What currency am I charged in? Euro, the same amount you see on this page. The dollar figure is only there for comparison.
Can I stop whenever I like? Yes. Both plans can be cancelled at any time, and the monthly plan has no minimum term.
Is the annual plan better value? Over a year it works out at about €6.75 a month, compared with €8.99 on the monthly plan, and it adds priority support and early access to new features.
Is this a replacement for counselling? No. It's an emotional support chat, not therapy. If you have a medical card, ask your GP about free HSE counselling through the CIPC service.
