bl4tools.com is a fan-made Borderlands 4 toolkit. No account is required for the tools. Advertising, analytics, shared URLs and voluntary email contact have different data flows, described below.
Analytics
We use Plausible Analytics for aggregate page-view data and Google Analytics 4 for traffic measurement. These tools help us understand which guides players actually use.
Contact and updates
The site currently offers an RSS update feed rather than an email signup form. If you email the contact address, your message and address are part of that correspondence. For a question about an earlier subscription, contact hi@skybringup.com.
Build planner data
The planner saves the V2 allocation in this browser’s local storage. Copy share link encodes the allocation in the URL query. A shared query is visible to anyone receiving the link and can be present in hosting or measurement logs when the URL is requested. Do not include personal information in a shared link. Clear site storage to remove the local build.
Embedded video
Embedded YouTube videos may set cookies when you click play. Refer to Google's privacy policy for details.
Advertising
We display advertising through Adsterra placements. Ad partners may use cookies or similar technologies to measure ad delivery and prevent fraud.
Affiliate links
We may include affiliate links to PC hardware, Steam game pages and accessory stores on the /fix/ pages. These links do not change the price you pay; we may earn a small commission if you purchase. Affiliate links are clearly disclosed where present.
