Connected and hosted services

Operating-system frameworks are supplied by their platform vendors and are not bundled open-source libraries. Connected social networks, payment processors, security providers, email-delivery services, AI providers, media services, and URL-shortening services are integrations or hosted services rather than software redistributed by PostChorus.

These services may include Bluesky, Mastodon, LinkedIn, Threads, Tumblr, Pinterest, Nostr, X, Google Gemini, GIPHY, Cloudflare, Stripe, Apple, ZeptoMail, YOURLS installations operated by customers or their providers, and other services selected or connected by a customer.

The availability and use of a connected service may be governed by that provider’s own terms, privacy policy, developer agreement, acceptable-use requirements, and authorization rules.

Reference to a third-party product or service describes an integration, compatibility relationship, or service used to operate PostChorus. It does not imply sponsorship, endorsement, ownership, or affiliation unless expressly stated.
