Last updated: 2026-06-28 Nature of this version: These Common Terms of Use are the master agreement to which you individually agree within the App.

> These Common Terms of Use (the "Terms") are the master agreement between you and the operator of the Service in respect of the Lueurly service. The Privacy Policy, Acceptable Use Guidelines, Data Retention Policy, Account Deletion Notice, Children and 18+ Statement, Subscription and Refund Disclosure, and DMCA Copyright Policy (the "Individual Policies") are incorporated into and form part of these Terms.

1. Definitions

"The operator of the Service," "we," or "us" means TZU-YU CHIU, an individual developer based in Taiwan, operating as Lueurly (not a registered trademark or company), being the operator of and the contracting counterparty for the Lueurly service. Contact: [email protected].

"Lueurly," "the Service," or "the App" means the Lueurly iOS App, the backend services, the website legal center, the messaging functions, the Keepsake archive functions, the subscription functions, and related services.

"Content" means the text, voice, photos, Keepsake archives, signatures, wax seals, replies, chat threads, metadata, and other materials provided through the Service. "User Submitted Content" means content that you create, upload, send, receive, sign, report, or otherwise submit through the Service.

"Service Fee" means the charge for paid features. "Subscription" means the auto-renewing Premium subscription offered through Apple StoreKit. "Individual Service Terms" means terms separately established for a specific feature and presented to you.

"Product feature names": certain features are referred to by both a product name and a functional description, both of which refer to the same feature: "Fading Light" means burn-after-read (a best-effort feature that, after reading, clears the message content from the server's active storage on a timer); "Light Up Together" means Sync Open (a shared time-window open feature that does not use location); "Keepsake" means the pact (a personal commitment and record feature, including optional witness friends, that can be exported as a PDF); "Trusted device binding" means device-bound; "Scheduled send" means scheduled delivery; "Anonymous message" means anonymous.

2. Use of and Consent to the Service (18+)

To use the Service, whether or not a service fee applies and whether or not account registration is required, you must agree to these Terms. When you tap to agree within the App, create an account, access the Service, purchase a subscription, send messages, sign a Keepsake, or otherwise use the Service, you accept these Terms.

You must be at least 18 years of age. Lueurly is for adults only, is rated for an adult audience, and is not designed, marketed, or offered for children or minors. Lueurly uses a neutral age screen and requires you to declare that you are at least 18 years old; by using the Service you represent and warrant that this declaration is true. The neutral age screen is only a screening mechanism and is not a guarantee of identity or age verification. If we learn of or have actual knowledge that an account belongs to a person under 18 (or that we have collected personal information of a child under 13), we may, to the extent permitted or required by applicable law and as appropriate, suspend, disable, terminate, delete, or anonymize that account and the related data.

3. Account Registration Information

When registering an account, you are obligated to provide true, accurate, and non-misleading information and to proactively correct it to keep it current. The account is personal to you and, except as permitted by the Service, may not be assigned, sold, leased, lent, or otherwise granted to a third party. If your account is deleted or terminated, your right to use the Service ends.

Without the prior written consent of the operator of the Service, you may not assign, transfer, or delegate your rights or obligations under these Terms. The operator of the Service may assign or transfer these Terms in connection with a service reorganization, legal succession, asset transfer, or change in operations, without diminishing your rights under mandatory law.

4. Provision of the Subscription Service

Lueurly Premium is offered through Apple StoreKit as a monthly auto-renewing subscription. The actual price, taxes, and currency are as displayed in the App Store at the time of purchase. Unless you cancel at least 24 hours before the end of the current period, the subscription will automatically renew. Apple processes payment and refunds; the operator of the Service does not receive your card number and does not separately process App Store refunds.

Premium features are provided only during the period in which both Apple and the Lueurly entitlement system show a valid entitlement. Subscription expiration, charge failure, refund, revocation, end of a grace period, or account deletion or termination may cause Premium features to be disabled immediately. Features that rely on Premium (including Scheduled send, Fading Light, Light Up Together, Trusted device binding, Anonymous message, and the creation or export and audit settings of Keepsake) may re-verify the entitlement at operationally relevant times, such as creation, use, renewal, processing, or scheduled delivery; if the entitlement has lapsed at that point, then except where prohibited by law or App Store rules, the operator of the Service may cancel, downgrade, disable, delete, or refuse to deliver the relevant features, messages, settings, or records.

