引言
TickerLocus（以下称“我们”）运营 Twintrail（轨迹陪伴打卡，以下简称“本应用”）。我们深知个人信息对你的重要性，将按照《中华人民共和国个人信息保护法》《中华人民共和国网络安全法》等法律法规及本政策保护你的个人信息。
你勾选同意或实际使用本应用，即表示你已阅读并同意本政策的全部内容。本政策仅适用于本应用提供的服务，不适用于第三方产品与服务（如 Apple 提供的登录、支付服务）。
一、我们收集的信息
本应用以“本地优先”为原则设计：你的打卡明细、坚持统计、会员限制状态等默认只保存在你的设备本地（iOS 系统沙盒数据库 / 浏览器本地存储），非经你主动操作不会上传。我们收集的信息包括：
- 账号信息：你使用“通过 Apple 登录”注册/登录时，我们会获取 Apple 提供的账号标识、你授权共享的邮箱与姓名，并保存你设置的昵称与头像（含高级会员上传的相册头像照片）。
- 打卡与关系数据：你的打卡日期与时间、绑定邀请码、关系类型（情侣/爱人/兄弟/闺蜜/知己等）、关系建立与解除时间、每日打卡提醒的偏好设置。
- 排行榜公开信息：你参与全球排行榜时，你的昵称、头像、地区标签、连续打卡天数、关系形态及绑定对象昵称/头像将按功能设定向其他用户公开展示。
- 互动内容：你为宠物设置的名称、喂养记录；你主动输入的其他内容。
- 我们不会收集你的通讯录、精确位置、短信、通话记录等与服务无关的信息；应用内不包含广告追踪类第三方 SDK。
二、信息的存储与期限
本地数据：打卡明细流水、累计统计、会员限制状态、自定义头像原图等仅保存在你的设备本地，我们无法访问；卸载应用或按你操作清除后即永久删除。
云端数据：为支持绑定关系、实时通知、全球排行榜与会员权益跨设备生效，以下内容会存储在云端（由第三方云服务商 Supabase 提供托管服务器）：账号资料、打卡日期摘要（不含明细）、绑定关系、会员状态、宠物资料、通知记录。
保存期限：除法律法规另有规定外，上述云端数据在你注销账号前持续保存；注销机制见本政策“你的权利”一节。
三、我们如何使用信息
- 提供核心功能：打卡记录与统计、绑定关系双方的状态同步与提醒、排行榜排名展示、每日打卡提醒；
- 会员权益校验：判断并展示你的会员资格（一次性买断，仅对你本人生效）；
- 安全与合规：识别异常登录、防止作弊（如同一日期重复打卡、虚假排名）、履行法律义务；
- 服务改进：以去标识化/匿名聚合形式分析功能使用情况（如无必要我们不做个体画像）。
四、信息的共享、委托与公开
除以下情形外，我们不会向任何第三方提供你的个人信息：
- 按你的授权公开：你参与排行榜及绑定关系时，前述“排行榜公开信息”将对其他用户可见，绑定对象也能看到你的昵称与头像。
- 第三方服务商：云存储服务商（存储与数据库）、Apple（账号登录认证、App Store 应用内购买与恢复购买、推送所需系统能力）。我们仅向其提供实现功能所必需的信息，并要求其依法处理。
- 法律要求：依法律法规、监管要求或有权机关要求提供。
- 本应用不向你发送任何广告，不将你的信息用于广告定向营销。
五、你的权利
- 查看与更正：你可随时在本应用“我的”页查看并修改昵称、头像、语言、主题等资料；
- 退出绑定：你可解除与关系对象的绑定（主动解除方存在 24 小时冷却限制，高级会员除外）；
- 撤回授权：你可撤回对 Apple 共享邮箱/姓名的授权（不影响使用基础登录功能）；
- 注销账号：你可在“我的 → 关于与账户 → 账户安全”中申请注销。注销将把你的账号标记为注销状态并使其从排行榜、可绑定列表中下线；本机本地数据将被清除；账号云端数据为你保留，注销后 7 天内同一 Apple 账号不能重新登录，期满重新登录即可自动恢复账号与已购会员权益。
- 投诉与救济：如你认为我们未妥善处理你的个人信息，可与我们联系，也可向个人信息保护主管部门投诉举报。
六、未成年人保护
本应用面向成年人及年满 14 周岁以上的未成年人。若你未满 14 周岁，请在监护人阅读并同意本政策及《用户协议》后，由监护人协助你使用；我们不会专门面向 14 周岁以下未成年人提供服务或主动收集其个人信息。
如果我们发现在未获监护人同意的情况下收集了 14 周岁以下未成年人的个人信息，将设法尽快删除。
七、信息安全
我们采取行业通行的安全措施保护你的信息：网络传输采用加密通道（HTTPS/TLS）；云端访问实行最小权限与访问控制；我们仅收集实现功能所必需的最少信息。
但请注意，任何安全措施都无法做到百分之百。如发生个人信息安全事件，我们将依法采取补救措施，并以推送通知/站内信等方式告知你，必要时向监管机构报告。

Introduction
TickerLocus ("we") operates Twintrail ("the App"). We understand how important your personal information is, and we protect it in accordance with the Personal Information Protection Law of the PRC, the Cybersecurity Law of the PRC and this Policy.
