Impulse App Charged After Free Trial – Refund Requested

I recently discovered that a paid subscription for the app “Impulse – Gehirntraining” has been charged to my account via the Apple App Store, although I never knowingly agreed to a paid subscription. I only remember signing up for what I believed to be a free trial and did not agree to any ongoing paid plan. On 21.05.2026 the first fee for this Impulse subscription was debited from my account, and further amounts followed. The attached account overview shows, among other things, charges of €14,99 and €30,56 twice to “mental-impulse”. As soon as I became aware of this, I cancelled the subscription, but I had to notice that charges continued to be made afterwards. From my point of view these debits are unjustified, as I did not explicitly consent to a paid subscription and cancelled as soon as I found out about it. I therefore request a full refund of all fees related to this Impulse subscription and the final cancellation of my subscription so that no further payments are collected in the future. I also require a clear written confirmation that all past and future fees have been cancelled. If I do not receive this confirmation and my money is not refunded, I will be forced to consider legal action. I expect a prompt response and a quick solution to this problem.
