# Privacy Policy — FlinkLog

**Last updated:** June 17, 2026

## Overview

FlinkLog ("the App") is a free Android application developed by Arun Yogeshwaran. This privacy
policy explains how the App handles your information.

## Data Collection & Open Source Transparency

**FlinkLog is 100% open-source and does not collect, store, or transmit any personal data to external servers.**

Because the App is fully open-source under the GPLv3 license, the entire codebase is public and auditable. You can inspect the source code on GitHub to verify that there are no tracking SDKs, advertising libraries, or hidden network permissions.

All workout data you enter (workout type, date, and time) is stored **exclusively on your device** using a local database. No data ever leaves your device.

## Data We Do NOT Collect

- ❌ Personal information (name, email, phone number)
- ❌ Location data
- ❌ Device identifiers or advertising IDs
- ❌ Usage analytics or telemetry
- ❌ Crash reports (not collected by the App itself)
- ❌ Any data transmitted over the internet

## Internet Access

The App does **not** require or request internet access. It works entirely offline.

## Third-Party Services

The App does **not** use any third-party services, SDKs, or analytics tools.

## Data Storage

All data is stored locally on your device using Android's Room (SQLite) database. To protect your
workout history and custom exercises when you switch devices, the App supports **Android Auto Backup
**. All local database files (including transaction logs) are securely backed up to the private
Google Drive storage associated with your Android Google Account. This backup is fully encrypted
end-to-end, is completely private to you, and does not count against your Google Drive storage
limit. Your workout history will automatically restore when you reinstall the App on a new device.
If you disable Android system backups in your device settings and uninstall the App, all local data
will be permanently deleted.

## On-Device System Integrations (Android AppFunctions)

The App supports Android 16 AppFunctions, which exposes specific capabilities (such as logging
workouts, viewing history, and generating workout suggestions) locally to the Android system. This
integration allows your device's assistant (like Google Gemini) or other system services to perform
these tasks on your behalf. All AppFunctions processing is done entirely on-device, and no workout
data is collected or transmitted to external servers.

## Children's Privacy

The App does not knowingly collect any personal information from anyone, including children under
13. Since no data is collected at all, the App is safe for users of all ages.

## Changes to This Policy

If this privacy policy is updated, the changes will be posted on this page with an updated "Last
updated" date.
