Cookies Policy
Last updated: April 13, 2026
This Cookies Policy explains how ODYN uses cookies and similar technologies across our public website and application experience. We use the term "cookies" broadly on this page, but some items described below are stored using browser local storage, session storage, or third-party authentication technologies rather than traditional cookies.
We organize these technologies into two categories: Essential and Consent required. This page is intended to give you a clear view of what is used, why it is used, and what choices you have.
Analytics and usage measurement
These technologies help us understand how the public website is used. They are not essential and should only be enabled when a user has provided consent.
What cookies and similar technologies are
Cookies are small text files stored on your device by your browser. Similar technologies include
localStorage, sessionStorage, and storage managed by third-party identity providers.
Some of these technologies persist across browser sessions, while others are removed when the session ends.
How ODYN uses them
- To support sign-in and account security.
- To preserve essential service continuity and improve the user experience.
- To record cookie preference choices.
- To measure public website usage where analytics is enabled.

Category details
Essential
Essential technologies are used to provide services you request, such as sign-in, account security, and essential continuity needed for a consistent user experience. We do not use this category for advertising or unrelated tracking.
Consent required
Analytics technologies are used to understand how visitors use the public website. These technologies are not necessary to access the site and should only be used when consent has been provided.
Third-party technologies
ODYN uses third-party services in limited cases. These services may create or manage their own cookies or storage technologies.
- Google Analytics may be used on the public website for analytics and usage measurement.
- Firebase Authentication may use browser-managed storage and provider-controlled sign-in technologies to support authentication and account security.
Third-party providers control some aspects of their own cookies and storage behavior. As a result, exact names, durations, and domains may vary by browser, environment, and provider configuration.
Your choices
You can manage cookies and similar technologies in several ways:
- Use the ODYN cookie banner choices where available.
- Change browser settings to block, clear, or limit cookies.
- Clear local storage or session storage through your browser controls.
- Limit or revoke access to third-party accounts used for sign-in where applicable.
Blocking some essential technologies may affect sign-in, security, or other requested functionality. Blocking analytics technologies should not prevent basic access to the public website.
How often this page is updated
We may update this Cookies Policy when we change our technologies, providers, or compliance approach. The "Last updated" date at the top of this page reflects the latest revision.
