2) Good thinking!
3) Doesn’t the App Store give you stats on how many people downloaded their app?
Also I’m concerned about “strategic decisions” - so it’s a business behind this app then. What’s the business model? Last time we had a business claiming to unsubscribe you from newsletters... turns out they were actually sharing data with marketing companies, so I’m rightfully concerned.
3/ yes, unroll.me made the wrong calls. But for Jumbo we can’t even access your data, everything happens client-side. You could say that at some point the client will upload all your to our cloud, but that’s really not going to happen. Again, here, how to trust us? First, audits. Second, my reputation. Third, independent researchers would reverse engineering our app, and look at the networks call made. Open for more feedback
Our business model is the one of Dropbox. Pay (you or your employer) for more features.
If your model is a good old “pay for good software” model, then why not just ask what features people want? Why do you feel the need to stalk what people do instead of politely asking?
A verifiable 'code available' license would be a bonus
2/ I said we don't use any (mobile) SDKs from 3-parties analytics, but we do use their backend (Segment, Amplitude). We send the requests from our anonymous proxy directly to their servers.
I was worried that mobile SDKs would leak other data (iOS version, device size, ...) that I don't want to know about. And as a general rule we don't like to use SDK/code from 3parties for security reasons.
3/ We use analytics to track how many users are using the app, and how many users are using the cleaning features. This data does help us to make strategic decisions.
