Please read this Agreement carefully before accessing or using the Website and App. By accessing or using any part of the web site, you agree to become bound by the terms and conditions of this agreement.

Your Wölffapp.com Account and Site.

If you create an Account on the Website or App, you are responsible for maintaining the security of your account, and you are fully responsible for all activities that occur under the account and any other actions taken in connection with it. You must not describe or assign keywords to your account in a misleading or unlawful manner, including in a manner intended to trade on the name or reputation of others, and Wölff may change or remove any description or keyword that it considers inappropriate or unlawful, or otherwise likely to cause Wölff liability. You must immediately notify Wölff of any unauthorized uses of your account or any other breaches of security. Wölff will not be liable for any acts or omissions by You, including any damages of any kind incurred as a result of such acts or omissions.

Responsibility of Contributors.

If you operate an account, comment on an image or discussion thread, post material to the Website or App, post links, or otherwise make (or allow any third party to make) material available by means of the Website or App (any such material, “Content”), You are entirely responsible for the content of, and any harm resulting from, that Content. That is the case regardless of whether the Content in question constitutes text, graphics, an audio file, or computer software. By making Content available, you represent and warrant that:

  • the downloading, copying and use of the Content will not infringe the proprietary rights, including but not limited to the copyright, patent, trademark or trade secret rights, of any third party;
  • if your employer has rights to intellectual property you create, you have either (i) received permission from your employer to post or make available the Content, including but not limited to any software, or (ii) secured from your employer a waiver as to all rights in or to the Content;
  • you have fully complied with any third-party licenses relating to the Content, and have done all things necessary to successfully pass through to end users any required terms;
  • the Content does not contain or install any viruses, worms, malware, Trojan horses or other harmful or destructive content;
  • the Content is not spam, is not machine- or randomly-generated, and does not contain unethical or unwanted commercial content designed to drive traffic to third party sites or boost the search engine rankings of third party sites, or to further unlawful acts (such as phishing) or mislead recipients as to the source of the material (such as spoofing);
  • the Content is not pornographic, does not contain threats or incite violence, and does not violate the privacy or publicity rights of any third party;
  • your Account is not getting advertised via unwanted electronic messages such as spam links on newsgroups, email lists, other blogs and web sites, and similar unsolicited promotional methods;
  • your Account is not presented in a manner that misleads your readers into thinking that you are another person or company; and
  • you have, in the case of Content that includes computer code, accurately categorized and/or described the type, nature, uses and effects of the materials, whether requested to do so by Wölff or otherwise.

You also give other Wölff users permission to share your public Content in their discussion groups and presentations; the metadata and appropriate credit automatically remains with the original Content, even when other users make use of it.

If you delete Content, Wölff will use reasonable efforts to remove it from the Website and App, but you acknowledge that caching or references to the Content may not be made immediately unavailable.

Without limiting any of those representations or warranties, Wölff has the right (though not the obligation) to, in Wölff's sole discretion (i) refuse or remove any content that, in Wölff's reasonable opinion, violates any Wölff policy or is in any way harmful or objectionable, or (ii) terminate or deny access to and use of the Website or App to any individual or entity for any reason, in Wölff's sole discretion. Wölff will have no obligation to provide a refund of any amounts previously paid.

Payment and Renewal. General Terms.

Optional paid services.

(a) Individual Subscribers. By selecting a pay account ("Upgrade") you agree to pay Wölff the annual subscription fees indicated for that service. Payments will be charged on a pre-pay basis on the day you sign up for an Upgrade and will cover the use of that service for the annual subscription period as indicated. Upgrade fees are not refundable.

(b) Institutional Subscribers ("enterprise accounts"). Enterprise accounts are charged for users who register either on the web or on their mobile devices with the institution's designated email suffix (e.g. "@yale.edu"). Billing is pro-rated every month based strictly on volume of users. That means you will never be charged for inactive accounts. We charge only when users confirm that their institutional email accounts are fully functional. If an email address is defunct or inactive, a new user will not receive this message and will therefore be unable to register. For your additional comfort, we ask that users confirm their email address twice every year to ensure the continued validity of their affiliation. Finally, as the administrator to your institutional account, you can manage an up-to-date list of your registered members.

(c) Wölff complies with internet sales tax and therefore reserves the right to add the appropriate sales tax to subscription-related fees, when applicable. All eligible nonprofit institutions are exempt from NY State sales tax; to comply with this exemption, VRC's / administrators of institutional accounts must fill out the New York state and Local Sales and Use Tax Exemption Certificate (ST-119.1 or in certain cases ST-120) and email a copy to sales@wolffapp.com within 3 months of initial subscription. Forms can be made available by calling the New York State Tax Office at 518-485-2889.

Automatic Renewal.

Unless you notify Wölff before the end of the applicable subscription period that you want to cancel an Upgrade or Enterprise Account, your subscription will automatically renew and you authorize us to collect the then-applicable annual subscription fee for such Upgrade (as well as any taxes) using any credit card or other payment mechanism we have on record for you. Upgrades can be canceled at any time in the Account Settings section of your site’s dashboard. Enterprise Accounts must be cancelled by contacting Customer Service.

Responsibility of Website Visitors.

Wölff has not reviewed, and cannot review, all of the material, including computer software, posted to the Website or App, and cannot therefore be responsible for that material’s content, use or effects. By operating the Website, Wölff does not represent or imply that it endorses the material there posted, or that it believes such material to be accurate, useful or non-harmful. You are responsible for taking precautions as necessary to protect yourself and your computer systems from viruses, worms, Trojan horses, and other harmful or destructive content. The Website or App may contain content that is offensive, indecent, or otherwise objectionable, as well as content containing technical inaccuracies, typographical mistakes, and other errors.

You are responsible for taking precautions as necessary to protect yourself and your computer systems from viruses, worms, Trojan horses, and other harmful or destructive content.

If you believe that material located on or linked to by Wölff violates your copyright, you are encouraged to notify Wölff in accordance with Wölff’s Digital Millennium Copyright Act (“DMCA”) Policy. Wölff will respond to all such notices, including as required or appropriate by removing the infringing material or disabling all links to the infringing material. Wölff will terminate a visitor’s access to and use of the Website or App if, under appropriate circumstances, the visitor is determined to be a repeat infringer of the copyrights or other intellectual property rights of Wölff or others. In the case of such termination, Wölff will have no obligation to provide a refund of any amounts previously paid to Wölff.
