Cookie Policy
Last updated July 2026
This policy explains how OS uses cookies and similar technologies — such as browser local storage — on our website and app, and how you can control them. We take an opt-in approach: non-essential cookies are used only if you choose to allow them. The Service is intended for adults aged 18 and over.
What these technologies are
Cookies are small files stored on your device. Similar technologies, such as local storage, work the same way and let the app remember things between visits.
Essential cookies and storage
These are required for the Service to work — to keep you signed in and your session secure, remember your language and theme, store your cookie choice, and cache your profile so the app loads quickly. Because they are necessary for the Service you asked for, they are always on and are not used to track you.
Optional cookies
Optional cookies help us understand how the app is used so we can improve it. They are off by default and used only if you accept them in the cookie banner. You can change your choice at any time.
Partners
Some essential infrastructure we rely on, such as authentication and hosting, may set cookies or storage strictly to deliver the Service. When you use a regulated feature such as buying crypto, our payment partner (for example Stripe) may set its own cookies inside its embedded checkout for the purchase, fraud prevention and identity checks, under its own cookie policy. We do not use cookies to sell your data or to share it for third-party advertising.
Managing your choices
You can accept or decline optional cookies in the banner on our website, and clear cookies and local storage through your browser settings at any time. Declining optional cookies will not stop the core non-custodial wallet from working.
Changes and contact
We may update this policy from time to time. Questions about cookies? Contact support@useos.xyz.
