Privacy policy: https://texthumanizer.pro/privacy

Humanizer PRO processes only text the user explicitly selects or pastes and submits for rewriting, plus account authentication information needed to keep the user signed in. Submitted text can contain personal identifiers or personal communications chosen by the user. The add-on does not collect browsing history, search history, location, financial data, health data, or background keystroke/activity analytics. Data is used only to provide the requested rewrite, maintain account access and enforce the user's plan and word balance. It is not sold or used for personalized advertising.
