Developer Policy clarification

[-cje7yf_f8mmm]

Hi everyone,
I’m developing a free, non-monetized iOS project and would like to clarify some Developer Policy requirements before public release.
Could a Spotify staff member or moderator advise whether this board is the appropriate place to ask about the following scenarios, or direct me to an official private channel?
- Section III.5. Music-service selection: Supporting more than one music provider while each user plays tracks exclusively through their chosen provider’s official APIs/SDKs. A shared track reference may originate from one provider and be resolved to an equivalent track on the listener’s selected service. Audio is not downloaded, rehosted or mixed.
- Section III.2. Preference polls: Asking users which of two tracks they prefer, without prizes or any form of rewards.
- Section III.13. Listening-data comparisons: Whether comparing consenting users’ listening activity is permitted, and whether comparing only tracks they explicitly choose to share would be treated differently.
- Disconnection and deletion: How the deletion requirements apply to user-created posts containing Spotify-derived track references and related comments or reactions from other users.
My purpose is to understand the requirements and adjust the implementation accordingly. I’m keeping project-specific details out of this public post, but can provide relevant information through an official private channel if needed.
Pointers to existing official explanations would also be appreciated.
Thank you.
