@Petrichorwheels nothing has been implanted. CycleChat will store a cookie if you tick the box to remember your login, remember your CC cookie choice, and the additional advertising consent pop-up will store a cookie with your choices. If you don't wish to consent to personalised ads, simply click the
manage options button and turn off the eight legitimate interest sliders. Click
Confirm choices to save and that should be that. (
There is no need to change any of the 170+ ad agency preferences if you have not enabled any of the main consent sliders.)
Once set, both of these should work in the background and not regularly pop back up, however, clearing browser cache/cookies will likely clear the choices you've made and you'll need to re-tick to remember your login, and confirm your CycleChat cookie and redo the slider choices for the ads consent.
Whatever else is happening on your device it is unlikely to be related to visiting CycleChat.
I have no interest in collecting anyone's personal data and in the 15+ years I've been running CycleChat I've never once spammed anyone or planted anything on their devices. Ultimately, if you're not happy with CycleChat other cycling communities are available.
Cheers,
Shaun
