Cookie Policy

Last updated: 30 August 2026

What cookies are

Cookies are small text files that websites place on your device (computer, phone, or tablet) when you visit them. They are widely used to make websites work, remember your preferences, and provide information to the site owner.

What we use

Nessa currently uses essential cookies only. We do not use advertising, marketing, or tracking cookies.

  • Session cookie (authjs.session-token): keeps you logged in while you use Nessa. This cookie is essential for the service to function.
  • No advertising or tracking cookies: we do not set any cookies for advertising, marketing, or cross-site tracking purposes.
  • PostHog analytics: our analytics provider uses localStorage for anonymous usage data, not cookies.

Third-party cookies

Third-party cookie usage on Nessa is currently minimal:

  • Stripe (payment processing): Stripe may set cookies when you visit the subscription page or complete a payment. These are essential for secure payment processing.
  • No other third-party cookies are used.

Analytics

PostHog is used for anonymous product analytics. It uses localStorage rather than cookies. No personally identifiable information from your conversations or incident records is sent to analytics.

See our Privacy Policy for details on how we handle analytics data.

Managing cookies

Most web browsers allow you to control cookies through their settings. You can usually find cookie controls in your browser's "Settings", "Preferences", or "Privacy" menu. Here are links for common browsers:

Please note that disabling essential cookies will prevent you from staying logged in to Nessa.

What happens if you disable cookies

If you disable cookies in your browser, you may need to log in each time you visit Nessa, as the session cookie will not be able to keep you authenticated between visits.

Core functionality requires the session cookie. Without it, Nessa cannot verify your identity or provide access to your account and records.

Changes to this policy

We may update this cookie policy from time to time. Any changes will be reflected in the "last updated" date at the top of this page. If we introduce new types of cookies or significantly change how we use them, we will notify you via the app.
