Terms of Service

Nanday.Com Equation Balancer

Nanday.Com provides its Equation Balancer Service to you, subject to the following Terms of Service, which may occasionally be updated by us without prior notice to you.

Under normal circumstances, the only email communication you will ever receive from us will be a confirmation when you purchase a subscription. However, you understand and agree that we may send you service announcements or administrative messages pertaining to your account. We will never put you on a mailing list, and we will never distribute your email address to anyone. We currently do not use cookies, and the only personal information we gather from you is your email address.

The Equation Balancer will instantly balance almost any unbalanced chemical equation. Equations may be entered in a very free-form manner. Guest users are very limited in the number of reactants and products which are allowed in each equation, and advertising banners are displayed on all guest-access pages. Premium accounts, available for a very reasonable cost, allow users to balance equations with a virtually unlimited number of reactants and products. Furthermore, premium account holders will not be shown any advertising banners on their equation balancing pages.

You understand and agree that the Equation Balancer Service is provided "as-is" and that we assume no responsibility for the accuracy of the Service or for the occasional unavailability of the Service. We have an excellent "uptime" record but we provide no guarantees in that respect. As with any computer system, reasonable "downtimes" are to be expected.

You will select a password when you register. You are responsible for selecting a password which will not be easily guessed by others, and for maintaining the confidentiality of the password and account. You agree to ensure that you logout from your account at the end of each session. We cannot and will not be liable for any loss arising from your failure to comply with this stipulation. In particular, if you fail to logout while using a public terminal, someone else may gain access to your account. If this happens, your account may be terminated without notice, and you will not be entitled to a refund for any time remaining in your subscription. You further agree to immediately notify us (using the "contact" link found on most Nanday.Com pages) of any unauthorized use of your password or account or any other breach of security. You must always provide us with your correct email address, because if you ever forget your password, we can only send your password to the current email address we have on file for you.

You agree not to modify our software in any manner or form, or to use modified versions of it, including (without limitation) for the purpose of obtaining unauthorized access to the Service. You agree not to access the Service by any means other than through the interface that is provided by us for use in accessing the Service.

You understand and agree that all premium access purchases which you make are final. No refunds will be available unless we terminate our Service. If our site is down for a significant amount of time during your premium access period, we may compensate you by extending your subscription for an appropriate amount of time. To request such compensation, click on a "contact" link which is found on most Nanday.Com pages and provide as many details as possible. State that you are requesting compensation for downtime, and include your user name, email address, and the times, including your time zone, during which you attempted to use our Service but it was unavailable.

If you pay with an e-check, your access will be upgraded only when your e-check clears, which is usually four business days. If you submit an e-check payment and then decide that you do not want to wait for access, you may make another purchase using an instant payment method and get instant access. Then use a "Contact" link at the bottom of most Nanday.Com pages to explain the situation, and we will issue a prompt refund of the e-check payment. If you do not contact us before your original payment clears, that payment will be applied to extend or reactivate your account.

We grant you a personal, non-transferable license to use the Equation Balancer premium access on a single computer. You agree that any subscription to the Service which you purchase is for your own personal use only. You agree not to share, give, rent, or sell your username/password or in any other way provide access to the Service to any other person. If you are found to be in violation of this provision, your account may be terminated without notice, and you will not be entitled to a refund for any time remaining in your subscription.

If you use a browser "anonymizer", you may be unable to use your premium account. In our tests, the site does work fine using an anonymizer, but we do not guarantee that it will work with all anonymizers. As stated in our Privacy Policy, we do not collect any personal information from you, so you may visit our site in confidence without using an anonymizer. If you purchase a premium account and insist on using an anonymizer, we are not responsible if you are unable to use the premium features, and we will not issue a refund.

You must enter complete, correct, unbalanced equations, using the proper chemical symbols (not names). If you specify acidic or basic solutions, H2O and H+ or OH- will be added automatically as needed, but this site will not attempt to determine any other missing items. In particular, you may not supply just the reactants -- this site will not figure out the products of the reaction.

