Stays on this device. A formula card per client — brand, mix line, developer, time, results. Optional photo memo (auto-resized, stays on device). Replace the binder, skip the salon-software subscription. Be aware: clearing browser data clears this — export periodically for safety, or pin the tab.

Clients

Add a client to start logging formulas. You'll get a per-client formula history and the option to attach a small memo photo.

About the data. Everything — client names, formulas, photos — is stored only in this browser's localStorage. Photos are auto-resized to ≤600px on the long edge to keep the storage budget reasonable. Clearing browser data, switching devices, or using a different browser will not see this data. For long-term safety, periodically copy the formulas you can't afford to lose into your usual notes app.
