This extension does not automatically collect personal information. It receives an email address and optional name only when a user enters them and submits the contact form.

• OAuth access / refresh tokens (for Raindrop.io authentication)
• Currently selected collection
• Theme preference (auto / light / dark)
• Link open mode preference
• Bookmark list local cache (TTL 5 minutes)
• Kagayoi Support contact session in window.localStorage (email address, support access token, and expiration)

These values are stored locally. OAuth tokens and bookmark or collection data are used only for Raindrop.io authentication and API communication. Only bookmark domain names are sent to Google Favicon Service as described below. The contact session persists across browser restarts for checking replies and is removed when it expires or Kagayoi Support rejects it. Logging out of Raindrop.io does not remove this separate support session.


Data is not sold or used or shared for advertising, analytics, or creditworthiness. Google Favicon Service receives bookmark domain names for favicon retrieval. Contact submissions are received only by Kagayoi Support and used only to respond to the inquiry.

• raindrop.io — OAuth authentication
• api.raindrop.io — bookmark retrieval
• www.google.com — only the domain name is sent for favicon retrieval
• fonts.googleapis.com / fonts.gstatic.com — popup UI fonts (no user data sent)
• support.kagayoi.com — contacted only when the user submits the contact form

Only when the user submits the contact form, the extension sends the entered email address, optional name, inquiry category, subject, message, product ID, extension version, and locale to Kagayoi Support. It does not send bookmarks, collection data, or Raindrop.io authentication tokens.

• identity: Raindrop.io OAuth flow
• storage: local storage of settings and cache
• alarms: refresh the selected collection's bookmark cache every five minutes
• host_permissions (api.raindrop.io, raindrop.io): API communication
• host_permissions (support.kagayoi.com): email verification, contact submission, and retrieving the submission result after the user submits the form
