Mining Fever

Terms of Use

Mining Fever · Effective date: 10 October 2026 Русская версия

These terms are an agreement between you and TEF SYSTEMS LTD (“we”, “us”) about the mobile game Mining Fever (“the Game”, Android package com.miningfever.game, also for iOS). By installing or using the Game you accept them. If you do not agree, please do not use the Game. How we handle data is described in the Privacy Policy.

1. In short

2. Who we are

The Game is published by TEF SYSTEMS LTD, Paphos, Cyprus. Contact: support@tefs.com.

3. Licence to use the Game

We give you a personal, non-exclusive, non-transferable, revocable licence to install and use the Game on your own devices for your own entertainment, not for business. The Game and everything in it (code, art, sounds, texts, names, the Mining Fever name and logo) belong to us or our licensors. All rights not given here are reserved.

You may not: copy, modify or distribute the Game; reverse engineer or decompile it, except where the law allows this despite this clause; take out and reuse its art or sounds; sell, rent or sub-license the Game or access to it; or use the Game for any unlawful purpose.

4. Virtual items and currency

• The money in the Game ($ cash and BTC), the miners, locations, modules, levels, rewards and everything else you can collect or own in it are virtual game elements. They are part of the entertainment, are not property, have no real-world value and give you no right to anything outside the Game.
• They cannot be bought with real money or Bitcoin, and they cannot be withdrawn, exchanged, sold, lent or transferred for money, Bitcoin or anything else of value, in the Game or outside it. Nothing in the Game costs or gives real money.
• The Game is a simulation. It uses the public market price of Bitcoin only to make the simulation feel alive. No real mining, buying, selling or holding of Bitcoin takes place, and nothing in the Game is financial or investment advice.
• The forecast mini-game is for fun. It costs nothing, and a forecast never takes away your balance.
• The leaderboard is a simulation: the other miners of the network are generated by the Game. They are not real people.
• We may change prices, rates, rules, rewards and balances to keep the Game balanced, fix errors or add features.

5. Ads and rewarded videos

The Game is free and is funded by ads shown by third-party advertising networks, for example banners, ads between screens, an ad when the Game opens, and rewarded videos. A rewarded video is always optional: you choose to watch it for a bonus in the Game, and the bonus is virtual. We do not control the content of ads or the websites and apps they lead to, and what you do there is between you and them. What data advertising services receive is described in the Privacy Policy. Do not click ads or watch videos in an automated or fraudulent way.

6. Fair play

Please play the Game as it is meant to be played. You must not:

• use cheats, hacks, modified or unofficial versions of the Game, emulators or tools that change memory, saved data, the device clock or network traffic to gain an advantage;
• use bots, scripts or other automation to play the Game or to get rewards or ad views;
• exploit errors in the Game on purpose instead of telling us about them;
• interfere with the Game or with the services it relies on, or try to get around its protections.

If you break these rules, we may reset or limit your progress or stop the Game from working on your device, as far as the law allows.

7. Age

The Game is not intended for children. Please do not use it if you are under 13, or under 16 in the European Economic Area, or younger than the age at which the law of your country lets you agree to the processing of your data yourself. The Game does not ask your age and has no age check.

8. Updates, availability and your progress

• We may update the Game, change or remove features, and stop offering the Game. Some updates may be needed to keep playing. We do not promise that the Game will always be available or free of errors, and we are not obliged to provide a particular level of maintenance or support.
• Your progress is stored only on your device. We have no accounts and no cloud save, so we cannot restore it. Uninstalling the Game or clearing its data deletes your progress. Your phone’s own backup may restore it, depending on your device settings.

9. Google Play and the App Store

If you get the Game from Google Play or the Apple App Store, these terms are between you and us only, and not between you and Google or Apple. Google and Apple are not responsible for the Game, its content, support or maintenance, and have no duty to provide maintenance or support for it. Apple and Google, and their subsidiaries, may enforce these terms against you as third-party beneficiaries where their store rules say so. You must also follow the terms of the store and of your device’s platform, and comply with the laws that apply to you. Claims about the Game, such as defects, legal compliance or consumer protection, should be sent to us (support@tefs.com).

10. No warranties

The Game is provided “as is” and “as available”. As far as the law allows, we do not promise that the Game will meet your expectations, run without interruption or errors, or keep your progress safe. This does not affect rights that the law gives you as a consumer and that cannot be excluded.

11. Limit of liability

As far as the law allows, we are not liable for indirect or consequential loss, for loss of virtual items, progress or data in the Game, or for anything that happens through third-party ads, services or devices. Nothing in these terms limits liability that cannot be limited by law, for example for fraud, or for death or personal injury caused by negligence, or your statutory rights as a consumer.

12. Ending your use

You can stop using the Game at any time by uninstalling it. We may suspend or end your use of the Game if you seriously or repeatedly break these terms. Sections that by their nature should continue (for example 3, 4, 10, 11 and 14) continue after that.

13. Changes to these terms

We may change these terms, for example when the Game or the law changes. The current version is always at the address where you are reading this, with its effective date. If a change is important, we will say so in the Game or on this page. If you keep using the Game after a change takes effect, you accept the new terms, as far as the law allows; if you do not agree, stop using the Game.

14. Governing law

These terms and any dispute about the Game are governed by the laws of Cyprus. If you are a consumer in the European Union, the United Kingdom or elsewhere with mandatory consumer protection, you keep the protection that the law of your country of residence gives you, and you may bring a claim in the courts of your country as well. Otherwise the courts of Cyprus have jurisdiction.
