Membership Purchase Agreement (including Auto-Renewal Terms)

This Agreement is made between you and Xiang Wei, developer and operator of Duo Wallpaper ("we"), an individual developer, regarding the purchase and use of the membership services of the App. It contains auto-renewal terms, so please read it carefully before purchasing. Monthly and annual memberships are auto-renewing subscriptions; unless cancelled, you will be automatically charged for renewal before the current period expires.

1. Membership Plans and Service Description

Plan	Type	Billing	Validity
Monthly membership	Auto-renewing subscription	Charged monthly	1 month from the date of purchase/renewal
Annual membership	Auto-renewing subscription	Charged yearly	12 months from the date of purchase/renewal
Lifetime membership	Non-consumable (one-time purchase)	One-time payment	Valid indefinitely (as long as the account exists)

1.1 Membership is tied to your account. Under the same Apple ID, membership status can sync across devices (via App Store transaction records).

1.2 Membership is for use within the App only and is non-transferable and may not be shared with other accounts (Apple Family Sharing, if applicable, is subject to Apple's policies).

2. Membership Benefits

2.1 Membership benefits are as displayed on the purchase page and typically include:

Unlocking members-only wallpaper content (including HD wallpapers, Live Photos, etc.);
Unlocking more categories, collections and download quota;
Early access to new features and content.

2.2 We may adjust membership benefits from time to time (including adding or modifying benefits); material adjustments will be announced in advance in the App. Benefit adjustments do not affect your current paid subscription period.

3. Pricing and Payment

3.1 Membership pricing is as displayed on the Apple App Store at the time of purchase and may vary due to Apple's pricing tiers, promotions or regional differences.

3.2 All payments are processed through Apple's in-app purchase system, and fees are charged to the payment method associated with your Apple ID. We never access or store your bank card or other payment information.

3.3 During a subscription period, membership benefits take effect immediately and are non-transferable; purchasing the same active subscription again does not extend its duration.

4. Auto-Renewal Terms

Important: Monthly and annual memberships are auto-renewing products. By subscribing, you authorize Apple to charge the payment method associated with your Apple ID for the next period within the 24 hours before each subscription period expires. If you do not wish to renew, please cancel at least 24 hours before the current period ends (see Section 5).

4.1 Charging time: Within the 24 hours before the current subscription period expires, Apple will automatically charge for the next period; upon successful charging, the subscription is extended by one period.

4.2 Failed charging: If a charge fails, Apple may attempt other payment methods linked to your Apple ID; if charging ultimately fails, the subscription ends at expiration and membership benefits lapse with it.

4.3 Cancellation does not end the current period: You may cancel auto-renewal at any time. After cancellation, your benefits remain valid until the end of the current subscription period, and no further charges will occur.

4.4 The lifetime membership is a one-time purchase and is not subject to auto-renewal.

5. Cancelling a Subscription

5.1 You may cancel auto-renewal at any time via the following paths:

iOS 13 and later: open "Settings" → tap your name at the top → "Subscriptions" → select the App's membership → turn off automatic renewal;
Or in the App Store app: tap your profile picture → "Account" → "Subscriptions" → select the subscription to cancel.

5.2 After cancellation, you can continue using your membership benefits until the end of the current subscription period.

5.3 Please cancel only via the official paths above; uninstalling the App or deleting your account will not stop auto-charging.

6. Restoring Purchases

6.1 If you switch devices, reinstall the App, or your membership status is not displayed correctly, tap "Restore Purchases" on the purchase page; the App will sync and restore your membership benefits via App Store transaction records.

6.2 Restoring purchases requires your device to be signed in with the same Apple ID used for the purchase and to be connected to the internet.

7. Refunds

7.1 In-app purchase transactions are processed and settled by Apple. Refund requests must be submitted through Apple's official channels:

Visit reportaproblem.apple.com, sign in with your Apple ID and request a refund; or
Contact Apple Support.

7.2 Whether a refund is granted is decided by Apple. If a refund succeeds, the corresponding membership benefits will be revoked by Apple's system, and the App will deactivate the membership accordingly.

7.3 If auto-renewal has already been charged and you no longer wish to renew, you may cancel the subscription and at the same time request a refund from Apple for the newly charged period.

7.4 If you are under 14 years of age, please purchase only with the consent and company of your guardian. For purchases made by a minor without guardian consent, the guardian may request a refund through Apple's official channels above with relevant proof.

8. Changes and Termination of Membership

Account deletion: After you delete your account, your membership terminates with the account; unexpired benefits cannot be transferred or refunded.
Violations: If you breach the Terms of Service (e.g., exploiting vulnerabilities, abusive refunds, attacking the service), we may suspend or terminate your membership as appropriate; fees already paid are in principle non-refundable.
Service termination: If membership services are discontinued due to business adjustments, we will announce in advance as required by law and properly handle your unconsumed benefits.

9. Disclaimer

9.1 For purchase failures or delayed activation of benefits caused by Apple service failures, payment channel failures, network anomalies or other reasons not attributable to us, we will assist you as much as possible but are not liable for indirect losses arising therefrom.

9.2 You understand and agree that content within the membership benefits may be removed or adjusted due to copyright expiration or similar reasons, and we will substitute it with comparable content.

10. Amendments and Contact

10.1 We may revise this Agreement according to business and legal requirements; revised versions will be published on this page, and material changes will be announced via in-app dialogs or announcements.

10.2 If you continue to purchase or use membership services after a revision takes effect, you are deemed to have accepted the revised Agreement.

10.3 If you have any questions about this Agreement or the membership services, please contact:
