這個 app 不收集你的資料。記錄只存在你自己的手機裡，沒有帳號、沒有後端資料庫、沒有第三方追蹤。生理期是健康敏感資訊，本 app 的設計原則就是讓它不離開你的手機——除非你自己主動按下分享。
付款透過 Google Play Billing 處理，金流與付款資訊由 Google 經手，我們拿不到也不儲存你的卡號或付款細節。我們這端只記錄「已解鎖」這個布林值。

This app stores all data (period logs, cycle settings, share count) locally on your device via localStorage. There is no account system, no backend database, no analytics, and no third-party tracking SDKs.
When you generate a share link, the relevant dates and message are encoded into the URL itself. The recipient's page and the /ics calendar endpoint compute the calendar content on the fly and do not log or persist request contents.
Payments (for unlocking unlimited shares) are handled entirely by Google Play Billing; we do not receive or store payment card details, only a local "unlocked" flag.
Menstrual cycle data is sensitive health information. This app is deliberately designed so that data does not leave your device unless you actively choose to share it.
