At Jstoker, we value your privacy. This Privacy Policy explains how we handle data and local storage when you use our website and services.
We do not collect, store, or transmit your personal data to our servers. Any data generated while using our site remains entirely on your own device.
We use cookies and local storage (localStorage) strictly on your device to ensure basic site functionality and enhance your user experience. This local data is never sent to Jstoker or any third parties.
Specifically, local storage and cookies are used for:
• Banner Preferences: Storing your choice to dismiss banners or notifications so they do not reappear during your session.
• Calculator API & Features: Temporarily holding input and output values required for calculator functionality on your device.
• History & Saved Data: Saving your usage history or preferences locally within your browser so you can access them on return visits.
Because all data is stored locally in your browser, you have full control over it. You can clear your browser's cookies and local storage at any time through your browser settings. Clearing this data will reset your saved preferences and history.
If you have any questions about this Privacy Policy, feel free to reach out to us at Jstoker.
