By creating an account and using Signal by Expandeum (“Signal”), you agree to these terms. If you don't agree, don't use Signal.
Signal connects to email accounts you authorize (Gmail, Microsoft, IMAP/SMTP, or demo mailboxes) and uses AI to summarize, prioritize, and extract business signals (tasks, invoices, contacts, calendar events) from your email. You control which mailboxes are connected and can disconnect them at any time.
Summaries, priority scores, extracted tasks/invoices/events, and suggested replies are generated by AI and may occasionally be inaccurate or incomplete. You're responsible for reviewing AI-generated content (especially suggested replies and extracted invoice amounts) before relying on or acting on it.
Signal can generate a private calendar subscription link (ICS feed) containing events you've confirmed. Anyone with that link can view those events — keep it private, and regenerate it from Settings if you believe it has been exposed.
Signal is provided “as is” without guaranteed uptime. We aim for reliable service but don't guarantee uninterrupted access, and we're not liable for lost business opportunities arising from downtime.
Our Privacy Policy describes what data we collect and how it's used, including that email content is sent to Anthropic's Claude API for AI analysis.
You may stop using Signal and request account deletion at any time by emailing adam@expandeum.com. We may suspend accounts that violate these terms.
We may update these terms as Signal evolves. Continued use after a change means you accept the updated terms.
