Privacy & your local data.
What runs on your device, and what happens when you open a video.
Plans stay in this browser
The deployment planner and class notebook use localStorage on this device. We do not send those entries to an application server. Each tool has its own storage key and reset control. Export downloads the current entries as a JSON file. Browsers may clear storage in private mode or when you clear site data.
Session calculator
The calculator processes your entries in the page. It does not store them or retrieve your game account.
Videos and external sites
Video players load from youtube-nocookie.com only after you select a video. YouTube may then receive network and device information and apply its own policies. A direct YouTube link is available if the embedded player cannot load.
Website requests
This first edition includes no advertising or analytics scripts and no account system. Your hosting provider may process ordinary access logs when serving the site. External source links open the destination’s own website; its privacy policy applies there.
Delete or keep a copy
Use Export JSON before resetting a tool. Reset affects that tool on this browser only, and cannot delete copies you have already downloaded.
