Our 3-in-3 guarantee

We stand behind our product and are convinced that every healthy adult can achieve success with intermittent fasting.
For this reason we offer you a satisfaction guarantee according to the following conditions and will refund the full subscription price if you do not lose at least 3% of your body weight within three months.

Surely you know that in pursuing your goals, you have to follow rules, structures and habits consistently. Accordingly, it is important to observe and implement the following:

Our conditions for the 3-in-3 guarantee:

  1. We strongly discourage fasting for anyone who cannot do so without hesitation. Therefore, the guarantee is only valid for participants who are at least 18 years of age and have no medical indicators against fasting and who can fast without risk to their health. Pregnant women are therefore also excluded.
  2. Our satisfaction guarantee only applies to fully paid accounts. This means that the monthly costs of the account are paid and there are no chargebacks or refund requests or conflicts with your payment provider with us.
  3. You enter your actual weight in the Fastic App at least once a week.
  4. You fast with the 16/8 method or longer, but not more than 24 hours.
  5. You start and end your fasting timer every day¹.
  6. You have a maximum of six fasting-free days during the three months. You are free to set these up and decide when you want to take a break.
  7. If, despite the above points, you do not manage to lose 3% of your body weight within 3 months, we will refund the subscription price you paid to your means of payment.
  8. This satisfaction guarantee is subject to German law.
