What stays in your browser
Your settings, saved builds, Creator and Optimizer workspaces, the theme and whether you have seen the welcome window are kept in your browser's local storage. They never leave your device unless you share a build link yourself. Clearing the site's data in your browser removes them.
Anonymous usage counts
To see which features are used, the site sends anonymous events to its own small server (a Cloudflare Worker): for example "a build was generated" with the class, archetype, level range and main skill, and a ping every two minutes while the page is open (to count active visitors).
- No accounts, no names, no email addresses.
- Your IP address is not stored. The server keeps a code made from a random value that changes every day, your IP address and your browser name; the random values are deleted after two days, so the code can't be linked to you or across days.
- Counts are kept per day. Active-visitor entries are deleted after two days.
Builds and ability trees you publish
When you press Publish (Build Library), the build code, the name, the optional author name and description you type are sent to the site's server for review. After approval they are public on the site. Ability trees sent earlier with "Add a guide tree" are kept on the same terms; the site no longer accepts new ones. The day's visitor code is stored with it to limit how many you can send per day; once that day's random value is deleted it can't be linked to you.
Advertising (Google AdSense)
The site may show up to two ads from Google AdSense: one at the bottom of the page and one at the end of the build column on wide screens. No pop-ups, full-screen or sticky ads.
