Privacy Notice

Last updated 8 October 2026

What we collect

  • Your account email. Your password is handled by our sign-in service and is never stored in plain text.
  • Your sign-in token (kept on your own device by the Chrome extension) so you stay signed in.
  • The websites you analyze: the page address and the public text of that business's website, which our server fetches to write the analysis. Also your saved prospects, contact emails you add, and the messages we write for you.
  • For the AI sales agent: your business profile, campaigns, the prospects you approve, drafts, sent messages, prospect replies, opt-outs and appointments.
  • Reviews you send us, so we can improve the extension.
  • Payment details are handled by Stripe. We never see or store your card number.

Gmail and Google Calendar (only if you connect them)

  • Gmail: we send the emails you approve from your own Gmail, and read only the replies in conversations SignalCloser started. We don't read the rest of your inbox.
  • Google Calendar: we check your selected calendar for busy times so we only offer free slots. We create, read back and cancel the meetings your prospects book.
  • Gmail and Calendar content we handle: recipient addresses, subjects and bodies of emails SignalCloser sends for you; the replies in those same conversations; busy/free times and the meetings SignalCloser books.
  • Google access tokens are stored encrypted and used only to run your agent. Google data is not sold, not used for ads and not used to train AI models.

Google API Limited Use

SignalCloser's use and transfer of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. We use Google data only to provide the features you turned on, we don't transfer it except as needed to provide those features, comply with law or as part of a merger with your notice, we don't use it for advertising, and people don't read it unless you ask us to (for support), it's needed for security or law, or it's aggregated and anonymized.

What gets sent automatically

You approve every sales email, follow-up and AI-written reply before it is sent. Booking confirmations are different only if you choose: on the campaign approval screen there is a separate, optional box. If you tick it, when a prospect picks an offered time and the Calendar event is confirmed, one booking-confirmation email goes to that prospect automatically. If you don't tick it, each confirmation waits as a draft for your approval. Campaigns approved before this option existed are treated as not ticked. You also get a briefing email about each booked meeting. Anyone who says no or unsubscribes is stopped immediately. SignalCloser does not make phone calls.

How we use it

Only to run SignalCloser for you, provide support and improve the product. We never sell your data.

Chrome extension

The extension reads the address of the page you're on only when you click Analyze. It doesn't track your browsing. Your sign-in token is kept on your device and is cleared when you sign out.

Keeping and deleting your data

We keep your account data while your account exists so your pipeline and conversations stay available. You can disconnect Gmail or Calendar at any time with the Disconnect button in your dashboard; this deletes the stored Google tokens for that connection and stops all sending, reply checks and booking through it. You can also remove SignalCloser's access in your Google Account under Security, Third-party access. Email support@gerardgrogans.com from your account email to get a copy of your data or have your account and its data deleted; we confirm by email when it's done, normally within 30 days. Uninstalling the extension removes everything it stored on your device.
