PRIVACY POLICY

Last Updated: March 10, 2026

1. Introduction

Welcome to Nonogram Solver. This application is a hobbyist project created and maintained by codened ("I", "Me", or "Administrator"). Your privacy is important to me, and this document explains how I handle data.

2. Information I Collect

I do not collect personal data such as your name, email address, or phone number. However, to improve the game experience, I collect:

  • Analytical Data: I use a unique identifier known as a UUID (Universally Unique Identifier) stored in your browser's local storage or cookies.
  • Game Progress: Information about completed puzzles, time spent on levels, and app performance.

3. Purpose of Data Processing

I process the data mentioned above for the following purposes:

  • Analytics: To understand how many people are playing the game and which levels are too easy or too difficult.
  • Optimization: To find and fix bugs and improve the user interface.
  • Legal Basis: This data is processed based on your consent, which you provide via the cookie consent banner.

4. How UUID Works

A UUID is a random string of characters that distinguishes your session from others.

  • It does not allow me to identify who you are in real life.
  • It allows the app to remember that it is the same user returning to finish a puzzle.
  • You can delete this identifier at any time by clearing your browser's cache or cookies.

5. Data Retention

  • Analytical data associated with your UUID is stored for a period of 12 months.
  • If you reject tracking, no UUID will be generated or stored.

6. Third-Party Services

I use the following third-party services to host the app and process data:

  • Hosting Provider: vercel.com (Data is stored on their secure servers).
  • Analytics Tool: Supabase Database.

7. Your Rights

Under the GDPR, you have the right to:

  • Access the data I have about your session.
  • Request the deletion of your data (Right to be Forgotten).
  • Withdraw your consent for analytical tracking at any time.

8. Contact
