Privacy Policy

1. Our approach

Hatara Kiroku exists so that working people can keep a record of their own working hours. Because that record belongs to the person who made it, the app is built on the following principles.

• Recorded data is stored only on the user's device.
• The app does not transmit recorded data to any server.
• There are no user accounts, and the app does not collect names or contact details.
• No advertising, analytics, or third-party tracking components are included.
• Location data is not collected beyond what is needed to measure working hours.

2. What the app collects

2-1. Location data

The app collects and stores the following location data on the device.

If no location is available at the moment a boundary crossing is detected, the app records the stored coordinates of the workplace instead. In that case, no accuracy value is recorded.

2-2. Information you enter

• The name of a workplace (assigned automatically at first, for example "勤務先1")
• A free-text note about the workplace (optional, for example "Head office, 3rd floor")
• Wage settings (hourly or monthly wage, standard monthly hours, contracted weekly hours, which weekday counts as the statutory day off, and how public holidays are treated)

These are stored on the device exactly as you enter them. The app does not look them up against any external service or transmit them anywhere.

2-3. Arrival and departure records

The app stores each event — that you entered or left a given workplace — along with the time it occurred, the time it was recorded, and how it was detected (automatic detection, a check performed when the app opened, or a manual entry).

Working hours themselves are not stored. They are calculated from these events each time they are displayed.

2-4. Diagnostic log

For troubleshooting purposes, the app keeps a diagnostic log on the device. Each entry contains a timestamp, a severity level, a category, and a message.

Message text may include latitude and longitude (to five decimal places), part of the internal identifier of a workplace, the workplace radius, and positioning accuracy. The log is also stored only on the device, and the app never transmits it automatically.

2-5. Other

Whether you have completed initial setup is stored in the device's app settings.

3. What the app does not collect

The app does not collect any of the following. There is no screen or mechanism in the app to do so.

• Name, email address, phone number, postal address, or date of birth
• Account credentials or passwords — the app has no registration or sign-in
• The name of your employer or details about them, except where you have typed them yourself as a workplace name or note
• Contacts, photos, calendars, microphone, camera, or health data
• Advertising identifiers (IDFA) or other device identifiers
• Routes, travel history, or a record of places you passed through
• Usage statistics, interaction history, or crash reports sent to anyone

4. How location data is used

4-1. Purpose

Location data is used solely to detect when you enter or leave a registered workplace and to calculate your working hours. It is not used for any other purpose.

4-2. How it is obtained

The app uses the geofencing (region monitoring) feature of iOS. It registers a circular region centred on each workplace with iOS, and iOS notifies the app when you cross the boundary.

The app does not track your location continuously. It reads your location only in these cases:

• When you tap to capture your current location while registering a workplace
• When iOS detects that you have crossed the boundary of a registered workplace
• When the app comes to the foreground and checks your position against the existing record

4-3. Background use

The app does use location data in the background. This is necessary to record arrivals and departures while the app is closed, which is why it asks for location access set to "Always".

What happens in the background is limited to detecting and recording boundary crossings at your workplace. The app does not follow your movements.

If location access is set to anything other than "Always", the app's behaviour is limited and its measurement of working hours becomes unreliable.

5. Where data is stored

All of the data described above is stored only on the user's device. The app has no server of its own, and it is not configured to store data in any cloud service. It does not sync via iCloud.

Note that if you have device backups enabled (iCloud Backup, or a backup to a computer), the operating system may include the app's data in that backup. This is a function of iOS, not data being transmitted by the app. Backup settings can be changed in the iOS Settings app.

6. Transmission and disclosure to third parties

The app does not transmit location data, workplace information, arrival and departure records, wage settings, or diagnostic logs to anywhere outside your device. The operator does not receive any of it.

The app contains no third-party components for advertising, analytics, behavioural tracking, or crash reporting.

Consequently, the app does not disclose user data to third parties.

Note that displaying a map relies on the operating system's map feature, which involves communication with Apple's services. See "7. Map display" for details.

7. Map display

When a map is shown — for example while registering a workplace — the app uses the standard iOS map framework (Apple's MapKit). The communication required to display the map takes place with Apple's services.

The app does not transmit data to any server of its own. It has no backend service.

For what information Apple handles in connection with MapKit, please refer to Apple's privacy policy.

8. Exporting the diagnostic log

The app can export the diagnostic log stored on your device as a text file. This happens only when you choose to do it, and where the exported file goes — or whether it goes anywhere at all — is your decision. The app never sends it automatically.

An exported file may contain location coordinates. Please review the contents before sharing it with anyone.

9. How long data is kept

Because work records exist precisely so that you can look back on them, the app does not erase them on its own.

10. How to delete your data

In the current iOS version, deletion works as follows.

11. Changing or withdrawing location permission

You can change or withdraw location permission at any time from the iOS Settings app.

Go to Settings > はたらきろく > Location to change the permission state.

If permission is set to anything other than "Always", or if it is denied, the app can no longer record arrivals and departures automatically, and measurement of working hours becomes unreliable. Records made before the change are not deleted.

12. Requests for access, correction, or deletion

Data recorded by the app exists only on the user's device; the operator neither receives nor holds it. The operator therefore cannot disclose, correct, or delete user data, and holds no such data to begin with.

You can review the contents of your records yourself, on your own device.

13. Use by children

The app is not designed for any particular age group and does not collect information about age. If a child uses the app, guardians are encouraged to review the location permission settings.

14. The Android version

This policy covers the Hatara Kiroku service as a whole. However, the iOS version is still in development and has not yet been released. The specifics described here reflect that iOS implementation.

An Android version is planned but is not available at this time. When one is released, this policy will be revised to reflect its implementation.

15. Changes to this policy

This policy may change as features are added or the implementation changes. Any revised version will be published on this page together with its last-updated date.

16. Contact and operator information

For enquiries about this policy, or about how the app handles personal and location data, please use the contact below.

The app is developed and operated by an individual.
