Cookie policy
This page describes the cookies and similar technologies used by the DiagNow application. Tools required for operation and security remain active. PostHog and session replay are loaded only after your explicit consent.
1. What is a cookie?
A cookie is a small text file placed on your device by a website. In particular, it can remember your session and preferences and help secure certain operations.
2. Cookies we use
DiagNow uses cookies required to operate the service, payment-related cookies when you access checkout or the billing portal and, only if you agree, PostHog to measure use of the website and application. No advertising cookies are placed.

diagnow_posthog_user_id (localStorage) |
Only after consent: stores the internal user identifier to prevent events from two different accounts being linked in the same browser. | Until sign-out, rejection of PostHog or manual deletion |

3. Third-party cookies
With your consent, DiagNow uses PostHog as a product analytics tool. Session replay retains the visual structure and public text needed to understand the user journey, while masking input fields and sensitive areas, blocking media and sanitising URLs before they are sent. Users and organisations are represented by internal identifiers in analytics events; no email address is transmitted. A specialist provider may also use its own cookies when you open checkout or the billing portal. We do not place advertising cookies and do not use Google Analytics, Meta Pixel or LinkedIn Insight Tag.
4. How to manage cookies
Essential cookies cannot be disabled without making the service inoperable, for example for sign-in and form security. You can accept or reject PostHog without affecting DiagNow features, then change your choice at any time:
You can also clear all cookies and local storage from your browser settings:
