Amberia Terms of Service

Last updated: September 15, 2026 Effective date: September 15, 2026

These Terms of Service (the "Terms") are an agreement between you and Crazy Finger Studio Limited ("Amberia," "we," "us," or "our") governing your use of the Amberia Android and iOS applications and their related services (collectively, the "Service").

By using the Service, you agree to these Terms and acknowledge the Amberia Privacy Policy. If you do not agree, do not use the Service. Acceptance of these Terms does not itself grant tracking permission or replace any separate consent required by applicable law.

1. Operator and Contact

2. Eligibility

You must be at least 13 years old, or the higher minimum age required where you live, to use Amberia. If you have not reached the age of legal majority where you live, you may use the Service only with permission from a parent or legal guardian. The parent or guardian is responsible for reviewing purchases made by a minor through the applicable Apple or Google account.

You may not use the Service if applicable law prohibits you from receiving it.

3. Reader Accounts and Optional Sign-In

Amberia provides a guest reader account for your Library, reading progress, chapter access, Coin balance and purchase records. You do not need an email address or provider sign-in to start reading. Supported versions also offer third-party sign-in, such as Google, Apple or Facebook, using Firebase Authentication.

When you choose a provider, Amberia uses the authorized identity information to sign you in, create or access an account, and maintain account information. Successful sign-in can change the active reader account. Account linking, guest-data transfer and recovery depend on the supported operation and its confirmed result; provider authorization alone does not guarantee that accounts, Coins or purchases will be merged or transferred. You must control the provider account you use. The provider and Firebase apply their own terms and privacy policies.

Your account is identified by its reader ID and service credentials. On iOS, credentials may use iOS Keychain and synchronize through iCloud Keychain for the same Apple Account where enabled. On Android, credentials and account information use app-local storage and supported account recovery. Platform synchronization and cross-device recovery are not guaranteed.

You are responsible for the security of your device, provider accounts and device passcode. You may not sell, rent, transfer or share access to an Amberia account, or use another person's account without authorization. Contact support promptly if you suspect unauthorized access.

4. The Service

Amberia provides access to licensed serialized fiction and related reading features, including story discovery, search, Library management, reading history, chapter navigation, and access to free or paid chapters.

We grant you a personal, limited, revocable, non-exclusive, non-transferable license to use the Service for private, non-commercial reading, subject to these Terms and the applicable store terms, including the Apple Media Services Usage Rules for iOS. The app and its content are licensed, not sold.

Features, titles, chapters, release schedules, recommendations, availability, and prices may differ by country, device, storefront, or time. We may correct errors, maintain the Service, or change a feature where reasonably necessary. We will provide notice of material changes where required by law.

5. Stories and Content Access

Story text, covers, artwork, metadata, software, design, and other materials available through Amberia are owned by Amberia, its licensors, authors, publishers, or other rights holders. All rights not expressly granted are reserved.

Unlocking a chapter gives your Amberia account a limited right to access that chapter through the Service. It does not transfer ownership or permit reproduction, redistribution, public performance, resale, scraping, or commercial use.

We work to keep unlocked content available, but content may become unavailable because of law, licensing rights, rights-holder requests, safety requirements, technical limitations, or discontinuation of the Service. Nothing in this section limits remedies or mandatory rights available under applicable consumer law.

6. Coins and In-App Purchases

6.1 What Coins are

Coins are consumable digital items used only to unlock eligible paid chapters within Amberia. Coins:

Purchased Coins are not scheduled to expire while the account and Service remain available. This does not prevent adjustment of Coins obtained through fraud, duplicate delivery, a refunded or reversed transaction, or other error, to the extent permitted by law.

6.2 Buying Coins

Consumable Coin packs and subscriptions are different products. Subscription terms in Section 6.5 apply only where a subscription is actually offered in your app version and store region. Including those terms does not make a subscription available or enroll you in one.

On iOS, Coin purchases use Apple's in-app purchase system and StoreKit. On Android, Google Play purchases use Google Play Billing. The product, quantity and store-localized price are shown before authorization. The applicable store processes payment under the Apple or Google account used for the purchase and applies its tax and storefront rules. We do not receive your full payment-card details.

A StoreKit or Google Play purchase confirmation does not by itself mean Coins have been delivered. Amberia verifies the transaction and credits the Coin balance only after the service accepts the transaction. Transaction identifiers are used to prevent duplicate delivery. If delivery is delayed, Amberia may show the purchase as processing and automatically retry delivery.

