1 Membership

The Service that CAEplex provides consists of a Software-as-a-service platform which may be used to model physical processes and/or systems that might have engineering applications (see “CAEplex Service” below). In order to use the services provided by this website, you (“The Customer”) will need to register as a user by creating an account at https://www.caeplex.com (“User Account”) and provide your full name, a valid email address and a password (“Login Credentials”). The collection and use of Account Information is governed by our privacy policy. After validation of the email address, a User Account will be created. Upon the making of these Terms and Conditions, Seamplex agrees to enable the Customer to use the services. By default, any new account will be a “Free” account, meaning that access to the services listed as “Free plan” in the plans and pricing page will be provided. Usage of the services under the terms of any other plan will be subject to a paid subscription.

Your standard non-free CAEplex membership may nevertheless start with a 14-day Trial free of charge that is intended to allow new members and certain former members to try the full service. At any time, from any account in the “Free” plan you can start a Trial period of a “Standard” plan for 14 days, or as otherwise specified during sign-up. Trial eligibility is determined by Seamplex at our sole discretion and we may limit eligibility to prevent Trial abuse. We reserve the right to revoke access to the Trial and put your account on hold in the event that we determine that you are not eligible. We may use information such as personal information, device ID, originating IP or an account email address used with an existing or recent CAEplex membership to determine eligibility. For combinations with other offers, restrictions may apply.

After the Trial period, you have to provide a current, valid, accepted method of payment, which you may update from time to time (“Payment Method”) to continuing using the non-free CAEplex service. Otherwise, your account will be downgraded back to the “Free” plan and you cannot start another Trial.

If you opt to subscribe to a paid membership, you will be charged the amount corresponding to the selected plan at the time of the subscription. Your CAEplex membership will continue month-to-month until terminated. Unless you cancel your membership before your monthly billing date, you authorize us to charge your next month’s membership fee to your Payment Method (see “Cancellation” below). You can find specific details regarding your CAEplex membership by logging into our website and going to the “Account” section.

You must not create user accounts through unauthorized means, including but not limited to, by using a script, bot, spider, crawler, or scraper, or other automated methods. These accounts will be removed upon detection. When you choose to provide information to the services, you agree that all information you provide to register with the services and to create your account shall be truthful and accurate, and you agree to update your information as necessary to ensure that it remains truthful and accurate. Any account containing false information will be removed upon detection. You understand and agree that you are responsible for maintaining the confidentiality and security of your Login Credentials, and that you are solely responsible for all activities that occur on or through your User Account. You agree to notify us immediately if you suspect any unauthorized use of your User Account or access to your password. You agree that you will not solicit, collect or use the login credentials of other users. You also acknowledge that the Internet may be subject to breaches of security and that the submission of data or other information (“User Submission”) may not be secure. See our security measures for more details.

2 Billing

The membership fee for the CAEplex service and any other charges you may incur in connection with your use of the Service, such as taxes and possible transaction fees, will be charged on a monthly basis to your Payment Method on the calendar day corresponding to the commencement of the paying portion of your membership. In some cases your payment date may change, for example if your Payment Method has not successfully settled or if your paid membership began on a day not contained in a given month.

You can change your Payment Method by logging into our website and going to the “Account” section. If a payment is not successfully settled, due to expiration, insufficient funds, or otherwise, and you do not change your Payment Method or cancel your account, we may suspend your access to the service until we have obtained a valid Payment Method. When you update your Payment Method, you authorize us to continue charging the updated Payment Method, and you remain responsible for any uncollected amounts. This may result in a change to your payment billing dates. For some Payment Methods, the issuer of your Payment Method may charge you certain fees, such as a foreign transaction fee or other fees relating to the processing of your Payment Method. Local tax charges may vary depending on the Payment Method used. Check with your Payment Method service provider for details.

We may change our service plans and the price of our service from time to time; however, any price changes or changes to our service plans will apply to you no earlier than 30 days following notice to you.

3 Cancellation

You can cancel your CAEplex membership at any time, and you will continue to have access to the CAEplex service through the end of your monthly billing period. If you cancel your membership, your account will automatically be converted back to a “Free” account at the end of your current billing period. If you are not satisfied with the service, you are entitled to a refund corresponding to the last billing period provided you explain the reasons the service did not satisfy your needs.

