These are the terms for using muffl. We've tried to write them the way we'd want to read them — plainly, and only as long as they need to be.
By creating an account or using muffl., you agree to these terms. If you don't agree, please don't use the service.
muffl. is a tool for composing short, no-pressure "quiet update" postcards to send to people in your professional life — professors, mentors, former colleagues, and anyone else you don't want to lose touch with.
You're responsible for keeping your login credentials secure and for anything that happens under your account. Use a real email address you control — it's how your Received view and any account communication works.
Don't use muffl. to:
We can suspend or terminate accounts that violate this.
You own what you write. By using muffl., you give us permission to store your card content and display it back to you, and to the intended recipient, exactly as the product is designed to do — that's it. We don't use your messages for anything else, including training any kind of model.
"No response expected" is a design choice, not a promise about how any individual recipient will behave — they're free to reply if they want to. Likewise, because the final send happens in your own email client rather than through us, we can't guarantee a card was delivered, opened, or read. The "seen" indicator reflects whether the card's public link was opened, which is the closest signal we have.
muffl. is currently free to use. We may introduce paid plans or usage limits in the future. If we do, we'll tell you clearly before anything you're currently using becomes paid or restricted.
You can stop using muffl. and ask us to delete your account at any time (see the Privacy Policy for how). We may suspend or terminate accounts that violate these terms.
muffl. is an early-stage, independently-built product. We do our best to keep it reliable, but we don't guarantee uninterrupted uptime or that it will be bug-free, and it's provided without warranties of any kind.
To the extent permitted by law, muffl. and its creator aren't liable for indirect, incidental, or consequential damages arising from your use of the service, including a message not reaching its recipient, since delivery happens outside our systems.
These terms are governed by the laws of the Commonwealth of Virginia, USA, without regard to conflict-of-law principles.
We'll update these terms as muffl. changes, and update the date at the top when we do. Continued use after a change means you accept the updated terms.
