Hello,

Hope you are well. We have recently completed our first online experiment on Prolific using otree, otree HR and Heroku. Now that our experiment is over, we plan to stop using all the paid services on these platforms till we run another experiment. I believe I have deleted the paid add-ons on Heroku like Redis, the paid Dynos and have made similar changes on otree. But being new to the platform and also being keen on not having to incur more money, I would like your advice on what else we need to do to avoid incurring any further charges on these platforms? There may be still some more steps I am not fully aware of.
