HOW IT WORKS

How secure offline data storage works.

We’ve learned the cleanest boundary is also the simplest. You choose the media and encrypt it — the password never leaves your hands. Everkeep handles everything physical: intake, verification, sealing, and separate storage. Encryption is your job. Custody is ours.

STEP / 01

Choose two matching devices

Prepare a primary and backup suitable for long-term storage. Both should contain the same encrypted data.

STEP / 02

Encrypt both copies yourself

Use full-volume encryption and keep the password and recovery information somewhere safe and separate — somewhere that isn’t the drive itself. Seneca wrote that we suffer more in imagination than in reality; a written-down recovery key, stored apart, turns imagined disaster into a solved problem.

STEP / 03

Package and ship

Follow the intake guide, record the device serial numbers, and send both copies to your designated receiving address. Five intake centers worldwide — New York, Toronto, Tokyo, Beijing, Seoul — and we confirm the nearest one when you enroll.

STEP / 04

Intake, number and photograph

Everkeep records each manufacturer serial number, assigns an EK-YYYY-NNNN custody number, applies a numbered seal and photographs the sealed media.

STEP / 05

Separate offline custody

The primary and backup are stored in different locations. Facility security is monitored; the media stays disconnected from every network.

THE EVERKEEP SEAL

Every handoff produces evidence.

The brass seal is more than a visual signature. It connects the public promise to an operating record: custody number, manufacturer serial, close-up seal image and full-device photographs.

Intake confirmation

Custody ID · device serial · seal status · intake photographs · primary/backup location record · verifier sign-off

AFTER INTAKE

What you receive, twice a year.

01 / RECORD

Custody confirmation

A record tying your device to its custody number and seal evidence.

02 / CHECK

Condition report

A hands-off physical inspection — seal, condition, inventory. We never power on your drive without your written consent.

03 / REMIND

Renewal notice

Clear notice before the next custody period begins.

INTAKE CENTERS

Five cities. One nearest you.

New York · Toronto · Tokyo · Beijing · Seoul. After you enroll, we’ll confirm the receiving address nearest to you — no intercontinental shipping, no guesswork.

Receiving addresses are intake points only, and they are not where your media is stored. Your drives rest in separate secure offline vaults — and we never disclose which vault holds whose media.
