Privacy Policy

App: The Prosecutor's Seal (도장을 찍는 사람) · Effective date: October 9, 2026

1. Information we do not collect

The developer does not collect or receive any of the following:

• Name, email address, phone number, or other contact details
• Account or sign-in information (the app has no accounts)
• Location data
• Contacts, photos, camera, microphone, calendar, or other device data (the app requests none of these permissions; the only permission it ever asks for is notifications, and only after you say you want them)
• The advertising identifier (IDFA)
• Usage logs, gameplay statistics, or crash analytics
• Any text you type in the game, such as the prosecutor's name
• Your game progress or save data

Every image, font, and data file the game uses is bundled inside the app, and its audio is synthesized on the device, so the game works without the internet. The app contacts a server for two purposes only, the update check (section 2) and registering or removing news notifications (section 3), and both go to the developer's own server. No ad network or analytics tool is included. The app shell and the update and notification features are built with open-source software (Capacitor and its plugins), configured to send nothing to the servers of the people who make that software.

2. Game update checks

The app can receive small fixes (bug fixes, wording, touched-up art) without waiting for an App Store update. While you are online, the app asks the developer's server whether a newer version exists once the title screen appears. If there is one, it downloads the changed files and applies them the next time you open the app. Nothing changes or restarts in the middle of a game. The check happens once each time you open the app and, while the app stays open, at most once an hour after that. If an update is already waiting, the app asks once more just before applying it, to confirm that the update is still current.

The app sends the following to the server:

• Version information — the app version (for example 1.0), the version of the game data you currently have (for example 1.0.0), the operating system (iOS) and its version, and similar technical details
• An installation number — a random number generated by the update feature travels with the request. It is not a hardware identifier or the advertising identifier, and the server does not read, store, or log it. The number is kept on the device (in the keychain), so the same value is used again if you delete and reinstall the app.

Of these, the server reads only three values, the app version, the game data version, and the operating system, to pick the right update. It does not save the contents of the request to a database or file. The server program's own log keeps one line per request with the time, the requested path, the result, and the app version and game data version. Nothing that says whose request it was (the installation number, the IP address, and so on) is written to that log, and the log is deleted after the hosting provider's retention period (section 4). Your name, the prosecutor's name, your saves, your play history, and the advertising identifier are not part of the request.

There is no setting to turn the update check off. Without an internet connection the check does not happen and the app runs the version it shipped with. These updates change only what the game shows and contains. Any change to how information is handled, as described in this policy, is released through an App Store update, and this document is revised first.

3. News notifications

The app can send notifications with game news such as new cases, updates, and events. They are sent only if you ask for them.

• When it asks. Not at first launch. After you finish the first case and return to your office, the game asks once (in Korean) whether you want news notifications. That dialog also says that the notifications may include promotional information (event announcements, update promotion, and the like) and links to this policy. The iOS permission prompt appears only if you tap 받기 (Yes). If you tap 나중에 (Later), the game does not ask again. After that, the prompt appears only when you switch on 소식 알림 (News notifications) yourself in the game's Settings.
• They are optional. Nothing in the game is rewarded for turning notifications on, and every feature works the same if you never turn them on or turn them off.

If you turn notifications on, the developer's server keeps the following and nothing else:

• A device token for notifications — a string Apple issues for this app on this device. It works as the delivery address for notifications. It contains no name, phone number, or Apple Account, it is not the advertising identifier (IDFA), and no other app uses it.
• The kind of token — whether it comes from a development build or an App Store build
• The app version and game data version
• What you consented to — that you agreed to receive news notifications (which may include promotional information), and whether you also agreed to receive them at night
• Times — when you consented to news notifications (the time recorded by the device and the time the server received it), when the server received your consent to night-time delivery if you turned that on, when the token was registered or refreshed, and when a notification was first delivered to that token

Your IP address, device name and model, advertising identifier, name, contact details, saves, and play history are not part of this registration, and the server neither stores nor logs them. The token is not kept alongside anything that says who you are, so the developer cannot tell whose token is whose.

