These Terms of Service ("Terms") constitute a legally binding agreement between you and Think Big Leaders AB, a company registered in Sweden with company registration number 559329-6105, located at Södermannagatan 37, Stockholm 11640, Sweden ("Castifai", "Company", "we", "us", or "our").

4. Subscriptions and Payments

4.1 Free and Paid Plans

Castifai offers both free and paid subscription plans. The free plan provides access to basic features with certain limitations. Paid plans ("Pro" subscriptions) provide access to additional features, including advanced AI image generation, voice customization, multi-language support, and LinkedIn integration.

4.2 Free Trial

New users may be eligible for a free trial of Pro features. The trial period and terms will be communicated at the time of registration. At the end of the trial period, your account will revert to the free plan unless you subscribe to a paid plan.