5. No Emergency Reporting Function

Lueurly is not an emergency, rescue, medical, law enforcement, or alert service. Do not use Lueurly to request emergency assistance or to send time-sensitive safety communications; contact your local emergency services directly.

6. Content and Minimum Necessary License

You retain ownership of your User Submitted Content, without affecting the rights of others. You grant the operator of the Service a limited, non-exclusive, worldwide license, solely to the extent reasonably necessary, to host, store, transmit, display, process, and technically reproduce your User Submitted Content, in order to operate, protect, review, support, and improve the Service and to comply with the law. You represent that you have the rights necessary to submit it and that the content does not violate these Terms, the Acceptable Use Guidelines, or applicable law.

7. Handling of User Data and Content

Due to limitations of the technical architecture and security controls, the operator of the Service does not, under ordinary circumstances, proactively review User Submitted Content; however, where reasonably necessary to handle reports, abuse investigations, legal compliance, security incidents, enforcement of these Terms, or operation or protection of the Service, it may process the relevant data in accordance with these Terms and the Privacy Policy.

8. Review and Deletion of Messages

Messages are generally available only to the sender, the recipient, and the system processes necessary to deliver the Service. Certain metadata (for example, delivery, read, device, Light Up Together activation, Keepsake audit, report, or screenshot-detection records) may be processed for the relevant features.

9. Account and Password Responsibility

You are responsible for maintaining the confidentiality of your account credentials and trusted devices. Except as caused by the willful misconduct or negligence of the operator of the Service, you are responsible for activity carried out through your account. If you suspect unauthorized access, you should notify us as soon as possible at [email protected].

10. Provision, Suspension, and Termination of the Service

You are responsible for your device, operating system, network connection, telecommunications charges, and a compatible software environment. The operator of the Service may suspend, restrict, or interrupt all or part of the Service where reasonably necessary for maintenance, security, abuse prevention, legal compliance, infrastructure failure, force majeure, or other operational reasons. For planned material interruptions, reasonable notice will be provided to the extent practicable.

If you violate these Terms or the Acceptable Use Guidelines, create legal or security risk, abuse Anonymous message, infringe rights, circumvent review, use a minor's account, or harm the Service or other users, the operator of the Service may suspend, restrict, or terminate your account or access. For ordinary violations, an attempt will be made to notify you to the extent practicable; for serious abuse, fraud, security threats, child sexual abuse material, imminent harm, legal risk, or repeated violations, action may be taken without prior notice. You may delete your account within the App via Settings -> Delete Account; if you cannot use the App, you may contact [email protected]. Deletion is handled in accordance with the Account Deletion Notice and the Data Retention Policy.

11. Service Provided As Is, No Warranty, and Nature of Features

The Service is provided on an "as is" and "as available" basis. To the maximum extent permitted by law, the operator of the Service makes no warranty of merchantability, fitness for a particular purpose, title, non-infringement, uninterrupted operation, error-free operation, availability, accuracy, or data retention. Consumer rights that may not be waived under the law are unaffected.

Feature names such as "Fading Light" (burn-after-read), "Light Up Together" (Sync Open), "Trusted device binding" (device-bound), and "Anonymous message" are merely descriptive shorthand for the convenience of the features and are not a promise of confidentiality, security, encryption, irreversibility, deletion, anonymity, or any particular outcome. Fading Light is a convenience feature and is not a guarantee of information security, encryption, or confidentiality, and it cannot prevent a recipient or others from retaining, screenshotting, recording, or copying content. Do not use the Service to send information you need to keep confidential. Burn-after-read content is cleared from the server's active storage within at most 1 hour after the applicable read and expiry conditions are met; for a multi-recipient message, content may be retained until all relevant recipients meet the system clearance conditions. The operator of the Service does not promise immediate, irreversible, forensic-level, or recipient-device-side deletion.

