End User License Agreement
Last updated: June 23, 2026
This End User License Agreement ("Agreement") is a legal agreement between you and Stoneshero LLC for the MyMac software application, including all updates and documentation ("Software"). By installing or using the Software, you agree to this Agreement.
1. Grant of license
Subject to your compliance with this Agreement and payment of applicable fees, we grant you a personal, non-exclusive, non-transferable, revocable license to install and use the Software on up to nine (9) Macs that you own or control.
2. License tiers and upgrades
- A current major license permits use of the major version current at time of purchase and all minor updates within it.
- A lifetime license additionally permits use of all future major versions at no further charge.
- Use of a new major version under a current-major license requires a paid upgrade.
3. Trial
Any trial version is licensed for evaluation only and may cease functioning when the trial period ends.
4. Restrictions
You may not:
- copy (except for reasonable backups), sell, rent, lease, or sublicense the Software;
- distribute or make the Software available over a network where it could be used by multiple devices beyond your licensed seats;
- reverse engineer, decompile, or disassemble the Software, except to the extent permitted by law;
- circumvent, disable, or interfere with license validation, activation limits, or the update mechanism;
- remove or alter any proprietary notices.
5. 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.
6. Updates
The Software may automatically check for, download, and install signed updates. Updates are governed by this Agreement unless accompanied by a separate license.
7. Termination
This license terminates automatically if you breach it, or upon a refund of your purchase. On termination you must stop using and remove the Software.
8. Data integrity, backups, and assumption of risk
The Software includes features that read from, write to, modify, organize, clean up, or otherwise operate on files, volumes, storage devices, and file systems — including read/write support for non-native or third-party file systems such as NTFS, ext4, XFS, and Btrfs. These operations are inherently risky and may — whether through software defects, hardware faults, power loss, file-system incompatibilities, interrupted operations, or improper use — result in the corruption, loss, or unrecoverability of data, or in a device or volume becoming unmountable or inaccessible.
You acknowledge and accept these risks and use such features at your own risk. You are solely responsible for maintaining complete, current, and verified backups of your data, and we strongly recommend that you back up any important data before performing any file-system or storage operation. To the maximum extent permitted by law, we are not responsible for any loss of or damage to data, file systems, volumes, or storage devices arising from your use of the Software.
9. Disclaimer of warranties and limitation of liability
THE SOFTWARE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. STONESHERO LLC DOES NOT WARRANT THAT THE SOFTWARE WILL BE ERROR-FREE OR UNINTERRUPTED, OR THAT IT WILL PRESERVE, PROTECT, OR CORRECTLY READ OR WRITE YOUR DATA OR FILE SYSTEMS.
TO THE MAXIMUM EXTENT PERMITTED BY LAW, STONESHERO LLC AND ITS SUPPLIERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF OR DAMAGE TO DATA, FILE SYSTEMS, VOLUMES, OR STORAGE DEVICES, LOSS OF PROFITS, OR BUSINESS INTERRUPTION, ARISING FROM OR RELATING TO THE SOFTWARE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. OUR TOTAL CUMULATIVE LIABILITY FOR ALL CLAIMS WILL NOT EXCEED THE AMOUNT YOU PAID FOR THE SOFTWARE.
Some jurisdictions do not allow the exclusion of certain warranties or the limitation of certain damages, so some of the above may not apply to you. Nothing in this Agreement excludes or limits liability that cannot be excluded or limited under applicable law, or any statutory rights you have as a consumer.
10. Indemnification
To the maximum extent permitted by applicable law, you agree to indemnify, defend, and hold harmless Stoneshero LLC and its members, officers, and agents from and against any third-party claims, damages, liabilities, losses, and expenses (including reasonable legal fees) arising out of or relating to: (a) your misuse of the Software; (b) your violation of this Agreement or any applicable law; or (c) your use of the Software with data, devices, or file systems that you do not own or are not authorized to access. This obligation does not apply to the extent a claim results from our own gross negligence or willful misconduct, and it does not require you to indemnify us beyond what is permitted by any mandatory consumer-protection law that applies to you.
11. Open-source notices
The Software includes third-party open-source components, each provided under its own license; see our Acknowledgments.
12. Governing law
This Agreement is governed by the laws of the State of Wyoming, USA, consistent with our Terms of Service, and does not limit any statutory rights you may have that cannot be excluded under applicable law.
