Privacy

Your calculator numbers stay in your browser.

Calculator entries and results are processed locally in memory. They are not sent to Google, saved in URLs or attached to telemetry. CSV exports are generated on your device. There are no user accounts.

Optional Google Analytics

If you select Allow analytics, Google Analytics 4 receives pageviews and basic usage events: successful calculator submissions and CSV downloads, identified by calculator type. It also processes browser/device information and identifiers associated with analytics cookies. Google processes network information, including your IP address, to deliver its service. We do not send calculator values, results, form contents, user IDs, full referrers or URL query strings.

Google Analytics does not load or send measurement requests before you opt in. Rejecting analytics leaves all calculators available. We also block it when your browser sends Do Not Track or Global Privacy Control. Advertising consent remains denied, Google signals and ad personalization are disabled, and automatic enhanced measurement is off.

We remember your analytics choice in local storage for up to 180 days. With consent, Google Analytics uses first-party cookies beginning with _ga, configured with a 180-day expiry. Use Analytics preferences in the footer to change your choice. Rejecting after acceptance removes these cookies and reloads the page to stop loaded tags. Previously collected data is not removed by withdrawing consent. Google controls its own processing and may process data outside your country. See Google’s Privacy Policy and Google Analytics data practices.

Analytics totals cover visitors who consent and whose browsers allow collection. They will differ from Cloudflare request counts. The hosting provider, Cloudflare, may separately process request metadata such as IP addresses and access logs. Search Console reports aggregate Google Search performance.

Error reporting

Remote error reporting is currently disabled. The optional adapter requires a separate session opt-in and sends only an allowlisted category and page path to a same-origin endpoint. It excludes messages, stacks, query strings and calculator inputs. Provider and retention details will be disclosed before activation.
