Terms of Use

Last updated: 2026-05-11

These terms apply to the public InboxFerry website at https://www.inboxferry.com/ and to direct-download use of the InboxFerry desktop software. If you obtained InboxFerry through a different storefront (e.g. the Mac App Store), that platform’s additional terms also apply and prevail where they conflict with these.

InboxFerry is developed and operated by Florian Müller, Reinfeld, Germany. Contact and address details are on the Imprint page.

1. What InboxFerry is

InboxFerry is a local-first desktop application for backing up and migrating email between IMAP accounts. It runs on your device and communicates only with the IMAP servers you configure. It is not a hosted service and does not store your mail in the cloud.

2. License grant

InboxFerry is licensed, not sold. Subject to these terms and payment of the applicable license fee, Florian Müller grants you a personal, non-exclusive, non-transferable, revocable license to install and use one copy of InboxFerry on devices you own or control.

You may not:

• Reverse-engineer, decompile, or disassemble the software.
• Remove or alter copyright notices or license headers.
• Redistribute, sublicense, resell, or rent the software to any third party.
• Use the software for any unlawful purpose.

3. Trial mode

The unactivated build of InboxFerry runs in trial mode, which limits each run to 100 messages. No purchase is required to evaluate the software within this limit.

4. Purchases and activation

Direct-download licenses are sold through Paddle. Payment and checkout are handled by Paddle under Paddle’s own terms. Florian Müller is the merchant of record.

After a successful purchase, a signed license file is issued and must be installed locally through the Settings view in the app. The Mac App Store edition is sold separately through Apple and does not use an external license file.

If you have a billing dispute relating to a Paddle purchase, contact Paddle support in the first instance. For licensing issues (e.g. lost license file, device migration), contact support@inboxferry.com.

5. Google OAuth

When you connect a Gmail or Google Workspace account, InboxFerry initiates a Google OAuth 2.0 authorization flow in your browser. By completing that flow you authorize InboxFerry to access your Gmail IMAP interface on your behalf. You may revoke that authorization at any time through Google Account Permissions. Revocation does not affect previously created local backups.

InboxFerry’s use of Google account data is governed by the Google API Services User Data Policy and is described in the Privacy Policy.

6. Website use

You may access the public website only for lawful purposes. You may not attempt to probe, scan, or disrupt the availability of the site or its hosting infrastructure.

7. Intellectual property

All rights in InboxFerry (software, documentation, website, trademarks, and visual assets) are owned by Florian Müller unless otherwise noted. These terms do not transfer any intellectual property rights to you.

8. Disclaimer of warranties

To the fullest extent permitted by applicable law, InboxFerry is provided “as is” without warranty of any kind, express or implied, including but not limited to warranties of merchantability, fitness for a particular purpose, or non-infringement.

Email backup involves interactions with third-party mail servers outside Florian Müller’s control. You are responsible for verifying backup completeness and maintaining independent copies of critical data.

9. Limitation of liability

To the fullest extent permitted by applicable law, Florian Müller shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including loss of data, arising from use of or inability to use InboxFerry, even if advised of the possibility of such damages.

Where liability cannot be excluded by law (e.g. under German product liability law or for damages caused by wilful misconduct or gross negligence), that liability is not limited by these terms.

10. Governing law and jurisdiction

These terms are governed by the laws of the Federal Republic of Germany, excluding its conflict-of-law provisions. The UN Convention on the International Sale of Goods (CISG) does not apply.

If you are a consumer resident in the European Union, you additionally benefit from any mandatory consumer-protection provisions of the law of your country of residence that cannot be derogated from by agreement.

For consumers in the EU, the European Commission provides an online dispute-resolution platform at https://ec.europa.eu/consumers/odr/. Florian Müller is not obliged to participate in alternative dispute resolution proceedings and does not currently do so.

11. Changes to these terms

Material changes will be reflected by updating the “Last updated” date at the top of this page. Continued use of the software or website after a change constitutes acceptance of the revised terms.
