If Something Happens to You, Your Family Gets Everything. Automatically.

You can reset it. Request a password reset link from the sign-in page and we'll email it to you - no recovery codes to keep track of. Your files stay encrypted at rest the whole time.

Everything you store is protected with AES-256-GCM encryption — files are encrypted at rest the moment they're stored, and in transit on the way there. Learn more on our Under the Hood page.

Yes — but you won't be charged until your 30-day trial ends, and you can cancel anytime in one click. We'll email you before your trial ends.

Every plan comes with a 30-day free trial — a full month to try everything, and you can cancel anytime before the trial ends without being charged. After that, monthly plans simply 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.

Your data is never locked in. You can download every file you've stored at any time, so you always hold your own copy independent of us. And because everything is encrypted with keys only you control, the only people who can ever read your files are you and the beneficiaries you choose. The automatic delivery does depend on the service running, which is exactly why we keep your files fully exportable. We recommend downloading a copy of your files periodically. If we ever wind down, we commit to at least 6 months' notice and a guaranteed export window.

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.

Yes. When you set up a switch, choose "On a date" instead of a check-in schedule and pick the exact date and time in your timezone. You'll get reminders 7 days, 3 days, and 1 day out, plus a final heads-up 3 hours before it fires — and you can edit or pause it any time until then. No check-ins required, which makes it a natural fit for a birthday letter, an anniversary message, or documents you want released on a specific day.

Your files are encrypted at rest and in transit. A file only becomes accessible to a beneficiary in three cases you control: you share it, you add it to a deadman switch, or you mark it AI-readable for a connector session. When you add a file to a deadman switch or create a share link, a unique key is generated for that specific share, so you can revoke any one at any time without affecting others. All share access is logged with IP and location for full transparency. Learn more on our Under the Hood page.

Only the files you choose, and only when you say so. Files are private by default — Claude cannot read them unless you mark them AI-readable (we call this Standard mode), which lets Claude read them during a session you start. Access is held only in memory, only for that session, and is dropped the moment the session ends. You can grant or revoke AI-readable access to any file at any time, and it's instant: nothing is re-uploaded. Learn more on our Under the Hood page.

Your data is never deleted when you cancel. At the end of your billing period your vault becomes read-only: you can still log in, view and download everything you've stored, and keep checking in to your deadman switches — you just can't add new files or edit switches until you resubscribe. If you have an active switch with items and beneficiaries, your account stays alive indefinitely so the switch can still fire on schedule. Cancelling alone never schedules deletion — we only do that when we can no longer deliver email to your account (repeated hard bounces), and we send several warning emails first.
