By downloading, installing, or playing Brainclash ("the Game", "we", "us"), you agree to be bound by these Terms of Use and by our Privacy Policy. If you do not agree, please do not use the Game.
2. Your Account
You sign in using a Google or Apple account through Firebase Authentication. You are responsible for maintaining the security of your sign-in credentials.
Each player has a unique username. Usernames must not be offensive, misleading, or impersonate others. Changing your username costs in-game currency.
You are responsible for all activity that occurs under your account.
3. Gameplay Rules
Matches are asynchronous and turn-based. Challenge invitations remain valid for 24 hours; if not accepted in time, they expire.
Each player must complete their turn within 24 hours. If you do not play your turn in time, you receive a score of zero for that round and the match continues. If you fail to pick a category in time, the system picks a random category and you receive zero for that round.
Each question has a time limit. If the timer runs out, the answer is counted as incorrect. Answer times are measured by the server.
Both players answer the same questions in each round to ensure fairness. Only one answer per question is accepted.
Round and match results are determined by correctness first; speed is used only as a tie-breaker.
Matches against the computer are a separate mode: they award no XP or currency and keep separate statistics.
4. Virtual Currency and In-App Purchases
Brainclash offers a virtual in-game currency that can be earned through optional rewarded ads and the daily bonus wheel, or purchased with real money through the app store.
Currency can be spent on in-game helpers (question swap, remove two wrong answers, extra time), sending match challenges, changing your username, and temporarily removing interstitial ads.
Virtual currency has no real-world monetary value, is non-transferable, cannot be exchanged for cash, and may not be sold or traded outside the Game.
All purchases are processed by the Apple App Store or Google Play and are subject to their terms. Except where required by law or by the applicable app store policy, purchases are final and non-refundable.
Winning matches does not award currency. This is an intentional design decision to keep the game fair.
5. Fair Play and Prohibited Conduct
You agree not to:
Cheat, exploit bugs, or use any modified client, automation tool, script, or third-party software to gain an advantage or interfere with the Game.
Attempt to tamper with, reverse-engineer, or bypass the Game's server-side validation, scoring, timing, or anti-cheat systems.
Collude with other players or share answers to manipulate match results.
Harass, abuse, threaten, or spam other players, including through the chat feature.
Send offensive, unlawful, or inappropriate content in messages or usernames.
Create accounts by automated means or use another person's account without permission.
All game logic is validated server-side. We reserve the right to suspend or permanently terminate accounts that violate these rules, including forfeiture of virtual currency and purchases associated with the violating account.
6. Chat and User Content
You are solely responsible for the messages you send. Do not share personal information of others or content that is illegal, hateful, or harassing.
We provide blocking and reporting tools and may review reported content and take action, including warnings, chat restrictions, or account termination.
7. Advertising
The Game displays optional rewarded ads and automatic interstitial ads between rounds. Purchasing the ad-removal option removes interstitial ads for the purchased period only; optional rewarded ads always remain available as a way to earn currency.
8. Availability and Changes to the Game
We strive to keep the Game available at all times but do not guarantee uninterrupted service. Maintenance, updates, or technical issues may cause temporary downtime.
We may add, change, balance, or remove features, categories, questions, prices, timers, and rewards at any time to improve the Game.
We may discontinue the Game or any part of it. Where reasonably possible, we will provide advance notice of permanent discontinuation.
9. Intellectual Property
The Game, including its name (Brainclash / صراع العقول), design, questions, graphics, and software, is owned by us or our licensors and is protected by intellectual property laws. You are granted a limited, personal, non-exclusive, non-transferable license to play the Game for private, non-commercial use. You may not copy, distribute, modify, or create derivative works from the Game without our written permission.
10. Disclaimer and Limitation of Liability
The Game is provided "as is" and "as available" without warranties of any kind, whether express or implied. To the maximum extent permitted by law, we shall not be liable for any indirect, incidental, special, or consequential damages, or for loss of data, virtual currency, or progress, arising out of or related to your use of the Game. Nothing in these terms excludes liability that cannot be excluded under applicable law.
11. Termination
You may stop using the Game at any time and may request account deletion. We may suspend or terminate your access if you violate these Terms. Upon termination, your license to use the Game ends and any unused virtual currency is forfeited without compensation, except where prohibited by law.
12. Changes to These Terms
We may update these Terms of Use from time to time. Material changes will be communicated within the app or on this page, and the "Effective date" above will be updated. Continued use of the Game after changes take effect constitutes acceptance of the updated Terms.
