Terms and Conditions

Effective April 23, 2026 · Last updated April 23, 2026

These Terms and Conditions ("Terms") govern your download, installation, and use of the BlurShare macOS application ("BlurShare", the "App", "we", "us", or "our"), provided by Cantina Labs ("the Company"). By installing or using BlurShare, you agree to be bound by these Terms. If you do not agree, do not install or use the App.

1. License

Subject to your compliance with these Terms, the Company grants you a limited, non-exclusive, non-transferable, revocable license to install and use BlurShare on any Apple-branded device that you own or control, as permitted by the Apple Media Services Terms and the Mac App Store Usage Rules.

This license does not permit you to:

Copy, modify, or create derivative works of the App.
Reverse engineer, decompile, or disassemble the App, except as permitted by applicable law.
Rent, lease, lend, sell, sublicense, or redistribute the App.
Remove or alter any proprietary notices or labels in the App.

2. Purpose of the App

BlurShare is a privacy utility that visually obscures ("blurs") windows, notifications, and screen regions on your Mac to help reduce the risk of accidental disclosure during screen sharing and screen recording. BlurShare is a helpful safeguard — not a guarantee. See Section 6.

3. System Permissions

To function, BlurShare requests certain macOS permissions, which may include:

Screen Recording — required to read window metadata so it can position blur overlays correctly.
Accessibility — required to detect window positions, active applications, and respond to global hotkeys.
Notifications — optional, used to display status messages.

Permissions may not always be required. You may revoke these permissions at any time in System Settings. Revoking permissions may disable some or all features.

4. User Responsibilities

You are responsible for:

Configuring allowlists, blocklists, and profiles appropriately for your use case.
Verifying that BlurShare is active and functioning correctly before sharing your screen.
Complying with all laws, employer policies, and third-party service terms that apply to your screen sharing or recording activity.

5. Updates

The Company may release updates, patches, or new versions of BlurShare from time to time. Updates may be required for continued use. Updates are delivered through the Mac App Store subject to Apple's update mechanisms.

6. Disclaimer of Warranties

BLURSHARE IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, OR UNINTERRUPTED OPERATION.

IMPORTANT: BlurShare is a privacy-assisting tool. It cannot guarantee that every sensitive surface on your screen will be hidden at all times. Operating system behavior, third-party apps, timing, permission states, edge-case display configurations, and user misconfiguration can all affect what is visible to observers. You remain solely responsible for what appears on your screen during any share, stream, or recording.

7. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE COMPANY SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR PRIVACY, ARISING OUT OF OR RELATING TO YOUR USE OF OR INABILITY TO USE BLURSHARE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

THE COMPANY'S TOTAL AGGREGATE LIABILITY SHALL NOT EXCEED THE AMOUNT YOU PAID (IF ANY) FOR BLURSHARE IN THE TWELVE (12) MONTHS PRECEDING THE CLAIM, OR FIVE U.S. DOLLARS (USD $5.00), WHICHEVER IS GREATER.

Some jurisdictions do not allow the exclusion or limitation of certain damages, so some of the above may not apply to you.

8. Third-Party Services

BlurShare may interoperate with third-party applications (such as video conferencing, streaming, or browser software) solely for the purpose of reading window state. The Company is not affiliated with, endorsed by, or responsible for those third parties or their content.

9. Termination

These Terms remain in effect until terminated. The Company may suspend or terminate your license if you materially breach these Terms. Upon termination, you must stop using the App and delete all copies.

10. Apple-Specific Terms

You acknowledge that these Terms are between you and the Company only, not with Apple, and that Apple is not responsible for the App or its content. Apple has no obligation to provide maintenance or support for the App. In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) to you; to the maximum extent permitted by law, Apple has no other warranty obligation with respect to the App. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce them against you.

11. Export Compliance

You may not use or export BlurShare in violation of U.S. export laws or the laws of your country.

12. Governing Law

These Terms are governed by the laws of the State of Arizona, United States, without regard to its conflict of laws provisions. Any dispute shall be resolved in the state or federal courts located in Maricopa County, Arizona, and you consent to the personal jurisdiction of those courts.

13. Changes to These Terms

We may update these Terms from time to time. Continued use of BlurShare after an update constitutes acceptance of the revised Terms. Material changes will be noted in the App's release notes or on our website.
