Privacy Policy — Daily Idioms

 Effective Date: November 11, 2025

Last Updated: November 11, 2025
Welcome to Daily Idioms (the “App”), developed by [Your Name or Company Name] (“we”, “our”, “us”).
Your privacy is very important to us. This Privacy Policy explains how we collect, use, and protect information when you use the Daily Idioms mobile application available on Google Play.
By installing or using this App, you agree to this Privacy Policy.
1. Information We Collect
1.1. Information You Provide Voluntarily
You can use Daily Idioms fully without creating an account.
If you choose to sign in (optional), we may collect:
  • Email address — for backup and sync across devices.
  • Basic profile name (optional) — if signing in with Google or Apple.
This data is used only to identify your account and sync progress.
You can delete it at any time from Settings → Data Control.
1.2. Information Automatically Collected
For functionality and performance, the app may collect limited non-personal data such as:
  • App usage data (e.g., which idioms you viewed or quizzes you completed) — stored locally or anonymously in the cloud for progress tracking.
  • Device information (model, OS version, language, and crash logs) — used to improve app stability and performance.
We do not collect or store sensitive information such as contacts, messages, files, photos, or precise location.
1.3. Optional Analytics
If you allow analytics, we may use tools like Google Firebase Analytics to understand general app usage patterns (e.g., which screens are most popular).
All analytics are:
  • Non-personalized
  • Aggregated and anonymized
  • Used only to improve app experience
You can disable analytics anytime in Settings → Privacy Controls.
1.4. Advertising (If Enabled)
If the free version displays ads, they are served by Google AdMob using non-personalized ads by default.
This means:
  • No tracking or behavioral profiling
  • No access to device identifiers or personal data
  • Ads are based on general context (e.g., app content, language)
You can opt out of ads completely by upgrading to the ad-free version.
2. How We Use Your Data
We use the limited data we collect for:
  • Providing and improving app functionality
  • Syncing your learning progress (if signed in)
  • Sending optional daily reminders (if enabled)
  • Fixing bugs and improving app performance
  • Responding to user feedback and support requests
We never sell, rent, or trade your personal data to third parties.
3. Data Storage and Security
  • Your data is stored locally on your device by default.
  • If you sign in, your data is securely synced via Google Firebase or a similar trusted cloud service using TLS encryption.
  • All access is protected by strong authentication and modern encryption methods.
  • We regularly monitor for security vulnerabilities and apply patches promptly.
4. Data Sharing
We may share limited, non-personal data only with trusted third-party processors necessary for app operation:
  • Google Firebase (analytics, crash reporting, authentication)
  • Google Play Billing (for in-app purchases)
  • AdMob (for optional, non-personalized ads)
All processors act under strict Data Processing Agreements (DPAs) and comply with GDPR/CCPA standards.
We do not share data with social networks, data brokers, or unauthorized parties.
5. Data Retention and Deletion
  • Local app data stays on your device until you uninstall or delete it.
  • If you use a signed-in account, data is retained until you delete your account or request deletion.
  • After deletion, backup and synced data are permanently removed within 30 days.
You can erase or export your data anytime from Settings → Data Control.
6. Children’s Privacy
Daily Idioms is intended for users aged 13 and above.
We do not knowingly collect data from children under 13.
If you are a parent or guardian and believe your child has provided personal information, please contact us — we will promptly delete it.
