RonoxMail desktop app

RonoxMail is a desktop email client published by Appronox Ltd for macOS and Windows. This section explains how the app handles your data, including data it receives from Google and Microsoft when you connect those accounts. You do not need an Appronox account to use RonoxMail; only the optional AI writing feature described below requires one.

Data the app accesses. When you add an account, RonoxMail connects directly from your device to your mail provider so you can read, organise, search, and send your mail. For Gmail accounts, with your consent, it uses Google's OAuth 2.0 sign-in and requests full mailbox access (https://mail.google.com/), which is what the IMAP and SMTP protocols it uses to read, organise, and send mail require, plus your email address and basic profile information (openid, email, profile) to identify the account you signed in to. For Microsoft accounts, it requests permission to read and manage your mail and send mail on your behalf, your basic profile, and continued access (Mail.ReadWrite, Mail.Send, User.Read, offline_access). For other accounts, it uses the server settings and password you enter.

Where your data is stored. Your messages, attachments, signatures, and account settings are stored on your own device. Passwords and access tokens are kept only in your operating system's secure store (Keychain on macOS, protected storage on Windows). Your mail, your credentials, and your Google or Microsoft data are not sent to us, and we cannot access them. The app contains no advertising or analytics; the only information it sends us about itself is the optional crash reports described below. Connections to mail servers use TLS by default.

Sharing. We do not sell or transfer your Google or Microsoft user data, use it for advertising, or use it to develop or train artificial intelligence or machine-learning models, and no person at Appronox Ltd reads it. Apart from the account setup lookups and the optional AI writing feature described below, your data goes only to the mail provider you connected, as needed for the features you use, and to the recipients of mail you send. Images and other remote content in a message are blocked by default; if you choose to show them, your device fetches them directly from the servers that host them.

Optional AI writing feature. RonoxMail will offer an optional feature that drafts email content with AI. It requires an Appronox account and a paid subscription, and we handle your account and billing data as described in the rest of this policy. The rest of the app needs neither. When you use the feature, the app sends only what you type for it, meaning your prompt and your draft, to our servers, which pass it to our AI provider, Anthropic, to generate the text. Your mailbox content is never sent: no received messages, threads, attachments, contacts, or other data from Google or Microsoft. We do not store your prompts or the generated text; we keep only usage counts, which we need to apply your subscription. Because what you type is sent, leave out anything you do not want shared with these services.

Crash reports. To help us find and fix problems, RonoxMail sends a report to Sentry, the error-monitoring service we use (Functional Software, Inc., which stores our data in its EU region), when the app crashes or runs into an error. A report contains only technical details of the error: its type, where in the app's code it happened, the app version, and your operating system and its version. It never contains your mail, subjects, email addresses, contacts, search terms, folder or server names, passwords, or tokens. Email addresses and web addresses are removed from the error details before a report leaves your device, and no account, user identifier, or device name is attached. We use the reports only to fix bugs, on the basis of our legitimate interest in keeping the app working, and keep them for no longer than 90 days. Crash reporting is on by default. You can turn it off at any time in Settings → Diagnostics (“Send crash reports to Appronox”); sending stops at once, and any reports still waiting to be sent are deleted.

Google API Services. RonoxMail's use and transfer to any other app of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

Account setup. To find your mail server settings, the app looks up your email address's domain using DNS (MX records). If that does not identify your provider, the app asks that domain's own autoconfiguration server, sending your full email address, and if necessary Mozilla Thunderbird's public settings database (autoconfig.thunderbird.net), sending only the domain.

Your choices and deletion. You can remove an account in Settings at any time, which deletes its local data and stored credentials from your device. Uninstalling the app may leave local data behind, so remove your accounts first if you want that data gone. You can revoke RonoxMail's access at any time from your Google Account or your Microsoft account. Questions: info@appronox.com.
