Simday (“Simday”, “we”, “our”, or “us”) provides eSIM services through our website and mobile applications (the “Service”). This Privacy Policy explains how we collect, use, share, store, and protect your personal data, and your rights regarding that data.

Sentry monitors website errors and performance and may process the page URL, browser and device details, IP address, and error data. Session replay is disabled.

- The time the reading was taken
