Privacy policy
What this site stores, how analytics and advertising work, and how to control each choice.
Effective date: September 27, 2026
Data stored on your device
The build planner, private database rows and privacy choices use browser local storage. That data stays on the device unless you copy a build URL, export a CSV or clear browser storage.
Analytics
Google Analytics 4 (measurement ID G-D0M13SM2DB) is enabled by default to measure page visits, device/browser information and interactions such as calculator use and clicks. Google Analytics may use cookies and process usage data. Custom database records and saved build contents are not included in our custom analytics events. The initial page report excludes query strings that may contain shared build values. You can turn off Usage analytics in Privacy choices and save your choice. This preference is stored locally as bklab-consent-v1 and checked before Analytics loads on future visits. Turning analytics off blocks subsequent events and removes accessible Analytics cookies on a best-effort basis. Clearing browser storage resets the choice to enabled. If browser storage is unavailable, a choice applies only to the current page. Advertising has a separate control. See Google’s privacy policy.
Advertising and your choice
Eligible content pages can load one labeled Adsterra native advertisement through profitableratecpmnetwork.com. The homepage can also load a 300 × 250 banner and a 160 × 300 banner through bauval.org. The provider and its partners may process IP address, device and browser information, page URL, referral data, ad interactions, cookies or similar identifiers under the Adsterra Privacy Policy. Ad content and destination pages are supplied by the advertising provider, not the game developers.
Advertising is enabled by default and loads immediately. Privacy, Terms, About and 404 pages do not load the advertisement. Privacy choices stores analytics and advertising together but applies each switch independently. Turning advertising off removes all placements and prevents the ad scripts on later visits. It cannot undo information already processed by a loaded third-party script. Clearing browser storage resets advertising to enabled.
Build URLs and exports
A shared build URL contains the custom part names and values you entered. CSV export creates a file locally. Review either artifact before sharing it with anyone.
External links
Links to Roblox, RoVitals, Google, Adsterra and advertising destinations follow those services’ privacy practices. This site does not control them. Do not enter Roblox credentials on an advertisement destination.
