Cookie Policy

Last updated 27 August 2026

This page lists every cookie Sarlo sets, what each one is for, and how long it lasts. It is a short list — we do not use advertising networks and we have no third-party tracking scripts on this site.

You can change your mind at any time using the control below.

What cookies are

A cookie is a small file a website stores on your device so it can recognise you next time. Some are essential — without them you could not stay signed in. Others are optional, and we only set those if you say yes.

The same rules apply to a few things we store on your device that are not technically cookies, such as your saved assessment progress. We have listed those too, because from your point of view the distinction does not matter much.

Your choice

Your cookie preferences

You have not made a choice yet, so we are only using strictly necessary cookies.

Choosing necessary only deletes the analytics and marketing cookies already on this device. It does not sign you out — the cookie that keeps you signed in is strictly necessary and stays.

Strictly necessary cookies are always on. We cannot run the site without them and the law does not require your consent for them. Everything else is off until you allow it, and goes away again if you withdraw permission.

If you have an account with us, we treat signing in as agreeing to our analytics cookies. You can still turn them off here, and we will respect that.

The cookies we set

CookieWhat it doesHow longType
trt_consentRemembers whether you accepted or declined non-essential cookies, so we do not ask again on every page.180 daysStrictly necessary
better-auth.session_tokenKeeps you signed in. Without it you would be signed out on every page you open.Until you sign out or the session expiresStrictly necessary
trt_attributionRecords how you first found us — for example a search, an advert or a link from another site — so we can tell which of our marketing is worth continuing.90 daysMarketing
trt_visitorA random identifier that lets us join up the pages you view into a single visit, so we can see where people get stuck. It is not linked to your name unless you later create an account.90 daysAnalytics

All of these are first-party cookies — set by us, readable only by us, and sent only to our own servers.

Other things stored on your device

WhatWhereWhat it doesHow long
trt_quiz_v1Local storageSaves your progress through the assessment — including any name, phone number and date of birth you have entered — so you can close the tab and pick up where you left off. It stays on your device until you finish the assessment or it expires.14 days
trt_attribution_pendingSession storageHolds how you found us while we wait for your cookie decision. If you accept, it moves into the trt_attribution cookie. If you decline, it is deleted.Until you close the tab
trt_journey_pendingSession storageHolds the pages you have viewed while we wait for your cookie decision, up to a limit of 50. If you accept, they are recorded. If you decline, they are deleted.Until you close the tab
Sign-in token (mobile app)Device storageKeeps you signed in to the Sarlo app. It is held in your phone's encrypted secure storage and is removed when you sign out.Until you sign out
Worth knowing: if you start our online assessment, the answers you have given — including any name, phone number and date of birth you have entered — are saved in your browser for 14 days so you can come back and finish. That stays on your device. Clearing your browsing data removes it, and so does finishing or restarting the assessment.

Third-party cookies

We do not set any. There is no Google Analytics, no Google Tag Manager, no Meta pixel, no advertising network and no session-replay tool on this site.

When you pay, our checkout uses Stripe to handle your card details securely. Stripe may set cookies of its own for fraud prevention on those pages, which is a necessary part of taking a payment safely. Their use of them is covered by Stripe's privacy policy.

The mobile app

The Sarlomobile app does not use cookies and contains no advertising or analytics SDKs. It stores one thing on your phone: a sign-in token, held in the operating system's encrypted secure storage. Signing out removes it.

Controlling cookies in your browser

You can block or delete cookies in your browser settings, and most browsers let you do it per site. Be aware that blocking all cookies will sign you out and stop you signing back in, because the sign-in cookie is one of them.

Changes to this policy

If we add or remove a cookie, we will update the tables above and change the date at the top of this page. If we ever start using a new category of cookie, we will ask for your consent again first.
