How Decision Trees uses information about the staff who use it. Last updated 6 November 2026.

Who we are

Decision Trees is an internal knowledge base and training site run by Harrap Computer Systems Ltd (trading as Libresoft) for our own staff. We are the data controller for the personal information described here. If you have a question about it, or want to use any of your rights below, speak to your manager or email the person who looks after data protection at Harrap.

What we record about you

What we don’t record

Why we use it

To run the site and keep it secure, to keep a record of changes to our working guides, and to help make sure everyone has the training they need for their job (including required health and safety training). This is part of our legitimate interests as your employer and, for required training, our legal obligations. The fun extras are optional.

Who can see it

Where it is kept, and for how long

Everything is stored on our web host in the UK. A full backup is made each day and kept for 14 days. Your account and its records stay while you work here. When you leave, an admin removes your account, which deletes your training, onboarding and skills records, game scores, sticky note, votes, the shout-outs you gave and your team memberships. The change log, and any feedback you left on guides, keep your name, because they are part of the guides’ history.

If someone connects an AI assistant using a key they made on the site, the guides it reads or changes pass through that AI service under their account.

Your rights

You can ask for a copy of the information we hold about you, ask us to correct it, and in some cases ask us to delete or stop using it. You can also complain to the Information Commissioner’s Office (ico.org.uk) if you are unhappy with how we handle it, though we’d like the chance to put it right first.
