Calculator inputs
NetPayKit calculators are designed to perform calculations in your browser. We do not require an account, and calculator inputs are not intentionally submitted to or stored by NetPayKit. Do not enter names, Social Security numbers, bank details, or other sensitive personal information into calculator fields.
Technical information
Our hosting and security providers may process routine request data, such as IP address, browser type, device information, requested page, referral information, and timestamps, to deliver and protect the service.
Web analytics
NetPayKit uses Cloudflare Web Analytics to understand aggregate traffic and performance, including page views, referral sources, approximate country, browser and device categories, and Web Vitals. Cloudflare Web Analytics does not use cookies, local storage, or fingerprinting to collect analytics data. Cloudflare states that it removes query strings and visitor IP addresses before storing analytics data. Calculator values remain in your browser and are not sent through the analytics beacon.
Calculator usage events
NetPayKit records a small set of first-party usage events to measure whether a calculator was started, completed, produced a copied or printed output, or displayed a validation error. Each event contains only the event name and the calculator's canonical page path. It does not contain calculator inputs or results, monetary values, query strings, full referrers, cookies, user agents, IP addresses, device fingerprints, or persistent identifiers. Privacy-minimized raw usage and request logs are retained for no more than 14 days.
Cookies and local storage
The public calculators do not require advertising, analytics, or account cookies. Cloudflare Web Analytics works without cookies or local storage. Essential hosting, security, or preference technology may be used when necessary. If our practices materially change, this policy and its update date will be revised.
External links and retention
Links to government and other external sites are governed by those sites' policies. Routine server and security records may be retained for a limited period appropriate to reliability, abuse prevention, and legal obligations.
Your choices
You can use the calculator without creating an account. Browser controls can restrict cookies or clear locally stored preferences. Because calculator inputs are not associated with an account, we generally cannot retrieve a calculation by user identity.
