Cookie Policy

Cookies are small text files stored on your device when you visit a website. They remember your actions and preferences (language, sign-in) so you do not have to reconfigure them each visit.

USDX uses only strictly necessary cookies:

• sb-<ref>-auth-token (Supabase): keeps you signed in. May be split into several numbered cookies (.0, .1) when the token is long. Duration: until sign-out.
• NEXT_LOCALE: remembers the language you chose, among those available on the platform. Duration: 1 year.
• usdx_active_merchant: remembers your active merchant if you belong to several. Duration: session.
• usdx_m3, usdx_m3_merchant: enable interface variants in the admin and merchant panels. Duration: session.

When you sign in with Google, Google may set its own cookies under its Privacy Policy.

We do not use advertising, marketing or cross-site tracking cookies.

We use PostHog to understand how the Service is used. It is configured NOT to use cookies: the identifier is stored in your browser local storage.

• What it records: pages visited, performance metrics (Core Web Vitals) and explicit product events, such as account creation or opening an order.
• What it does NOT record: automatic click and keystroke capture is disabled, and session recording is off unless we deliberately enable it to debug a specific issue.
• Profiles: a person profile is created only for identified users; anonymous browsing stays aggregated.

To opt out, enable the "Do Not Track" signal in your browser — we honor it — or clear the site local storage.

You can control or delete cookies from your browser settings. Blocking strictly necessary cookies will prevent sign-in.

We may update this policy to reflect changes in the cookies we use. Updates are published on this page with the date indicated.
