End-User License Agreement

Last updated: 19 September 2026

This End-User License Agreement ("EULA") is a legal agreement between you ("you", "Licensee") and Yehuda Ben David ("we", "us", "Licensor"), the developer of the TabBar for Office application for macOS and of its predecessors TabBar for Word, TabBar for Excel and TabBar for PowerPoint (each, the "Software").

By installing, copying, or otherwise using the Software, you agree to be bound by this EULA. If you do not agree, do not install or use the Software.

1. Licence grant

Subject to your payment of the applicable license fee and ongoing compliance with this EULA, we grant you a non-exclusive, non-transferable, revocable licence to:

  • Install and use the Software on as many Macs that you own or control as your license key allows — at least three (3)
  • Use the Software for your personal or internal business purposes

A license opens the Microsoft Office application it was bought for — Word, Excel or PowerPoint — or all three, when bought as the bundle. A license for one application does not grant rights to the others; further licenses can be added to the same installation. A license bought for TabBar for Word, TabBar for Excel or TabBar for PowerPoint opens the same application in TabBar for Office.

2. Restrictions

You agree not to:

  • Copy or distribute the Software, except for a single backup copy for archival purposes
  • Sell, rent, lease, sublicense, or transfer the Software or your license to a third party (except as expressly permitted in section 3)
  • Reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code or underlying algorithms of the Software, except to the extent this restriction is prohibited by applicable law (in which case you must notify us in advance and accept any limitations we propose)
  • Modify, adapt, or create derivative works of the Software
  • Remove, alter, or obscure any copyright, trademark, or other proprietary notice in the Software
  • Use the Software to develop a competing product
  • Bypass or attempt to bypass the license-validation mechanism
  • Use the Software in violation of any applicable law or regulation

3. Licence transfer between your devices

You may deactivate a license on one Mac and reactivate it on another, as long as the total number of active devices does not at any time exceed the number your license key allows. The deactivation feature is available through the Software or by contacting support@bdtech.app.

4. Ownership

The Software is licensed, not sold. We and our licensors retain all right, title, and interest in and to the Software, including all intellectual property rights. This EULA grants you only the rights expressly stated. All other rights are reserved.

5. Updates

We may, at our discretion, provide updates, bug fixes, and improvements to the Software. Updates are made available to all licensed users at no additional charge for the duration of the license, subject to compatibility with current macOS versions. We may discontinue support for older macOS versions with reasonable notice.

6. Licence validation

The Software periodically connects to Lemon Squeezy's license-validation service to verify that your license is active and that the device limit is not exceeded. The data exchanged in this process is described in our Privacy Policy. If license validation fails (for example, if the license has been refunded, revoked for breach of this EULA, or the device limit is exceeded), the Software may stop functioning.

7. Term and termination

This EULA takes effect when you install the Software and continues until terminated.

You may terminate this EULA at any time by uninstalling the Software and deactivating your license. If you have already paid for a license, deletion does not entitle you to a refund except as required by Lemon Squeezy's refund policy or applicable consumer-protection law.

We may terminate this EULA immediately if you materially breach it (including the restrictions in section 2). Upon termination you must stop using the Software and uninstall all copies. Sections 4 and 8–12 survive termination.

8. No warranty

THE SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING (TO THE EXTENT PERMITTED BY LAW) WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND ACCURACY.

We do not warrant that the Software will be uninterrupted, error-free, or compatible with every macOS version, hardware configuration, or third-party software (including Microsoft Word, Microsoft Excel and Microsoft PowerPoint).

Some jurisdictions do not allow the exclusion of certain warranties. To the extent we cannot lawfully disclaim a warranty, our liability is limited as set out in section 9.

9. Limitation of liability

TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, IN NO EVENT WILL WE BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, OR GOODWILL, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF THE SOFTWARE.

Our total aggregate liability for any claim arising out of or in connection with this EULA will not exceed the amount you actually paid for the Software in the twelve months preceding the claim.

Nothing in this EULA limits liability that cannot lawfully be limited, including liability for fraud, gross negligence, death, or personal injury caused by negligence.

10. Third-party software

The Software is designed to integrate with Microsoft Word, Microsoft Excel and Microsoft PowerPoint. We are not affiliated with, endorsed by, or sponsored by Microsoft Corporation. "Microsoft", "Word", "Excel", and "PowerPoint" are trademarks of Microsoft Corporation.

The Software may also use open-source components. The respective open-source licences are reproduced in the "Acknowledgements" section of the Software or provided on request.

11. Export and sanctions

You may not use, export, or re-export the Software in violation of any applicable export-control or sanctions law, including the regulations of the United States, the European Union, the United Kingdom, or Israel.

12. Governing law

This EULA is governed by the laws of the State of Israel, without regard to its conflict-of-laws rules. The competent courts of Tel Aviv-Yafo will have exclusive jurisdiction, except that consumers in the European Union and other jurisdictions may have the right to bring proceedings in their place of residence under applicable mandatory law.

13. Severability and entire agreement

If any provision of this EULA is held unenforceable, the remaining provisions will continue in full force. This EULA, together with our Privacy Policy and Terms of Service, constitutes the entire agreement between you and us regarding the Software.
