## 1. Information we collect
None.
CroText does not collect, transmit, sell or share personal information. In
particular, it does not collect:
- your name, email address or any other contact information;
- the contents, names or paths of the files you open or edit;
- usage or analytics data, crash reports, or diagnostic information;
- advertising identifiers, device identifiers or any other tracking identifier;
- your location.
Because nothing is collected, there is nothing for us to disclose, retain,
delete or transfer, and no third party receives data from CroText.
## 2. Information stored on your Mac
CroText stores the following locally, so that it can work the way you expect
between launches. None of it leaves your computer.
| What | Why | Where |
| --- | --- | --- |
| Your documents | They are your files; CroText only reads and writes the ones you point it at | Wherever you saved them |
| Recently opened files and folders | To populate File ▸ Recent Files and File ▸ Recent Folders | App preferences |
| Window and tab session state, including text you have not saved yet | To restore your windows and tabs the next time you launch | The app's sandbox container |
| Preferences: theme, font, size, tab width, line numbers, minimap, indentation guides, keyboard shortcuts, interface language and Markdown stylesheet | To remember your settings | App preferences |
| Security-scoped bookmarks for folders you have granted write access to | So a save into a folder you already approved does not ask again | App preferences |
| A workspace index used by Quick Open and project symbols | To make searching a folder fast | Cache inside the app's sandbox container |
You can inspect and revoke the granted folders at any time in
**Settings ▸ Privacy**. Removing the app removes its sandbox container and
preferences along with it; your own documents are untouched.
## 3. File access and the macOS sandbox
CroText runs in the macOS App Sandbox. It has no blanket access to your disk.
It can read and write a file or folder only if you selected it — through Open
File, Open Folder, a save panel, a drag onto a CroText window, or by
double-clicking a document in the Finder.
When a save needs write access to a folder that has not been granted, CroText
asks you once and stores a security-scoped bookmark so it does not have to ask
again. That bookmark is a macOS mechanism that lives on your Mac; it is not a
copy of your files and it is not sent anywhere.
## 4. Network use
CroText makes no network requests of its own. It has no update checker, no
license check and no server to talk to.
The network can be involved in exactly two situations, both started by you:
1. **Opening a link.** Clicking the CroWall link in the About panel, or a link
inside the Markdown preview, hands the URL to your default browser. From
that point on, your browser's privacy policy applies, not ours.
2. **Remote resources in your own documents.** The Markdown preview and the
HTML files CroText compiles are rendered with WebKit. If one of your
documents references a remote image or stylesheet, WebKit fetches it, exactly
as a web browser would. Math and diagrams do not require this: KaTeX and
Mermaid are bundled inside the app and run locally.
The app declares the outgoing-network-connections entitlement solely so that
WebKit can load such resources when your own content asks for them.
## 5. Third-party services and code
CroText contains no advertising SDKs, no analytics SDKs and no third-party
services of any kind.
It bundles two open-source libraries, both executed locally and offline:
- **KaTeX** (MIT License) — typesets mathematics in the Markdown preview.
- **Mermaid** (MIT License) — renders diagrams in the Markdown preview.
Neither library is given your data, and neither contacts a network in CroText.
## 6. Children
CroText is a text editor suitable for all ages. It collects no personal
information from anyone, including children under 13.
## 7. Your rights
Privacy laws such as the GDPR and the CCPA give you rights over personal data a
company holds about you. Since CroText collects no personal data, there is
nothing for us to hold, disclose, correct, export or delete. Any data the app
creates lives on your Mac and is entirely under your control.
## 8. Changes to this policy
If this policy changes, the updated version will be posted at the URL below with
a new effective date. Material changes will also be noted in the app's release
notes.
