Hey there! Sentry is only used to detect errors automatically if they occur on your device. It is an opt-in feature, and you can disable it or enable it at any time. This information is useful for me to determine if there are any large scale issues that come up due to a recent release and allows me to quickly take actions which might otherwise take longer to detect.

I opted to include this as this is still a very early alpha release, and having this allows me to bring better and less error-prone releases to everyone! Eventually, as this app progresses from alpha to a more stable version, I will most likely remove it as it'll be less useful for me overall

You can disable Sentry reporting. Don't think it's even enabled by default.

It asks whether you want to enable sentry at first start and you can enable/disable it anytime in the settings too. I'd also like a tracker-free version on F-Droid long term, but for now this is okay for me personally.

It's opt in, not opt out, so you can decide to allow it or not.

Calling Sentry spyware is a bit of stretch. It’s debugging telemetry.

Not the developer, but there's an option in the settings to turn Sentry error tracking off. I don't remember if it was enabled by default.

I have 0 log about thunder tries to send data to sentry or any other log service
