Cookie Policy

Last Updated: September 11, 2026

1. What Are Cookies?

Cookies are small text files stored on your device (computer, tablet, mobile phone) when you visit a website or use an app. They are widely used to make websites and apps work, or work more efficiently, as well as to provide information to the owners of the site.

2. How We Use Cookies

We use cookies for several purposes, including:

  • Essential Cookies: These are strictly necessary to provide you with services available through our app and to use some of its features, such as access to secure areas. Without these cookies, services you have asked for, like authentication and session management, cannot be provided.
  • Functional Cookies: These cookies are used to remember choices you make when you use our app, such as remembering your language preferences or theme settings. The purpose of these cookies is to provide you with a more personal experience and to avoid you having to re-enter your preferences every time you use the app.
  • Analytics and Performance Cookies: These cookies collect information about how you use our app, like which pages you visit and which features you use most often. This helps us to improve how our app works and to understand our user base better.
  • Marketing Cookies: We currently do not use marketing cookies. If this changes, we will update this policy.

3. Third-Party Cookies

We use a limited number of third-party services that may also set cookies on your device. These are primarily for performance and security purposes:

  • Sentry: We use Sentry for error tracking and performance monitoring to help us identify and fix bugs. Sentry may set cookies to help with session identification.
  • Axiom: We use Axiom for logging and observability, which helps us maintain the health of our systems.

These third parties have their own privacy policies and may use cookies differently. We encourage you to review their policies.

4. Your Choices and Consent

You have the right to decide whether to accept or reject cookies. For users in the European Union, we will ask for your explicit consent for non-essential cookies in accordance with GDPR.

You can manage your cookie preferences through our cookie consent banner. You can also set or amend your web browser controls to accept or refuse cookies. If you choose to reject cookies, you may still use our app though your access to some functionality and areas may be restricted.

As the means by which you can refuse cookies through your web browser controls vary from browser-to-browser, you should visit your browser's help menu for more information.

5. Cookie Retention

The length of time a cookie will stay on your device depends on whether it is a "persistent" or "session" cookie. Session cookies will only stay on your device until you stop browsing. Persistent cookies stay on your device until they expire or are deleted.

6. Policy Management and Updates

We maintain a systematic approach to managing our cookie policy to ensure compliance with evolving privacy regulations and best practices. Our cookie policy undergoes regular review and updates as needed.

Our cookie policy management includes:

  • Regular Audits: We regularly audit our cookie usage to ensure accuracy and compliance
  • Version Control: All policy updates are versioned and tracked with detailed change logs
  • User Notification: Users are informed of significant changes to our cookie practices
  • Consent Management: We maintain robust systems for managing user consent preferences
