SaaS founders - how do you handle cancellations?

I'm currently building a tiny tool to reduce churn for SaaS products using Stripe, something super simple:

But before I go too far, I’m genuinely curious...

How do YOU handle cancellations right now?

• Do you ask why they leave to improve your product?

• Do you offer a discount? A pause?

• Or just let them go?

Also:

• Have you ever tested different approaches?

• What’s one thing that actually worked for you to keep a user from leaving?

Would love to hear how you deal with it — I'm building this in public, and all feedback is gold
