Privacy Policy

We collect the following information through the Service.

• Messages, text, and photos you send us via LINE or WhatsApp.
• Store profile information you configure (store name, preferred caption language, messaging language, etc.).
• When you connect an Instagram professional account, we obtain basic account information (Instagram user ID, username, profile picture) and an access token that lets our system publish content to that account on your behalf.
• Payment-related information once billing is introduced (card details themselves are held by our payment processor, Stripe, not by us).
• Usage logs such as number of uses and timestamps.

• Generating an Instagram caption from the photo and any note you send us.
• Publishing the photo and generated caption to your connected Instagram account, but only when you explicitly instruct us to (by replying "post"/"投稿する" in the chat). We never publish anything to your Instagram account without this explicit action from you.
• Providing, operating, and billing for the Service.
• Preventing abuse and managing usage limits.
• Improving the Service and responding to inquiries.

When you connect your Instagram professional (Business/Creator) account through "Instagram API with Instagram Login", we request the following permissions, and only use them for the purposes below:

• instagram_business_basic — to read your connected account's basic profile information (username, account ID, profile picture), used solely to confirm the connection and show its status on your store settings page.
• instagram_business_content_publish — to publish, on your explicit request only, the photo you sent us together with the AI-generated caption to your connected Instagram account. We do not use this permission for any other purpose, and we never post automatically without your instruction.

The Service integrates with the following external services. How each service handles data is governed by its own privacy policy.

• LINE Corporation — for sending and receiving chat messages via the LINE Messaging API.
• Meta Platforms, Inc. — for sending and receiving chat messages via the WhatsApp Cloud API, and for Instagram account connection and content publishing via the Instagram API.
• Google LLC (Gemini API) — the photo you send and any accompanying note are sent to generate the caption text.
• ImageKit — for hosting and processing the photos you send.
• Stripe, Inc. — for payment processing once billing is introduced.

Other than as described above, we do not share personal information with third parties without consent, except as required by law.

We retain information for as long as necessary to provide the Service, or as required by law. After cancellation or disconnecting your Instagram account, we delete the related information within a reasonable period, except where retention is legally required.

You can disconnect your Instagram account at any time from your store settings page, which revokes our access token immediately. For full deletion of your data, see our Data Deletion Instructions.
