Feature request: Allow unblocking AntiTracker domains, e.g. crash and error-reporting services

[metametapod]

Feature request

Description

I'm interested in blocking tracking domains (without causing breakage) using iVPN's AntiTracker feature, with the exception of crash and error-reporting services. Currently this is not possible, the only alternative is to use a service like NextDNS instead.

Describe the solution you'd like

Some example servers I'd like to exempt:

*.appcenter.ms
*.backtrace.io
*.bugsnag.com
*.crashlytics.com
*.crashlyticsreports-pa.googleapis.com
*.firebaselogging-pa.googleapis.com
*.firebaselogging.googleapis.com
*.raygun.io
*.sentry.io

appcenter.ms
backtrace.io
bugsnag.com
crashlytics.com
crashlyticsreports-pa.googleapis.com
firebaselogging-pa.googleapis.com
firebaselogging.googleapis.com
raygun.io
sentry.io

This is already the stance of some list maintainers, but others block several of these by default.

Describe alternatives you've considered

Right now I am using NextDNS set under iVPN > Settings > Custom DNS for VPN and have AntiTracker turned off.

On Android you can use a hosts-based blocker like AdAway instead, but that's not possible on iOS.

Another workaround for this issue is to use the IKEv2 protocol (either in the app or with a native profile) and then filter DNS on-device e.g. with AdGuard.

Note: The above configuration is only using AdGuard DNS protection (which intercepts traffic via a device VPN), not the AdGuard VPN that is also offered within the app. This is the same method AdAway uses on Android for devices that aren't rooted.

To prevent leaks, use an IVPN DNS server (currently 10.0.254.1 for regular DNS):
