Agreement to terms

By downloading, installing, or using the SignBridge app or website (the “Service”), you agree to these Terms of Use. If you do not agree, do not use the Service. The Service is provided by Skyline Vis (“we,” “us”).

The service is in beta

SignBridge is currently in beta. Features may change, accuracy will vary, and components may break. Translations produced by the Service are imperfect and should not be relied upon for legal, medical, safety-critical, or other high-stakes communication. Use the Service for casual, low-stakes conversations only. For critical communication, use a certified human interpreter.

Acceptable use

You agree not to:

• Use the Service to harass, intimidate, or harm others.
• Submit content (including signed contributions) that infringes anyone’s rights, depicts minors inappropriately, or violates applicable law.
• Attempt to reverse-engineer, decompile, or extract the on-device model in ways that violate the license below.
• Probe, scan, or test the vulnerability of our infrastructure without prior written consent.
• Use the Service in any way that interferes with other users or degrades availability.

Your contributions and the license you grant

When you contribute a sign, the app records and uploads abstract numerical hand-position data — not video. By contributing, you grant Skyline Vis a worldwide, non-exclusive, royalty-free, perpetual license to use that data to train and improve our models, evaluate model quality, and publish aggregate or research findings (without identifying you).

You retain ownership of your underlying signing performance. We do not claim ownership of the gestures you make — only a license to use the derived numerical data. You may revoke this license at any time by emailing us; we will delete the data tied to your device identifier within 30 days of receipt.

Disclaimers

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. WE DO NOT WARRANT THAT TRANSLATIONS WILL BE ACCURATE, THAT THE SERVICE WILL BE UNINTERRUPTED, OR THAT ERRORS WILL BE CORRECTED. NO PART OF THE SERVICE CONSTITUTES MEDICAL, LEGAL, OR PROFESSIONAL ADVICE.

Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, SKYLINE VIS, ITS OFFICERS, EMPLOYEES, AND CONTRACTORS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, OR SPECIAL DAMAGES ARISING OUT OF OR RELATED TO YOUR USE OF THE SERVICE, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. OUR AGGREGATE LIABILITY WILL NOT EXCEED THE GREATER OF (A) USD $100 OR (B) AMOUNTS YOU HAVE PAID US IN THE PRECEDING 12 MONTHS.

Termination

You may stop using the Service at any time by uninstalling the app. We may suspend or terminate your access if you violate these terms or use the Service in a way that we reasonably believe causes harm. We may also discontinue the Service entirely; we will provide reasonable advance notice before doing so.

Changes

We may update these terms. Material changes will be announced in the app and on the website. Continued use after a change constitutes acceptance.

Governing law

These terms are governed by the laws of the state in which Skyline Vis is registered, without regard to its conflict-of-laws principles. Disputes will be resolved in the courts of that jurisdiction. (Final jurisdiction language pending legal review and confirmation of registration state.)
