Privacy

• No accounts, no sign-in, no newsletter.
• Nothing you type leaves your device. The tools compute in your browser. What you enter is kept in your browser’s own storage so a page remembers your inputs; every tool has a “Reset and clear” control that removes it.
• Share links carry only the card and the amounts you entered, nothing else; anyone with the link sees the same scenario.
• No cookies of our own and no advertising trackers. Fonts are served from this site, not from a third party. If the site adds a privacy-respecting visit counter, it will receive page views only, never entered amounts, and this page will say so.
• Links to YouTube and to issuers’ pages take you to those sites, where their own privacy policies apply.
