Privacy Policy
1. Information We Collect
When you create an account or save a group, we collect your name, email address, profile details shared by your provider, saved group metadata, and preference settings. If you are signed in, we also store your recent tool run history — including the names and options you enter and the results you generate — so you can restore past runs across devices. We also capture basic device data such as IP address, browser type, and timestamps to prevent fraud and maintain system reliability.
2. How We Use Your Information
We process personal data to authenticate you, sync saved histories across devices, provide support, improve the generator, and send essential service updates. We do not sell personal information and only share it with trusted processors that help us deliver the product.
3. Legal Basis and Retention
We rely on contractual necessity and our legitimate interest in operating Random Group Generator, and when required we seek your consent. Personal data is retained only while your account remains active or as needed to meet legal or compliance obligations.
4. Cookies and Similar Technologies
We use essential cookies to keep you signed in (if you use an account), remember language and theme preferences, and protect sessions. We may use analytics cookies to understand aggregate traffic. Advertising partners may set their own cookies as described in the Advertising section. You can control cookies through your browser settings; blocking some cookies may limit site features.
5. Advertising and Third-Party Cookies
We display advertising through third-party advertising networks — currently Monetag, and previously Adsterra; Google AdSense may also serve ads where available. These networks and their partners may use cookies, similar technologies, and advertising identifiers to measure advertising performance, prevent fraud, and show personalized or non-personalized advertising where permitted. We do not intentionally include names, email addresses, phone numbers, uploaded rosters, or other directly identifying information in advertising requests. You can manage advertising preferences through Google's Ad Settings at https://www.google.com/settings/ads and, where available, the choices provided by https://www.aboutads.info/choices/. Where applicable law requires consent, we will follow the relevant consent requirements before enabling the relevant advertising feature. For more information about how Google uses data on partner sites or apps, see https://policies.google.com/technologies/partner-sites. In the European Economic Area and the United Kingdom, these advertising scripts only load after you give consent through the consent banner on this site, and you can change or withdraw that choice at any time through the cookie settings link in our footer.
6. Consent for EEA and UK Users
If you visit from the European Economic Area or the United Kingdom, we ask for your consent before storing or accessing information on your device (such as cookies) and before processing personal data such as IP addresses and device identifiers for personalized advertising. A consent banner is shown before any advertising script loads, and no advertising cookies or identifiers are set before you choose. You can change or withdraw your consent at any time through the cookie settings link in our footer or via your browser settings, and refusing consent never blocks access to our tools.
7. Interest-Based Advertising
Google and its partners use advertising cookies, including the DoubleClick cookie, to serve ads based on your prior visits to this and other websites. This helps keep Random Group Generator free. You may opt out of personalized advertising through Google's Ads Settings (https://www.google.com/settings/ads), via www.aboutads.info, or, if you are in the EEA or UK, through www.youronlinechoices.eu. Opting out does not mean you will stop seeing ads; it means the ads you see will be less relevant.
8. Children's Privacy
Random Group Generator is intended for teachers, trainers, facilitators, event organizers, and other adult users, and it is not directed at children under the age of 13. We do not knowingly collect personal information from children under 13. When an adult uses the generator for a class or activity, participant names are processed only to produce the requested groups, and saved generation history can be deleted at any time. If you believe a child has provided us with personal information, contact us at zhangruyide@gmail.com and we will promptly delete it.
9. Security and Third Parties
All traffic is encrypted via HTTPS, access to personal data is restricted to authorized staff, and we regularly review our security posture. We only engage third-party infrastructure and authentication partners that commit to comparable safeguards.
10. Your Privacy Choices
You may access, update, export, or delete your account data at any time. Random Group Generator is the controller of personal data collected through this site. Depending on where you live—for example, in the EEA or UK under the GDPR, or in California under the CCPA—you may have the right to access, correct, delete, or port your personal data, and to object to or restrict certain processing. To exercise these rights or withdraw consent, contact us and we will respond within a reasonable timeframe.
