Privacy Policy · Baby Tracker Pro

CloudEx Inc. ("we", "us", or "our") operates the "Baby Tracker Pro" app (the "Service"). This Privacy Policy explains what information the Service handles, how it is used, and the choices available to you. By using the Service, you are deemed to have agreed to the practices described in this Policy.

1. Our Core Principle

Baby Tracker Pro is an Android app for parents to log their baby's feeding, diapers, sleep, height and weight, and more, and to play soothing sounds at bedtime. Your child's information and records are all stored on your device. There is no account and no sign-in, and we do not operate any server that receives your records. We never view, collect, upload, or transmit your records to our servers. Specifically, we do not have access to any of the following:

Your child's name, date of birth, sex, due date, photos, and similar details
Records of breastfeeding, bottles, pumping, solids, diapers (stool color and consistency), sleep, temperature, medicine, vaccinations, doctor visits, symptoms, firsts, diary entries, and more, as well as height, weight, and head circumference
Album photos and the voices you record in "Your voice"
Files of records you exchange with your family

Your records leave your device only through actions you take yourself (sending records to family, exporting to a file, or sharing a photo) and through Android's own backup if you have turned it on in your device settings (Section 3.2).

2. How Your Child's Records, Photos, and Voices Are Handled

Health-related information: Records of feeding, diapers, sleep, temperature, medicine, vaccinations, doctor visits, symptoms, height and weight, and the like include information about your child's health. It is used only on your device to show your records, charts, the growth chart, and reminders. It is never sent to us or to third parties, and it is never used for advertising.
Sharing records with family: "Send records to family" bundles your records into a single file (.json) and sends it with an app you choose (a messaging app, email, and so on). You choose the recipient, and the file never passes through our servers. Album photos and recorded voices are not included. The person who receives it imports the file into the app ("Receive records from family"). Because the file contains records that include health-related information, please check the recipient carefully. How the file is handled by the app you use to send it is governed by that app provider's policy.
Photos: To take a photo, the app asks your device's camera app to take it; the app itself has no camera permission. To choose a photo from your device, the app uses Android's photo picker, so it has no storage permission either and receives only the photos you pick. Photos are saved as JPEGs no larger than 1600 px on the long side, in the app's own storage on your device. They are shared or exported only when you do so. When you tap "Save" on a milestone card, the card is saved to your device's photos (a folder with the app's name inside the Pictures folder, on Android 10 and later), where other apps that you have allowed to access your photos can also see it.
Microphone (Premium "Your voice"): The microphone is used only while you are recording on the voice recording screen, and permission is requested only when you open that screen. Recorded voices are stored only on your device and are never sent. They are not included in Android's backup, in the backup files you export from the app, or in the files you send to family.
Soothing sounds: Womb sounds, white noise, lullabies, and the other sounds are generated and played on your device. No audio is sent or received. A foreground service (media playback) is used so that the sounds keep playing with the screen off, and a notification is shown while they play.
Reminders: Feeding and diaper interval reminders, next nap window reminders, daily reminders, and running timers are scheduled and shown on your device. No information is sent anywhere to show them.
App lock: App lock is unlocked with your device's screen lock (fingerprint, face unlock, PIN, and so on). Android performs the check, and the app never receives biometric information such as your fingerprint or face.
Exports: Backup files (JSON, or ZIP with photos), CSV files, and PDF reports are written only to the place you choose. Please manage the storage and sharing of exported files yourself.

3. Information We Collect

3.1 Information Collected Automatically

Anonymous crash reports: Via Firebase Crashlytics. When the app crashes, we collect anonymous technical information such as the device model, OS version, app version, and error details. This does not include your child's information or your records, photos, or voices.
Purchase information: We use Google Play's purchase information to verify your one-time "Premium" purchase. We never receive any payment information such as credit card numbers.
List of our other apps: To show our other apps, the app downloads their names, descriptions, and icons from our content server (static files hosted on Cloudflare Pages). The request contains no personal data from the app. As with any request to a web server, the server receives your device's IP address as part of the connection.
Viewing this policy: When you open the privacy policy in the app, this page (https://babytrackerpro.cloud-ex.biz/privacy/) is shown inside the app. If it cannot be opened, a summary bundled with the app is shown instead. As with viewing any web page, the web server receives your device's IP address and similar connection information when this page is shown.

3.2 Information Stored on Your Device

Your child's information and records: Name, date of birth, sex, due date, marker color, and photos, together with records of breastfeeding, bottles, pumping, solids, diapers (stool color and consistency), sleep, temperature, medicine, vaccinations, doctor visits, symptoms, firsts, diary entries, and more, as well as height, weight, and head circumference, are stored in the app's storage on your device.
Album photos and recorded voices: Stored in the app's own storage on your device, as described in Section 2.
App settings: Display, reminder, and other settings are stored on your device.
The app's daily automatic backup: Once on each day you open the app, it automatically creates a backup of your records on your device and keeps the latest 7.
Recently deleted: Records you delete are kept in "Recently deleted" for 30 days and then deleted automatically. You can empty it at any time before then.
Android backup: If backup is turned on in your device settings, Android includes the app's records and settings in the backup it saves to your own Google account. This backup is handled by Google, and we have no access to its contents. Photos, recorded voices, and device-specific information are not included. To take your photos to a new phone, use "Export with photos (ZIP)". When you use Android's feature to transfer data directly to a new device, photos may be transferred along with your records and settings; recorded voices are not transferred.
When you uninstall: Uninstalling the app or clearing its data deletes the records, photos, voices, settings, and the app's automatic backups stored on your device. Files you have exported and milestone cards saved to your device's photos remain until you delete them.

3.3 Information We Explicitly Do Not Collect

Your child's name, date of birth, photos, and similar details, or any of your records, including health-related information
Your recorded voices, or anything captured by the microphone
Your name, email address, phone number, or contacts (the app has no account or sign-up)
Your location
Biometric information such as your fingerprint or face
Your advertising ID (AAID) or app usage statistics (the app does not use Google Analytics)

8. Your Rights

Depending on where you reside (e.g., the EEA, UK, California, Japan), you may have the right to request access to, correction of, or deletion of the limited information we hold. We do not hold your child's records, photos, or voices, so you can view, correct, and delete them yourself on your device. You can:

Delete records, photos, and voices in the app at any time and empty "Recently deleted", or uninstall the app or clear its data to erase everything stored on your device
Withdraw the notification, alarms & reminders, or microphone permission in your device settings at any time

Contact us at the address below to make a request regarding the information we hold

9. Children's Privacy

Baby Tracker Pro is designed to be used by parents and other adult caregivers. It is not intended to be used by children themselves. Information about children (name, date of birth, photos, health-related records, and so on) is entered by the parent or caregiver and stored only on the device. We never receive it.

10. Not Medical Advice

The growth chart (created by the app from the values of the 2023 National Growth Survey on Preschool Children by the Children and Families Agency, Japan), the next nap window, the stool color guide, and other indicators are general guides, not medical advice. If you are worried about your child's health, please consult a doctor.
