SynoMail is a native macOS client for Synology MailPlus Server. It connects only to the Synology NAS you enter and to the services that NAS provides. SynoMail has no servers of its own, no account, and no analytics. The developer, IBCSC ASBL, does not collect, receive or have access to any of your data.
What we collect
Nothing. SynoMail sends no data to the developer or to any third party. It communicates only with your own NAS at the address you provide.
Your credentials
Your DSM password and the two-factor device token are stored only in the macOS Keychain on your Mac. They are used solely to sign in to your NAS and never leave your computer except as part of the sign-in request to that NAS.
Mail, calendar and contacts
Your messages, events and contacts stay on your NAS. SynoMail reads and writes them through the Synology WebAPI over the connection you configure. Nothing is copied to the developer.
AI features
The optional AI assistant (summaries, drafting, translation) runs through AI Console on your own NAS, using the AI provider your administrator configured there. The request goes from the app to your NAS. IBCSC is not involved and receives nothing.
Diagnostics
A local log file may be written on your Mac to help you troubleshoot. It stays on your computer and is never sent anywhere.
Children
SynoMail is a tool for accessing your own mail server and is not directed at children.