Please note that this site generally cannot balance equations containing compounds depicted with a Chemical Period. In chemical notation, this is used to separate two components of a compound; for example, to separate the water of hydration from the rest of a compound. This is denoted in any of several ways, including those in the following examples: CaCl2 · 6H2O or CaCl2 * 6H2O. There is no way for you to enter such a compound in that form on this site.

This site is also unable to balance equations which have multiple correct ways of being balanced. For example, the unbalanced equation I4O9 = I2O6 + I2 + O2 can be balanced in four different ways, but it can not be balanced on this site.

Sometimes the Equation Balancer is unable to balance equations which are the sum of other equations, or when the reactants are the same as (or occasionally if they are too similar to) the products, or if extraneous reactants or products have been entered.

You agree that we assume no responsibility for the inability of the site to balance these or any other kind of equation. No refunds will be offered in compensation for this inability.

You agree that you will only use the Equation Balancer in one window on one computer at any time. Anyone logging into your account on one computer while you are still logged in on another computer, will cause the first instance to be automatically logged out. This will also be noted in your account as suspicious activity. If we determine in this way or in any other way that you have distributed your username and password to anyone else, your account will be terminated without notice, and you will not be entitled to a refund for any time remaining in your subscription.

We reserve the right at any time to modify or discontinue the Equation Balancer Service with or without notice. Prices for premium access are subject to change. You agree that if prices go down, you are not entitled to a refund for any premium access which you may have purchased at a higher price, and if prices go up, you are not entitled to purchase more time at your original cost. You agree that we shall not be liable to you or to any third party for any modification, suspension or discontinuance of the Service. Our only obligation to you in the event of discontinuance of the Service would be a prorated refund of any remaining part of a subscription which you may have purchased.

You agree that we, in our sole discretion, may terminate your account without compensation if we believe that you have violated or acted inconsistently with the letter or spirit of the Terms Of Service. You agree that any termination of your access to the Service under any provision of these Terms Of Service may be effected without prior notice, and acknowledge and agree that we may immediately deactivate or delete your account. Further, you agree that we shall not be liable to you or any third-party for any termination of your access to the Service.

You agree to indemnify and hold Nanday.Com, and its affiliates, officers, agents, or other partners, and employees, harmless from any claim or demand, including reasonable attorneys' fees, made by any party due to or arising out of your use of the Service, your inability to use the Service, or your violation of these Terms Of Service.

You expressly understand and agree that:
1. Your use of the Service is at your sole risk. The Service is provided on an "as is" and "as available" basis. We expressly disclaim all warranties of any kind, whether express or implied.
2. We make no warranty that (a) the Service will meet your requirements, (b) the Service will be uninterrupted, timely, secure, or error-free, (c) the results that may be obtained from the use of the Service will be accurate or reliable, (d) the quality of any services or information purchased or obtained by you through the Service will meet your expectations, and (e) any errors in the software will be corrected.
4. No information obtained by you from our site shall create any warranty not expressly stated in the Terms Of Service.

You expressly understand and agree that we shall not be liable for any direct, indirect, incidental, special, consequential or exemplary damages resulting from:
(1) the use or the inability to use the Service;
(2) the cost of procurement of substitute services resulting from any data, information or services purchased or obtained or messages received or transactions entered into through or from the Service;
(3) any other matter relating to the Service.

This document constitutes the entire agreement between you and Nanday.Com and governs your use of the Service, superceding any prior agreements between you and us. The Terms Of Service and the relationship between you and us shall be governed by the laws of the State of California without regard to its conflict of law provisions. You and Nanday.Com agree to submit to the personal and exclusive jurisdiction of the courts located within the county of Los Angeles, California. The failure of us to exercise or enforce any right or provision of the Terms Of Service shall not constitute a waiver of such right or provision. If any provision of the Terms Of Service is found by a court of competent jurisdiction to be invalid, the parties nevertheless agree that the court should endeavor to give effect to the parties' intentions as reflected in the provision, and the other provisions of the Terms Of Service remain in full force and effect. You agree that regardless of any statute or law to the contrary, any claim or cause of action arising out of or related to use of the Service or the Terms Of Service must be filed within one (1) year after such claim or cause of action arose or be forever barred.
