Brain Puzzle Daily Terms of Use

1. About these terms

These terms govern Brain Puzzle Daily, provided by Blade Planning Co., Ltd. (the Company). Please read these terms before using the app. Applicable Apple, Google and third-party service terms may also apply. These terms do not remove rights that applicable law gives you.

2. Users and parents

The app is a general-audience puzzle game for all ages. Minors should ask a parent or legal guardian to review these terms and the privacy notice and obtain any required consent. Follow the age rating shown by your store and your device’s parental controls.

Self-declared age groups control advertising, not access to the basic games. We do not request ads for users under 16 or users who have not selected an age group. This is not identity verification and does not establish a minimum age for playing.

3. Games and charges

The app provides math, memory, shape and number puzzles, daily challenges and local records. Basic games are free and require no account. The initial version has no in-app purchases. You are responsible for device and connectivity charges.

The app is for entertainment. It is not a medical, diagnostic or treatment service and does not guarantee cognitive benefits.

4. Advertising and optional rewards

Google AdMob ads may be available depending on your settings and applicable consent choices. Basic games remain available with ads disabled or unavailable.

Rewarded ads are voluntary. A reward is granted only when the advertising SDK confirms completion. The current reward is a separate 30-second practice round; it does not increase normal scores. Leaving early, delivery or connectivity problems may prevent completion from being confirmed. If reward storage fails, the app offers a save retry without requiring another ad view. Rewards cannot be redeemed for money or goods.

Do not manipulate ads or automate ad impressions, clicks or viewing. Advertised services are subject to their providers’ own terms.

5. Local records

Scores, settings, daily results, ad controls and rewards are stored locally. Unfinished games and incomplete three-game daily challenges are not completion records. An interrupted daily challenge cannot be resumed after restarting the app.

Changes to dates or time zones, OS behavior, deleting the app or its data, device failure and similar events can change or remove records. OS backup restoration may restore older data. Game records are not sent to Company servers, so we cannot restore lost local records from a server. See the individual privacy notice and Company privacy policy for data handling.

6. Misuse and intellectual property

Do not break the law, infringe others’ rights, gain unauthorized access, manipulate the app, scores, rewards or ads, or interfere with operation.

The Company or relevant rights holders own the app’s software, designs, text and artwork. Copying or redistribution beyond permissions provided by law or the rights holder is prohibited. Open-source and third-party SDK components have their own licenses, available from the app.

7. Changes and ending use

Features may change or be temporarily unavailable for maintenance, security, bug fixes or changes in laws and distribution platforms. Except in urgent circumstances, significant changes or discontinuation will be announced in the app or on the Company website in advance.

You may stop using the app and delete it or its local data at any time. See the privacy notice for OS backups and data already processed by third parties.

8. Responsibility

We work to correct problems but do not promise uninterrupted or error-free operation or support for every device and OS.

Where damage is attributable to the Company, we are responsible in accordance with applicable law. These terms do not exclude or limit liability for intentional misconduct, gross negligence, or liability that consumer protection law does not permit us to exclude or limit.

9. Changes to terms and disputes

Changes to these terms, their effective date and relevant information will be announced in the app or on the Company website. We will obtain renewed consent when the law requires it.

Japanese law governs these terms, without taking away mandatory consumer protection rights that apply where you live. The parties will seek to resolve disputes; court jurisdiction is determined by applicable law.
