Hello @andra.enache , 

Within the Review cycle in Personio, it would not be possible to make a Feedback not visible to the Supervisor. As you can see from my screenshot, the option will always be greyed out.

Also, by default any Feedback/Reviews  will show who submitted them and so it would not be possible to send anonymous Feedback.

I would like to encourage you to post this suggestion of improvement in our ideation area. This way, other users will be able to vote for it, and the suggestion will be shared with our product team.
In order for us to fully understand your idea, I share with you a couple of questions that your description should clarify when posting in the ideation area:

• What would you like to achieve with Personio? What issue do you need to solve?
• Why? What would be the added value for you?
• How are you solving it right now?

The more details, the better! However, remember not to share any personal or business data with the public.
Make sure to add the link to the idea in this thread, so that other users that find your question can upvote it.
Thank you in advance for sharing your ideas with us .

Best,

Anna Lisa
