Because...
The SPPAS software tool is reliable: the application performs the features
that the documentation described. It can tolerate the user making mistakes or using the
software in unexpected ways: in that cases an error identifier with an error message is
displayed. Its performances are good enough for the required uses cases, under the expected
load and data volume.
SPPAS is installed on your computer: your corpus won't be transferred on
the web. No statistics, no personal data are collected.
Its ongoing maintenance by the author: fixing bugs, keeping its systems
operational, investigating failures, checking it on 3 platforms, modifying it for new
use cases, adding new features and last but not least adding new language resources, updating
the documentation and the website.
SPPAS is an open source package. You can edit the source code of the software tool,
you can modify it, you can re-distribute it, etc.
