Privacy Policy

Last updated: 30 September 2026

This policy covers the SubnetFast website at subnetfast.com. In short: there are no accounts, your settings and results stay on your device, and the only data leaving your device is anonymous website statistics.

What stays on your device

Your settings, saved profiles, lifetime stats and flashcard progress are stored only in your browser's local storage. They are never sent to us or anyone else. You can remove them at any time with "Clear my stats" or "Reset progress", by deleting profiles, or by clearing the site's data in your browser.

Export files are created on your device and only go wherever you choose to save or share them.

Website statistics

The website uses Vercel Web Analytics to count visits. It uses no cookies and records only anonymous, combined statistics: the page visited, the referring site, approximate location (country, region, city), browser, operating system and device type. Visitors are counted using a temporary code made from the request, which is discarded after 24 hours and is not linked to your IP address or identity.

Our host, Vercel, also processes technical data such as IP addresses to deliver the website and protect it from abuse.

If you email us

If you contact us, we receive your email address and message and use them only to reply. We do not add you to any mailing list.

What we don't do

• We don't require or offer accounts.
• We don't sell your personal information.
• We don't share data with anyone beyond the services named above.

Children

SubnetFast is made for students and IT professionals and is not directed at children under 13. We do not knowingly collect personal information from children.

Changes

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