Is SponsorBlock for Spotify - Skip Sponsorships safe?

Low risk

SponsorBlock for Spotify sends Spotify playback skip telemetry to sponsor.ajay.app, including in private windows by default.

When it runs on open.spotify.com, the extension contacts sponsor.ajay.app to retrieve skip segments for the current Spotify track or episode. When a segment is skipped, it reports the segment UUID and current Spotify media ID to the same server, and its default settings allow this view-count telemetry in private browsing.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

Shared hosts - 1 hostname

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
