Terms of Service

---

Welcome to Eyedo (the "App"), a cross-platform drawing-doodle creation, synchronization, and interactive gaming service operated by Shanghai Huatong Technology Co., Ltd. ("Eyedo", "we", "us", or "our"). These Terms of Service ("Terms") form a binding legal agreement between you and Eyedo governing your access to and use of the App, website, and associated features (collectively, the "Services").

PLEASE READ THESE TERMS CAREFULLY BEFORE USING THE SERVICES. THEY CONTAIN IMPORTANT PROVISIONS REGARDING YOUR LEGAL RIGHTS, REMEDIES, AND OBLIGATIONS, INCLUDING MANDATORY LIMITATIONS OF LIABILITY, PLATFORM SYNDICATION AND MONETIZATION RIGHTS OVER USER CONTENT, ARBITRATION AND CLASS ACTION WAIVERS, AND SERVICE DISCONTINUATION IMMUNITIES. By accessing or using the Services, you confirm that you have read, understood, and agreed to be bound by these Terms and our Privacy Policy. If you do not agree, you must immediately cease all access to and use of the Services.

1. Eligibility, Content Rating, and Minors

• Users in Mainland China: For the purposes of these Terms, Mainland China excludes the Hong Kong Special Administrative Region, Macao Special Administrative Region, and Taiwan region. The Services are not provided in Mainland China. We do not provide online operation services or minor accounts/anti-addiction services in Mainland China, nor do we knowingly collect personal data from minors in Mainland China. If you are located in Mainland China, you are strictly prohibited from creating accounts, using the Services, or making purchases. The Services are currently offered only to users outside Mainland China (including Hong Kong SAR, Macao SAR, Taiwan region, and other international jurisdictions).
• Users Outside Mainland China (International & Other Regions): For users located outside Mainland China (including Hong Kong SAR, Macao SAR, Taiwan region, and all other international jurisdictions), the Services comply with applicable global store content ratings (e.g., IARC 12+ / Teen ratings on the Apple App Store and Google Play). You must be at least 13 years old (or the higher statutory minimum digital age of consent in your country of residence, e.g., 14–16 in parts of the European Economic Area / UK) to use the Services. The Services are not directed to children under 13, and we do not knowingly collect personal data from children under 13.
• Minors and Parental Consent: If you are outside Mainland China and between 13 and the legal age of majority in your jurisdiction ("Minor"), you may only use the Services with the direct involvement, supervision, and prior express consent of your parent or legal guardian. By allowing a Minor to use the Services, the parent or guardian accepts these Terms on the Minor's behalf and assumes full joint and several legal responsibility for all activities of the Minor.
• In-App Purchases by Minors: All purchases of subscriptions (VIP) or virtual items made under your account are conclusively deemed authorized by the adult account holder or parent/guardian. Parents are strongly advised to enable operating system parental controls (e.g., Apple Screen Time / Ask to Buy, Google Play Family Link). Except where required by non-waivable consumer laws or app store mandatory refund rules, Eyedo disclaims any obligation to refund unauthorized purchases resulting from a guardian's failure to supervise device access.

2. Accounts, Security, and Ownership

• Platform Account Ownership: All accounts in the App are and remain the exclusive property of Eyedo. You are granted a limited, personal, non-exclusive, non-transferable, revocable license to access and use your account for personal, non-commercial entertainment.
• No Account Transfer or Sale: You may not sell, rent, lease, trade, gift, bequeath, or otherwise transfer your account or login credentials to any third party. Any private, unauthorized account transaction is strictly void and constitutes a material breach of these Terms, subjecting the involved accounts to immediate and permanent termination without refund.
• Credential Safeguarding: You are solely responsible for maintaining the confidentiality of your login credentials. You are legally responsible for all actions taken through your account.

3. Description of Services & VIP Subscriptions (EULA)

• The Services provide vector doodle creation, stroke-playback rendering, cloud canvas backup, and real-time social gameplay (such as Draw & Guess).
• VIP Memberships & Subscriptions: Premium subscriptions are offered via Apple App Store In-App Purchases or Google Play Billing. Subscriptions renew automatically unless cancelled at least 24 hours prior to the expiration of the current billing cycle. Pricing, renewal terms, and cancellation instructions are presented before purchase and governed by the VIP Service Agreement and the respective store's terms.
• Apple Standard EULA: For users who acquire the App from the Apple App Store, these Terms are also supplemented by and subject to the Apple Standard End User License Agreement (EULA).

