What is on the site

The articles, illustrations, diagrams and the Lenswork Method toolkit are my work. You’re welcome to quote, link to and share them with a mention of Hallengren’s. The toolkit is for your own work and your team’s; copy and adapt the templates as you like, but please don’t sell it or republish it as a whole.

The articles describe my own experience and my own tests. They are not legal, tax or financial advice. Names of models, vendors and studies are used to say what was tested or cited; none of them sponsor or endorse the site.

Links

Links to other sites are there because I found them useful. I don’t control them and am not responsible for what they say.

Your data

How newsletter sign-ups, bookings, toolkit requests and the site’s statistics are handled is on the privacy page.

Law

French law applies. If we disagree about something, write to me first; most things are solved that way.
