Terms of use

Who we are

Nexus Celebrate is operated by InSynapse Technologies India Pvt Ltd, a company incorporated in India. “We” and “us” mean that company. “You” means whoever is using the service, whether as a host or as a guest.

Your account

Your account is your phone number. There is no password — you sign in with a one-time code sent to that number, so whoever controls the number controls the account. Keep your phone and your WhatsApp secure.

You must be 18 or over to host. The number must be yours — do not sign in with someone else’s. If we learn an account belongs to someone under 18 we will close it.

A guest who was invited does not have an account until they choose to create one. Replying to an invitation does not create one.

Inviting people is a responsibility

This is the section that matters most, and it is not boilerplate. When you add a guest you are telling us you have a genuine reason to contact that person about this celebration. Nexus Celebrate is not a marketing tool, and the business number your invitations are sent from is shared by every host — so one person sending unwanted messages degrades delivery for everybody else.

• Only add people you actually know and are actually inviting.
• Do not upload a purchased, scraped or harvested list of numbers.
• Guest caps are anti-spam guardrails as much as they are a paid tier. Do not try to work around them with multiple accounts.
• If a guest replies STOP, that is final — for every host on the service, not only for you. We will not let you message them again, and asking us to is not something we will do.
• Only use a guest’s details for the celebration you invited them to. Exporting a guest list to contact people about something else is a misuse of the service.

We may suspend or close an account that breaks these rules, without notice where the abuse is ongoing. We would rather lose a host than lose the number everybody’s invitations depend on.

Credits and upgrades

Hosting is free within the free tier’s limits. Beyond them you buy credits, and credits are spent on things that cost us money — upgrading a party, generating artwork, and similar.

• Upgrading a party spends credits from your balance and applies to that party. It is not a subscription and it does not renew.
• Applicable taxes are shown when you top up, and the amount charged is the amount displayed.
• We do not keep your card on file. The payment provider handles card details; we never see them.
• Credits have no cash value and are not transferable or refundable once spent. If something fails on our side and credits are consumed for nothing, tell us and we will put them back.
• Prices and the credit value of a feature can change. A change never applies retroactively to a party you have already upgraded.

Your content stays yours

Photographs, invitation text, artwork you upload, your guest list — all of it remains yours. You give us only the permission we need to actually run the service: to store it, to show it to the people you have allowed to see it, and to put it into the invitations and album you asked us to produce.

We do not use your photographs or your guests’ faces to train anything, and we do not reuse your content to promote Nexus Celebrate unless you specifically agree to it.

Artwork generated for you by the AI tools is yours to use for your celebration. Those tools can produce imperfect or unexpected results, so check what you are about to send before you send it.

You are responsible for having the right to upload what you upload — including photographs of other people, and anything belonging to someone else.

Photographs of children. Celebrations involve children, and your album may contain photographs of them. By uploading one you confirm you have the agreement of that child’s parent or guardian. We never hold a relationship with a child — they have no account with us — so under India’s Digital Personal Data Protection Act that consent sits between you and the parent, and it is yours to have. If a parent asks us to remove a photograph of their child, we will remove it, and we will not require them to justify the request or go through you first. See the privacy policy.

What you may not do

• Use the service to send marketing, political messaging, fundraising appeals or scams.
• Upload anything unlawful, or any sexual content involving minors — we report this.
• Impersonate another person or business.
• Attempt to reach another host’s data, probe the service for weaknesses, or disrupt it.
• Resell the service, or automate it beyond what the product itself offers.

If you find a security weakness, please tell us rather than exploiting it — see the support page. We will not pursue anyone who reports a genuine issue in good faith and gives us a reasonable chance to fix it.

What we don't promise

We cannot guarantee WhatsApp delivers every message. Whether a given message reaches a given number is Meta’s decision, affected by the recipient’s settings and by how our number is rated. It is precisely why every party also gets a share link you can send yourself through any channel. Treat the share link as the reliable path and the WhatsApp send as the convenient one.

The service is provided as it is. We work to keep it available and correct, but we do not promise it will be uninterrupted or error-free, and we are not responsible for a celebration that goes wrong — a guest who did not see their invitation, a reminder that arrived late, an album that was not what someone hoped. Plan anything you cannot afford to have go wrong with a second channel.

To the extent the law allows, our total liability to you for any claim is limited to what you have paid us in the twelve months before it arose. Nothing here limits liability that cannot lawfully be limited.

Ending it

You can stop at any time, and you can ask us to delete your account — see your rights. Deleting your account deletes the parties you host and their albums, so export anything you want to keep first.

We may suspend or close an account that breaks these terms, and we may discontinue the service. If we ever shut it down we will give notice and a window to retrieve your content, except where an account is closed for abuse.

Governing law, and changes to these terms

These terms are governed by the laws of India, and the courts of India have jurisdiction over any dispute.

We may update these terms. The date at the top of this page tells you when they last changed substantively, and we will tell you about a significant change rather than relying on you to notice. Continuing to use the service after a change means you accept it.

Questions about any of this — message us on WhatsApp, or see the support page.
