Cookie & Tracking Policy

Effective: January 11, 2026Updated: May 11, 2026

1. What are cookies?

Cookies are small text files stored on your device. We may also use similar technologies such as local storage and authentication tokens.

2. Cookie categories

We group the cookies and similar technologies we use into the following categories:

Essential (always active)

These cookies are strictly necessary for the Services to work. They keep you signed in, maintain sessions, secure the Services, and prevent abuse. You cannot opt out of essential cookies.

  • extenshi-auth-token – JWT access token for authentication (24-hour expiration)
  • extenshi-refresh-token – JWT refresh token (7-day expiration)
  • extenshi-user-data – Basic user profile data for the UI (24-hour expiration)
  • extenshi-cookie-consent – Stores your cookie preferences (1-year expiration)

Analytics (opt-in)

These cookies help us understand how you use Extenshi so we can improve the service. They are only set after you give consent.

  • PostHog cookies and local storage – Usage analytics and product improvement. PostHog cookies are set as cross-subdomain cookies (*.extenshi.io) so your session persists across Extenshi subdomains (catalog, blog, dojo, genkan). Data is also persisted in browser local storage. If you are signed in, your analytics session is linked to your account identifier to help us understand authenticated feature usage. If you do not consent, no PostHog cookies or local storage entries are set.

Functional (opt-in)

These cookies enable enhanced functionality such as live chat support and cross-subdomain theme preferences. They are only set after you give consent.

  • extenshi-theme – Your theme preference (light/dark/system), shared across subdomains (1-year expiration)
  • Chatwoot cookies – Live chat session for customer support

3. Managing your preferences

When you first visit Extenshi, a cookie consent banner will appear. You can choose to accept all cookies, use essential cookies only, or manage your preferences by category.

Your consent choice is stored in the extenshi-cookie-consent cookie and shared across all Extenshi subdomains. To change your preferences, clear the extenshi-cookie-consent cookie from your browser and reload the page. The consent banner will reappear.

You can also manage cookies through your browser settings at any time.

4. Updates

We may update this Policy from time to time. We will publish the updated version and update the “Last updated” date.
