先读这一段。姨妈记是个人健康记录工具，不是医疗器械， 不能用于诊断或治疗，也不能作为避孕方法。如果你出现大量出血、剧烈疼痛、晕厥、 胸痛、呼吸困难或突然无力，请立即就医，不要等 App 告诉你什么。
1. 姨妈记是什么
姨妈记（Yimaji）记录你的经期、症状、基础体温、疗法与备注，并依据这些记录给出周期预测、 易孕窗口与趋势洞察。它不要求注册，没有账号，数据留在你的设备上。
- iPhone 与 iPad，iOS 18 或更新版本；
- Apple Watch App 与表盘复杂功能，watchOS 11 或更新版本；
- 主屏幕与锁屏小组件；
- 界面支持 10 种语言：简体中文、繁體中文、English、日本語、한국어、Español、 Français、Deutsch、Português (Brasil)、العربية（从右到左）；
- 日期始终按公历显示，数字格式随你的地区设置变化。
2. 第一次打开
没有登录，也不需要账号。设置向导只问几件事：
- 目标模式：记录周期、备孕、怀孕或围绝经期。它决定首页强调什么、 显示哪些洞察，随时可以在「设置」里更改。
- 上一次经期的开始日，以及典型的周期长度与经期长度。不确定就填大约值， 之后记录多了，预测会自己校准。
- 提醒（可选）：经期提醒、每日打卡与用药提醒。通知权限只在你要开提醒时才会请求。
- Apple 健康同步（可选，默认关闭）。
3. 怎么记录
同一条记录可以有几种入口，写进去的是同一份数据：
- 日历：点某一天打开记录页，补记过去的日子也可以。
- 「今天」页：当天状态、快捷按钮与下一次经期。
- 小组件：点一下进入记录；Pro 的大号小组件可以直接开始今天的经期。
- Apple Watch（Pro）：在手腕上开始经期、查看下一次经期；手表上的记录会同步回手机。
- Siri 与快捷指令（Pro）：例如「开始经期」「下一次经期是什么时候」。
一天里可以记录：流量、症状及其程度、心情、精力、基础体温、宫颈黏液、排卵测试、 验孕结果、性生活及是否防护、疗法打卡、自定义症状标签（Pro）和备注。 记录页只显示你打开的项目，可以在「设置」里调整；不想记的项留着空白就行。
4. 免费与 Pro

付费墙上写明了时长、结束后哪些功能停止，以及全程不产生费用。
6. 预测与洞察
预测完全基于你自己记录的历史：
- 下一次经期显示为一段范围，而不是一个精确的日子；记录越多，范围通常越窄。
- 周期不规律时，范围会变宽——这是有意为之，把不确定如实画出来，而不是假装精确。
- 易孕窗口与排卵日都是估算，不能用于避孕，也不能替代医生的判断。
- 免费版提供最近三次周期的统计；Pro 提供完整历史、逐个周期的统计，以及按周期阶段、 同期出现的症状、与过去相比的变化、疗法打卡与其他日子的对比。
7. 就诊摘要与 PDF 报告
免费版可以生成一份覆盖最近六个周期、列出记录最多的八种症状的就诊摘要，适合带去门诊。 Pro 的报告构建器可以选择时间范围与要包含的章节，生成多页 PDF，在本机渲染， 通过分享面板发送、打印或存到「文件」。报告只在你点分享时离开 App。
8. Apple 健康
同步默认关闭。打开后：
- 姨妈记把你亲手输入的值写入「健康」（月经流量、基础体温、宫颈黏液、排卵与验孕结果、 性生活，以及腹痛、头痛、疲劳等症状），从不写入预测；
- 同时读取你在「健康」里记录的同类数据并合并进来，每条写入带同步标识，不会重复；
- 在姨妈记里删除自己写入的记录，会删除对应的健康样本；其他来源的样本不受影响；
- 权限随时可以在 iOS「设置 › 健康 › 数据访问与设备 › 姨妈记」里关闭；
- 删除 App 不会删除已写入「健康」的记录，那些要在健康 App 里单独删除。
9. 提醒
提醒分三类：经期提醒、每日打卡提醒、用药提醒。它们都是本机通知，由 iOS 在你设定的时间发出， 不经过服务器。Pro 可以把每日提醒加到最多八个时间点。如果提醒没有响，先检查：
- iOS「设置 › 通知 › 姨妈记」是否允许通知；
- 是否开着专注模式或低电量模式；
- App 内对应提醒是否仍然开启，时间是否被改过。
10. 小组件与 Apple Watch
小组件读取 App 写在本机的一份摘要快照（今天的状态、本周条带、下一次经期）。 长按主屏幕空白处 › 左上角「+」› 搜索「姨妈记」即可添加；锁屏小组件在锁屏编辑界面添加。 大号小组件与「开始今天的经期」按钮属于 Pro。
