隐私政策

生效日期：2026 年 9 月 18 日

本政策说明 MetaD 元点钱包（以下简称“本应用”）如何处理你的信息。本应用由 MetaD Labs Inc.（以下简称“我们”）提供。

本应用是非托管钱包。你的助记词、私钥和钱包密码只以加密形式保存在你自己的设备上，我们无法读取，也从不上传到任何服务器。

我们不收集的信息

助记词、私钥、钱包密码和 PIN 码。
姓名、手机号、身份证件等身份信息。使用本应用不需要注册账号。
面容或指纹数据。生物识别由手机系统完成，本应用只获得“验证通过或失败”的结果。
通讯录、相册和位置信息。

保存在你设备上的信息

以下数据只存储在本机的系统安全存储区（iOS 钥匙串或 Android Keystore），不随云备份迁移，删除应用或钱包后即被清除：加密后的钱包、应用设置、代币列表、地址簿、已连接网站、本应用发出的最近交易记录。

与第三方服务的通信

为实现钱包功能，本应用需要与以下服务通信。这些请求可能让对方看到你的 IP 地址，以及查询的钱包地址等公开信息：

区块链节点（RPC）：查询余额、估算手续费、广播你确认过的交易。钱包地址和交易在区块链上本身是公开的。
CoinGecko：获取代币价格，用于估值显示，可在设置中关闭。
图标服务：从 GitHub 上的公共素材库加载代币图标，从 Google 加载网站图标。
崩溃报告（Sentry）：应用发生错误时，发送错误信息、设备型号、系统版本和应用版本，帮助我们修复问题。报告中不包含助记词、私钥、密码、钱包地址或余额。
应用更新（Expo）：检查并下载应用的更新包。
版本检查：从我们的网站读取最新版本号，提醒你升级。

内置浏览器与 DApp

你在内置浏览器中访问的网站和去中心化应用（DApp）由第三方运营，适用其各自的隐私政策。只有在你点击确认连接后，网站才能读取你的钱包地址；每一笔交易和签名都需要你单独确认。你可以随时在设置中断开已连接的网站。

设备权限

相机：仅用于扫描收款地址二维码，画面不会保存或上传。
面容 ID / 指纹：仅在你开启后用于解锁和确认交易。

数据安全

钱包数据使用 scrypt 派生密钥加密，并存放在系统安全存储区。本应用会在显示助记词时禁止截屏，在切换到后台时遮挡界面。请妥善保管助记词：我们无法帮你找回丢失的助记词或密码，任何以“客服”名义索要助记词的都是诈骗。

未成年人

本应用面向成年人。未满 18 周岁的用户应在监护人同意和指导下使用。

政策更新

我们可能会更新本政策，更新后的版本会发布在本页面并标明生效日期。重大变更会在应用内提示。

联系我们

如对本政策有任何疑问，请发送邮件至 jeremyli@metad.app。

Privacy Policy

Effective date: September 18, 2026

This policy explains how MetaD Wallet (the “App”) handles your information. The App is provided by MetaD Labs Inc., a Colorado corporation (“we” or “us”).

The App is a non-custodial wallet. Your recovery phrase, private keys and wallet password are stored only in encrypted form on your own device. We cannot read them, and they are never uploaded to any server.

Information we do not collect

Recovery phrases, private keys, wallet passwords and PINs.
Identity information such as your name, phone number or ID documents. No account registration is required to use the App.
Face or fingerprint data. Biometric authentication is handled by your phone’s operating system; the App only receives a pass or fail result.
Contacts, photos and location.

Information stored on your device

The following data is stored only in your device’s secure system storage (iOS Keychain or Android Keystore). It is not migrated through cloud backups and is erased when you delete the App or the wallet: your encrypted wallet, app settings, token list, address book, connected websites, and recent transactions sent from the App.

Communication with third-party services

To provide wallet functions, the App communicates with the services below. These requests may reveal your IP address and public information such as the wallet addresses being queried:

Blockchain nodes (RPC): to check balances, estimate fees and broadcast transactions you have confirmed. Wallet addresses and transactions are public on the blockchain by nature.
CoinGecko: to fetch token prices for value display. This can be turned off in Settings.
Icon services: token icons are loaded from a public asset repository on GitHub, and website icons from Google.
Crash reporting (Sentry): when an error occurs, the App sends the error details, device model, OS version and app version to help us fix problems. Reports never include recovery phrases, private keys, passwords, wallet addresses or balances.
App updates (Expo): to check for and download app updates.
Version check: to read the latest version number from our website and remind you to upgrade.

Built-in browser and DApps

Websites and decentralized applications (DApps) you visit in the built-in browser are operated by third parties and are governed by their own privacy policies. A website can read your wallet address only after you tap to approve the connection, and every transaction and signature requires your separate confirmation. You can disconnect websites at any time in Settings.

Device permissions

Camera: used only to scan address QR codes. Images are never saved or uploaded.
Face ID / fingerprint: used only for unlocking and confirming transactions, and only if you enable it.

Data security

Wallet data is encrypted with a key derived using scrypt and kept in secure system storage. The App blocks screenshots while your recovery phrase is displayed and hides the screen when moved to the background. Please keep your recovery phrase safe: we cannot recover a lost recovery phrase or password for you, and anyone claiming to be “customer support” who asks for your recovery phrase is a scammer.

Minors

The App is intended for adults. Users under 18 should use it only with the consent and guidance of a parent or guardian.

Changes to this policy

We may update this policy. The updated version will be posted on this page with its effective date, and significant changes will be announced in the App.
