Short version: the calculator runs locally, your inputs stay on your device, and ads run in consent mode without consent.
Last updated: February 2, 2026.
If you choose to save your inputs, the calculator stores them locally in your browser so you can return later. The data does not leave your device.
At this time, we do not set first-party cookies for the calculator or user accounts.
We show Google AdSense ads in consent mode. Consent is not given by default, which limits the use of cookies and personal data for ad personalization and measurement.
If consent is granted in the future, Google may use cookies or similar technologies for personalized ads or measurement, subject to your choices and applicable law.
We may use basic, aggregated analytics to understand usage and improve the site. We do not intentionally collect sensitive personal information.
If you are in the EU/EEA/UK, you can request access, correction, deletion, objection, and data portability where applicable.
