CovalithStreak Privacy Policy
English
Effective date: 2026-09-08
Streak is a personal habit tracker for iPhone. Covalith is a brand operated by Jianzhong Li, an individual developer. This policy describes Streak's data practices and its related support pages. Contact: support@covalith.com.
Data on your device
Streak stores habit names, notes, schedules, check-ins, language preferences and imported daily Health progress locally on your device. The app has no account system, advertising, tracking, analytics SDK or developer-operated sync server. It does not upload your habits or Health records to Covalith or third parties.
Optional Apple Health access
With your permission, Streak reads only the Health types needed for goals you create: sleep analysis, recorded workouts and Apple Exercise Time. It calculates sleep duration, bedtime, workout minutes, workout sessions or Exercise ring progress locally. It does not write to or delete from Apple Health. Health data is not used for advertising, marketing or profiling and is not sold or shared by Streak.
Sync checks this month and the preceding 11 calendar months when you open the app or refresh. Previously imported older progress can remain cached. Streak cannot distinguish denied read access from missing records, so missing data stays unverified.
Retention and your choices
Local data remains until you remove it. Delete a habit to remove its saved history. In the Apple Health screen, disconnect to disable sync and clear imported progress while retaining manual check-ins. In Settings, Erase all app data removes habits and imported progress; language preferences remain. You may also revoke Streak's read permissions in the Health app. These actions never delete the original Health records.
Streak does not implement iCloud sync. Device backups may include app preferences according to your Apple backup settings; Apple manages those backups. Removing data from the current installation does not remove existing device backups. You control those through Apple's settings.
Support and website visits
If you email support@covalith.com, we receive your email address and the information you choose to send, solely to respond to your request. Please do not send Health records unless you intend to share them. Support email is handled through Google Workspace. Website delivery uses Cloudflare, which may process technical request information such as IP address and browser headers to deliver and secure the pages. Visiting a support link does not send your habit or Health database. We retain support correspondence only as needed to resolve requests and meet applicable legal obligations.
Your rights and changes
Depending on your location, you may have rights to access, correct or delete personal information you have sent to support, or object to or restrict its processing. Contact support@covalith.com to make a request. We cannot retrieve or erase app records stored only on your device. We will update this page and its effective date if these practices change. The English policy is the source text; the Chinese translation conveys the same practices.
Streak 隐私政策
生效日期：2026-09-08
Streak 是一款 iPhone 个人习惯记录应用。Covalith 是由个人开发者 Jianzhong Li 运营的品牌。本政策说明 Streak 及相关支持页面的数据处理方式。联系邮箱：support@covalith.com。
设备上的数据
Streak 在你的设备本地保存习惯名称、备注、频率、打卡记录、语言偏好以及导入的每日健康进度。应用没有账号系统、广告、跟踪、分析 SDK 或开发者运营的同步服务器，不会向 Covalith 或第三方上传你的习惯或健康记录。
可选的 Apple 健康读取
获得授权后，Streak 仅读取你创建的目标所需的健康类型：睡眠分析、运动记录和 Apple 锻炼时间，并在本地计算睡眠时长、入睡时间、运动分钟数、运动次数或锻炼圆环进度。Streak 不会写入或删除 Apple 健康记录，也不会将健康数据用于广告、营销或用户画像，不会出售或共享这些数据。
打开应用或刷新时，同步会检查本月及此前 11 个自然月。此前导入的更早进度可能继续保存在本地。Streak 无法区分读取权限被拒绝和记录缺失，因此缺少数据的目标保持未验证状态。
保存期限和你的选择
本地数据会保留至你将其移除。删除习惯会移除该习惯的已保存历史。在 Apple 健康页面断开连接，会关闭同步并清除导入进度，同时保留手动打卡。在设置中清除全部应用数据，会移除习惯和导入进度，但保留语言偏好。你也可以在健康 App 中撤销 Streak 的读取权限。这些操作都不会删除健康 App 中的原始记录。
Streak 不提供 iCloud 同步。设备备份可能根据你的 Apple 备份设置包含应用偏好数据，备份由 Apple 管理。从当前安装中删除数据不会删除已有的设备备份；你可以通过 Apple 设置管理备份。
支持邮件与网站访问
如果你发邮件至 support@covalith.com，我们会收到你的邮箱地址和你主动提供的信息，仅用于回复请求。除非你明确希望分享，请勿发送健康记录。支持邮件由 Google Workspace 处理。网站通过 Cloudflare 提供，后者可能处理 IP 地址、浏览器请求头等技术信息，以交付页面并保障安全。访问支持链接不会发送你的习惯或健康数据库。支持通信仅在解决请求和履行适用法律义务所需的期限内保留。
你的权利与政策更新
根据所在地法律，你可能有权访问、更正或删除发送给支持团队的个人信息，或反对、限制其处理。请联系 support@covalith.com 提出请求。我们无法读取或删除仅保存在你设备上的应用记录。如数据处理方式变化，我们会更新本页面及生效日期。英文政策为原文，中文译文表达相同的数据处理方式。
