No. There is no Open Mailbox server: the app talks directly to your provider's IMAP and SMTP servers. We never receive your mail, your password or any usage data.
Yes. No ads, no subscription, no in-app purchases. The code is open source under the Mozilla Public License 2.0.
Gmail, iCloud, Yahoo, OVHcloud and IONOS are set up in a few taps. Any other provider that offers IMAP and SMTP works too; server settings are found automatically when possible.
Not yet. Microsoft accounts need a sign-in method (OAuth) that Open Mailbox doesn't support yet. It's on the roadmap.
Your phone checks for new mail in the background. Android checks at best every 15 minutes; iOS decides how often based on how you use the app. Without a push server, new mail can show up a little later than in other apps: that's the trade-off for having nothing in between.
In your phone's secure storage: the Keychain on iPhone, the Keystore on Android. It is only ever sent to your mail provider.
Only for optional extras: contact pictures (Gravatar and the sender's company website, at most once a month per address; can be turned off), remote images when you choose to load them, and a one-time server lookup when you add a provider the app doesn't know. The full list is in the privacy policy.
Read the privacy policy →Yes. Your messages are stored on your phone, so you can read and search them without a connection. What you do offline is synced when you're back online.
