Terms & Conditions.

You must be at least 13 years of age (or 16 in the European Economic Area) to use the Service. By using Brain Canvas, you represent and warrant that you meet the applicable minimum age requirement and have the legal capacity to enter into a binding agreement.

If you are using the Service on behalf of a business or other legal entity, you represent that you have the authority to bind that entity to this Agreement, in which case "you" refers to both you individually and that entity. If you lack such authority, you may not use the Service on behalf of that entity.

Brain Canvas reserves the right to refuse service to anyone at any time, for any reason consistent with applicable law.

To access most features of the Service, you must register for an account. You agree to provide accurate, current, and complete information during registration and to keep that information up to date.

• One account per person. You may not create multiple accounts to circumvent limits, bans, or quotas. Accounts are non-transferable.
• Credential security. You are responsible for maintaining the confidentiality of your login credentials and for all activity that occurs under your account. Notify us immediately at security@braincanvas.co if you suspect unauthorized access.
• No sharing. You may not share your account credentials with others or allow third parties to access the Service through your account, except as expressly permitted by a team or enterprise plan.
• Accurate information. Providing false, misleading, or fraudulent registration information is grounds for immediate account termination.

Brain Canvas offers subscription tiers with different feature sets, storage limits, and AI token quotas. Current tier details are described on our pricing page and may be updated from time to time with reasonable notice.

Ownership. You retain full ownership of all User Content you create or upload to the Service. Brain Canvas claims no ownership rights over your canvases, notes, files, or other User Content.

License to operate the Service. By submitting User Content, you grant Brain Canvas a limited, non-exclusive, royalty-free, worldwide license to host, store, reproduce, transmit, and display your User Content solely to the extent necessary to provide and improve the Service for you. This license is limited to service delivery and does not include any right to exploit your content commercially or share it with third parties except as described in our Privacy Policy.

Your representations. You represent and warrant that: (a) you own or have the necessary rights to your User Content; (b) your User Content does not infringe any third-party rights; and (c) your User Content complies with these Terms and applicable law.

Brain Canvas provides AI-powered features including insight generation, content summarization, pattern recognition, and suggestions (collectively, "AI Features"). Your use of AI Features is subject to the following terms:

• No training on your content. Brain Canvas does not use your User Content to train AI models, and will not do so without your explicit opt-in consent. AI Features are delivered using Google Cloud's Vertex AI, which processes your User Content as our data processor under the Google Cloud terms and Data Processing Addendum; under those terms, Google does not use your content to train or improve its own models. The provider may retain content for a limited period for abuse detection and to meet its legal obligations. The provider's obligations are governed by its own terms, which Brain Canvas does not control. See section 4 of our Privacy Policy.
• AI outputs are not professional advice. AI-generated content is provided for informational and productivity purposes only. It does not constitute legal, financial, medical, or other professional advice. Do not rely on AI outputs for decisions requiring expert judgment.
• AI outputs may be inaccurate. AI technology can produce incorrect, incomplete, or outdated information. You are solely responsible for evaluating AI outputs before acting on them.
• Token consumption. AI Features consume tokens from your monthly quota. Quotas reset monthly per your billing cycle. Brain Canvas is not obligated to provide additional tokens beyond your tier's monthly allotment.
• AI output ownership. AI-generated content produced in response to your prompts and canvas content belongs to you, subject to any restrictions imposed by applicable law or third-party AI provider terms.
• Prohibited AI use. You may not use AI Features to generate content that is unlawful, harmful, deceptive, or violates these Terms. This includes generating disinformation, illegal content, content that infringes third-party rights, or content that violates our Acceptable Use policy.

Brain Canvas IP. The Service, including all software, algorithms, designs, interfaces, logos, trademarks, and documentation (excluding User Content), is the exclusive property of Brain Canvas, Inc. and its licensors, protected by intellectual property laws worldwide.

License to use the Service. Subject to your compliance with these Terms and payment of applicable fees, Brain Canvas grants you a limited, non-exclusive, non-transferable, revocable license to access and use the Service for your personal or internal business purposes during the term of your subscription.

Restrictions. You may not: (a) copy, modify, or create derivative works of the Service; (b) use Brain Canvas trademarks without express written permission; (c) remove any proprietary notices from the Service; or (d) use the Service to build a competing product.

