All shipped licences are F-Droid-compatible (permissive, or GPL-2.0/MIT dual where
the MIT clause is elected).

## Build-time only (not shipped in the APK)

| Component | Purpose | Licence |

| Go toolchain 1.24.3 | compiles `libwg-go.so` | BSD-3-Clause |
| `termux-elf-cleaner` (`tunnel/tools/elf-cleaner`) | strips ELF debug sections from `libwg.so`/`libwg-quick.so` at build time | GPL-3.0-only |

`termux-elf-cleaner` runs only during the build on the build host; it is not
distributed with the application.

## Note on the wireguard-go history

Historically `wireguard-go` was licensed GPL-2.0. The current upstream Go module
(`golang.zx2c4.com/wireguard`), which this project builds, is licensed MIT, and
every source file in the pinned module revision is marked `SPDX-License-Identifier: MIT`.
