Cookie Policy

Last Updated: 18th May 2026

This Cookie Policy explains how we use cookies and similar technologies on this website.

Cookies are small text files that are stored on your device when you visit a website. They are commonly used to make websites work, improve user experience, and provide usage analytics.

Yes, we use cookies and similar technologies for authentication, security, analytics, error monitoring, and affiliate referral tracking.

Essential authentication cookies

We use Auth.js (NextAuth) to provide secure authentication and account sessions. These cookies are necessary for logging in, maintaining sessions, and protecting user accounts from abuse or fraudulent access.

These cookies may include:

  • Session authentication tokens
  • CSRF protection tokens
  • Login state/preferences

These cookies are strictly necessary for the operation of the website.

Analytics cookies

We use Google Analytics to understand how visitors use the site and to improve performance.

Google Analytics may collect information such as:

  • Page views
  • Referrer information
  • Device and browser type
  • Approximate geographic region
  • Interaction metrics

We use a privacy-focused configuration, including IP anonymization where applicable. We do not use Google Analytics advertising features or signals for personalized advertising.

Error monitoring and security

We use Sentry to detect technical issues, monitor application stability, and diagnose errors.

Sentry may process limited technical information such as:

  • Browser and device type
  • Pages visited when an error occurs
  • Technical error logs
  • Approximate IP-derived location data

This information is used solely for debugging, security, and maintaining service reliability.

Affiliate referral cookies

If you arrive via an affiliate or referral link, we may store a referral identifier to attribute signups to the referring partner.

These cookies:

  • Do not contain directly identifying personal information
  • Are used only for referral attribution
  • Are retained for a limited period

Depending on the type of cookie or tracking technology used, we rely on different legal bases under GDPR:

  • Strictly necessary cookies (authentication and security): Article 6(1)(f) GDPR (legitimate interest) and/or necessity for providing the requested service.
  • Analytics cookies: Consent where required by applicable law.
  • Error monitoring and strictly necessary security technologies: Article 6(1)(f) GDPR (legitimate interest) and/or necessity for providing the service securely.
  • Affiliate/referral cookies: Consent where required by applicable law.

We balance this interest against your privacy rights and use a privacy-friendly analytics configuration.

Some cookies used on this website are strictly necessary for core functionality and security and therefore do not require consent.

Where required by applicable law, we will request your consent before setting non-essential cookies or tracking technologies, including certain analytics or affiliate tracking cookies.

You can also manage cookies through your browser settings:

  • Use browser settings to block or delete cookies and tracking technologies
  • Use browser privacy controls or content-blocking extensions to limit tracking technologies.

Analytics data is retained only as long as necessary for statistical purposes and system monitoring. Retention periods are determined by Google Analytics and Sentry configuration and policies. Affiliate program cookies are strictly limited to 30 days.

We use the following third-party providers:

  • Google for analytics
  • Sentry for error monitoring and application stability

These providers may process limited technical data in accordance with their own privacy policies. Some data may be processed outside your country of residence, including in the United States, subject to applicable safeguards under data protection law.

We may update this Cookie Policy from time to time to reflect legal or technical changes. Updates will be posted on this page with a revised “Last updated” date.
