Privacy
Summary, 11 November 2026. The full privacy policy for QuietGuard and QuietGuard Business is on quietguard.io.
Your trusted list and Activity stay on your phone. We never upload your contacts and we don't sell data. With Eisa, the calls she answers are handled on our server, and the recording is deleted once the message is written.
Who we are
QuietGuard Business is made by Controlled Systems Group Ltd (company number 17118598), 58 Broton Drive, Halstead, CO9 1HB, United Kingdom, the makers of QuietGuard. Contact: support@quietguard.io.
What stays on your phone
The app reads your contacts and incoming calls on the phone itself, to decide which calls ring. Your contacts are never uploaded. Your trusted list, profiles and Activity stay on your phone. There's no spam database and no guessing from strangers' reports.
Eisa
Eisa only answers calls you forward to her number. When she does:
- she tells callers she's an AI and that their message is turned into text and the recording then deleted;
- the message is turned into text and a short summary on our server and sent to your phone; our server keeps no audio, text or summary;
- our server keeps what Eisa needs to work: which of her numbers is yours, your plan's end date, your app language, the business name, opening hours, closed days and "About us" line for the greeting, and a call log (time and caller's number) for the monthly limit, deleted after 90 days.
Help alert
If you set up the help alert, our server keeps your name, your mobile number and the names and numbers of up to two people you choose, so it can text and call them when you ask for help or miss a check-in. No location is used or shared. Removing your help contacts in the app deletes them from our server.
Who helps us
For Eisa and the help alert: Twilio (calls and texts), ElevenLabs (speech to text and Eisa's voice), Anthropic (the summary), Cloudflare (our server) and Google (notifications and Google Play). The full policy lists exactly what each one handles.
Your plan
Google Play handles the payment. We see whether a plan is active, never your card. QuietGuard Business has no ads.
Your rights
"Delete my Eisa data" in the app removes your Eisa record and releases her number. You can ask us what we hold, or to delete it, at support@quietguard.io. You can complain to the ICO (ico.org.uk).
