Privacy

Last updated: July 19, 2026

HomeMaterialBase is built so a pad size or paint room does not require an account. Calculator inputs are processed in your browser. We do not sell a dossier of your DIY dimensions.

The short version

• Lengths, widths, depths, waste %, bag sizes, coverage rates, and other calculator inputs
• Results computed in the browser (Worker when available) — not uploaded as a materials takeoff
• Optional theme preference may live in localStorage on your device only

Accounts

There are none. No sign-up, no saved job list on our servers, no mailing-list wall before the calculators work.

Analytics and ads

We use Google Analytics 4 (measurement ID G-X9KYP0HXGV) to understand aggregate traffic — pages viewed, approximate country/region, device type, browser, and referral source. IP addresses are anonymized. Analytics is not linked to calculator inputs or any account (we do not have accounts). Using the tools does not require analytics.

Consent Mode defaults: analytics_storage granted for measurement; ad_storage, ad_user_data, and ad_personalization denied until advertising is active. Config also disables Google signals for this property. GA4 may set cookies such as _ga for session measurement.

Google's privacy policy: policies.google.com/privacy. Opt out with Google's Analytics Opt-out Browser Add-on.

Display ads are not enabled today; reserved layout slots may appear empty. Hosting (Cloudflare) may process standard request metadata — IP, user agent, path, timestamp — for security and abuse prevention. Those logs are not used to reconstruct the numbers you typed into a calculator.

What may leave the device

• Email you send us voluntarily if you contact support
• Aggregate Google Analytics 4 traffic data (not calculator inputs) — see above
• Normal host security logs as described above