The Service integrates with or links to third-party services, including AI model providers, cloud infrastructure, and analytics tools. These integrations are subject to the terms and privacy policies of those third parties — see section 06 of our Privacy Policy for the current list of who receives what.

• Brain Canvas is not responsible for the availability, accuracy, or content of any third-party service.
• Your use of third-party services accessed through or in connection with Brain Canvas is at your own risk and governed by the applicable third-party terms.
• We may change or discontinue third-party integrations at any time without notice, though we will endeavor to notify you of material changes that affect core functionality.

Brain Canvas makes no warranties regarding the accuracy, reliability, or completeness of AI-generated content. AI outputs are probabilistic in nature and may contain errors, hallucinations, or outdated information.

Some jurisdictions do not allow the exclusion of implied warranties, so some of the above exclusions may not apply to you.

Brain Canvas's total cumulative liability to you for all claims arising out of or related to these Terms or the Service shall not exceed the greater of: (a) the total fees paid by you to Brain Canvas in the twelve (12) months preceding the claim; or (b) one hundred US dollars (USD $100).

The limitations above apply regardless of the theory of liability (contract, tort, strict liability, or otherwise) and even if Brain Canvas has been advised of the possibility of such damages. Some jurisdictions do not allow these limitations, so they may not apply to you in full.

You agree to defend, indemnify, and hold harmless Brain Canvas, Inc. and its officers, directors, employees, contractors, licensors, and agents from and against any claims, liabilities, damages, judgments, awards, losses, costs, or expenses (including reasonable attorneys' fees) arising out of or relating to:

• Your violation of these Terms or any applicable law or regulation.
• Your User Content or your use of the Service in a manner not authorized by these Terms.
• Your infringement of any third-party intellectual property, privacy, or other rights.
• Any misrepresentation made by you in connection with the Service.

Brain Canvas reserves the right to assume the exclusive defense and control of any matter subject to indemnification by you, at your expense, in which case you agree to cooperate with our defense.

Term. This Agreement is effective from the date you first use the Service and continues until terminated by you or Brain Canvas.

Termination by you. You may cancel your subscription at any time through your account settings or by contacting support@braincanvas.co. Cancellation takes effect at the end of the current billing period; you retain access until then. No refund is issued for the remaining portion of the period.

Termination or suspension by Brain Canvas. Brain Canvas may suspend or terminate your account at any time for any of the following reasons:

• Violation of these Terms, including Acceptable Use policies.
• Non-payment of fees after reasonable notice.
• Conduct that harms other users, third parties, or Brain Canvas's reputation or systems.
• A requirement under applicable law or a court order.

Effect of termination. Upon termination: (a) your license to use the Service immediately ceases; (b) we may delete your account data after the applicable retention period described in our Privacy Policy; (c) outstanding payment obligations survive termination; (d) all provisions of these Terms that by their nature should survive will survive, including IP rights, disclaimers, and dispute resolution.

Data export. You are encouraged to export your User Content before requesting account deletion. We will retain your data for 30 days after account deletion to allow recovery, then permanently delete it.

Governing law. These Terms are governed by and construed in accordance with the laws of the State of Delaware, United States, without regard to its conflict-of-law provisions.

Informal resolution first. Before initiating formal proceedings, you agree to contact Brain Canvas at legal@braincanvas.co and give us 30 days to attempt to resolve the dispute informally. Most concerns can be resolved quickly this way.

Binding arbitration. If informal resolution fails, any dispute, claim, or controversy arising out of or relating to these Terms or the Service shall be resolved by binding individual arbitration administered by the American Arbitration Association (AAA) under its Commercial Arbitration Rules. The arbitration will take place in Delaware. The arbitrator's decision is final and enforceable in any court of competent jurisdiction.

Exceptions. Either party may seek injunctive or other equitable relief in a court of competent jurisdiction to prevent irreparable harm pending arbitration. Claims relating to intellectual property infringement may be brought in court without first pursuing arbitration.

EU/UK users. If you are located in the European Union or United Kingdom, mandatory consumer protection laws of your country of residence may apply and grant you rights that cannot be contractually waived. Nothing in these Terms limits those statutory rights.
