Terms of Service (End User License Agreement)

Version: 1.0 | Effective date: 13 October 2026

Welcome to “Civo Color” (listed in app stores as “Civo Color: Color by Number”, the “App” or the “Service”), operated by Nanjing Heyback Technology Co., Ltd. (the “Company”, “we”, “us”). These Terms also serve as the App’s End User License Agreement (EULA) and include the subscription terms (Section 6) and additional terms for users who obtain the App from the Apple App Store (Section 11). By installing or using the Service, you agree to be bound by these Terms. If you do not agree, please uninstall the App.

Age guidance: The App is intended for users aged 13 and over (its Google Play target audience is 13+). If you are under 13, please do not use the App. If local law requires parental consent for minors, please use the Service with your parent’s or guardian’s consent and supervision.

1. Definitions

  1. “User” / “you” means any individual who downloads, installs or uses the Service. The App does not offer account registration; paid entitlements are tied to your Apple ID or Google Play account.
  2. “Content” means all materials provided through the Service, including line-art pictures, coloring templates, palettes, interface, text and graphics.
  3. “Artwork” means an image you create by coloring a line-art picture in the App.
  4. “Civo Pro” or the “Paid Service” means the premium features unlocked by an auto-renewing subscription, as described in Section 6.
  5. “Applicable Laws” means the laws in force in your jurisdiction, the Company’s jurisdiction and the governing law of these Terms.

2. The Service

  1. The App provides color-by-number features: built-in line-art pictures that you color area by area according to the numbers. Some pictures are free; others are unlocked with Civo Pro or by watching a rewarded video ad, as shown in the App.
  2. Your coloring progress and Artwork are stored only on your device. We do not upload them to our servers and do not provide cloud backup. Uninstalling the App, clearing its data or changing devices will cause your coloring progress to be lost, and it cannot be recovered. You can save finished Artwork to your photo library to keep it.
  3. If you do not subscribe to Civo Pro, the App shows ads (see Section 7).
  4. We may update, add, change or remove pictures and features from time to time and do not guarantee that any picture or feature will remain available permanently.

3. Access & Device Identifiers

  1. No account is required. The App creates an anonymous user ID through Google Firebase and a device ID on your device, which are used for analytics, subscription syncing, feedback and push notifications as described in the Privacy Policy.
  2. Civo Pro entitlements are bound to your Apple ID / Google Play account. After reinstalling the App or changing devices, use “Restore Purchases” in the App to recover your entitlements; restoring purchases restores the subscription only, not local coloring progress.
  3. You are responsible for maintaining the security of your device and store account credentials. All actions taken on your device are deemed to be yours.

4. License & Rules of Use

  1. Subject to these Terms, we grant you a limited, revocable, non-exclusive, non-transferable and non-sublicensable licence to install and use the App on devices that you own or control, solely for personal, non-commercial purposes. If you obtained the App from the Apple App Store, you may use it only on Apple-branded products that you own or control and as permitted by the Usage Rules in the App Store Terms of Service.
  2. You must not:
    • reverse engineer, decompile or disassemble the App, or attempt to derive its source code (except as expressly permitted by applicable law);
    • rent, lend, sell, sublicense, distribute or otherwise transfer the App or this licence;
    • circumvent, crack or tamper with the App’s payment, advertising or other technical protection measures;
    • scrape, export or copy Content (including line-art pictures) by automated or bulk means;
    • remove or alter any copyright, trademark or other proprietary notices in the App or its Content;
    • interfere with the normal operation of the Service or attempt to gain unauthorised access to related systems;
    • use the App for any unlawful or infringing purpose.
  3. All rights not expressly granted in these Terms are reserved by the Company or its licensors.

5. Intellectual Property & Artwork

  1. The App (including code, interface, line-art pictures and coloring templates, trademarks and logos) is owned by the Company or its licensors and is protected by copyright laws and international treaties. These Terms do not transfer any ownership to you.
  2. Your Artwork is based on our line-art pictures. We permit you to keep your Artwork on your devices, use it for personal, non-commercial purposes and share it through personal channels such as social media (please do not remove any App branding the Artwork may contain when sharing).
  3. Without our prior written permission, you may not use line-art pictures or Artwork for commercial purposes, including selling them, selling prints, making and selling merchandise, redistributing them as assets, or using them to train artificial-intelligence models.
  4. Any rights you have by law in your own color choices are not affected, but they do not extend to the line-art pictures themselves.
  5. If you believe any Content in the App infringes your rights, email support@xiaoheigohome.com with proof of ownership, the location of the material, your contact details and a statement that your notice is accurate. We will handle valid notices in accordance with the law.

