    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.

    GDPR Compliance
    HELD

    DeepL collects and uses your personal data exclusively within the framework of the statutory provisions, in particular the General Data Protection Regulation. Processing relies on legitimate interests (Art. 6(1)(f)) and explicit consent (Art. 6(1)(a)).

    Data processing agreement

    Data region

    EU (Germany, Cologne)

    Linguee is a translation dictionary and memory search tool, not an AI translation service. DeepL Translator (paid product) may use data for training with customer consent controls; Linguee dictionary does not perform model training—it simply searches a static corpus of parallel sentences.

    // Products & data scope

    Linguee DictionaryTranslation Dictionary / Reference Tool

    data: Search queries, IP addresses, browser metadata, cookies for ad personalization and analytics

    Free, ad-supported online dictionary. Not an AI translation model—provides bilingual example sentences and usage context from a static translation memory corpus. Users retain IP anonymization after 14 days.

    // What to watch

    • Identity-conflation risk: Linguee (free dictionary) is a distinct product from DeepL Translator (paid translation API). Parent company DeepL SE holds SOC 2 Type II, ISO 27001, HIPAA, and BSI C5 Type 2 certifications, but these apply to DeepL Translator, not the free Linguee dictionary.
    • Over-claim risk: Marketing or third-party sources may conflate parent company certifications with Linguee product scope. No evidence that Linguee dictionary inherits or requires these enterprise certifications.
    • No dedicated trust center or security page for Linguee product. All compliance documentation references parent company DeepL SE.
    • Linguee is a simple dictionary search tool, not an AI model. It does not train on user data. Maturity is 'startup' because Linguee generates ad revenue only; it is not a commercial SaaS product.
    • GDPR compliance is explicitly stated, but no independent verification (audit, certification document) is available on Linguee domain.

    // How we verified this

    Every certification marked HELD is confirmed against a verbatim quote on DeepL SE's own trust, security, or privacy pages. We reject certifications claimed only on third-party aggregators, on a cloud host's behalf, or by a similarly named company.

    Last verified 2026-07-07. Compliance changes over time. Always confirm directly with the vendor before relying on any certification for a purchasing or compliance decision.
