Privacy Policy – Logic Grid Puzzles & Calcudoku

Effective date: October 8, 2026

This policy explains how the Android app Logic Grid Puzzles & Calcudoku (package com.teknoprojem.logicgrid, "the app"), published by Teknoprojem ("we", "us"), handles information.

The short version

• You do not need an account. We never ask for your name, email address or any other personal details.
• Your progress and settings are stored only on your phone. We do not have a server and cannot see them.
• If the app shows ads, they are provided by Google AdMob, which may collect device data as described below.

Information stored on your device

The app saves your solved puzzles, stars, streaks, achievements, half-finished games and settings (such as theme, language, sound and music) on your device. This information never leaves your device through the app. It is deleted when you uninstall the app or clear its data.

Advertising

The app may show ads provided by Google AdMob. Full-screen ads are never shown in the middle of solving a puzzle; a small banner may appear at the bottom of the screen. When ads are shown, Google may collect and process information such as your device's advertising ID, IP address, approximate location derived from the IP address, device and app information, and how you interact with ads. Google uses this information to deliver, measure and improve ads and to prevent fraud.

If you are in the European Economic Area, the United Kingdom or Switzerland, the app asks for your consent before personalized ads are shown, and you can change your choice at any time from the app's settings. You can also reset your advertising ID or opt out of personalized ads in your Android device settings (Settings → Google → Ads, or Settings → Privacy → Ads).

For details, see Google's Privacy Policy and how Google uses information from apps that use its services.

Ratings and reviews

The app may show Google Play's in-app review prompt. This is handled entirely by Google Play; we do not receive any information from it other than the public review you choose to post.

Feedback emails

If you send us feedback from the app, it opens your own email app. We receive only what you choose to send (your email address and message) and use it only to reply to you. We do not share it with anyone.

Children

The app is intended for a general adult audience and is not directed to children under 13. We do not knowingly collect personal information from children.

Security

Because we do not collect personal data on our own servers, there is no account or database of yours that could be exposed. Data held by Google AdMob is protected under Google's own security practices.

Changes to this policy

If we change this policy, we will update this page and the effective date above.
