Information automatically collected

In Short: Some information — such as your Internet Protocol (IP) address and/or browser and device characteristics — is collected automatically when you visit our Services.

We automatically collect certain information when you visit, use, or navigate the Services. This information does not reveal your specific identity (like your name or contact information) but may include device and usage information, such as your IP address, browser and device characteristics, operating system, language preferences, referring URLs, device name, country, location, information about how and when you use our Services, and other technical information. This information is primarily needed to maintain the security and operation of our Services, and for our internal analytics and reporting purposes.

Like many businesses, we also collect information through cookies and similar technologies. The information we collect includes:

Google API

Our use of information received from Google APIs will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

How Do We Process Your Information?

In Short: We process your information to provide, improve, and administer our Services, communicate with you, for security and fraud prevention, and to comply with law.

We process your personal information for a variety of reasons, depending on how you interact with our Services, including:

When and With Whom Do We Share Your Information?

In Short: We may share information in specific situations described in this section.

Do We Use Cookies and Tracking Technologies?

In Short: We may use cookies and other tracking technologies to collect and store your information.

We may use cookies and similar tracking technologies (like web beacons and pixels) to gather information when you interact with our Services. Some online tracking technologies help us maintain the security of our Services, prevent crashes, fix bugs, save your preferences, and assist with basic site functions.

Most web browsers are set to accept cookies by default. You can usually choose to set your browser to remove or reject cookies, though this could affect certain features of our Services.

How Long Do We Keep Your Information?

In Short: We keep your information for as long as necessary to fulfill the purposes outlined in this notice unless otherwise required by law.

We will only keep your personal information for as long as it is necessary for the purposes set out in this Privacy Notice, unless a longer retention period is required or permitted by law. When we have no ongoing legitimate business need to process your personal information, we will either delete or anonymize it.

How Do We Keep Your Information Safe?

In Short: We aim to protect your personal information through organizational and technical security measures.

We have implemented appropriate and reasonable technical and organizational security measures designed to protect the security of any personal information we process. However, no electronic transmission over the Internet can be guaranteed to be 100% secure. You should only access the Services within a secure environment.

Do We Collect Information From Minors?

In Short: We do not knowingly collect data from or market to children under 18 years of age.

We do not knowingly collect, solicit data from, or market to children under 18 years of age, nor do we knowingly sell such personal information. By using the Services, you represent that you are at least 18, or that you are the parent or guardian consenting to a minor's use of the Services. If you become aware of any data we may have collected from children under age 18, please contact us at [email protected].

What Are Your Privacy Rights?

In Short: Depending on your location, you have rights that allow you greater access to and control over your personal information.

In some regions (like the EEA, UK, Switzerland, and Canada), you have certain rights under applicable data protection laws. These may include the right to request access and obtain a copy of your personal information, to request rectification or erasure, to restrict processing, and if applicable, to data portability.

If you are located in the EEA or UK and believe we are unlawfully processing your personal information, you have the right to complain to your Member State data protection authority or UK data protection authority.

Questions about your privacy rights? Email [email protected].

Controls for Do-Not-Track Features

Most web browsers include a Do-Not-Track ("DNT") feature or setting you can activate to signal your privacy preference. At this stage, no uniform technology standard for recognizing and implementing DNT signals has been finalized. As such, we do not currently respond to DNT browser signals. California law requires us to disclose this — because there is no industry standard for honoring DNT signals, we do not respond to them at this time.

Do United States Residents Have Specific Privacy Rights?

In Short: If you are a resident of California, Colorado, Connecticut, and other US states, you may have specific privacy rights.
