NuncioPrivacy policy
Last updated: September 1, 2026 · applies to the Nuncio app and the getnuncio.app website
The short version
Nuncio has no servers of its own, no accounts of its own and no advertising. Your mail travels between your Mac and Google — never through us. We could not read your mail even if we wanted to; there is simply nothing on our side to receive it. The one thing you can share, if you choose to, is anonymous usage statistics — off by default, and never about your mail.
What the app collects
Nothing, unless you turn it on. Out of the box Nuncio sends nothing at all: no crash reports, no usage measurement, no identifier of any kind.
Under Settings ▸ General you can switch on anonymous usage statistics. It is off by default and stays off until you say yes; Nuncio asks once, and "Don't share" is a full answer. If you do switch it on, the app sends to TelemetryDeck (Germany): your app and macOS version, your language, your settings (floating panel, notifications, badges, theme, memory mode) and which Google tools you open. The number of accounts is sent as a range, never exactly.
What is never sent: email addresses, account names, subjects, message contents, unread counts, or anything typed or read inside the app. Your identifier is a random number created at installation, hashed on your Mac and hashed again on TelemetryDeck's server — neither we nor they can trace it back to you. TelemetryDeck stores no IP addresses.
Subscription data. Your subscription is an App Store subscription. The app passes each App Store transaction (product, purchase and expiry dates, no name or email) to RevenueCat (United States), a subscription service that only knows you by a random identifier the app creates. That is how we see whether trials, renewals and refunds work as they should. This happens regardless of the statistics setting.
Where your data lives
- Your mail and sign-ins. Each account signs in to Google directly, inside its own isolated storage on your Mac — comparable to separate browser profiles. Cookies, cache and site data never leave your computer and never mix between accounts.
- Your password. You type it on Google's own sign-in page. Nuncio never sees, stores or forwards it.
- App settings. Account names, colors and preferences are stored locally on your Mac and nowhere else.
- Downloads. Files you download are saved to the folder you choose, on your Mac.
What leaves your Mac
Only the traffic you would also generate in a browser: connections from your Mac to Google's services within your own personal sign-in — loading Gmail, sending mail, and periodically checking Google's standard unread feed to show badge counts. That traffic is governed by Google's privacy policy, exactly as when you use gmail.com yourself. No traffic goes to Monto Bleu BV.
Notifications and Focus
Notifications are composed and shown entirely on your Mac through macOS. If you allow Nuncio to read your Mac's Focus state (so the floating panel stays quiet during Focus), that state is read locally and never transmitted.
This website
getnuncio.app uses Clicky (Roxr Software Ltd.) for visitor statistics: which pages are opened, from which country and via which link. It tells us which parts of this site are actually useful. Clicky may set a cookie to recognise a returning visit and processes your IP address; it is never linked to your mail, your Google accounts or anything you do inside the app. The site is also served by Cloudflare, which may process technical data (such as IP addresses in server logs) strictly to deliver the site securely; see the privacy policies of Clicky and Cloudflare. The app itself sends nothing unless you switch on anonymous statistics; Clicky runs on this website only.
Your rights
Under the GDPR you have rights of access, correction and deletion. Because Nuncio processes no personal data on our side, there is nothing we could hand over, correct or delete — everything is on your Mac and in your Google account. For mail data itself, Google is your provider. Deleting the app and its data is described in the FAQ.
Changes
If Nuncio ever changes in a way that affects privacy, we will update this page and state the change plainly at the top. The promise above — nothing about your mail ever leaves your Mac, and statistics stay off unless you say yes — is the product's foundation, not a temporary policy.
