Privacy Policy Generator

Generates a comprehensive privacy policy for Android apps by scanning the project and creating a GitHub Pages-ready Markdown document.

Overview

Why this is needed:

• Google Play requires a privacy policy URL for all apps
• Privacy policy must be on a publicly accessible, non-geofenced URL
• Cannot be a PDF (must be HTML or plain text)
• Health Connect apps have additional disclosure requirements

What this skill does:

1. Scans AndroidManifest.xml for permissions and features
2. Analyzes build.gradle for third-party SDKs
3. Detects Health Connect integration
4. Prompts for missing information
5. Generates privacy policy in Markdown
6. Provides GitHub Pages setup instructions

Prerequisites

• Android project with AndroidManifest.xml
• Git repository (for GitHub Pages hosting)
• Build configuration files (build.gradle.kts)

Inputs

Process

Step 1: Scan Project for App Information

Extract from AndroidManifest.xml:

# Get package name
PACKAGE_NAME=$(grep "package=" app/src/main/AndroidManifest.xml | head -1 | sed 's/.*package="\([^"]*\)".*/\1/')
echo "Package: $PACKAGE_NAME"

# Get app name (from strings.xml)
APP_NAME=$(grep 'name="app_name"' app/src/main/res/values/strings.xml | sed 's/.*>\([^<]*\)<.*/\1/')
echo "App name: $APP_NAME"

# Check for permissions
echo "Scanning permissions..."
PERMISSIONS=$(grep "<uses-permission" app/src/main/AndroidManifest.xml | sed 's/.*android:name="\([^"]*\)".*/\1/')

# Check for Health Connect
HEALTH_CONNECT=$(echo "$PERMISSIONS" | grep -i "health" || echo "")
if [[ -n "$HEALTH_CONNECT" ]]; then
    echo "✓ Health Connect detected"
fi

Step 2: Analyze Third-Party SDKs

Scan build.gradle.kts for common libraries:

echo "Scanning dependencies..."

# Check for analytics
ANALYTICS=""
grep -q "firebase-analytics" app/build.gradle.kts && ANALYTICS="$ANALYTICS Firebase Analytics,"
grep -q "google-analytics" app/build.gradle.kts && ANALYTICS="$ANALYTICS Google Analytics,"

# Check for ads
ADS=""
grep -q "admob" app/build.gradle.kts && ADS="$ADS AdMob,"
grep -q "facebook-ads" app/build.gradle.kts && ADS="$ADS Facebook Audience Network,"

# Check for crash reporting
CRASH_REPORTING=""
grep -q "crashlytics" app/build.gradle.kts && CRASH_REPORTING="$CRASH_REPORTING Firebase Crashlytics,"

echo "Analytics: ${ANALYTICS:-None}"
echo "Ads: ${ADS:-None}"
echo "Crash reporting: ${CRASH_REPORTING:-None}"

Step 3: Detect Health Connect Data Types

If Health Connect is detected, extract data types:

# Scan for Health Connect permission declarations
HEALTH_PERMISSIONS=$(grep "health.permission" app/src/main/AndroidManifest.xml || echo "")

# Common Health Connect data types
echo "Health data types detected:"
echo "$HEALTH_PERMISSIONS" | grep -i "STEPS" && echo "  - Steps (read/write)"
echo "$HEALTH_PERMISSIONS" | grep -i "HEART_RATE" && echo "  - Heart rate (read)"
echo "$HEALTH_PERMISSIONS" | grep -i "SLEEP" && echo "  - Sleep sessions (read)"
echo "$HEALTH_PERMISSIONS" | grep -i "EXERCISE" && echo "  - Exercise sessions (read/write)"

Step 4: Prompt User for Missing Information

Ask user for required information:

Developer/Company Name: (Detected from git config: {git config user.name}) Press Enter to use detected value, or type a different name:

Contact Email: (Detected from git config: {git config user.email}) Press Enter to use detected value, or type a different email:

App Type:

1. Free (no ads, no purchases)
2. Free with ads
3. Free with in-app purchases
4. Paid
5. Open source Select option (1-5):

Data Storage:

1. All data stays on device (no cloud sync)
2. Data synced to cloud (specify service)
3. Both local and cloud storage Select option (1-3):

Step 5: Generate Privacy Policy

Create docs/privacy-policy.md using the template:

# Privacy Policy for {APP_NAME}

**Last updated:** {CURRENT_DATE}

{DEVELOPER_NAME} built the {APP_NAME} app as {APP_TYPE}. This SERVICE is provided at no cost and is intended for use as is.

