About CalmSub
Why we built it
Subscription surprises are frustrating. You forget about a service, then months later you're surprised by charges you didn't expect. We built CalmSub to give you calm visibility into what's coming—no surprises, no judgment.
Calm by design
CalmSub shows you renewals before they hit, not after. This gives you time to act—cancel a trial, adjust a subscription, or prepare for a charge—without the stress of surprise bills.
No bank linking. You stay in complete control. No third-party access to your financial data.
No selling your data. We never sell, trade, or share your information. Privacy-first by design.
Built by NK Studios
CalmSub is built by NK Studios, a small team focused on creating tools that help people stay in control without adding anxiety. We believe software should be calm, clear, and respectful of your time and attention.