4. User Content & Platform Distribution Rights

The Services allow you to create, upload, and interact with drawings, avatars, messages, and room chats (collectively, "User Content"). Regarding User Content and intellectual property rights:

• Ownership & Warranties: You retain whatever moral or intellectual property rights you hold in the original elements of User Content you create. You represent and warrant that your User Content is original or duly licensed, and does not infringe or violate any third-party intellectual property, privacy, or publicity rights.
• Comprehensive Worldwide License to Eyedo: To the maximum extent permitted by applicable law, you grant Eyedo an irrevocable, perpetual, worldwide, fully paid-up, royalty-free, transferable, and fully sublicensable (through multiple tiers) license to host, store, cache, reproduce, adapt, edit, modify, publish, publicly display, publicly perform, broadcast, syndicate, and distribute your User Content in connection with the Services and Eyedo's business.
• Cross-Platform Syndication & Third-Party Distribution:
  • Eyedo has the absolute right to syndicate, broadcast, publish, edit, clip, compile, and distribute your User Content, doodle playback videos, vector replay data, battle records, highlights, and game clips across any and all third-party media, video, and social networking platforms worldwide, including without limitation TikTok, YouTube, Instagram, X (Twitter), Facebook, Xiaohongshu, Bilibili, Douyin, Kuaishou, and WeChat Channels.
  • Platform Monetization Rights: You expressly acknowledge and agree that all revenues, advertising income, platform creator fund rewards, sponsorship earnings, or commercial profits generated from syndicating or distributing such content on any third-party channels belong exclusively and unconditionally to Eyedo. You irrevocably waive any right to any royalties, rev-share, compensation, or financial claims arising out of such syndication.
• Platform Native Assets & Replay Vectors: All underlying software code, canvas engines, brush algorithms, color palettes, game mechanics, user interface designs, audio assets, vector stroke structures, and algorithmic replay recordings are the sole and exclusive intellectual property of Eyedo.
• Sole Right of Enforcement: You irrevocably authorize Eyedo to act as your exclusive agent to investigate, issue takedown notices (including DMCA notices), and initiate legal proceedings against any third party that scrapes, misappropriates, or infringes upon User Content published on or derived from the Services, with all recovered damages and settlements retained solely by Eyedo.
• Personal Sharing Standards: If you personally share gameplay captures or doodles featuring Eyedo trademarks, logos, or gameplay on third-party platforms, you must clearly attribute the source to "Eyedo" and ensure the sharing is strictly personal, non-commercial, and non-disparaging.

5. Virtual Items & Digital Assets

All in-app items, balances, virtual coins, cosmetic skins, levels, and VIP benefits are licensed digital software service features — NOT personal property or chattel. They have zero real-world cash value, cannot be redeemed for fiat currency, and cannot be traded outside official game channels. All virtual items expire and terminate automatically upon service discontinuation or account closure without compensation.

6. Service Modification, Interruption, and Termination (Discontinuation Safe Harbor)

To the fullest extent permissible under applicable law:

• Right to Discontinue: Eyedo reserves the right, at its sole discretion, to modify, suspend, interrupt, or permanently terminate the Services (including shutting down game servers, removing features, or sunsetting the entire App) at any time for business restructuring, economic feasibility, technical upgrades, merger, bankruptcy, or regulatory requirements.
• Advance Notice Safe Harbor: Eyedo shall provide at least thirty (30) days' advance notice of permanent service discontinuation via an in-app notice or website announcement. The expiration of such 30-day notice period shall fully and conclusively discharge Eyedo from any and all ongoing performance obligations, and Eyedo shall be fully immunised and exempted from any continuing service liability.
• Forfeiture of Virtual Items and Unused VIP Periods: Upon the effective date of service termination, all unconsumed virtual items, virtual currencies, and remaining days of VIP subscription shall immediately lapse, expire, and be forfeited. Eyedo shall have no obligation to issue cash refunds, store credits, alternative digital currencies, or any compensatory payments whatsoever.
• No Data Retention or Export Duty: Users are solely responsible for downloading or exporting their drawings and data during the 30-day notice period. After termination, Eyedo reserves the right to permanently purge and delete all user accounts, creations, and logs from its servers, with no duty to preserve, retrieve, export, or restore any data.

