UsernameChecker Privacy Policy
Last updated: 13 August 2026
UsernameChecker (“we”, “us”) operates https://usernamechecker.net. This policy describes what we collect, how Google advertising cookies work on this site, and how to contact us.
Who we are
Operator contact: contact@usernamechecker.net. Mail sent to that address is handled by the site operator.
Information you provide
- Usernames you type into the checker
- Email address if you request a CSV export of results
- Messages you send to our contact address
Do not submit passwords, private keys, or other people’s personal data. This tool is for brand-handle checks only.
Information collected automatically
- IP address, browser type, and approximate request time (server logs and security filters)
- Pages requested, including search URLs such as /yourhandle
- Referring URL when the browser sends one
We use this data to run the site, stop scanners, and understand which public pages are useful. Recent searches may be listed on the site and included in the sitemap.
Cookies and Google AdSense
We use Google AdSense to show ads. Google and its partners may use cookies (including the DoubleClick / IDE cookie) and similar technologies to serve ads based on your visits to this site and other sites, measure ad performance, and limit how often you see an ad.
- Publisher ID:
ca-pub-3773722029096985(also listed in ads.txt) - Google’s explanation: How Google uses information from sites that use our services
- Opt out of personalized Google ads: Google Ads Settings
- Industry opt-out: aboutads.info/choices (US) and youronlinechoices.eu (EU)
If you block cookies, ads may still appear but may be less relevant. Essential cookies or local storage may still be used for security (for example blocking abusive IPs).
How we use information
- To run username availability checks and show results
- To email a CSV when you request one
- To keep a public recent-search list and sitemap of example handles
- To detect abuse and block vulnerability scanners
- To display ads and measure that they loaded
- To respond to email you send us
We do not sell lists of searched usernames. We do not use the checker to build marketing profiles of private individuals.
Legal bases (EEA/UK visitors)
Where GDPR applies: we process server logs and security blocks as legitimate interests in operating a safe website; we process contact email to respond to your request; advertising cookies that are not strictly necessary should only run with consent where required by local law. Use the opt-out links above if you do not want personalized ads.
Children
This site is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child submitted personal data, email us and we will delete it where feasible.
Retention
Server logs and security bans are kept only as long as needed for operations and abuse prevention. Recent-search records may remain while they are listed on the site. Email you send is kept as long as needed to handle the request.
Your rights
You may request access, correction, or deletion of personal information we hold about you, subject to security and legal limits. Email contact@usernamechecker.net. You can also use browser controls to delete cookies.
International transfers
Google and hosting providers may process data in the United States or other countries. Google’s ads technologies are described in their policies linked above.
Changes
We will post updates on this page and change the “Last updated” date.
