GoGuardian, operated by the privately held Liminex, Inc. of El Segundo, California, sells K-12 schools web filtering, classroom screen monitoring (GoGuardian Teacher), device administration (Admin), and AI-driven self-harm and violence alerts (Beacon); the company says its tools reach about 27 million students in roughly 11,500 U.S. schools. The people being watched are children on school-issued devices who cannot opt out: EFF's October 2023 investigation found administrators get near-unfettered access to browsing histories, documents, videos, and alerts, teachers get a live feed of student screens, and the company itself can access the data. EFF's 'Red Flag Machine', built from real GoGuardian data, showed the keyword flagging produces far more false positives than accurate hits, flagging students for college application sites, counseling and therapy resources, sexual-health and LGBTQ+ information, gun-violence and Holocaust history, and political figures; EFF and others have documented that flagging LGBTQ+ content has outed students. To the company's credit, GoGuardian told EFF in mid-2023 it had removed LGBTQ+ terms from its keyword list, and its Product Privacy Policy states it does not sell student information, shows no ads, does not share data for cross-context behavioral advertising, and deletes data on a school's instruction, subject to legal and law-enforcement exceptions; it also reports ISO 27001:2022, SOC 2, and iKeepSafe FERPA/COPPA certifications. GoGuardian responded to EFF's findings that schools have a responsibility to keep students safe on school devices and that it filters harmful content as federal law requires. No regulatory enforcement action or data breach involving GoGuardian was found at primary sources; ownership is traceable only through the company's own disclosures, including a $200 million 2021 investment from Tiger Global.

COLLECTION
The Apple App Store privacy label for 'The GoGuardian App' (seller Liminex, Inc.) discloses data collected and linked to the user's identity including Contact Info (email address, name), User Content (emails or text messages), Search History, Browsing History, Identifiers (user ID, device ID), Usage Data, and Diagnostics, for app functionality, analytics, and diagnostics; no data is declared as used to track users across other companies' apps.
EFF's October 30, 2023 investigation 'How GoGuardian Invades Student Privacy' reports that school administrators using GoGuardian's Admin tool have nearly unfettered access to students' browsing histories, documents, videos, app and extension data, and content-filtering alerts; that GoGuardian Teacher gives teachers a real-time feed of students' screens with no way for students to opt out or confirm they know they are being monitored; and that the monitoring gives schools access to an enormous amount of sensitive student data which the company can also access.
GoGuardian's Product Privacy Policy (last updated May 8, 2026) states that Personal Student Information it may collect includes a student's school-managed Google or Microsoft account information (name, email address, profile ID and image, organizational unit, device identifiers), and, depending on the product, browsing history, IP address, online content, email content, screenshots, video-conference recordings including audio and video of participating students, and keystroke percentage variance (not the actual inputs); using GoGuardian Admin a school can collect the geographic location of devices for device recovery, and the policy states no precise geographic login locations of mobile phones can be accessed or stored.
GoGuardian's website privacy policy identifies the operating company as Liminex, Inc., doing business as GoGuardian, an educational technology company providing K-12 schools and districts and colleges with digital learning tools, and refers users of its products to a separate Product Privacy Policy and, for EEA schools, a Data Processing Addendum.
Wikidata (CC0) records GoGuardian (Q21463101) as an American educational technology company headquartered in El Segundo, California, United States, with official website goguardian.com; the item carries no parent-organization or owned-by statements, consistent with a privately held company.
GoGuardian's leadership page names Rich Preece as Chief Executive Officer and Tyler Shaddix as co-founder and Chief Innovation Officer, who led product strategy from 2015 to 2021 including GoGuardian Teacher and AI-powered Smart Alerts.
GoGuardian's own August 5, 2021 press release announces a $200 million strategic investment from Tiger Global Management, quotes Tiger Global partner John Curtius, and states the platform then served over 22 million K-12 students in the U.S.; the company is privately held, so this self-disclosure and Wikidata are the only ownership traces available, with no public registry filing of beneficial ownership.
EFF's October 31, 2023 press release states that GoGuardian, like Gaggle and Bark, gives schools and the company itself access to an enormous amount of sensitive student data, and describes it as by design a mass surveillance system that lets school officials track trends in student search histories, identifies supposedly 'at risk' students, and gathers location data on where and when a device is used, letting anyone with access to the data build a comprehensive profile of students on devices with the software installed.
GoGuardian's Product Privacy Policy states that it does not sell Personal Student Information, does not use it to target advertisements or to build a profile of a K-12 student for a non-educational purpose, does not sell or share School Information for cross-context behavioral advertising (and has not in the past 12 months), shows no advertisements in any of its products, and retains Personal Student Information as directed by the school, acting on documented deletion instructions subject to legal-obligation, law-enforcement, dispute, and contract-enforcement exceptions.
GoGuardian's Privacy and Trust page states the company is certified for an Information Security Management System compliant with ISO 27001:2022 and SOC 2, and is independently certified as FERPA and COPPA compliant by iKeepSafe; these are the company's own statements of third-party certification, and the certifying bodies for ISO 27001 and SOC 2 are not named on the page.
On October 31, 2023 the Electronic Frontier Foundation unveiled the Red Flag Machine, an interactive quiz and report derived from real GoGuardian data, after an investigation of GoGuardian, which the company says is used to monitor about 27 million students, mostly in middle and high school, in about 11,500 U.S. schools; EFF found the software regularly flags non-explicit content as harmful, including college application sites, counseling and therapy sites, drug-abuse information, LGBTQ+ issues, sexual health, gun violence, historical topics, and political parties, and that students were flagged for researching Black authors, the Holocaust, and the LGBTQ+ rights movement.
The Record reported on November 1, 2023 on EFF's investigation, repeating that GoGuardian is used to monitor about 27 million students in 11,500 schools and consistently flags innocuous content such as college websites, counseling sites, and pages about LGBTQ+ issues and sexual health; a GoGuardian spokesperson defended the product, saying schools have a responsibility to keep students safe in digital spaces and on school-issued devices and that GoGuardian lets educators block harmful or explicit content as required by federal law while allowing legitimate education tools.
EFF's June 22, 2023 post states that student-monitoring tools scan web pages, cloud-drive documents, emails, and video for keywords about sex, drugs, and violence; that many flagged terms are ambiguous and sweep in benign content; that numerous reports show regular flagging of LGBTQ+ content creates a harmful atmosphere and has outed some students; and that, per EFF's correspondence with the company, GoGuardian (like Gaggle) has removed LGBTQ+ terms from its keyword list, a step EFF commends while noting LGBTQ+ resources are still commonly flagged for words like 'sex' or 'breasts'.
EFF's investigation describes GoGuardian's Beacon tool as using machine learning and AI to monitor student behavior for flagged key terms, track history, and produce analysis of a student's likelihood of harming themselves or others, and reports that, using data from multiple schools in both red and blue states, GoGuardian's keyword flagging produced false positives that heavily outweighed accurate detections, flagging tens of thousands of students for benign or educational content across categories including college sites, counseling and therapy sites, LGBTQ issues, sexual health, gun violence, historical topics, and political figures.
