Data we collect

Nuclear Toolkit sends anonymous usage events to PostHog (posthog.com) to help us understand which features are most useful. Each event includes:

• Which screen or tab you visit, and time spent
• Nuclides you open (element symbol, mass number, and primary decay mode)
• Calculator and tool interactions
• Your IP address (logged automatically by PostHog)
• Device type, operating system, and app version

What we do not collect

• Your name, email address, or any account details
• Values you type into calculators or converters
• Precise location (PostHog may infer an approximate country from your IP)

Purpose

Usage data is used only to prioritise features and fix usability issues. It is not sold, shared with advertisers, or used for any other purpose.

Data processor

PostHog, Inc. processes event data on servers in the United States. See posthog.com/privacy for PostHog's own privacy policy.

Opt-out
