Local saves
When you save a build, its class, level, allocation, snapshot, optional name and save time are stored in this browser’s localStorage. Per-class drafts are also saved locally as you edit; they can be cleared from the calculator. Backup exports contain your saved names and links. They stay on this device. Remove individual saves in the planner, or clear site data in your browser.
Sharing
A shared build is encoded in the URL fragment. Anyone you give the link to can read the build. The fragment is not sent in a normal HTTP request to the website server. Do not put personal information in links.
Hosting and analytics
Cloudflare hosts this site and provides traffic measurement. It may process ordinary request, browser and device data needed to deliver, measure and protect the service.
Adsterra advertising
Pages display a labeled 300 × 250 banner supplied by Adsterra and its advertising partners. Advertising is not an endorsement of the offers shown.
The provider and its partners may process IP address, browser and device information, page and ad interactions, and may use cookies or similar technologies to deliver and measure advertising and prevent fraud. Our calculator does not intentionally transmit saved build names or allocations to the advertising provider. See Adsterra’s privacy policy. You can manage cookies through your browser settings.
Former notification subscriptions
Monetag advertising has been removed. We retire its previous notification worker when you revisit. If you previously allowed notifications, you can also revoke this website’s notification permission through your browser site settings. Removing a subscription does not delete information previously received by the former provider.
External sources
Source and license links take you to other sites with their own privacy practices. Calculator scripts and interface images are served locally. Advertising loads from the provider and its partners. Following a source link opens that external website.
