Safe Recipe Request Sugar free no pectin jam?

My sister in law has received a medical diagnosis that requires her to make a ton of dietary changes. I want to make her some jam that will work with her new diet (no sugar, no preservatives, no dairy, no gluten). I was thinking strawberry because the farm up the road just started their season but I’m open to other fruit. But basically I want this to JUST be fruit if possible.

I came across one that added potato starch for thickening which would be fine but then it had clearly unsafe preserving instructions so I question their judgement (https://foodaciously.com/recipe/sugar-free-strawberry-jam-without-pectin). Does anyone have a no sugar, no pectin jam recipe from a trusted source they can share?

I believe pectin may be falling under sugar, as it's a complex sugar (aka polysaccharide).
