Chitose Privacy Policy

Last updated: 2026-11-04

This policy describes data handling in the Chitose Windows desktop application, distinguishing the directly downloaded test version from the Steam distribution channel. It does not cover the Solunastre website or replace the policies of Steam, Microsoft, cloud services or AI providers.

Chitose uses local files and records. You do not need a Solunastre account. Writing notes, using focus timers, and tracking growth do not send that content to us. The sections below explain how data is sent when you use AI or load online content.

1. Provider and contact

Chitose is provided by Solunastre. Questions about this policy can be sent to solunastre@gmail.com.

2. Where your data is stored

Library: Notes are ordinary Markdown files (.md and .mdx) in your chosen folder. The .chitose folder holds version history, trash, archives, exports and images in the default location.
Application data: Settings, focus and task records, growth records, imported videos and music, embed lists, the search index, AI settings, conversations and memory are stored in Chitose’s folder on your computer. The release version normally uses the com.aira.chitose folder under Windows %APPDATA%.
Interface and web cache: WebView2 keeps separate local settings and cache, normally in the com.aira.chitose folder under %LOCALAPPDATA%.

Putting a library in a cloud folder does not automatically sync all of this local data. Your chosen sync service processes the files placed in its synced folders.

3. What the studio receives

The studio does not provide note hosting or membership accounts. You do not need to upload your notes, focus records, or growth records to the studio to use these features.

If you email us, we receive the message and attachments you send. You choose what to share.

4. When network connections occur

Steam: Purchases, downloads, updates, refunds and platform usage records for the Steam channel are handled by Steam under Valve’s policies. Chitose does not process platform payments or refunds.
Directly downloaded test version: The application checks GitHub in the background, downloads updates and verifies signatures. GitHub receives ordinary connection information such as your IP address. This update process does not send your notes or focus records.
WebView2: Chitose uses this Microsoft component to display its interface. Component installation, diagnostics and crash information are governed by Microsoft’s and Windows’ relevant settings and policies. Chitose does not handle that data on their behalf. Installing a missing component may require internet access.
Online content: Loading chosen or previously saved video or music embeds, remote images or HTML files that make network requests connects to the content provider. It may receive information such as your IP address, use cookies or keep records under its own policy. Embedding and sign-in also depend on that service.
External links and cloud sync: Links open in your browser. Cloud sync services you choose process files in their synced folders, potentially including notes and data inside .chitose.
AI conversations: Data flows for this optional feature are described next.

Local notes and focus tools work offline. Updates, AI, and the online content listed above connect to the internet when used.

5. Optional AI conversations

AI is off by default. Before enabling it, Chitose explains that content will be sent to the selected provider. Install and sign in to the Claude Code or Codex command-line tool yourself. That tool manages sign-in and authentication; Chitose’s settings do not ask you to enter an AI account password or key.

Content that may be sent includes messages you type, character settings and memory summaries, and—depending on the room and tool permissions—library, folder and document names and locations, plus file content the tool reads to answer. The command-line tool sends this to Anthropic or OpenAI. These conversations do not pass through a server run by the studio. Creating conversation summaries and long-term memory also uses the same tool and service.

File access differs by context: The Study assistant may read or modify files according to your requests and the tool’s permissions. In the Parlour, Claude Code runs in a conversation-only mode without note-reading or writing tools. Codex may still use file access tools. Whether a Parlour conversation can access notes therefore depends on the tool you use.

Local records and deletion: Chitose stores conversations, summaries and memory locally. Turning AI off in settings stops Chitose from starting new AI conversations. You can also clear conversations or long-term memory saved by Chitose. This does not also delete records retained by the command-line tool or provider; those follow their own settings and policies.

6. Moving to another computer

Move your library separately from application data. You can copy the library and use Chitose’s .chitose-data export/import feature for focus, tasks, growth and preferences.

The export excludes notes themselves, library path lists, imported videos and music, AI settings, conversations and memory. Import replaces the corresponding existing data on the destination computer and makes a backup first. The export contains personal records; keep it in a place you choose and control.

7. Deleting data

You can delete your notes and library using your file manager. History, trash, archives and default images are in .chitose; check what you want to keep before deleting it.

After closing Chitose, you can delete application data and cache from the local folders listed above. AI conversations and memory can also be cleared in settings. Manage records held by the command-line tool, Steam, cloud services or other providers separately through those services.

8. Policy updates
