Your calculator input
Your household selection, currency, annual income and result are used only in the current page in your browser. The calculator does not send this information to an API or database.
We do not write calculator information to:
- the page URL or query string;
- cookies or session storage;
- local storage;
- a user account or cloud history; or
- analytics or advertising services.
Refreshing or leaving the page clears the current calculation.
Analytics and advertising
This version of HK SIBBS does not use third-party analytics, advertising, session replay or device fingerprinting. We do not sell calculator input or use it to build a user profile.
Hosting logs
Our static hosting provider or content delivery network may create basic technical access logs when it serves the website. These can include information such as an IP address, request time, requested page, browser details and security events. Calculator income is not placed in URLs or business requests, so it is not included by the calculator in those logs.
External links
Links to government and other source websites take you away from HK SIBBS. The destination website controls its own cookies, logs and privacy practices. Check its privacy policy before providing personal information.
If you email hi@hksibbs.com, your email provider sends the information you include. Do not send identity, tax or visa documents. We use messages to respond to or investigate the issue you report.
Changes to this policy
We will update this page if the product begins using new storage, analytics or data-processing services. The review date at the top will change when the policy is revised.
