Your Family Shouldn't Need a Lawyer to Find Your Will.

During registration, you'll receive recovery codes that can restore access to your account. Store these safely - they're your backup if you forget your password. Due to our zero-knowledge architecture, these codes are the only way to recover access. Watch our registration walkthrough in the How It Works section to see how it works.

We use the same encryption architecture as 1Password and Bitwarden - AES-256-GCM encryption with keys derived from your password. Files are encrypted in your browser before upload. Learn more on our Under the Hood page.

Starter comes with a 7-day free trial — try it risk-free and cancel anytime before the trial ends. Yearly plans include a 30-day money-back guarantee: full refund within 30 days, no questions asked. Monthly plans cancel at the end of the current period — you're never on the hook for more than one month at a time.

Your deadman switch still fires. Once you've set up a switch with documents and beneficiaries, it triggers on schedule regardless of subscription status — that's our always-fires guarantee. While your subscription is inactive your account becomes read-only (you can still log in, view, download, and check in via email/SMS reminders), but you can't upload new files or modify switches until you resubscribe. Your existing files and switches stay protected indefinitely.

Any file type - PDFs, images, documents, spreadsheets, and more. Common uses include wills, insurance policies, tax documents, and family photos.

When a deadman switch triggers, beneficiaries receive a unique secure link via email. They don't need a Killswitch account - they can download their assigned files directly.

There is a grace period you can set to give you extra time to check-in. If one does trigger and you didn't want it to, you have full control of the share links and can revoke them immediately.

Files without any shares or deadman switches are fully zero-knowledge — we cannot access them. When you add a file to a deadman switch or create a share link, a unique encryption key is generated for that specific share and encrypted with our server-side vault so we can deliver it to your beneficiary. Each share has its own key, so you can revoke any one at any time without affecting others. All share access is logged with IP and location for full transparency. This is the same approach used by 1Password, Bitwarden, and LastPass for their emergency access features. Learn more on our Under the Hood page.

After cancellation, your account enters read-only mode at the end of your billing period. You can still log in, download files, and check in to your deadman switches — you just can't upload new files or edit existing switches. If you have an active deadman switch with items and beneficiaries, your account stays alive indefinitely so the switch can still fire on schedule. Accounts with no active switches may be removed after an extended period of inactivity, and we send several warning emails before that happens. You can resubscribe anytime to restore full access. Due to our zero-knowledge encryption, deleted data cannot be recovered.
