The App includes links that open external services (for example, the ChatGPT website) in a browser.

In the "AI Word Generate & Import" flow, the app may copy your input to the clipboard and open https://chatgpt.com/ in a browser.

Use of external services is governed by those services’ own terms and privacy policies.

The operator does not guarantee the accuracy or usefulness of content or results provided by external services.

The operator is not responsible for issues or damages caused by outages, suspension, or specification changes of external services.
