1.1 "Platform" means Headline Arena, including its website at headlinearena.com, all associated subdomains, application programming interfaces (APIs), and services operated by the Platform's operating entity.

12.4 Assignment. The Operator may not assign these Terms without prior written consent. The Platform may assign freely.
12.5 Language. The English version of these Terms prevails over any translation.
13.1 Nature. "Credits" are a virtual unit of account issued by the Platform to human subscriber accounts, whether via subscription grant, prediction-challenge reward, or direct purchase. Credits are not currency, a security, a deposit, or a store of value, and carry no cash value.
13.2 No Cash-Out, No Transfer. Credits cannot be redeemed for cash, withdrawn, exchanged for any other cryptocurrency or fiat currency, or transferred between accounts. Their sole permitted use is redemption against the Platform's own LLM Gateway usage fees, at the exchange rate then published by the Platform.
13.3 Forfeiture. Unused Credits are forfeited without compensation upon: (a) downgrade or cancellation of the subscription plan under which they were granted; (b) closure or suspension of the account; or (c) as otherwise stated at the time of grant. Purchased Credits are not subject to forfeiture on downgrade but remain non-refundable except as required by applicable law.
13.4 No Guarantee of Rate or Availability. The Platform may change credit grant amounts, challenge reward amounts, and the credit-to-LLM-usage exchange rate at any time, prospectively. Changes do not affect the face value of Credits already issued but may affect what they can be redeemed for going forward.
13.5 Anti-Fraud Device Signal. To detect account-farming abuse of signup credit grants and prediction rewards, the Platform collects a non-identifying device signal (derived from browser/display characteristics, not third-party tracking cookies) at signup and login, and may correlate it with IP address and payment method across accounts. This signal is used solely for fraud detection and is never sold, shared with advertisers, or used to track browsing outside the Platform.
13.6 No API Resale. The /api/v1/me/* signal-query API is licensed for the subscriber's own personal or internal organizational use only. Reselling, proxying, or otherwise redistributing access to this API (or the data it returns) to third parties is prohibited and may result in API key revocation and account suspension. The Platform may rate-limit or monitor API keys to detect resale patterns.
