Time Choice Privacy Policy
Applies to the iOS app “时择 / Time Choice” (Bundle ID: com.xiongjieyang.timechoice).
Summary
Time Choice collects nothing. Everything you enter stays on your own iPhone. The app does not upload that data to the developer, has no account, no ads, and no third-party SDKs. The optional Pro subscription is billed by Apple.
1. Data the app processes
To perform calculations you enter the following, and it is stored only in the app's sandbox on this device:
| What you enter | Example | Purpose |
|---|---|---|
| Time ledger | Monthly take-home income, normal working hours, overtime, commute, work-related out-of-pocket expenses | Calculate your real hourly rate |
| Time-price settings | Decision basis, target multiplier, or a directly set amount | Set the time price used in decisions |
| Task details | Task name, your hours and material cost, the quote, coordination time, this task's budget, and whether to keep the experience or not delegate it | Calculate the recommendation for this task |
| Decision records | Snapshots of the above, results, save time, and what the released time is for | Let you review the estimate later in “Records” |
| Price-into-time input | Optional item name, price, standard-day hours | Convert a price into time |
| Common-item preferences | Which items to show and the unit price for each | Remember the items you use often |
The item switches and unit prices are local preferences, not a purchase history: the app does not store what you calculated or bought.
None of this is sent to the developer's servers. Subscription payment and renewal go through Apple's StoreKit; the app does not receive card numbers.
1.1 Logs
The app writes no income, task, quote or record data to system logs and performs no crash reporting or analytics.
2. What we do not collect
- No account, password or phone number (the app has no login or account system).
- No name, email address, or postal address.
- No location, contacts, photos, microphone, camera or health data, and the app requests no system permissions.
- No device identifiers (no IDFA / IDFV for tracking or advertising).
- No usage analytics, page tracking, search history or diagnostics.
- No third-party SDKs: the app has no third-party dependencies at all.
3. Storage and protection
Data lives in a local database (SwiftData) inside the iOS app sandbox.
The database file uses iOS file protection (available after first unlock), so it is protected while the device is locked. We do not implement additional end-to-end encryption and make no such claim; supporting it would require a separate key-management design.
We hold no copy of your data, so we cannot read, recover or delete it.
3.1 System backups
If you enable iCloud or computer (iTunes/Finder) backups for this device, iOS may include the app sandbox in that backup. Whether it does is determined by your system settings and Apple's policies; we cannot access those backups and cannot prevent them. To remove data entirely, delete it in the app (see §4) or turn that backup off.
4. Deleting your data
All deletion is in-app and requires no contact with us:
| What to delete | How |
|---|---|
| One decision record | “Records” → “Delete” on that row → confirm |
| All decision records | “Records” → “Clear” → confirm |
| Time ledger | “My hourly rate” → “Clear” → confirm |
| Everything | Uninstall the app; iOS removes its sandbox with it |
Deleted data cannot be recovered (we keep no copy; historical copies inside device backups follow your choice in §3.1).
5. What we never do
- We do not sell, rent or share your data with anyone.
- We do not use it for advertising, profiling or recommendations.
- We do not change the purposes described here without telling you.
6. Children
The app is intended for a general audience, is not directed at children, and collects no information from anyone. Because the app collects no data, there is no special processing for children.
7. Payments
The download is free. The home-screen card is an optional Pro subscription; Apple handles payment, renewal and receipts. This app does not receive or store card numbers or billing addresses, and it has no ads. The ledger and records stay on the device.
8. Third-party content
The “Principles” page contains a short English quotation with links to its sources (nav.al and navalmanack.com). Those sites open only if you tap a link, in your system browser; their policies apply. The app itself never requests them.
9. Changes
If a future version changes how data is handled (for example, adding sync), we will update this policy and its version and effective date, and note it in the App Store release notes. Since we hold no contact details, the App Store listing is the authoritative copy.
10. Contact
For privacy questions, use the App Support link on the 时择 App Store page. The app collects no contact details, so that is our only public contact channel.
