Usage statistics

By default PsychoPy attempts to ping this webserver each time you launch the application. This can be turned off in preferences but please don't! See Privacy Information for details.

The statistics below underestimate usage in the following ways:

• some users never launch the app; they write their Python code in a separate editor and run it from the terminal
• some users turn off internet connections on their experiment computers
• some users are behind aggressive company firewalls and PsychoPy can't always find the proxy server

Users per month

NB: Linux users are likely a higher proportion than this, but they are especially likely to run Psychopy scripts without launching the actual application (so their stats are not recorded).

By version

Privacy Information

The only information sent to the server is the version of PsychoPy you're using, and info about your operating system. There is nothing that identifies you (e.g. username) or provides any personal information about you. The IP address is also received (as with any time you access a web page from your browser) but this is immediately "hashed" so that it can't be used except to identify 'unique' users.

(NB. Every time you look at any web page in your browser you provide the owner of that page with much more information than this!)

The information received will only ever be used for the development of PsychoPy. It will never ever be sold or passed on to other companies for other purposes.
