An agreement you can
actually read.
Six short promises between you and us. They are the terms — written for the person trusting us with twenty years of letters.
What Dear Son is.
Dear Son lets you write letters — words, photos, voice, video — to people you love, seal them, and have them delivered at a time you choose: an age, a date, a milestone, or right now. We store sealed letters and watch the calendar so you don’t have to.
Dear Son is in early access. Things will improve and occasionally wobble. We’ll treat your letters as the precious cargo they are throughout.
Yours. Full stop.
Everything you write belongs to you. You give us only the narrow permission we need to operate the service: to store your sealed letters, back them up, move them between servers, and show them to the people you addressed them to, when you said to. We claim no other rights, and we never use your letters to advertise, train models, or anything of the kind.
Sealed letters are never held hostage.
If a paid plan lapses someday, your vault becomes read-only — but nothing already sealed is deleted, and every scheduled letter still unlocks on its day. We will never delete a sealed letter because of a billing state. Deleting letters is something only you can ask for.
Write like it will be read.
Use your real email so the vault can reach you. Write only to people you genuinely know — invitations and claim links are for them, not strangers. Don’t put anything unlawful in a letter, and don’t use the service to harass anyone. Letters are private, but they are not a place to hide things the law compels us to act on.
You must be an adult to hold an account. The people you write to can be any age — that’s the point — and may claim their own account later to read what you kept for them.
You can always leave with everything.
You can stop using Dear Son at any time, and you can ask for a complete export or permanent deletion of your account at [email protected]. We may suspend accounts that abuse the service or other people; even then, lawful sealed letters addressed to recipients remain deliverable unless their writer asks otherwise.
Honest limits.
We work hard to be dependable — sealed letters are stored redundantly and delivery is automated — but early-access software comes with no formal warranty, and our liability is limited to what you’ve paid us. Keep your own copies of anything you cannot bear to lose twice.
If these terms change in a way that matters, we’ll email you in plain language first. Last updated 11 June 2026.