6.3 Unlocking chapters

For a manual unlock, Amberia displays the chapter's Coin price and your available balance. When you choose to unlock and have enough Coins, the displayed amount is deducted and access is added to the account. If you enable automatic paid-chapter unlocking, intentionally continuing into an eligible paid chapter with sufficient Coins authorizes the applicable Coin charge without a separate confirmation screen for each chapter. You can disable it under Settings > Auto-unlock paid chapters. Charges are recorded in Coin activity.

A successful chapter unlock is recorded in your unlock history and Coin activity. Except where required by law or necessary to correct an error, Coin consumption for an accessed digital chapter is final.

6.4 Refunds and transaction issues

For Google Play purchases, refund eligibility follows Google Play policies and applicable law. Use Google Play refund support or contact Amberia support for purchase assistance. If Google Play refunds or reverses a transaction, we may adjust the related Coins or access to prevent duplicate or incorrect credit, to the extent permitted by law.

Refund eligibility and payment reversal for App Store purchases are determined by Apple and applicable law. You can request an eligible refund through Apple's reportaproblem.apple.com service or Apple Support. Amberia does not limit any mandatory consumer rights.

If Apple refunds or reverses a purchase, we may remove the corresponding undelivered Coins or adjust the account balance and related access to prevent an incorrect or duplicate credit, to the extent permitted by law. Contact [email protected] if Apple shows a completed charge but the Coins have not been delivered after processing finishes.

6.5 Membership subscriptions, where available

App Store subscriptions (iOS). The following Apple-specific payment, renewal and restoration terms apply to subscriptions billed by Apple. Google Play subscriptions are described separately below.

Availability and benefits. Amberia may offer optional auto-renewable membership subscriptions through Apple's in-app purchase system. Availability, included content and benefits, billing period, and any offer conditions are shown on the subscription purchase screen. No particular plan, launch date, free trial, or introductory offer is guaranteed by these Terms. Subscription access lasts only while the corresponding entitlement is valid; it is not a permanent purchase of the catalog. Chapters separately unlocked with Coins remain subject to Section 5 rather than becoming subscription-only purchases.

Price and payment. Review the plan's total billing price, currency and period before confirming. Prices are localized using information supplied by StoreKit for your App Store region; the Apple purchase confirmation shows the charge you authorize. A monthly equivalent, if shown for a longer plan, is not a separate monthly payment option. Apple bills the Apple Account used for the purchase. Future price changes are handled under Apple's notice and consent rules and applicable law.

Automatic renewal and offers. An auto-renewable subscription continues for successive billing periods unless canceled through Apple. Review the renewal date and price in your Apple subscription settings and cancel before renewal if you do not want another charge. If a free or discounted trial is offered, eligibility, duration and the subsequent regular price are disclosed before confirmation; it renews at the disclosed price unless canceled. Apple advises canceling a free or discounted trial at least 24 hours before it ends.

Managing and canceling. Use iOS Settings > your name > Subscriptions > Amberia, or open Apple subscription management. Cancellation stops future renewal and is not itself a refund request. Paid access normally continues until the expiration shown by Apple, subject to refunds, revocation, and applicable law; a trial may end earlier when canceled. Deleting the app, deleting your Amberia account, signing out, or removing Google/Apple sign-in authorization does not cancel an Apple subscription. See Apple's cancellation instructions.

Access and restoration. In versions offering subscriptions, use Restore purchases with the Apple Account used to subscribe if a valid subscription is not recognized, or contact support. Restoring a subscription does not repurchase it, recreate deleted Amberia account data, or restore consumable Coin packs as subscriptions. Access depends on verification of the entitlement and may change when a subscription expires, is refunded or revoked, or has an unresolved billing issue. Once membership expires, paid chapters not separately unlocked may require Coins. Contact support before deleting an account if you need help retaining access to a paid entitlement.

Refunds. Subscription refund requests follow Section 6.4 and Apple's refund process. Cancellation does not automatically refund a current billing period; eligibility depends on Apple and applicable consumer law. Nothing in these Terms limits mandatory refund or cancellation rights.

Google Play subscriptions (Android). Available benefits, billing period, total price, trial or introductory-offer conditions and renewal price are shown before confirmation. Google Play charges the Google account used to subscribe. Auto-renewing plans continue until canceled; cancel before the next renewal to avoid the next charge. A free or discounted offer renews at the disclosed regular price unless canceled. Price changes follow Google Play's notice and consent rules and applicable law.

