Last updated: 4 November 2026

1. Who is responsible

Backup4Mail (“the app”) is developed and published by Robert Poetzsch under the robspace brand.

This policy describes which data Backup4Mail processes, where it is kept and who can see it. It applies to the Backup4Mail app for Mac and to this website. Backup4Mail is in development; this policy describes the current test version.

2. Summary

  • Backup4Mail has no server of its own. robspace operates no service that your mail, your passwords or your account data pass through.
  • Your mail goes only from your mail server to the destination you choose (a folder on your Mac, an external drive or a network drive). robspace cannot see your mail.
  • Account data stays in the app’s container on your Mac; passwords stay in the keychain of this Mac and are not synced via iCloud.
  • Backup4Mail contains no analytics, no tracking, no ads and no third-party SDKs.
  • Purchases are handled by Apple. robspace receives no payment or account data.

3. What Backup4Mail stores on your Mac

In the app’s container (~/Library/Containers/RobEarth.Backup4Mail): your backup jobs with the email address, the mail server, the user name and their settings (schedule, folders, notifications, thinning), the chosen destination as a security-scoped bookmark of macOS, a local index of your vaults (a cache built from the vault, for time travel and search) and a temporary buffer for mails that are waiting for the destination. App-wide settings are stored there as well.

In the keychain of this Mac: the password or app password of each account, for Microsoft accounts the sign-in token. The entries can only be read on this Mac and are not synced via iCloud Keychain.

4. Your mail

Backup4Mail connects directly to your mail server. The connection is always encrypted; if encryption is not possible, Backup4Mail does not connect. While backing up, Backup4Mail only reads: it marks nothing as read and moves or deletes nothing on the server.

The mails go from your mail server to the destination you choose and nowhere else: into a vault, a folder that you select on your Mac, an external drive or a network drive. When you restore, mails go from a vault or an imported file to the mail account you choose. When you export, Backup4Mail writes files to the folder you choose. robspace has no access to any of this.

The vault and its files belong to you. If your destination is a network drive, a NAS or a folder that another service syncs, the conditions of that device or service apply.

5. Setting up an account

To find the server for your email address, Backup4Mail first uses a list of well-known providers built into the app. If your provider is not on it, the app looks up the domain of your email address in DNS (MX and SRV records) and asks for your provider’s configuration file at addresses under that domain (autoconfig.<domain> and <domain>/.well-known/autoconfig/). Only the domain is used for this, never your password. The DNS queries go to the DNS server your Mac uses.

Microsoft (Outlook.com, Microsoft 365), when you connect with “Sign in with Microsoft”: signing in happens directly at Microsoft. The app receives a sign-in token and stores it in the keychain of your Mac. Microsoft’s privacy policy applies.

6. Purchases and Backup4Mail Pro

Backup4Mail can be used for free for 30 days; after that, new backups and time travel need Backup4Mail Pro (monthly or yearly subscription, or a one-time lifetime purchase). Restore and export stay free.

Purchases and subscriptions are handled entirely by Apple through the App Store and your Apple Account. Your payment details stay with Apple; Backup4Mail never sees them, and robspace receives no payment or account data (no name, no email address, no Apple Account). For the start of the trial, the app reads the date signed by Apple from Apple’s receipt on your Mac and stores it in the keychain of this Mac. Whether you own Backup4Mail Pro, the app checks on your Mac with Apple’s StoreKit. robspace operates no server that checks purchases. Apple’s terms and privacy policy apply to purchases.

7. Notifications, menu bar and login item

Backup4Mail can notify you, for example when a backup failed, when the destination has been unreachable for a while, when unusually many mails disappeared from the server or, if you switch it on, when a backup finished. You choose this per backup job. These notifications are created by the app on your Mac; there is no push service. You can switch them off in System Settings › Notifications › Backup4Mail.

With its window closed, Backup4Mail keeps running as an icon in the menu bar so that scheduled backups can run. It opens at login only if you switch that on in the app; you can remove it again there or in System Settings › General › Login Items & Extensions.

8. No analytics, no tracking, crash reports

Backup4Mail contains no analytics, tracking, advertising or crash SDKs and no third-party code that sends data. It does not track you across apps or websites of other companies and does not use an advertising ID.

Crash reports reach the developer only through Apple and only if you have agreed to share them with app developers (System Settings › Privacy & Security › Analytics & Improvements). You control that there.

9. Links

The app links to this website, to this privacy policy, to Apple’s terms of use, to subscription management in the App Store, to the robspace community page on github.com and to the support address support@robspace.de. A click opens the page in your browser or your mail app; Backup4Mail itself sends nothing. GitHub’s privacy policy applies on GitHub. Issues on GitHub are public: please do not post mail content, addresses or other personal data there.

10. Deleting data

If you remove a backup job in the app, Backup4Mail deletes its data on this Mac (schedule, folders, settings) and the account’s password or sign-in token in the keychain, unless another backup job uses the same account. The backups at the destination stay with you: Backup4Mail does not touch the vault, and you can delete it in the Finder if you want to. If you move Backup4Mail to the Trash, its container in ~/Library/Containers/RobEarth.Backup4Mail remains until you delete it.

11. This website

This website is hosted by Hetzner Online GmbH on a server in a data centre in Falkenstein (Germany). When you open a page, the web server automatically logs your IP address, the date and time, the page or file requested, the HTTP status, the amount of data transferred, the referring page (referrer) and your browser’s user agent. These logs serve only the operation and security of the website; the legal basis is Art. 6(1)(f) GDPR (legitimate interest in secure and stable operation). They are deleted automatically after 14 days at the latest, are not analysed and are not passed on unless a legal obligation requires it.

The website sets no cookies, uses no analytics or tracking and embeds no third-party content. If the website remembers a choice you make on it (for example the language), it does so only in your browser’s local storage and not for tracking. The fonts come from this server; there is no connection to Google Fonts or other font services.

12. Legal bases and your rights

The app sends no data to the developer. Processing in the app takes place on your Mac, under your control and on your instruction (Art. 6(1)(b) GDPR: providing the functions you use). Apple’s privacy policy applies to the App Store and to crash reports shared through Apple.

If you write to us at support@robspace.de, we process your message in order to answer it (Art. 6(1)(b) or (f) GDPR) and delete it once it has been dealt with and no retention obligation applies.

You have the right of access, rectification, erasure, restriction of processing, data portability and objection (Art. 15–21 GDPR), and the right to lodge a complaint with a data protection supervisory authority, for example the Hessian Commissioner for Data Protection and Freedom of Information (HBDI). As we receive no data from the app, you can exercise most of these rights directly on your Mac: change or remove accounts in the app and delete vaults in the Finder.

13. Changes

If the way the app handles data changes, we update this policy and the date at the top.
