Cookie Policy

What cookies and similar technologies do

Cookies, browser storage, and similar technologies help Mavunta keep you signed in, protect your account, remember your preferences, and, with your permission, measure and improve the product.

Everything we use is listed below by category, straight from our internal cookie registry, so this page always matches what the product actually sets. Strictly necessary technologies are always on; the rest load only after you agree.

Remember your preferences such as theme, language, currency, and layout so the product feels consistent.

Third-party providers

Some providers that help run Mavunta may set their own cookies while you use the site: Cloudflare, Google. Analytics and marketing providers load only after you consent.

Payment, identity-verification, and support providers may also set cookies on their own domains when you use their flows, such as a checkout or an identity check. Their use is governed by their own terms and our agreements with them.

Managing cookies

Use Cookie Preferences to turn optional categories on or off at any time. Strictly necessary cookies stay on because core services depend on them, and rejecting optional cookies is as easy as accepting them.

You can also clear or block cookies in your browser settings. Blocking strictly necessary cookies may prevent signing in, trading, withdrawing, verifying your identity, or contacting support.

Retention and updates

Each cookie lists its own lifetime above, from a few minutes for a checkout step to about a year for trusted-device and preference cookies. Session values clear when you close your browser.

We may update this policy as cookies, providers, regulations, or product features change. The inventory above always reflects what we currently use.
