personal data, we do not share it for advertising, and we do not transfer it to any other third party except where the law obliges us to.

Automated decisions, and our models

We make no automated decisions about you and carry out no profiling. The models described on this site do not run on this website and are not used on visitors. The demonstrations on the model pages are illustrations built from pre-written example data; they perform no inference and send nothing anywhere.

Your rights

There is no single United States federal privacy law that would set one list of rights for everyone reading this. Rather than recite a regime that may not apply to you, we would rather offer the same thing to everybody: ask, and we will tell you or act.

You can ask us for a copy of the personal data we hold about you, ask us to correct it or delete it, ask us to stop using it, or ask for it in a portable form. Write to hello@f-r.co and we will answer within 30 days. We will not charge you, and we will not treat you any differently for having asked.

In practice, if you have only read this website and never written to us, we almost certainly hold nothing about you at all, beyond host logs we cannot connect to your name.

We describe our work to people in the United Kingdom, Europe and India, so the UK GDPR, the EU GDPR or India’s Digital Personal Data Protection Act may apply to us in respect of you. Where one of them does, it gives you further rights — among them the right to object to processing we base on legitimate interests, and the right to complain to the data protection authority for the country where you live or work. Please tell us first if something is wrong, so we have the chance to put it right.

Children

This site is aimed at businesses and researchers, not children, and we do not knowingly collect data about children.

Changes

If we add anything that collects data — analytics, a real form, an account — we will update this page before it goes live, not after. The date below changes whenever this document does.