Step 6: Create Privacy Setup Instructions

Create docs/PRIVACY_SETUP.md:

# Privacy Policy Setup for GitHub Pages

## Overview

Your privacy policy has been generated at `docs/privacy-policy.md` and is ready to be hosted on GitHub Pages.

## Setup Steps

### 1. Enable GitHub Pages

1. Go to your repository on GitHub
2. Navigate to **Settings** → **Pages**
3. Under "Source", select **Deploy from a branch**
4. Select branch: **main** (or **master**)
5. Select folder: **/docs**
6. Click **Save**

### 2. Wait for Deployment

GitHub Pages will automatically build and deploy your site. This usually takes 1-2 minutes.

You can check the deployment status under **Actions** tab.

### 3. Verify Privacy Policy URL

Once deployed, your privacy policy will be available at:

**https://{USERNAME}.github.io/{REPO}/privacy-policy**

Test the URL in your browser to confirm it's accessible.

### 4. Add URL to Play Console

1. Open [Google Play Console](https://play.google.com/console)
2. Select your app
3. Go to **App content** → **Privacy policy**
4. Enter the URL: `https://{USERNAME}.github.io/{REPO}/privacy-policy`
5. Click **Save**

## Custom Domain (Optional)

If you want to use a custom domain:

1. Add a `CNAME` file to `docs/`:

privacy.yourdomain.com

2. Configure DNS at your domain registrar:
- Type: CNAME
- Name: privacy (or your subdomain)
- Value: {USERNAME}.github.io

3. Update the privacy policy URL in Play Console

## Health Apps Declaration

⚠️ **Important:** If your app uses Health Connect, you must also:

1. Go to Play Console → **App content** → **Health**
2. Complete the Health Apps declaration form
3. List all health data types your app accesses
4. Explain how the data is used
5. Confirm your privacy policy includes health data disclosure

## Troubleshooting

### "404 Not Found"
- Wait 2-3 minutes for deployment to complete
- Verify GitHub Pages is enabled in repository settings
- Check that `docs/privacy-policy.md` exists on main branch

### "Privacy policy URL required"
- Ensure URL is publicly accessible (not behind login)
- URL must use HTTPS
- Cannot be a PDF or editable document

## Next Steps

After privacy policy is live:
- Test the URL is publicly accessible
- Add URL to Play Console
- Complete other Play Console requirements (content rating, data safety, etc.)
- Run `/devtools:android-playstore-scan` to verify all requirements

Verification

MANDATORY: Run these commands:

# Verify privacy policy created
test -f docs/privacy-policy.md && echo "✓ Privacy policy created"

# Verify setup guide created
test -f docs/PRIVACY_SETUP.md && echo "✓ Setup guide created"

# Check privacy policy contains required sections
grep -q "Privacy Policy" docs/privacy-policy.md && echo "✓ Title present"
grep -q "Contact" docs/privacy-policy.md && echo "✓ Contact info present"

# Check for Health Connect section if applicable
if grep -q "health.permission" app/src/main/AndroidManifest.xml; then
    grep -q "Health Data" docs/privacy-policy.md && echo "✓ Health data section present"
fi

Expected output:

• ✓ Privacy policy created
• ✓ Setup guide created
• ✓ Title present
• ✓ Contact info present
• (✓ Health data section present - if Health Connect is used)

Outputs

Templates

Health Connect Data Purpose Examples

For the health data purpose section, use one of these based on user input:

• Fitness tracking: "to track your fitness activities and provide insights into your health patterns"
• Health monitoring: "to monitor your health metrics and help you achieve your wellness goals"
• Data sync: "to sync your health data across devices"
• Custom: User provides their own description

Third-Party Service Links

Common third-party services and their privacy policy URLs:

• Health Connect: https://support.google.com/android/answer/12098244
• Firebase Analytics: https://firebase.google.com/policies/analytics
• Google Analytics: https://policies.google.com/privacy
• AdMob: https://support.google.com/admob/answer/6128543
• Crashlytics: https://firebase.google.com/support/privacy

Troubleshooting

"Cannot find app name"

Cause: app_name not defined in strings.xml Fix: Add <string name="app_name">Your App Name</string> to res/values/strings.xml

"Git config not found"

Cause: Git user not configured Fix: Run git config --global user.name "Your Name" and git config --global user.email "email@example.com"

"Health permissions not detected"

Cause: Health Connect permissions not declared in manifest Fix: Verify permissions are correctly declared in AndroidManifest.xml
