Save only what you need.

On your device

Project names, sections, measurements, and assumptions are saved in your browser’s local storage. Calculations run in your browser. We do not require an account, name, email, street address, or phone number to use the estimator.

When you share

Choosing to create a share link uploads a project snapshot and PDF to Cloudflare D1 and R2. Anyone with that link can access the estimate. Leave personal information out of project and section names. Links stop working after 30 days; scheduled cleanup removes expired records and files.

A deletion token stays on the originating device. Use the project page to delete a shared copy early. Clearing browser storage removes your local project and deletion tokens, but hosted copies remain until expiry unless deleted first. People who downloaded a PDF may retain their own copy.

Hosting and abuse prevention

Cloudflare serves the site. Its Turnstile service verifies sharing requests, and the Worker uses request IP information for rate limiting. Our application does not store IP addresses in estimate records. Operational logs record error types and cleanup counts, not project content or deletion tokens. Cloudflare may process request metadata under its own policies.

Traffic and performance analytics

We use Cloudflare Web Analytics on public pages to measure traffic and loading performance. The beacon reports page paths, eligible referrers, browser performance measurements, and device/browser information to Cloudflare. It does not use analytics cookies or collect form values. Custom event tracking, session recordings, and advertising tracking are disabled. Project and shared-estimate pages do not load the beacon.

We skip analytics on initial visits with query strings or fragments, potentially sensitive referrers, and browsers requesting Do Not Track or Global Privacy Control. Cloudflare strips query strings and fragments from reported page URLs. Project names, measurements, and share tokens are not sent in analytics payloads.

Partners

Contractor lead collection and display advertising stay off. The concrete calculator can show disclosed QUIKRETE bag links so you can compare bagged mix with your estimate. Some of those links may be affiliate links. If you follow one and make a purchase, CubicTally may earn a commission. We do not receive your payment details or a copy of the order. Manufacturer and retailer sites have their own privacy practices.

External supplier, specification and dealer-locator links leave CubicTally. Those sites collect information under their own policies.
