Terms of Service

1. The Service

Dual Canvas provides browser-based collaborative drawing features, including realtime synchronization when you join or create sessions. We may modify, suspend, or discontinue features with or without notice.

2. Eligibility

You must be legally able to enter a contract in your jurisdiction. The Service is not intended for children under 13 (or the minimum age in your country).

3. Accounts

If you create an account (present or future), you are responsible for safeguarding credentials and for activity under your account. Notify us if you suspect unauthorized access.

4. Acceptable use

You agree not to:

• Violate applicable law or infringe others’ intellectual property or privacy rights.
• Upload or transmit malware, attempt unauthorized access, or disrupt the Service (including overloading or abusing APIs or WebSocket endpoints).
• Harass, threaten, or post unlawful, defamatory, hateful, or explicit content in collaborative sessions.
• Scrape, resell, or commercially exploit the Service without our written permission.

5. User content

You retain ownership of content you create. You grant us a limited, worldwide, royalty-free license to host, process, transmit, and display your content solely to operate and improve the Service—including relaying drawing data to other participants in the same session.

Content in shared rooms may be visible to anyone with the session link or code. Do not share sensitive personal or confidential information on the canvas.

6. Advertising

We may show advertisements through partners such as Google AdSense. Advertisers’ practices are subject to their own policies. See our Privacy Policy for how cookies and similar technologies may be used.

7. Disclaimers

THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT.

8. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE AND OUR AFFILIATES, DIRECTORS, EMPLOYEES, AND SUPPLIERS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, OR GOODWILL, ARISING FROM YOUR USE OF THE SERVICE. OUR TOTAL LIABILITY FOR CLAIMS RELATING TO THE SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US FOR THE SERVICE IN THE TWELVE MONTHS BEFORE THE CLAIM OR (B) FIFTY US DOLLARS (US $50), IF YOU HAVE NOT PAID US.

9. Indemnity

You will defend and indemnify us against claims arising from your use of the Service, your content, or your violation of these Terms, to the extent permitted by law.

10. Termination

We may suspend or terminate access for conduct that violates these Terms or risks the Service or others. You may stop using the Service at any time.

11. Governing law

These Terms are governed by the laws applicable in your primary place of business or residence, excluding conflict-of-law rules, unless otherwise required by mandatory local law. Courts in that jurisdiction have exclusive venue, subject to applicable consumer protections.

You may wish to specify a single jurisdiction (e.g. your state or country of incorporation); review with counsel.

12. Changes

We may update these Terms. We will post the updated Terms on this page and update the “Last updated” date. Continued use after changes constitutes acceptance of the revised Terms, where permitted by law.
