This Privacy Policy explains how ONESTAR MILK ANALYZERS ("the App"), published by KT Dairy Equipments ("we", "us", "our"), collects, uses, and protects information when you use the App. By using the App, you agree to the practices described in this policy.
1. Who We Are
ONESTAR MILK ANALYZERS is developed and maintained by KT Dairy Equipments to work alongside our physical milk analyzer hardware, helping dairy and milk-collection society owners record, calculate, and manage milk testing data (FAT, SNF, weight, rate, and payment records).
2. Information We Collect
2.1 Information You Provide Directly
Customer / society records: names, phone numbers, and codes you enter for your customers or milk societies, so you can manage their transactions within the App.
App activation serial number: the unique serial number provided to you at the time of hardware purchase, used to activate and unlock the App on your device.
Optional Google account email: if you choose to enable backup, you connect your own personal Google account so your records can be automatically backed up to your own Google Drive.
2.2 Information Collected Automatically
Device identifier: used to lock your activated serial number to your specific device, preventing unauthorized use of the same license on multiple phones.
Bluetooth (BLE) data: the App connects via Bluetooth Low Energy to your physical milk analyzer hardware to receive test readings (FAT, SNF, density, etc.). This data is exchanged locally between your device and your hardware and is not transmitted to our servers.
3. How We Use Your Information
To activate and validate your purchased license against the device you're using.
To let you record, calculate, and manage milk testing and payment data for your customers/societies.
To provide automatic backup of your records to your own Google Drive account, if you choose to enable it.
To provide customer support if you contact us regarding your license or the App.
4. Where Your Data Is Stored
On your device first: all records you enter (customers, sessions, rate charts, transactions) are saved locally on your phone first, instantly, and work fully offline.
Your own Google Drive (optional): if you connect a Google account, a backup copy of your data is saved to a private file in your own Google Drive using Google's restricted drive.file access — meaning the App can only see the specific backup file it creates, not your other Drive files. We (KT Dairy Equipments) do not have access to this backup; it stays in your personal Google account.
License/activation records: we maintain a record of which serial numbers have been issued and activated (linked to the purchasing customer and device), so we can validate licenses and provide support. This is stored securely and used only for license administration.
5. Data Sharing
We do not sell, rent, or share your customer/society records or personal data with third parties for advertising or marketing purposes. Your data is used solely to operate the App's core functionality.
6. Third-Party Services
The App uses the following third-party service strictly to provide its features:
Google Drive API (with Google Sign-In): for optional automatic backup, using your own Google account and a restricted drive.file scope, under Google's own privacy policy.
The App's English/Hindi language option uses built-in app text and does not send any text to an external translation service.
7. Data Security
We take reasonable technical measures to protect your information, including device-based license locking and Google's secure, restricted-scope Drive access for backups. However, no method of electronic storage or transmission is 100% secure, and we cannot guarantee absolute security.
8. Your Choices and Rights
You can use the App fully offline without connecting a Google account — backup is entirely optional.
You can disconnect your Google account from the App at any time from within the Backup & Sync settings.
You can request deletion of your license/activation record by contacting us using the details below.
9. Children's Privacy
The App is intended for business use by dairy and milk-collection society operators and is not directed at children. We do not knowingly collect information from children under 13.
10. Changes to This Policy
We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated "Last updated" date.
11. Delete Your Account & Data
You can request deletion of your data in the following ways:
Disconnect your Google account: open the App > Settings > Backup & Sync > Disconnect. This immediately stops the App from accessing your Google account. No new data will be read from or written to your Google Drive after disconnecting.
Delete your Drive backup file: open Google Drive directly (drive.google.com) using the same Google account, find the App's backup file, and delete it. This is fully under your control since the backup lives in your own Drive, not on our servers.
Delete local records on your device: individual customer and transaction records can be deleted within the App itself. To remove all local data at once, clear the App's storage from your phone's Settings > Apps > ONESTAR MILK ANALYZERS > Storage > Clear data, or uninstall the App.
Delete your license/activation record: to request deletion of the serial number and device-activation record associated with your purchase, contact us using the details below. We will delete this record within a reasonable time, except where a copy must be kept briefly for fraud prevention or legal/accounting requirements.
Data types deleted upon request: customer/society records, activation/device-lock record. Data that may be retained briefly: basic purchase/serial issuance records required for warranty or support history, unless you specifically request their removal as described above.
