Privacy policy
What this site stores, what it does not, and who else is involved.
Last updated: 2026-08-06. This site is operated by Iyan Sanchez, Asturias, Spain. For anything in this policy, write to support@s4nchzz.com.
The short version
There is no account, no login and no server that stores your data. The virtual machines run entirely inside your browser. Disk images you upload are read on your device and never transmitted anywhere — not as a policy choice, but because there is no backend to transmit them to. The only third party involved is Google, for advertising, and only on content pages and only if you agree.
What is stored on your device
The following is kept in your browser's local storage. It never leaves your device and you can erase all of it at any time by clearing site data, or from the app's settings page.
| What | Why |
|---|---|
| Interface preferences (language, density, defaults) | So the app looks the same next time. |
| Saved machine templates | So a machine you configured can be recreated later. |
| Local activity log | So the activity page can show what you did in this browser. |
| Your advertising consent choice | So you are not asked on every visit. |
Running virtual machines, their memory and their disk contents live only in the page's memory and are destroyed when you close or reload the tab.
Advertising
Content pages — the home page, the guides, the glossary and these legal pages — can show ads served by Google AdSense. The advertising script is not loaded at all until you accept, and it is never loaded on the app screens (the machine room, the wizard, the JSON editor, the machine console or settings).
If you accept, Google may set cookies and process your IP address, browser details and the pages you view in order to select and measure ads. Google acts as an independent controller for that processing. You can read Google's privacy policy and manage your ad settings at Google Ad Settings. You can withdraw consent at any time from the cookie policy page.
Hosting and disk images
The site is served by a static hosting provider, and the disk images for the online machines are fetched by your browser from an image host. Like any web request, those requests reveal your IP address and browser details to the provider, which processes them to deliver the file and to keep the service secure. No account or identifying information is attached.
What is not done
- No analytics or visitor tracking of our own.
- No accounts, no email lists, no profiling.
- Nothing is sold or shared with data brokers.
- Your uploaded images are never transmitted anywhere.
Your rights
Under the GDPR you have the right to access, rectify, erase, restrict and object to processing of your personal data, and to data portability. Because this site holds no personal data on any server, most of these are exercised simply by clearing your browser's site data. For anything concerning advertising, contact Google directly, or write to support@s4nchzz.com and we will help. You may also complain to your national supervisory authority — in Spain, the Agencia Española de Protección de Datos (aepd.es).
Children
This site is not directed at children under 14 and collects no data knowingly from them.
Changes
If this policy changes materially, the date at the top changes and consent is requested again where it matters.
