Privacy Policy

We collect no data from the tools themselves. Every calculator, converter, and generator on this site runs entirely inside your browser. The numbers, text, and files you enter are processed locally and are never transmitted to our servers.

We use Google Analytics to count anonymous page views. This helps us understand which tools are useful and where to focus our work.

Our analytics configuration:

• client_storage: ‘none’ — Google Analytics does not set its usual cookies on your device.
• anonymize_ip: true — your IP address is truncated by Google before storage.
• No user identifiers, no cross-site tracking, no advertising.

Use of Google’s service is governed by Google’s Privacy Policy. {{TODO: legal review — confirm GA disclosure wording for target jurisdictions (GDPR, CCPA).}}

We use New Relic Browser to collect anonymous performance metrics, JavaScript errors, and pathname-only page-view counts. This helps us keep the site fast and reliable.

Our New Relic Browser configuration:

• Cookies, persistent browser sessions, session traces, and session replay are disabled.
• Browser console capture and manual browser logs are disabled.
• Page metadata contains only the pathname; query strings are removed before transmission.
• No user identifiers or custom user data are sent.
• New Relic may process provider-derived device, browser, IP address, and network fields needed to deliver telemetry.

Use of New Relic is governed by New Relic’s Terms and Conditions.

We use first-party storage only — never third-party advertising or tracking cookies. The site stores the following on your device:

• Theme cookie — a first-party cookie remembering your selected color theme, so the server can render the correct theme on first paint.
• Theme in localStorage — the same theme preference, mirrored client-side for instant switching.
• Service worker cache — pages and assets you opt to cache for offline use via the offline settings.

None of these contain personal information. You can clear them at any time using your browser’s site-data controls.

The site loads resources from these third parties:

• Google Fonts — typefaces are loaded from fonts.googleapis.com. Google may log your IP as part of standard web-server logging.
• Google Analytics — see the section above.
• New Relic— anonymous frontend observability metrics sent to New Relic’s EU region; see the “Frontend observability” section above.
• Google Forms — embedded on the contact page. Submitting a form sends the data you typed to Google’s servers under their privacy policy.

Because we hold no personal data about you on our own servers, there is nothing on our side to access, correct, export, or delete. To remove locally stored preferences, clear site data for this domain in your browser. To remove data you submitted via a Google Form, contact us through that same form and we will delete the submission. {{TODO: legal review — confirm rights wording for GDPR (Articles 15–22), UK GDPR, and CCPA.}}

This site is not directed at children under 13. We do not knowingly collect information from children.

We may update this policy from time to time. Material changes will be reflected by the “Last updated” date at the top of this page. Continued use of the site after changes are published constitutes acceptance of the updated policy.
