Locate
Confirm every device, seed medium, and secondary backup still lives where your map says it does.
Datalink Lab
A Hardware Wallet Routine Planner for quieter device days
Build a repeatable cadence for firmware checks, backup location reviews, and recovery drills — taught as habits, not one-off tutorials.
Flagship program
Cold Storage Cadence Lab
Six modules that turn sporadic wallet check-ins into a calendar you can keep. Inventory sheets, passphrase hygiene notes, and drill scripts designed for home desks in Korea and remote learners elsewhere.
A four-beat routine
Most people fail at cold storage hygiene because the steps live only in memory. We teach a short loop you can run monthly without turning it into a security theater.
Verify
Check firmware status, unused accounts, and whether receive addresses still match your records.
Drill
Run a timed recovery on a spare device or air-gapped practice wallet — never invent the drill on a bad day.
Log
Write what changed, what stayed, and what to revisit next cycle. Future-you is the audience.

What learners said after week three
“The Locate / Verify sheet from Cold Storage Cadence Lab exposed that my metal backup and paper copy disagreed on word 18. The module pacing felt slow until that moment — then the slowness made sense.”
“Useful calendar prompts. The firmware checklist assumes a bit more desktop comfort than I had on day one.”
“Yeongju office hours were short but specific. I finally scheduled a recovery drill instead of promising myself one.”
Why routines beat random tutorials
Memory is a weak vault
Device firmware, unused accounts, and backup locations drift. A written cadence catches drift before it becomes a crisis.
Drills without panic
Recovery practice on a calm Tuesday teaches more than improvising after a lost phone or failed cable.
Korea-aware logistics
We talk through apartment storage, travel to family homes, and how to keep maps accurate without broadcasting them.
Field notes
Short articles for people mid-routine — not generic crypto headlines.
