Short version: there is nothing to collect, so nothing is collected.
Nothing. The expense report title generator is a static web page with a small JavaScript file. When you click "Generate titles", the titles are created inside your own browser tab. No request is sent to any server, no account exists to attach data to, and no analytics script watches what you generate.
TallyTitle sets no cookies and uses no local storage, session storage or tracking pixels. Your generated titles exist only in the page's memory; closing or reloading the tab discards them.
This site loads no third-party analytics, advertising or social-media scripts. The only external requests are the font files from Google Fonts, which are subject to Google's own privacy policy.