6. Subscriptions & Payments (Civo Pro)

* Prices above are for the United States. Prices in other countries/regions are set by Apple / Google in local currency including applicable taxes; the price shown at checkout prevails.

6.2 Payment & Activation

  1. All payments are made through the Apple App Store or Google Play. We never collect your payment details directly.
  2. When you confirm a purchase, payment is charged to your Apple ID / Google Play account, and your entitlements take effect immediately after the charge succeeds.
  3. Entitlements are available on devices signed in with the same Apple ID / Google Play account through “Restore Purchases”. Apple Family Sharing and Google Play Family Library are not supported.

6.3 Auto-Renewal & Cancellation

  1. Subscriptions renew automatically unless auto-renewal is turned off at least 24 hours before the end of the current period. Your account will be charged for renewal within the 24 hours before the end of the current period.
  2. How to cancel:
    • iOS: Settings › tap your Apple ID at the top › Subscriptions › Civo Color › Cancel Subscription;
    • Android: Google Play Store › profile icon › Payments & subscriptions › Subscriptions › Civo Color › Cancel subscription.
  3. Uninstalling the App does not cancel your subscription.
  4. After cancellation, your benefits remain available until the end of the current paid period. Fees already charged are not refundable, unless applicable law provides otherwise or the platform approves a refund.
  5. If a renewal payment fails, Apple / Google may provide a grace period during which your benefits continue. If the platform still cannot collect payment, your benefits end and the App reverts to the free version.

6.4 Free Trial

  1. The free trial applies only to Civo Pro Yearly; Monthly and Weekly subscriptions do not include a trial.
  2. Trial eligibility is determined by Apple / Google: each Apple ID / Google Play account can usually redeem a trial only once, and accounts that have already redeemed a trial in the App or previously subscribed to Civo Pro may not be eligible. The checkout screen shows whether a trial applies.
  3. To avoid being charged, cancel at least 24 hours before the trial ends; otherwise the Yearly price is charged automatically when the trial ends.
  4. If you purchase another subscription plan during the trial, any unused portion of the trial is forfeited.

6.5 Price Changes

We may change prices because of exchange rates, taxes or operating costs. New prices apply only to subsequent billing periods. Apple / Google will notify you in advance under their rules and ask for your consent where their rules require it; if you do not agree with a new price, turn off auto-renewal before it takes effect.

6.6 Refunds

Refunds must be requested through Apple’s or Google’s official channels; see the Refund & Cancellation Policy (https://static.xiaoheigohome.com/civo/legal/refund-policy/index.html). Once a refund is granted, the corresponding subscription ends immediately and Civo Pro benefits stop. This section does not affect your other statutory rights (for example, the statutory right of withdrawal of EU consumers).

6.7 Fair Use

  1. Civo Pro is for personal use only. Reselling it, or renting out devices or accounts that carry a subscription, is prohibited.
  2. We may suspend or terminate entitlements that are abused or used unlawfully.
  3. If we permanently discontinue the App before your paid subscription period ends, we will help you obtain a proportional refund through the platform or provide equivalent compensation.

7. Advertising

  1. If you do not subscribe to Civo Pro, the App shows app-open ads and rewarded video ads. Rewarded videos are watched only if you choose to, and on completion you receive the reward described in the App. Rewards have no cash value and cannot be transferred or redeemed.
  2. Whether ads are personalised depends on your consent and device settings; see Sections 2.6 and 8 of the Privacy Policy.
  3. Ads are provided by third-party ad networks. We make no warranty about advertisers’ products or services.

8. Privacy

Our processing of personal information is governed by the Privacy Policy at https://static.xiaoheigohome.com/civo/legal/privacy-policy/index.html. If these Terms conflict with the Privacy Policy regarding the processing of personal information, the Privacy Policy prevails.

9. Disclaimer of Warranties

  1. The Service is provided “AS IS” and “AS AVAILABLE”. To the maximum extent permitted by law, we disclaim all express or implied warranties, including warranties of merchantability, fitness for a particular purpose and non-infringement, and we do not guarantee that the Service will be continuously available, error-free or uninterrupted.
  2. Because coloring progress is stored only on your device, we are not liable for progress lost due to uninstalling the App, clearing its data, or changing or losing your device.
  3. This section does not affect rights you have under mandatory consumer protection laws in your jurisdiction that cannot be excluded by agreement.

10. Limitation of Liability

  1. To the maximum extent permitted by law, we are not liable for any indirect, incidental, special, punitive or consequential damages arising from your use of or inability to use the Service.
  2. Our aggregate liability to any User shall not exceed the total fees that User paid for the Service in the twelve (12) months preceding the claim.
  3. Liability that cannot be excluded or limited by law (for example, for personal injury caused by intent or gross negligence) is not limited by this section.

