What types of information does Graphtor collect and how is it used?
In order to give you the best experience on our Website, Graphtor may collect information about you. Typically, we may ask you to submit personal and/or demographic information if you decide to:

  1. sign up for a Graphtor account (i.e., purchase a membership plan);
  2. use our Graphtor Referrals feature;
  3. sign up to receive Graphtor newsletters; or
  4. send us a message using our "Contact Us" form.

The types of information requested for each feature above and the way the information is used are detailed by category below. Under all circumstances, we will only collect the information deemed reasonably necessary to fulfill your online requests and our legitimate business objectives.

Graphtor Account Registration
To create a Graphtor account, we ask you for certain personally identifying information, including your full name, e-mail address, postal address, telephone number, and billing information (such as a credit card number). We may also ask you to create a password and to provide other non-personal information such as your gender, grade level, hobbies and interests, and other information (also known as "demographic information").  We may link this demographic information to your personal information.

Once collected, we use the information above to: (i) create and give you access to your Graphtor account; (ii) process and ship your orders; (iii) communicate with you (via e-mail or phone) about the status of your orders; (iv) answer any requests that you may have; and (v) send you Graphtor newsletters and provide you with promotional information unless you direct us not to send these items.
From time to time, we are approached by third party companies and organizations that provide calculator-related special offers or other offers that we believe may be of interest to you. To extend these offers to you, we may use your Graphtor account information to send out promotional mailings on their behalf. If you decide to sign up for a third party offer, then with your consent we may also share your Graphtor account information with the third party offer provider. We see this as a value-added service helping you find useful products or services. We strive to limit the notices and communications to those that we think you would appreciate receiving. If you want to be excluded from these promotional mailings, you may opt out by logging in to My Account and updating your E-mail Subscriptions.

We may use your Graphtor account e-mail address to send you service-related announcements that tell you about updates to our Privacy Policy or Terms of Service, new areas or features on our Website, changes to our online service or technical support policies, and other related changes.
We may also use your personal and demographic information in aggregate for our internal marketing and demographic studies, so we can constantly improve the online products and services we provide you and to better meet your needs.

Graphtor Referrals
When you use the Graphtor Referrals Program (or the "Referral Program"), we may ask you to provide information such as your friends' first names and e-mail addresses and your first name and e-mail address. In return, you may receive discounts on fees, coupons, or payments to you. During and after participation in the Referral Program you and/or your friends may receive additional communications from us or our vendors in relation to the Referral Program and you and/or your friends' participation in it. The data collected through the Referral Program is only used for the operation and ongoing maintenance of the Referral Program and will not be distributed to any third parties other than those Graphtor vendors that may be helping us in the operation and maintenance of the Referral Program and as set forth in this Privacy Policy. You and your friends may opt-out of participation in the Referral Program at any time via opt-out links in all communications made to you and your friends through the Referral Program, or by sending an e-mail to

What happens if I refuse to provide my personal information to Graphtor?
If you choose not to submit personal information when requested, you will not be able to receive our Services, or rent calculators from Graphtor and it will limit the services we can provide you. For example, if you refuse to share your email address, you will not be able to create a Graphtor account or receive our newsletter. To simply browse our Websites, however, you do not need to give us any personal information.

Does Graphtor use cookies, or other passive means to collect information?
Like many Web sites, sets “cookies” on your computer. Cookies are alphanumeric identifiers that we transfer to your computer’s hard drive through your Web browser, allowing us to automatically identify you when you return to our Website. They help us to match the calculators you’ve chosen to rent or buy with your individual account, and to personalize the Website for you. Information contained in a cookie may be linked to your personally identifying information. If cookies are not enabled on your Web browser, you will not be able to use or may not receive the full benefits of the Graphtor Website or the Graphtor Service. The "help" menu on most Web browsers will tell you how to enable cookies.

Your order and billing history are also tracked automatically from the beginning of your Graphtor membership. This allows you to log in to My Account and see a complete list of calculators you’ve rented or bought from us.
In the course of serving advertisements to this site, our third-party advertiser may place or recognize a unique cookie on your browser.

Who is collecting my personal information and is it shared with anyone?
The information that you disclose on the Graphtor Websites is collected by Graphtor or by a vendor on Graphtor's behalf; and, is used in accordance with the practices set forth above. A breakdown of our data disclosure policies follows.

Agents and Contractors
We use outside companies, agents, and contractors (“vendors”) to perform some important Graphtor tasks, such as processing credit card transactions, delivering your orders, and operating and maintaining our Referral Program. In the course of doing so, these vendors can come into contact with some of your personally identifying information. However, we only give them access to the information they need in order to actually perform their tasks. Additionally for those vendors with whom we have a contractual relationship, they have agreed to be bound by the terms of this Privacy Policy-that is, they must treat your personal information the same way we do.

Co-Sponsors and Promotional Partners
From time to time, we may run contests, special offers, or other events or activities ("Events") on our Website that will be subject to the terms and conditions stated for that Event. Information collected for these Events may include personal information (e.g., name, mailing address, etc.) and may be collected by or shared with a third party sponsor, co-sponsor, or other reputable third party (e.g., promotional partner, retailer, or calculator or magazine publisher). If you provide information to such third parties, you give them permission to use it for the purpose of that event and any other use that you approve. We cannot control third parties' use of your information. If you do not want your information to be collected by or shared with a third party, you can choose not to participate in these Events at the time of the Event or when the information is collected.
In some instances, we may have an arrangement with a promotional partner or retailer, whereby they share with us customer information collected on their website. In the event that we receive such data and combine it with our customer records, the combined information will be treated in accordance with this Privacy Policy. Otherwise, all such information is subject to the privacy policy under which it was collected.

Disclosure and/or Transfer of Personal Information
We may disclose any and/or all personal information about you in the good faith belief that we are required to do so by law, including but not limited to requests pursuant to subpoena or court order, and/or disclosure to local, state, or federal law enforcement, or other government officials pursuant to investigations they are conducting. In addition, in the event of a merger, acquisition, reorganization, bankruptcy, or other similar event, we may sell, transfer and assign your information to our successors and assigns.

Aggregate Information
We may provide our prospective partners, advertisers, and other third parties with aggregate data about members and visitors to the Graphtor Website. However, such data is anonymous, and we do not disclose personally identifying information about specific users.

Can I choose how my personal information is used?
If you wish to opt out of receiving the Graphtor newsletter, special offers, and promotional information, log in to My Account and change your E-mail Subscriptions. In addition, at the bottom of every Graphtor newsletter sent to you, we provide you the opportunity to discontinue receiving future communications (i.e., unsubscribe).

How can I view or update my personal information?
To view or update your name, e-mail address, password, billing address, credit card number, e-mail subscription preferences, or other account information, log in to My Account.
