I’ve been using skiff. com for sometime, as they claim to be a fully privacy preserving app suite like GApps or proton. One thing I like is they provide 10GB storage even for free accounts, where proton eventhough much bigger provides only 500MB.
But that got me wondering… Are they trustworthy as proton? Is there a chanve they end up being a honeypot? Does data actually gets encrypted before sending to the servers in a trustworthy way?
- I don’t like that you have to use play store to install their apps. ‘Oh, but I use Aurora store’ you say. Doesn’t matter, the email app (the only one I checked) uses the play billing api and firebase installations so on first run it phones home to the mothership. - Someone pointed that out on the other site, and the owner jumped in and said ‘those are disabled’. Then someone else posted firewall logs. - Edit: I realized that what I wrote in now way answers you question, mea culpa. Tutanota wrote a comparison Here that does though. It seems relatively unbiased, judge for yourself. - Fwiw I use both Tutanota and Proton. They also have the advantage of being outside of Five Eyes countries. - Edit: word - uses the play billing api and firebase installations so on first run it phones home to the mothership - Ooh yikes 
- Aurora store doesn’t even work anymore… Btw you can pay using the web interface too? Do we need play billing API? - I just used Aurora store to download Skiff Mail before I posted this. Definitely worked a few hours ago. - Aurora works but the rate limiting on the anonymous accounts is getting tough. I need to switch accounts multiple times before I can even get one search in - I guess I got lucky, I hadn’t used it in a long time and it worked right away after I unblocked the googly from my firewall. - I just wanted to check Skiff again to see if anything had changed. It was good though, Aurora said I had a few updates, and I thought ’ cool, I can delete those things’. I use Kiss launcher, which I love, but not having everything in front of you I sometimes forget less used apps. 
 
 
 
- Both Tutanota and photon mail are proprietary - Edit: Apparently Tutanota us working on becoming librejs compliant 
 
- I’ve never heard of Skiff. Beyond studying the protocols and system design, here’s a couple of things off the top of my head to help: - Follow the money. Are they charging enough to not be tempted to sell data about their users?
- Who is in charge? Have leadership demonstrated respect towards their user’s privacy in the past? See their About Us page
- Read their privacy policy
- Keep up-to-date. Lots of services start out with good intentions, but over time they get acquired, acqui-hired, big investments… and policies change.
 
- deleted by creator - I hope they at least are doing the E2EE thing… Last thing I want is to know that they could in fact read the decrypted data… - Are they open source? - Skiff is pretty good, I switched from proton over as they had a good one year promo and I found it fits better on what I need. The drive and page setup is pretty good too and so is the calendar. Overall I like skiff and they update and add a lot almost weekly. Big fan so far - Their open soruce only has skiff mail, what about the otther products? - Skiff licensed all of it’s apps it at CC-BY-NC-4, why not change it for GPL 3.0 to make it a real free and open source software that respects user’s freedom and mandates the fork to be free and open source. There’s a difference between free software, open source and source available! - I presume the reason they didn’t use GPL3 is because they wanted the attribution and non-commercial clauses offered by CC-BY-NC. - Not suggesting that they should not prefer to drop those clauses in favour of a copyleft free software licence. but you asked “why not” and losing those clauses is clearly an obvious candidate for why they might not want to. - A software using CC-BY-NC-4 is not a good option, as it was made for media. If skiff markets itself as open source, it should respect the guidelines of opensource( it’s open source(https://opensource.org/osd/), you can read the 6th rule. It says the software should not be limited for commercial use.) - I agree, I’m just answering the why question. Free software licenses don’t have non-commercial clauses and they want an NC clause. 
 
 
 
 
 
 
 
- They don’t seem as transparent as tutanota
