Terms of Use

By accessing or using the Service, you express your irrevocable acceptance of these Terms and the Privacy Policy, which is incorporated by reference. You may use the Service only if you are capable, under the law of your country of residence, of entering into binding contracts. For users under 18, you represent that you have authorization from a legal guardian and use the Service under their supervision. If you accept these Terms on behalf of a company or other legal entity, you expressly represent that you have authority to bind it, and 'you' will refer to both the natural person and the legal entity represented. Acceptance of these Terms may be expressed by any unequivocal act, including mere access to the Service, account creation, checking an acceptance checkbox, completing a test, or making a payment.

The Service offers online tests for personality, self-knowledge, compatibility, and derived products (including current or future premium reports), exclusively for the purposes of self-reflection, entertainment, and personal development. The Service is provided 'AS IS' and 'AS AVAILABLE'. We reserve the right to modify, suspend, discontinue, or restrict, in whole or in part, any feature or the entire Service, at any time, with or without notice, without liability of any kind. We do not guarantee continuous availability, freedom from errors, accuracy or precision of results, compatibility with any specific device, browser, or software, nor freedom from interruptions for maintenance, updates, or due to external provider failures, malicious access, accidents, fortuitous events, or force majeure.

Some features require account registration. By registering, you agree to provide truthful, current, accurate, and complete information, and to keep it updated. You are solely responsible for: (a) maintaining the absolute confidentiality of your credentials; (b) restricting access to your account and devices; (c) all activity carried out through your account, whether authorized or not. Notify us immediately at contact@bigduckai.com of any unauthorized use, suspicion of compromise, or loss of credentials. We are NOT liable for loss, damages, or harm resulting from misuse of credentials, the User's failure to protect their account, or sharing of access. We reserve the right to suspend, restrict, or terminate accounts at our sole discretion in case of violation of these Terms, suspicion of fraud or abuse, activity inconsistent with the nature of the Service, prolonged inactivity, request from a competent authority, or for any reasonable reason, with or without prior notice.

You agree to use the Service only for lawful, personal, non-commercial purposes and in strict compliance with these Terms, applicable law, and good morals.

We reserve the right to investigate, monitor, and take any measures we deem appropriate in case of suspected violation, including cooperation with authorities, without prior notice.

YOU UNDERSTAND, ACCEPT, AND EXPRESSLY AGREE THAT: (a) the tests offered are NOT clinical instruments, do NOT constitute medical, psychiatric, psychological, mental health, or any clinical diagnosis, do NOT replace assessment by a qualified and licensed professional, and must NOT be used as the sole, primary, or even relevant basis for decisions regarding health, career, employment, relationships, legal matters, finance, parenting, or any other personally relevant matters; (b) results are generated from public-domain psychometric instruments, heuristic models, generative artificial intelligence, or combinations of these techniques, and may contain inaccuracies, statistical errors, cultural biases, limitations inherent to self-report, and deviations from any objective reality; (c) results reflect self-reported patterns at a specific moment and must NOT be interpreted as a definitive, permanent, objective, or scientifically proven description of your personality, capabilities, traits, disorders, or conditions; (d) any decision made on the basis of results is YOUR SOLE AND COMPLETE RESPONSIBILITY; (e) You BigDuckAI is NOT responsible for misinterpretation, misuse, emotional harm, mistaken decisions, financial losses, or consequences of any nature arising from decisions made based on results, even if serious or irreversible; (f) if you are experiencing psychological distress, suicidal ideation, self-harm, emotional crisis, or any risk situation, do NOT rely on this Service as a form of help.

Applicable taxes are the User's sole responsibility, except where expressly collected at source by us or our processors.

You agree to indemnify, defend, and hold harmless You BigDuckAI, its partners, directors, employees, service providers, agents, affiliates, and licensors (collectively, 'Indemnified Parties') from and against any claims, demands, actions, lawsuits, losses, damages, obligations, costs, fines, and expenses, including reasonable attorneys' fees and court costs, arising from or related to: (a) your access to or use of the Service in violation of these Terms; (b) violation of third-party rights by your conduct, omission, or User Content; (c) violation of applicable laws, regulations, or court orders; (d) decisions made on the basis of test results, with or without our guidance; (e) false, incomplete, or misleading statements or information provided by you; (f) willful or negligent acts or omissions on your part; (g) chargebacks or payment disputes initiated in violation of these Terms.

We reserve the right to modify, supplement, update, or replace these Terms at any time, at our sole discretion, to reflect changes in the Service, practices, partners, or legal requirements. Changes take effect on the 'Last updated' date at the top of this page. Material changes will be flagged via prominent notice in the Service or email to account holders at least 30 days before they take effect, except where the law requires a different period or in cases of urgency (including security risks or regulatory requirements) where immediate effect is permissible. CONTINUED USE OF THE SERVICE AFTER THE EFFECTIVE DATE CONSTITUTES IRREVOCABLE ACCEPTANCE OF THE CHANGES. If you do not agree, you must discontinue use before the effective date. The most current version of the Terms supersedes prior versions and any communications to the contrary.

These Terms are governed by and construed in accordance with the laws of the Federative Republic of Brazil, excluding conflict-of-laws rules and the United Nations Convention on Contracts for the International Sale of Goods, except for consumer protections deemed mandatory and that cannot be displaced by the law of the User's country of habitual residence. For any dispute, controversy, or claim arising from or relating to these Terms, the Service, or the processing of data, the courts of the District of São Paulo, State of São Paulo, Brazil are designated as competent, with express waiver of any other, however privileged. For consumers residing in the European Union, the United Kingdom, Switzerland, or countries where mandatory consumer protection law allows, the right to bring action in the consumer's domicile is preserved as required by law. Before any legal action, the parties will use reasonable efforts to resolve amicably through direct negotiation, with formal notice by email to contact@bigduckai.com and a minimum 30-day period to attempt resolution, except in cases of urgency or where injunctive relief is required.

(a) SEVERABILITY: if any provision of these Terms is held invalid, illegal, unenforceable, or inapplicable by a competent authority, the remaining provisions will continue in full force; the affected provision will be construed to reflect, to the maximum extent possible, the original intent of the parties, and may be replaced by a valid provision producing equivalent effect. (b) NO WAIVER: tolerance, failure, or delay in enforcing any provision does not constitute waiver of the corresponding right, which may be exercised at any time. (c) ASSIGNMENT: you may not assign, transfer, or delegate these Terms or any rights and obligations without our prior written authorization; we may freely assign or transfer, in whole or in part, by mere notice. (d) ENTIRE AGREEMENT: these Terms, the Privacy Policy, and other notices published in the Service constitute the entire agreement between the parties, superseding any prior or contemporaneous understandings, proposals, communications, or contracts on the same subject. (e) ELECTRONIC COMMUNICATIONS: you expressly agree to receive communications in electronic form (email, in-Service notifications), with legal effects equivalent to physical or registered form. (f) LANGUAGES: the English version of these Terms is provided for convenience; the Brazilian Portuguese version prevails over translations in case of divergence or ambiguity, except where otherwise required by mandatory consumer law. (g) FORCE MAJEURE: neither party shall be liable for non-performance arising from facts beyond its reasonable control, including fortuitous events, force majeure, government action, war, epidemic, telecommunications or power provider failure, cyberattack, or strike.

(i) NO PARTNERSHIP: nothing in these Terms creates a partnership, joint venture, mandate, agency, representation, or employment relationship between the parties.