12. Prohibited Conduct

The operator of the Service has a zero-tolerance policy toward objectionable content and abusive conduct, including any sexual exploitation, online enticement, or child sex trafficking of minors. You may not use Lueurly to: violate the law or the rights of others; harass, threaten, stalk, extort, impersonate, dox, or abuse any person; send hateful, extremist, sexually exploitative, non-consensual intimate, violent, gory, or other offensive content; create, request, possess, distribute, or promote child sexual abuse material; spam, phish, defraud, manipulate, or deceive; upload malware, exploit vulnerabilities, bypass security controls, scrape, or overload the Service; reverse engineer the Service (except where applicable law confers a non-waivable right); use Anonymous message to evade responsibility; share accounts, resell access, or use the Service for unauthorized commercial messaging; or interfere with the reporting, review, subscription, payment, or security systems.

Anonymous message may hide the sender from the recipient, but anonymity does not mean immunity. The operator of the Service will retain identifying information for safety, abuse-prevention review, legal compliance, and appropriate law enforcement requests.

13. Contact Matching and Friend Discovery

Contact matching is an optional feature that you actively enable. If enabled, the operator of the Service may read the email addresses in your device's contacts, normalize them locally and generate SHA-256 hashes, and upload only those hashes to the server for matching; contact names, phone numbers, addresses, notes, or plaintext email addresses are not uploaded. You must ensure that you have lawful authorization. You may withdraw consent or delete synced hashes at any time, except that existing friend relationships, invitations, blocks, and abuse or security records may be retained in accordance with the applicable features or retention rules.

14. Intellectual Property and Restrictions on Use of the Service

The operator of the Service and its licensors reserve all rights in the App, software, interfaces, designs, service names, trademarks, documentation, backend systems, and other non-user materials. The operator of the Service grants you a limited, personal, non-transferable, non-sublicensable, and revocable permission to use the Service for your personal, lawful purposes. Except as expressly permitted by these Terms or mandatory law, you may not copy, modify, distribute, sell, lease, sublicense, or host the Service or create derivative works. Copyright complaints are handled in accordance with the DMCA Copyright Policy. Before the DMCA Copyright Policy takes effect (that is, before the designated agent is registered and the policy is published), copyright complaints are handled under the general notice procedure via [email protected].

15. Light Up Together Safety and Offline Interaction

Lueurly is a digital messaging service. Light Up Together (Sync Open) is a time-window feature: when participants each choose to "light up" within a shared time window, the message opens. This feature does not use, collect, or require your location, and does not require you to be in any particular place or near any other person. Some users may choose to use Light Up Together when they happen to be physically together, but that is entirely their own voluntary choice, which the operator of the Service neither directs nor requires as a precondition. Because such features may involve interacting with others in the real world, you should confirm the safety of your location and surroundings before acting. If you choose to meet or interact with other users offline, you do so entirely at your own risk and assume that risk. The operator of the Service does not arrange, facilitate, supervise, or guarantee any in-person meeting and is not responsible for offline conduct, meetings, or their consequences. In an emergency, contact your local law enforcement or emergency services immediately. This clause does not limit any liability that may not be excluded under the law.

16. Keepsake and Electronic Signing

The signing records and audit metadata provided by the operator of the Service (which may include time, device information, IP address, user agent, and, when enabled and available, GPS) serve only as supporting evidence of an expression of intent. The operator of the Service does not provide legal advice; the operator of the Service is not a law firm, notary, witnessing service, or contract drafting service, and does not verify the identity of signatories. The Keepsake feature is a personal record-keeping and audit-metadata tool and is not a qualified, certified, or witnessed electronic signature service, and it does not guarantee compliance with eIDAS QES, ESIGN, UETA, or any electronic signature law. Whether a pact has legal effect, evidentiary capacity, or enforceability depends on applicable law, the facts, the true intent of the parties, and the determination of a competent authority or court. For any agreement that you intend to be legally binding, consult a qualified attorney and use an appropriate method of signing; never rely on a Keepsake as a legal contract or proof of identity.

17. User Indemnification of the Operator of the Service

To the extent permitted by law, if, as a result of your willful or negligent breach of these Terms, your User Submitted Content, your misuse of the Service, your violation of the law, or your infringement of the rights of others, a third party brings a claim against the operator of the Service or the operator of the Service incurs loss, damage, liability, cost, or reasonable expense, you agree to indemnify and hold the operator of the Service harmless; except as to the portion caused by the operator of the Service's own unlawful conduct, willful misconduct, or gross negligence. This indemnification obligation does not apply to the extent prohibited by mandatory consumer protection law.

