Allodia Mail & Calendar is a sovereign, secure email and calendar app for people and organisations who want to stay in control of their own data.

Unlike the big cloud suites, Allodia Mail & Calendar doesn't ask you to move your mailbox onto someone else's servers. It's a client you own, connecting over open standards (JMAP, IMAP, SMTP and CalDAV) to the mail and calendar infrastructure you already run or trust: your own server, or any provider, anywhere. Your mail stays where you put it. We don't host it, and none of your mail routes through Allodia.

Built in the EU, with privacy by design:
• Your messages sync straight between your device and your provider: nothing passes through us.
• Credentials are stored securely on your device.
• Incoming HTML is sanitised before it's shown, and remote tracking images are blocked by default.
• Product analytics is opt-in and off by default, and can't carry your mail, your addresses or your search terms.
• A rotating, size-capped diagnostic log that never records your mail, addresses or passwords: safe to attach to a support request.

Everything you expect from a modern mail and calendar app:
• Multiple accounts in one unified inbox, with a per-account folder sidebar and quick switching.
• Conversations grouped into threads: the whole thread, including your own replies in other folders.
• Message bodies download after every sync (every size on a computer, up to a size you set on a phone), so opens are instant and the mail you have synced reads offline.
• A rich HTML composer: new messages, replies, reply-all and forwards, with attachments and a From-account picker.
• Write a signature once (formatting, links and your logo) and reuse it on any account, with a separate one for replies. Embedded images arrive visible, even in Outlook.
• All your contacts in one list from every connected account, with address suggestions as you type a recipient. (Read-only for now.)
• An optional Allodia account carries your list of mail accounts to your next device: never your mail, never a password.
• Read/unread, flag, archive, delete, trash and mark-as-spam, plus reply, forward and archive-conversation from the message.
• Configurable swipe actions, with an undo toast.
• A full calendar: agenda, day / 3-day / work-week / week and month grids, with pinch-to-zoom, week numbers, a now line and jump-to-today.
• Per-calendar visibility and colours; read-only calendars are respected: never an edit that can't be saved.
• Meeting invitations arrive as a card above the message: who's asking, when and where, how everyone answered, and your calendar at that time. Accept, Maybe or Decline without leaving the email.
• Fast search across all your accounts, including from: and to: filters.
• Per-account sync depth, with real-time push (IMAP IDLE) or scheduled polling and clear progress.
• Background mail delivery, so new mail keeps arriving when the app isn't in front.
• In English, Dutch, German, French, Spanish, Italian and Portuguese, and time-zone-aware throughout.

Allodia Mail & Calendar is part of the Allodia suite: European software built so you can adopt modern tools without giving up ownership of your data or your jurisdiction.
