Privacy Policy

Last updated: October 11, 2026

This privacy policy applies to the following mobile applications published by Erkan Arslan (developer) on Google Play and the Apple App Store:

Data Collection

Our apps do not collect, store, or transmit any personal data. All data is stored locally on your device only and is never sent to any server or third party. The one exception is the subscription check in Cattle Weight Estimator & Herd, described in its own section below.

Third-Party Services

Some apps offer optional in-app purchases. Payments are processed by the platform store (Apple App Store or Google Play). We do not handle or store any payment information.

We do not use any analytics, advertising, or tracking services.

Purchases

In-app purchases are platform-specific and do not transfer between iOS and Android. Sign in with the same App Store or Google Play account and use “Restore purchases” to unlock previously bought features on all your devices. All payments are handled by the respective store; we store no payment information.

Permissions

Some apps may request device permissions (such as notifications or alarms) to provide their core functionality. These permissions are never used to collect personal data.

Data Storage & Retention

All app data is stored locally on your device. To remove all data, simply uninstall the app. We have no access to your data and cannot retrieve or delete it on your behalf.

Your Rights (GDPR / CCPA)

Since no personal data is collected by us, there is nothing to access, correct, export, or delete on our end. Uninstalling the app removes all locally stored data.

Children's Privacy

Our apps do not collect any information from anyone, including children under 13.

Cattle Weight Estimator & Herd

Your records stay on your device. Animals, weighings, health and breeding records, money entries, vet contacts and photos are stored only on your phone. We do not receive or keep a copy.

Subscriptions. Purchases are processed by Apple or Google. To check whether a subscription is active, the app uses RevenueCat (RevenueCat, Inc.), which receives an anonymous app user ID, your purchase and subscription status, and basic device information such as platform, app version and country. It does not receive your herd records. See the RevenueCat Privacy Policy.

Permissions.

Backups and exports. A backup file, CSV or PDF is created only when you ask for it, and goes only where you choose to save or share it. Anyone you send it to can read it.

Phone calls. Tapping a vet's number opens your phone's dialler. We do not see the call.

Analytics and ads. The app has no analytics, advertising or tracking SDKs.

Deleting your data. Use Settings > Delete all data, or delete the app. To remove your anonymous purchase record from RevenueCat, contact us at the address below.

Not veterinary advice. Weights are estimates from tape measurements, and withdrawal dates are calculated only from what you enter. The app does not suggest medicines, doses or withdrawal periods.

Changes to This Policy

We may update this policy from time to time. Any changes will be reflected on this page with an updated date.
