Policy

Terms of Service

Last updated May 16, 2026.

These terms govern your purchase and use of Refractions. By buying a license you agree to them. The refund policy is in a separate page so you can read it without scrolling — see refractions.app/refund.

1. Parties

“Refractions”, “we”, “us” refers to Devmo Solutions, 181 Miles Standish Dr, Marlborough, MA 01752, United States. “You” refers to the person or organization that purchased the license. “The Software” refers to the Refractions desktop application, the daemon it runs as a background service, and the Office add‑in.

2. License grant

Subject to your compliance with these terms and timely payment of the applicable fees, we grant you a perpetual, worldwide, non‑exclusive, non‑transferable license to install and use the Software:

  • On the number of Macs allowed by the tier you purchased: 1 Mac for the Individual tier, 5 Macs for the Lab tier.
  • For the current major version of the Software, and any minor releases or patches we issue within that major version.
  • For your own internal use, or for use by your employees, students, or research group members in the case of a Lab license.

Future major versions of the Software (for example, a hypothetical Refractions 2.0) may require a separate purchase. We will not retroactively disable a license you already paid for.

3. What you may not do

You must not:

  • Reverse engineer, decompile, or disassemble the Software, except to the extent applicable law expressly permits despite this restriction.
  • Resell, sublicense, rent, lease, or otherwise distribute the Software or your license key.
  • Use the Software to circumvent the licensing or activation of any third‑party product, including GraphPad Prism.
  • Use the Software in violation of any applicable law.

4. License keys and activations

Each license is tied to a key. The Software validates the key on first activation and every 24 hours afterward. The license tier sets a hard limit on the number of concurrent machine activations. If you need to move a license to a new Mac (for example because your old Mac broke), email support@refractions.app and we will release the old seat.

We reserve the right to revoke a license key if we determine, with reasonable evidence, that it is being shared beyond the seat count, used in violation of these terms, or obtained through chargeback fraud.

5. Updates

We may release updates to the Software, including security fixes, bug fixes, and new features. Updates inside the same major version are included with your license at no additional cost. We are not obligated to release any particular update.

6. Third‑party software

Refractions is not affiliated with, endorsed by, or sponsored by GraphPad Software, Inc. or Microsoft Corporation. GraphPad Prism, PowerPoint, Word, and Excel are trademarks of their respective owners. Your use of those products is governed by their own license terms.

7. Privacy

Our handling of your personal data is described in the privacy policy.

8. Warranty disclaimer

The Software is provided “as is” and “as available”, without warranty of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose, and non‑infringement, to the maximum extent permitted by law.

We do not warrant that the Software will be uninterrupted, error‑free, or compatible with every version of GraphPad Prism, macOS, or Microsoft Office. Keep backups of files you edit.

9. Limitation of liability

To the maximum extent permitted by law, our total liability for any claim arising out of or relating to the Software or these terms is limited to the amount you paid for your license in the twelve months preceding the claim. We will not be liable for indirect, incidental, consequential, special, or punitive damages, including loss of data, loss of profit, or business interruption, even if we have been advised of the possibility of such damages.

Nothing in these terms limits liability for fraud, death, personal injury, or any other liability that cannot be limited under applicable law.

10. Indemnification

You agree to indemnify and hold us harmless from any claim brought by a third party arising out of your breach of these terms or your unlawful use of the Software.

11. Termination

You may stop using the Software and request a refund per the refund policy at any time. We may terminate your license if you materially breach these terms; we will give you reasonable notice and an opportunity to cure where the breach is curable.

12. Governing law and venue

These terms are governed by the laws of the Commonwealth of Massachusetts, United States, without regard to its conflict‑of‑laws rules. Any dispute will be brought in the competent courts of that jurisdiction, except where applicable consumer‑protection law gives you the right to bring proceedings in your country of residence.

13. Changes to these terms

We may revise these terms from time to time. Material changes will be announced by email to registered customers and on this page. Continued use of the Software after a change constitutes acceptance of the revised terms.

14. Entire agreement

These terms, together with the privacy policy and refund policy, are the entire agreement between you and us regarding the Software, and supersede any prior agreements on the same subject matter.
