You can check who can see your feedback and who can see your name as the feedback giver by checking the "About the Privacy of your Feedback" section of your review form, or praise/tip screen.
There are two aspects of feedback privacy:
Visibility shows who can see the feedback you have submitted
e.g., Mia and Mia's manager.
Anonymity show's who will be able to see your name as the feedback giver.
e.g., Mia will see your name against the feedback.
Your feedback is visible to the recipient (Impraise Culture) and 2 observers, and your feedback is anonymous.
If you still have questions about your feedback visibility or anonymity, reach out to your HR contact for more information.
