Privacy policy

Effective August 27, 2026. Last updated August 27, 2026.

This page explains what information 123RSVP collects, why we collect it, and which companies help us run the service. In this page, 123RSVP, we and us all mean the service you are reading about.

Awaiting counsel. This document describes what 123RSVP actually does today and is written to be relied on, but a lawyer has not completed a review of it. One item is deliberately absent rather than drafted here: a minimum-age representation.

Information we collect

Why we collect it

123RSVP shows no advertising and runs no analytics or advertising services, so none of this information is used to build an advertising profile.

Text messages

If you sign in by phone, we send you a one-time authentication code by text message. We send you a code only after you ask for one. Loading the sign-in page sends nothing.

Your mobile number, SMS consent, and opt-in data are not sold or shared with third parties or affiliates for marketing or promotional purposes. We disclose mobile information only to service providers as needed to operate phone authentication and deliver a text message you requested, including our hosting, database, messaging provider, and participating carriers.

Carriers are not liable for delayed or undelivered messages.

Who else processes your information

We use a small number of service providers to run 123RSVP. Each one receives only what it needs for its part of the service, and each one is permitted to use what it receives only to provide the service we have contracted it for. None of them is permitted to use your information for their own marketing, and we do not sell your information to any of them.

No analytics service and no third-party error tracking service is connected to 123RSVP.

How long we keep information

Apart from the ten minute expiry above, we do not promise an automatic deletion schedule.

Your choices and your requests

How we protect it

We store one-time codes only as keyed digests, we limit how often a code can be requested and how many times it can be tried, and we do not log phone numbers, codes or session cookies. No service can promise perfect security, and we do not.

Changes to this page

If this page changes, we will update the effective date at the top. This page describes how 123RSVP works today.
