Privacy Policy
This policy covers the Cullpack iPhone app (shown as 交片 on Chinese-language phones) and the website patelinasol.com. Both are run by Patelina Solution LLC ("we").
Summary
Cullpack does not collect any data. Your photos, and the face data the app works out from them, stay on your device and on the storage you chose. Nothing is sent to us. Photos go to another device only when you choose to let someone pick their own, and then they go straight to that person's device.
The Cullpack app
What we collect
Nothing. The app makes no network request. It has no account, no analytics, no advertising and no third-party code. We cannot see your photos or anything you do in the app.
Photos
The app reads the photos and videos in the folder you choose. They leave their place only through your own actions:
- Swiping to discard, and clean-up, move files into a
_to_deletefolder inside the same folder. - Export copies files to the location you choose.
The app does not delete photos. When you repeat an export, it removes only copies that it exported itself earlier and that are no longer wanted.
Face data
To group photos by person, the app works out face and body-appearance features from your photos. This happens on the phone, using models built into the app. These features are biometric data.
Nothing is analysed until you have agreed. Before the first analysis the app shows a notice that says what is computed, where it is stored and how to clear it. If you agree, the app analyses the photos in each folder you open, by itself if the switch on the start screen is on, or when you tap to analyse. If you choose "Not now", nothing is analysed.
- They are stored only in a file named
.swipe_clean_faces.npzin the photo folder, next to the photos. If the folder is on an SD card or an external drive, the file travels with it. - Group names and your corrections are stored in
.swipe_clean_people.jsonin the same folder. - They are not uploaded, not shared, and not used to identify anyone outside that folder.
You are responsible for having the right to process photos of the people in them. Group and share photos of people only when you are entitled to.
How long face data is kept
The face data stays in the photo folder until you clear it there or delete the files yourself. We have no copy, so there is nothing for us to keep or delete. Your agreement to the notice is stored in the app's own settings and is removed when you delete the app.
Deleting face data
On the people screen, open the "…" menu and choose "Clear face data…". This deletes .swipe_clean_faces.npz, .swipe_clean_people.json and the face thumbnails cached for that folder. Your photos are not touched.
Letting someone pick their own photos
The app accepts connections from other devices in one case only: while you have turned on "Let them pick" for a person and the app is open on screen. It then listens on the local network (Wi-Fi or this iPhone's Personal Hotspot, never the cellular connection), so that person can open a private link in their own browser.
- The link carries a random token. With it, a browser can see that person's photos as previews, mark each one to keep or drop, submit, and afterwards download the photos they kept. The previews are re-encoded copies without location or camera data, and file names are not shown. Nothing else is served.
- The photos go directly from your iPhone to their device. They do not pass through us or through any server.
- Anyone on the same network who has the link can open it, so give it only to the person it is for.
- The app stops accepting connections when you pause or stop sharing, close the folder, or leave the app. It does not start again by itself.
- Their choices are stored in
.swipe_clean_guests.jsonin the photo folder. "Stop sharing" makes the link stop working and clears their choices.
What the app keeps on the phone
In its own storage the app keeps the last photo folder and the last export location, your "Include subfolders" and order options, and small face thumbnails for the people cards. Deleting the app removes all of these.
In the photo folder it also keeps your progress in .swipe_clean.json, and a record of what was exported in .swipe_clean_export.json in the export location.
Tracking
The app does not track you and does not link any data to you.
