Effective date: 13 November 2026
WHO WE ARE
Supertest is operated by Supertest Limited, a company registered in England
and Wales under company number 17053865 ("Supertest", "we", "us").
Supertest runs research interviews, conducted by an AI interviewer, on behalf
of organisations that want to understand their customers ("Clients"). This
notice also covers visitors to our websites and customers who use the
Supertest app.

WHAT INFORMATION WE COLLECT
- Your phone number, if you take part by phone.
- Audio of your interview, and a written transcript of it.
- Camera or screen recordings, only where an interview asks for them and you
agree.
- Your answers and anything else you choose to tell us during the interview.
- An email address, if you give one to receive a reward.
- Technical information such as device, browser and connection quality.
- A participant ID from the panel or organisation that invited you, if any.
WHY WE USE IT
- To run the interview you agreed to take part in.
- To transcribe and analyse your answers, and to share the findings with the
Client the interview was run for.
- To send you a reward, where one is offered.
- To keep our service working, secure, and to improve its quality.
We do not sell your information.
OUR LAWFUL BASIS
We rely on your consent to record and analyse your interview. You give it
before the interview starts and can withdraw it at any time by ending the
interview or contacting us. We rely on our legitimate interests to keep the
service secure and working.
WHO WE SHARE IT WITH
- The Client the interview was run for.
- Service providers who process data for us: cloud hosting and storage
(Google Cloud), speech-to-text (Deepgram), text-to-speech (Cartesia), AI
language models (Anthropic, Cerebras and OpenRouter), and communications
providers where you take part by phone.
- Authorities, where the law requires it.
Some of these providers are based outside the UK, including in the United
States. Where your information is transferred abroad, we rely on appropriate
safeguards such as the UK International Data Transfer Addendum.
VISITORS TO OUR WEBSITE AND APP
When you visit supertest.ai, try.supertest.ai or app.supertest.ai, we record
how the site is used: the pages you view, what you click, and recordings of
your session in which any text you type, and in the app all text and images,
are hidden. We use PostHog, in the European Union, to do this. We do not store
your IP address.
We only set analytics or advertising cookies if you accept them. Before you
sign in and until you choose, we count the pages you view, how far you scroll
and how long a page is open, anonymously, without storing anything on your
device or recording your session. If you reject them, we record only that you
did, and nothing more until you sign in. If you accept, a cookie holding a
random ID lets us recognise your browser across visits and across our sites
for up to six months, and if you sign up or sign in, we link those visits to
your account. We may also use advertising cookies, such as Meta's pixel, to
see which of our ads brought you to us and to improve our advertising. Meta
then receives information about your visit, which deleting your Supertest
account does not delete; you can ask Meta to delete it. We keep one cookie
that remembers your choice for six months. You can change your choice at any
time with the "Cookie settings" link at the foot of supertest.ai or
try.supertest.ai, which deletes the random ID.
If you have an account, we record what you do in the app under your account
ID, never your name or email address, together with the campaign link you
signed up through, if any. When your account is deleted, so is this
information. Session recordings are deleted after 30 days.
The sign-up and sign-in pages of app.supertest.ai are protected by Google
reCAPTCHA, through our login provider, to keep automated sign-ups out. It
sends Google information about your device and browser and how you use the
page. Google's Privacy Policy (https://policies.google.com/privacy) and Terms
of Service (https://policies.google.com/terms) apply.
CUSTOMERS
When you create an account, we collect your name, email address, password
(stored securely by our login provider, never by us in readable form), your
role and, if you give it, your company website. If you sign in with Google,
we receive your name, email address and profile picture from Google.
When you use the app, we keep what you type to set up studies, your
interview guides and settings.
Payments are handled by Stripe. We never see or store your full card
details. We keep a record of what you bought, the amount and the date.
We send account and study emails, such as email verification and study
updates, through Postmark.
We use this information to provide the service you signed up for
(contract), to measure and improve our website and product and to know which
channels bring customers (legitimate interests), to use advertising cookies
and share data with Meta (your consent, which you can withdraw), and to meet
legal and accounting obligations (legal obligation).
Service providers who process customer data for us: Google, including
Firebase (sign-in, accounts and hosting) and reCAPTCHA (keeping automated
sign-ups out), Postmark (emails), Stripe
(payments) and PostHog (analytics).
We keep account data while your account is open and delete it on request.
We keep payment and accounting records for six years, as the law requires.
HOW LONG WE KEEP IT
We keep interview recordings and transcripts for as long as the Client's
research needs them, and no longer than 24 months, unless you ask us to
delete them sooner.
YOUR RIGHTS
You have the right to ask for a copy of your information, to have it corrected
or deleted, to restrict or object to how we use it, to have it transferred,
and to withdraw your consent. Contact privacy@supertest.ai to use any of these
rights.
If you are unhappy with how we have handled your information, you can
complain to the Information Commissioner's Office: https://ico.org.uk/make-a-complaint/
