I'd be happy to. In summary, there are three things Spectre uses your Internet connection for when you use the app:
- Crash reporting (using the privacy-first service Sentry), off by default, on if the user enables Diagnostics.
- Anonymous statistical analytics (using a self-hosted privacy-first Countly instance), off by default, on if the user enables Diagnostics.
- Site previews (end-to-end, loads a picture for your sites, akin to a social banner on a link), on by default, no outgoing data.
