Art of Problem Solving Terms of Service

Terms and Conditions of Art of Problem Solving Community Membership

The following are the terms and conditions of this Agreement between the User and AoPS Incorporated (AoPS).

    1. AoPS Services - AoPS currently provides users with access to various on-line resources, including shopping, classes, forums and chat rooms (Service). This Agreement applies to these Services and to new or enhanced Services unless explicitly stated otherwise. The Service is provided "AS-IS" and AoPS assumes no responsibility for the timeliness, deletion, mis-posting, mis-delivery or failure to store any user communications or personalization settings. Some Services, such as classes, require the User to pay for their use.

    2. Registration - Registration is required for use of certain Services. When registration is required, the User agrees to provide all required information accurately. AoPS reserves the right to suspend or terminate Services to any User, if AoPS in its sole discretion determines that the registration information is not accurate and complete. If you are under eighteen (18) years of age, you may register only with the involvement and consent of a parent or legal guardian, or at the direction of a representative from your school.

    3. AoPS Privacy Policy - The AoPS Privacy Policy is contained in a separate document and is hereby made an integral part of this Agreement.

    4. User Account, Username, and Password - During registration the User selects a Username and Password. The Username is also used as an onscreen name. It should be a pseudonym and not your real name. The User is responsible for retaining the Username and password in confidence. The User is responsible for all activities that occur using this Username and password. The User agrees to immediately notify AoPS of any unauthorized use of the User Name and password, and to log out after each session.

    5. User Conduct - You understand that all information, data, text, software, music, sound, photographs, graphics, video, messages, or other materials (Content), whether publicly posted or privately transmitted, are the sole responsibility of the person from which such Content originated. This means that the User, and not AoPS, is entirely responsible for all Content that the User uploads, posts, e-mails, transmits, or otherwise makes available via the Services. While AoPS makes reasonable efforts not to allow offensive, indecent, or objectionable material on this site, by using the Services, the User may be exposed to Content that is offensive, indecent or objectionable. Under no circumstances will AoPS be liable in any way for any Content, including, but not limited to, any errors or omissions in any Content, or for any loss or damage of any kind incurred as a result of the use of any Content posted, e-mailed, transmitted, or otherwise made available via the Service.

    The User agrees as follows:

    a. not to harm minors or cause minors to be harmed in any way;

    b. not to forge headers of postings, e-mails, or otherwise manipulate identifiers in order to disguise the origin of any Content transmitted through the Services;

    c. not to impersonate any person or entity, including, but not limited to, an AoPS employee, forum moderator, guide or guest, or falsely state or otherwise misrepresent your affiliation with any person or entity;

    d. not to upload, post, e-mail, transmit, or otherwise make available any Content that is unlawful, harmful, threatening, abusive, harassing, tortuous, defamatory, vulgar, obscene, libelous, invasive of another's privacy, hateful, or racially, ethnically or otherwise objectionable;

    e. not to upload, post, e-mail, transmit, or otherwise make available any Content that you do not have a right to make available under any law or under contractual or fiduciary relationships (such as inside information, proprietary and confidential information learned or disclosed as part of employment relationships or under nondisclosure or confidential disclosure agreements);

    f. not to upload, post, e-mail, transmit, or otherwise make available any information that you consider confidential in nature, which posting may cause you or any third party to lose rights to the intellectual property associated with the information;

    g. not to upload, post, e-mail, transmit, or otherwise make available any Content that infringes any patent, trademark, trade secret, copyright, or other proprietary and lawful rights of any party;

    h. not to upload, post, e-mail, transmit, or otherwise make available any unsolicited or unauthorized advertising, promotional materials, "junk mail," "spam," "chain letters," "pyramid schemes," or any other form of solicitation. You understand that such postings may violate laws of various jurisdictions, and that you may be subject to prosecution or to civil suit;

    i. not to intentionally or unintentionally violate any local, state, national, or international law;

    j. not to "stalk" or otherwise harass another; or collect or store personal data about other users;

    k. to upload, post, e-mail, transmit, or otherwise make available only material which the User has created and to which the User owns the copyrights; and

    l. to report any violations of the above immediately to AoPS.

