拾刻 Signet · 隐私政策Signet · Privacy Policy
你盖章留下的一切——照片、文字、日期、印章、印文——全部只存储在你的设备本地（及你自己的 iCloud 设备备份中）。我们没有服务器存储你的内容，没有账户体系，看不到、也不想看到你留下的任何一刻。Everything you seal — photos, text, dates, stamps, inscriptions — is stored exclusively on your device (and your own iCloud device backup). We have no servers storing your content, no account system, and no ability or desire to see any moment you keep.
1. 我们不收集什么1. What we do NOT collect
- 你的照片、文字、印文、边款等一切内容——永不上传Your photos, text, seal inscriptions, colophons — never uploaded
- 姓名、邮箱、电话等个人身份信息Names, emails, phone numbers, or any personal identifiers
- 位置信息Location data
- 广告标识符；本应用无任何广告或第三方分析 SDKAdvertising identifiers; this app contains no ads and no third-party analytics SDKs
2. 我们收集什么（匿名使用统计，可关闭）2. What we collect (anonymous usage stats, opt-out available)
为了知道产品是否好用，应用会发送极少量匿名事件到我们自己的统计服务（不经过任何第三方）：To understand whether the product works well, the app sends a minimal set of anonymous events to our own analytics service (no third parties involved):
- 事件名（如「启动」「完成一次盖章」「导出一次」）——不含任何内容本身Event names (e.g. "launch", "completed a stamp", "exported") — never including any content
- 应用版本号与 iOS 版本号App version and iOS version
- 一个随机生成的设备匿名编号（与你的身份无关，服务端再经加盐哈希，不可反查）A randomly generated anonymous device ID (unrelated to your identity; salted-hashed server-side, irreversible)
你可以随时在 App 内「设置」中关闭匿名使用统计，关闭后不再发送任何数据。You can disable anonymous usage statistics at any time in the app's Settings. Once disabled, no data is sent.
3. 照片权限的用途3. How photo permissions are used
- 选取照片：使用系统照片选择器，应用只拿到你主动选中的那张。Selecting photos: uses the system photo picker; the app only receives the photo you actively choose.
- 读取拍摄时间：为了让盖章留住的是「拍摄那一刻」，应用会读取所选照片的拍摄日期；照片本身不会离开你的设备。Reading capture date: so the seal preserves "the moment it was taken," the app reads the photo's capture date; the photo itself never leaves your device.
- 保存到相册：仅在你主动点击「保存」时，把你盖好章的成品图写入相册。Saving to library: only when you explicitly tap "Save," the finished sealed image is written to your photo library.
4. 数据的存储与删除4. Data storage and deletion
全部数据存储于设备本地数据库。删除 App 即删除全部数据（如你启用了 iCloud 设备备份，请一并管理）。App 内删除某一刻或磨去某方印，即时生效、无法找回。All data is stored in the on-device local database. Deleting the app deletes all data (manage iCloud device backups separately if enabled). Deleting a moment or grinding away a seal within the app takes effect immediately and is irreversible.
5. 儿童5. Children
本应用不面向 13 岁以下儿童设计，也不会有意收集儿童的任何信息。应用内无账户、无社交功能、无用户生成内容的公开展示。This app is not designed for children under 13 and does not knowingly collect any information from children. There are no accounts, no social features, and no public display of user-generated content.
6. 本政策的变更6. Changes to this policy
若本政策有实质性变更，我们会更新本页顶部的「最后更新」日期。涉及数据收集范围扩大的变更，会在应用内明确告知。If this policy changes materially, we will update the "Last updated" date at the top of this page. Changes that expand the scope of data collection will be clearly communicated within the app.
