Last updated: August 2026
Arca Technologies, Inc. (“Arca,” “we,” “us,” or “our”) uses cookies and similar technologies on our websites, including arca.inc and arca.science, and in connection with our services (collectively, the “Services”). This Cookie Policy explains what these technologies are, why we use them, and how you can manage your choices.
For more information about how we handle personal data, please see our Privacy Policy.
1. What are cookies?
Cookies are small text files that are placed on your computer or mobile device when you visit a website. They are widely used to make websites work or work more efficiently, as well as to provide reporting information. We also use similar technologies such as pixels, web beacons, local storage, and software development kits (SDKs).
Session-based cookies last only while your browser is open and are deleted when you close it. Persistent cookies last until you or your browser delete them or until they expire.
2. Why do we use cookies?
We use cookies and similar technologies to:
- Operate, secure, and maintain the Services;
- Understand how visitors use our websites;
- Remember your preferences and choices;
- Deliver, measure, and improve our marketing.
3. Categories of cookies we use
Strictly Necessary
These cookies are required for the Services to function. They enable core features such as login sessions, security, and remembering your cookie-consent preferences. Because they are essential, they cannot be switched off through our cookie banner, but you can disable them through your browser settings, which may affect how the Services work.
Performance / Analytics
These cookies help us count visits and traffic sources, see how visitors move around our sites, and understand how our services perform. The information is generally aggregated and does not directly identify you.
Functional
These cookies remember choices you make, such as whether you have already completed a signup gate, and allow us to provide enhanced features and more personalized content.
Marketing
These cookies are used to deliver and measure marketing campaigns, understand account-level interest in Arca, and help us reach relevant audiences. They may be set by us or by our third-party partners.

You can also withdraw or change your choice by clearing your browser cookies for our sites and revisiting the page. When you do, the cookie banner will appear again.
7. Do Not Track
Some browsers transmit “Do Not Track” signals. We do not currently respond to these signals because no common industry standard has been adopted.
