Terms of service
Effective date: October 3, 2026. Businesses also accept the business terms.
These terms are between you and Mike Garrett, doing business as MailKey ("MailKey", "we"). By creating an account you agree to them. Our privacy policy explains how we handle your data.
The service
MailKey gives each person a short key. Whoever you give it to can type it in, see a masked preview, and after claiming the record receive your exact name and current mailing address. When you move, you update your address once and everyone you have shared with receives the new one on the date of the move.
Free for people
MailKey is free for individuals.
Your account
- Accounts are held by adults. An account can also manage a household, including children and other dependents, and the adult who manages a child is responsible for that child's key.
- Give MailKey your real name and your real address. MailKey standardizes the address but does not verify that you live there, and you are responsible for keeping it accurate.
- MailKey asks you once a year to confirm your address. Keep your sign-in methods to yourself.
- If you connect an AI assistant, you are responsible for it. That includes what it does with addresses other people shared with you, which you may use only to deal with them yourself.
Your control
You decide who holds your address. You can see everyone who has it, revoke anyone at any time, require approval before a claim, and rotate your key so the old one stops working. Sharing with a business or another MailKey user happens only through your key and only after they claim the record.
What you agree not to do
- Do not enter another person's name or address as your own, and do not enter an address you do not have the right to share.
- Do not try to guess keys, or use MailKey to look people up without their key.
- Do not interfere with the service or use it to harass anyone.
- Do not invite people you do not know, or use address requests to send unwanted email.
Leaving
You can export your data as JSON and delete a person or your whole account at any time. Deleting revokes every grant, notifies the businesses and people who held your address, and removes your personal data within 30 days. We may suspend accounts that abuse the service.
Beta
MailKey is in a free beta. It is provided as is and as available, without warranties of any kind, to the extent the law allows, and it may change, pause or contain errors. To the extent the law allows, MailKey is not liable for indirect or consequential damages, and its total liability to you is limited to US$100.
Governing law
These terms are governed by the laws of the State of Maryland, without regard to its conflict-of-laws rules. Any dispute is resolved in the state or federal courts located in Maryland, and you and MailKey consent to their jurisdiction.
