This page describes what Pet Check (the “App”) stores on your device and what it sends off the device, exactly as the App is built.
The short version
- What you record (your pet’s photos and observation notes) is stored on your iPhone. It is not sent to our servers.
- Usage records — that the App was opened and closed, and that you tapped one of the two buttons in Settings — are sent automatically from the moment the App launches. The current version has no switch to turn this off.
- Those usage records are stored on a server located in India (Mumbai), operated through Supabase Inc. (USA).
1. What is stored on your device
Pet profiles (name, species, breed, birthday), the spots you watch (label and body part), the photos themselves (stored as JPEG files in the App’s own folder), each photo’s time, concern level and note, the text produced when two photos are compared, and settings such as text size. There is no account and no sign-in.
This stays inside the App’s storage area on your iPhone. It is not sent to our servers.
2. What is sent off the device (usage records)
The App sends usage records from the moment it launches. These are the fields it sends:
- An anonymous ID (a string generated per device; it is not linked to your name or email address)
- A session ID, the app ID (ltd.nextcode.petspotwatcher), and the app version
- The iOS version, the device type (“iPhone”), and the device language setting
- That the App was opened and closed, and how long it stayed open
- That you tapped “Rate this app” or “Send feedback” in Settings
Sending starts automatically at launch and happens roughly every 30 seconds, or in one batch when you close the App. Per-screen records — which screen you viewed and for how long — are not sent in this version. The current version has no setting to stop it. If you want it to stop, delete the App.
3. What is not sent
- The photos you take and anything you type (pet names, notes, comparison results)
- Your name, email address, postal address, phone number, or date of birth
- Location, contacts, calendar, or the contents of your photo library
- The advertising identifier (IDFA). The App does not ask for tracking permission and shows no ads.
4. Where the data goes
The usage records above are stored in a database we operate on Supabase (Supabase Inc., USA). The server running that database is located in India (Mumbai). We state this plainly because the data leaves Japan.
We use these records only to investigate and fix problems in the App. We do not sell or share them with third parties.
5. How the comparison text is produced
The text you see when two photos are compared is assembled on your iPhone. Code for sending photos to a server for analysis is still present in the App, but this version does not carry the settings needed to connect, so photos never leave the device. The vet report is also produced on the device; whether you send it to anyone is your own action.
6. Camera and photos
The camera is used when you photograph a spot, and the photo library only when you import an older picture. Imported photos are saved in the App’s own folder and are not sent anywhere. The App does not read your whole photo library.
7. Purchases
Purchases and payments are handled by Apple’s App Store (StoreKit). Card numbers and other payment details are never passed to the App. The App only sees whether a purchase is active.
8. Notifications
Notifications are built and shown entirely on your device. There is no push server, and notification content never leaves the device.
9. Retention and deletion
- “Delete everything” in Settings removes pets, spots, the photo files and the comparison results together.
- Deleting the App deletes the data on your device. Deleted data cannot be restored.
- Usage records already sent remain attached to the anonymous ID. The App has no screen that displays that ID, so you cannot match it yourself. If you want them deleted, contact info@usmc.jp.
- If you use an iPhone backup (iCloud backup or a computer backup), the App’s data is included in that backup.
10. Sending feedback
Tapping “Send feedback” in Settings opens the iPhone Mail app with a message addressed to info@119.bz. Sending it is your own action. If you send it, we receive what you wrote and the email address you sent it from.
11. Children
The App is intended for users aged 13 and over.
12. Updates to this page
When we change the App, we update this page. If a future version sends more than what is listed here, we will update this page before that version ships.
