A brand-new Free account has a smaller starter allowance for mail to outside addresses; verifying — a quick one-time check, still free — lifts it to the full Free limits above. Everything inside Confidesk works from the first minute.

How accounts stay active

Free — getting started: register and sign in — if an account is created but never signed in to, it's removed within a week (a reminder is emailed first) so the name is freed. Once you're using it, a starter allowance covers mail with outside addresses; when it runs out, verify — a quick free check — to keep sending.
Free — keeping it: if you don't sign in for 30 days the account is paused; after another 30 days it's removed. Sign in regularly to keep it active.
Pro & Advanced: no inactivity deletion while your subscription is active.
Over your storage: if you go past your storage, you have 90 days to free up space or move to a bigger plan before the account is affected.

Confidesk can't recover your data if you lose your passphrase, and deleted accounts are gone for good.

The desktop app

Available on Pro and Advanced plans, for Mac, Linux and Windows.

The desktop app gives you everything the web app does, plus a few things only a native app can:

Search your mail — full-text search across everything stored on your device. It can't exist in the browser: the index would have to be written to disk, leaving a decrypted copy of your mailbox on the machine.
Works offline — read and write your mail without a connection; it syncs automatically when you're back online.
Bring in your other mailboxes — connect any standard email account alongside your Confidesk mail, all in one place.
Quick unlock — reopen on your own device with just your passphrase.

The iPhone app

Available on Free, Pro and Advanced plans, from the App Store.

The same Confidesk in your pocket: your key is unlocked on the phone, and everything is stored encrypted. On top of the web app it adds:

Search your mail — your mail is stored on the phone, so it can be searched instantly.
Works offline — read and write without a connection, with a visible outbox that syncs when you're back online.
Face ID unlock — quick unlock on your own phone, revocable remotely.
Push notifications — that never carry your content.