    6. Integration - This Agreement, together with any other documents referenced herein constitutes the entire agreement between the parties and supersedes all previous agreements, promises, proposals, representations, understandings, and negotiations, whether written or oral, between the parties respecting the subject matter hereof.

    7. License to Copy and Distribute User Material - AoPS does not claim ownership of the Content you submit or make available for inclusion on the Service. However, with respect to Content you submit or make available for inclusion on publicly accessible areas of the Service, the User hereby grants a non-exclusive, perpetual, irrevocable, fully sub-licensable, world-wide, fully-paid-up license which allows AoPS to use, distribute, reproduce, modify, adapt, publish, translate, publicly perform, and publicly display such Content (in whole or in part) and to incorporate such Content into other works in any format or medium now known or later developed.

    8. Governing Law - This Agreement shall be governed by the laws of the State of California without regard to any conflicts of law provisions.

    9. Jurisdiction and Venue - The parties agree to submit exclusively to the personal jurisdiction of a proper court located only in the County of San Diego, State of California. Both parties agree that venue is proper in the County of San Diego, State of California. The parties agree to waive any defenses based on venue, inconvenience of forum, the lack of personal jurisdiction, and the adequacy of service of process (as long as the party was at least notified by the email address provided) in any suit or action brought in the State of California.

    10. Time Limitations - Regardless of any statute or law to the contrary the parties agree that any claim or cause of action arising out of this Agreement or related to the Services must be filed within one year after such claim or cause of action arises or forever be barred.

    11. Waiver - The failure of either party to exercise or enforce any right or provision of this Agreement shall not constitute a waiver of such right or provision.

    12. Enforceability - In the event any one or more of the provisions of this Agreement shall for any reason be held to be invalid, illegal, or unenforceable, the remaining provisions of this Agreement shall be unimpaired, and the invalid, illegal, or unenforceable provision shall be replaced by the provision which, being valid, legal, and enforceable, comes closest to the intention of the parties underlying the invalid, illegal, or unenforceable provision.

    13. Warranties - AoPS makes no warranty that: (a) the Services will meet your requirements, (b) the Services will be uninterrupted, timely, secure, or error-free, (c) the results that may be obtained from the use of the Services will be accurate or reliable, (d) the quality of any products, Services, information, or other material purchased or obtained by you through the Services will meet your expectations, and (e) any errors in the software will be corrected.


    14. Assignments - Neither party may assign or delegate any or all of its rights or its duties or obligations hereunder without the consent of the other party, which consent shall not be unreasonably withheld or delayed; provided, however, that either party may assign this Agreement, without the need to obtain consent of the other party, to an affiliate of such party or to a successor in interest to substantially all of the business of that party to which this Agreement relates. An assignee of either party authorized hereunder shall be bound by the terms of this Agreement and shall have all of the rights and obligations of the assigning party set forth in this Agreement. An assignment which is in violation of this Agreement is void.

    15. No Construction Against Drafter - If an ambiguity or question of intent arises with respect to any provision of this Agreement, the Agreement will be construed as if drafted jointly by the parties and no presumption or burden of proof will arise favoring or disfavoring either party by virtue of authorship of any of the provisions of this Agreement.

    16. Force Majeure - Either party shall be excused from performance and shall not be liable for any delay in whole or in part, caused by the occurrence of any contingency beyond the reasonable control either of the excused party or its subcontractors or suppliers including, but not limited to, war, sabotage, insurrection, riot or other act of civil disobedience, act of public enemy, failure or delay in transportation, act of any government or any agency or subdivision thereof affecting the terms hereof, accident, fire, explosion, flood, severe weather or other act of God, or shortage of labor or fuel or raw materials.

    17. Attorneys' Fees - If any legal action is brought to construe or enforce any provision of this Agreement, the prevailing party shall be entitled to receive its reasonable attorneys' fees and court costs in addition to any other relief it may receive.
