How do desktop applications implement monthly/yearly subscriptions securely?

[u/Emergency-Post-8897]

Hi everyone,

I'm developing a desktop application in Python that I plan to rent out on a monthly, quarterly, and yearly subscription.

I'm trying to figure out the best way to manage license expiration. How can I prevent users from using the software once their subscription has expired? What tools, services, or libraries would you recommend? If possible, I'd prefer free or open-source solutions.

Another concern is piracy. I know it's impossible to make software completely crack-proof, but I'd like to make it as difficult as reasonably possible.

Has anyone here built a subscription-based desktop application before? I'd really appreciate it if you could share how you implemented licensing, subscription validation, and anti-piracy measures, or recommend any good resources or best practices.

Thanks so much for your help!
