Terms of Service

Effective date: November 12, 2026 · Last updated: November 12, 2026

1. Agreement to these Terms

These Terms of Service (“Terms”) govern your use of the mobile game Spot the Difference (the “App”) and its related online services. “We”, “us” and “our” refer to the developer of the App as listed on its Google Play store page.

By downloading, installing or using the App, you agree to these Terms and to our Privacy Policy. If you do not agree, please do not use the App.

2. The game

The App is a casual puzzle game. In each level you compare two pictures and find all the differences before time runs out. Levels are grouped into themes; each level you clear reveals a piece of the theme’s picture, and completing a theme unlocks the next one. You can earn coins, use hints and add-time items, and claim a daily check-in reward.

The App needs an internet connection to load levels and to save your progress, coins and items. Game content such as pictures, themes and levels may be added, changed or removed over time.

3. Who can use the App

The App is intended for a general audience. If you are under the age of majority where you live, you may use the App only with the involvement and permission of a parent or legal guardian, who agrees to these Terms on your behalf.

4. Your license to use the App

Subject to these Terms, we grant you a personal, limited, non-exclusive, non-transferable and revocable license to install and use the App on devices you own or control, for your own non-commercial entertainment. Google Play’s terms also apply to your download and use of the App.

5. Device ID and saved progress

The App does not use accounts. Instead, it creates a random device ID on your device, and our server saves your progress, coins and items under that ID. If you clear the App’s data, uninstall the App or change devices, a new ID is created and your earlier progress may not carry over. Keep a copy of your device ID (Settings → Copy device ID) if you might need our help with your progress.

6. Coins and items

The App includes virtual coins and items, such as hints and add-time items (together, “Virtual Items”).

Virtual Items are earned only by playing, for example as level-clear rewards, the daily check-in or the welcome gift. The current version of the App does not sell Virtual Items or anything else for real money.
Virtual Items have no monetary value, cannot be exchanged for cash or any other real-world item, and cannot be sold, transferred or traded.
You receive a limited license to use Virtual Items within the App; you do not own them.
We may change how Virtual Items are earned, priced in coins or used, for example to balance the game.
We may remove Virtual Items obtained through bugs, cheating or other abuse.
Virtual Items may be lost if your device ID changes (see section 5) or if the App is discontinued (see section 9).

If we ever offer paid features, the price and any additional terms will be shown before you buy, and payments will be handled through Google Play under its policies.

7. Acceptable use

You agree not to:

cheat, or use bots, scripts, modified clients or other unauthorized tools to play or to obtain Virtual Items;
exploit bugs or errors instead of reporting them to us;
interfere with, overload, probe or attack our servers or the App’s security;
use another person’s device ID or attempt to access data that is not yours;
copy, extract, redistribute or commercially exploit the App’s pictures, levels or other content;
reverse engineer or decompile the App, except where the law expressly allows it;
use the App in any way that is unlawful or that harms other people.

8. Intellectual property

The App and all of its content, including pictures, level designs, artwork, interface, text, sounds and software, belong to us or our licensors and are protected by intellectual-property laws. Except for the limited license in section 4, these Terms do not give you any rights to them.

Some sound and music in the App are third-party works released under the CC0 1.0 public-domain dedication. They are credited on the About page.

9. Updates and availability

We may update the App from time to time, and some updates may be required to keep playing. We work to keep the game available, but it may be interrupted for maintenance, updates, technical problems or reasons outside our control, and we do not guarantee that it will always be available or error-free.

We may stop offering the App or its online services. If we do, we will give reasonable advance notice in the App or on this website where possible. Virtual Items have no cash value and are not refundable when the service ends.

10. Termination

You may stop using the App at any time by uninstalling it, and you can ask us to delete your game data as described in the Privacy Policy. We may suspend or end your access to the online services, or reset the related game data, if you seriously or repeatedly break these Terms or if required by law. Sections 6, 8, 11, 12 and 13 continue to apply after termination.

11. Disclaimers

The App is provided “as is” and “as available”. To the extent permitted by law, we make no warranties of any kind, express or implied, including warranties of merchantability, fitness for a particular purpose and non-infringement, and we do not warrant that the App will be uninterrupted, error-free, or compatible with every device.

12. Limitation of liability

To the extent permitted by law, we will not be liable for any indirect, incidental, special, consequential or punitive damages, or for any loss of data, progress, Virtual Items or profits, arising from or related to your use of the App. Because the App is provided free of charge, our total liability to you for any claim relating to the App is limited to fifty U.S. dollars (US$50).

Nothing in these Terms limits or excludes liability that cannot be limited or excluded by law, such as liability for death or personal injury caused by negligence, for fraud, or your statutory rights as a consumer in your country of residence.

13. Governing law and disputes

These Terms are governed by the laws of the place where we are established, without regard to its conflict-of-law rules. If you have a concern, please contact us first; most issues can be resolved quickly by email. If a dispute cannot be resolved informally, it will be decided by the competent courts of that place, unless the mandatory consumer laws of your country of residence give you the right to bring proceedings in your local courts, in which case you keep that right.

If any part of these Terms is found to be unenforceable, the rest remains in effect. Our failure to enforce any part of these Terms is not a waiver. You may not transfer your rights under these Terms; we may transfer ours in connection with a sale or transfer of the App.

14. Changes to these Terms

We may update these Terms from time to time. We will post the updated version on this page and change the “Last updated” date. If the changes are significant, we will also let you know in the App before they take effect. If you keep using the App after the changes take effect, you accept the updated Terms.
