Terms of Service

Last updated: July 22, 2026

These terms govern your use of Tag Wrangler, a macOS application published by Marshland Software ("we," "us"). By installing or using the app, you agree to them. If you do not agree, do not use the app.

If you obtained Tag Wrangler from the Mac App Store, Apple's Licensed Application End User License Agreement also applies. Where these terms and Apple's agreement differ, the terms more protective of you as the user govern that point.

1. License

We grant you a personal, non-exclusive, non-transferable, revocable license to install and use Tag Wrangler on Apple-branded devices you own or control, for your own use, in line with these terms and any App Store rules that apply. We keep all rights not expressly granted.

2. What you may not do

Copy, sell, rent, sublicense, or redistribute the app except as the App Store terms allow.
Reverse engineer, decompile, or disassemble the app, except to the extent the law expressly permits.
Remove or alter any copyright or attribution notices.
Use the app to infringe anyone's copyright or other rights in music or metadata.

3. Your files and your backups

Tag Wrangler reads your audio files and, when you turn on Editing Mode, writes the metadata tags you change directly into those files, in place. It does not rename, move, or re-encode your audio. Even so, editing tags changes your files, and you are responsible for keeping your own backups. We are not responsible for any loss of or damage to your files, tags, or libraries. Keep a current backup before making bulk edits.

4. Your content

Your music and its metadata are yours. We claim no ownership of them and never receive them. You are responsible for having the right to use and edit the files you load into the app.

5. Optional cloud sync

If you enable preset sync, the app writes your presets and settings to a folder you choose in a third-party service such as Dropbox, Google Drive, or iCloud Drive. Your use of that service is governed by that provider's terms, not ours. Sync is single-user and last-writer-wins, so using the same folder from two places at once can overwrite settings.

6. Third-party software

Tag Wrangler includes open-source components used under their own licenses: TagLib, used under the Mozilla Public License 1.1, and GRDB, used under the MIT License. Those licenses continue to govern those components. Attribution appears in the app's settings.

7. No warranty

The app is provided "as is" and "as available," without warranties of any kind, whether express or implied, including any implied warranties of merchantability, fitness for a particular purpose, and non-infringement. We do not warrant that the app will be uninterrupted, error-free, or that it will meet your requirements. Some jurisdictions do not allow the exclusion of implied warranties, so parts of this section may not apply to you.

8. Limitation of liability

To the fullest extent permitted by law, Marshland Software will not be liable for any indirect, incidental, special, consequential, or punitive damages, or for any loss of data, files, or profits, arising out of or related to your use of the app. Our total liability for any claim relating to the app will not exceed the amount you paid for it. Some jurisdictions do not allow certain limitations, so parts of this section may not apply to you.

9. Updates and availability

We may release updates, change features, or stop offering the app at any time. Updates are delivered through the channel you installed from, such as the Mac App Store.

10. Termination

This license lasts until terminated. It ends automatically if you break these terms. On termination you must stop using the app and remove it. The sections on your content, warranty, liability, and governing law survive termination.

11. Governing law

These terms are governed by the laws of the State of Arizona, United States, without regard to its conflict-of-law rules. This does not remove any consumer-protection rights you have under the law of the place where you live.
