How much does Chrono charge?

Could you please clarify for me, what exactly is the pricing structure for Chrono? Are there any fees associated with using the platform, and if so, how are they calculated? I'm particularly interested in understanding if there are any hidden costs or ongoing subscription fees that I should be aware of. Additionally, does Chrono offer any discounts or promotional offers for new users, or for those who refer others to the platform? I appreciate your assistance in helping me understand the full financial implications of utilizing Chrono's services.
