ProWritingAid

ProWritingAid explicitly states that user texts are NOT used to train their AI models. The company clearly commits that analyzed text is deleted after processing and that texts will not be used to improve service quality, distinguishing themselves from competitors.

“[ToS] "When using ProWritingAid, your texts will not be used to improve the quality of our services." [Privacy] "We use texts hand corrected by professional copyeditors to train our algorithms to ensure that our data is of the highest quality."”

ProWritingAid explicitly states users retain full ownership of all content and the company claims no rights to uploaded documents. The license is strictly limited to service delivery with no sublicensing or perpetual rights claimed.

“[ToS] "You retain ownership of all content you post, upload to, or otherwise share on the site." [Privacy] "We do not retain any rights to any of the documents or other content uploaded into our system."”

ProWritingAid explicitly states they do not sell, trade, or transfer personally identifiable information to outside parties except for essential service providers under confidentiality agreements. Non-personally identifiable data may be shared for analytics but not user content.

“[Privacy] "We do not sell, trade, or otherwise transfer to outside parties your personally identifiable information. The only exceptions to this rule are: Third parties who assist us in operating our website, conducting our business, or servicing you, so long as those parties agree to keep this information confidential."”

While ProWritingAid states analyzed texts are deleted after processing and saved documents are encrypted, the privacy policy uses vague language about retention ('as long as required to comply with obligations') without specific timeframes. Account deletion results in files marked for deletion in 60 days, which is reasonable but not immediate.

“[ToS] "Upon canceling your account, your files will be marked for deletion in sixty days, and will be deleted upon expiration of that sixty-day period." [Privacy] "We may keep some of your data for as long as it is required to comply with our obligations including law, tax and auditing."”

ProWritingAid explicitly confirms that users own all generated outputs and the company retains no rights to documents or content. Users have full ownership and control over their work product.

“[ToS] "You retain ownership of all content you post, upload to, or otherwise share on the site." [Privacy] "You retain ownership of all content you post, upload to, or otherwise share on the site."”

ProWritingAid mentions GDPR compliance, COPPA compliance, and CCPA compliance in their policies, and describes security measures including encryption and SSL. However, no formal certifications (SOC 2, ISO 27001, HIPAA) are explicitly mentioned, and no dedicated trust/security page is referenced.

“[Privacy] "We protect data using industry-standard measures including encryption in transit (TLS), encryption at rest where appropriate, access controls, role-based permissions, multi-factor authentication for administrative access, logging and monitoring, vulnerability management and regular security testing." [Privacy] "We are in compliance with the requirements of COPPA (Childrens Online Privacy Protection Act)"”