By ticking the consent box or actually using the App, you confirm that you have read and agree to this Policy in full. This Policy applies only to the services provided by the App, not to third-party products or services (such as Apple's sign-in and payment services).
1. Information We Collect
The App is designed "local-first": your check-in details, streak statistics and membership-limit status are by default stored only on your device (iOS sandbox database / browser local storage) and are not uploaded unless you actively do so. The information we collect includes:
- Account info: when you register/sign in with Apple, we receive the account identifier from Apple, the email and name you authorise to share, and we store the nickname and avatar you set (including album photos uploaded by Premium members).
- Check-in and relationship data: your check-in date and time, invite code, relationship type (couple/lover/brothers/sisters/confidant, etc.), when relationships start and end, and your daily reminder preference.
- Public leaderboard info: when you join the global leaderboard, your nickname, avatar, region tag, streak days, relationship type and your partner's nickname/avatar are shown publicly to other users as part of the feature.
- Interactive content: the pet name and feeding records you set, and other content you voluntarily enter.
- We do not collect your contacts, precise location, SMS or call records; the App contains no ad-tracking third-party SDKs.
2. Storage and Retention
Local data: check-in records, cumulative statistics, membership-limit status and original custom avatars are stored only on your device; we cannot access them. They are permanently deleted when you uninstall the App or clear them yourself.
Cloud data: to support pairing, real-time notifications, the global leaderboard and cross-device membership benefits, the following is stored in the cloud (hosted by third-party provider Supabase): account profile, check-in date summaries (no details), relationships, membership status, pet data and notification records.
Retention: unless otherwise required by law, the above cloud data is kept until you delete your account; see the "Your Rights" section of this Policy.
3. How We Use Information
- Providing core features: check-in records and statistics, status sync and reminders between partners, leaderboard display and daily reminders;
- Verifying membership benefits: determining and displaying your membership (a one-time purchase, valid only for you);
- Security and compliance: detecting abnormal sign-ins, preventing cheating (e.g. duplicate check-ins on the same day, fake rankings) and meeting legal obligations;
- Service improvement: analysing feature usage in de-identified/aggregated form (we do not build individual profiles unless necessary).
4. Sharing, Entrustment and Disclosure
Except in the following cases, we do not provide your personal information to any third party:
- Disclosure authorised by you: when you join the leaderboard or pair with someone, the "public leaderboard info" above is visible to other users, and your partner can see your nickname and avatar.
- Third-party providers: cloud storage provider (storage and database) and Apple (account sign-in, App Store in-app purchase and restore, system capabilities for notifications). We provide only what is necessary and require lawful processing.
- Legal requirements: disclosure required by laws, regulations, regulatory requirements or competent authorities.
- The App sends you no advertising and does not use your information for targeted ad marketing.
5. Your Rights
- Access and correction: view and edit your nickname, avatar, language, theme and other profile details anytime under "Mine";
- Unpairing: you may unpair from your partner (the initiating side has a 24-hour cooldown, except Premium members);
- Withdrawing consent: you may withdraw your authorisation to share your email/name with Apple (basic sign-in still works);
- Account deletion: apply under "Mine → About & account → Account security". Deletion marks your account as deleted and removes it from the leaderboard and pairable list; local data is cleared; cloud data is kept for you. The same Apple account cannot sign in for 7 days, after which signing in restores your account and purchased membership.
- Complaints and remedies: if you believe we have not handled your personal information properly, contact us or lodge a complaint with the personal information protection authority.
6. Protection of Minors
The App is intended for adults and minors aged 14 or above. If you are under 14, please use it with a guardian's assistance after they have read and agreed to this Policy and the User Agreement; we do not specifically provide services to, or actively collect personal information from, children under 14.
If we discover that we have collected personal information of a child under 14 without a guardian's consent, we will delete it as soon as possible.
7. Information Security
We adopt industry-standard measures: encrypted transmission (HTTPS/TLS), least-privilege access control in the cloud, and collecting only the minimum information necessary.
However, no security measure is 100% guaranteed. If a personal information security incident occurs, we will take remedial measures as required by law, notify you via push notification/in-app message, and report to regulators where necessary.
8. Updates to This Policy
We may revise this Policy from time to time. The revised version will be published in the App with an updated date; material changes affecting your rights will be highlighted via pop-ups or in-app notices. Continuing to use the App after an update means you accept the revised Policy.
9. Contact Us
If you have any questions, comments or complaints about this Policy or our handling of personal information, please contact us (please use "Twintrail Privacy Enquiry" as the email subject):
- Email: black.huaguofeng@foxmail.com (any update after release will be announced in the App);
- or use the feedback channel in the "Mine" menu. We will reply within 15 working days of receipt.
