Privacy Policy

01Scope and contact

This policy applies to the DevAsset app and its official website, developed by Tianming Guan. For privacy questions, contact avpsky@qq.com. The data practices of independent template projects you download depend on their implementation after you modify, run, or publish them.

02Everyday use and on-device processing

You do not need to register an account to browse examples. The app does not include third-party advertising or behavioral analytics SDKs, sell personal information, or use your activity for cross-app advertising tracking. Demo settings, interface inputs, and photo previews are processed primarily on your device and are not actively uploaded by the app to a developer server.

When you choose to copy code or the email address, the app writes the selected content to your system clipboard. Downloaded templates are saved to the Mac folder you choose; you can manage or delete these files yourself.

03Photos, hand tracking, and system authorization

Photo-selection demos use the system photo picker to access only the photos you choose for the current preview. The app does not actively upload those photos. Hand-tracking demos on Apple Vision Pro use system-authorized hand joint data to drive demo entities on device; the developer does not save or upload that data. You can manage permissions in system settings.

The Sign in with Apple demo starts system authorization and requests name and email scopes. The current demo only handles the success or failure state; it does not create an app account or persist or upload identity information returned by authorization. The Apple Pay button demo displays button styles and does not itself submit a payment request.

04Purchases and Apple services

In-app purchases and purchase restoration are handled through Apple StoreKit. The app uses verified transactions and product identifiers to determine unlock status. The developer does not receive your bank card details or payment credentials from the app. Apple handles account, payment, and related transaction information under its own privacy policy.

Map demos use Apple MapKit to load map content and do not request your current location. Map services, Apple documentation, the App Store, and other linked Apple services process information under their respective policies.

05Template downloads and network requests

When you choose to download a template, the app connects to template resources hosted on Alibaba Cloud Object Storage Service (OSS). Delivery requires network requests. The relevant service receives necessary technical information, such as your IP address and the requested resource, and may maintain service logs for delivery and security. Current resource URLs are in a US West region, so requests may involve cross-border transmission.

The developer does not use these requests for advertising profiles. Data handling, log retention, and security measures for cloud infrastructure and Apple services are managed by the respective providers.

06Support email

If you contact avpsky@qq.com, we receive your email address and the issue details, screenshots, or attachments you choose to provide. We use them to reply, investigate, and handle your request. Messages are delivered and stored through email services. Please do not send passwords, payment credentials, or unrelated sensitive information.

We retain support messages only as needed to address requests, follow up, and meet applicable obligations. You can contact the same address to request access, correction, or deletion of information you provided, except for records we must retain under applicable law.

07This website and external links

This website does not add third-party advertising or behavioral analytics scripts, or set cookies for advertising or behavioral profiling. Language switching uses page URLs without storing a language preference. Hosting and network providers may process IP addresses, request times, browser information, and security logs to deliver the website and prevent abuse.

This website links to the App Store, Apple privacy notices, and other external services. When you open an external service or send an email, the respective provider's privacy policy also applies.

08Your choices and policy updates

You can stop using a feature, revoke permissions in system settings, or delete files you downloaded. The app does not create a developer account, so there is no app-account deletion process. To make a request about information you provided in support emails, contact the address above.

We will update this policy when features or data practices change and show the updated date on this page. If a change requires additional authorization, we will explain and request it when you use the relevant feature.