Apple Watch App 属于 Pro，提供四种表盘复杂功能，可以从手腕开始今天的经期。 手表显示的是手机同步过来的摘要；在手表上记录后，回到手机 App 时会合并进同一份记录。
11. 备份、恢复与导出
- 加密备份：在「设置 › 数据」里导出
.ymbk文件。它包含这台设备上的 全部记录，包括疗法名称与剂量，用你设置的通行短语加密（AES-GCM，密钥由 PBKDF2-HMAC-SHA256 派生）。通行短语不会被保存，忘了就无法恢复这份备份。 - 恢复：选择备份文件，输入通行短语，App 先校验再替换这台设备上的全部记录。 这个操作不可撤销，会要求你确认两次。
- CSV 导出：按天导出记录，便于自己分析或交给医生。
- 换新手机：姨妈记没有账号，也不会通过 iCloud 在设备之间同步。 在旧手机上导出一份加密备份，在新手机上恢复即可。
12. 隐私与安全
没有账号，没有服务端，没有广告，没有第三方分析；我们不会收集也不会收到你的记录。 打开应用锁后，每次冷启动由 iOS 验证面容 ID 或设备密码，姨妈记不接触任何生物识别数据。 完整说明见隐私政策。
13. 常见问题
预测的日子和实际差了好几天，正常吗？
正常。预测是对历史的统计估计，不是对身体的测量。周期长度会随压力、睡眠、旅行与 健康状况变化；记录越多，估计会越贴近你的规律。如果周期长期不规律，或经期明显推迟、 出血异常，请咨询医生。
经期已经推迟了，App 还显示「应该来了」？
App 只能根据已有记录推算。经期真的开始后，在日历上记下第一天，预测会立即重算。
怎么把数据换到新手机？
旧手机：「设置 › 数据」导出加密备份，记住通行短语，把文件用隔空投送或「文件」传过去； 新手机：安装姨妈记，在「设置 › 数据」里恢复。恢复会替换新手机上的全部记录。
重装 App 后 Pro 不见了？
用购买时的同一个 Apple 账户，在付费墙或「设置」里点「恢复购买」。Pro 是终身买断， 不会因为重装或换设备而失效。试用每个账户只能用一次，重装不会重置试用。
试用会自动变成付费吗？
不会。试用是一件 0 元的非消耗型商品，不是订阅，没有自动续订，结束时不会扣款。
开了 Apple 健康同步，为什么数据没有马上出现？
同步在 App 打开时进行。回到 App 等一两秒，或下拉刷新。「健康」里的数据量很大时， 首次导入会慢一些。如果仍然没有，检查「设置 › 健康 › 数据访问与设备」里姨妈记的读写权限。
提醒没有响？
见上面第 9 节：通知权限、专注模式、低电量模式，以及 App 内提醒是否开启。
小组件不更新？
iOS 决定小组件的刷新时机，打开一次 App 通常会立即刷新。低电量模式会减少刷新。 如果显示的是旧内容，先打开 App，再回到主屏幕看看。
忘了应用锁的密码？
姨妈记没有单独的密码：应用锁用的是 iOS 的面容 ID 或设备密码。设备密码由 iOS 管理与找回， App 无法绕过，也不会保存它。
怎么彻底删除数据？
「设置 › 数据 › 删除全部数据」会清空这台设备上的全部记录；删除 App 也会移除 App 内的数据。 已经写入 Apple 健康的记录要在健康 App 里单独删除。你导出到「文件」或分享出去的备份、CSV、 PDF 由你保管，需要自己删除。
姨妈记能当避孕方法吗？
不能。易孕窗口与排卵日都是估算，不能用于避孕，也不能替代医生的建议。
支持 Android 吗？
目前只有 iPhone、iPad 与 Apple Watch。iPhone 需要 iOS 18 或更新版本，Apple Watch 需要 watchOS 11 或更新版本。
界面语言和日期格式怎么改？
界面语言跟随系统：iOS「设置 › 通用 › 语言与地区」。日期始终按公历显示，数字与月份名称 跟随地区的格式。阿拉伯语界面会自动采用从右到左的布局。

Read this first. Yimaji is a personal wellness record, not a medical device. It cannot diagnose or treat anything, and it is not a method of contraception. If you have heavy bleeding, severe pain, fainting, chest pain, trouble breathing or sudden weakness, get medical care right away — do not wait for the app.
