Terms of Service

Last updated: April 1, 2026

1. Acceptance of Terms

By accessing or using Polydouble ("the Platform", "we", "us"), you agree to be bound by these Terms of Service. If you do not agree with any part of these terms, you must not use this platform. These terms apply to all visitors, users, and anyone else who accesses the platform.

We reserve the right to modify these terms at any time. Continued use of the platform following any changes constitutes acceptance of the revised terms. Material changes will be communicated via an update to the "Last updated" date above.

2. Description of Service

Polydouble is a prediction market trading terminal that aggregates publicly available data from Polymarket via its CLOB and Gamma APIs. The platform provides:

— Real-time and historical price data for Polymarket prediction markets

— Order book visualisation and trade feed data

— Charting tools powered by TradingView Lightweight Charts

— A leverage trading UI simulation layer with position calculators

— Market discovery and filtering tools

In its current phase, Polydouble does not execute real trades, hold user funds, or operate a financial exchange. The leverage functionality is a simulation interface only. All trade execution takes place on Polymarket's platform, not on Polydouble.

3. Eligibility

You must be at least 18 years of age to use this platform. By using Polydouble, you represent that you are of legal age in your jurisdiction, that you have the legal capacity to enter into these terms, and that your use of this platform complies with all applicable laws and regulations in your country or region.

Residents of jurisdictions where prediction market trading, leveraged trading, or related activities are prohibited are not permitted to use this platform. You are solely responsible for determining the legality of your use.

4. Prohibited Use

You agree not to use this platform to: attempt to gain unauthorised access to any part of the system or its data sources; scrape, crawl, or otherwise extract data in ways that impose unreasonable load; distribute malware or engage in any activity that could damage or impair the platform; use the platform for any unlawful purpose; or attempt to reverse-engineer any aspect of the platform's operation.

5. Intellectual Property

The Polydouble platform, including its design, code, branding, and original content, is the intellectual property of Polydouble and its contributors. Market data displayed on the platform originates from Polymarket and is subject to Polymarket's own terms and licensing.

You may not reproduce, distribute, or create derivative works from Polydouble's proprietary content without express written permission.

7. Disclaimer of Warranties

The platform is provided "as is" and "as available" without any warranty of any kind, express or implied. We do not warrant that the platform will be uninterrupted, error-free, or free of inaccuracies. Market data is sourced from third-party APIs and may contain delays, gaps, or errors that are outside our control.

8. Limitation of Liability

To the fullest extent permitted by applicable law, Polydouble and its contributors shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of or inability to use the platform. This includes but is not limited to losses arising from trading decisions made based on data displayed on the platform, liquidations, or platform downtime.

9. Third-Party Services

This platform interfaces with Polymarket's public API. Your use of Polymarket's platform is governed by Polymarket's own Terms of Service. Polydouble has no affiliation with, endorsement from, or responsibility for Polymarket's platform, policies, or operations.

10. Governing Law

These terms are governed by and construed in accordance with applicable law. Any disputes arising in connection with these terms shall be subject to the exclusive jurisdiction of the courts in the relevant jurisdiction.
