Atelier Pin offers an optional social-publishing integration that lets you publish generated content to your own accounts on Pinterest, Instagram, Instagram Stories, Facebook, Facebook Stories, TikTok, Bluesky, and similar platforms. This integration is brokered through Zernio (operated by ARBICHAT, S.L., Carrer Mallorca 2A, 17230 Palamós, Girona, Spain — Tax ID CIF B75253252). It is fully opt-in per platform: it is only active for the platforms you have explicitly connected under Settings → Connected accounts.
11.1 What we ask each platform for. When you connect a platform, Zernio (on our behalf) requests only the OAuth scopes strictly necessary to perform the publishing actions you have asked for. For Pinterest these typically include boards:read, pins:read, pins:write and user_accounts:read; for Meta platforms the equivalent pages, instagram_content_publish and business_management scopes; for TikTok the video.publish / video.upload scopes; for Bluesky the credentials you provide for the app-password flow. The exact list of scopes is shown to you by the destination platform at the moment you authorise the connection.
11.2 Where OAuth tokens are stored. Access and refresh tokens issued by destination platforms are stored by Zernio under Zernio's own security controls, not by Atelier Pin. Atelier Pin holds only the connection metadata listed in Article 2.5. Tokens are automatically purged by Zernio after repeated refresh failures.
11.3 How we use connected-account data. Connected-account data is used exclusively to operate the publishing feature you have asked for. We do not sell, rent, or share it with unrelated third parties. We do not use it for advertising profiling. We do not analyse the content of pins or posts already on your account beyond what is strictly necessary to publish what you have prepared in Atelier Pin.
11.4 Publishing is always under your control. No post is ever published without your explicit action. Every scheduled item remains visible, editable, and cancellable in your Schedule view until the scheduled time, and is published only at that exact time or when you press Publish now.
11.5 Disconnecting and revocation. You can disconnect any platform at any time from Settings → Connected accounts. On disconnect, we instruct Zernio to revoke the access tokens immediately and we delete the connection metadata we held for you within 24 hours. You can also revoke Atelier Pin's / Zernio's access directly from the destination platform's own account settings at any time.
11.6 Zernio's own legal terms. By connecting a platform through Atelier Pin you also accept Zernio's Privacy Policy, Terms of Service, and Legal Disclosure. Zernio is established in the European Union (Spain).
