Privacy Policy

Drop That Due (the "App"). This page informs you of our policies regarding the collection, use, and disclosure of personal data when you use our App.

1. No Data Collection – Complete Offline Operation

The App operates 100% offline. It does not require an internet connection, does not request any network permissions, and does not collect, transmit, or store any personal or usage data on any server.

All information you enter into the App (such as item names, expiry dates, quantities, categories, notes, barcodes) is stored exclusively on your local device using a local SQLite database. We have no ability to access, view, or retrieve any of this data.

2. No Account, No Tracking, No Third-Party Services

• The App does not require you to create an account or log in.
• The App does not use any analytics, crash reporting, or advertising SDKs.
• The App does not integrate any third‑party cloud services, backend servers, or push notification gateways that would require data transmission.

Local notifications (reminders) are generated and scheduled entirely on your device; no notification data is sent to us or to any third party.

3. Permissions Used

The App may request the following permissions only for local functionality:

• Notification permission (optional): to display expiry reminders as local notifications and update the app icon badge count.
• Calendar permission (optional): to add events to your system calendar at your request; no calendar data is read or transmitted.

All permissions can be revoked at any time in your device settings. The App does not request camera, microphone, location, storage (beyond its own private directory), or internet access.

4. Data Export and Deletion

• You can export your data (items, categories) as a CSV file at any time. We never access or receive this file.
• You can delete all App data by using the “Clear all data” option inside the App’s settings, or by uninstalling the App.

5. Children’s Privacy

The App does not knowingly collect any personal information from children under the age of 13. Because all data remains on the user’s device and is never transmitted, we do not process or store any child‑related data.

6. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page, and the “Last updated” date will be revised. You are advised to review this page periodically for any changes.
