Privacy policy

BuildWiseCalc is an early-stage calculator platform. We respect your privacy and keep data collection to a minimum.

This policy describes what we collect, how we use it, and the choices you have. It is written to be understandable — not to overwhelm you with legal jargon.

When you use our calculators, inputs stay in your browser session unless you choose to share them elsewhere. We do not require an account for the MVP.

We use privacy-friendly analytics (Umami) to understand general usage — such as page views and referrers — without building advertising profiles.

Your browser may store preferences locally (for example, metric vs imperial) using local storage so settings persist between visits.

We do not use advertising cookies. Analytics may use a minimal cookie or similar technology to distinguish visits; Umami is designed to avoid cross-site tracking.

Calculator preferences and UI state may be saved locally on your device for convenience.

Usage data helps us improve calculator accuracy, fix bugs, and understand which tools matter most.

If you submit the contact form in the future when backend support is added, we would use your message only to respond to you.

We do not sell your personal information. We do not share data with advertisers.

We may use infrastructure providers (such as hosting and analytics) who process data on our behalf to operate the site.

We take reasonable steps to protect the site and any data we process, including HTTPS and standard hosting security practices.

No online service can guarantee absolute security; please avoid sending sensitive personal information through the contact form.

You can clear local storage in your browser to reset calculator preferences.

You may use browser extensions or settings to limit analytics scripts if you prefer.

For questions about this policy, use our contact page.

We may update this policy as the product evolves. The “Last updated” date below reflects the latest revision.

Continued use of BuildWiseCalc after changes means you accept the updated policy.
