Brave ships with Google's push messaging service disabled by default for privacy. The Web Push API used by De Kind (and most other web apps) routes through Google's service under the hood, so when you click Enable notifications Brave refuses to talk to it and you see a message that the push service refused the subscription.
This is a Brave-wide setting, not a De Kind bug. Parent B and other users on Chrome, Edge, Firefox, or Safari will not see this issue.
Fix
- Open a new tab in Brave and paste
brave://settings/privacyinto the address bar. - Scroll to Privacy and security.
- Find Use Google services for push messaging and toggle it on.
- Close and reopen Brave completely. The toggle only takes effect on restart.
- Return to De Kind, go to Settings → Notifications, and click Enable notifications again.
If you prefer not to enable Google's push service
Some Brave users deliberately leave this off to avoid Google connectivity. In that case, web push from De Kind won't work on this browser. You have two options:
- Use a different browser (Chrome, Edge, or Firefox) for De Kind.
- Rely on the in-app notification badge — every action still shows up in De Kind's notification list when you next open the site.
