We reserve the right to modify, suspend, or discontinue features, and will provide reasonable notice where possible.

To provide the service, you grant us a limited licence to process your content only as necessary for:

• Storing your content on our servers for synchronisation and access
• Transmitting necessary content to AI service providers for AI diary generation, question recommendation, AI profile summary, or similar AI features (only when you use those features)
• Processing and formatting your content when you use the export feature
• Saving and displaying optional information such as location, images, mood, weather, and tags together with the relevant diary or note where you choose to add them

This licence is limited to what is necessary to operate the service and does not include using your content for marketing, advertising, or other commercial purposes.

3.3 Content Standards

• You are solely responsible for the content you create

3.4 Copyright Complaints

If you believe content in the App infringes your copyright or other intellectual property rights, please send us a notice using the contact below, including the following:

1. A description of the work you claim has been infringed
2. The location of the content you believe is infringing
3. Your contact information
4. A statement as to the truthfulness of the above

We will review and handle valid notices as soon as practicable.

4. AI Service Terms

When using AI diary generation, AI question recommendation, AI profile summary, or similar AI features, please note:

• AI-generated content is based on your notes and is for reference only
• AI output may not be fully accurate, complete, or appropriate; you are responsible for reviewing and editing before saving

• We make no guarantees regarding the accuracy, completeness, suitability, or legality of AI-generated content
• AI-generated content is not medical, psychological, legal, financial, or other professional advice and should not be used as the sole basis for important decisions
• Once you confirm and save AI-generated content, it becomes your personal content and your responsibility
• AI services may be temporarily unavailable due to third-party provider issues; we will try to restore them but do not guarantee continuous availability

5. VIP Membership

5.1 Subscription and Payment

• VIP members enjoy additional premium features and higher usage limits
• VIP subscriptions are offered in two tiers: monthly and yearly. Specific durations and prices are as displayed in the in-app purchase sheet
• All payments are processed through Apple In-App Purchase, and payment will be charged to your Apple ID account at confirmation of purchase
• Use of the App is also governed by Apple's standard end-user licence agreement (EULA). See Apple EULA
• If the in-app description differs from Apple's purchase sheet, the App Store, or Apple's applicable rules, Apple's displayed information and applicable rules control

5.2 Free Trial

• New users may be eligible for a one-time free trial period (duration as displayed in the App)
• Each user is entitled to one free trial only

5.3 Auto-Renewal and Cancellation

• Subscriptions auto-renew according to your selected plan (monthly / yearly)
• Unless you cancel at least 24 hours before the end of the current period, the subscription will automatically renew, and the renewal charge will match the price of the current subscription (unless Apple notifies you of a price change and obtains your consent)
• Renewal charges are deducted from your Apple ID account within 24 hours before the current period ends
• After cancellation, VIP benefits continue until the end of the current subscription period; any unused portion of a paid period is non-refundable, except as provided by Apple's applicable rules

5.4 Refund Policy

5.5 Price Changes

13. Governing Law and Dispute Resolution

13.1 Governing Law

• Subject to the mandatory provisions below, these Terms are governed by the laws of the Republic of Singapore, without regard to its conflict of laws rules
• Any disputes arising from these Terms shall first be resolved through good-faith negotiation; you may first contact us at support@niannian.app, and we will try to resolve the matter within a reasonable period
• If negotiation fails, then, except as otherwise provided in Section 13.2 (which applies to U.S. users), either party may bring proceedings in the courts of competent jurisdiction in Singapore

13.2 U.S. Users: Arbitration and Class Action Waiver

• Informal resolution first: Before starting arbitration, you agree to first describe the dispute to us at support@niannian.app, and both parties will make a good-faith effort to resolve it informally within 60 days
• Binding individual arbitration: If not resolved, any dispute between you and us arising from these Terms or the App will be finally resolved by binding individual arbitration administered by the American Arbitration Association (AAA) under its applicable consumer arbitration rules, rather than in court (except for small-claims matters below)
• Class action waiver: You and we each agree to bring claims only in an individual capacity and waive the right to participate in any class action, class arbitration, or representative proceeding as a plaintiff or class member; the arbitrator may not consolidate more than one person's claims
• Small-claims exception: Either party may bring an eligible dispute in a competent small-claims court
• 30-day opt-out: You may opt out of this arbitration and class action waiver section by emailing support@niannian.app (stating your account email and your election to opt out of arbitration) within 30 days of first accepting these Terms; opting out does not affect the rest of these Terms
• This arbitration provision is governed by the U.S. Federal Arbitration Act (FAA); if the class action waiver is found unenforceable as to a particular dispute, that dispute shall be resolved in court rather than by arbitration

13.3 Local Mandatory Consumer Rights

• If you are located outside Singapore (including but not limited to Japan, South Korea, Hong Kong SAR, Macao SAR, Taiwan, Malaysia, Thailand, the Philippines, Australia, New Zealand, the United States, and Canada), and the mandatory consumer protection laws of your jurisdiction grant you stronger rights, require the application of local law, or require disputes to be heard locally, those mandatory provisions prevail and are not limited by these Terms

14. General Provisions

• Entire agreement: These Terms, together with the Privacy Policy, constitute the entire agreement between you and us regarding the use of the App
• Severability: If any provision of these Terms is found to be invalid or unenforceable, it will be modified to the minimum extent necessary to make it valid, and the remaining provisions shall remain in full force and effect
• No waiver: Our failure to exercise or enforce any right or provision of these Terms does not constitute a waiver of that right or provision
• Assignment: You may not assign your rights or obligations under these Terms without our prior written consent
• Apple as third-party beneficiary: You acknowledge and agree that Apple Inc. and its subsidiaries are third-party beneficiaries of these Terms. Upon your acceptance of these Terms, Apple will have the right (and will be deemed to have accepted the right) to enforce these Terms against you as a third-party beneficiary
• Apple's standard EULA: In addition to these Terms, your use of the App is also governed by Apple's standard end-user licence agreement (EULA). See Apple EULA. If these Terms conflict with the Apple EULA, the stricter of the two applies
