Last Updated and Effective: August 22, 2026
This Privacy Policy describes how Kirill Skobelev, Eric Fithian, and Giulio Frey (collectively, “DeSlop Arena,” “we,” “us,” or “our”) collect, use, disclose, sell, license, retain, and otherwise process information in connection with desloparena.com and its leaderboards, accounts, voting and submission features, application programming interfaces, downloads, datasets, and related services (collectively, the “Service”).
The Maintainers are based in Chicago, Illinois, United States. For purposes of applicable data-protection law, the Maintainers are the persons responsible for the processing described in this Privacy Policy unless otherwise stated.
Important Notice About Data Commercialization and Model Training. User submissions, votes, results, public usernames, and associated submission metadata may be made public, included in datasets, licensed or sold to third parties, and used by us or third parties to develop, train, test, evaluate, or improve artificial-intelligence and machine-learning models and systems. Nonpublic account email addresses and authentication information are excluded from these data-commercialization practices.
This Privacy Policy applies to information processed through or in connection with the Service. It does not apply to third-party websites, applications, models, payment processors, or other services that maintain their own privacy policies and determine their own processing practices.
As used herein, “personal information” means information that identifies, relates to, describes, is reasonably capable of being associated with, or could reasonably be linked to an individual or household, together with analogous terms such as “personal data” under applicable law. Personal information generally does not include lawfully de-identified or aggregate information or information excluded from the definition under applicable law.
Depending upon how you interact with the Service, we may collect the following categories of information:
We may collect your email address, username, account identifier, authentication-provider identifier, and information necessary to register, authenticate, secure, and administer an account. We may receive this information directly from you or from an authentication or database service provider.
We collect information you submit, transmit, generate, or otherwise make available through the Service, including votes, preferences, prompts, model outputs, test results, evaluations, labels, rankings, comments, feedback, files, public usernames, and associated submission metadata (collectively, “User Content”).
User Content is subject to the ownership assignment and other rights set forth in our Terms of Use. You should not submit sensitive personal information, confidential information, trade secrets, authentication credentials, financial information, government identifiers, or information that you are not legally entitled to disclose.
When you access or use the Service, we or our service providers may automatically collect IP address, browser type, device type, operating system, language, approximate location derived from IP address, referring and exit pages, pages or features viewed, timestamps, clickstream and interaction data, error and diagnostic information, cookie or session identifiers, and other server, security, and access logs.
If you access an API, dataset, or download, we may collect API credentials or identifiers, request and response metadata, rate-limit information, access times, files or endpoints requested, usage volume, and information reasonably necessary to administer, secure, meter, and enforce applicable license terms.
If paid features, data licenses, API plans, or other purchases are offered, we and our payment providers may collect transaction amount, plan, billing status, payment method type, billing contact information, and related records. Payment providers may collect full payment-card or bank information directly under their own terms and privacy policies. We do not intend to store full payment-card numbers ourselves.
We collect information contained in messages, support requests, legal notices, privacy requests, survey responses, and other communications you send to us, together with related contact information and metadata.
We may derive or generate rankings, scores, preferences, annotations, research findings, fraud or abuse indicators, statistical information, profiles, and other inferences from the information described above.
We may collect information:
We may process information for the following business, commercial, and research purposes:
We may process de-identified and aggregate information for any lawful purpose and may retain such information indefinitely, subject to applicable law.
We may disclose information to the following categories of recipients:
Votes, results, public usernames, rankings, User Content, submission metadata, and research outputs may be displayed publicly through the Service, APIs, downloads, publications, repositories, presentations, or datasets. Public information may be copied, indexed, cached, or redistributed by third parties outside our control.
We may disclose information to vendors and contractors that provide authentication, database, cloud hosting, content delivery, analytics, security, fraud prevention, communications, payment processing, technical support, and other services on our behalf. These providers may process information subject to their contractual obligations and their own legal duties.
We may disclose, license, sell, or otherwise provide User Content, public usernames, submission metadata, datasets, derived information, research outputs, and de-identified or aggregate information to academic researchers, research institutions, artificial-intelligence or machine-learning developers, model providers, data licensees, commercial partners, customers, sponsors, and other third parties. Such recipients may use the information for research, publication, dataset development, model training and evaluation, product development, or other commercial or noncommercial purposes, subject to applicable agreements and law.
We do not sell nonpublic login email addresses or private authentication credentials as a standalone contact list merely because a person uses the Service. We also do not disclose full payment-card information that is maintained directly by a payment provider and not received by us.
We may disclose information if we believe in good faith that disclosure is necessary or appropriate to comply with law, regulation, legal process, or governmental request; enforce agreements; investigate or prevent fraud, abuse, security incidents, or unlawful conduct; protect the rights, property, safety, or research integrity of the Service, the Maintainers, users, or others; or establish, exercise, or defend legal claims.
We may disclose information to attorneys, accountants, auditors, insurers, financial advisers, and other professional advisers subject to duties of confidentiality where appropriate.
We may disclose or transfer information in connection with the formation of an entity to own or operate DeSlop Arena or any actual or proposed financing, reorganization, merger, acquisition, sale, license, assignment, transfer of assets, insolvency, or similar transaction. Any successor may process information subject to this Privacy Policy or a successor policy as permitted by law.
We may disclose information for another purpose disclosed to you or at your direction or with your consent.
