Privacy and terms

Last updated October 25, 2026

Greetmark is a business card you hand over in person. Your page is for everyone. Your card is for the people you meet. This page explains what we keep and who can see it, and the terms for using Greetmark.

Privacy

Who this covers

Three kinds of people use Greetmark: people who have a card (owners), people who meet a card by scanning its QR (visitors), and people who join the waitlist. A section below covers companies, for Greetmark for Teams.

If you have a card

What we keep

• Your sign-in email and your handle (greetmark.com/you).
• What you put on your card: name, title, company, photo, logo, bio, links, phone, website and any other email addresses you add.
• Where each detail goes: Public (on your page), Share in person (only for people who scan your QR), or Off.
• How your card looks and what it says: your look, greeting, messages and email wording.
• Your calendar address, if you connect one. It is a secret: we use it to suggest where you met someone, and we never show it or send it to any page.
• The contacts your card collects, with their chats and any photos shared in them.

Who can see it

Anyone can see the details you mark Public. Details you mark Share in person go only to people who scan your QR and chat with your card. Your contacts, chats and photos are for you alone: you see them once you're signed in, and we email you a copy of each new contact. The services listed below, and the people who run Greetmark, can reach them only to run the service.

If you meet a card

Visitors never sign up. When you scan someone's QR and chat with their card, we keep:

• What you type in the chat, including your name, email and anything you say about how you met.
• Any photo you choose to share in the chat.
• The date, and the event, if the owner's calendar shows one at that time.
• A cookie on this browser, so you can see the people you've met.

Who sees it: the person whose card you chatted with, because that is the point: it's how they remember you. And you. The services listed below process it to run Greetmark, and the people who run Greetmark can reach it when the service needs it.

How we use your email: to send you their card, and, if you click a link we sent, to confirm the address is yours. Typing an email unlocks nothing; only clicking our link does. We don't add you to a mailing list or send you marketing. Each card email ends with one link to get a card of your own, and that's all.

If you join the waitlist

We keep your email, the page you joined from and, if you met someone's card first, which card. We use them only to write when your spot opens.

Company data and personal data

A card always belongs to its person, never to a company. Greetmark for Teams, which isn't available yet, will let a company sponsor its people's cards. When it does:

• Contacts made on a card while a company sponsors it also go to that company, which keeps its copy under its own privacy policy. The person keeps the basics: who they met, how to reach them, and when.
• The chats on a sponsored card stay with the company.
• If the person leaves the company, they keep their card, and it stops showing the company's brand right away. The company keeps the contacts collected while they worked there. New contacts after that go to the person, not to the company.
• A visitor can ask the person, the company or us to delete their details.

We'll add the details here before Teams launches.

Services we use

We share data with these companies only to run Greetmark, and never for their own marketing:

• Cloudflare hosts Greetmark and stores its database and files.
• Resend sends our emails: cards, sign-in links and waitlist news. It keeps a copy of each email it sends for about 30 days.
• OpenAI writes the card's chat replies. To write each reply it receives the chat so far, the owner's card details and, if the owner's calendar shows one, the event's time and place. We ask OpenAI not to store chats, and under its terms for businesses it doesn't use them to train its models; it may keep them for up to 30 days to watch for abuse.
• Google Fonts supplies the typefaces on cards and public pages, so it sees the IP address and browser of anyone who opens one.

We would disclose data only if the law required it.

Cookies

We use only the cookies Greetmark needs: one that remembers this browser and the people you've met, one that keeps an owner signed in, and a short-lived one while you sign in. No advertising or analytics cookies.

How long we keep it

We clear out old records automatically, every few minutes.

• An owner's card and contacts stay until the owner deletes them. Deleting a contact also deletes its chat and photos.
• Deleting your account deletes your account and card, every chat, contact and photo on it, your looks, notes and calendar, your sign-in links and sessions, and the waitlist entry for your address. It doesn't delete another card's record of a chat you had with it as a visitor (that's their contact), or a chat where someone else typed your address.
• An unfinished claim for a card is deleted after a day.
• Sign-in links work once and expire: after 30 minutes for owners, after 30 days in card emails. We delete them 7 days after they're used or expire.
• A signed-in owner stays signed in for up to 400 days, renewed with use. Expired sessions are deleted.
• The "Did you meet…?" questions we ask when a card link opens on a new device are deleted 7 days after they're answered or expire.
• A page visit with no chat is deleted after a day.
• A browser record with nothing in it (no email, no chat, no card met) is deleted after 30 days.
• Calendar details are kept, encrypted, for at most an hour, and deleted at once when the owner changes or removes the calendar.
• For now, chats where the visitor never gave an email, and waitlist entries after an invite, stay until the card's owner deletes the chat or someone asks us to remove them. We'll set a time limit for both and publish it here.
• Copies outside our database can last a little longer before they're gone for good: our database backups and Resend's and OpenAI's records for up to 30 days, Cloudflare's logs for a few days.