1. What Yimaji is
Yimaji records your periods, symptoms, basal body temperature, therapies and notes, and shows cycle predictions, a fertile window and trend insights based on them. No sign-up, no account, and your data stays on your device.
- iPhone and iPad, iOS 18 or later;
- an Apple Watch app with complications, watchOS 11 or later;
- Home Screen and Lock Screen widgets;
- the interface in 10 languages: English, 简体中文, 繁體中文, 日本語, 한국어, Español, Français, Deutsch, Português (Brasil), العربية (right to left);
- dates always shown in the Gregorian calendar, with numbers formatted for your region.
2. First launch
No sign-in and no account. Setup asks only a few things:
- Goal mode: tracking, trying to conceive, pregnancy or perimenopause. It decides what the home screen emphasises and which insights appear, and can be changed in Settings at any time.
- The first day of your last period, plus typical cycle and period lengths. Rough numbers are fine; predictions adjust as you log more.
- Reminders (optional): period, daily check-in and medication reminders. Notification permission is only requested when you turn a reminder on.
- Apple Health sync (optional, off by default).
3. How to log
There are several ways in, and they all write the same record:
- Calendar: tap a day to open its log, including days in the past.
- Today: today's state, quick actions and the next period.
- Widgets: tap to open the log; with Pro, the large widget can start today's period.
- Apple Watch (Pro): start a period and see the next one from your wrist; watch entries sync back to the phone.
- Siri and Shortcuts (Pro): for example “start my period” or “when is my next period”.
A day can hold flow, symptoms and their severity, mood, energy, basal body temperature, cervical mucus, ovulation test, pregnancy test, sexual activity and whether it was protected, therapy check-ins, custom symptom tags (Pro) and notes. The log shows only the rows you enable in Settings; leave anything you do not track blank.
4. Free and Pro
Logging, predictions and every privacy feature are free forever. Pro is a one-time $19.99 purchase that includes Family Sharing and all future updates.

| Siri and Shortcuts | — | ✓ |
| The Apple Watch app with four complication styles | — | ✓ |
| Every future update | ✓ | ✓ |
The free version never hides records you already wrote. When Pro ends, your records stay complete and readable.
5. The three-month free trial
The trial is a $0 non-consumable App Store product, not a subscription:
- it lasts three months from the day you confirm it;
- nothing is charged at the start, during it, or when it ends;
- there is no auto-renewal and nothing to cancel;
- it can be used once per Apple Account;
- after three months the Pro features above stop; your records stay, stay readable and can still be exported;
- buying Pro during or after the trial is a single purchase, with no double charge.
The paywall states how long it lasts, what stops afterwards, and that no money is involved at any point.
6. Predictions and insights
Predictions come only from the history you recorded:
- The next period is shown as a range, not an exact day; more records usually mean a narrower range.
- When cycles are irregular the range widens. That is deliberate: it shows the uncertainty honestly instead of pretending to be precise.
- The fertile window and ovulation day are estimates. They are not for contraception and do not replace a doctor's judgement.
- The free version gives statistics for the last three cycles. Pro adds your full history, per-cycle statistics, and insights by cycle phase, symptoms that appear together, what changed against your past, and therapy check-ins compared with your other logged days.
7. Visit summary and PDF reports
The free version builds a visit summary covering the last six cycles and the eight most-logged symptoms — useful to take to an appointment. Pro's report builder lets you choose the date range and the sections to include, producing a multi-page PDF rendered on the device and sent through the share sheet to print or save to Files. A report leaves the app only when you share it.
8. Apple Health
Sync is off by default. Once on:
- Yimaji writes the values you entered yourself into Health (menstrual flow, basal body temperature, cervical mucus, ovulation and pregnancy test results, sexual activity, and symptoms such as cramps, headache and fatigue). It never writes predictions;
- it also reads records of the same kinds from Health and merges them in; every write carries a sync identifier, so nothing is duplicated;
- deleting a record you made in Yimaji deletes the matching Health sample; samples from other sources are untouched;
- access can be revoked anytime in iOS Settings › Health › Data Access & Devices › Yimaji;
- deleting the app does not delete records already written to Health; delete those in the Health app.
