Beta Mail — Privacy Policy

Your mail.
Your inbox.

Effective date: April 2026

Beta Mail is built on a simple principle: your correspondence is personal. We have designed the app so that your mail stays where it belongs — on your device and with your existing mail provider — and nowhere else.

What we collect

Beta Mail collects only what is necessary to operate the app and its optional AI features.

Mail account credentials Stored entirely on your device in the system keychain. Used only to connect directly to your mail provider over IMAP and SMTP. We never see or transmit them.
Messages, threads & attachments Held on your mail provider's server and cached locally on your device for offline access. Synced across your Apple devices via iCloud if you have it enabled. We never see this data.
AI-generated replies Generated on demand when you open a message or request a reply, and stored locally on your device until you send or discard them. Not retained by us after generation.

What we do not collect

We do not collect, store, or process any of the following:

No Beta Mail account or login Beta Mail does not require you to create an account with us. The credentials you provide are for your existing mail provider, and they stay on your device. If you opt in to sharing AI credits across your devices, an anonymous identifier is stored — but it is not linked to any personal information.
No message content The content of your inbox, sent mail, drafts, attachments, contacts, and AI-generated replies never leaves your device or the Apple ecosystem. We have no access to it.
No tracking or advertising data We do not use analytics SDKs, advertising identifiers, or any third-party tracking.
No data sharing with third parties We do not sell, rent, or share your information with any third party for any purpose.

Your mail provider

Beta Mail connects directly from your device to the IMAP and SMTP servers of the mail provider you configure. Your messages live on that provider's infrastructure and are governed by their terms and privacy policy. We are not a party to that connection and have no visibility into it.

Apple ecosystem & iCloud

Locally cached mail and app settings are stored in Apple's ecosystem using their standard sync technologies. Syncing across your devices is governed by Apple's own privacy policy and iCloud terms. We have no visibility into or access to data stored in iCloud.

451 blockchain notifications

Beta Mail supports a new class of IMAP message type that carries notifications of publications to the 451 blockchain. These notifications are delivered through the standard mail protocol and stored on your mail provider like any other message. We do not collect, track, or retain any record of which notifications your device receives or processes.

Children's privacy

Beta Mail does not knowingly collect any information from children under the age of 13. The app requires no account creation with us and does not collect personal data. The only server-side data we store is an anonymous identifier used for optional cross-device credit sharing, which contains no personal information.

Changes to this policy

If we make material changes to this privacy policy, we will update the effective date above. We encourage you to review this page periodically.
