Paid plans are not on sale yet

We do not take payments yet, and nobody has been charged for a plan. This page sets out the rules that will apply once paid plans go on sale. We will announce plans and prices on this site before then.

Cancelling

  • You can cancel a plan at any time by writing to contact@lumistrel.com. There is no cancellation fee.
  • Cancelling stops the next renewal. You keep your plan until the end of the period you already paid for.
  • Your drawings stay yours. You can export them before and after you cancel; see our terms for how long we keep saved drawings after a plan ends.

When we refund

SituationWhat we refund

You were charged twice, or charged the wrong amountThe amount charged in error, whenever you tell us.
You paid but your access did not start, or the service did not work as described and we could not fix itThe whole payment for the period affected.
We end your plan early without you being at fault, or stop offering what you paid forThe unused part of what you prepaid, worked out by days.
