<p>If you want to use Yaffs on an Open Source project, then go ahead and <a href="/downloads">download</a> the GNU General Public Licence v.2 now. You can get it straight away from the link on the right of the page.</p>

<p>Yaffs is also available under a Commercial Licence&nbsp;for projects that don't want to disclose their source code.&nbsp; This Licence does not have the obligations of GPL, but is perpetual, world-wide, non-exclusive and carries no continuing royalty.</p>

<p>You can use the Open Source code to investigate and evaluate Yaffs, then before shipping your product to anyone outside of your organisation you buy a licence from Aleph One which does not have the GNU GPL obligation to release your Source Code.&nbsp; Contact&nbsp; sales@aleph1.co.uk&nbsp; for more information or have a look at our <a href="/downloads">licensing information</a>.</p>