18. Disclaimer

18.1. Except as caused by the willful misconduct or gross negligence of the operator of the Service, the operator of the Service bears no liability arising under any circumstances.

18.2. Notwithstanding the foregoing, if the contract between you and the operator of the Service concerning the use of the Service under these Terms constitutes a consumer contract as defined by the Consumer Protection Act of the Republic of China (Taiwan), then, except as caused by the willful misconduct or gross negligence of the operator of the Service, the operator of the Service shall be liable to compensate only for loss or damage within the ordinary scope, with the amount of compensation capped at the Service Fee for the paid service (equivalent to one month's fee in the case of a subscription service), and excluding lost profits and other damages arising from special circumstances.

18.3. If loss is caused to you by the gross negligence of the operator of the Service, the operator of the Service does not compensate for lost profits or other damages arising from special circumstances, and is liable only for loss or damage within the ordinary scope, with the amount of compensation capped at the Service Fee for the paid service (equivalent to one month's fee in the case of a subscription service); provided, however, that if the contract between you and the operator of the Service concerning the use of the Service under these Terms constitutes a consumer contract as defined by the Consumer Protection Act of the Republic of China (Taiwan), the foregoing arrangement does not apply.

18.4. These Terms do not exclude or limit liability for personal injury, fraud, willful misconduct or gross negligence, or any liability that may not be excluded or limited under the law.

19. Dispute Resolution, Binding Arbitration, and Class Action Waiver

Please read this clause carefully. This clause affects your legal rights. Except as provided below and as otherwise required by mandatory law, for **users residing in the United States**, most disputes must be resolved by individual arbitration with a waiver of class actions.

19.1. Informal negotiation first: Before commencing any arbitration or proceeding, you and the operator of the Service agree to first attempt to resolve the dispute informally for at least sixty (60) days (by writing to [email protected]).

19.2. Individual arbitration (U.S. users): If you reside in the United States, any dispute arising out of these Terms or the Service, except for the exceptions in Section 19.5 and where you have validly opted out under Section 19.4, shall be resolved by binding individual arbitration conducted by the American Arbitration Association (AAA) under its Consumer Arbitration Rules, governed by the U.S. Federal Arbitration Act (FAA, 9 U.S.C. §§1 et seq.).

19.3. Class action and jury waiver (U.S. users): Arbitration is conducted on an individual basis only; both you and the operator of the Service waive the right to bring or participate as a class, collective, representative, or private attorney general, and waive a jury trial. If the class action waiver is found unenforceable as to a particular claim, that claim shall be severed to court while the rest proceeds in arbitration.

19.4. Thirty-day right to opt out: Within 30 days after first accepting these Terms, you may opt out of Sections 19.2–19.3 by email ([email protected]) stating your account email and your intent to opt out of arbitration. Those who opt out are subject to Section 26.

19.5. Exceptions: Claims within the scope of small claims court, seeking an injunction or equitable relief for intellectual property rights or unauthorized use, and the operator of the Service's collection of subscription fees, are not subject to arbitration.

20. Apple App Store Additional Terms

When you obtain the App through the Apple App Store, the following additional terms apply and, in the event of any inconsistency with the other terms, prevail: These Terms are solely between you and the operator of the Service, and not with Apple Inc. ("Apple"); Apple is not responsible for the App or its content and has no maintenance or support obligation. To the maximum extent permitted by law, Apple provides no warranty; if the App fails to conform to a warranty, you may notify Apple, and Apple may refund the purchase price (if any). Apple is not responsible for addressing any claim by you or a third party relating to the App (including product liability, non-compliance with law, and consumer protection claims). If a third party alleges that the App infringes its intellectual property rights, then to the extent required by law, the operator of the Service (and not Apple) is responsible for addressing it. You represent that you are not located in a country that is subject to a U.S. embargo or designated as supporting terrorism, and that you are not on any U.S. list of prohibited or restricted parties. Apple and its subsidiaries are third-party beneficiaries of these Terms and may enforce these Terms against you in that capacity.

