how to delete user id from data store roblox

To delete a user’s data from a Roblox DataStore, use RemoveAsync with the exact key that was used to save that user’s data. If you saved data by UserId, the delete call should use that same UserId-based key; if you used a prefix like Player_12345, you must remove that full key.

Basic example

lua

local DataStoreService = game:GetService("DataStoreService")
local ds = DataStoreService:GetDataStore("DataStoreName")

local userId = 4760160964
local key = "Player_" .. userId

local success, err = pcall(function()
	ds:RemoveAsync(key)
end)

if not success then
	warn(err)
end

RemoveAsync(key) deletes that entry, and Roblox forum examples also note that setting a key to nil can remove it in some cases, though RemoveAsync is the clearer option.

What matters most

• Use the same key format you used when saving the data.

• If the data is stored in multiple DataStores, delete it from all of them.

• If your game also stores player info elsewhere, remove it there too, not just in DataStore.

If the key is just the UserId

lua

local ds = game:GetService("DataStoreService"):GetDataStore("DataStoreName")
ds:RemoveAsync("4760160964")

That works only if the data was stored with the UserId as the exact key.

For right-to-erasure requests

Roblox forum guidance says to delete the user’s data from every datastore you use, and to clean up any external databases as well if you have them.

TL;DR: find the exact key format you used, then call RemoveAsync on every DataStore that contains that user’s data.
