Product Improvement and Training is on by default for individual users; can be switched off in the account. Help Center: 'Product Improvement and Training is on for individual users by default.' Privacy policy: 'We also use information we collect to train our AI models.' According to the privacy policy, AI service providers may not train on customers' user content.
- Pro (individual user; formerly Premium)
The same control applies to Free, Premium and single-user Pro, default on. Help Center: 'allows users ... to opt out of allowing us to use their content ... to train our models'. Non-content data (writing statistics) may continue to be used.
- Pro with multiple users / team account (self-service; according to the pricing page, Business features merged into Pro)
For accounts with more than one user, only the administrator changes the setting; default 'is enabled' (on). Help Center: 'Only admins can change the Product Improvement and Training setting for multi-user accounts.' Note: the Pro pricing page no longer lists 'Business' as a separate plan; the Help Center still refers to 'Grammarly Business'.
- Enterprise tier / accounts purchased through sales (Enterprise, Pro and Business via sales, Education)
Help Center: 'For all Enterprise-tier accounts ... Product Improvement and Training is off by default' (also Pro/Business accounts purchased via Sales and all Education accounts). Customer Business Agreement Section 5.4: 'will not use Customer Data to train any generative artificial intelligence models without Customer's prior written consent.' The DPA itself contains no training clause. Privacy policy: AI service providers may not train on user content.
