Fiche Privacy Policy

Effective date: November 2, 2026

Fiche is a Markdown viewer for macOS developed by Last Cast, LLC. This policy covers the app. The last sections cover email to us and this website.

Data Collection

Fiche does not send your documents, settings, or usage to Last Cast, LLC or to any service we operate.

Fiche does not require an account. Last Cast does not sell or share your data, and Fiche contains no third-party analytics or advertising code.

Fiche reads only the files and folders you choose and never changes them. It remembers each folder you allow until you remove it.

What Fiche Stores on Your Mac

Fiche keeps the following on your Mac, in its own folder:

• Settings, including the window layout and folders you trust for links
• The last session's tabs and scroll positions, and an earlier session kept for 30 days
• Recent files and folders, and when each file was last read
• Folder permissions
• Marks, with the passages they mark and their threads
• Cached web images and temporary rendered pages
• A copy of each document you read (see below)
• The agents Fiche has seen (name, program, and folder) and the MCP token

Fiche also writes some file paths to the macOS system log on your Mac. It does not send them anywhere.

Kept copies. To show what changed, Fiche keeps a copy of each document you read, in its own folder on your Mac, while View > Show Changed Passages is on, which it is by default. A document over 2 MB is not kept. Fiche never sends these copies anywhere, and they are left out of backups. Settings > Privacy shows their size and removes them.

Network Access

Fiche works without an internet connection. It contacts the internet itself only to load web images.

• Web images: Loading an image from the internet contacts the server hosting that image. The server receives the image address, your IP address, that you opened the document, the time, your language preferences, and the app's name and build number with your Mac's system version. The default setting is Only When I Ask. Cached images make no request.
• Links: Opening a web link uses your default web browser, and the site learns that you followed a link from a document. Fiche asks first by default. Mail links open in your mail app without asking.

You choose the documents, image servers, and agents you use. Last Cast does not control them.

Agent Connections

Fiche can let coding agents connect through a local MCP server. Allow agents to connect is off until you turn it on.

What agents can see. A connected agent can see the location of each open file, its outline, your reading position, your selected text, the block you last clicked, your search terms, and marks and threads in any file, open or not. Selected text, clicked blocks, and marks include text from your documents.

What agents can do. Depending on the mode you choose in Settings > MCP, an agent can open and close tabs, search, add marks, and reply on any mark. In Follow mode it can also switch tabs, split the window, and scroll. An agent cannot use Fiche to change your files.

Where that information goes. A connected agent may send what it reads to its own provider, such as an AI service. Last Cast does not control this. Check that provider's privacy policy.

Who can connect. Other applications and web pages on your Mac can connect if they have the server's address, which contains a secret token. Treat the address like a password. It is also saved in the configuration of each agent you set up.

Retention and Deletion

Last Cast holds no data from the app, other than the information Apple passes to us (see Apple and TestFlight), so there is nothing else for us to delete. Everything Fiche keeps stays on your Mac until you remove it.

• Web images are removed from the cache after 30 days without use or when the cache passes 128 MB. Settings > Privacy > Clear Image Cache empties the cache.
• Kept copies of documents are removed 90 days after you last read the document or when they pass 64 MB. Settings > Privacy > Clear Kept Versions removes them.
• Marks and their threads are removed by Edit > Clear Marks in All Files.
• Folder permissions are removed under Settings > Privacy > Folder Access.

To remove everything, delete Fiche and the folder ~/Library/Containers/com.fiche.Fiche. Backups you have made may still hold that folder's other contents, and agents you set up keep the server's address in their own configuration until you remove it.

Withdrawing Permission

You can withdraw any permission at any time:

• Web images: Set Load images from the web to Only When I Ask in Settings > Privacy.
• Kept copies: Turn off View > Show Changed Passages, which also deletes the kept copies.
• Agents: Turn off Allow agents to connect in Settings > MCP. Change Token cuts off every agent that has the current address.
• Folders: Remove them under Settings > Privacy > Folder Access.

Apple and TestFlight

Purchases go through Apple. Apple may give us crash and usage figures from people who chose to share them with developers.

If you test Fiche through TestFlight, Apple passes us your feedback, crash reports, usage information, and device details. Feedback may include your name and email address. See TestFlight & Privacy for what Apple collects and shares.

Email

If you write to us, we hold your address and message. We keep them for as long as we need them to help you, and for no more than one year.

Your Privacy Requests

Readers in the EU and California may ask what we hold about them. We hold no data about you from the app itself. Write to us about any email you sent or any TestFlight feedback you gave.