21. Third-Party Services

The operator of the Service relies on third-party services (including infrastructure service providers such as Apple, Google, Firebase Cloud Messaging, Hetzner Online GmbH, Resend, and Cloudflare). Those service providers are subject to their own terms and privacy practices. The operator of the Service is not responsible for third-party services beyond its control, but will select processors in accordance with the Privacy Policy to operate the Service.

22. Notices

The operator of the Service may send notices through the App, email, the website, push notifications, or other reasonable means. Contact and dispute point of contact: [email protected].

23. Privacy

The Privacy Policy explains how the operator of the Service collects, uses, stores, discloses, and retains personal data. Before using the Service, you should read and understand the Privacy Policy. For processing activities that require consent under the law, the operator of the Service will obtain the necessary consent in accordance with applicable law.

24. Priority of Individual Service Terms and Individual Policies

If there is any difference between these Terms and the Individual Service Terms, then, unless otherwise agreed, the Individual Service Terms prevail for that specific feature. These Terms and the Individual Policies (Privacy Policy, Acceptable Use Guidelines, Data Retention Policy, Account Deletion Notice, Children Statement, Subscription Disclosure, DMCA Policy) constitute the entire agreement between you and the operator of the Service. Each Individual Policy prevails within the scope of its respective subject matter (such as privacy, retention periods, community standards, refunds, copyright handling); only where the general provisions of these Terms and an Individual Policy conflict and the matter falls outside the aforementioned subject matter do these Terms control, in order to avoid inconsistency.

25. Changes to the Terms

The operator of the Service may update these Terms due to changes in the Service, the law, security needs, subscription, or operational practices. Material changes will be reasonably notified before they take effect through the App, the website, email, or other appropriate means. If applicable law or App Store rules require express consent for a material change, the operator of the Service will request that consent before the updated terms apply to you. If you continue to use the Service after a reasonable notice period, you are deemed, to the extent permitted by law, to have accepted the updated terms.

26. Governing Law and Jurisdiction

The interpretation and application of these Terms are governed by the laws of the Republic of China (Taiwan). For any dispute arising out of or relating to these Terms or the Service, except for the arbitration agreement applicable to U.S. users under Section 19, the Taiwan Taipei District Court shall be the court of first instance; provided, however, that this does not apply where applicable mandatory law confers on a consumer the right to sue or be sued in the courts of the consumer's place of residence. This jurisdiction agreement does not deprive a consumer of the mandatory protections enjoyed under the laws of the consumer's place of residence. The arbitrability of the arbitration agreement for U.S. users is governed by the FAA.

27. Official Version and Language

These Terms have the **Traditional Chinese version as the official version**. The making, validity, and interpretation of these Terms are governed by the Traditional Chinese version. The English version and other language versions are translations provided for convenience only; in the event of any discrepancy among the versions, the Traditional Chinese version prevails. However, the foregoing choice of language does not diminish the non-waivable rights enjoyed by a consumer under the mandatory law of the consumer's place of residence; where mandatory law entitles a consumer to invoke its language version, that version prevails for that consumer to the extent of the conflict. In addition, with respect to the arbitration agreement for users residing in the United States under Section 19, the English version may prevail to the extent necessary for interpretation and enforcement under the U.S. Federal Arbitration Act (FAA), in order to maintain the enforceability of that arbitration agreement.

(This "Official Version and Language" clause is the only clause among all of Lueurly's legal documents that declares an official version; the other documents do not separately declare an official language version. However, a document produced solely in English to comply with a specific foreign law—such as the DMCA Copyright Policy produced in English for U.S. DMCA compliance—has its English text as the applicable version, and the foregoing Traditional-Chinese-official rule does not require such an English-only document to also have a Traditional Chinese version.)

28. Limitations on the Application of These Terms

Lueurly does not target residents of the European Union, the European Economic Area, the United Kingdom, Switzerland, or South Korea, and is not offered or marketed to those regions. The Service is not directed to residents of those excluded regions; if the mandatory law of those regions nonetheless applies, the operator of the Service will comply with the non-waivable rights it confers. These Terms do not exclude any user rights that may not be excluded under the law.

29. Severability

If any provision of these Terms is held invalid, unlawful, or unenforceable in any jurisdiction, that provision will be severed or reduced to the minimum required by law in that jurisdiction, and the remaining provisions will remain in full force and effect. The survival and severability of Section 19 (Arbitration) are governed by that section.
