Privacy Policy

Last updated: 25 August 2026

BuildMetricLab is operated by Brightscale Labs Limited (registered in England & Wales). For visitors in Australia we handle personal information in accordance with the Privacy Act 1988 (Cth) and the Australian Privacy Principles (APPs).

What we collect

• Calculator inputs: the numbers you type into calculators are processed locally in your browser. They are not transmitted to our servers or stored on our end.
• Anonymous usage analytics (no cookies): when a calculator is used we record an anonymous event containing the tool, the name of the figure it produced, approximate state/region and device type (from network headers). The values you type and the results calculated from them are not transmitted. It contains no cookies, no IP addresses, and no information that can identify you personally.
• Optional analytics — Microsoft Clarity: if you consent to analytics through the InMobi Choice consent message, we load Microsoft Clarity on the calculator pages and in the Estimator, which records aggregated heatmaps and anonymised session replays to help us improve the tools. Input fields are masked, so the values you type are not captured, and in the Estimator the entire workspace is masked — jobs, clients, prices and all. Clarity runs only with your consent and you can withdraw it using the Cookie preferences link in the footer, or the one on the Estimator's Your details screen. See our Cookie Policy for the cookies it sets.
• Optional analytics — Google Analytics 4: the same consent loads Google Analytics 4, which records page views, referral source, approximate location (country/region, derived from a truncated IP address) and device type so we can see which calculators are used. Calculator inputs are never sent to Google. We do not enable Google Signals, advertising features or remarketing, so your visit is not used to target ads. Analytics runs only with your consent, withdrawable in the same way.
• Estimator: nothing at all. It has no accounts, and every estimate built there stays in your own browser. See "The Estimator" below.
• Voluntary feedback: if you submit feedback through the site, we store the message plus any contact email you choose to provide, to reply to you. You can request deletion at any time.

The Estimator

The Estimator at buildmetriclab.com/estimator is where calculator results become a priced estimate you can print.

There is no account. You build a complete estimate, print it and export it without signing in, because there is nothing to sign in to. Everything you enter — job and section names, the client name and site address, line items and quantities, your prices, and your own business details — is held by your own browser and never reaches us. We store none of it, so there is nothing for us to share, sell, lose or be compelled to hand over. The client names and addresses you type belong to your business, not ours; we never see them.

It does not survive clearing your site data, and we cannot restore it: the file you export is the only copy that lasts.

If you accepted analytics, Microsoft Clarity records how the app was used — with everything in the workspace masked, so the contents of your jobs are not in the recording either.

What we do not do

• We do not set advertising cookies; we set analytics cookies only if you accept them.
• We do not sell personal information to third parties.
• We do not share your calculator inputs with anyone.
• We do not use your data to train AI models.

Who processes your data

• Microsoft (Clarity) — heatmaps and session replay, only after you consent. See Microsoft's Privacy Statement.
• Google (Analytics 4) — audience and page-performance measurement, only after you consent. See Google's Privacy Policy.
• Cloudflare — hosting, content delivery, the worker that records the anonymous, cookieless usage events described above, and the worker that serves the Estimator. That worker keeps no database: it sends the app to your browser, and your estimates stay there.

Some of these providers may store or process data outside Australia (an overseas disclosure under APP 8). We only use reputable providers with their own privacy commitments.

Your rights

Under the Privacy Act and the Australian Privacy Principles you may request access to, correction of, or deletion of any personal information we hold about you, and object to processing. Contact: contact@brightscalelabs.com.

If you are unhappy with how we handle your personal information you may complain to the Office of the Australian Information Commissioner (OAIC) at oaic.gov.au.