• What it is used for. Only to send the notifications you asked for, and to comply with the law on promotional messages (consent, night-time limits, opting out, and periodic confirmation of consent). It is not used for ad targeting or user analytics, and it is never sold or rented.
• How notifications reach you. They travel through the Apple Push Notification service (APNs). When a notification is sent, the developer's server passes the token and the notification's title and body to Apple. No other company's notification service, such as Google's Firebase, is used.
• How long it is kept. Until you turn notifications off. When you switch off news notifications in the game's Settings, the app asks the server to delete the token and the server deletes it, together with the consent record, at once. If you delete the app, Apple invalidates the token, and the server deletes it once Apple reports it as invalid during a later send. Apple's report may not come right away, so an unusable token can remain on the server until then.
• Labelling of promotional notifications. Notifications that count as promotional information, such as event announcements, begin their title with (광고), the label Korean law requires for advertising, and end with how to opt out. Opting out costs nothing.
• Night-time limit. Between 9 p.m. and 8 a.m. Korea time, no notifications are sent, promotional or not. They are sent during those hours only to people who have separately switched on 야간(21시~8시)에도 받기 (Also receive at night) in Settings. That setting starts switched off.
• Confirming consent. Every two years from the day you consented, you are asked again whether you want to keep receiving them.
• A notification that arrives while you are playing appears only as a brief notice inside the game. The device's notification banner and sound are not used, and the game is not paused or moved to another screen.

How to turn them off.

• Switch off 설정 → 소식 알림 in the game, either from Settings on the title screen or from Settings in the in-game menu. If you are online when you do this, the token on the server is deleted immediately.
• Turning them off in the device's Settings → Notifications → 도장을 찍는 사람 also stops notifications from appearing. That alone may leave the token on the server, so to remove the token as well, switch the setting off in the game too.

4. Where the server is, and access logs

The developer's server runs on infrastructure provided by Railway, a hosting company. Railway is a United States company, and the server itself runs on Railway's infrastructure in the United States (outside the Republic of Korea). The tokens and consent records described in section 3 are kept in this server's storage.

As with any internet connection, when the app checks for an update or registers or removes notifications, Railway's access logs record the IP address, time, requested path, and user agent (a string describing the app and operating system). According to Railway, these logs are kept for between 3 and 90 days depending on the plan and then deleted. The developer uses them only to check that the server is working, never to identify users or for advertising. This privacy policy and the support page are served from the same server, so the same access log is made when you open them in a browser.

The developer's server program does not store IP addresses and does not write them to its own logs. What its own log does keep is the time, path, and result of each request, plus the version numbers for an update check and the kind of token for a notification registration (never the token itself). Railway keeps that log for the same period as above and then deletes it. To keep update checks and notification registrations from being flooded, the program briefly counts requests per address in memory (using a scrambled value rather than the address itself); that count is never written to a file.

All communication between the app and the server is encrypted with HTTPS. The administrative function that sends notifications is locked with a secret known only to the developer.

5. What is stored on your device

Continuing a playthrough requires the following, and all of it is stored on your device (in the app's local storage):

• One autosave and three manual save slots — the prosecutor's name, gender, and background chosen when starting a game, the investigation record of the case in progress, the dispositions and verdicts so far, career gauges such as the performance rating, and the in-game date
• Settings — whether sound effects, music, larger text for documents and dialogue, the 30-second petty-case timer, and fast dialogue are on
• Notification settings — whether news notifications and night-time delivery are on, when you consented, whether you have already seen the notification prompt, and, if notifications are on, this device's notification token (it is erased from the device when you turn them off; if the deletion request has not yet reached the server, it is kept only until that request gets through, so the request can be sent again)
• Update records — downloaded game files, the version waiting to be applied at the next launch, any version skipped because it failed to start, and the update feature's installation number (section 2; kept in the keychain)

Of these, the only things that leave the device are the version information and installation number sent with an update check (section 2) and, if you turn notifications on, the notification token together with what you consented to and when (section 3). Your saves and game settings never leave your device. They are not sent to the developer, and the developer can neither read nor restore them.