In the event that your User Account is canceled or a non-free Account in converted back into a free account, the account’s data will be stored for 30 days and afterward deleted as part of the cancellation process.

We reserve the right, at any time, in our sole discretion, to disable any user Login Credentials, whether chosen by you or provided by us, and to suspend or terminate your User Account or otherwise deny you access, without notice and without liability, and with or without cause, including if we believe you are in breach of these Terms and Conditions. Seamplex will not necessarily provide advance warning of such termination or suspension. We reserve the right to refuse provision of or access to the Service to anyone for any reason and at any time. Any termination or suspension of the Service may result in the deactivation or deletion of your User Account or access to your account, and may also result in the forfeiture and relinquishment of all content in your account, as determined by us in our sole discretion. Verbal, physical, written or other abuse (including threats of abuse or retribution) of any customer, employee, member, or officer will result in immediate account termination.

4 CAEplex Service

Seamplex grants you the use of a Software-as-a-service application in the form of a web-based platform named CAEplex which can be accessed at https://www.caeplex.com. This platform is a front-end for a number of software back-ends aimed at solving equations that model physical processes and/or systems which might have engineering applications. Seamplex is thus providing a technical construct for use. The usage of the Service implies using data that the Customer uploads to the User Account several kind of data, including CAD files, parameters, settings, and other necessary information. The data transmitted by the Customer may be forwarded by Seamplex to other computers—always in an end-to-end encrypted form using TLS over the HTTPS or SSH protocols. The use of the Software will be carried out on these computers. The data will be loaded to the web server from the Customer’s local computer. As soon as the Customer starts the calculation, Seamplex may forward the data and the settings to external computer centers; as soon as results are created on these computers, they are sent to the web server and can be called up by the Customer in his Account. Seamplex rents computing capacity in order to enable the use of its software. Seamplex grants use of the software immediately after opening of an Account or activation of specific options, regardless of any assertion of a right of withdrawal. Seamplex hereby provides notice of the possibility of charging a fee for services provided up to that point.

Seamplex takes customary precautionary measures in order to guarantee the security and confidentiality of your data. In particular, the CAD models uploaded by the Customer are both encrypted end-to-end during transmission and at-rest when stored in our servers. See our privacy policy for details. You understand that you are completely responsible and liable of any copyright, patent, trademark or any other kind of intellectual property infringement associated to or derived by the inappropriate usage of such customer-provided data.

You can initially use the software free of charge. However, you can select options in his account that are subject to a fee. Users who use the Software free of charge can only run projects using sample CAD models provided by Seamplex. Users with non-free subscriptions may upload their own CAD models.

In order to be able to use the software, you shall personally upload or specify the data necessary to run a computation and review its completeness and correctness. These data include, inter alia, geometric information (CAD), selection of analysis type, material parameters, boundary and/or initial conditions, numeric settings, etc. This listing can only be exemplary. You warrant that you have authorization to use and, as the case may be, to publish the data, representations and images.

You are solely responsible for the correctness and completeness of the data you transmit and the modeling of the technical system. The Software can only perform a calculation correctly using completely transmitted and correct data. Seamplex therefore assumes no liability for the correctness of the calculated results with regard to the physical process and/or systems being modeled. In case you generates a PDF report with the results of a CAEplex project, you are fully responsible for the technical, industrial and/or commercial usage and liability associated with such report. Seamplex does not sign nor endorse nor take any responsibility for the direct or indirect damages associated with either the results of a CAEplex project or the contents of a CAEplex-generated report.

You can access the data that you loaded into your Account at any time, and can access the results obtained by the use of the CAEplex at any time. If CAEplex would be temporarily unable to provide these data and results for technical reasons, then Seamplex agrees to remedy the malfunction promptly. This excludes events of force majeure.

You are not entitled to transfer the right of use to third Parties. However, members of your organization or authorized third Parties are permitted to upload data. You are not authorized to use the CAEplex through your Account for third Parties. In case of unauthorized usage, Seamplex is entitled to block the Account. In this case, the Customer is obligated to maintain the email address until completion of this process.

