Last updated: 2026-09-30
Blues Co., Ltd. ("we") operates "PIT POST (Instagram Posting Assistant)" ("the Service"). This policy explains how we handle user information.
1. The Service
Users send photos, videos and short comments to our LINE Official Account. The Service uses AI to draft captions and, after the user's review or according to the user's settings, publishes the post to the Instagram (and optionally X) account that the user has connected themselves.
2. Information we collect
- LINE user ID / group ID and LINE display name / group name
- Photos, videos and comments sent by the user; AI-generated captions and hashtags
- Connected Instagram account ID, username and access token (stored encrypted); captions of recent posts (to match the writing style)
- Connected X username and access tokens (optional, stored encrypted)
- Settings entered by the user (fixed hashtags, business profile, writing rules)
3. How we use it
- To draft captions and hashtags and to publish posts to Instagram / X on the user's instruction
- To notify the user about drafts and results via LINE
- To troubleshoot, prevent abuse and improve the Service
We do not use the information for advertising and we do not sell it to third parties.
4. Service providers
LY Corporation (LINE Messaging API), Anthropic PBC (Claude API, caption generation), Meta Platforms, Inc. (Instagram API), X Corp. (X API, only if connected), Cloudflare, Inc. (hosting and storage).
5. Retention
Photos and videos are deleted automatically within 7 days. Access tokens are deleted when the user disconnects the Service or requests deletion. Other data is kept only as long as needed to provide the Service and is deleted on request.
6. Security
Access tokens are encrypted at rest and all traffic uses HTTPS. We never ask for or store passwords; logins happen on Instagram's and X's own pages.
7. Disconnecting and data deletion
Removing the Service from Instagram (Settings → Website permissions → Apps and websites) disconnects it and deletes the stored token. For other deletion requests, see the data deletion page.