Manage or cancel through Google Play → Payments & subscriptions → Subscriptions → Amberia or Google Play subscription management. See Google Play cancellation instructions. Cancellation generally stops future renewal while access continues for the remaining paid period, subject to the offer, refund and store terms. Cancellation is not a refund request; refunds follow Section 6.4. Deleting the app, deleting your reader account or signing out does not itself cancel the subscription.

If a Google Play subscription is not recognized, use the Google account that purchased it, reopen Amberia and contact support if access remains unavailable. Restoring a verified entitlement does not repurchase it, recreate deleted reader-account data or turn consumed Coins into a subscription. Access depends on verification and may change on expiration, refund, revocation or unresolved billing issues. Separately unlocked chapters remain subject to Section 5. A purchase through one store does not itself guarantee transfer to another store or account.

7. Acceptable Use

You agree not to:

  1. use the Service in violation of applicable law or the rights of another person;
  2. copy, record, reproduce, republish, distribute, sell, publicly display, or commercially exploit stories or other content except where expressly authorized;
  3. scrape, crawl, index, download in bulk, or use automated means to access the Service without written permission;
  4. bypass chapter locks, purchase verification, access controls, security controls, or usage limits;
  5. reverse engineer, decompile, disassemble, modify, or attempt to derive source code except to the extent such restriction is prohibited by applicable law or permitted by an applicable open-source license;
  6. interfere with the operation or security of the Service, introduce malicious code, overload systems, or probe for vulnerabilities without authorization;
  7. misuse feedback, support, notification, or purchase systems;
  8. impersonate another person or misrepresent your authorization; or
  9. use the Service or its content to infringe intellectual-property, privacy, publicity, or other rights.

We may investigate suspected misuse and may restrict or terminate access where reasonably necessary to protect users, rights holders, store transactions, or the Service. We will provide notice and an opportunity to appeal where required by law.

8. Feedback

If you submit product feedback or suggestions, you give us permission to use them to operate and improve Amberia without payment or restriction, provided that we do not publicly identify you without permission. Feedback does not transfer ownership of story content or other material that you do not own.

Do not send confidential information, passwords, payment-card details, or content you do not have the right to disclose.

9. Privacy, Advertising and Measurement

Our Privacy Policy describes guest accounts and supported third-party sign-in, profile information, purchases, and our use of Firebase Analytics, AppsFlyer and advertising/mediation services. Amberia displays third-party advertising in enabled placements. Analytics and attribution may include automatic and custom events, account identifiers, reading and purchase interactions, and advertising performance and revenue information.

Apple's App Tracking Transparency permission and IDFA apply to iOS. Android advertising identifiers and device advertising-privacy controls apply to Android. We request separate consent or permission where required. Refusing iOS tracking permission does not block core reading or purchasing, and does not stop every form of analytics, contextual advertising or attribution. Personalized recommendations are a separate choice and do not control all measurement or advertising. Accepting these Terms does not replace legally required consent.

10. Suspension and Termination

You may stop using Amberia at any time. We may suspend or terminate access if you materially violate these Terms, create a security or fraud risk, misuse purchases or Coins, infringe rights, or if we are legally required to do so.

Where reasonable and permitted, we will notify you and provide a chance to correct or appeal the issue before permanent termination. Immediate action may be taken where necessary to prevent harm, fraud, unauthorized access, or legal liability.

Termination does not affect rights or obligations that by their nature survive, including intellectual-property protections, valid payment obligations, dispute provisions, and legally required record retention.

11. Account Deletion

You can request deletion through Amberia account settings or the email route on our account deletion page. On Android, deletion takes effect after 30 days and can be canceled by signing in during that period. On iOS, follow the in-app confirmation. The consequences below apply when deletion is completed.

Account deletion is permanent. It ends access to the account and removes remaining Coins, unlocked-chapter access, Library state, reading progress, reading history, and other account data that we are not legally required to retain. Deleted accounts cannot be restored, and remaining Coins are not transferred to a new account.

Amberia may require an unfinished App Store or Google Play transaction to finish before deletion so that a paid transaction is not lost or incorrectly delivered to another account. Account deletion does not automatically request an App Store or Google Play refund. Refunds follow the applicable store process and law; contact support if an unfinished transaction prevents deletion.

If you have an Apple- or Google Play-billed Amberia subscription, deleting the account does not itself cancel automatic renewal. Manage or cancel through the billing store as described in Section 6.5. Restoring an eligible entitlement does not restore deleted account data.

