Stamp Designer VIP Membership Agreement

Last updated: June 26, 2026
Effective date: June 26, 2026

Please read this VIP Membership Agreement carefully before purchasing, activating, or using VIP membership services in Stamp Designer (the "App"). By ticking the agreement checkbox, completing payment, using an activation code, or continuing to use membership benefits, you agree to this Agreement.

1. Service Provider

The membership service provider under this Agreement depends on the channel through which you obtain, download, or use the App:

• For versions released, downloaded, or used through Android app stores in mainland China, the service provider is Hefei Xixia Network Technology Co., Ltd., registered at Area A, 5th Floor, Building A, Zhongrui Building Research Building, Intersection of Hongfeng Road and Kexue Avenue, High-tech Zone, Hefei, Anhui, China.
• For versions released, downloaded, or used through Apple App Store, Google Play, or other overseas/international app stores, the service provider is the individual developer Shi Xiuwen, as shown on the relevant app store page.
• In this Agreement, "we", "developer", or "service provider" refers to the corresponding entity above for the distribution channel you use.

2. Membership Benefits

VIP membership is a virtual digital benefit provided by the App. It may include advanced seal styles, advanced editing capabilities, unlimited seal creation, image saving, watermark-free export, HD export, document stamping, batch or advanced processing capabilities, and other membership features shown in the App. Specific benefits are subject to the purchase page, feature pages, membership page, and actual app version.

We may reasonably adjust the scope, display, and details of membership benefits according to product updates, material updates, app store review requirements, technical conditions, or operational needs.

3. Purchase, Payment, and Activation

• Purchasing VIP membership does not necessarily require signing in. You may purchase membership without signing in, and benefits usually take effect first on the current device. Sign-in is mainly used when you voluntarily sync benefits across devices, handle order support, or use account-related services.
• Membership purchases on iOS are generally completed through Apple in-app purchase. Payment, billing, refunds, and account management are governed by Apple's rules.
• Membership purchases on Google Play Android are generally completed through Google Play Billing. Payment, billing, refunds, and account management are governed by Google Play's rules.
• Domestic Android versions may support WeChat Pay, activation codes, or other activation methods allowed by the relevant app store. The actual methods are subject to the in-app display and platform rules.
• Activation codes are virtual benefit credentials for one-time or conditional use. Please keep them safe. You are responsible for consequences caused by leakage, transfer, incorrect input, expiration, or failure to meet use conditions.
• Membership benefits usually take effect after successful payment or activation. If benefits do not take effect promptly due to network issues, system issues, platform order status, or server synchronization delay, please refresh membership status, restore purchases, or contact us for support.

4. Validity Period and Renewal

Membership services take effect for the period shown on the purchase page. Available types may include monthly, quarterly, yearly, lifetime membership, or other types shown in the App. In the iOS version, monthly, quarterly, and yearly memberships are generally Apple non-renewing subscriptions, and lifetime membership is generally a one-time non-consumable purchase.

Non-renewing subscriptions do not renew automatically. After the membership period expires, you need to purchase the corresponding membership service again in the App if you wish to continue using membership benefits. The validity period is subject to the membership type you actually purchase or activate, order records, activation records, and server/local records.

5. Refunds

Membership services are virtual digital benefits. Unless otherwise required by applicable laws, Apple, Google Play, domestic app stores, or payment platform rules, membership benefits generally cannot be refunded without cause once activated.

Refunds for iOS orders should be requested through Apple's official channels and are subject to Apple's review. Refunds for Google Play orders should be requested through Google Play's official channels and are subject to Google Play's review. Refunds for other Android orders may be handled according to WeChat Pay, the relevant app store, or payment platform rules.

6. Usage Restrictions

• You must not obtain or use membership benefits by cracking, bypassing payment, improperly sharing accounts, reselling activation codes, malicious refunds, batch registration, or similar improper methods.
• You must not use membership benefits for illegal activities, infringement of others' rights, disruption of platform order, or damage to the developer's lawful rights and interests, especially for imitating, forging, or altering seals or false certificates.
• If you violate this Agreement or applicable laws and regulations, we may suspend, restrict, or terminate the relevant membership benefits within a reasonable scope and reserve the right to pursue liability.

7. Agreement Updates

We may update this Agreement according to laws and regulations, app store requirements, functional changes, or operational needs. The updated Agreement will be displayed in the App or on relevant pages. Your continued use of membership services means that you accept the updated Agreement.
