bl4tools.com is a fan-made Borderlands 4 toolkit. We do not sell or share any personal data, and we do not require accounts to use the site.
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.
Email subscriptions
If you subscribe to SHiFT code alerts or patch notifications, your email is stored in our own internal subscriber database (Postgres) on infrastructure we operate. We do not pass your email to a third-party marketing platform. You can unsubscribe in any email we send. We never sell or share your email with third parties.
Build planner data
The build planner saves your current build in your browser. When you click Copy share link, the build is encoded into the URL. We do not transmit your build to any server. Only the people you share that link with can see your 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.
