Personal letters
A message to someone you love — a child, a partner, a friend. Delivered if you're ever unable to send it yourself.
Now in early access
Your most important messages,
delivered if you can't be.
SilentPost is a private vault for letters, files, and final instructions. Assign recipients and set a check-in schedule — if you stop responding, everything is delivered securely to who you chose.

The protocol
Simple by design.
Three steps. Then SilentPost handles the rest.
Who it's for
For anyone with something important to say.
Final instructions
Account credentials, legal notes, medical wishes, or last requests — in the right hands, at the right moment.
Business continuity
Instructions for your team, partners, or co-founders to handle critical matters if you become unavailable without warning.
Digital estate
Passwords, seed phrases, private documents — passed on to a trusted person without lawyers or intermediaries.
Security & privacy
You stay in control.
SilentPost is designed to hold sensitive content. Every decision reflects that.
Encrypted storage
Your content is encrypted at rest on our servers. All access to stored content is logged and independently audited by third-party monitors in real time — creating a verifiable record that it has never been accessed outside of delivery.
Minimal identity exposure
No real name required. Pay with crypto. Designed to minimize the data we hold about you without sacrificing delivery reliability.
One-time access links
Every delivery link works exactly once. After the recipient opens it, the content is immediately purged from our servers — permanently and irreversibly.
Revocable until delivery
Delete any message at any time before delivery begins. Once sealed, only your intended recipient will ever see it — and only if and when the trigger fires.
The vault
Clean. Private. Purposeful.
Designed to stay out of your way until it matters.

FAQ
Common questions.
If you miss your check-in reminder and the subsequent grace period you set, SilentPost sends each recipient their secure access link. The grace period gives you extra time in case you're traveling or temporarily unreachable.
Yes. Until delivery begins, you're in full control. Check in at any time to reset your schedule, extend your grace period, or delete messages you no longer want sent.
Text messages, images, video files, and documents. Each message can include multiple attachments. Every plan includes 2 GB of encrypted storage shared across all your messages.
Your messages are stored using end-to-end encryption. All server access is independently audited in real time by third-party monitors — producing a verifiable, tamper-evident log that your content has never been accessed outside of the delivery process.
If you pay with crypto, we require no personal information to create an account. We've designed the platform to minimize the data we hold about you while maintaining delivery reliability.
SilentPost is fully automated — delivery requires no human intervention. The platform runs lean, with minimal infrastructure and no operational dependencies. There are no employees, offices, or business overhead that could create pressure to shut down. It's designed to run indefinitely, exactly as intended, for as long as the messages inside it need to wait.
No. Delivery links are one-directional and single-use. Once opened, the content is permanently inaccessible. SilentPost is not a conversation platform — it's a record of what you chose to leave behind.
