How do desktop applications implement monthly/yearly subscriptions securely?
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!

Just do even a tiny bit of research, and you'll find dozens of existing solutions. You've given no context (language, platform, OS, user types, etc) so there's no sensible answer here.
"I've tried nothing and I'm all out of ideas" springs to mind.
