Locations settings
Set geographic restrictions to control where responses come from.
This section covers how to use the Screening tab to:
- Restrict respondent locations
- Block specified IP addresses
- Select allowed operating systems
- Select allowed web browsers
Restrict respondent locations 
To ensure your data comes from specific regions, you can restrict respondents based on their location. Simply choose the countries or regions you want to allow or exclude, and only users from those locations will be able to proceed. This helps you focus on the right audience.
Block specified IP addresses
Easily block specific IP addresses to prevent unwanted respondents from accessing your survey. This is useful for blocking known fraudulent sources or internal testers to ensure accurate results.
Blocking IP addresses
Add IP addresses to prevent unwanted access.
Select allowed operating systems
Control who can access your studies by selecting the operating systems you want to allow, such as Windows, macOS, Linux, ChromeOS, Android, or iOS. If a respondent is using an unsupported OS, they won’t be able to proceed. This helps maintain consistency and compatibility with your study requirements.
Selecting operating systems
Specify which operating systems are allowed for participation.
Select allowed web browsers
Ensure a smooth experience by allowing only selected web browsers like Chrome, Firefox, Safari, Edge, Opera, or Samsung Internet. Respondents using unsupported browsers won’t be able to participate. This prevents compatibility issues and enhances data integrity.
Selecting web browsers
Limit survey access to specific web browsers for optimal performance.
