Leave nothing unsaid.
Write letters, notes, and legacy messages for your children, partner, or grandchildren. Choose exactly when they're delivered — privately, on your terms.
Rich text, photos, videos, and documents — alongside your words.
A look inside
Built for the words worth waiting on.
No ads. No noise. Just the screens you'll use to write, schedule, and trust your letters to arrive.
How it works
Three steps. Total control.
Write your message
Open the editor and write what matters — formatted, revised, on your timeline. Add photos, videos, audio, or documents alongside your words.
Set your conditions
Choose a date, set a reminder window, and update or cancel any time before delivery. The trigger is yours to control.
It's delivered — privately
Your recipient receives it privately. You remain in full control until the moment it matters.
Features
Everything you need. Nothing you don't.
Rich text. One recipient at a time. Full control.
Compose messages with rich text formatting and schedule them for any future date. Each message goes to one recipient and is managed independently — write a different one for everyone you have something to say to.
Use cases
The messages that matter most.
Legacy messages for children
“A letter to your child, delivered on their 18th birthday — written when they were too young to understand.”
Partners
“Final financial instructions for a spouse, locked until they're needed, impossible to intercept.”
When illness changes things
“A message of love, written while you still can — sent only when the time is right. Because some things are easier to say when there's nothing left to lose.”
Messages for grandchildren
“An annual message arriving on the same date every year — your words in their inbox, long after you might be there to send them.”
What's next
What's coming next.
Annual Recurring Messages
Send the same message every year — a birthday letter, an anniversary note, a reminder of love — delivered automatically, on schedule, forever.

Security architecture
Your words are yours. Full stop.
Privacy is a posture, not a feature toggle. We've built TimeLock around the assumption that what you write is yours, not ours — encrypted in transit and at rest, kept behind strict access controls, and free of the advertising networks that monetize content everywhere else.
Read the full privacy policy →Encrypted in transit
All client–server traffic uses TLS. Anything we receive over the network is encrypted on the wire.
Encrypted at rest
Stored files use AES-256 encryption at rest. We use industry-standard cloud storage with default encryption enforced at the bucket level.
No routine access to your content
We don't read your messages. Internal access is restricted to a need-to-know basis for support and reliability work, not for browsing.
No ads, no data sales
TimeLock is paid by users, not advertisers. We don't sell your data to anyone — ever. Your content stays yours.
