Digital Haptic Tactility
Every number confirmation triggers advanced vibration damping feedback, creating a silky ritual sensation like fingertips gently touching the wall of a chilled glass.
Translucent Asset Flow Bubbles
Discarding traditional rigid red-green bar charts, introducing elegantly reorganized frosted glass flow bubbles — making every expense float and aggregate intuitively in macro space like crystalline particles in tea.

Clean Answers About the Blank Space
Why no automatic cloud sync?
Restraint translates into beauty, and offline design translates into trust. The data that will never leak is the data that never goes to the cloud. We return full control to you, eliminating all financial privacy anxiety caused by backend overreach.
How do I back up data when switching devices?
The app supports one-click export — instantly generating standards-compliant private JSON or plaintext CSV files. You can transfer them through your most trusted channels: AirDrop, encrypted cloud drives, or any physical method you prefer.
Will there be paid plans or financial recommendations?
Absolutely not. CaiBookkeeping is created by an independent developer driven by aesthetic obsession. There will never be any financial product placement. The premium local edition is a one-time purchase that remains locally usable forever — maintaining a noise-free, distraction-free pure experience.
