DigiBound Terms of Use
These terms govern your use of DigiBound and its supporting services provided by Guangzhou Yixin Yiyi Information Technology Co., Ltd. (“we”, “us”, or “our”).
Contents
1. Eligibility and acceptance
You must be legally capable of entering into these terms. If local law requires a parent or guardian’s authorization, that person must review and accept these terms for you. You may not use the service where doing so is prohibited by law.
2. Service and limited license
Subject to these terms and the applicable App Store rules, we grant you a personal, limited, non-exclusive, non-transferable, non-sublicensable, revocable license to install and use the app on Apple-branded devices you own or control, solely for its intended purpose.
The features, content, subscription benefits, supported regions, and technical requirements may be described in the app or App Store listing. Rights not expressly granted remain reserved.
3. Anonymous installation identity
The service may create a random installation identifier and a long-lived bearer credential stored by the app in the device Keychain. This is not a personal profile or traditional account, but it protects service access and helps restore verified subscription rights after reinstalling the app.
- Do not intentionally copy, disclose, forge, reverse engineer, or misuse installation credentials or attestation material.
- Loss of Keychain data, device security changes, or unsupported platform behavior may require a new installation identity.
- We may reject or rebind an identity when integrity checks fail or when necessary to prevent fraud and protect the service.
4. Subscriptions and in-app purchases
- Purchases are offered and billed by Apple through the App Store. The purchase screen must show the subscription name, duration, benefits, full renewal price, and any trial or introductory terms before confirmation.
- Auto-renewable subscriptions renew according to the period and billing rules shown by Apple unless canceled in your Apple Account subscription settings before renewal.
- Payment authorization, taxes, refunds, billing disputes, and cancellation mechanics are governed by Apple’s applicable terms and policies. We cannot directly charge your payment method or cancel an Apple subscription for you.
- The app may verify Apple-signed transaction information to grant, restore, expire, revoke, or correct access. Access can change after refunds, revocations, billing failures, expiration, fraud checks, or updated information from Apple.
- Restoring purchases requires the same eligible Apple purchase history and successful server verification. Cross-device availability may depend on product configuration, Apple rules, network access, and integrity checks.
You can manage subscriptions at Apple’s subscription settings.
5. Acceptable use
You agree not to:
- break the law, infringe rights, harass others, or use the service for harmful or deceptive activity;
- bypass subscriptions, access controls, rate limits, App Attest, DeviceCheck, or other security mechanisms;
- submit forged transactions, replay assertions, automate abusive requests, probe vulnerabilities without authorization, or disrupt the service;
- copy, modify, distribute, sell, lease, decompile, or reverse engineer the app except where applicable law expressly permits it;
- use the service to build a competing dataset or product in violation of these terms.
6. Ownership and feedback
The app, service, software, design, text, trademarks, and other materials are owned by us or our licensors and are protected by applicable intellectual-property laws. If you provide feedback, you grant us permission to use it without restriction or compensation, unless prohibited by law.
7. Updates and availability
We may maintain, update, add, limit, or discontinue features to improve the service, address security or legal requirements, or reflect third-party platform changes. The service may be interrupted by maintenance, network conditions, Apple services, outages, or events beyond our control. We do not promise that every feature will always be available in every region or on every device.
8. Suspension and termination
You may stop using the service at any time; uninstalling the app does not cancel an App Store subscription. We may suspend or terminate access when reasonably necessary to address a material breach, fraud, security risk, legal requirement, or threat to other users or the service. Provisions that by their nature should survive termination remain in effect.
9. Disclaimers and limitation of liability
To the maximum extent permitted by law, the service is provided “as is” and “as available.” We disclaim implied warranties of merchantability, fitness for a particular purpose, non-infringement, and uninterrupted or error-free operation.
To the maximum extent permitted by law, we are not liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for loss of data, profits, goodwill, or access arising from the service. Any aggregate liability will be limited to the greater of the amount you paid for the service during the preceding twelve months or the minimum amount required by applicable law.
Nothing in these terms excludes rights or liability that cannot legally be excluded, including mandatory consumer protections.
10. Apple-specific terms
These terms are between you and the app provider, not Apple. Apple is not responsible for the app or its content, maintenance, support, warranties, claims, or legal compliance except as required by Apple’s own terms. Apple and its subsidiaries are intended third-party beneficiaries of the license terms applicable to the app and may enforce them where permitted.
11. Applicable law, changes, and contact
These terms are governed by the laws of the People’s Republic of China. Subject to mandatory consumer protections and other non-waivable rights in your place of residence, disputes shall be submitted to a court with jurisdiction in Guangzhou, China.
We may update these terms to reflect service, security, platform, or legal changes. Revised terms will be posted at this URL with a new effective date. If a material change requires consent, we will request it as required by law.
