Frequently asked questions
Do my prompts leave my device?
No. Classification runs locally in the browser extension. Halo does not upload your prompt to score it, and there is no shadow transcript.
Will it warn every time I mention an invoice?
No. Business and financial words only count as financial data when paired with value-like content, such as an account or routing number. Mentions alone stay quiet.
What happens when a warning appears?
You choose: redact the detected artifact and send, send anyway, or cancel. Halo never rewrites your prompt without you selecting it.
Which assistants are supported?
ChatGPT, Claude, Gemini, and Perplexity today. Additional assistants are added based on early-access demand.