7. Prohibited Conduct, Anti-Cheat, and Anti-Reverse-Engineering

You strictly agree not to:

• Decompile, disassemble, reverse engineer, decrypt, probe, or attempt to derive the source code or communication protocols of the Services;
• Create, distribute, promote, or use any bots, scripts, hacks, auto-guessers, speed hacks, modded APKs/clients, or automation tools;
• Exploit any bugs, unintended glitches, or system vulnerabilities for unfair gameplay advantage, item duplication, or commercial profit;
• Launch DDoS attacks, transmit malicious payloads, or overload server infrastructure.

Sanctions: Violation of this Section will result in immediate termination of access, confiscation of digital assets, device/hardware bans, and referral to civil or criminal law enforcement where appropriate, without any refund.

8. Community Safety, Zero Tolerance, and DMCA

• Zero Tolerance Policy for Objectionable Content & Abusive Behavior: Eyedo maintains a strict ZERO-TOLERANCE policy against objectionable, defamatory, offensive, hateful, obscene, violent, or harassing content, as well as abusive users. Any user who uploads, creates, or disseminates inappropriate content or engages in abusive behavior will have their content removed immediately, and their account will be subject to instant suspension, permanent termination, and device bans without prior notice or refund.
• Built-in Safety & Moderation Mechanisms:
  • Flagging / Reporting Content: Users can tap the Report button on any artwork, playback view, game room, or user profile to flag objectionable content. All flagged items are promptly reviewed and acted upon by our moderation team.
  • Blocking Abusive Users: Users can block abusive users at any time via the artwork menu, room member list, or user profile. Blocking instantly removes and conceals all content published by the blocked user from your feed and interactions, silences their communications, and automatically notifies the developer/moderators of the abusive user and inappropriate content for expedited investigation. You can manage your blocked users anytime in Settings > Blocked Users.
• DMCA / Copyright Takedown Notice: If you believe your copyrighted work has been copied in a way that constitutes infringement, please submit a written DMCA notice to our designated agent at support@eyedo.top including proof of ownership, identification of the infringing material, and your contact info. Valid notifications will be acted upon promptly.
• Indemnification: You agree to defend, indemnify, and hold harmless Eyedo, its officers, directors, employees, and agents from and against any and all claims, liabilities, damages, losses, fines, and expenses (including reasonable attorneys' fees and legal costs) arising out of or related to your User Content, your breach of these Terms, or your violation of applicable law.

9. Disclaimers and Limitation of Liability

• "AS IS" & "AS AVAILABLE": The Services are provided on an "as is" and "as available" basis without warranties of any kind, whether express, implied, or statutory. We disclaim all implied warranties of merchantability, fitness for a particular purpose, uptime, security, and non-infringement.
• Force Majeure: Eyedo is not liable for service delays or failures caused by acts of God, war, telecom breakdown, cloud provider outages, cyberattacks, government mandates, or labor strikes.
• Exclusion of Consequential Damages: To the maximum extent permitted by law, Eyedo shall not be liable for any indirect, incidental, special, consequential, punitive, or exemplary damages, including lost profits, loss of goodwill, data corruption, or device damage.
• Aggregate Liability Cap: In no event shall Eyedo's aggregate liability arising out of or relating to the Services exceed the greater of (a) the net amount you paid to Eyedo for the specific service in the thirty (30) days immediately preceding the event giving rise to liability, or (b) fifty United States Dollars ($50.00 USD).

10. Dispute Resolution: Binding Individual Arbitration & Class Action Waiver

• CLASS ACTION WAIVER: TO THE EXTENT PERMITTED BY LAW, YOU AND EYEDO AGREE THAT ALL DISPUTES MUST BE RESOLVED ON AN INDIVIDUAL BASIS. NEITHER YOU NOR EYEDO MAY BRING A CLAIM AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, CONSOLIDATED, OR REPRESENTATIVE PROCEEDING.
• Governing Law & Jurisdiction: These Terms shall be governed by and construed in accordance with the laws of the People's Republic of China, without regard to conflict of law principles. Any dispute that cannot be resolved amicably shall be submitted to the exclusive jurisdiction of the competent court in Pudong New Area, Shanghai, China — except where mandatory consumer protection laws of your country of habitual residence expressly preclude such forum selection.

11. General Provisions

If any provision of these Terms is deemed invalid or unenforceable, that provision will be enforced to the maximum extent permissible, and the remaining provisions shall remain in full force and effect. Eyedo's failure to enforce any right or provision shall not constitute a waiver. These Terms constitute the complete understanding between you and Eyedo regarding the Services.
