## What is Hazedoki Roastery?

Hazedoki is a roast-lot ledger for independent coffee roastery owners.

From green-bean purchasing to roasting, inventory, and cost calculation — built so an owner can open the books and show the tax office, the bank, or family exactly how every number was computed.

What it does:
◆ Green lot ledger — record variety, origin, supplier, quantity, and purchase price (tax included). Remaining stock is computed automatically from summed deltas
◆ Roast log — record charge, drop, and roast level to instantly see roast loss and roasted-bean cost (per 100 g). Log the turning point, first and second crack, plus gas pressure and damper settings
◆ Inventory — green and roasted beans both use append-only intake/outtake entries. No separately maintained "current value", so the numbers never drift
◆ Cost & margin — per bag or drink: bean cost, packaging, sale price, margin and margin rate. Supports reduced (8%) and standard (10%) tax rates; all internal math is tax-exclusive
◆ Price-increase simulation — when bean prices rise, find the sale price that protects your margin
◆ Same-condition comparison — compare the current roast with past roasts at matching humidity and room temperature
◆ CSV export — roast logs and green lots in a form any spreadsheet app can read
◆ JSON backup — export and re-import everything. Ready for device migrations and sync accidents

About the numbers:
・Amounts are handled as Decimal and never rounded mid-calculation (rounding happens only at display)
・Stock is derived from summed deltas — no silently drifting current-value bookkeeping
・Values that cannot be predicted are shown as unknown. Never fabricated

Sync & privacy:
・Syncs only between your own devices via iCloud (CloudKit). No servers, no account sign-up
・The free tier includes roasting, costing, and CSV export. A one-time purchase removes the record-count limits

## Version history (last 3 releases)

### 1.0.2 — 2026-08-16

Restored the coffee bean app icon used in version 1.0. Version 1.0.1 shipped an older draft icon by mistake, so this update puts the original back. No functional changes.

### 1.0.1 — 2026-08-15

The cost breakdown now shows amounts to the sen (two decimal places). They were previously rounded to whole yen, so the bean cost and packaging cost did not add up to the displayed total when checked with a calculator. This screen exists to explain your pricing to someone else, so the arithmetic now adds up as shown.

### 1.0 — 2026-08-14

No release notes.
