Namechk is a search tool that searches social media platforms and domains for usernames or website names. Entering a query returns results from more than a hundred domains and social media platforms, indicating whether or not the username has been registered on that platform / with that domain. Domains or usernames that return as red indicate that they are registered with the associated platform, while names that return green indicate the username is still available on that platform.
Namechk's functions can be a helpful OSINT tool for tracking individuals (particularly those with unique usernames) across platforms, as well as for understanding the spread of an entity's domain registrations.
The tool also provides username generators and reviews and details about domain and web hosting.
None.
One username may be used across several platforms by different people; results from Namechk should be treated as clues rather than as a definitive results.
Common usernames may flag on many/all platforms and fail to provide any useful clues.
Results are not always 100% accurate— be sure to double-check for false positives.
It also states that it "implements a variety of security measures to maintain the safety of your personal information," but fails to elaborate on how.
Caution should be taken if providing any personal information.

Namechk's states that it "collects information from you when you register on Namechk or fill out a form," indicating that it may be collecting information when the search field is utilised. It further notes that it uses cookies, and collects any provided personal information (such as that collected during registrations or purchases) to personalise user experiences, improve the website, improve customer service, and process transactions. Additionally, information is sometimes shared with "trusted third parties."

Namechk's guide details how to use the domain searching function. (Note that this is primarily geared toward users ostensibly looking to register a new business or entity's domain name.)
A 2018 Medium by Jake Creps details how to use Namechk in the course of OSINT investigations. (Note that some details may be out of date as the tool's interface has changed slightly since the article was written.)
