Welcome to LuveDay. These Terms of Service ("Terms") govern your access to and use of the LuveDay application (the "App") provided by Young Dai Zi Innovation ("we," "our," or "us").
By downloading, accessing, or using LuveDay, you agree to the terms set forth in this agreement and our Privacy Policy.
LuveDay is a personal chat-style journaling and sharing platform featuring End-to-End Encryption (E2EE). The App allows users to securely store and sync encrypted personal messages, calendar anniversary events, upload images and files, track monthly spending, and personalize their digital experience.
The monthly spending tracker and financial management tools provided within LuveDay are for personal reference and informational purposes only. We do not provide professional financial, tax, or legal advice. You understand and agree that you bear full responsibility for the data entered and any financial decisions made based on such data. Young Dai Zi Innovation shall not be liable for any real-world financial losses resulting from system delays, calculation errors, or data loss.
You must be 16 years old and above to use this App. By creating an account, you represent and warrant that you meet this age requirement and have the legal capacity to enter into a binding agreement.
By creating an account, you agree to:
Critical Security & Key Management Notice: LuveDay operates on a Zero-Knowledge architecture. Your account's cryptographic private key is encrypted locally on your device using a key derived from your user password before being stored in our database. In addition, you are issued 5 offline recovery keys that remain solely in your possession.
Because your raw password and offline recovery keys are never transmitted to or stored on our servers, we possess no technical capability to decrypt your private keys or recover your encrypted data if you lose your credentials. You explicitly acknowledge and agree that the loss of both your account password and offline recovery keys results in the permanent, unrecoverable loss of your encrypted content (messages, files, calendar events, and financial entries).
You retain full ownership of the messages, images, files, and calendar items ("User Content") you upload. Because your content is End-to-End Encrypted, it is transmitted and stored on our servers as unreadable data payloads. By using the App, you grant us a non-exclusive license to host, store, transfer, and sync these encrypted payloads solely for the purpose of operating the App and delivering services to your connected devices.
LuveDay is designed as a private, closed digital space between two connected users and does not host public forums or community feeds. You agree NOT to upload, store, or share content that:
Enforcement Limitations in Zero-Knowledge E2EE: Because your User Content is fully End-to-End Encrypted, our servers cannot read, scan, or automatically moderate your private messages, files, or calendar entries. If a dispute or acceptable use violation occurs, users may manually contact customer support at contact@youngdaizi.com. We reserve the right to suspend or terminate accounts, destroy access tokens, and revoke service access for any user found violating these terms.
You acknowledge and accept specific limitations regarding data storage within the App:
Encrypted text messages, metadata, and financial tracking data are stored on our servers until you manually delete them or delete your account.
Storage Policy: Encrypted images and files uploaded to the App are securely stored on our servers to enable cross-device syncing and accessibility. While we strive to maintain high availability for your data, we reserve the right to implement storage management protocols as necessary to maintain service performance.
Unlike transient messaging data, uploaded media files remain associated with your account and will not be automatically deleted by us. However, you are solely responsible for managing your storage usage. You may manually delete any files or images at any time, which will permanently remove them from our servers. We encourage you to maintain your own local backups of critical media files, as we are not liable for any data loss resulting from device failure, account deletion, or unforeseen technical disruptions.
To optimize server performance and properly allocate infrastructure resources, we reserve the right to suspend or permanently delete accounts under the Free Tier that have been inactive with no login operations for a continuous period of 12 months. Upon deletion, all locally cached and cloud-synced encrypted backup data associated with the account will be permanently removed. Where applicable, we will make reasonable efforts to notify you via in-app notifications or your registered email address prior to taking such action.
In addition to content restrictions, you agree NOT to:
LuveDay offers optional premium subscription tiers (e.g., Lite, Pro) alongside our Free tier. By purchasing a subscription, you agree to the terms below and our detailed Paid Services Terms.
Under our shared billing model, only one partner in a connected couple relationship is required to hold an active paid subscription to unlock paid features, storage allocations, and premium perks for both connected accounts.
Payments are processed via authorized third-party platforms (Apple App Store, Google Play Store, Stripe, RevenueCat). We do not collect or store full payment credentials on our servers.
Subscriptions automatically renew at the end of each billing cycle (monthly or annually) unless auto-renew is turned off at least 24 hours before the current period ends via your store or account portal settings (Apple ID, Google Play, or Web Billing Portal). For step-by-step store instructions, please see our How to Cancel Subscription Guide.
Except as required by applicable law or specific app store policies, all purchases are strictly non-refundable. Unused subscription periods will not be refunded upon cancellation.
We reserve the right to modify subscription pricing at any time. Any price increases will be communicated to active subscribers at least 90 days in advance via in-app notices or email. Continued subscription after the notice period constitutes acceptance of the new price.
The App is provided on an "AS IS" and "AS AVAILABLE" basis. We do not guarantee that:
Cryptographic Risk Acknowledgment: You explicitly acknowledge that local hardware damage, operating system updates, or third-party device backup failures may disrupt local cryptographic key storage, causing a permanent loss of access to your historical messages and data. We are not liable for data recovery failure due to cryptographic errors, key corruption, or device incompatibility.
Modifications: We reserve the right to modify, suspend, or discontinue any part of the App at any time without liability to you.
You agree to defend, indemnify, and hold harmless Young Dai Zi Innovation and its employees, contractors, and agents from and against any and all claims, damages, obligations, losses, liabilities, costs, or debt, and expenses (including but not limited to attorney's fees) arising from:
To the maximum extent permitted by law, Young Dai Zi Innovation shall not be liable for any indirect, incidental, special, consequential, or punitive damages, including without limitation, loss of profits, data, use, goodwill, or other intangible losses, resulting from your access to or use of or inability to access or use the App, even if we have been informed of the possibility of such data loss through account locking or credential mismanagement.
These Terms shall be governed and constructed in accordance with the laws of Malaysia, without regard to its conflict of law provisions.
Please read this section carefully, as it affects your legal rights, including your right to file a lawsuit in court.
In the event of any dispute, controversy, or claim arising out of or relating to these Terms, including its formation, validity, breach, or termination (a "Dispute"), you and Young Dai Zi Innovation agree to first attempt to resolve the Dispute informally by contacting us at contact@youngdaizi.com. Parties shall engage in good-faith negotiations for a period of at least thirty (30) days from the date the Dispute is reported.
If the Dispute cannot be resolved informally within thirty (30) days, it shall be referred to and finally resolved by arbitration administered by the Asian International Arbitration Centre (AIAC) in accordance with the AIAC Arbitration Rules in force at the time of the commencement of the arbitration, which rules are deemed to be incorporated by reference into this clause.
To the maximum extent permitted by applicable law, you and Young Dai Zi Innovation agree that any arbitration or legal proceeding shall be conducted solely on an individual basis. Neither you nor we shall seek to have any Dispute heard as a class action, representative action, or collective proceeding. The arbitrator may not consolidate more than one person's claims without the express written consent of all parties involved.
We may terminate or suspend your account immediately, without prior notice or liability, for any reason whatsoever, including without limitation if you breach the Terms.
