Simple rules, plain language.

1. License — what you may do

• DairyYield Pro is provided free of charge for personal and commercial use in your own dairy business (farm, collection centre, processing plant, consultancy work for your own clients).
• You may install it on any number of Android devices you use for your work.
• You may share the official download link to this website with anyone.
• You may not sell the app, re-upload the APK to other websites or app stores as your own, modify and redistribute it, or remove its branding.

2. Estimates — accuracy disclaimer

• All yields, economics and standardization results are mathematical estimates based on standard Fat/SNF mass-balance and the recovery/loss percentages configured in Product Settings.
• Actual plant output varies with milk quality, season, equipment and process. Always validate figures against your own plant trials before making purchasing, pricing or contractual decisions.
• To the maximum extent permitted by law, we are not liable for losses arising from decisions made using the app's estimates.

3. Your data — your responsibility

• Everything you enter (farmer batches, history, settings) is stored only on your device. We cannot see, recover or restore it.
• Back up regularly using Data & Backup Centre → Export Backup, and keep the backup file somewhere safe (for example, send it to yourself on WhatsApp or email).
• Uninstalling the app or clearing its storage deletes its on-device data permanently unless you have an exported backup.

4. Safe download rules

• Download the APK only from this official website. Copies from other sources may be modified and unsafe.
• Verify your download if you wish: the SHA-256 fingerprint of the official v2.1.0 APK is printed in the download section of the home page.
• The app requests no permissions and needs no internet. If a "DairyYield Pro" copy ever asks for contacts, SMS, location or similar permissions, it is not our app — delete it.

5. Availability & updates

• The app is provided "as is", without warranties of any kind, express or implied.
• We may release improved versions on this website from time to time. Updates install over your existing app and keep your data; exporting a backup before updating is still recommended.
• Older versions keep working — nothing in the app expires or phones home.

6. Acceptable use

• Use the app for lawful dairy-business purposes.
• Do not attempt to misrepresent the app's output as a Government or FSSAI certification, laboratory report, or official document.

7. Governing law

These terms are governed by the laws of India. Any dispute will be subject to the jurisdiction of the courts of Maharashtra, India.

8. Changes

If these terms change, the updated version will be published at this address before it takes effect. Continuing to use a newly downloaded version means you accept the updated terms.
