What is measured
Anonymous page views, referring domains and approved campaign parameters; privacy-safe clicks on links and buttons using interface keys rather than visible text; section and scroll reach; walkthrough video opens, playback milestones and accumulated watch time; and safe aggregate actions inside the linked Vocabulary Studio, Character Builder and Parent Simulation prototypes.
What is not collected
No analytics event intentionally includes names, email addresses, passwords, lesson text, prompts, filenames, translations, generated images, chat messages, parent scenarios or other free-text content. PostHog session replay is disabled, no person is identified, and no portfolio-to-prototype visitor identifier is added to links.
Cookieless attribution
Generic UTM parameters can show that a prototype visit came from this CoTeach dossier, but cookieless analytics cannot reliably prove that an anonymous visitor on this portfolio is the same visitor on a separately hosted prototype.
External AI processing
Some prototypes send user-provided content to external AI providers in order to generate results. Their interfaces explain the relevant processing. Analytics remains separate from that content and receives only safe action labels and counts.
