Terms of Use

Uller is a sandbox for evaluating a perpetuals trading interface. It is not an exchange, broker, dealer, or money services business. Nothing on Uller routes, matches, or settles a real order. Account balances, positions, fills, funding payments, and PnL are bookkeeping entries inside the application and have no monetary value.

The simulated state of any account may be reset, recalculated, or deleted at any time, without notice, including on routine redeploys or maintenance. You should not rely on Uller to preserve historical trading data.

To use Uller you must be at least 18 years old and legally able to enter into a binding agreement in your jurisdiction. You may not use Uller if you are located in, ordinarily resident in, or otherwise subject to the jurisdiction of any country, region, or person targeted by comprehensive sanctions administered by the United States, the United Kingdom, the European Union, or the United Nations, or if you appear on any applicable restricted-party or sanctions list.

Nothing displayed on Uller is investment, trading, tax, legal, or other professional advice. Simulated balances, simulated PnL, leaderboards, charts, and any commentary are illustrative only and are not a forecast, recommendation, or solicitation. You are solely responsible for any decisions you make outside the simulator.

By accessing Uller you agree not to:

• Scrape, mirror, or republish Uller content for resale or for a competing product.
• Send automated traffic that abuses the API, exceeds published rate limits, or attempts to circumvent rate limiters, authentication, or per-account scoping.
• Probe, reverse-engineer, or attack the service, its underlying infrastructure, or the simulated matching engine in a way that interferes with availability or integrity for other users.
• Impersonate another person, misrepresent your affiliation with any individual or organization, or use the simulator to defraud anyone.
• Submit content that is unlawful, infringing, defamatory, or that violates the rights of any third party.

Authentication is provided by Privy. Uller does not custody private keys and does not transact on a blockchain on your behalf. Connecting a wallet through Privy proves control of an identifier; it does not move funds and does not authorize any real trade. You may disconnect your wallet from Privy at any time, which terminates the authenticated session.

You are responsible for the security of any wallet, email, or other credential you use to authenticate. We are not responsible for losses that result from a compromised credential outside our service.

The Uller name, interface, copy, code, and design are owned by Uller and its licensors. You receive a limited, revocable, non-exclusive, non-transferable right to access the simulator for personal evaluation. You do not receive any other rights by implication or otherwise.

If you submit feedback, bug reports, or suggestions, you grant Uller a non-exclusive, royalty-free, worldwide license to use that feedback to improve the product, with no obligation to compensate you.

Market data is sourced from public Coinbase Exchange and GeckoTerminal APIs, subject to their respective terms. Authentication is provided by Privy, subject to Privy's terms. We are not responsible for those third-party services, their availability, accuracy, or their terms.

Uller is provided as-is and as-available, without warranty of any kind, express or implied, including without limitation any warranty of merchantability, fitness for a particular purpose, accuracy, or non-infringement. Simulated data, including mark prices, fills, funding, leaderboards, and historical state, may be inaccurate, delayed, or removed without notice.

We do not warrant that the simulator will be uninterrupted, error-free, secure, or that defects will be corrected. Use of Uller is at your own risk.

To the maximum extent permitted by law, Uller and its operators will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, goodwill, or opportunity, arising out of or related to your use of the simulator, even if we have been advised of the possibility of such damages. Because Uller is a simulator with no real settlement, no real funds are exposed and no trading losses can be incurred through the service itself.

We may suspend or terminate access to Uller, or to any account, at our discretion, with or without notice, including for suspected abuse, security risk, or violation of these terms. Sections of these terms that by their nature should survive termination will continue to apply, including intellectual property, disclaimers, and limitation of liability.

We may update these terms from time to time. Updates take effect when posted to this page, and the "Last updated" date at the top reflects the most recent revision. Continued use of Uller after an update constitutes acceptance of the revised terms.

These terms and any dispute arising out of or related to Uller are governed by the laws of the jurisdiction in which Uller is operated, without regard to its conflict-of-laws principles. The specific jurisdiction will be identified by Uller in a future update; nothing here is intended to displace mandatory consumer-protection laws that may apply where you live.
