This Privacy and Security Policy is provided for the benefit of customers and clients of Ethnus Consultancy Services Private Limited. ("Ethnus") as well as other consumers and parties who use Ethnus and/or its website(s), particularly codemithra.com ("Website", "www.codemithra.com", "Codemithra" or "Ethnus Codemithra"), and/or applications ("Apps") (collectively, "Ethnus Services" or "Ethnus Platform").
Since Ethnus serves several different audiences, customers find it helpful to read the Terms of Use that apply specifically to them based upon the purpose for which they use Ethnus. For this reason, we link to three separate agreements below for employer customers, job seeker customers, and staffing customers, respectively.
For your convenience, we define each of these audiences that Ethnus serves as follows:
"Employer Customer" means an entity using Ethnus Services that is seeking to hire an individual as an employee and/or independent contractor to be employed by it directly.
"Job Seeker Customer" means an individual using Ethnus Services who is seeking to be employed as an employee or independent contractor by an employer.
"Staffing Customer" means a staffing company using Ethnus Services that provides staffing services to their own Staffing Clients.
So long as your use of the Ethnus website and services remains within the scope of the particular audience or customer for which you began using Ethnus (e.g. a job seeker does not use Ethnus as an employer, or an employer does not use Ethnus as a job seeker), the complete Terms of Use applicable to your use of the Ethnus website and services is contained within the applicable Terms of Use linked below.
The following Terms of Use apply to any Ethnus Employer Customer seeking to hire employees or independent contractors for its own business. If you seek to find employees or independent contractors for the benefit of your clients (and not yourself), you need to review the Terms of Use specifically for our Ethnus Staffing Customers accessible at www.Codemithra.com/terms/staffing.
Ethnus, Inc. ("Ethnus") provides online services through which employers and staffing companies seeking employees and independent contractors can efficiently and effectively review and interview candidates. Ethnus provides these services and its suite of features and products through its Apps and Website (collectively, "Ethnus Services") subject to these terms of use ("Terms of Use") and the agreements incorporated herein.
Your privacy is very important to us. We designed our accompanying Privacy and Security Policy to provide important disclosures about how your information will be used by Ethnus in providing you Ethnus Services. These Terms of Use expressly incorporate our Privacy and Security Policy.
Please read these Terms of Use and our Privacy and Security Policy carefully before using any of the diverse Ethnus Services. By visiting the Website, installing any of the Apps, and/or using any of the Ethnus Services, you shall have affirmed your agreement to these Terms of Use.
