Privacy Policy

Last Updated: September 28, 2026

This Privacy Policy describes how MomentSaver ("we", "us", or "our") collects, uses, and shares your information when you use our mobile application (the "App").

1. Information We Collect

1.1 Media and Files

MomentSaver is a video download and gallery application. To provide these services, we require access to your device's storage.

• Storage Access: On older Android versions, we request permission to read and write your device's external storage (READ_EXTERNAL_STORAGE, WRITE_EXTERNAL_STORAGE) to display, organize, and save your local video and image files.
• Media Access: On newer Android versions, we use specific media permissions (READ_MEDIA_IMAGES, READ_MEDIA_VIDEO) to access your gallery.
• Your media files are processed locally on your device and are not uploaded to our servers.

1.2 Clipboard and Shared Links

• Clipboard: When the "auto-read clipboard" setting is enabled (on by default), the App reads your clipboard when it is opened or brought to the foreground, to detect a supported share link and fill it in for you. Clipboard content is checked locally and is not uploaded. You can turn this off at any time in the App's settings.
• Link Parsing: To download content, the link you provide is sent directly from your device to the content platform it belongs to (for example Douyin, Xiaohongshu, Bilibili, YouTube). Links from X (Twitter) are resolved through the third-party service api.vxtwitter.com.

1.3 Usage Data and Diagnostics

We use Google Firebase to understand how the App is used and to fix problems:

• Firebase Analytics: Collects app usage events, such as whether a link was parsed successfully, which platform it came from, the type of error, download results, and subscription page views. It also collects standard information such as an app instance identifier, device model, OS version, app version, and approximate country or region.
• Firebase Crashlytics: Collects crash reports and error diagnostics, including stack traces and device state at the time of the error.
• Parsed Links: Each time you parse a link, whether it succeeds or fails, a redacted version of that link is recorded in Firebase Analytics, so we can see which content and platforms are used and keep parsing working. When a link fails to parse, the error report sent to Crashlytics also includes the redacted link, so we can reproduce and fix the problem. Before sending, we remove login information, fragments, and all query parameters except content identifiers (such as a video ID). Tracking parameters and share tokens are removed.

1.4 Purchases and Subscriptions

Subscriptions are processed by Google Play or the Apple App Store and managed through RevenueCat. We receive an anonymous app user identifier and your purchase and subscription status. We never receive or store your payment card details.

2. How We Use Information

We use the collected information for:

• Providing and maintaining the App's core functionality (parsing links, downloading, viewing, and managing media).
• Verifying your subscription status and unlocking paid features.
• Diagnosing crashes and parsing failures, and adapting to changes on supported platforms.
• Improving the App's performance and user interface.
• Responding to support requests or feedback.

3. Data Sharing and Disclosure

We do not sell, trade, or rent your personal information to third parties. Information is shared only with the service providers that help us operate the App, each processing it under its own privacy policy:

• Google Firebase (Analytics, Crashlytics): Firebase Privacy
• RevenueCat (subscription management): RevenueCat Privacy Policy
• Google Play / Apple App Store (payment processing)
• Content platforms and api.vxtwitter.com, which receive the links you choose to parse, as described in section 1.2.

We may also disclose information if required by law.

4. Data Retention

Media files stay on your device until you delete them. Analytics and diagnostic data are kept by the service providers above according to their retention periods, and are used only for the purposes described in this policy.

5. Your Choices

• You can disable automatic clipboard reading in the App's settings.
• You can revoke storage or media permissions at any time in your device's system settings.
• You can manage or cancel your subscription in Google Play or the App Store.
• To request deletion of data associated with you, contact us at the email below.

6. Security

We value your trust in providing us your information, thus we are striving to use commercially acceptable means of protecting it. But remember that no method of transmission over the internet, or method of electronic storage is 100% secure and reliable, and we cannot guarantee its absolute security.

7. Changes to This Policy

We may update this Privacy Policy from time to time. Changes take effect when posted on this page, and the "Last Updated" date above will be revised.

