Modules

  1. Quiet inventory

    Catalog wallets, plates, and paper without reading phrases into a mic or chat.

  2. Label language

    Create boring, consistent labels that help a partner without revealing content.

  3. Dual-location layout

    Choose Site A / Site B rules for apartments and travel bags common in Korea.

  4. Metal and paper care

    Handle stamping, ink, and humidity without improvising unsafe shortcuts.

  5. Partner rehearsal

    Time a recovery hunt using sealed cards; log gaps for the next edit.

  6. Maintenance cadence

    Install a quarterly review that fits ordinary calendars.

Instructor

Yuna Seo facilitates Apinode Core’s organizer curriculum from Daegu. Her sessions emphasize physical kits, readable printables, and a firm refusal to handle learner seed material. Previously she ran community study tables focused on household documentation habits.

Learner notes

The Module 5 timer made our first rehearsal feel less awkward. We still needed a second pass because Site B lighting was terrible—that limitation is called out in the FAQ, which helped set expectations.

Clear worksheets. I wanted more A5 print guidance on day one.

FAQ

Do I need special hardware?

No. A pen, envelopes, and a safe-ish household spot are enough to start. Metal plates are optional and covered later.

Will you store my phrase?

Never. Instructors will not accept phrases, photos, or cloud uploads of recovery words.

What is a real limitation of this course?

Phrase Ledger Foundations cannot replace a professional security assessment for high-threat scenarios. It also cannot fix a phrase that was already exposed online—you will need broader incident help outside this curriculum.
