    Quizlet

    Quizlet is a consumer/education flashcard and study platform (free tier + Quizlet Plus subscription) with classroom features for teachers and students (Quizlet for Classes). It previously offered an AI tutor, Q-Chat, built on the OpenAI API, which has since been discontinued (as of mid-2025 per public reporting). No separate enterprise/API product tier or dedicated healthcare offering was found.

    // Certification ledger

    Each held certification is backed by a verbatim quote from the vendor's own trust or security page. “Not confirmed” means we could not verify it publicly, not that the vendor lacks it.

    > Show 8 unconfirmed / not-held certifications
    SOC 2 (Type 1 or Type 2)
    NOT CONFIRMED

    No public evidence. Quizlet has no dedicated trust center; extensive search of quizlet.com, help.quizlet.com, and third-party compliance trackers found no SOC 2 report, badge, or reference.

    ISO 27001
    NOT CONFIRMED

    No public evidence found on any Quizlet-owned domain or in independent coverage.

    ISO 27017 / 27018 / 27701
    NOT CONFIRMED

    No public evidence found.

    ISO/IEC 42001 (AI management system)
    NOT CONFIRMED

    No public evidence found. No AI-governance certification referenced anywhere on Quizlet's site or help center, despite Quizlet shipping AI features (former Q-Chat tutor, Magic Notes, etc.).

    CSA STAR
    NOT CONFIRMED

    No public evidence found.

    HIPAA
    NOT CONFIRMED

    No public evidence of a HIPAA compliance program or BAA offering. Quizlet is a general consumer/education product, not a healthcare product, so HIPAA is likely out of scope rather than a gap.

    PCI DSS
    NOT CONFIRMED

    No public evidence found. Quizlet Plus billing is a small subscription flow; no PCI attestation is published, and payment processing is most likely handled by a third-party processor (unconfirmed).

    FedRAMP
    NOT CONFIRMED

    No public evidence found; not a government-focused product.

    // Privacy & AI training

    Trains on customer data

    Not stated

    Data processing agreement

    Not offered

    Data region

    Not confirmed publicly. Quizlet's GDPR help-center article describes transferring personal data from the EEA to the US using EU-Commission-approved mechanisms (Standard Contractual Clauses), implying primary data processing and storage in the United States.

    Whether Quizlet trains its own models on user-generated study content (flashcard sets, answers) is not confirmed by vendor-domain evidence. Quizlet's AI features (formerly Q-Chat, an AI tutor 'built with OpenAI's ChatGPT API' per Quizlet's own 2023 blog post title) rely on third-party model providers (OpenAI) rather than a Quizlet-trained model, based on available reporting; Q-Chat itself appears to have been discontinued (public reporting indicates it was no longer available as of mid-2025). No explicit AI-training opt-out mechanism or AI-specific data-use page was found.

    // Security controls

    Encryption in transit / at rest

    Quizlet's privacy policy states Quizlet 'uses reasonable efforts to follow generally accepted industry standards to protect personal information submitted to it, both during transmission and after receipt.' This is a general best-efforts statement, not a specific encryption-standard disclosure (e.g. TLS 1.2+/AES-256).

    Vulnerability / abuse reporting contact

    A security contact email (security@quizlet.com) is referenced in Quizlet's privacy policy, suggesting Quizlet accepts security reports, but no public bug bounty program or responsible-disclosure page was found.

    quizlet.com

    International data transfer mechanism

    Quizlet's GDPR help-center article describes use of EU-Commission-approved transfer mechanisms, including Standard Contractual Clauses, for EEA-to-US transfers. The same article also references the EU-US and Swiss-US Privacy Shield Frameworks, which were invalidated (Schrems II, 2020) and later superseded by the EU-US Data Privacy Framework (2023); citing 'Privacy Shield' verbatim would be stale legacy language.

    help.quizlet.com

    Trust center / compliance documentation portal

    None found. No trust.quizlet.com, security.quizlet.com, or equivalent portal exists; no downloadable SOC 2 report, security whitepaper, or subprocessor list was located.

    // Products & data scope

    Quizlet (free)Consumer study/flashcard app

    Data it handles: User-generated study sets, account/profile data, usage/study activity (some profile and activity data may be publicly visible per the product's social features).

    Data it handles: May include minor (K-12 student) data where used in schools; teacher-managed class rosters and student study activity.

    No dedicated COPPA/FERPA compliance page or Student Privacy Pledge signatory confirmation was found on Quizlet's own domain, despite the product's wide use in K-12 settings.

    Q-Chat (AI tutor, discontinued)AI feature, formerly built on OpenAI's API

    // What to watch

    • No trust center and no evidence of SOC 2, ISO 27001, HIPAA, PCI DSS, ISO 42001, CSA STAR, or FedRAMP anywhere on Quizlet's own domain or in independent coverage. This is normal for a consumer-focused edtech product, but no compliance badges should be shown.
    • Possible stale legacy reference to the invalidated EU-US/Swiss-US 'Privacy Shield' framework in Quizlet's GDPR help article; Privacy Shield was struck down in 2020 and replaced by the EU-US Data Privacy Framework in 2023. This could be an outdated document rather than an active claim.
    • No confirmation found of COPPA/FERPA-specific compliance messaging or Student Privacy Pledge signatory status, despite Quizlet's significant use in K-12 classrooms.
    • AI-training posture (whether user-generated flashcard content is used to train Quizlet's own models, and whether any opt-out exists) is not documented in vendor-domain sources.
