Cookie Policy

1. What a cookie is

A cookie is a small file a site stores on your device. Some are essential for the service to function; others are optional. We describe ours below.

2. Cookies and storage we use

• Session cookie (strictly necessary)— keeps you signed in and secures the session. Set by Customs OS; up to 90 days, rolling.
• Session cache (strictly necessary)— a short-lived performance cache that avoids re-reading your session on every request. Set by Customs OS; 5 minutes.
• customs-os-language (functional)— remembers your language preference, including server-side to prevent a flash of the wrong language. Set by Customs OS; 1 year.
• Cloudflare Turnstile (strictly necessary)— bot and abuse protection on sign-in, sign-up, and password-reset. Set by Cloudflare; session / short-lived.
• Vercel Web Analytics (cookieless)— aggregate, anonymous usage measurement. Does not set identifying cookies.
• Vercel Speed Insights (cookieless)— aggregate performance measurement. Does not set identifying cookies.

We do not set advertising cookies, marketing pixels, or third-party cross-site trackers on product surfaces.

3. Your choices

Because the product uses only strictly necessary and functional cookies, and analytics is cookieless and non-identifying, the service does not require a consent banner to function lawfully. You can still:

• Block or delete cookies in your browser settings (which will sign you out and reset your language preference).
• Contact privacy@customsos.com with any question about this policy.

4. Changes

We will update this page if our cookie use changes, and revise the “last updated” date. See also our Privacy Policy.
