Since I’ve been learning workflow recently, does this mean you’re telling me you’ll delete it in 3 days? Then wouldn’t all my effort over these past ten days be wasted 
Hi @Lee_Lee1, welcome!
This means you are on your n8n cloud trial period, and it is about to end, and so you would not be able to access the flows until you pay for the subscription, and if you have not paid for over 90 days, your account and all of your flows will be deleted permanently. First export all of your workflows by:
And then consider paying for your n8n cloud plan.
Well, you can self-host (it’s free)
Thank you so much~~~HAVE A GOOD DAY
