We keep it simple: we don’t ask for personal data.
We do not collect, store, or sell personal information. The calculators run in your browser.
Some calculators save your last inputs in your browser’s localStorage for convenience (so values persist on reload). This data stays on your device and is not sent to our servers. You can clear it via your browser settings.
We don’t set our own tracking cookies. We load third-party libraries from CDNs (e.g., Bootstrap, html2canvas, jsPDF). Those services may have their own privacy policies. If we add analytics or advertising in the future, we will update this page and offer appropriate consent controls.
When you export a PDF/PNG, the file is generated locally in your browser and saved to your device. We do not receive a copy.
This policy may change as we add features. We’ll post updates here.
