If it needs to be super-secure, as you say, you should use User Read-Only Data for this, and update the value in Cloud Script. After all, if you give the client the authority to write the data, cheating it becomes trivial for a technically-minded person. Because of that, part of the solution is necessarily JavaScript, since that's the language you'll use for the Cloud Script. The default script is automatically added to all new titles, so when you click on the Servers tab, you'll see a good example of how to use Cloud Script. The call you'll want to make there to write the data is server.UpdateUserReadOnlyData. The docs for it are here: https://api.playfab.com/Documentation/Server/method/UpdateUserReadOnlyData. But the key thing to know is that you'll be writing a key/value pair out in the data, and you need to specify the PlayFabId of the player, as shown in the Cloud Script example. If you set the Permission to Public, you'll enable other users to also be able to read that data, if you need that as well.

On the client, you'll read the data using https://api.playfab.com/Documentation/Client/method/GetUserReadOnlyData. The call will look something like this:

GetUserDataRequest request = new GetUserDataRequest();

request.Keys = new List<string>();

request.Keys.Add(buttonState);

PlayFabClientAPI.GetUserReadOnlyData(request, OnGetButtonStateLoaded, OnGetButtonStateError);

Where buttonState is the name of the key you use to store this data. Of course, you could just leave the Keys parameter out entirely, and get back the full list of all User Read-Only Data for the user.

Then, your OnGetButtonStateLoaded would look something like this:

void OnGetButtonStateLoaded(GetUserDataResult result) {

    UserDataRecord dataRecord;

    result.Data.TryGetValue(buttonState,out dataRecord);

    if (dataRecord != null) {

        // do some logic associated with whether the value is 0 or 1

    }

}