For purposes of certain privacy laws, some of the disclosures described in this Privacy Policy may constitute a “sale” or “sharing” of personal information even if no money is exchanged. In particular, we may receive monetary or other valuable consideration for licensing or providing User Content, public usernames, submission metadata, derived information, or datasets to research and commercial recipients. We and recipients may use such information for artificial-intelligence and machine-learning model development, training, testing, evaluation, and commercialization.
The categories of personal information that may be sold, shared, or licensed include:
The categories of recipients are described in Section 5.3. Nonpublic login email addresses, passwords, private authentication credentials, and full payment-card information are excluded from the foregoing data-commercialization practices unless we provide a separate, specific notice and obtain any consent required by applicable law.
Where applicable law grants a right to opt out of a sale, sharing, targeted advertising, or certain profiling, you may submit a request as described in Section 10. We will honor legally valid opt-out preference signals, including Global Privacy Control, where required by applicable law and reasonably detectable by our systems.
We do not knowingly sell or share personal information of a person under 16 where applicable law requires prior affirmative authorization. If we obtain actual knowledge that such authorization is required, we will seek the required authorization or exclude the applicable personal information from the sale or sharing.
We and our service providers may use cookies, local storage, session tokens, pixels, and similar technologies to authenticate users, maintain sessions and preferences, prevent abuse, secure the Service, remember settings, measure performance, and conduct analytics. If advertising or additional analytics technologies are introduced, we may update this Privacy Policy and provide notices, choices, or consent mechanisms required by applicable law.
You may be able to control cookies through your browser or device settings. Disabling necessary cookies or storage may prevent the Service or certain features from functioning correctly.
We retain personal information for as long as reasonably necessary to fulfill the purposes described in this Privacy Policy, administer and secure the Service, maintain research and dataset integrity, comply with legal obligations, resolve disputes, and enforce agreements. Retention periods vary according to the type of information, the purpose for processing it, contractual commitments, legal requirements, and technical considerations.
Without limiting the foregoing:
Information may persist temporarily in backups and disaster-recovery systems after deletion from active systems. We may also retain information where necessary to comply with law, establish or defend legal claims, prevent fraud or abuse, honor an opt-out, or enforce agreements.
We use administrative, technical, and organizational safeguards that we consider reasonable in light of the nature of the Service and information processed. Nevertheless, no method of transmission, storage, or security is completely secure, and we cannot guarantee absolute security. You are responsible for maintaining the confidentiality of your Account credentials and for using appropriate caution when submitting information.
Depending upon your location and applicable law, you may have the right to request access to, correction of, deletion of, or portability of certain personal information; to obtain information about our processing and disclosures; to restrict or object to certain processing; to opt out of sale, sharing, targeted advertising, or certain profiling; to withdraw consent where processing is based on consent; and to appeal a refusal to act on a request. Applicable law may provide exceptions and may permit or require us to retain certain information.
To submit a privacy request or appeal, email contact@desloparena.com with the subject line “Privacy Request.” Please describe the right you seek to exercise and the information or Account involved. We may request information reasonably necessary to verify your identity and authority. We will not discriminate against you for exercising a privacy right protected by applicable law.
Where permitted by law, an authorized agent may submit a request on your behalf. We may require proof of the agent’s authority and may require you to verify your identity or confirm the request directly.
Account closure or a privacy deletion request does not necessarily require deletion of information that is not personal information, information that has been lawfully de-identified or aggregated, information that we are legally permitted or required to retain, or information maintained by an independent third party. Rights granted under the Terms of Use remain effective except to the extent applicable privacy law requires otherwise.
Certain privacy laws apply only to organizations that satisfy specified jurisdictional, revenue, processing-volume, or business-model thresholds. We provide rights and opt-outs to the extent required by the law applicable to us and the requesting person.
The Service is not directed to minors, and a person under 18 may not access or use the Service, register an Account, submit User Content, or provide personal information. We do not knowingly collect personal information from persons under 18. If we obtain actual knowledge that we collected personal information from a person under 18, we will take reasonable steps to suspend the applicable access or Account and delete the information as required by law. A parent or guardian who believes a minor has provided personal information may contact us at contact@desloparena.com.
The Service is operated from the United States. If you access the Service from another jurisdiction, your information may be transferred to, stored in, and processed in the United States and other countries whose data-protection laws may differ from those where you reside.
Where the laws of the European Economic Area, United Kingdom, Switzerland, or another jurisdiction require a lawful basis for processing, we rely, as applicable, upon performance of a contract or steps taken at your request; our legitimate interests in operating, securing, researching, improving, and commercializing the Service and its datasets; compliance with legal obligations; protection of vital interests; and consent. Where required, we will implement an appropriate lawful mechanism for international transfers.
Individuals in these jurisdictions may have rights to access, rectify, erase, restrict, or object to processing; receive portable information; withdraw consent; and complain to a competent supervisory authority. These rights are subject to applicable conditions and exceptions and may be exercised as described in Section 10.
The Service may rely upon or link to third-party authentication, database, hosting, payment, analytics, model, advertising, or other services. Those third parties may collect and process information under their own privacy policies and legal responsibilities. We do not control and are not responsible for independent third-party privacy practices.
We may amend this Privacy Policy from time to time. We will post the revised policy and update the “Last Updated and Effective” date. If a change materially affects registered users or materially expands how we use or disclose previously collected personal information, we will provide additional notice or obtain consent where required by applicable law. Your continued use of the Service after the effective date of a revised policy constitutes acknowledgment of the revised policy but does not constitute consent where applicable law requires a different form of consent.
Questions, legal notices, and permission requests may be sent to contact@desloparena.com.
Privacy requests should include the subject line “Privacy Request.”
