End User License Agreement

The same agreement that ships inside the app. It is a draft: a lawyer still has to review it before the first public release.

Last updated: November 9, 2026

Release scope: BackMyMail is sold in two ways. On this website, separate macOS and Windows editions are activated with a License Key that Polar sells as our merchant of record. The Mac App Store edition is sold by Apple and needs no License Key. Every edition includes 1,000 free message downloads; a one-time purchase unlocks unlimited archiving.

Effective date: November 9, 2026

This End User License Agreement ("Agreement") is between you and Omnibus R&D, LLC ("we", "us"). It covers the BackMyMail desktop application, including its updates and documentation (the "Software"). By installing or using the Software, you agree to this Agreement. If you do not agree, do not install or use the Software.

If you accept this Agreement on behalf of a company or other organization, you confirm that you are authorized to do so, and "you" means that organization.

1. Definitions

  • "License Key" means the key you receive when you buy a license for the Software on our website.
  • "Major Version" means all releases of the Software that share the same first version number. For example, 1.0, 1.4 and 1.9.2 all belong to Major Version 1.
  • "Computer" means a single physical or virtual computer on which the Software is installed and activated.
  • "Archive" means the copies of your email, the search index and the other files that the Software keeps in the folder you choose on your Computer.

2. Free version

Without a license, the Software downloads the first 1,000 messages of your mail free of charge. After that, it downloads no new messages until you activate a License Key, but your Archive stays readable: you can still open, search, print and export the mail you have saved, without a time limit. The free version stays free. You may not bypass the download limit by technical means.

3. License grant

Subject to this Agreement and payment of the license fee, we grant you a perpetual, non-exclusive, non-transferable license to install and use the Major Version of the Software for which you bought a License Key, including all minor and patch releases of that Major Version that we make available, on Computers that you own or control, for your personal or business purposes. The license covers the number of Computers for which you bought it, as stated in your order, and each activation uses one of them; a License Key works only on the platform (macOS or Windows) of the edition for which you bought it.

A license is a one-time purchase, not a subscription. A later Major Version is a separate product that may require a paid upgrade; we are not obliged to release one, and nothing in this Agreement entitles you to one.

4. Activation

Activating a License Key requires an internet connection. To activate, the Software sends your License Key and a randomly generated device label (not the network name of your Computer) to our license server, which checks it with our license provider, Polar. While a license is active, the Software confirms with our license server about once every seven days that the License Key is still valid. If the Software cannot reach our license server, it keeps working for up to 14 days after the last successful check.

To move your license to another Computer, choose Settings > License > Remove license from this computer on the old Computer, then enter your License Key on the new one. If you no longer have the old Computer, contact us and we will free its activation.

5. Mac App Store edition

If you got the Software from the Mac App Store, Apple sold it to you, and Apple's terms for App Store purchases govern that purchase, including payment, refunds and the devices on which you may use it. That edition is not activated with a License Key, and sections 4 and 13 do not apply to it. The rest of this Agreement applies to it to the extent it does not conflict with Apple's terms.

For that edition, you and we also agree that:

  • This Agreement is between you and us only, not Apple, and we, not Apple, are solely responsible for the Software and its content.
  • The license granted to you is limited to using the Software on Apple-branded products that you own or control, as permitted by the Usage Rules in Apple's Media Services Terms and Conditions.
  • Apple has no obligation to provide any maintenance or support for the Software.
  • If the Software fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price to you; to the maximum extent permitted by law, Apple has no other warranty obligation with respect to the Software.
  • We, not Apple, are responsible for addressing any claims by you or a third party relating to the Software or your possession and use of it, including product liability claims, claims that it fails to conform to any legal or regulatory requirement, and claims under consumer protection, privacy or similar laws.
  • If a third party claims that the Software or your possession and use of it infringes their intellectual property rights, we, not Apple, are responsible for the investigation, defense, settlement and discharge of that claim.
  • You represent that you are not located in a country that is subject to a U.S. Government embargo or that has been designated by the U.S. Government as a "terrorist supporting" country, and that you are not listed on any U.S. Government list of prohibited or restricted parties.
  • You must comply with applicable third-party terms, such as your mail provider's terms, when you use the Software.
  • Apple and its subsidiaries are third-party beneficiaries of this Agreement, and upon your acceptance of it, Apple will have the right (and will be deemed to have accepted the right) to enforce it against you as a third-party beneficiary.

6. Restrictions

You may not, and may not allow anyone else to:

  • share, publish, sell or otherwise distribute your License Key, or use it on more Computers than this Agreement allows;
  • rent, lease, lend, sell, sublicense or otherwise transfer the Software, except as allowed by applicable law;
  • reverse engineer, decompile or disassemble the Software, except to the extent that applicable law expressly permits it despite this restriction;
  • remove, bypass or interfere with the license checks or the download limit of the free version;
  • remove or change any copyright, trademark or other notices in the Software;
  • use the Software in violation of any applicable law.

