TARAN does *NOT* collect any data.
TARAN does *NOT* send any data anywhere.
There are no tracking cookies, no registration, no hidden "features", etc. -- all this bullshit is against my beliefs, and I personally guarantee that there is none of it, and there will be none.
If you are using a downloaded local copy of TARAN, everything remains on the computer where the browser runs.
If you are using a hosted copy from ptosis.ch, only the web pages constituting the app are downloaded to your device. Strictly nothing is uploaded back to the server.
In future versions I may implement an automated check for updates (upon startup the application will ask the server "what's the latest version you have?"), but this feature will remain strictly opt-in (will be disabled by default, unless you specifically enable it).
