Future DeliveryTime Vault is a message that cannot be opened before a date you choose. The use cases range from board-level strategy to letters for your children.
Locked by cryptography, not by trust. No one — including us — can open it early.
Time Vault is a message or document encrypted today that cannot be accessed until a future date you specify. The content is encrypted in your browser using AES-256-GCM before it reaches our servers. The decryption key is not released until the opening date — and even then, we do not have it. The key is stored in the link itself, which is delivered to recipients only when the date arrives.
Business use cases. Board-level strategy documents, sealed bids, succession plans, or executive communications that should only be opened after a vote, announcement, or quarter close. A Time Vault eliminates the risk of premature disclosure — the content is physically inaccessible, not just organisationally restricted.
Personal use cases. Letters written for a child to open at 18, an anniversary message prepared months in advance, a personal reflection to open in one year. The content is guaranteed to exist on that date without relying on any single person to remember to send it.
Legal and compliance use cases. Evidence preservation — documentation sealed before a legal process begins, timestamped and inaccessible to all parties until proceedings are concluded. Regulatory hold documentation where access restriction needs to be demonstrably enforced rather than merely promised.
What makes Time Vault different from a scheduled email is that the secrecy exists during the waiting period, not only at the moment of delivery. A scheduled email still sits in a provider account in readable form before it is sent. A properly encrypted capsule stays unreadable at rest, which matters if the storage system is breached months or years before the opening date.
Capsules that open within 30 days are free. For longer periods, a small fee covers storage costs. Recipients receive an email notification when the capsule opens.
For adjacent use cases, see sending an encrypted letter to your future self and how to send a message after death. They rely on the same privacy logic, but with different emotional and operational triggers.
Use cases
Time Vault is strongest when the waiting period itself is part of the security or emotional meaning of the message.
If a document should only be opened after a vote, quarter close, or strategic announcement, an ordinary scheduled email does not provide meaningful control. Time Vault enforces inaccessibility until the chosen date.
Letters to a child, anniversary notes, or personal time capsules matter only if they truly stay closed until the right moment. Here the value comes not just from delivery, but from the credibility of the waiting period.
In legal and compliance scenarios, Time Vault helps demonstrate that access restriction was enforced technically, not merely described in policy. That distinction matters when nobody should be able to read the material early.
Owners can delete a capsule from their dashboard before the opening date. You cannot modify the content or the opening date — both are fixed at creation.
This is a legitimate question for any long-term service. We store the encrypted content in a PostgreSQL database with regular backups. For very long timeframes, consider downloading your encrypted content and the link for offline storage.
Up to 20 years from the date of creation.
No. A scheduled email is usually stored in readable form by the mail provider before delivery. A Time Vault stores encrypted content that remains inaccessible until the opening date, so the waiting period itself is protected.

A letter to your future self is only meaningful if it stays unread, unchanged, and private until the date you intended. Encryption is what makes that credible.

A dead man's switch is not only for spy fiction or catastrophic scenarios. In encrypted form, it becomes a practical tool for continuity, succession, and last-resort disclosure.

If a final message matters, it should not depend on someone remembering a password or a mail provider keeping a draft safe for years. Encryption changes the model.
