Privacy Policy
Last updated: July 9, 2026
foldermap.app ("we", "the site") is a browser-based tool that visualizes the structure of ZIP archives. This policy explains what data we handle and how.
1. Data you upload
Files you drop into foldermap.app are parsed entirely in your browser using JavaScript. Your ZIP files, their contents, and the derived folder trees are never uploaded to our servers. Nothing leaves your device.
2. Local storage
We may store small preferences (such as UI settings or an unlock flag) in your browser's localStorage. You can clear this at any time from your browser settings.
3. Analytics
We may use privacy-respecting analytics to understand aggregate usage (page views, device type, referrer). We do not sell personal data.
4. Advertising
This site may display advertisements served by third-party ad networks, including Google AdSense. These providers may use cookies and similar technologies to serve ads based on your prior visits to this and other websites. You can opt out of personalized advertising by visiting Google Ads Settings or aboutads.info.
5. Cookies
Cookies may be set by embedded third-party services (analytics, ads). You can disable cookies in your browser; the core foldermap.app functionality will still work.
6. Children
foldermap.app is not directed at children under 13 and does not knowingly collect data from them.
7. Changes
We may update this policy. The "Last updated" date at the top reflects the latest revision.
