Question 1

What happens if the kitchen Wi-Fi goes down in the walk-in freezer?

Accepted Answer

ChillLedger relies on local-first engineering. The mobile client caches all temperature logs locally inside Expo SQLite on the device itself. Once a network connection is detected, offline logs sync automatically in chunked batches of 50 to prevent cellular bandwidth choke.

Question 2

Is ChillLedger officially compliant with FDA Food Code standards?

Accepted Answer

Absolutely. Standard § 3-501.11 of the FDA Food Code accepts digital temperature logging systems, provided they carry verifiable timestamps and are unalterable. Our Postgres trigger-based write-only table constraints ensure that historical log ledgers are completely immutable, fully satisfying regulatory audits.

Question 3

Does our kitchen require specialized or proprietary thermometer hardware?

Accepted Answer

No proprietary hardware is required. The mobile app's built-in OcrCamera overlay takes photos of any standard dial, digital, or liquid-glass display thermometer. Our in-memory Supabase Gemini Edge function parses the temperature instantly, keeping setup costs at zero.
