Cookie Policy

Last updated September 5, 2026

This Cookie Policy explains how Sparkclrt s.r.o. ("Company," "we," "us," and "our") uses cookies and similar technologies to recognize you when you visit our website at https://kexo.app ("Website"). It explains what these technologies are and why we use them, as well as your rights to control our use of them.

In some cases we may use cookies to collect personal information, or that becomes personal information if we combine it with other information.

What are cookies?

Cookies are small data files that are placed on your computer or mobile device when you visit a website. Cookies are widely used by website owners in order to make their websites work, or to work more efficiently, as well as to provide reporting information.

Cookies set by the website owner (in this case, Sparkclrt s.r.o.) are called "first-party cookies." Cookies set by parties other than the website owner are called "third-party cookies." Third-party cookies enable third-party features or functionality to be provided on or through the website (e.g., analytics and error monitoring). The parties that set these third-party cookies can recognize your computer both when it visits the website in question and also when it visits certain other websites.

Why do we use cookies?

We use first- and third-party cookies for several reasons. Some cookies are required for technical reasons in order for our Website to operate, and we refer to these as "essential" or "strictly necessary" cookies (for example, cookies that keep you signed in). Other cookies help us understand how the Website is used (analytics), detect and fix software errors (error monitoring), and — with your consent — measure whether our own ads led to an App Store click. We do not serve advertisements on our Website. The specific cookies we use are described in detail below.

How can I control cookies?

You have the right to decide whether to accept or reject cookies. Essential cookies cannot be rejected as they are strictly necessary to provide you with the Services. The consent banner lets you choose “Accept analytics” or “Essential only.” Non-essential analytics and session recording run only with your consent. You can change your choice in the app’s Settings under “Change cookie choices,” or use your browser controls as described below. If you choose to reject cookies, you may still use our Website though your access to some functionality and areas of our Website may be restricted.

You can also object to our analytics processing at any time by emailing us at info@sparkclrt.co.

How can I control cookies on my browser?

As the means by which you can refuse cookies through your web browser controls vary from browser to browser, you should visit your browser's help menu for more information. The following is information about how to manage cookies on the most popular browsers:

What about other tracking technologies, like web beacons?

Cookies are not the only way to recognize or track visitors to a website. We may use other, similar technologies from time to time, like web beacons (sometimes called "tracking pixels" or "clear gifs"). These are tiny graphics files that contain a unique identifier. We use them in the emails we send (through our email provider, Resend) to understand whether an email was delivered and opened, so we can measure the effectiveness of our communications. We may also use similar technologies on the Website itself to improve site performance. In many instances, these technologies are reliant on cookies to function properly, and so declining cookies will impair their functioning.

Do you serve targeted advertising?

We do not serve advertising on our Website or in our app, and we do not sell or share your personal information for targeted advertising as defined under applicable US state laws. When you arrive from an ad we run (for example in ChatGPT) and you have granted analytics consent, we use the OpenAI Ads Measurement Pixel to attribute an App Store click to that ad. That pixel may set a first-party attribution cookie. It does not receive your email, name, health data, or account identifiers.

Specific Cookies We Use

Essential Cookies (Strictly Necessary)

kexo_session — Authentication session cookie. Expires when browser session ends or after 30 days. First-party. Required for the app to function.

sb-* (Supabase) — Authentication tokens set by our authentication provider, Supabase, when you sign in (including with Google or Apple). Stored as cookies and/or in your browser's local storage. Required to keep you signed in.

Analytics and Performance Cookies

ph_* (PostHog) — Product analytics cookies used to understand how visitors interact with our Website and application, including session replay (recordings of interface interactions, with text and input content masked). Set by PostHog (EU-hosted). These cookies help us measure feature usage, page views, and interaction patterns to improve our Services. Duration varies. You can object to this analytics processing at any time by emailing us at info@sparkclrt.co, or by blocking cookies through your browser settings.

__oppref (OpenAI Ads) — First-party attribution cookie used only after you grant consent. It stores a privacy-preserving click reference from ads we run so we can measure App Store clicks. It does not include your email, name, health data, or account identifiers. Set when the OpenAI Measurement Pixel runs. Duration is determined by OpenAI's attribution window.

Functional Cookies

sentry-* (Sentry) — Error monitoring cookies used to capture session replay data when a software error occurs. These help us identify and fix bugs. Set by Sentry. Duration: session. Only active when an error is detected.
