# Free trial

> 30 days of full access to explore everything 3D Prep Pro offers

## How it works

When you subscribe, your first 30 days are free. You get full access to every feature — unlimited repairs, all tools, every export format.

<Steps>
  <Step title="Use your 2 free repairs">
    Try the platform with no commitment. Upload a model and repair it.
  </Step>

  <Step title="Start your free trial">
    When you're ready, go to the checkout page and enter your payment details. Your trial begins immediately.
  </Step>

  <Step title="Enjoy 30 days of full access">
    Use every feature without limits. Your card is not charged during the trial.
  </Step>

  <Step title="Automatic subscription">
    After 30 days, your subscription begins at your plan's monthly rate. Cancel anytime before the trial ends to avoid charges.
  </Step>
</Steps>

## What happens when the trial ends

* If you **keep your subscription**: You're charged the monthly rate and everything continues.
* If you **cancel before the trial ends**: You're not charged. Your account reverts to the free tier (2 repair limit, models preserved).