11. Additional Terms for Apps Obtained from the Apple App Store

If you downloaded the App from the Apple App Store, the following terms also apply. If they conflict with any other part of these Terms, this section prevails:

  1. Acknowledgement: These Terms are concluded between you and the Company only, and not with Apple Inc. (“Apple”). The Company, not Apple, is solely responsible for the App and its content.
  2. Scope of licence: Your licence is limited to a non-transferable licence to use the App on any Apple-branded products that you own or control and as permitted by the Usage Rules set forth in the App Store Terms of Service, except that the App may be accessed and used by other accounts associated with the purchaser via Family Sharing or volume purchasing.
  3. Maintenance and support: The Company is solely responsible for providing any maintenance and support services as specified in these Terms or as required under applicable law. You acknowledge that Apple has no obligation whatsoever to furnish any maintenance and support services with respect to the App.
  4. Warranty: The Company is solely responsible for any product warranties, whether express or implied by law, to the extent not effectively disclaimed. In the event of any failure of the App to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price (if any) for the App to you. To the maximum extent permitted by applicable law, Apple will have no other warranty obligation whatsoever with respect to the App, and any other claims, losses, liabilities, damages, costs or expenses attributable to any failure to conform to any warranty will be the Company’s sole responsibility.
  5. Product claims: The Company, not Apple, is responsible for addressing any claims by you or any third party relating to the App or your possession and/or use of the App, including but not limited to: (i) product liability claims; (ii) any claim that the App fails to conform to any applicable legal or regulatory requirement; and (iii) claims arising under consumer protection, privacy or similar legislation.
  6. Intellectual property rights: In the event of any third-party claim that the App or your possession and use of the App infringes that third party’s intellectual property rights, the Company, not Apple, will be solely responsible for the investigation, defence, settlement and discharge of any such claim.
  7. Legal compliance: You represent and warrant that (i) you are not located in a country that is subject to a U.S. Government embargo, or that has been designated by the U.S. Government as a “terrorist supporting” country; and (ii) you are not listed on any U.S. Government list of prohibited or restricted parties.
  8. Developer name and address: Please direct any questions, complaints or claims regarding the App to the Company at the name, address and email listed in Section 17.
  9. Third-party terms: You must comply with applicable third-party terms of agreement when using the App (for example, your wireless data service agreement).
  10. Third-party beneficiary: Apple and Apple’s subsidiaries are third-party beneficiaries of these Terms, and upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary.

12. Service Changes & Termination

  1. We may modify, suspend or terminate the Service or any part of it at any time for business, legal or technical reasons.
  2. For material changes that significantly reduce paid benefits, we will give at least 30 days’ notice in the App and explain how to cancel or obtain a refund.
  3. You may stop using the Service at any time by uninstalling the App. Because we do not maintain user accounts, uninstalling the App terminates this licence. Uninstalling does not cancel your subscription; please cancel as described in Section 6.3.
  4. We may suspend or terminate this licence if you breach these Terms or Applicable Laws. Upon termination, you must stop using and delete the App. Sections 5, 9, 10, 11 and 13 survive termination.

13. Governing Law & Dispute Resolution

  1. These Terms are governed by the laws of the People’s Republic of China (excluding conflict-of-law rules).
  2. Disputes shall first be resolved by friendly negotiation within 30 days after they arise.
  3. If negotiation fails, the dispute shall be submitted to the Jiangsu Sub-Commission of the China International Economic and Trade Arbitration Commission (CIETAC Jiangsu Sub-Commission) for arbitration in Nanjing under its rules in force. The arbitration will be conducted in Chinese, and the award shall be final and binding.
  4. Both parties waive the right to bring claims through class or representative actions. If this waiver is held unenforceable, the arbitration clause ceases to apply and disputes will be brought before the competent court at the defendant’s domicile.
  5. Either party may seek interim or injunctive relief from a competent court to protect intellectual property or confidential information.
  6. If you are a consumer, this section does not deprive you of the protection of mandatory laws of your country of habitual residence, including, where applicable law allows, the right to bring proceedings before your local courts.

14. Third-Party Services

The App integrates third-party services from Apple, Google (Firebase, AdMob, Google Play), RevenueCat and others, which are governed by their own terms and privacy policies. Purchases made through the Apple App Store or Google Play are also subject to the respective platform’s terms. We are not responsible for third-party websites, services or content.

15. Force Majeure

We are not liable for delays or failures caused by events beyond our reasonable control, including natural disasters, government actions, internet disruptions, power outages or war, but we will make reasonable efforts to reduce their impact.

16. Changes to These Terms

If we update these Terms because of legal or feature changes, we will update the version number and effective date at the top; for material changes we will notify you in the App. Continued use of the Service after the effective date constitutes acceptance of the updated Terms.