4.1 Limitation of liability

If the Software made available has an error, then you shall have a right to remedy of defects. You shall have a right to withdraw if Seamplex can not remedy an error in the computation within a reasonable period. These two sentences shall apply subject to the limitation of liability and warranty within this regulation.

As long as you use the Software free of charge, Seamplex shall only be liable for wrongful intent and gross negligence. When a fee is paid for use, Seamplex warrants the functionality of the Software provided for use, with the proviso that the customary defects that technically cannot be excluded (e.g. bugs) in the Software will be removed in each case immediately upon their discovery. If a computed result is false due to a defect that has then been remedied, the specific computation process can be repeated without being charged a usage fee.

Otherwise, liability for damage and consequential damage due to defects is limited to wrongful intent and gross negligence. Any and all liability is excluded for the modeling of the technical system. You understand that the software Seamplex provides solves a set of algebraic equations that, up to a certain level, approximate a set of partial differential equations that, up to another certain level, represent a physical situation. And you claim to also understand up to which extents these approximations and representations constitute a valid model of such physical situation. Seamplex’ liability for its agents is limited to wrongful intent and gross negligence. Liability for data loss is limited to wrongful intent and gross negligence.

The inadequacies that customarily occur in the software provided by Seamplex cannot be excluded shall be kept to the lowest level possible by Seamplex regularly revising the Software. Such revision shall be carried out outside of the main usage periods insofar as technically possible. If you are a commercial customer, then you are obligated to notify us promptly of defects in the Software that you becomes aware of. Similarly, you shall provide notice of any defects becoming known to you in the interaction of the various components of the Software.

Seamplex also uses third-party software (both standalone programs and libraries) for individual parts of computation runs. We select this software to the best of our knowledge and belief. Seamplex assumes a warranty for the functionality of the third-party software provided for use only in case of wrongful intent and gross negligence, but agrees to report errors to the author of the software immediately after their discovery. If a computed result is false due to a defect that has subsequently been remedied, the specific calculation process can be repeated without a usage fee being charged.

You may request that Seamplex employees help in the creation of a computation run. In this case as well, we exclude any and all liability for the correctness of the modeling of the technical system. We can help exclusively in setting the tool, but shall in no case make our own assessment of what is technically necessary for the Customer.

Should individual provisions be or become invalid or contestable at all or in part, this shall not affect the applicability and validity of the other clauses set forth herein, and this provision shall be interpreted and/or supplemented in such a way that the intended meaning and purpose is achieved to the extent possible.

Subject to your compliance with these Terms and Conditions, and any additional terms that may apply to particular services offered by us, we grant you a non-exclusive, non-transferable, limited, personal license to access and use the Service in accordance with these Terms and Conditions. The license granted herein is expressly made subject to the following limitations and restrictions:

5 Passwords & Account Access

The user who created the CAEplex account and whose payment method is charged has access and control over the User Account to maintain control over the account and to prevent anyone from accessing the account. You are responsible for updating and maintaining the accuracy of the information you provide to us relating to your account. We can terminate your account or place your account on hold in order to protect you, Seamplex or our partners from identity theft or other fraudulent activity.

The password of your User Account is not directly stored in our servers. We first compute a salted hash using the Blowfish algorithm, and it it this salted-hash string what we store. At login-time, we encrypt the password provided in the login form and allow access only if the two encrypted strings match. The passwords entered into the website’s forms are transferred end-to-end encrypted to our servers under the TLS protocol over HTTPS. See our security measures for further details.

6 Handling of financial data

Information regarding the Payment Method (i.e. credit card holder name, number, CVC, expiration date, etc.) is transferred to our servers encrypted end-to-end using TLS over HTTPS but it is not stored in our servers at all. We immediately send that information to a PCI-compliant third-party provider, also end-to-end encrypted using TLS of HTTPS, that is in charge of processing the charges to said Payment Method. We only store a hashed token that we use to charge the service fee in the monthly-basis format described above in “Billing.” This token cannot be directly related to the Payment Method information, which is safely stored in a PCI-compliant server.
