Last updated: September 27th, 2025

At UsernameChecker, we value the privacy of our users. This privacy policy explains how we collect, use, and protect your personal data when you visit our website, use our services, or create an account. By using our website or services, you agree to the terms of this privacy policy.

1. Information We Collect

We collect the following information to provide our services and improve user experience:

• Email Address: We collect your email address to create an account, identify you as a user, and send updates regarding new features, special deals, and token package offers.
• Username: We store your username as part of your account, which allows us to identify you on our platform.
• Password: We store your password securely using SHA256 encryption. We do not store plain passwords, and the password is only used for authentication purposes.
• Profile Picture (PFP): If you upload a profile picture, we store the link to that image.
• Search History: We store the usernames you check, including the platforms they were checked on, whether they were available, the search status, timestamp, and duration. This allows you to view your past search history on your profile page. We do not share your search history with other users or third parties.
• IP Address: We collect your IP address to help prevent users from creating multiple accounts. Your IP address is not used for any other purpose.
• Country: We collect the country where you are located during account creation.
• Account Activity: We track when your account was created and your last login time for user management purposes.

2. How We Use Your Information

We use the information we collect for the following purposes:

• To provide, maintain, and improve our services.
• To send you important updates about our services, including changes to features, policies, and promotional offers (if you have opted in to receive such communications).
• To display your username check history on your profile page.
• To prevent the creation of multiple accounts by tracking IP addresses.

3. Data Sharing and Third Parties

We do not sell or rent your personal information to anyone. However, we use third-party services, including Google AdSense, to display ads on our website. These services may use cookies, device identifiers, or similar technologies to deliver relevant ads and measure their performance. For example, Google’s use of advertising cookies enables it and its partners to serve ads to you based on your visits to this and other websites. You may opt out of personalized advertising by visiting Google Ads Settings. You can also learn more at About Google Ads.

4. Cookies and LocalStorage

For account management and login, we do not use cookies. Instead, we use localStorage to store the JWT token for authentication purposes. This allows you to remain logged in across sessions. No sensitive information is stored in localStorage. However, third-party services (such as Google AdSense) may use cookies or similar technologies to serve ads and measure their performance. These cookies may track non-personally identifiable information about your browsing activity.

5a. Advertising and Third-Party Vendors

We display advertising through Google AdSense and its partners. Third-party vendors, including Google, use cookies to serve ads based on a user’s prior visits to our website or other websites. Google and its partners may also use advertising identifiers to personalize ads. Users may opt out of personalized advertising by visiting Google Ads Settings. If you are located in the European Economic Area (EEA), the United Kingdom, or Switzerland, we comply with Google’s EU User Consent Policy and will present you with a consent banner that allows you to manage your cookie preferences.

5b. Data Hosting Location

Your personal data, including the information we collect, is hosted on servers located in the United States. This means that your data may be transferred to and stored in the U.S. While we take reasonable steps to protect your data, please be aware that data protection laws in the United States may differ from those in your country of residence, including countries within the European Union (EU). We take appropriate measures to protect your data in accordance with applicable laws and industry standards.

6. How We Protect Your Information

We take appropriate measures to protect your personal information, including encryption of passwords using SHA256. While we implement security best practices, no method of online data transmission or storage is 100% secure. We cannot guarantee absolute security, but we strive to protect your information to the best of our ability.

7. Your Rights and Data Deletion

You have the right to request access to the personal data we hold about you, as well as the right to request deletion of your account and associated data. If you would like to delete your account or request information about the data we store, please contact us at [email protected] with your email address and username.
