Privacy policy.

Last updated 10 November 2026. LunaZip is a free file archiver for Windows and Mac made by WolfByte.Works ("we", "us") in Texas, USA. This policy covers the LunaZip app and this website, luna.wolfbyte.works.

The short version

• Your files never leave your computer. We never receive your archives, your files or their names.
• The app has no account, no ads and no analytics. It only goes online to check for updates, or when you ask it to fetch a file from the web.
• The website uses analytics and advertising cookies only if you say yes. Read the cookie policy.
• We don't sell your personal information.

The app

• LunaZip opens, creates, checks and repairs archives on your computer. Your files and archives are never uploaded anywhere.
• There's no account, no sign-in and no license key.
• Saved archive passwords stay on your computer, encrypted by Windows for your user account, or in your Keychain on a Mac. You can also have LunaZip ask for Windows Hello or Touch ID before it uses them. We never see them.
• The safety check before extracting runs on your computer. On Windows, the optional virus scan uses Microsoft Defender on your own computer; Microsoft's privacy terms apply to Defender.
• Settings, recent archives, the activity list, the archive search index, scheduled backups and the error log (errors.log) are stored in LunaZip's folders on your computer. Nothing in them is sent to us.
• If you make RAR files, LunaZip runs your own installed copy of WinRAR (Windows) or RARLAB's rar (Mac) on your computer.

When the app goes online

• Update checks. LunaZip downloads our update list from luna.wolfbyte.works and, when you choose to update, the new installer or disk image. As with any web request, our host Cloudflare sees your IP address and the app's request details. We don't use them to identify you.
• Peek at a Web Zip. If you use this tool, LunaZip downloads the parts of that zip it needs from the address you gave it. That website sees your IP address, as with any download.

This website

• The site is served by Cloudflare, which processes standard request data such as your IP address, browser and the page asked for, to deliver pages and protect the site from abuse.
• Analytics, only with your consent: Google Analytics and Cloudflare Web Analytics count visits and pages so we can improve the site.
• Advertising, only with your consent: Google Ads, Microsoft Advertising and Meta measure whether our ads work and may show you LunaZip or other WolfByte.Works ads elsewhere.
• Until you choose, and if you say no, none of these load. You can change your choice any time with "Your privacy choices" at the bottom of every page. The full list is in the cookie policy.
• If your browser sends Global Privacy Control, we treat it as an opt-out of sale and sharing, and advertising stays off.

Why we may use it

We deliver and protect the website because we have a legitimate interest in running it securely. We use analytics and advertising only with your consent, which you can withdraw at any time.

How long we keep it

We don't hold any data about how you use the app. Google Analytics keeps website analytics data for no longer than its retention setting, at most 14 months. Cloudflare keeps request logs for its own short security and operations periods.

Your rights

Depending on where you live (for example the EU, the UK or US states such as California and Texas), you can ask to see, correct or delete personal information we hold about you, object to or limit its use, or opt out of targeted advertising. Because the app collects nothing and the website keeps only what the tools above collect, there's usually very little to find, but we'll answer every request. Email [email protected]. You can also complain to your local data protection authority.

Children

LunaZip isn't directed at children under 13, and we don't knowingly collect their personal information.

Changes

If this policy changes, we'll update it here and change the date at the top.
