ScanLingo: Learn by Reading Service and Subscription Terms

1. Agreement structure and acceptance

These terms govern the relationship between you and the operator, 戚蕴杰, for use, subscriptions, and support of ScanLingo: Learn by Reading.

These are supplemental developer use and subscription terms. They are not a custom end-user license agreement that replaces the Apple Standard EULA.

By downloading, installing, accessing, or using the app, you accept these terms to the maximum extent permitted by applicable law. If you do not accept them, do not use the app.

Apple's Licensed Application End User License Agreement (Apple Standard EULA) also applies. These supplemental terms do not replace provisions that must apply under that agreement or Apple platform rules.

2. Eligibility

You must have legal capacity under applicable law to agree to these terms and make an App Store purchase.

A minor must use the app with a guardian's understanding and any consent required by applicable law. Guardians should manage device permissions and purchases.

The app is not in the Kids Category and is not provided specifically for children.

3. Limited license

Subject to these terms and the Apple Standard EULA, the operator grants you a revocable, non-exclusive, non-transferable personal license to use the app only on devices allowed by Apple's rules.

• Do not rent, lease, resell, distribute, or sublicense the app except where Apple's rules expressly permit arrangements such as Family Sharing
• Do not reverse engineer, defeat security, or bypass entitlement controls except to the limited extent applicable law does not permit that restriction
• Do not remove rights notices, interfere with services, or use the app for unlawful activity

The operator and relevant licensors reserve all rights not expressly granted.

4. Features and service scope

The app may provide camera or image OCR, translation, speech recognition, text to speech, book-and-page association, sentence cards, learning profiles, and reports. Features depend on the device, iOS version, language packs, and regional availability.

We may update, adjust, or discontinue features for improvement, security, compliance, or technical compatibility. Any material effect on a paid entitlement will be handled under applicable law and Apple's rules.

The app is a language and learning aid. It does not provide legal, medical, financial, safety, or other professional advice and is not a certified translation service.

Object vocabulary uses the bundled OpenMMLab RTMDet-s FP16 Core ML model on the device to generate general-object candidates from an image you choose or take; you may review, edit, and save vocabulary. The model is not downloaded at runtime, and the current release does not send source images to the operator's servers. The bundled model file is approximately 20.2 MB.

5. Acceptable use

• Process only material that you have the right to capture, import, copy, translate, or use
• Do not use the app to infringe privacy, intellectual property, personality, or other rights
• Do not introduce malicious code, interfere with network services, bypass subscription verification, or impersonate another person's entitlement
• Do not use the app for unlawful surveillance, fraud, abuse, or other illegal activity

If there is a reasonable basis to believe use is unlawful, threatens security, or infringes another person's rights, we may restrict related network functions or take necessary action to the maximum extent permitted by applicable law and Apple's rules.

Do not use Object vocabulary for identity recognition or verification, biometric processing, surveillance, law enforcement, medical, transport, safety control, emergency response, authenticity or model-number determination, or any decision that may materially affect a person, property, or rights.

6. Your scanned and learning content

You do not transfer to the operator any rights you hold in images, audio, text, edits to translations, or study notes merely by using the app.

You grant only the limited processing permission needed to provide the on-device feature or support that you request. The current release does not require a license to local learning content for advertising or model training.

You are responsible for checking machine output, protecting and backing up the device, and deciding whether content is suitable for your purpose.

You must have the necessary rights or permission for material that you scan, import, record, copy, translate, or share, and must comply with confidentiality, privacy, and intellectual-property duties.

7. Local data, backup, and loss risk

Images, OCR text, translations, book-and-page associations, sentence cards, learning profiles, and reports are stored on your device by default. You are responsible for device-access security and any export or backup you need.

Removing the app, clearing data, deleting items, device failure or loss, or a system restore may make local content unrecoverable. Restore Purchases restores only a verifiable subscription entitlement, not local learning content.

Before removing the app, replacing a device, or performing a major system operation, preserve any content you need using an available method.

The RTMDet-s FP16 model is delivered with the app resources. A normal app update may replace the model version, while Clear local learning data does not remove the model resource; deleting the app removes the app and its resources through iOS.

8. Subscriptions, auto-renewal, and Apple billing

Subscriptions are offered only through Apple App Store in-app purchase. Before confirmation, Apple's purchase sheet identifies the product, price, currency, period, and any offer or trial.

If the purchase sheet identifies an auto-renewable subscription, it renews for the period confirmed by Apple unless you cancel before Apple's stated renewal cutoff.

The exact price, currency, billing period, trial, and renewal terms are those shown on the in-app purchase page and Apple's confirmation sheet when you buy.

Apple charges your Apple Account and handles tax, payment methods, Family Sharing, and billing. The operator does not directly receive complete payment-card details.

Use Restore Purchases in the app to restore entitlements verifiable from transactions for the current Apple Account. The result depends on valid status returned by Apple and entitlement services.

