    Data processing agreement

    Not stated

    Data region

    Primary processing in the United Kingdom; data stored on servers in the USA, with service providers also operating in the EEA and US. GDPR page: 'All ProWritingAid data is held on servers hosted outside of the EU in the USA.' Cross-border transfers covered by Standard Contractual Clauses (SCCs).

    ProWritingAid explicitly states it does NOT train its models on customer text. 'When using ProWritingAid, your texts will not be used to improve the quality of our services. We use texts hand corrected by professional copyeditors to train our algorithms.' Grammar-checked text is deleted after processing; only documents a user explicitly saves in the Web Editor are retained (encrypted) in the cloud. Trust Center: 'Our writing suggestions use our unique Natural Language Processing models that never retain your text.'

    // Products & data scope

    ProWritingAid Web EditorConsumer/web writing editor

    data: Pasted/uploaded text analyzed and discarded after processing; documents explicitly saved are encrypted and stored in the cloud.

    Core consumer experience for individual writers.

    Integrations (MS Word, Google Docs, Scrivener, Chrome/Firefox/Edge extensions, Desktop app)Plugins / browser extensions / desktop

    data: Text segments transmitted to ProWritingAid cloud NLP service for analysis and returned; not retained.

    Works inside the user's existing writing apps; same no-retention/no-training posture.

    Premium / Pro consumer plansPaid subscription

    data: Adds billing/payment data (handled by Stripe/PayPal) on top of writing data.

    Monthly, yearly and lifetime license options historically offered.

    Teams / Business and APITeam and developer/API access

    data: Business contact and configuration data collected for partners/customers; API exposes the same NLP analysis engine.

    Limited public detail on a distinct enterprise data/compliance scope; warrants direct confirmation for B2B procurement.

    // What to watch

    • SOC 2 language is aspirational/in-progress ('engage with third party auditors to assess our SOC 2 Security compliance') rather than a confirmed report; no report date, scope, or attestation published. Treat as NOT a held certification.
    • No ISO 27001 and no managed bug-bounty platform (HackerOne/Bugcrowd); only an ad-hoc security-report submission link.
    • Strong, clear no-training and no-retention stance on customer text is a positive differentiator versus many competitors.
    • Privacy Policy is current (last modified 04-Mar-2026) but the GDPR page is stale (last modified 28-Oct-2020), creating minor freshness inconsistency.
    • Data stored in the US under SCCs; no customer-selectable data residency. DPA availability not documented publicly.
    • Terms of Service URL inferred from site footer navigation, not directly fetched.

    // How we verified this

    Every certification marked HELD is confirmed against a verbatim quote on Orpheus Technology Limited (ProWritingAid)'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 2026-06-27. Compliance changes over time. Always confirm directly with the vendor before relying on any certification for a purchasing or compliance decision.
