Calculator inputs

Calculator values are processed in your browser. We do not send the financial, tax or health values you type to our page-view service and do not save them to an account. Initial HTML includes illustrative defaults so the page is readable without JavaScript. Avoid entering personally identifying information into calculation fields.

Anonymous daily browser visits

The header counts the same browser once per day in the America/New_York time zone. Refreshing, opening another tab or changing calculators does not add a visit. This is not a count of unique people: different browsers, private browsing or clearing storage can count separately. A random daily ID and its counting status are kept in first-party localStorage and replaced for the next counting day. The server stores the daily ID and calendar date to reject duplicates; event IDs become eligible for deletion after two days and are cleaned up when new visits arrive. Aggregate daily counts are retained.

If browser storage is blocked, the counter is read-only rather than counting every reload. No calculator inputs, names, email addresses or IP addresses are stored by our counter. Short-lived in-memory network rate limits help reduce abuse. Hosting providers may separately process technical access logs, including IP addresses, for security and operation. Counts recorded before the deduplication change are retained and may include repeat page views.

Email, hosting analytics and fonts

If you email us, we receive your address and the message you choose to send, and may use them to investigate and reply. Do not send sensitive records. Messages may be retained as needed to handle the inquiry, meet legal obligations or prevent abuse. The website uses hosting services and Google Fonts; requests to those services disclose normal network information such as IP address and browser headers to their providers.

The hosting platform may also inject its own client-side analytics into published pages to measure visits and technical usage information. This is separate from our anonymous daily counter and is controlled through the hosting platform’s publishing settings. Calculator input values are not included in our counter requests. Read Replit’s analytics documentation for information about the hosting service.

Google AdSense and advertising cookies

Google AdSense advertising is not currently enabled in this implementation. If enabled in the future, Google and other third-party vendors may use cookies or similar identifiers to serve ads based on prior visits to this or other websites. Google advertising cookies can allow Google and its partners to show personalized ads. Advertising identifiers and related data would then be handled under the providers’ policies and applicable consent choices.

You can manage personalized advertising through Google Ads Settings and learn how Google uses information at Google’s partner-sites policy. Browser cookie settings and industry opt-out choices provide additional controls.

Before advertising is activated, required disclosures and consent controls must be implemented. Where Google’s requirements apply to users in the EEA, UK or Switzerland, a Google-certified consent management platform must be used. This notice is not a replacement for consent or an assertion that this site has been approved by Google.

Your choices and requests

The counter does not require a tracking cookie or local-storage visitor identifier. You can disable JavaScript, although interactive calculators and the live counter will then be unavailable. Contact hoons9096@gmail.com to ask about information supplied through email or to request access or deletion where applicable. Requests may require verification, and legal retention duties may limit deletion. We do not sell the calculator inputs you enter.

Children and changes

The service is for general audiences and is not directed to children under 13. Please contact us if a child has sent personal information. Material changes to our data practices or advertising setup will be reflected on this page with an updated effective date.
