Terms Of Service

By using our services, you agree to these terms. Please read them carefully.

​

Using our Services

You must follow any policies made available to you within the Services. Don’t misuse our Services. For example, don’t interfere with our Services or try to access them using a method other than the interface and the instructions that we provide. You may use our Services only as permitted by law, including applicable export and re-export control laws and regulations. We may suspend or stop providing our Services to you if you do not comply with our terms or policies or if we are investigating suspected misconduct.

Using our Services does not give you ownership of any intellectual property rights in our Services or the content you access. You may not use content from our Services unless you obtain permission from its owner or are otherwise permitted by law. These terms do not grant you the right to use any branding or logos used in our Services. Don’t remove, obscure, or alter any legal notices displayed in or along with our Services.

Our Services display some content that is not ours. This content is the sole responsibility of the entity that makes it available. We may review content to determine whether it is illegal or violates our policies, and we may remove or refuse to display content that we reasonably believe violates our policies or the law. But that does not necessarily mean that we review content, so please don’t assume that we do.

In connection with your use of the Services, we may send you service announcements, administrative messages, and other information. You may opt out of some of those communications.

Some of our Services are available on mobile devices. Do not use such Services in a way that distracts you and prevents you from obeying traffic or safety laws.

Guidelines for Using AI-Generated Content in Educational Settings:

• Initial Draft Use: View AI-produced materials as preliminary drafts that need your expertise to reach completion. Typically, these should be seen as 90% finished, requiring your input to perfect the final 10%.

• Critical Review for Integrity and Bias: AI technologies can sometimes introduce errors, biases, or unverified information. It is imperative to scrutinize the content for these issues before it is utilized in an educational context.

• Update and Context Awareness: Keep in mind that our AI’s knowledge base is current only through the end of 2023. For topics beyond this date, additional verification from up-to-date sources is necessary.

• Personal Information Caution: Do not input or process personal identifiable information of any individuals within our service. Violations of privacy laws or institutional policies can lead to severe consequences, including the termination of your access to our services.

Liability Shield Agreement:

As a user of our services, you agree to absolve and safeguard Radius, its executives, staff, representatives, and third parties from any legal claims, damages, responsibilities, and costs (including legal fees) incurred due to non-compliance with our Terms of Service, unauthorized usage of our services, or infringement of any proprietary, privacy, or personal rights. Radius retains the right to manage the legal defense against such claims at its own expense and requires your full cooperation in defending against these claims under the terms provided here.

If you want to take full advantage of the sharing features we offer, we might also ask you to create a publicly visible Google Profile, which may include your name and photo.

• Log information When you use our services or view content provided by Google, we automatically collect and store certain information in server logs. This includes:

• Location information When you use Google services, we may collect and process information about your actual location. We use various technologies to determine location, including IP address, GPS, and other sensors that may, for example, provide Google with information on nearby devices, Wi-Fi access points and cell towers.

• Unique application numbers Certain services include a unique application number. This number and information about your installation (for example, the operating system type and application version number) may be sent to Google when you install or uninstall that service or when that service periodically contacts our servers, such as for automatic updates.

• Local storage We may collect and store information (including personal information) locally on your device using mechanisms such as browser web storage (including HTML 5) and application data caches.

• Cookies and similar technologies We and our partners use various technologies to collect and store information when you visit a Google service, and this may include using cookies or similar technologies to identify your browser or device.

We do not directly collect any personally identifiable information (PII) from students without parental consent.

How we use information we collect

We may use your email address to send you service-related notices (including any notices required by law, in lieu of communication by postal mail). We may also use your email address to send you marketing messages. If you don’t want to receive such messages, you may opt out by following the instructions in the message.