9. Reminders
There are three kinds: period reminders, daily check-in reminders and medication reminders. All are local notifications delivered by iOS at the times you set, never through a server. With Pro you can add up to eight daily times. If a reminder does not arrive, check:
- iOS Settings › Notifications › Yimaji allows notifications;
- a Focus or Low Power Mode is not on;
- the reminder is still enabled in the app and its time has not changed.
10. Widgets and Apple Watch
Widgets read a summary snapshot the app writes on the device (today's state, the week strip and the next period). To add one, touch and hold the Home Screen › “+” in the top corner › search for Yimaji. Lock Screen widgets are added from the Lock Screen editor. The large widget and its “start today's period” button are part of Pro.
The Apple Watch app is part of Pro and offers four complication styles, and you can start today's period from your wrist. The watch shows the summary synced from the phone; entries you make on the watch are merged into the same record when you next open the app on the phone.
11. Backup, restore and export
- Encrypted backup: export a
.ymbkfile from Settings › Data. It holds everything on this device, including therapy names and doses, encrypted with a passphrase you set (AES-GCM, with the key derived by PBKDF2-HMAC-SHA256). The passphrase is not stored; without it the backup cannot be restored. - Restore: choose the file, enter the passphrase, and the app validates it before replacing every record on this device. This cannot be undone and asks you to confirm twice.
- CSV export: a day-by-day export for your own analysis or to hand to a clinician.
- Moving to a new phone: Yimaji has no account and does not sync between devices through iCloud. Export an encrypted backup on the old phone and restore it on the new one.
12. Privacy and security
No accounts, no server, no ads and no third-party analytics; we never collect or receive your records. With App Lock on, every cold launch is checked by iOS using Face ID or the device passcode, and Yimaji never touches biometric data. The full detail is in the privacy policy.
13. Frequently asked questions
My predicted date was off by several days. Is that normal?
Yes. A prediction is a statistical estimate from your history, not a measurement of your body. Cycle length shifts with stress, sleep, travel and health, and more records bring the estimate closer to your pattern. If your cycles stay irregular, or a period is clearly late or the bleeding is unusual, talk to a doctor.
My period is late but the app still says it is due?
The app can only extrapolate from what is recorded. Once the period actually starts, log its first day on the calendar and the prediction is recalculated immediately.
How do I move my data to a new phone?
On the old phone, export an encrypted backup from Settings › Data, note the passphrase, and send the file with AirDrop or Files. On the new phone, install Yimaji and restore it in Settings › Data. Restoring replaces everything on the new phone.
Pro disappeared after I reinstalled?
With the same Apple Account you bought it with, tap Restore Purchase in the paywall or in Settings. Pro is a lifetime purchase and survives reinstalls and new devices. A trial is once per account; reinstalling does not reset it.
Will the trial turn into a charge?
No. The trial is a $0 non-consumable product, not a subscription. There is no auto-renewal and nothing is charged when it ends.
I turned on Apple Health sync but nothing appeared yet?
Sync runs while the app is open. Return to the app and wait a second, or pull to refresh. The first import can be slower with a large Health history. If it still does not appear, check Yimaji's read and write access in Settings › Health › Data Access & Devices.
A reminder did not arrive?
See section 9: notification permission, Focus, Low Power Mode, and whether the reminder is enabled in the app.
A widget is not updating?
iOS decides when widgets refresh; opening the app usually refreshes one right away, and Low Power Mode reduces refreshes. If it still shows old content, open the app and return to the Home Screen.
I forgot my App Lock password?
Yimaji has no separate password. App Lock uses iOS Face ID or your device passcode, which iOS manages and recovers. The app cannot bypass it and never stores it.
How do I delete everything?
Settings › Data › Delete All Data clears every record on this device; deleting the app removes what is inside it too. Records already written to Apple Health must be deleted in the Health app. Backups, CSV files and PDFs you exported or shared are yours to keep and must be deleted by you.
Can Yimaji be used as contraception?
No. The fertile window and ovulation day are estimates. They are not a method of contraception and do not replace medical advice.
Is there an Android version?
Currently iPhone, iPad and Apple Watch only. The iPhone needs iOS 18 or later and the watch needs watchOS 11 or later.
How do I change the language or date format?
The interface follows the system language in iOS Settings › General › Language & Region. Dates are always Gregorian, with numbers and month names formatted for your region. The Arabic interface uses a right-to-left layout automatically.
A feature request, or something is wrong?
Write to us. The more specific the report — which screen, what you tapped, what you expected and what happened — the faster we can find it.
