These Terms govern use of YOSHINANI Brick, including its creation, conversion and sharing features (the "Service"), provided by YOSHINANI Inc. ("we" or "us"). By using the Service, you agree to these Terms.
One account is used across creation, conversion and sharing features. Registration is currently for users aged 18 or older and is available with an email address and password or a Google account. You can add passkeys after signing in. You must register accurate, current information and are responsible for protecting your password, Google account, passkey devices and other credentials.
Copyright in creations and other content you post remains with you or the lawful rights holder. You grant us a non-exclusive, royalty-free right to reproduce, display and distribute that content as reasonably necessary to provide, improve and promote the Service. You may not post content that infringes third-party rights or violates public order and morals.
AI features such as design assistance, concept generation and photo conversion are provided using models and APIs operated by external generative-AI providers we select, and the suggestions, images and data they produce are reference material. Text, images, 3D data and similar input you provide are sent to those providers, including providers located outside Japan, to the extent needed to perform the requested feature; see the Privacy Policy for details. We do not guarantee their accuracy, legality or freedom from third-party rights. You are responsible for deciding whether and how to use them. Credits consumed by an operation are returned when no usable result is delivered because of an external processing failure, empty output or invalid output format.
To the extent of the rights we hold, we license you to use output generated for you through the Service's AI features, including reproducing, modifying, distributing and publishing it. Whether commercial use is permitted depends on the conditions of your plan as shown on the pricing page. Because of how generative AI works, similar or identical output may be produced for other users, so the rights you receive are non-exclusive. If you use output commercially, you are responsible for confirming that it does not infringe third-party trademark, design or copyright. The Service is not affiliated with, sponsored by or endorsed by any brick toy manufacturer.
Some features require a monthly auto-renewing Creator or Pro plan or one-time Brick credits. Tax-inclusive prices, credit amounts, payment timing and availability are shown on the pricing page, checkout and legally required commerce disclosure. Pro users receive 5% bonus credits when buying a pack. Revised prices apply to new purchases as displayed; we give advance notice before applying changes to an existing subscription.
Purchased credits and the related Pro bonus expire 180 days after purchase. Free has no included allowance credits. Paid-plan allowance credits are granted after payment, expire at the end of the applicable billing period and do not roll over. Free promotional balances issued automatically for registration or migration before the August 4, 2026 policy change have ended, and unused amounts expire. Purchased credits, paid-plan allowances, individual adjustments and technical refunds are not affected by this change. Credits may be used only for eligible Service features and cannot be exchanged for cash, transferred to another person or moved between accounts. Credits are generally consumed from the lot expiring first.
Creator and Pro renew monthly unless you stop the next renewal from Plan and billing by the day before the renewal date. Access continues through the current billing period and no prorated refund is provided. Completed digital-service purchases are non-refundable for change of mind except where required by law. Credits consumed by an operation are returned when no usable result is delivered because of an external processing failure, empty output or invalid output format.
You may delete your account from Account settings after any paid subscription period ends. Deletion removes or invalidates your profile, posts, projects, credentials and remaining credits and cannot be undone. Payment and transaction records required by law or accounting rules may be retained for the required period after being disconnected from your account.
You may not harass other users, send spam, gain unauthorized access, distribute malware, reverse engineer, disrupt or abuse the Service, or violate laws or public order. We may suspend or permanently terminate accounts for violations without prior notice where appropriate.
The Service is provided as is. We do not guarantee the accuracy, completeness, fitness for a particular purpose or non-infringement of generated output. Except for willful misconduct or gross negligence, our liability is limited to direct and ordinary damages and the amount you paid for the Service in the 12 months preceding the loss. This limitation does not apply where prohibited by mandatory consumer law.
We may update these Terms where the change benefits users generally or is reasonable and consistent with the purpose of the agreement. We will announce the revised terms and effective date in advance through the Service, email or another appropriate method as required by law.
We may temporarily suspend the Service for maintenance, incidents, natural disasters or other unavoidable circumstances. If an external generative-AI provider or other external service we rely on changes its specifications or terms, discontinues its service, or another cause beyond our reasonable control arises, we may change or suspend the scope and availability of AI features and the credit cost of the affected operations. We will announce any increase in credit cost through the Service before it takes effect. If we terminate the Service or a material paid feature, we will provide reasonable advance notice and handle unused paid credits in accordance with applicable law.
These Terms are governed by Japanese law. To the extent permitted by law, disputes are subject to the exclusive first-instance jurisdiction of the district court having jurisdiction over our registered office. Contact us through the Service contact form regarding these Terms, payments or credits.
