Privacy policy
Last updated November 7, 2026
9arty is an app for sending party invites and collecting RSVPs. This page says what it collects, who can see it, and how to have it removed. We don't sell your information, show ads, or use analytics or advertising trackers.
If you host a party
Hosts sign in with Google, Microsoft, GitHub or Discord. We keep:
- Your name, email address and profile picture link, as that service provides them.
- The sign-in details that service issues to us for your account. We never see your password.
- What you put on your invites: titles, dates, places, descriptions, images, questions and announcements.
If you answer an invite
Guests don't need an account. We keep what you give us:
- Your name, your answer, how many people you're bringing, and any questions the host asked.
- Your email address, if you choose to give one.
- What you add to the party: comments, reactions, date votes and what you offer to bring.
Who can see it
- The host and any co-hosts see everything guests give on their event, including email addresses and answers, and can export the guest list.
- Other people with the invite link may see your name and what you post on that invite, depending on the host's settings.
- Invites a host marks as public can be listed on the Explore page.
We won't send you party messages until you confirm your address using the link in a single confirmation email. Every message after that has a link to stop emails about that party. We use email only for the party it concerns, and never for marketing.
What your browser stores
- A cookie that keeps hosts signed in.
- Your light, dark or party colour choice.
- A private token that lets you change your RSVP or date vote on that device.
Security records
To limit abuse we count requests using a scrambled version of your IP address or email address, and those counts expire. We keep a log of actions such as creating an event or posting a comment. It records which account or event was involved, and doesn't record addresses. Our web server may also keep standard request logs, which include IP addresses.
Services we rely on
- Hostinger runs the server and database.
- Cloudflare handles our domain, stores invite images and forwards mail to our contact address.
- Google, Microsoft, GitHub and Discord handle sign-in if you choose them.
- Resend delivers email, once email is switched on.
Keeping and removing your information
We keep your information until it's removed. It isn't deleted automatically after a party. Guests can cancel an RSVP using their private RSVP link, and hosts can delete their drafts. To remove an account, a published event or anything else, or to ask for a copy of what we hold about you, email privacy@9arty.app.
Children
9arty isn't meant for children under 13, and we don't knowingly collect their information.
Changes and contact
If this policy changes, we'll update this page and the date at the top. Questions go to privacy@9arty.app.
