It's worst !
Equation are filled with Token information
Default value are filles with Token information

It's NOT related to welcome page : value are set everywhere !

Sorry Denis,
i took the .lsa you posted, disabled the welcome page and submitted the survey. In "Answers" the fields are all blank in my submission.
So the welcome page "switches" something?

I think this was never different and was discussed in the past.
Anonymized means our system does not write the token information and does not write timestamps in the response , so both participant and response cannot be connected.

It does not mean that the survey admin cannot show token information inside the survey.
If the admin wants to cheat by saving that token information into an expression, well, what can you do?

Hello c_schmitz, thanks for your reply.
As long it is clear for us how to set up the survey it is all good.
I mean on one side we just get data from the participants' table (fast and easy) on the other side we have to send data via parameters in the invitation URL.

So, my 2 questions are: which way does LS think is the right one to pursue in an anonymized survey? Why does the behaviour change activating/deactivating the Welcome page?

Thanks!

It does not mean that the survey admin cannot show token information inside the survey.

@c_schmitz : it's like that since years now. Since it work like that : updating behaviour is an issue.

Have a new feature :
Survey anonymous : complete (current)/partial (allow usage of token information)/No
Seems the best solution here.

Else : we need to update anonymous for public survey

The record of your survey responses does not contain any identifying information about you, unless a specific survey question explicitly asked for it.

Is not true since you can add {TOKEN} for equation.

@c_schmitz : look at the discussion here : we need a real technical solution for anonymous survey with token. Where the hosting company (LimeSurvey GMBH) can confirm that it is impossible to link responses to invitations.
