Privacy Policy

Ruhul Rahat ("we," "our," or "us") operates the Simple Car Maintenance Log mobile application (the "App") under the package name com.simplelog.carlog.

We are dedicated to safeguarding your privacy. This Privacy Policy details our practices concerning the processing of information gathered through our App.

1. Summary (Privacy by Design & Zero Server Collection)

The Simple Car Maintenance Log is designed with a 100% offline-first, local-first database architecture.

• No Account Required: You do not need to register, verify an email, or sign up to use the App.
• No Cloud Transmission: All service logs, vehicle information, and mileage values you enter are saved exclusively on your local device. We do not operate external database servers, and your inputs are never uploaded to the cloud.
• No Background Operations: The App does not perform background tracking, location capture, or background network syncs.

2. Information We Process

Since all workflows take place entirely on your device, we have zero access to your information:

A. Data You Input (Stored Locally Only)

You manually enter and manage the following details:

• Vehicle profiles (make, model, year, and plate numbers).
• Maintenance logs (oil changes, tire service, brake repairs, custom service records, dates, prices, and odometer metrics).
• Reminders (maintenance milestones and target dates).

All entries are saved securely in your device's private sandbox partition and are never transmitted to us or any third parties.

B. Device Permissions

The App may request the following permissions to enable specific user actions:

• Storage / Photos / Files (Export Access): Used exclusively to compile and export your car maintenance reports locally to CSV files or share service records. We do not scan, browse, or read any other files or directories on your device.

3. Data Sharing and Disclosure

• No Third-Party Sharing: We do not collect, monetize, sell, trade, or share any data inputted into the App with third-party advertising companies, data brokers, or analytics suites.
• No Possibility of Disclosing Data: Because your records are stored solely on your device and are never synchronized to our systems, we do not possess any of your data and cannot disclose it to any third parties or legal authorities.

4. Data Control and Deletion

• Complete Control: You hold absolute ownership over your logs. You can delete or edit any service record or vehicle at any time.
• Permanent Data Deletion: If you wish to wipe all data permanently, you can easily do so by:
  1. Going to your Android system settings, choosing the App, and selecting "Clear Storage" or "Clear Data."
  2. Uninstalling the App.

Uninstalling the App permanently and immediately deletes all local files and database directories created by the App. This data cannot be recovered.

5. Children's Privacy (COPPA)

Our App is not directed at children under the age of 13. Since the App collects zero personal data or device identifiers, it is fully compliant with the Children's Online Privacy Protection Act (COPPA).

6. Updates to This Policy

We may revise this Privacy Policy periodically. We will alert you to changes by publishing the updated version on this page and revising the "Last Updated" date. You are encouraged to review this page regularly.
