Prunedeck ("the app") helps you tidy the photos and videos on your Android phone by swiping through them one at a time. Everything happens on your device. TanzSoft does not collect, store, transmit, sell or share any personal data.
The app asks for access to your photos and videos (READ_MEDIA_IMAGES / READ_MEDIA_VIDEO, or storage read access on older Android versions) because its core function is to show every item in your gallery so you can decide to keep or remove it. On Android 14 and newer you may grant access to selected photos only; the app then works with just those.
The app reads file information (date, size, album name, dimensions) and image pixels on your device to display photos, group them into piles (by month, album, screenshots, videos, large files) and to compare similar photos (a small shape fingerprint and a sharpness score are computed in memory). None of this leaves your device.
Swiping never deletes anything. Items you toss are listed in the app's bin until you confirm. On Android 11 and newer, confirmed items are moved to the system trash through Android's own confirmation dialog, where they can be restored for about 30 days; you can also empty the trash from the app. On Android 8–10 there is no system trash, so confirmed items are deleted permanently — the app says so before you confirm. "Favorite" uses Android's own favorite flag on Android 11 and newer, again with Android's confirmation dialog.
The app keeps a small local database on your device: your keep/toss/favorite/later decisions (by media ID), daily counts for your goal and streak, and the list of items you moved to the trash (ID and size). It is excluded from cloud backup. Uninstalling the app removes it.
If you tap "Share result", the app creates an image containing only numbers (space freed, item count, streak) — no photos — and hands it to the Android share sheet. It is sent only where you choose.
The app is not directed at children and collects no data from anyone.

Prunedeck 는 휴대폰 안의 사진·동영상을 한 장씩 넘기며 정리하는 앱입니다. 모든 처리는 기기 안에서만 이뤄지며, 탄즈소프트는 개인정보를 수집·저장·전송·공유하지 않습니다. 앱에는 인터넷 권한이 없고 계정·분석·광고 SDK 가 없습니다. 사진·동영상 접근 권한은 갤러리 전체를 보여 주고 정리하기 위한 핵심 기능에만 씁니다(안드로이드 14 이상은 일부 사진만 허용 가능). 넘기기만으로는 아무것도 지워지지 않으며, 확인을 누른 항목만 안드로이드 11 이상에서 시스템 휴지통(약 30일 복구 가능)으로 옮겨집니다. 안드로이드 8~10 은 휴지통이 없어 바로 삭제되며 앱이 미리 알립니다. 결정 기록·하루 정리 수는 기기 안 작은 데이터베이스에만 저장되며 앱을 지우면 함께 지워집니다. 문의: tanzsoftkor@gmail.com
