■ FAQ
Q. How often should I replace my toothbrush?
Every 3 months is the common recommendation — Reflow's presets already reflect
it, so register once and the reminder takes care of the rest.

Q. Can each item have its own replacement schedule?
Yes. Set a custom cycle in days for every item — shower filter, water filter,
air filter, anything.

Q. Where is my data stored?
Nothing leaves your device. All replacement history is stored locally — no
account, no sign-in.
