Calculator and filters

Entries are processed in browser memory. The application does not transmit them, put them in URLs, save them to cookies or local storage, or associate them with an account. Refreshing clears them.

Site delivery

Hosting necessarily receives network information such as IP address, request URL and browser information to serve and secure pages. Cloudflare is the selected hosting and security provider. It describes its processing in its privacy policy. Cloudflare may process this information across its global network. Retention depends on the service and purpose; the 90-day email deletion policy below does not apply to Cloudflare’s records. We do not promise that hosting is anonymous or that no personal data is processed.

Cookies and analytics

This code contains no analytics, advertising pixels, embedded third-party content, forms, account system, third-party fonts or application cookies. Cloudflare security features may use necessary cookies, depending on the protection applied to a request; see its cookie documentation. These are distinct from application cookies. We will update this policy before adding optional analytics or advertising technology.

External links

Issuer links take you to independent websites with their own privacy practices. We use a no-referrer policy. There are currently no affiliate tracking parameters. Do not enter sensitive data here.

Contact and rights

Editorial corrections and privacy enquiries: hexagondesigns24@gmail.com.

If you email us, Gmail processes your email address and message. We use enquiries only to respond to questions, handle corrections and address privacy requests. We manually delete resolved enquiry conversations from our mailbox within 90 days of resolution, unless they are needed for an ongoing dispute or legal obligation. Email-provider backup and deletion processes are governed by the provider. Please do not send PAN, Aadhaar, card numbers, OTPs, statements or application documents.

Changes

We will update this page if site behavior changes. No consent banner is included because the application sets no nonessential cookies. Reassess consent obligations before adding analytics, advertising, forms or affiliate technology.
