Privacy Policy

Last updated: June 18, 2026

1. Overview

Gridfulness was built as a clean, minimalist puzzle experience. We believe that your digital downtime shouldn't come at the cost of your personal privacy. Our data principles are absolute: we do not track you, we do not profile you, and we do not collect your personal information.

2. Data Collection

The Gridfulness mobile application functions entirely client-side on your device. It does not require a user account, registration, or an internet connection to generate or play puzzles.

  • Personal Identification: We collect zero names, email addresses, phone numbers, or hardware IDs.
  • Gameplay Progress: Your clear states, times, and chosen difficulty settings are saved strictly locally on your device via secure sandbox storage. This data never leaves your hardware.
  • Analytics: The app does not embed third-party analytics frameworks, advertising trackers, or tracking SDKs.

3. Monetization Transparency

We believe software should treat its users with respect. Our approach to monetization is simple, honest, and completely free of predatory patterns:

  • No Ads, Ever: There are no banner ads, no video popups, and no interstitial commercial breaks to ruin your flow.
  • Free Daily Access: Every single day, you can clear a selection of free grids. No strings attached, resetting every 24 hours.
  • No Monthly Subscriptions: We find monthly subscriptions exhausting and unnecessary for a single-focus puzzle game. We will never ask you to sign up for a recurring monthly bill.
  • Fair & Sustainable Support: To ensure we can safely pay store developer fees and maintain app updates, we need a small amount of revenue. If you choose to unlock infinite, unlimited daily grids, we offer a straightforward **Annual Pass** priced at the local equivalent of just **$1 USD for the entire year**.

4. Children's Privacy

Because our application collects no personal identifiers or geolocation data from any user, it is fully compliant with COPPA (Children's Online Privacy Protection Act) and global digital protection criteria.

5. Store Disclosures

When downloading this app through the Apple App Store or Google Play Store, those platforms may collect diagnostic crash report diagnostics or aggregate installation statistics. Please consult their respective operational agreements to view their platform-level management protocols.
