Browser tools process data on your device. Input text is not persisted by default; optional local drafts use the al:<site>:v1:<purpose> namespace and affect this site only. Analytics is off by default and, when enabled, sends only event names and whitelisted metadata — never files, text, URLs, prompts or credentials.
