HistoryCalc is an iPhone calculator with an on-device history tape and a discount helper. There is no cloud account for your calculations.
Common questions
- History disappeared after reinstall. Tape is stored only on this iPhone. Uninstalling removes it. We cannot restore it from the cloud.
- Unlock / restore. Settings → Restore Purchase (use the same Apple ID that bought the one-time unlock). Sign in with Apple is only for buying or restoring.
- Save to Photos was denied. iPhone Settings → HistoryCalc → Photos → Add Photos Only (or Allow).
- Delete sign-in. Settings → Account in the app.

技术支持
HistoryCalc 是 iPhone 计算器：本机纸带 + 折扣快算。计算记录没有云账号。
常见问题
- 重装后历史没了。 纸带只存在这台 iPhone。卸载即删除，我们无法从云端找回。
- 解锁 / 恢复。 设置 → 恢复购买（使用当时买断的同一个 Apple ID）。通过 Apple 登录只用于购买或恢复。
- 无法存到相册。 系统设置 → HistoryCalc → 照片 → 添加照片（或允许）。
- 删除登录。 应用内 设置 → 账号。
