Write the words you keep meaning to say — and seal them for the day they'll matter
Tenderly lets you write letters to the people you love and seal them for a future date — tomorrow, an 18th birthday, a wedding morning, or the day they'll need them most. You write it today. They read it when it matters. A time capsule for the heart.
Sound familiar?
The Letter You Never Wrote
There are words you keep meaning to say — to your child, your partner, your parents. Life gets busy, the moment passes, and the letter stays unwritten until it's too late.
You Can't Be There for Every Moment
An 18th birthday, a wedding morning, a hard day years from now. You want them to hear from you exactly when it matters most — but you can't schedule your presence.
A Love Letter Deserves Better Than Notes
The most intimate words you'll ever write shouldn't live in a to-do app between grocery lists and reminders. They deserve a space that treats them as sacred.
Paper Time Capsules Get Lost
Handwritten letters fade, get misplaced, or never get delivered. There's no reliable way to make sure your words arrive on the exact day you intended.

Frequently asked questions
What happens to my sealed letters if I cancel?
Every letter you've already sealed will still be delivered on schedule — even if your subscription ends. Delivery happens on your device, so a letter you've scheduled arrives whether or not you still subscribe. Your subscription pays for writing new letters and family features, never to hold letters you've already sealed.
Are my letters really private?
Yes. Sealed letters are encrypted on your device with keys only you hold, so their contents stay private to you — even from us. Tenderly is local-first: it works offline and keeps your most intimate words between you and the person you wrote them for.
Who can I write letters to?
Anyone you love — your daughter, your son, your partner, your parents, a future grandchild. Pick the moment the letter should arrive, seal it, and let time do the rest. The countdown begins the moment you seal it.
How does delivery work?
You choose the exact date each letter should arrive — tomorrow, an 18th birthday, a wedding morning, or years from now. When the day comes, a quiet notice appears: a letter has arrived. No printing, no shipping, no waiting on the mail.
What's included in the free tier?
The free tier includes 1 sealed letter so you can feel what Tenderly does before you decide. Premium unlocks unlimited sealed letters, photos and media, and shared family journaling.
Is there a public feed or social features?
No. Tenderly has no public feed and no strangers — just a warm, private space for the people you love. Between the big letters, you can keep a private journal and choose what to share with family.
Write love that arrives later
Some words are worth the wait. Write the letter you keep meaning to send, seal it, and choose the day it arrives. Free to start — your first sealed letter is on us.
