Privacy Policy

Overview

51828 is designed to provide calculators and educational content without requiring an account. The calculator fields run in your browser.

Calculator inputs

51828 does not intentionally collect calculator inputs, quote comparison totals, worksheet notes, or checklist selections on its own servers. Calculator estimates are produced in the visitor's browser.

Some worksheet and checklist fields may be saved in your browser's local storage so the page can remember your notes on the same device. You can clear saved worksheet data with the page controls or by clearing site data in your browser.

If you use a shareable calculator URL, the URL may include values such as size, state, scope, scheduling, or quote total. Anyone you share that URL with can see those values, and hosting or browser history systems may record URLs that you visit.

Information you actively submit

51828 receives information only when you actively send it, such as by emailing wwang@51828.com or using the quote submission page to prepare an email. The quote submission form opens an email draft; 51828 does not receive the quote unless you send that email.

For quote examples, send only anonymized summaries. Do not send names, street addresses, phone numbers, email addresses, account numbers, signatures, license plates, QR codes, barcodes, payment information, or raw invoices unless specifically requested for a private review.

Current cookies and third-party vendors

51828 does not currently serve Google AdSense ads, sponsored placements, paid rankings, affiliate product blocks, or active third-party advertising scripts. The current static site does not require account-registration cookies.

External links on source, permit, GitHub, or reference pages may take you to third-party websites. Those websites have their own privacy and cookie practices.

Google AdSense and advertising cookies

51828 may apply for or enable Google AdSense in the future. If AdSense is enabled, third-party vendors, including Google, may use cookies to serve ads based on a user's prior visits to this site or other sites. Google's advertising cookies may allow Google and its partners to serve ads based on visits to 51828 and/or other websites.

Google explains that AdSense cookies can be used for ad relevance, campaign reporting, and limiting repeated ad views. Google also explains that AdSense advertising cookies may be associated with domains such as doubleclick.net or Google domains such as google.com.

If third-party ad serving is enabled, other Google-certified vendors or ad networks may also use cookies or similar technologies to serve or measure ads. 51828 should update this page with active advertising provider details before those tools are enabled.

Managing cookies

You can manage cookies through your browser settings. Most browsers let you delete existing cookies, block third-party cookies, block all cookies, clear local storage and site data, or use a private browsing mode.

You can manage personalized ads from Google through Google Ads Settings. You can also visit AboutAds.info choices for participating third-party advertising opt-out tools.

If 51828 adds a consent banner or consent management platform in the future, use that control to set site-specific advertising or analytics choices where available.

Analytics

51828 does not currently name an active analytics provider. If analytics are added later, this policy should be updated with the provider name, what is measured, whether cookies or local storage are used, and how users can manage those settings.
