When we reply
We are a small team in India. Messages are usually answered the same day, and we aim to answer everything within two working days. Anything involving a party happening today gets picked up first — say so in the message and we will see it.
Tell us the phone number you host with and the name of the party, and we can usually find the problem before replying.
An invitation didn't arrive
This is the most common thing people write to us about, and the honest answer is that it is usually not a bug in Nexus Celebrate.
WhatsApp decides whether a given message reaches a given number. An invitation counts as a marketing message in Meta’s classification, and marketing messages sent from a newer business number get throttled per recipient in ways nobody outside Meta can see or predict. The invitation can be correct, sent and accepted, and still not land in one particular person’s chat.
What actually fixes it: every party has a share link on its guest board. Send that yourself — in a one-to-one chat, a family group, over SMS, anywhere. The guest opens the same invitation and can RSVP from it, and nothing about it depends on a template send succeeding. Someone who receives a forwarded link sees the invitation only: never your guest list, never your album.
Worth checking too:
- The number is a valid Indian mobile number with the country code.
- That person has not previously replied STOP to us — if they have, we will not message them again, by design.
- They are looking in their archived or filtered chats.
If invitations are failing for many guests at once, tell us the party name — that pattern we do want to see.
Stop receiving messages
Reply STOP to any message from us. It takes effect immediately and permanently, and it applies to every host on Nexus Celebrate — not only the one who invited you. You do not need an account, and you do not need to explain.
If you would rather just be removed from one host’s guest list, message us from that number and say which party.
Delete my data
Message us from the number you want removed and ask. We will delete your account, the parties you host, their guest lists and their albums. We will ask you to confirm from that number first, because handing someone else’s data to the wrong person is its own problem.
If you were a guest and never signed up, you can still ask — we will remove you from the guest list you were added to.
Albums delete themselves anyway: 60 days after a free party, 365 days after an upgraded one. The full detail is in the privacy policy.
Credits, upgrades and invoices
Credits are bought in a top-up and spent on upgrading a party or generating artwork. There is no subscription and no card kept on file. Your balance and every movement in it are on your account page.
Tax invoices for your top-ups are on the billing page, and you can download them at any time. If an invoice is wrong, or if credits were spent on something that failed on our side, message us — we put those back.
Report misuse
If you received something through Nexus Celebrate that is not a genuine invitation — marketing, a scam, harassment — please tell us, and include the number it came from if you can. We act on these: our terms forbid it and we suspend accounts for it.
Reporting misuse is not the same as replying STOP. Do both if you want the messages to end as well.
Reporting a security issue
If you believe you have found a security weakness, please report it to us privately through the WhatsApp channel above before telling anyone else, and give us a reasonable chance to fix it.
We will not pursue anyone who reports a genuine issue in good faith, does not access or alter other people’s data while investigating, and does not disrupt the service.
