Privacy policy.

We collect the minimum required to operate the service: account details (email, name), billing information (handled by Stripe — we never store card numbers), and the text you submit for humanization.

We never train our model on your inputs or outputs. We never sell, share, or rent your data to third parties. We never use your writing for advertising.

Free accounts: inputs and outputs are deleted after 3 days. Pro accounts: kept indefinitely so you can revisit history, with a one-click "purge everything" option in your settings.

We use functional cookies for authentication and a single first-party analytics cookie. We do not run third-party ad pixels.

Under GDPR and CCPA, you can export or delete all data we hold on you. Request from your account page, or email [email protected].

Humanizer is not intended for users under 13. We do not knowingly collect data from children.

These terms are governed by the laws of Portugal. Disputes shall be resolved in the courts of Lisbon.

We'll email you at least 30 days before any material change to this policy. Last updated April 28, 2026.
