Privacy Policy

Nexus Asset Vault · Effective 26 October 2026

Polygons Arts ("we") makes Nexus Asset Vault ("the app"). This policy explains what information the app and our servers handle, why, and what you can do about it. In short: your files never leave your computer, and we collect only what is needed to run accounts and licenses.

1. Using the app without an account

The free version works without an account and does not send us your files, file names or usage. Two things do reach the internet:

• Update check. Each time the launcher starts it asks our server whether a newer version exists. Like any web request, this reveals your IP address and the app version.
• Website icons. When you save a web link in the app, its small icon is fetched from Google's favicon service, which receives the link's domain name.

2. With an account

When you sign in to use a paid plan, our server stores:

• Your email address and a hash of your password (we never store the password itself).
• A device identifier — a one-way hash computed from your computer's hardware — and the computer's name. It lets an account be active on one computer at a time.
• The IP address and time of the last sign-in or license renewal from each device.
• Your plan and the licenses issued (version, date, expiry).
• Fingerprints (hashes) of the app's own program files, sent with sign-ins and renewals, to detect modified copies. These are the app's files, not yours.

3. Problem reports

If you send a report from the app — or agree to send one after an error — we receive your message, an optional contact address and, unless you untick it, technical details: app version and build, plan, operating system, the error and the app's recent log. The log can contain names of files or folders the app was working with. We use reports only to fix problems and answer you.

4. AI features

AI tools use your own API key with the provider you choose (for example OpenAI, Anthropic, Google or Alibaba Cloud). Requests go directly from your computer to that provider; we do not see them. The provider's own privacy policy applies.

5. What we do not do

• We do not upload, scan or look at your files or libraries.
• We do not sell or rent personal information.
• We do not use advertising, tracking cookies or analytics in the app or on this website.

6. Why we use this information

To create and secure your account, issue and renew licenses, enforce the one-device rule, prevent fraud and tampering, deliver updates, answer support requests and keep the service running.

7. Who processes it

• Vultr — hosts our license server and its backups.
• Cloudflare — domain name service, this website and forwarding of email sent to our addresses.
• A payment provider, once paid plans go on sale; this policy will name it then.

8. How long we keep it

• Account, device and license records: while your account exists.
• Problem reports: until they are resolved and no longer needed.
• Server backups: replaced daily, the oldest are deleted after 14 days.
• Web server logs (IP addresses of requests): rotated and overwritten automatically.

9. Data on your computer

The app keeps your sign-in and license in %LOCALAPPDATA%\NexusAssetVault and its settings and downloaded plan features in its own profile folder. Signing out removes the session; uninstalling the app can remove these folders.

10. Your choices and rights

You can ask us for a copy of your data, to correct it, or to delete your account and everything linked to it by writing to nexus@polygonsarts.com from your account's email address. Deleted data disappears from backups within 14 days.

11. Children

The app is not directed at children under 13, and we do not knowingly collect their information.

12. Changes

If this policy changes, we will update the date above and, for important changes, tell you in the app before they take effect.
