Privacy Policy
This policy describes how the iPhone app HistoryCalc (bundle ID com.historycalc.historycalc) handles information. HistoryCalc is a calculator with an on-device history tape. It is not an account-based cloud service.
What stays on your iPhone
Calculation history, notes, favorites, language, and keypad preferences are stored only on your device. We do not sync this tape to our servers, and we do not operate a HistoryCalc cloud account for your calculations.
You can delete a single tape row, or clear all local history, in the app.
What we do not do
- No advertising SDK, no analytics SDK, no crash-reporting SDK in this version.
- No tracking across other companies’ apps or websites.
- No selling of personal data.
- We do not read your photo library in the background.
Sign in with Apple and purchases
You can calculate without an account. Sign in with Apple is used only when you buy or restore the one-time unlock.
If you sign in, Apple may provide a user identifier (and, on first authorization, an email). HistoryCalc stores the Apple user identifier in the iOS Keychain on this device so we can show signed-in state and offer account deletion. Purchase status is provided by Apple’s App Store / StoreKit. We never see your Apple ID password or payment card number.
Network access is used for Sign in with Apple, in-app purchase, and restore. Calculating, browsing the tape, discounts, and generating a share image work offline.
Photos
If you choose Save to Photos, the app writes an image you just created. That uses Apple’s add-only Photos permission. We do not upload photos.
Third parties
The only third party involved in these flows is Apple (Sign in with Apple, App Store, StoreKit, and the Photos app on your device). Their handling of data is governed by Apple’s policies.
Children
HistoryCalc is a general calculator tool (age rating 4+). It is not directed at children under 13, and it does not knowingly collect personal information from children.
Your choices
- Clear or delete tape rows in the app at any time.
- If you signed in, Settings → Account lets you remove the Apple sign-in on this device (and optionally delete local history).
- You can deny Photos permission; saving to the library will then be unavailable.
- Uninstalling the app removes local HistoryCalc data on that iPhone.
Changes
If this policy changes in a material way, we will update the date on this page. Continued use after an update means you accept the revised policy.

隐私政策
本政策说明 iPhone 应用 HistoryCalc（Bundle ID com.historycalc.historycalc）如何处理信息。HistoryCalc 是带本机纸带的计算器，不是云端账号服务。
只保存在你这台 iPhone 上的内容
计算历史、备注、收藏、语言和键盘偏好只存在本机。我们不会把纸带同步到自己的服务器，也不为计算记录提供 HistoryCalc 云账号。你可以在应用里删除单条或清空全部本地历史。
我们不会做的事
- 本版本没有广告 SDK、分析 SDK、崩溃上报 SDK。
- 不做跨应用/网站追踪。
- 不出售个人数据。
- 不会在后台读取你的相册。
通过 Apple 登录与购买
算数不必登录。只有购买或恢复一次性解锁时，才会用到通过 Apple 登录。
如果你登录，Apple 可能提供用户标识（首次授权时还可能提供邮箱）。HistoryCalc 把 Apple 用户标识存在本机钥匙串，用于显示登录状态和提供删除账号。购买状态由 App Store / StoreKit 提供。我们看不到你的 Apple ID 密码或银行卡号。
需要联网的只有：登录、购买、恢复购买。计算、浏览纸带、折扣和生成分享图可以离线使用。
照片
只有你选择「存到相册」时，应用才会把刚生成的图片写入相册（系统「仅添加」权限）。我们不会上传照片。
第三方
上述流程里涉及的第三方只有 Apple（通过 Apple 登录、App Store、StoreKit，以及本机照片 App）。Apple 如何处理数据以其政策为准。
儿童
HistoryCalc 是通用计算器（年龄分级 4+），并非面向 13 岁以下儿童，也不会故意收集儿童的个人信息。
你的选择
- 可随时在应用里删除或清空纸带。
- 若已登录：设置 → 账号 可移除本机的 Apple 登录（也可同时删除本地历史）。
- 可拒绝相册权限，之后将无法存到相册。
- 卸载应用会删除这台 iPhone 上的 HistoryCalc 本地数据。
变更
若政策有实质更新，我们会修改本页日期。更新后继续使用即表示你接受修订后的政策。
