Privacy Policy
Last updated 20 October 2026
Nightwalk collects nothing. There is no analytics SDK, no advertising SDK, no crash reporter, no account system and no network code in the app at all.
What the app stores
Everything Nightwalk remembers is written to your device's local application storage
(UserDefaults) and never leaves it:
- your session log — for each finished session, the date, minutes focused, depth reached, spoils, ember and whether the expedition returned
- your party roster and its ranks
- your ember balance and total focused time
- your preferred session length
- the descent in progress, if any — its depth, the sessions walked and the spoils it is carrying
- your reminder settings — whether each reminder is on, and the time you chose
This matches the app's privacy manifest, which declares exactly one accessed API category:
UserDefaults, for reason CA92.1 — data accessible only to the app itself.
Deleting the app deletes all of it.
Reminders and the Lock Screen
Reminders are off until you turn them on. If you do, Nightwalk asks for the standard iOS notification permission and schedules local notifications on your device. They are created on the phone and delivered by iOS; they never pass through a server, and the app does not use push notifications, so no device token is created or sent anywhere. You can turn them off in the app or in iOS Settings at any time.
During a session, the Live Activity on the Lock Screen and in the Dynamic Island is drawn by iOS from what the app hands it on the device — the time left, the current depth and the session number. Nothing about it leaves your phone, and it is cleared shortly after the session ends.
What the app does not do
Nightwalk does not use the camera, microphone, photo library, contacts, calendar, location, health data or motion sensors. It does not read which other apps you have or use. The session timer works entirely from the clock and from whether Nightwalk itself is in the foreground — it cannot see what you do in other apps, only that you left this one.
What we receive
Nothing. We have no server, and the app makes no network requests. If you email us for support, we will of course have whatever you choose to put in that email; we use it only to answer you and we do not add you to any list.
Children
The app collects no personal data from anyone, including children under 13. There is no advertising and no third-party content.
Third parties
The app bundles no third-party SDKs. Apple may collect standard App Store information when you download or update the app; that is governed by Apple's privacy policy, not ours.
Changes
If this policy ever changes, the updated version will be posted on this page with a new date.

개인정보 처리방침 (한국어)
나이트워크는 어떤 개인정보도 수집하지 않습니다. 분석 도구, 광고 SDK, 크래시 리포터, 계정 시스템이 전혀 없으며, 앱에 네트워크 통신 코드 자체가 없습니다.
세션 기록(날짜·집중 시간·도달 깊이·전리품·잉걸·귀환 여부), 원정대 구성과 등급, 잉걸 잔액, 총 집중 시간, 선호 세션 길이, 진행 중인 원정(깊이·걸어온 세션·들고 있는 전리품), 알림 설정(켜짐 여부와 시각)은 모두 기기 내부 저장소에만 기록되며 외부로 전송되지 않습니다. 앱을 삭제하면 함께 삭제됩니다.
알림은 직접 켜기 전까지 꺼져 있습니다. 켜면 iOS 표준 알림 권한을 요청하고, 알림은 기기 안에서 예약되는 로컬 알림으로만 전달됩니다. 서버를 거치지 않으며 푸시 알림을 쓰지 않으므로 기기 토큰도 만들거나 보내지 않습니다. 세션 중 잠금 화면과 다이내믹 아일랜드에 보이는 라이브 액티비티는 앱이 기기 안에서 넘겨준 정보(남은 시간·현재 깊이·세션 번호)로 iOS가 그리며, 폰 밖으로 나가지 않고 세션이 끝나면 곧 사라집니다.
카메라·마이크·사진·연락처·캘린더·위치·건강·모션 데이터를 사용하지 않습니다. 다른 앱의 사용 내역을 볼 수 없고, 세션 타이머는 시계와 나이트워크가 전면에 있는지 여부만으로 동작합니다. 광고와 제3자 콘텐츠는 없습니다.
