Privacy Policy

Futoshiki — Logic Puzzle

Effective date: 14 September 2026

In short: Futoshiki does not ask you to create an account and collects no personal information directly. Your game progress stays on your own device. Because the app shows ads and offers in-app purchases, Google and RevenueCat process some data, as explained below.

1. Who we are

This app is developed by Emre Özgöz. For any privacy question: emreozgoz@gmail.com

2. Data stored on your device

The following is kept only in your device's own storage. It is never sent to us or to any server, and it is not shared with other users. Uninstalling the app deletes all of it.

Levels you completed, stars earned and completion times
Your coin balance and spending history
Preferences such as sound, haptics and theme
Whether you purchased the "Remove Ads" product

3. Data processed by third parties

Service	Purpose	Data processed
Google AdMob	Serving ads	Device advertising ID, IP address, device and OS information, ad impression and click data
Google User Messaging Platform	Collecting ad consent	Your consent choice, approximate (country-level) location
Google Play Billing	Processing purchases	Purchase history. Your payment details are handled by Google and never reach the app
RevenueCat	Validating and restoring purchases	A randomly generated anonymous user ID, purchase records, device and country information
Google Play	Crash reporting	Crash logs and basic device information (collected by the Android system)

These services have their own privacy policies: Google · RevenueCat

4. Your ad choices

Users in the European Union, the United Kingdom and Switzerland are shown a consent form on first launch. If you do not consent to personalised ads, ads are served without personalisation.

You can change your choice at any time:

In the app: Settings → Ad preferences
On your device: Android Settings → Google → Ads, where you can reset or delete your advertising ID

5. Children

Futoshiki is not directed at children under 13, and we do not knowingly collect data from that age group. If you believe a child under 13 has had data processed, please contact us and we will act on it.

6. Deleting your data

The app creates no account, so there is no account to delete. To erase all game data on your device, simply uninstall the app. If you want your purchase records deleted, write to emreozgoz@gmail.com and we will resolve the request within 30 days. Your purchase history on Google Play is subject to Google's own retention policy.

7. Security

All connections the app makes to the outside world are encrypted (HTTPS/TLS). Game data on your device is kept in the app's private storage and cannot be read by other apps.

8. Changes

If this policy changes, we will update this page and change the effective date above. For significant changes we will notify you inside the app.
