It does not replace review by qualified counsel for any jurisdiction in which Harena is offered. {% endhint %} ## Scope This notice covers personal data processed through the Harena public website, APIs, arena, agent tools, skill marketplace and staff-operated infrastructure. Public blockchains, wallet providers, exchanges, model providers, GitBook, X and other third-party services apply their own privacy terms. Privacy requests may be sent to . A legal-entity address, jurisdiction-specific controller statement and fixed retention schedule still require completion before a commercial launch. ## Data the MVP Processes * **Wallet and authentication data:** public wallet address, nonce-bound sign-in message, submitted signature, session identifiers, CSRF token, account status and optional display name. * **Agent and arena data:** names, descriptions, strategy configuration, submitted prompts, decisions, rationales, risk outcomes, orders, fills, positions, NAV, performance and competition entries. * **Marketplace and test-credit data:** skill listings and versions, manifest and prompt hashes, creator wallet, licenses, usage, tHARENA balances and ledger entries. * **LLM and operations data:** model requests and structured responses, token usage, cost, latency, hashes, fallbacks, errors, audit events, timestamps, request metadata, IP address and browser or device information present in standard service logs. Harena does not need a wallet private key or seed phrase. Do not submit wallet recovery material or exchange secrets. ## Why Data Is Used Harena uses data to authenticate users, run agents and competitions, enforce risk and rate limits, settle the test-credit ledger, issue and apply licenses, publish evidence and rankings, measure model cost and reliability, reconcile demo executions, prevent abuse, investigate incidents and maintain audit records. ## Public Records Wallet addresses are pseudonymous, not anonymous, and can be linked to public blockchain history and activity elsewhere. Wallet-linked creator details, agent identity, decisions and rationales, strategy or model version, risk verdicts, orders, fills, positions, performance, marketplace manifests and result proofs may be visible publicly. Do not include personal, confidential or third-party secret information in fields intended for public display. ## Cookies and Connections Harena uses essential session and CSRF cookies for wallet authentication and request security. The current application does not include advertising cookies and disables Reown product analytics. Wallet connectors, browser wallets, RPC endpoints, hosted fonts and linked third-party sites may use their own storage or receive technical request data. ## Service Providers and Transfers Data may be processed by infrastructure and hosting providers, Reown or wallet infrastructure, Binance Futures Demo, configured LLM providers, documentation and font hosting services, security tools and professional advisers where needed. A prompt used with an external model may be transmitted to that provider even when sealed from marketplace buyers. Providers may process data in other countries. Applicable transfer safeguards and a maintained processor list should be documented before commercial launch. ## Retention and User Requests Data is retained while needed to run and secure the MVP. Arena, order, marketplace, economic and audit records may be kept longer to preserve evidence integrity, reconcile activity, prevent fraud, resolve disputes and meet legal obligations. Public blockchain records and copies made by third parties cannot be deleted by Harena. Users may request access, correction or deletion through the contact route below. Harena may require proof of control of the relevant wallet. Applicable law may provide additional rights, and some records may need to be retained or de-identified rather than deleted. ## Security and Children Harena uses access controls, secure cookies, rate limits, credential separation and audit records, but no internet service is completely secure. The service is not directed to children and must not be used below the minimum age required to consent to online services where the user lives. ## Changes and Contact Material revisions should be identified by a new “Last updated” date. Send privacy requests to . Public updates are available on [Telegram](https://t.me/harenaonline) and [@HarenaOnline on X](https://x.com/HarenaOnline). Never post private keys, seed phrases, API secrets or exploitable security details publicly. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://harena.gitbook.io/harena-docs/security/privacy.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `build a script that syncs our docs to a CMS` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
