Privacy Policy

Last updated: November 7, 2026

This policy explains what information we collect when you use Cortexpet, why we collect it, how long we keep it and what rights you have. We keep it short because we collect very little.

Who we are

Cortexpet is run by Cortexpet Limited, a company registered in England and Wales (company number 17199267). Our registered office is Office 18802, 182-184 High Street North, East Ham, London, E6 2JA, United Kingdom. We are the controller of the personal information described in this policy. You can contact us about anything in this policy at hello@cortexpet.com.

What we collect

When you take a quiz

We record that a quiz was started and finished, the answers given and the result shown. Each record uses a random number created for that visit only, and does not include your name or email address. With it, we record the country your visit came from (our hosting provider works this out from your IP address; we do not store the address itself), the name of the website that sent you to us if there was one (for example, a social network), any campaign code in the link you followed, and whether a pet name was entered (but not the name). We do not ask for your name, we do not link these records to your email address, and we do not use cookies or similar technologies to recognize you. We use these records to count how many people use our quizzes, to see which posts and links bring visitors, and to improve the quizzes. Once at least 1,000 quizzes have been finished in the past year, our home page may show that number.

Your answers stay in your browser while you take the quiz. When you close or reload the page, they are gone from your device. So that your browser's Back button takes you to the previous question, the page adds each question to the browser's history for that tab. Apart from the page address, these entries hold only the question number, its place in the quiz and a random label the page makes up for that go at the quiz, plus a note that your result is showing once you reach it. They never hold your answers, and they are not sent to us. If you tell us your cat's name, it is only used to personalize the quiz on your screen, unless you ask us to email your result (see below).

The shareable picture of your result is created in your browser. It is not sent to us, and it only goes anywhere if you choose to share or save it.

When you tell us whether your result fits

If you answer "Does this sound like your cat?" under your result, we store your answer (yes, partly or no), the quiz, the result you got and the same random number as the quiz record. It does not include your name, your cat's name or your email address.

When you enter your email address

If you choose to give us your email address, we store:

• your email address, and a random code for its unsubscribe link;
• which quiz you took and your result type;
• whether you told us your pet has shown one of the warning signs listed in the quiz, so that we send you the right information (the vet visit checklist rather than the usual result);
• your cat's name, if you gave one, so that we can personalize the email;
• the privacy notice you saw next to the email field, and that you confirmed you're 18 or older;
• whether you ticked the box to receive our tips emails, and the exact wording you agreed to;
• whether you ticked the box asking us to check in after a week, the exact wording you agreed to, when the check-in is due, a random code for its answer links, when it was sent (or why it wasn't), and whether you answered it;
• the country your visit came from, and any campaign code in the link you followed;
• the date and time, when we sent you each email, and our email service's reference for it (or the error message, if it could not be sent).

When you answer the one-week check-in

If you asked us to check in, we send you one email about a week after the quiz. When you answer it, we store your answer (better, about the same or worse), the quiz, your result type and the day. The answer is stored separately from your email address and does not include your email address, your name or your cat's name. On your sign-up we only note whether you answered (not when or what).

When you ask us to tell you when a quiz is ready

We store your email address, the quiz topic you chose, the wording you saw (including your confirmation that you're 18 or older), the country your visit came from and any campaign code in the link you followed. We use your email address only to send you one email when that quiz is ready.

When you email us

We keep your message and your email address so that we can reply.

Technical information

Like any website, our hosting provider processes technical information such as your IP address and browser type to deliver the website and keep it secure. We do not use this information to identify you, and it is kept only for a short time.

Why we use it, and our legal basis

• Sending you the result or checklist you asked for. We use your email address to provide the service you requested (contract).
• Tips emails. We send these only if you ticked the box, and you can withdraw your consent at any time using the unsubscribe link in any email or by writing to us (consent). These emails may include our own guides and product suggestions. If you told us your pet has shown a warning sign, we will not send you offers for our guides or products.
• The one-week check-in. We send this one email only if you ticked the box (consent). It contains no offers. You can withdraw your consent at any time using the unsubscribe link in any email or by writing to us. We count the answers to learn which results and tips help cats (legitimate interests).
• Telling you when a quiz is ready. We send this one email because you asked us to (consent). You can withdraw your consent at any time by writing to us.
• Understanding which posts and links bring visitors and sign-ups. We use the quiz records, and the country and campaign code stored with an email address, to see what works and decide what to make next (legitimate interests). We also use your country to show the right local vet contacts in your email.
• Improving our quizzes and showing how well results fit. We count the answers to "Does this sound like your cat?" to see which results need work. Once there are at least 100 answers in the past year, our home page may show the share of "yes" answers, together with the full counts. We keep a daily record of these totals (numbers only, nothing about any person) so we can show what the home page numbers were based on (legitimate interests).
• Keeping the website working and secure. We handle technical information to run the website and prevent abuse (legitimate interests).