Cancel through iOS or another subscription setting provided by Apple. Removing the app, deleting local data, or stopping use does not automatically cancel a subscription.

Apple decides refund requests under its process and rules applicable in your country or region. These terms do not restrict statutory refund or consumer rights. Mandatory consumer rights to refunds, withdrawal, digital-content delivery, and consumer protection are not limited by these terms. Apple controls App Store cancellation and refund workflows, without removing any additional rights available under the law where you live. Apple handles cancellation and refund requests under the rules of the purchaser's App Store storefront. These terms preserve any mandatory consumer remedy in an included storefront.

Subscription entitlement and local content are separate. Canceling does not automatically delete local data, and deleting local data does not cancel an Apple subscription. Free, subscribed, and other tiers may all view the complete history of weekly reports; there is no limit on the number of weeks available, and tier differences do not restrict weekly-report history. The Free tier may use up to 20 shared word cards, phrase cards, and sentence cards in total; the entitlement shown in the App controls.

9. App intellectual property

The app's software, interactions, original text, visual assets, and ScanLingo: Learn by Reading brand are protected by intellectual-property law and belong to the operator or relevant licensors.

Apart from the limited license to use the app, these terms do not transfer ownership or intellectual-property rights in the app or any component.

Apple and other third-party names, marks, and content remain the property of their respective owners.

OpenMMLab RTMDet-s, MMDetection, and the converted artifact are subject to their Apache 2.0 license, attribution, and third-party notices. Settings' Third-party notices provide applicable source, version, attribution, and license information; these terms grant no rights to extract, redistribute, or otherwise use the component beyond its applicable license.

10. Feedback

If you voluntarily provide a product suggestion that is not subject to a confidentiality duty, you allow us to use, improve, and implement it without payment to you. This does not affect your rights in other content.

Do not include unnecessary personal information, scanned material, or another person's confidential information in product feedback.

11. Third-party platforms and services

The app relies on Apple systems and the App Store, RevenueCat subscription-entitlement infrastructure, the Tally feedback form that you choose to open, the static Cloudflare Pages site, and email services.

When using a third-party platform or service, you are also subject to its terms, privacy policy, account rules, and regional requirements. The App uses bundled legal documents and does not fetch legal-document metadata from a remote database at runtime. Website and App documents are released with the same version. Cloudflare hosts the static legal and support site and delivers language packs from R2 when you choose to download them. It may process ordinary network metadata such as IP address, request time, user agent, requested object path, and security events; it does not receive the learning content stored in the App.

External links are provided for convenience. To the maximum extent permitted by applicable law, the operator does not control or accept responsibility for a third party's independent content, decisions, or availability.

Object vocabulary depends on Apple Core ML and other platform technologies together with the bundled OpenMMLab RTMDet-s model. Apple's independent system services are governed by Apple's own rules; the operator does not control Apple's independent processing or system availability.

12. Availability, updates, and interruption

Features may change with iOS, devices, language packs, third-party APIs, law, or the product. We cannot promise that every historical feature will remain permanently available.

We may suspend necessary network functions for security, fraud prevention, maintenance, legal compliance, or prevention of infringement. Where circumstances allow, we will try to limit the impact.

Maintenance, network conditions, upstream services, or force majeure may cause temporary interruption. Availability of local functions still depends on the device and system.

The model is bundled and does not require a network download; however, model loading, compilation, or recognition may fail, be delayed, or be unavailable because of device resources, system version, image quality, or software errors, and no continued availability of every category or historical result is promised.

Your limited licence terminates if you materially breach these terms and do not cure the breach within any notice or cure period required by applicable law. We may restrict only the affected network function when reasonably necessary for security, fraud prevention, legal compliance, or protection of rights. Termination does not cancel an Apple subscription automatically, erase local data automatically, or remove any statutory remedy or paid entitlement that must remain available under applicable law or Apple's rules.

13. Disclaimers and output limitations

To the maximum extent permitted by applicable law, the app is provided as is and as available. We do not promise uninterrupted or error-free operation, a particular result, or complete compatibility where such promises cannot reasonably be made.

OCR, speech recognition, translation, read-aloud output, and learning reports are automated and may omit information, contain errors, or be unsuitable for context. Check the original and do not use an output as the sole basis for a high-risk decision.

We cannot guarantee recovery of unbacked-up local content after app removal, device loss or failure, data clearing, or another local deletion event.

This section does not exclude any express or implied warranty, contractual duty, or consumer right that cannot lawfully be excluded.

Object-recognition output is probabilistic candidate information and may be incomplete or incorrect. Review and edit it before saving; do not use candidates, confidence values, or translations as the sole basis for identity, brand, model, price, safety, or other high-risk decisions.

Translations, text recognition, object candidates, speech recognition, pronunciation, and other learning-assistance results are generated by machine models, dictionaries, or system services for study reference only. They may be incomplete, inaccurate, or unsuitable for the context. Check the context yourself; do not use them as the sole basis for medical, legal, financial, safety, or other important decisions. The service does not use personal information to make legal or similarly significant automated decisions and does not build advertising or credit profiles. Recognition, translation, speech, and object-candidate outputs are learning aids that you can review and edit.

