Terms of service
Last updated October 29, 2026
These terms cover your use of ImpromptuPost (the app, the website, and the ImpromptuPost connector for AI assistants). By using it you agree to them.
What we do
We suggest cards for moments we find or that you add, draft the messages, and, when you approve a card, have it written with a pen and mailed. Suggestions and drafts can be wrong: you decide what is sent.
Your account
You need an account to use ImpromptuPost and must be at least 18. Keep your sign-in secure; you're responsible for cards approved from your account.
Your content
You own your messages, pictures, signature and the information you add. You give us permission to use them only to run ImpromptuPost: to draft, show, write and mail your cards. Only send cards you have the right to send, and don't use ImpromptuPost to harass anyone or to send anything unlawful.
Plans and payment
Plans renew monthly until you cancel; you can cancel or change your plan any time in Settings, effective at the end of the billing period. Extra sends don't expire. A card cancelled before it goes to the writer is refunded as a send; once it's being written it can't be recalled.
We aim to mail cards in time for the date shown, but delivery depends on the postal service and on the address you give us. We're not responsible for postal delays or wrong addresses.
AI assistants
If you connect Claude or ChatGPT, it can suggest cards and read your upcoming card calendar; it can't approve, mail or pay for anything. Your use of that assistant is also governed by its own provider's terms.
Changes and ending
We may update ImpromptuPost and these terms; we'll tell you about significant changes before they apply. You can stop using ImpromptuPost and delete your account at any time. We may suspend accounts that break these terms.
The fine print
ImpromptuPost is provided as is. To the extent the law allows, our total liability for any claim is limited to what you paid us in the 12 months before it. Nothing here limits rights you have under consumer law.
