Cookies

We use cookies to provide and improve our service. Our approach to cookies depends on your location:

For EU/EEA Visitors

If you visit from a country covered by GDPR (EU member states, EEA countries, and the UK), you'll see a cookie consent banner on your first visit. You can choose to:

• Accept: We'll use analytics cookies to understand how you use our service and improve your experience.
• Decline: We'll switch to cookieless tracking mode, collecting only anonymized usage data without storing any cookies on your device.

For Visitors Outside the EU/EEA

If you visit from outside the EU/EEA, analytics cookies are enabled by default to provide the best experience. You can still opt out using your browser's built-in cookie controls.

Types of Cookies We Use

• Essential cookies: Required for basic functionality like authentication and session management. These are always active regardless of your consent choice.
• Analytics cookies: Used by PostHog to understand how you use our service, track errors, and improve the user experience. For EU/EEA visitors, these require your consent.

Changing Your Preferences

To change your cookie preferences, you can clear your browser's cookies and local storage for this site, then revisit to see the consent banner again (EU/EEA visitors only).

Security

We implement industry-standard security measures to protect your data, including encryption in transit and at rest, secure authentication, and regular security audits.