隐私政策

最后更新日期：2026年9月28日

本隐私政策详细说明了 MomentSaver（以下简称“我们”或“本应用”）在您使用我们的移动应用程序时，如何收集、使用和分享您的信息。

1. 我们收集的信息

1.1 媒体和文件

MomentSaver 是一款视频下载和相册应用。为了提供这些服务，我们需要访问您设备的存储空间。

• 存储访问权限：在较旧的 Android 版本上，我们请求读取和写入设备外部存储的权限（READ_EXTERNAL_STORAGE、WRITE_EXTERNAL_STORAGE），用于显示、整理和保存您本地的视频和图像文件。
• 媒体访问权限：在较新的 Android 版本上，我们使用特定的媒体权限（READ_MEDIA_IMAGES、READ_MEDIA_VIDEO）来访问您的图库。
• 您的媒体文件仅在设备本地处理，不会上传到我们的服务器。

1.2 剪贴板与分享链接

• 剪贴板：开启“自动读取剪贴板”设置（默认开启）时，本应用会在启动或回到前台时读取剪贴板，以识别受支持的分享链接并自动填入。剪贴板内容仅在本地判断，不会上传。您可以随时在应用设置中关闭此功能。
• 链接解析：为下载内容，您提供的链接会从您的设备直接发送到其所属的内容平台（例如抖音、小红书、哔哩哔哩、YouTube）。X（推特）链接会通过第三方服务 api.vxtwitter.com 解析。

1.3 使用数据与诊断信息

我们使用 Google Firebase 了解应用的使用情况并修复问题：

• Firebase Analytics：收集应用使用事件，例如链接是否解析成功、所属平台、错误类型、下载结果以及订阅页面的浏览情况；同时收集应用实例标识符、设备型号、操作系统版本、应用版本及大致所在国家或地区等标准信息。
• Firebase Crashlytics：收集崩溃报告和错误诊断信息，包括错误发生时的堆栈信息和设备状态。
• 解析链接记录：每次解析链接时，无论成功或失败，该链接的脱敏版本都会记录到 Firebase Analytics，以便我们了解常用的内容和平台，并保证解析功能正常；当链接解析失败时，发送到 Crashlytics 的错误报告也会包含该脱敏链接，以便我们复现并修复问题。发送前，我们会去除链接中的登录信息、片段（# 之后的部分），以及除内容标识（如视频 ID）以外的所有查询参数；追踪参数和分享令牌都会被去除。

1.4 购买与订阅

订阅通过 Google Play 或 Apple App Store 处理，并由 RevenueCat 进行管理。我们会获得一个匿名的应用用户标识符以及您的购买和订阅状态。我们不会接收或存储您的支付卡信息。

2. 我们如何使用信息

我们将收集的信息用于：

• 提供和维护应用的核心功能（解析链接、下载、查看和管理媒体）。
• 验证您的订阅状态并解锁付费功能。
• 诊断崩溃和解析失败问题，并适配受支持平台的变化。
• 改进应用的性能和用户界面。
• 回复支持请求或反馈。

3. 数据共享与披露

我们不会向第三方出售、交易或出租您的个人信息。信息仅与协助我们运营本应用的服务提供商共享，它们各自依据其隐私政策处理数据：

• Google Firebase（Analytics、Crashlytics）：Firebase 隐私说明
• RevenueCat（订阅管理）：RevenueCat 隐私政策
• Google Play / Apple App Store（支付处理）
• 内容平台及 api.vxtwitter.com：接收您选择解析的链接，详见第 1.2 节。

在法律要求的情况下，我们也可能披露相关信息。

4. 数据保留

媒体文件保存在您的设备上，直到您自行删除。使用数据和诊断数据由上述服务提供商按其保留期限保存，且仅用于本政策所述目的。

5. 您的选择

• 您可以在应用设置中关闭自动读取剪贴板。
• 您可以随时在设备系统设置中撤销存储或媒体权限。
• 您可以在 Google Play 或 App Store 中管理或取消订阅。
• 如需删除与您相关的数据，请通过下方邮箱联系我们。

6. 数据安全

我们非常重视您对我们的信任，因此我们正努力使用商业上可行的方法来保护您的信息。但请记住，互联网上的传输方法或电子存储方法都不是 100% 安全可靠的，我们无法保证其绝对安全性。