7. Your mail and your responsibility

The Software downloads email from the mail accounts you connect into the Archive on your Computer. Your mail is not sent to our servers. You agree that:

  • You are responsible for having the right to access and archive every mailbox you connect, including mailboxes that belong to your employer or to other people, and for complying with any laws, policies or retention rules that apply to that mail.
  • The Archive is stored on your Computer. Its working copy and search index are not encrypted; protecting your Computer and the Archive is your responsibility.
  • You are responsible for keeping backups of your Archive. The Software can make backups and exports, but it does not keep a copy anywhere else.
  • Cleanup moves mail at your provider to the provider's Trash only after you confirm. Once your provider empties its Trash, the Software cannot bring that mail back from the provider. Check the Archive before you clean up.

8. Mail providers

The Software connects to your mail provider with IMAP or, for Gmail and Microsoft accounts, with the provider's own sign-in (OAuth). Your mail provider's terms apply to its services, including any limits it places on downloads and access. We do not control mail providers, and we are not responsible for their services, for changes they make or for their decision to block or limit access.

9. Updates

We may make updates to the Software available. Updates may add, change or remove features.

10. Privacy

The Software processes your mail only on your Computer. Our Privacy Policy, available at https://backmymail.com/privacy, describes the limited information the Software and our website handle, and is part of this Agreement. The Software sends error reports to our error-reporting provider as described in the Privacy Policy; they never include the content of your mail.

11. Open-source components

The Software includes open-source components. Each is licensed under its own terms, which are listed in the Software under Settings > About > Open source licenses. Nothing in this Agreement limits your rights under those licenses.

12. Ownership

The Software is licensed, not sold. We and our licensors own all rights, title and interest in the Software, including all intellectual property rights. All rights not expressly granted in this Agreement are reserved. Your mail, your Archive and the exports and backups you make with the Software belong to you.

13. Payment and refunds

Licenses bought on our website are sold by Polar, which acts as our reseller and merchant of record. Prices, taxes and payment are handled under Polar's terms at the time of purchase.

14. Termination

This Agreement remains in effect until it is terminated. It ends automatically if you fail to comply with any of its terms. When it ends, you must stop using the Software and delete it from your Computers; your Archive remains yours. Sections 7, 12 and 15 through 19 survive termination. We may revoke a License Key that has been refunded, charged back, shared or obtained fraudulently.

15. No warranty

THE SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITH ALL FAULTS AND WITHOUT WARRANTY OF ANY KIND. TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, WE DISCLAIM ALL WARRANTIES, WHETHER EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT AND ACCURACY. WE DO NOT WARRANT THAT THE SOFTWARE WILL DOWNLOAD OR KEEP EVERY MESSAGE, THAT IT WILL WORK WITH EVERY MAIL PROVIDER, THAT IT WILL BE UNINTERRUPTED OR ERROR-FREE, OR THAT ITS RESULTS WILL MEET YOUR REQUIREMENTS OR ANY LEGAL OR REGULATORY REQUIREMENT. Some jurisdictions do not allow the exclusion of implied warranties, so some of these exclusions may not apply to you.

16. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL WE OR OUR LICENSORS BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL OR BUSINESS, INCLUDING LOSS OF EMAIL, ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE SOFTWARE, HOWEVER CAUSED AND UNDER ANY THEORY OF LIABILITY, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

OUR TOTAL LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE SOFTWARE WILL NOT EXCEED THE AMOUNT YOU PAID FOR YOUR LICENSE, OR FIFTY US DOLLARS (US$50) IF YOU PAID NOTHING. Some jurisdictions do not allow the limitation or exclusion of liability for incidental or consequential damages, so some of these limitations may not apply to you.

17. Export and government use

You agree to comply with all export and sanctions laws that apply to your use of the Software. If you are a United States government end user, the Software is "commercial computer software" and is licensed to you only with the rights given to all other end users under this Agreement.

18. Governing law

This Agreement is governed by the laws of the jurisdiction in which we are established, without regard to its conflict of laws rules. If you are a consumer, you keep the protection of the mandatory laws of your place of residence and may bring claims in its courts. The United Nations Convention on Contracts for the International Sale of Goods does not apply.

19. General

This Agreement, together with the Privacy Policy, is the entire agreement between you and us about the Software and replaces any earlier agreements about it. If any provision is found unenforceable, the rest of the Agreement remains in effect. Our failure to enforce a provision is not a waiver. You may not assign this Agreement without our written consent; we may assign it in connection with a merger, acquisition or sale of assets. We may update this Agreement for future versions of the Software; the version that came with your release of the Software applies to it.