The in-game save export turns a playthrough into text you can copy. Where you keep it and whom you send it to is your decision. The app takes no part in that, and exported data does not reach the developer on its own.

6. Sharing with third parties

The developer does not sell your information and does not pass it to ad networks, analytics providers, or data brokers. Information reaches only the two companies needed to run the service.

• Railway (United States, server hosting) — the access logs described in section 4 are recorded there, and the tokens and consent records from section 3 are kept on its infrastructure.
• Apple (United States, push notification service) — when a notification is sent, the token and the notification's title and body are passed to Apple. This applies only if you turned notifications on.

The app has no ads and no in-app purchases, so it never handles payment information.

7. Children's privacy

The game deals with criminal case files and is not directed at children. It is not listed in the App Store's Kids category.

The app does not ask your age, and the developer does not knowingly collect personal information from children under 14 (under 13 as defined by the U.S. Children's Online Privacy Protection Act). The only text fields are the prosecutor's name and the save-import box, and those values stay on the device. The information in section 3 is kept on the server only when news notifications have been turned on.

If your child has turned on news notifications in this app and you would rather they had not, switch them off in the game's Settings or write to the contact address below.

8. How to delete your data

• Saves and settings: delete the app. Removing it from your device erases the autosave, all three slots, the settings, and any downloaded update files. The game keeps its data nowhere else, so nothing remains. Only the update feature's installation number (section 2) stays in the device keychain, and that value is not stored on the developer's server or anywhere else.
• Saves: overwrite. Saving to a slot again replaces what was in it, and starting a new game replaces the autosave. The game has no separate button for clearing a save on its own.
• Notification token: turn notifications off. Switching off news notifications in the game's Settings deletes the token and consent record from the server. If you plan to delete the app, switch them off first. If you delete the app without doing so, the token can no longer receive anything, but it is removed from the server only when Apple reports it as invalid during a later send.
• Notification token: request deletion. If you have already deleted the app and cannot switch notifications off, write to collaboair@gmail.com. The token is not tied to a name or contact detail, so please include the date and approximate time you turned notifications on; the developer will find the token that matches that record, delete it, and reply with the result. Even if no match is found, the token of a deleted app is removed once Apple reports it as invalid during a later send, as described above.
• Access logs. The developer's server does not store the contents of update-check requests. The server program's own log (time, path, result, version numbers) and the hosting provider's access logs cannot be deleted selectively by the developer; they are removed after the retention period given in section 4.

Deleted game data cannot be recovered. No copy exists on the developer's side, so recovery is not possible. If you want to keep a record, export your save first.

9. Changes to this policy

If an app update changes how data is handled, this document will be revised and the effective date above updated. If a feature that involves personal data is added, it will be described here and announced with that update.

• October 9, 2026 — Revised during pre-release checks. At night (9 p.m. to 8 a.m.) notifications of any kind are now sent only to people who separately turned on night-time delivery. Also added: that the server keeps the time of night-time consent, what the server program's own log contains, that the notification prompt says promotional information may be included, and that a notification arriving during play is shown only inside the game.
• October 7, 2026 — Revised because the release version (1.0) includes update checks (section 2) and news notifications (section 3). The statements that the app "makes no network connections, has no server, and collects nothing" were replaced with what is actually true.
• October 2, 2026 — First policy, written for a build that did not use the internet. That build was never distributed.

10. Contact

Questions about this policy or the app, and requests to access or delete your information: collaboair@gmail.com.

Privacy contact — the privacy contact at CollaboAir Co.,Ltd., which provides this app, handles questions and complaints about personal information. Contact: collaboair@gmail.com

If you write in, your address and message sit in the developer's mailbox. That is not something the app collects; it is used only to answer you, it is not passed on to anyone, and messages are cleared once the exchange is over. The same applies to any exported save you send while reporting a bug.

In the app, tapping 개인정보처리방침 (Privacy Policy) in the game's Settings or in the news notification prompt opens this page in the device's browser. Usage questions are answered on the support page.
