1. Agreement to Terms

These Terms of Service ("Terms") constitute a legally binding agreement between you ("User", "you", or "your") and Lumera GlobalTech Limited, a company incorporated under the laws of Hong Kong Special Administrative Region ("Lumera", "we", "us", or "our"). By accessing or using our website at lumeraglobal.co, mobile application, or any letter subscription services (collectively, the "Services"), you confirm that: (a) you are at least 18 years of age; (b) you have the legal capacity to enter into binding contracts; (c) you have read, understood, and agree to be bound by these Terms and our Privacy Policy; and (d) if you are using the Services on behalf of an organization, you have authority to bind that organization to these Terms. IF YOU DO NOT AGREE TO THESE TERMS, YOU MUST NOT ACCESS OR USE THE SERVICES.

2. Service Description

  • Lumera provides an electronic letter subscription service that curates and dispatches letters on your behalf to designated recipients through supported delivery channels. Our service tiers are as follows:
  • Free Member: Weekly letter delivery to one designated recipient.
  • Lumera Plus: Daily letter delivery (USD $30 per month). Billed monthly on a recurring basis.
  • Premium Trial: Daily letter delivery, available exclusively by partner invitation. Terms of the trial are specified in the relevant invitation.
  • Lumera reserves the right to modify, suspend, or discontinue any service tier at any time with reasonable notice. We do not guarantee that a particular letter will be accepted or delivered, as processing is subject to the applicable receiving party's rules and procedures.

3. Eligibility and Account Registration

  • You must be at least 18 years of age to use the Services. By using the Services, you represent and warrant that you meet this requirement.
  • You agree to provide accurate, current, and complete information during registration and to update such information to keep it accurate, current, and complete.
  • You are solely responsible for maintaining the confidentiality of your account credentials and for all activities that occur under your account. You must notify us immediately at support@lumeraglobal.net of any unauthorized use of your account.
  • We reserve the right to refuse registration, suspend, or terminate any account at our sole discretion, including where we reasonably believe that information provided is inaccurate, fraudulent, or in violation of these Terms.

4. Subscription, Payment, and Billing

  • Subscription Fees: Lumera Plus is priced at USD $30 per month, billed on a recurring monthly basis until cancelled.
  • Annual Plan: Lumera Plus Annual, offered in the iPhone app through the App Store, is priced at USD $289 per year, billed once a year until cancelled.
  • Recurring Billing: By subscribing to Lumera Plus, you authorize Lumera to charge your designated payment method on a recurring monthly basis at the then-current subscription rate until you cancel. Subscription fees are charged at the beginning of each billing cycle.
  • Payment Processing: Purchases made in the iOS application are processed by Apple through Apple In-App Purchase. Apple handles iOS subscription billing, cancellation, and refund requests under Apple’s applicable terms. The current Android version does not offer in-app purchases or Google Play Billing. Purchases made on the Lumera website are processed through Antom. By providing payment information through a platform or website that offers a purchase, you represent that you are authorized to use the designated payment method.
  • Taxes: All subscription fees are exclusive of applicable taxes, levies, duties, or similar governmental assessments. You are solely responsible for paying all such taxes.
  • Price Changes: We reserve the right to change subscription pricing at any time. We will provide at least 30 days advance notice of any price increase. Your continued use of the Services after the effective date of a price change constitutes your acceptance of the new price.
  • Failed Payments: If a payment fails, we may suspend your access to paid features until payment is successfully processed. We are not liable for any loss or damage resulting from service suspension due to payment failure.

5. Cancellation and Refund Policy

  • For subscriptions purchased in the iOS application, you may manage or cancel renewal through your Apple Account subscription settings. The current Android version does not offer Android in-app subscriptions. For subscriptions purchased through the Lumera website, you may cancel through your account settings at lumeraglobal.co/portal/account or by contacting support@lumeraglobal.net. There are no cancellation fees.
  • Upon cancellation, you will retain access to Lumera Plus features until the end of the current paid billing period. No partial refunds are provided for unused portions of a billing period.
  • ALL SUBSCRIPTION FEES ARE NON-REFUNDABLE EXCEPT AS EXPRESSLY SET FORTH HEREIN OR AS REQUIRED BY APPLICABLE LAW. We do not provide refunds for periods already billed.
  • If you believe you have been charged in error, contact support@lumeraglobal.net within 30 days. For purchases made through Apple or Google Play, refund requests are handled under their applicable policies. For purchases made through Antom on the Lumera website, we will investigate and, if an error is confirmed, issue a credit or refund at our discretion where permitted by applicable law.

6. License Grant and Restrictions

  • Subject to your compliance with these Terms, Lumera grants you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to access and use the Services solely for your personal, non-commercial purposes.
  • You may not: (a) sublicense, sell, resell, transfer, assign, or otherwise exploit the Services for any commercial purpose; (b) copy, modify, adapt, translate, or create derivative works based on the Services; (c) reverse engineer, disassemble, decompile, or otherwise attempt to derive the source code of the Services; (d) use the Services in any manner that could damage, disable, overburden, or impair our servers or networks; (e) use automated tools, bots, or scripts to access or interact with the Services without our prior written consent; or (f) remove, alter, or obscure any proprietary notices on the Services.

7. Letter Content, Delivery, and Content Prohibition

  • Lumera's professional team curates letter content designed to be positive, encouraging, and appropriate for the intended delivery process. Content is selected based on your stated preferences and recipient needs.
  • CONTENT PROHIBITION: Lumera strictly prohibits any letter content — whether originating from Lumera's team, submitted or requested by subscribers, or derived from any third-party source — that violates or may violate: (a) any applicable law or regulation; (b) the rules, policies, or guidelines of the relevant delivery channel or receiving party; or (c) Lumera's internal content standards. Lumera reserves the absolute and unilateral right to review, modify, withhold, or permanently block any letter content at any time, without prior notice and without any obligation to provide reasons. No refund or credit will be issued where a letter is withheld due to content prohibition.
  • RECEIVING PARTY AS FINAL ARBITER: Lumera's role is strictly limited to preparing and transmitting letters electronically. All letters are subject to the sole and absolute discretion of the receiving party, including its screening procedures, content review policies, and acceptance or rejection decisions. The receiving party is the final and exclusive arbiter of whether a letter is accepted, printed, forwarded, or delivered. Lumera has no control over, and expressly disclaims all responsibility for, any decision made by a receiving party regarding delivery. LUMERA IS NOT LIABLE FOR ANY LETTER THAT IS REJECTED, WITHHELD, DELAYED, LOST, OR NOT DELIVERED FOR ANY REASON WHATSOEVER, INCLUDING BUT NOT LIMITED TO POLICY CHANGES, PROCESSING INTERRUPTIONS, RECIPIENT STATUS CHANGES, ADMINISTRATIVE DECISIONS, OR ANY OTHER CIRCUMSTANCE BEYOND LUMERA'S CONTROL. NO REFUND OR CREDIT WILL BE ISSUED ON THE BASIS OF NON-DELIVERY WHERE LUMERA HAS SUCCESSFULLY TRANSMITTED THE LETTER THROUGH THE APPLICABLE DELIVERY CHANNEL.
  • You acknowledge that receiving parties may inspect, copy, retain, or destroy communications at their discretion pursuant to their policies and applicable law, and that Lumera has no influence over such actions.

8. Prohibited Activities

  • You agree not to use the Services to:
  • Provide false, misleading, or fraudulent recipient information or delivery details.
  • Request, submit, or encourage content that violates a delivery channel's or receiving party's policies, rules, or security procedures.