We may retain limited transaction, security, fraud-prevention, tax, accounting, or legal records after deletion where required or permitted by law, as described in the Privacy Policy.

Deleting an Amberia account does not delete your Apple, Google or other provider account. We process deletion of associated personal data held by us and request deletion from service providers processing it on our behalf, subject to legitimate retention exceptions described in the Privacy Policy. Signing out, revoking provider authorization or uninstalling the app is not a request to delete the Amberia account.

12. Service Availability and Changes

The Service depends on networks, Apple and Google services, hosting infrastructure, and content licenses that may occasionally be unavailable. We may perform maintenance, correct errors, add or remove features, or discontinue some or all of the Service.

If we permanently discontinue a material paid feature or the Service, we will provide notice and any remedy required by applicable law. We will not use this section to exclude mandatory consumer rights.

13. Disclaimers

To the maximum extent permitted by applicable law, the Service is provided on an "as available" basis. We do not promise that every story, chapter, feature, or recommendation will always be available, uninterrupted, or error-free.

Nothing in these Terms excludes warranties, guarantees, or remedies that cannot lawfully be excluded. Some jurisdictions provide statutory consumer guarantees that continue to apply regardless of this section.

Fictional stories may contain mature, intense, romantic, supernatural, or otherwise sensitive themes. Story descriptions and available content labels are provided to help you make your own reading choices.

14. Limitation of Liability

To the maximum extent permitted by applicable law, Amberia and its officers, employees, affiliates, and service providers will not be liable for indirect, incidental, special, consequential, or punitive damages, or for loss of data, profits, or business opportunity arising from the Service.

To the maximum extent permitted by applicable law, our total aggregate liability arising out of or relating to the Service or these Terms will not exceed the greater of (a) the amount you paid through Amberia during the 12 months immediately before the event giving rise to the claim and (b) HKD 800.

Nothing in these Terms limits liability where limitation is prohibited, including liability for fraud, willful misconduct, death or personal injury caused by negligence where applicable, or mandatory consumer rights.

15. Platform-Specific Terms

15.1 Apple / iOS

On iOS, your download and use of Amberia are also subject to the applicable Apple Media Services Terms and Usage Rules. Unless a custom end-user license agreement is supplied through the App Store, Apple's Standard Licensed Application End User License Agreement applies to the licensed application.

These Terms are between you and Crazy Finger Studio Limited, not Apple. To the extent required for a custom end-user license agreement, Apple and its subsidiaries are third-party beneficiaries of the applicable Apple-specific provisions and may enforce them after your acceptance. Apple is not responsible for operating the Amberia Service, providing Amberia support, or addressing claims relating to Amberia except as required by Apple's own terms or applicable law.

15.2 Google Play / Android

For downloads and purchases through Google Play, the applicable Google Play terms and billing rules also apply. These Terms are between you and Crazy Finger Studio Limited. Apple-specific terms, including Apple's EULA and third-party-beneficiary provisions, do not apply to the Android application merely because they appear in this combined document.

16. Changes to These Terms

We may update these Terms to reflect changes in the Service, law, or business practices. We will update the date at the top and provide additional notice where required. Changes will not apply retroactively where prohibited by law.

If you do not agree to updated Terms, you must stop using the Service and may delete the account. Continued use after the effective date of updated Terms constitutes acceptance only to the extent permitted by applicable law.

17. Governing Law and Disputes

These Terms and any dispute arising out of or relating to them or the Service are governed by the laws of the Hong Kong Special Administrative Region, without regard to conflict-of-law principles.

The courts of Hong Kong have non-exclusive jurisdiction. If you are a consumer, this choice does not deprive you of mandatory protections or the right to bring a claim in another court available under the laws of your usual place of residence. Nothing in these Terms requires arbitration or waives a right that cannot lawfully be waived.

Before starting formal proceedings, you and Amberia agree to try in good faith to resolve the dispute by contacting [email protected], unless this requirement is prohibited by applicable law or urgent relief is necessary.

18. General Terms

If a provision of these Terms is found unenforceable, it will be enforced to the maximum lawful extent and the remaining provisions will remain effective. Failure to enforce a provision is not a waiver. You may not assign these Terms without our consent; we may assign them as part of a merger, acquisition, reorganization, or transfer of the Service, subject to applicable law.

These Terms, the Privacy Policy, and any purchase terms presented at the time of transaction form the agreement between you and Amberia concerning the Service, without limiting applicable terms imposed by Apple or Google Play or rights under applicable law.
