How long should a host keep guest addresses and dietary notes after the event has ended?

You collected more than you think you did

Run through a finished RSVP list and take stock of what is actually sitting in it. Full legal names, home mailing addresses, personal email addresses, mobile numbers, the names of children, the names of partners who were not on the original invitation, and free text notes about allergies, intolerances, pregnancy, mobility needs, and religious observance. Individually these feel harmless. Together they are a tidy dossier on a few hundred people who gave you the information for one evening, not indefinitely.

The dietary and accessibility fields deserve particular attention because they edge into health information. A guest writing that they carry an epinephrine auto injector, or that they need a step free route to the ceremony, is telling you something they would probably not post publicly. They shared it so the caterer could plate correctly and the venue could open the right door. Once those two things have happened, the note has done its job, and keeping it forever creates a small risk with no matching benefit for anyone.

Keep the short list, delete the rest

There is a genuinely useful residue from any event, and it is short. Names and mailing addresses are worth keeping for thank you notes and for the next event, since re-collecting addresses is the single most tedious part of starting over. A simple attendance record is worth keeping too, because knowing who came and who declined helps you size the next guest list and spot the friends you have not seen in years. That is roughly it.

Everything else can go once the event is over. Allergy and dietary free text, accessibility requests, phone numbers gathered only for day of logistics, and any notes you or a helper typed while chasing replies should be deleted rather than archived. The practical move is to export a clean list of names and addresses, save that one file where you actually keep things, and then delete the full export, the working spreadsheet, and the responses in the tool itself. Doing it in one sitting takes minutes; doing it never is the usual outcome.

Remember who else is holding a copy

Your RSVP tool is rarely the only place this data lives. By the day of the event, a version of the guest list has usually reached the caterer, the venue coordinator, the planner, a parent who wanted to check spelling, and a group chat where someone pasted a screenshot. Every email attachment is a copy, every shared cloud link is a copy, and the printed seating chart and place cards at the venue are copies that end the night in a bin or in the back of somebody's car.

Cleaning up your own account while five other copies float around accomplishes very little, so make a short list of everyone who received the file and ask them to delete it once their part is finished. Most vendors will do this without complaint, and a professional caterer or planner will already have a policy. Collect the paper at the end of the night as well, since dietary indicators on place cards and kitchen sheets are exactly the sort of thing nobody thinks of as data. If your event was run by a business rather than a household, ask your own counsel about what your state expects, because privacy rules for organizations vary and this is not legal advice.

A retention plan you can run in under an hour

Put three dates in your calendar the week the invitations go out. The first is a few days after the event: export names and mailing addresses to a single file and store it somewhere you will find it again. The second is roughly thirty days out: close the RSVP form so nothing new arrives, revoke shared links, and delete the dietary, accessibility, and phone number fields from your working copy. The third is sixty days out: delete the responses in the tool and the working spreadsheet itself, along with the copies hiding in your sent mail and downloads folder.

It also helps to say what you are doing on the form itself. One plain sentence near the dietary question, telling guests the information goes to the caterer and is deleted after the event, raises reply quality more than most hosts expect. People who have been vague about an allergy tend to be specific when they understand who reads it and how long it lives. Good privacy practice here is not just a duty. It gets you better data at the exact moment you need it to be accurate. Related: How do you give your caterer an accurate final headcount without recounting guests all week?
