1. Overview
ProReckoner ("we", "our", "the site") is committed to protecting your privacy. This policy explains what information we collect, how we use it, and your rights in relation to it.
ProReckoner is a free tool that does not require registration or the submission of any personal information to use any calculator on this site.
2. Information we collect
We do not collect or store any calculator inputs. All calculations happen entirely in your browser — no data you enter into any calculator is sent to our servers.
We use the following third-party analytics and tag management services:
- Google Analytics 4 (GA4) — Collects anonymised usage data including pages visited, time on site, device type, browser, and approximate geographic location (country/city level). IP addresses are anonymised. We use this to understand how the site is used and improve it.
- Google Tag Manager (GTM) — Used to manage and deploy analytics scripts. GTM itself does not collect personal data.
We do not run advertising, sell user data, or share analytics data with third parties beyond what is described above.
3. Cookies
ProReckoner uses the following cookies and local storage:
- Google Analytics cookies — Used to track anonymous usage metrics. These are first-party cookies set by GA4 (e.g.
_ga,_ga_*). They persist for up to 2 years. - pr-units (localStorage) — Stores your Metric / Imperial preference so it persists across visits. Contains only the value "metric" or "imperial".
- pr-region (localStorage) — Stores your AU / US preference on the Finance, Real Estate and Construction pages. Contains only "au" or "us".
No other cookies or persistent identifiers are used. You can clear these at any time by clearing your browser's cookies and site data.
4. Third-party services
This site uses the following third-party services:
- Google Fonts — Loads the Outfit and DM Mono typefaces from Google's CDN. Google may log the request. See Google's Privacy Policy.
- Google Analytics & Tag Manager — Described in Section 2 above.
- Netlify — This site is hosted on Netlify. Netlify may log server access requests (IP address, page requested, timestamp) as part of standard web hosting. See Netlify's Privacy Policy.
5. Children's privacy
ProReckoner is not directed at children under 13 years of age. We do not knowingly collect personal information from children.
6. Your rights
Because we do not collect personal information beyond anonymised analytics, there is no personal data for us to provide, correct or delete. If you wish to opt out of Google Analytics tracking, you can use the Google Analytics Opt-out Browser Add-on.
7. Changes to this policy
We may update this policy from time to time. The "Last updated" date at the top of this page will reflect any changes. Continued use of the site after changes constitutes acceptance of the updated policy.
