Cookie Policy

1. What Are Cookies

Cookies are small text files stored on your device when you visit a website. We also use similar technologies such as browser local storage for certain preferences. This policy explains what we use and why.

2. How We Use Cookies

We use cookies and similar technologies to keep the platform secure, maintain your sign-in session, remember interface preferences, and—only if you consent—measure product usage through Google Analytics.

We do not sell cookie data. Optional analytics are only activated after you opt in through our consent banner or cookie settings panel.

3. Cookie Categories

Essential cookies (always active)

• auth-token — keeps you signed in to your Polyblock account
• Required for authenticated API requests, trading, wallet access, and account security

These cookies are strictly necessary for the service you request and do not require consent under applicable ePrivacy rules.

Analytics cookies (optional)

If you opt in, we load Google Analytics 4, which may set cookies such as:

• _ga — distinguishes users
• _ga_* — persists session state for GA4
• _gid — distinguishes users for 24 hours

These cookies help us understand traffic, feature usage, and conversion events so we can improve the product. They are not loaded unless you choose "Accept all" or enable Analytics in cookie settings.

4. Local Storage

We use browser local storage (not cookies) for non-essential UI preferences such as chart layout, trade panel presets, hidden positions, and support chat visitor identifiers on docs pages. These items support product functionality and are not used for third-party advertising.

Your cookie consent choice is stored in local storage and in a first-party consent cookie so we can remember your preferences across visits.

5. Managing Your Preferences

You can update your choices at any time:

• Use the cookie banner when you first visit
• Click cookie settings in the site footer
• Clear cookies in your browser settings (this may sign you out)

If you reject analytics cookies, we do not load Google Analytics and we remove known GA cookies from your browser where possible. Essential cookies remain active so the platform can function.

For broader privacy rights and data handling, see our Privacy Policy.

6. Changes to This Policy

We may update this Cookie Policy from time to time. Material changes will be posted here with an updated "Last Updated" date.
