What is stored in your browser
Three families of localStorage keys, and nothing else:
- ndtrlu:settings — chosen theme and the “remember inputs” preference.
- ndtrlu:form:<page> — the last values entered in each calculator.
- ndtrlu:sources — your personal source inventory, if you use that page.
- ndtrlu:dose-log — your dose log (operations and estimated doses).
- ndtrlu:dose-threshold — the reference threshold entered in that log.
Nothing is sent to a server
Calculations run in your browser. No entered value is transmitted to the publisher or to a third party.
Analytics
The site uses Cloudflare Web Analytics, which sets no cookie and builds no individual profile. Aggregated data only shows which pages are used.
Advertising
At launch the site shows no advertising and loads no ad script. If advertising is enabled later it will go through Google AdSense, with Google consent management for the European Economic Area.
Your rights
The publisher holds no data about you, so there is nothing to inspect or delete on their side. For data stored in your browser, you keep full control.
