Privacy Policy

Last updated: 24 July 2026

In short: NYCTAVIS is a local-first Windows application. It runs entirely on your computer. It does not send your files, scan results or usage anywhere. There is no cloud, no telemetry, and no account.

1. Who we are

NYCTAVIS ("the app", "we") is a desktop utility for Windows that helps you find junk, duplicate files and reclaimable disk space, and clean only what you approve. This policy explains how the app handles information.

2. Data we collect

We do not collect any personal data. NYCTAVIS has no analytics, no advertising, no tracking, and does not create user accounts. We do not receive your files, file names, folder paths, scan results or system information — none of it is transmitted to us or to any third party.

3. Data processed locally on your device

To do its job, the app reads your disk and stores its working data only on your computer, under your user profile (for example %LOCALAPPDATA%\LocalSystemAuditor). This includes:

Scan results and recommendations (a local database);
The quarantine (items you chose to isolate) and the action history;
Your preferences (such as the interface language).

This data never leaves your device. You can remove it at any time by uninstalling the app or deleting the folder above.

4. No cloud, no telemetry, no network

NYCTAVIS performs its analysis and cleanup offline. It does not upload your data and does not require an internet connection to scan or clean.

5. Cleaning and deletion

The app never deletes anything without your explicit confirmation. Items you clean are first moved to a reversible local quarantine so you can restore them. Permanent deletion is an action you choose and confirm.

6. Purchases

If you buy the optional Pro upgrade, the purchase is handled by the Microsoft Store under Microsoft's own terms and privacy policy. NYCTAVIS only checks whether a valid license is present on your device; it does not process or store your payment information.

7. Third-party components

The app is built with third-party open-source components (such as the Qt/PySide framework and psutil). Their license notices are included with the application. These components run locally and do not send your data anywhere.

8. Children

NYCTAVIS is a general-purpose utility and is not directed at children. Since it collects no personal data, it does not knowingly process any data from children.

9. Changes to this policy

If this policy changes, the updated version will be posted on this page with a new date.