We do not sell your personal information, and we do not use it for automated decisions about you.

Who we share it with

We use a small number of service providers who handle information only on our instructions:

• Vercel Inc. (United States), which hosts our website;
• Supabase Inc. (United States), which provides our database. Our database is stored in Japan;
• Resend (United States), which sends our emails;
• Google Cloud EMEA Limited (Ireland), which provides our business email (Google Workspace). Emails you send us, and our replies, may be stored on Google's servers in the United States and other countries.

When information is transferred outside the UK, it is protected by UK adequacy regulations (for example for Japan) or by the safeguards in our providers' data processing terms, such as the UK International Data Transfer Addendum to the EU Standard Contractual Clauses. We may also share information if the law requires it.

We do not take payments on this website at the moment. If we start to, we will update this policy before we do.

How long we keep it

• If you only asked for your result or checklist, we delete your email address 30 days after you enter it.
• If you agreed to receive tips emails, we keep your email address until you unsubscribe, and delete it 30 days after that.
• If you asked us to tell you when a quiz is ready, we delete your email address 30 days after we send that email, or after 12 months if the quiz is not ready by then.
• Emails you send us are kept for up to two years, unless we need them longer to deal with your request.
• Quiz records, answers to "Does this sound like your cat?" and answers to the one-week check-in do not contain your name or email address. We delete them after 13 months.

Your rights

You have the right to ask for a copy of your personal information, to have it corrected or deleted, to restrict or object to how we use it, to receive it in a portable format, and to withdraw your consent at any time. To use any of these rights, email us at hello@cortexpet.com. We will reply within one month. Wherever you live, you can use these rights in the same way.

If you are unhappy with how we handle your information, please tell us first. You also have the right to complain to the UK data protection regulator, the Information Commission's Office (ICO). Before 30 September 2026, it was called the Information Commissioner's Office. You can complain at ico.org.uk/make-a-complaint (opens in a new tab) or by calling 0303 123 1113 (from outside the UK, +44 303 123 1113).

Our social media accounts

We post on TikTok, Instagram, YouTube and Pinterest. When you follow us, comment or send us a message there, the platform handles your information under its own privacy policy. We see what you choose to share with us, such as your public profile, comments and messages, and we use it only to reply to you and to run our accounts (legitimate interests). Messages stay on the platform; we don't copy them anywhere else. We don't add anyone to our email list from social media, and we don't send marketing messages there to people who haven't asked for them.

The platforms also give us statistics about our posts, such as how many people watched them and which countries they were in. These statistics don't tell us who you are. For some of them, the platform and we may be joint controllers (Meta, for example, has a Page Insights Controller Addendum); the platform is mainly responsible for that processing, and you can use your rights with the platform directly or ask us.

If we pay to promote a post, the platform decides who sees it using its own information. We don't give the platforms any list of people, and there are no tracking pixels on our website. We only show a follower's cat in our posts with that person's permission.

Cookies and tracking

We do not use cookies or similar technologies for tracking, analytics or advertising, so we do not show a cookie banner. Campaign codes travel in the links themselves, not in cookies. Our emails do not contain tracking pixels, and we do not track whether you open them or click their links. Links in our emails carry the general code "email", which tells us a visit came from one of our emails but not from whom. If this changes, we will ask for your consent first.

Age

Our website is intended for adults aged 18 and over. Every form that asks for an email address asks you to confirm that you're 18 or older, and we don't accept the address without it. We do not knowingly collect personal information from children. If you think a child has given us their email address, please contact us and we will delete it.

Changes to this policy

We will update this page if the way we use information changes, and change the date at the top. If a change affects how we use your email address, we will tell you before it takes effect.

Our Terms of Use explain the rules for using the website.