Your rights

Wherever you live, you can:

• See what we hold about you. Owners see everything in their dashboard; anyone can ask us.
• Export it. Owners can download their contacts as a spreadsheet; anyone can ask us for a copy.
• Correct it. Owners can edit their card at any time.
• Delete it. Owners can delete a contact, or everything, from the dashboard. Visitors can ask the card's owner or us.
• Object to how we use it, or withdraw your consent, and we'll stop.

Write to us and we'll answer within 30 days. Laws such as Europe's GDPR and California's privacy law give some people these rights; we give them to everyone.

Security

Every request is checked against who you are, so one owner can never read another's contacts, and a chat can only be read or continued in the browser that started it (or, on a website that blocks our cookie, the open page that started it). Sign-in links work once and are stored scrambled. Photos from chats are never public. Greetmark's pages and the services behind it use HTTPS only; email travels between mail servers like any other email, usually encrypted. No system is perfect; if a breach ever affected your data, we would tell you promptly.

Children

Greetmark isn't meant for anyone under 16, and we don't knowingly keep their data.

Changes

If we change this policy, we'll post the new version here with its date, and email owners about anything important.

Terms

Draft for review. These terms aren't in effect yet.

Greetmark is a business card you hand over in person. These terms cover using it: having a card, and chatting with someone else's. By claiming a card or chatting with one, you agree to them.

Who can use Greetmark

You must be at least 16, or older if the law where you live requires it. A card belongs to one person: you, using your own name. Greetmark is invite-only for now: you can claim a card after meeting someone who has one, or when we invite you from the waitlist.

Your card

• You're responsible for what your card says and shows, and for keeping your sign-in email safe.
• Your handle (greetmark.com/you) is yours while you have a card. We may change or take back a handle that misleads people, imitates someone else, or uses another's name or trademark.
• Your card chats with the people you meet using AI. It answers from what you write, and like any AI it can get things wrong. Don't let it make promises for you; check anything important yourself.

Your content

What you put on your card (your photo, words, links, logo and looks) stays yours. You give us permission to store it, show it and copy it as needed to run Greetmark: on your page for the details you make public, to the people who scan your QR for the details you share in person, in the emails your card sends, and to the services that help us run the card (listed under Privacy above). That permission ends when you delete the content or your account, apart from copies that take a short time to clear, as Privacy above explains.

Keep it clean and yours to share: no copyrighted material you don't have the right to use, no profanity, and no adult content.

Using Greetmark fairly

Don't use Greetmark to:

• Spam. Send messages people didn't ask for, collect addresses in bulk, or use invites and card emails to reach strangers.
• Impersonate. Pretend to be another person or a company, or claim a Verified badge or a connection you don't have.
• Scrape. Collect pages, cards or contacts with bots or scripts, or copy Greetmark's content in bulk.
• Harm people. Harass, threaten or deceive anyone, or share anything illegal or hateful.
• Break things. Get into accounts or data that aren't yours, get around our limits, overload the service, or upload anything malicious.

The people you meet

When someone chats with your card, they give you their name, email and what you talked about so you can stay in touch. Use their details for that. Don't sell them, share them for someone else's marketing, or add people to mailing lists they didn't agree to join.

If you chat with someone's card

You don't need an account. Your details go to the person whose card you chatted with, and we handle them as Privacy above describes. Once they're in that person's contacts, how that person uses them is up to them, under these terms.

Price

Greetmark is free for personal use. Plans for professionals and companies will come later. We'll give notice before charging you for anything, and you can delete your account instead.

No warranty

We work hard to keep Greetmark running well, but we provide it as it is and as available, without promises that it will always be up, error-free, or right for your purpose. Card emails can be delayed or filtered as spam, and the chat can make mistakes.

Limits on our liability

To the fullest extent the law allows, we aren't liable for indirect or consequential losses that come from using Greetmark or not being able to, including lost contacts, data, business or profits. To the fullest extent the law allows, our total liability to you for any claim is limited to the lesser of $50 and what you paid us in the 12 months before the claim. Some places don't allow these limits, so they may not all apply to you.

Ending things

• You can stop using Greetmark and delete everything at any time, from Account in your dashboard.
• We may suspend or remove a card that breaks these terms, or that puts other people or the service at risk. Where we can, we'll tell you why first.
• If we ever close Greetmark, we'll give owners at least 30 days' notice and a way to download their contacts.

Changes

If we change these terms, we'll post the new version here with its date, and email owners about anything important before it takes effect. If you keep using Greetmark after that, the new terms apply.