14. Limitation of liability

To the maximum extent permitted by applicable law, the operator is not liable for indirect, incidental, special, or consequential losses that were not reasonably foreseeable, or for losses caused by your failure to check automated output, back up local data, or comply with these terms.

Any liability extends only to loss that is direct and reasonably foreseeable from the operator's breach of an applicable duty, taking account of each party's responsibility and duty to mitigate.

Nothing in these terms limits liability for intentional misconduct or gross negligence, personal injury, fraud, or any other liability that cannot lawfully be limited, and nothing reduces mandatory consumer remedies.

To the maximum extent permitted by law, the operator is not responsible for decisions, actions, or inaction based on object-recognition candidates, confidence values, translations, or model availability, except for liability that law does not permit the operator to limit.

To the maximum extent permitted by applicable law, the operator's total aggregate liability arising from or relating to the App or these terms will not exceed the greater of the amount you paid for the App during the 12 months before the event giving rise to the claim or USD 100 (or its local-currency equivalent). This cap does not apply to fraud, intentional misconduct, gross negligence, personal injury, or any liability or mandatory consumer remedy that cannot lawfully be limited.

15. Loss caused by prohibited use

If your intentional or negligent unlawful use, infringement of third-party rights, or breach of these terms directly causes reasonable and evidenced loss, you are responsible for that loss.

We will give reasonable notice of a related claim and allow you to participate where doing so does not prejudice the defense. We will not accept a settlement imposing a non-monetary obligation on you without your consent.

This section applies only to the maximum extent permitted by applicable law. It does not transfer to you loss caused by the operator's own intent, negligence, or statutory responsibility, and does not exclude mandatory consumer rights.

16. Governing law and disputes

To the maximum extent permitted by applicable law, and subject to any mandatory consumer protection under the law of your place of residence, these terms and disputes relating to the app are governed by the laws of the People's Republic of China.

Please first describe the dispute and requested resolution at [email protected]. The parties may try to resolve it through good-faith discussion within a reasonable period.

If discussion does not resolve the matter, either party may bring proceedings before a people's court with jurisdiction under PRC law. If mandatory consumer law permits you to pursue a claim elsewhere, this clause does not restrict that right.

This clause does not require you to waive any non-waivable regulatory complaint, consumer mediation, collective, or judicial remedy. Mandatory protections for consumers, data subjects, and minors override any conflicting governing-law, venue, or liability-limit language in these terms. Mandatory consumer and privacy protections in an included storefront prevail over conflicting wording. This release is not offered in the EU, EEA, or United Kingdom.

17. Apple Standard EULA and the App Store

These site terms supplement app features, subscriptions, and developer support. They do not claim to be or replace a custom EULA, and they do not displace the Apple Standard EULA.

The Apple Standard EULA applies at the same time. If these supplemental terms conflict with a mandatory provision of that EULA, the Standard EULA controls the Apple-platform licence matter.

Apple is not the developer or content operator under these supplemental terms. The developer, not Apple, is responsible for the app itself and developer support; Apple handles its App Store, billing, and refund processes.

To the extent required by the Apple Standard EULA and applicable Apple rules, Apple and its subsidiaries are third-party beneficiaries of terms concerning the app license and may enforce those terms as those rules provide.

You must also comply with applicable Apple Media Services Terms and Conditions, App Store usage rules, sanctions and export-control requirements, and other third-party agreements that apply when you use the app.

18. General terms

These supplemental terms, the Privacy Policy, subscription conditions shown when you purchase, and the Apple Standard EULA that applies at the same time together form the agreement documents for their respective subjects.

If a term is held invalid or unenforceable, its purpose will be preserved to the greatest extent permitted by law, and the remaining terms continue in effect.

A delay in exercising a right is not a waiver. A waiver for one event is not a waiver for a later or different breach.

You may not assign the license or billing rights under these terms without consent, without affecting device or Family Sharing allowed by Apple. If the operator transfers relevant obligations as part of a business succession, the operator will comply with applicable law and protect your mandatory rights.

Each published language version is provided directly for its readers and is intended to be substantively equivalent. If a translation difference arises, the version required by applicable mandatory law governs; no language clause removes a mandatory consumer or data-protection right.

We may update these terms for changes to features, providers, security, law, or Apple requirements. Material changes will receive reasonable advance notice through the App or legal site where practicable or legally required, will identify a new effective date, and will request renewed acceptance when required. Continued use after that date constitutes acceptance only to the extent permitted by law; if you disagree, stop using the App and manage any subscription through Apple. An update does not retroactively remove mandatory rights or alter an already-paid entitlement contrary to applicable law.

Provisions concerning intellectual property, user responsibility, local-data risk, accrued payment obligations, disclaimers, liability, disputes, and any term that by its nature should continue remain effective after the licence or your use ends, to the extent permitted by law.
