Wherobots Inc. (“**Wherobots**,” “**we**,” “**us**,” or “**our**”) has prepared this Privacy Policy to explain (1) what personal information we collect, (2) how we use and share that information, and (3) your choices concerning our privacy and information practices.
## **Applicability of this Privacy Policy**
We provide a spatial data analytics and AI platform (the “**Services**”). This Privacy Policy applies to personal information that we collect in connection with the Services, our mobile applications, our website(s), including [https://www.wherobots.com](https://www.wherobots.com) and products and/or services that link to this Privacy Policy.
If you are a customer of Wherobots, this Privacy Policy does not apply to personal information that we process on your behalf (if any) as your service provider. Such personal information shall instead be governed by the terms and conditions of the separate customer agreement or terms of service that you have agreed to with Wherobots. In addition, our Services are designed for businesses and are not intended for personal, family, or household use. Accordingly, we treat all personal information covered by this Privacy Policy as pertaining to individuals acting as business representatives, rather than in their personal capacity.
## **Personal information we collect**
**Information you provide to us:**
* **Business Contact Information:** If you are a representative of one of our actual or prospective customers, suppliers or business partners, we may collect personal information about you (such as your name, contact details and role) when entering into an agreement with your company and during the course of our relationship with your company.
* **Account information,** such as your name, email address, and other similar information when you register an account with us.
* **Transaction Information**, such as your credit card or other payment information and authentication details when you purchase a license for the Services. We do not directly collect or process your payment card information. Depending on how you purchase our Services, your transactions are processed through a third-party payment processor (such as **Stripe**) or through a cloud marketplace (such as **AWS Marketplace**). These third parties provide your payment information directly to us only in limited circumstances (such as your name and the last four digits of your card for verification) or, in the case of marketplaces, handle the entire billing process on our behalf. Your information is governed by the respective privacy policies of these third parties.
* **Feedback or correspondence,** such as information you provide when you contact us with questions, feedback, reviews, or otherwise correspond with us online.
* **Usage information,** such as information about how you use the Services and interact with us.
* **Marketing information,** such as your preferences for receiving communications about our activities, services, and publications, and details about how you engage with our communications.
* **Other information** that we may collect which is not specifically listed here, but which we will use in accordance with this Privacy Policy or as otherwise disclosed at the time of collection.
**Information we obtain from third parties:**
We may maintain pages on social media platforms, such as Facebook, Twitter, Instagram, and other third-party platforms. When you visit or interact with our pages on those platforms, the platform provider's privacy policy will apply to your interactions and their collection, use and processing of your personal information. You or the platforms may provide us with information through the platform, and we will treat such information in accordance with this Privacy Policy. We may obtain your personal information from other third parties, such as marketing partners, publicly-available sources and data providers.
**Automatic data collection.** We and our service providers may automatically log information about you, your computer or mobile device, and your interaction over time with our Services, our communications and other online services, such as:
* **Device data,** such as your computer's or mobile device's operating system type and version, manufacturer and model, browser type, screen resolution, RAM and disk size, CPU usage, device type (e.g., phone, tablet), IP address, unique identifiers (including identifiers used for advertising purposes), language settings, mobile device carrier, radio/network information (e.g., WiFi, LTE, 4G), and general location information such as city, state or geographic area.
* **Online activity data,** such as pages or screens you viewed, how long you spent on a page or screen, browsing history, navigation paths between pages or screens, information about your activity on a page or screen, access times, and duration of access, and whether you have opened our marketing emails or clicked links within them.
* **Email Open/Click Information.** We may use pixels in our email campaigns that allow us to collect your email and IP address as well as the date and time you open an email or click on any links in the email that we may send to you.
**We use the following tools for automatic data collection:**
* **Cookies**, which are text files that websites store on a visitor's device to uniquely identify the visitor's browser or to store information or settings in the browser for the purpose of helping you navigate between pages efficiently, remembering your preferences, enabling functionality, helping us understand user activity and patterns, and facilitating online advertising.
* **Local storage technologies**, like HTML5, that provide cookie-equivalent functionality but can store larger amounts of data, including on your device outside of your browser in connection with specific applications.

# DBSCAN Python Module
Source: https://docs.wherobots.com/reference/geostats-map-matching/clustering/dbscan-python
DBSCAN is a density-based algorithm ideal for spatial data. It groups records that are closely packed together, marking records in low-density regions as noise. This implementation is built on Apache Spark, Apache Sedona, and GraphFrames to support large-scale datasets and heterogeneous GeometryType features.
## dbscan
Annotates a DataFrame with a cluster label for each record using
the DBSCAN (Density-Based Spatial Clustering of Applications with Noise) algorithm.
```python theme={"system"}
dbscan(
dataframe: DataFrame,
epsilon: float,
min_pts: int,
geometry: Optional[str],
include_outliers: bool,
use_sphere: bool,
is_core_column_name: str,
cluster_column_name: str
)
```
