Last updated: August 13, 2026 An overview of the cookies KETL Data uses and how you manage them.
Data controller
The controller for the cookies and personal data described here is KETL AS (company registration number 933 555 444), Drammensveien 123, 0277 Oslo, Norge. This cookie declaration is governed by Norwegian law, with Oslo tingrett as the legal venue. See the privacy policy for the full description of how personal data is processed.
What are cookies?
Cookies are small text files stored in your browser when you visit a website. They are used to remember preferences, keep you signed in and give us insight into how the service is used.
We use essential and functional cookies, and — only with your consent — analytics cookies (Google Analytics 4 via Firebase, the _ga cookies in the table below). We do not use advertising or cross-site tracking cookies for profiling from Meta, Hotjar or similar. Some third parties (Sentry error tracking, PostHog product analytics) are conditional — they are set only if that integration is configured, and are listed as third parties below.
Cookies we use
__sessionEssentialKeeps you signed in after authentication. Required for the service to work.
Duration: Session (cleared when the browser closes) or 1 hour (ID token)
firebase:authUser:*EssentialStores authenticated user state in localStorage, allowing automatic re-authentication without signing in again.
Duration: Persistent (until sign-out)
ketl-consentEssentialRemembers your consent choices for non-essential cookies.
Duration: 12 months
__stripe_mid / __stripe_sidEssentialThird partyRequired for card verification (Stripe Checkout in setup mode, NOK 0 — the card is never charged) and for Stripe's fraud prevention. KETL has no self-service payment flow; Stripe is used only to confirm that you are a real user.
Duration: __stripe_mid: 1 year, __stripe_sid: session
_ga / _ga_*AnalyticsThird partyWeb analytics: distinguishes users and sessions with a pseudonymised client ID. Set only after you have consented to analytics — GA4 (gtag.js) is not loaded without consent.
Duration: _ga: 24 months, _ga_<container ID>: 24 months
sentry-scFunctionalThird partyLinks error reports to a user session for debugging. Set only if the Sentry integration is enabled (SENTRY_DSN); in the default configuration error reporting goes to our own structured log and this cookie is not set.
Duration: Session
ph_* (PostHog)AnalyticsThird partyProduct analytics, funnel tracking and feature flags. Stores an anonymised user ID (distinct_id) to recognise sessions. Set only if the PostHog integration is enabled and you have consented to analytics; the default configuration uses GA4 (Firebase Analytics), not PostHog.
Duration: 12 months
Manage consent
Essential cookies cannot be disabled, as they are required for the service to work (sign-in, card verification, security).
You can disable functional and analytics cookies through the consent banner shown on your first visit, or at any time using the button below.
You can also delete all cookies in your browser settings. Note that this will sign you out of KETL Data.
Third parties
We use the following third-party providers that may set cookies:
- Google Analytics 4 (Firebase Analytics) — web analytics (only with consent; sets the _ga cookies listed above). policies.google.com/technologies/cookies
- Google / Firebase — authentication and hosting. policies.google.com/privacy
- Stripe — card verification (NOK 0 SetupIntent; the card is never charged) and fraud prevention. Card data is stored with Stripe, never with KETL. stripe.com/privacy
- Sentry — error tracking and performance monitoring (conditional: active only when the integration is configured). sentry.io/privacy/
- PostHog (cloud EU) — product analytics and funnel/feature-flag tracking (data stored in the EU, eu.posthog.com). Conditional: the default configuration uses GA4, not PostHog. posthog.com/privacy
