Privacy Policy for Deep Battery

Last Updated: March 9, 2026

This Privacy Policy explains how Deep Battery collects, uses, and discloses information when you use our mobile application to monitor battery health and usage.

Google Drive & Battery Data: We prioritize your data ownership. Detailed battery logs (voltage, health, temperature) are stored locally on your device or in your personal Google Drive. We do NOT host your battery history on our own servers.

1. Data Collected By The App Developer

We collect the minimum data required to manage your account, verify premium subscriptions, and sync settings across devices.

Data Type	Source/SDK	Purpose
Google Account Email & ID	Google Sign-In	To create your account, sync your preferences, and provide access to the Deletion Portal.
Purchase History	RevenueCat & Google Play	To validate your subscription status, unlock Pro features, and manage billing history.
Device Metadata	System API	Basic info (model, OS version) to ensure the battery monitoring algorithms are calibrated correctly for your hardware.

2. Information NOT Collected or Stored By the Developer

To ensure your privacy, we do NOT collect or have access to:

Detailed Usage Logs: Specific timestamps of when you use certain apps or your exact charging habits are stored only in your private database (Local or Google Drive).
Location Data: We do not track where you charge your device.
Personal Files: Aside from the specific folder created for backups on Google Drive, we cannot see or access any other files in your cloud storage.

3. Third-Party Services

We use industry-standard partners to provide advertising and subscription management. These partners collect data according to their own policies.

A. Google AdMob (Advertising)

AdMob may collect device identifiers (like Advertising ID) and IP addresses to serve relevant ads and prevent click fraud. You can reset your Advertising ID in your Android system settings.

B. RevenueCat (Subscription Management)

We use RevenueCat to process and track in-app purchases reliably. RevenueCat receives an anonymous identifier and your purchase history to ensure your "Pro" features work across all your devices.

C. Google Play Billing

All financial transactions are handled by Google. We never see or store your credit card or bank details.

4. Data Rights and Deletion

You have full control over your data. You may:

Disconnect your Google Drive at any time within the app settings.
Request a permanent deletion of your account and associated sign-in metadata via our Account Deletion Portal.
