## 💻 System Requirements

### Windows
- Minimum: Windows 10 version 22H2 (build 19045) or newer, fully updated. Older Windows 10 builds (2004/20H2/21H1/21H2) are end-of-life and may fail to start with a .NET runtime error (`0x80131506`).

### macOS

- **Minimum macOS version**: 12 (Monterey) or newer
- **Recommended**: macOS 14 (Sonoma) or newer - the oldest macOS that .NET 10 is supported on. Subtitle Edit still starts on 12 and 13, but that combination is not one the .NET runtime is tested against.
- The `.dmg` is self-contained: `libmpv` and `ffmpeg` are bundled inside `Subtitle Edit.app`, so no MacPorts or Homebrew install is required.

#### Installing Subtitle Edit on macOS

As of **v5.2.0**, the `.dmg` is signed with an Apple Developer ID and notarized by Apple, so it opens normally — no Terminal quarantine-removal step is needed:

1. **Download** and **double-click** the `.dmg` file to mount it.
2. In the window that appears, **drag `Subtitle Edit.app` into your `Applications` folder**.
3. Open **Subtitle Edit** from Applications (or Launchpad).

### Linux

#### Flatpak (any distribution)

A Flatpak package is available from the [Releases](https://github.com/SubtitleEdit/subtitleedit/releases) page. It bundles all required dependencies (mpv, ffmpeg) — no separate installation needed.

```bash
flatpak install SubtitleEdit-linux-x64.flatpak
flatpak run dk.nikse.subtitleedit
```

#### Native builds (`.tar.gz`)

Requires mpv and ffmpeg (ffmpeg is normally already installed) to enable video functionality.

##### Debian/Ubuntu
```bash
sudo apt update && sudo apt install -y mpv libmpv-dev ffmpeg
```

##### Arch
```bash
sudo pacman -S mpv ffmpeg
```

##### Fedora
```bash
sudo dnf install mpv-libs ffmpeg-free
```
(or `ffmpeg` from [RPM Fusion](https://rpmfusion.org/))

##### openSUSE
```bash
sudo zypper install mpv ffmpeg
```

> ⚙️ Note: The provided builds are self-contained and do not require a separate .NET installation.

## 🔒 Privacy

**Subtitle Edit** is an offline, open-source application.  
It does **not** collect, store, transmit, or analyze the content of your subtitle files, media files, or any associated metadata — not for analytics, not for model training, and not for any other secondary purpose, now or in the future.

All core features, including editing, converting, video playback, and **local auto-backup**, run entirely on your device.

If you choose to use optional third-party online services within Subtitle Edit (such as translation, speech-to-text, text-to-speech, OCR, or dictionary/lookups), only the minimal data required to perform that specific request is sent directly to the selected provider. Any such data transfer is governed by the provider’s own privacy policy, and Subtitle Edit does not retain or forward this data in any way.

Subtitle Edit aims to give you full control over your files — your data stays yours.
