Privacy Policy

Last updated: February 17, 2026

Grid Genius ("we", "our", "us") operates the Grid Genius crossword puzzle application and website at gridgenius.app. This policy explains what data we collect, why we collect it, and your rights regarding that data.

1. Data We Collect

Account Information

When you sign in with Google or Apple, we receive and store:

  • Email address
  • Display name
  • Profile photo URL

We do not receive or store your Google or Apple password.

Gameplay Data

We store data about your puzzles and progress, including:

  • Puzzles played, completed, and in-progress grid states
  • Solve times, hints used, and difficulty preferences
  • Daily challenge results, streaks, and leaderboard rankings
  • Ratings, reviews, and comments you post
  • Achievements and statistics

Device and Usage Data

We automatically collect:

  • Device type, browser, and operating system
  • Screen dimensions
  • Pages visited and interaction events (button clicks, scroll depth, time on page)
  • Referring URL
  • Approximate location (country level, derived from IP address)

We do not collect precise geolocation data.

Preferences and Settings

We store your in-app preferences such as theme (light/dark), sound, haptic feedback, notification settings, and daily reminder times.

2. How We Use Your Data

  • Provide the service: authenticate your account, save your progress, generate personalized puzzles, and maintain streaks and leaderboards.
  • Improve the product: understand how features are used, run A/B tests on landing pages, and identify bugs.
  • Communicate with you: send push notifications for daily challenges, streak reminders, and achievement alerts (if you opt in).
  • Process payments: manage subscriptions and in-app purchases through our payment providers.
  • Show ads: display rewarded video ads in exchange for in-app hints (free-tier users only).

3. Third-Party Services

We use the following third-party services that may process your data under their own privacy policies:

Service Purpose
Firebase (Google)Authentication, push notifications
Google AdMobRewarded video ads
RevenueCatIn-app purchase management (iOS, Android)
Dodo PaymentsWeb subscription processing
PostHogProduct analytics and A/B testing
Microsoft ClarityHeatmaps and session recordings
Google GeminiAI puzzle generation
CloudflareHosting, CDN, and DNS

Payment information (credit card numbers, billing details) is handled entirely by RevenueCat, Dodo Payments, Apple, and Google. We never see, store, or process your payment card data.

4. Session Recording

We use PostHog and Microsoft Clarity on our landing pages to record user sessions (mouse movements, clicks, and scrolls). These recordings help us understand how visitors interact with our pages and improve the user experience. Password fields are always masked. Session recordings are not used on the main application.

5. Cookies and Local Storage

We use browser local storage (not traditional cookies) to store:

  • A randomly generated visitor ID for analytics
  • Your A/B test variant assignment (so you see the same landing page consistently)
  • Authentication tokens for keeping you signed in

Third-party services (PostHog, Clarity, Google) may set their own cookies. You can disable cookies in your browser settings, though some features may not work correctly.

6. Advertising

Free-tier users may watch rewarded video ads to earn in-app hints. These ads are served by Google AdMob, which may use device identifiers and usage data to show relevant ads. You can opt out of ad personalization in your device settings. Premium subscribers do not see ads.

7. AI-Generated Content

We use Google Gemini to generate crossword puzzles. The topics and parameters you choose when creating a puzzle are sent to this service. We do not send your personal information (name, email) to AI providers. Your puzzle preferences are not used to train AI models.

8. Data Retention

We retain your account and gameplay data for as long as your account is active. If you delete your account, we will remove your personal data within 30 days. Anonymized, aggregated analytics data (which cannot identify you) may be retained indefinitely.

9. Data Security

We protect your data with:

  • HTTPS encryption for all data in transit
  • Firebase Authentication with secure token validation
  • Server-side access controls and rate limiting

No method of transmission or storage is 100% secure. If you discover a security vulnerability, please contact us at [email protected].

10. Your Rights

Depending on your location, you may have the right to:

  • Access the personal data we hold about you
  • Correct inaccurate data
  • Delete your account and associated data
  • Export your data in a portable format
  • Object to processing of your data for marketing purposes
  • Withdraw consent for optional data processing (e.g., push notifications, ad personalization)

To exercise any of these rights, email [email protected].

11. Children's Privacy

Grid Genius is not directed at children under 13. We do not knowingly collect personal data from children under 13. If you believe a child has provided us with personal data, please contact us and we will delete it promptly.

12. Changes to This Policy

We may update this policy from time to time. We will notify you of significant changes by posting a notice in the app or on our website. Continued use of Grid Genius after changes constitutes acceptance of the updated policy.
