Cookie Policy
Last updated: October 19, 2026
1. What cookies are
Cookies are small text files a website stores on your device so it can remember you between visits. Some cookies are essential for the site to work; others help us understand how people arrive at the site so we can spend our marketing budget sensibly.
2. Cookies we use
The list below covers every cookie this site sets directly or via our processors. Categories follow the ePrivacy / GDPR conventions: strictly necessary cookies don’t need consent; marketing cookies do.
| Cookie | Purpose | Expiry | Category |
|---|---|---|---|
| __session, __client_uat (Clerk) | Authentication. Keeps you signed in across page loads and lets the server verify your identity. | Session and short-lived | Strictly necessary |
| trial_session | Your viewing of free episodes on this browser. Set when a free episode first plays here, it ties together our first-party record of that viewing for each show: where you stopped, so you can pick up there and find it under Continue watching; how far into the show you got; and whether you reached the sign-up screen. If you then sign up or sign in, it lets us link those records to your account. First-party only — never used for advertising. If you buy a membership without signing in, we pass it to our payment processor, Stripe, so the purchase can be linked to this browser’s viewing. A random opaque token: the cookie itself holds nothing about you (what we keep against it is described in section 2 of the Privacy Policy). | 1 year | Strictly necessary |
| matio_aid | First-party audience measurement. A random anonymous identifier we use to count unique visitors and which pages were viewed (home page, show pages, sign-up wall). First-party only — never shared with third parties, never used for advertising or cross-site tracking — so it needs no consent. | 13 months (not refreshed) | Strictly necessary |
| __stripe_mid, __stripe_sid (Stripe) | Anti-fraud fingerprinting on Stripe Checkout pages. Set by Stripe directly when you start a checkout. | Up to 1 year | Strictly necessary |
| attribution_first | First UTM source / medium / campaign you arrived from. Used to attribute paid signups to the campaign that originally introduced you to matio. | 90 days | Marketing |
| attribution_last | Most recent UTM source / medium / campaign. Used to reconcile our attribution against ad-platform dashboards. | 30 days | Marketing |
| _fbp (Meta) | Set by the Meta Pixel to identify your browser for advertising measurement and to attribute conversions to our Meta ad campaigns. Only set after you accept marketing cookies. | 90 days | Marketing |
| _fbc / fbclid (Meta) | Stores the Meta click identifier when you arrive from a Facebook or Instagram ad, so a later sign-up or subscription can be matched to that ad. Only used after you accept marketing cookies. | 90 days | Marketing |
| muxData / mux_viewer_id (Mux) | Set by Mux Data (our video provider’s analytics) to measure watch time, unique viewers and playback quality. Only used after you accept marketing cookies. | Up to 1 year | Marketing |
| ph_* (PostHog) | Set by PostHog, our product-analytics tool, to identify your browser session and measure how visitors move through the site (funnel analytics, page views, feature interactions). Session replays and heatmaps are also recorded with all inputs and text masked. Only set after you accept marketing cookies. | Up to 1 year | Marketing |
| _ga, _ga_* (Google) | Set by Google Analytics (GA4) to distinguish your browser and measure site traffic, page views and how visitors use the site. Only set after you accept marketing cookies. | Up to 2 years | Marketing |
| __oppref, __oaiq_consent (OpenAI) | Set by the ChatGPT Ads measurement pixel (OpenAI) to store the click identifier when you arrive from an ad shown in ChatGPT, so a later sign-up can be attributed to that ad, and to remember your consent choice for it. Only set after you accept marketing cookies. | Consent choice: 30 days; click id: set by OpenAI | Marketing |
We use the Meta Pixel and Meta’s Conversions API to measure how our advertising on Facebook and Instagram performs. These run only after you accept marketing cookies in the banner. When active they share a limited set of data with Meta Platforms Ireland Ltd — a hashed (SHA-256) version of your email address, your IP address, and event signals such as page views, sign-ups and subscriptions. We also use Google Analytics (GA4) to measure site traffic and how visitors use the site. It runs only after you accept marketing cookies — until then Google’s consent-mode signals are withheld — and shares usage and device data with Google Ireland Ltd. We also use the ChatGPT Ads measurement pixel to measure how our advertising in ChatGPT performs; it runs only after you accept marketing cookies and shares event signals (page views, sign-ups) with OpenAI Ireland Ltd. Our video provider Mux measures playback quality and watch time via Mux Data; like the Pixel, this runs only after you accept marketing cookies and sets a viewer identifier so we can count unique viewers. We also use PostHog (EU Cloud) for product analytics — measuring which steps of the sign-up funnel visitors reach and where they drop off. PostHog loads only after you accept marketing cookies, with autocapture disabled, session replay fully masked, and data processed on servers in the European Union (PostHog Cloud EU).
3. How to manage cookies
Wherever you are, marketing cookies are set only after you accept them in the banner, and you can turn them off at any time.
You can refuse or withdraw your consent for non-essential cookies at any time through our cookie banner — reopen it whenever you like from the “Cookie preferences” link in the site footer.
You can also delete cookies directly from your browser settings. Strictly-necessary cookies will be re-set on your next visit because the service can’t function without them.
4. Changes to this policy
We may update this Cookie Policy as we add or remove processors. The current version is dated above.
