Terms of Service
These terms govern your use of the MailArc application and of this website.
Last updated: 31 August 2026
What MailArc is
MailArc is software that imports mail from a mailbox you control and stores it as an archive on your own device. It is provided by Jens Rehpöhler, Gütersloh, Germany — see the Impressum. It is not a hosted service: there is no account, and the developer operates no server that receives your mail.
Using it
You may use MailArc only with mailboxes you own or are authorised to access, and only in compliance with applicable law and with the terms of the mail provider concerned — including Google's terms where a Gmail mailbox is involved. You are responsible for obtaining any consent that the mail in a shared or organisational mailbox may require.
You supply your own API credentials, including your own Google OAuth client. Any quota, cost or obligation attaching to those credentials is yours.
Your data and your device
The archive lives on your device and remains yours. Keeping it safe — backups, disk encryption, access control — is your responsibility, as it is for any other file you hold. How data is handled is described in the Privacy Policy.
Licence
MailArc is open-source software released under the MIT licence. The licence text accompanies the source code and governs your rights to use, copy, modify and distribute it. Where these terms and the MIT licence differ on those rights, the licence prevails.
No warranty
The software is provided "as is", without warranty of any kind, express or implied, including but not limited to the warranties of merchantability, fitness for a particular purpose and non-infringement. It is not a certified or audit-proof archiving system, and no guarantee is given that an archive is complete, uncorrupted or admissible for any legal or regulatory purpose. Do not rely on it as your only copy of anything you cannot afford to lose.
Liability
To the extent permitted by law, the developer is not liable for any claim, damage or other liability arising from the software or its use, including data loss. Liability for injury to life, body or health, and liability under the German Product Liability Act, remain unaffected, as does liability for intent and gross negligence.
Changes
These terms may be updated as the software changes. The date above always reflects the current version.
Governing law
German law applies, excluding its conflict-of-law rules and without depriving a consumer of the protection of mandatory provisions of their country of residence.
