Adblocker privacy

Adblocker-privacy

After scratching the surface with my best Android adblocker review and the tl;dr version of the results I wanted to share a deeper take on the privacy aspect of using adblockers.

The Adblocker Results #2 and deeper insights (longer, recommended version)
Let's get back for a second to the apps that didn't make the cut as the adblocker options I've tested:

  • Free Adblocker Browser - was crashing after start not giving the option to test it at all
  • AppBrain Ad Detector - detects apps on your device which might send your data. Marked Facebook app as highly malicious πŸ™ƒ
  • AdAway - requires root, so it's not an option for everyone
  • TrustGo Ad Detector - asks all possible permissions upfront (how reading my messages or call info would help me stop seeing ads on the web?) which you never should allow unless you're completely sure what you're doing. The irony with the 'TrustGo' name is actually really funny. Trust them all with your data and go away πŸ˜ƒ Uninstalled.

The last app actually brings up an important topic with adblockers - privacy. The thing is, when you allow any adblocker to work on any of your platforms, what you essentially are allowing it is getting access to all your browsing information, so the adblocker can see it and cut out ads and/or trackers. That's why if you don't want your adblocker instead of blocking ads actually use your browsing data for serving you even more personalized ads, make sure you install a trusted one.

As you probably know by now, there are few ways of blocking ads: by using adblocker extensions for Yandex Browser and Samsung Internet browser (and maybe others that didn't cross my eyes), or using a standalone browser like the AdBlock Browser with adblocking already built in. Both ways do their job in a reasonable manner, but what if you're using Google Chrome as your default browser and you don't want to give up bookmarks, passwords and history sync with your Google Account? For that case there is a third option which enables you not only block ads in Google Chrome but block them overall, through your whole system. And it's done by installing a sideloaded apk which creates a local VPN server on the device itself and sends and receives all the Internet traffic through it, filtering it on the fly. How insane is that? Setting a local VPN server on your cellphone - Android never stops impressing me with its crazy hacks.

When you (or in our case the app on your behalf) setup a local VPN, except being able to filter ads and trackers on a much wider scale, throughout the whole system and in all of your apps you'll get two additional advantages if you compare such solution to connecting to the Internet via a traditional remote VPN:

  1. Unlinke remote ones, local VPNs don't consume almost no additional battery power for the same filtering operations
  2. Local VPNs don't add that painful additional delay of your phone transferring all the data through a remote server. As the result you get ad filtering without sacrificing your Internet connection speed.
    But there are few disadvantages as well:
  3. Local VPNs usually don't encrypt your traffic like remote VPNs do, so you don't get that additional layer of security
  4. Your device IP address will still be the same, so you won't be able to go around IP-based resource blocking, Great Firewalls, access restricted websites unlike while using remote VPNs.

That said, when you're using VPNs on Android you have to choose between fast and efficient adblocking or slow but secure Internet browsing. If you know any way that combines the two - please hit me up πŸ™‚

Since usually no one usually would setup a local VPN for blocking ads on their own, that means we'll have to rely on someone's solutions. And by rely I mean trust some company not to use our browsing data in malicious ways. We already have issues trusting big companies like Google, Facebook or Apple which have something meaningful to loose if it turns out they are in fact using our data for their own advantages and without our consent. But what about smaller companies? On one hand for them loosing trust often means just getting out of business, since small companies usually are barely profitable and can't afford loosing any substantial part of their userbase by being involved in privacy scandals. On another hand such companies have more incentive to get those few additional bucks by selling your data in order to survive. And frankly after the latest news of Facebook beating their all time high stock prices even after privacy controversies, it sends a wrong signal to companies which collect any kinds of data that it's okay to leak or sell it - people won't care anyway and investors would still love you.

That being said it means that nobody except you won't really care about your privacy. And even though as mentioned in the first part of the research AdGuard's local VPN does the best job filtering ads not only in Google Chrome that doesn't support adblockers, but in other apps and throughg the whole system in general, people are legitimately concerned about the safety of using any AdGuard's products since their team is actually based in Russia and registered on the non-neutral law-enforcement Cyprus. Even though the openness of the developer and opensourcing their products help a bit, they still don't overcome the overall fear of using any kinds of tools (especially those ones that potentially can snoop your traffic) coming from Russia and that those tools and their developers are considering privacy like they should. Because of that on Android as the adblocker browser extention I would recommend using Adblock Plus which was build as a non-profit organization from the ground up and uses donations to keep developing their product. Having AdGuard's local VPN set to high filtering mode and enablihg https filtering is your best bet against ads but you may risk with your privacy instead. But if you still looking forward to a local VPN you can trust, I highly recommend you another free open-source project Blokada built by a few guys in their spare time that don't have a big company behind them with big expenses that need to be covered by potentially selling end user's data or whitelisting ad companies which usually is another form of income for adblocking companies. Granted AdGuard has a paid Pro iOS app and a subscription business model, but I doubt their earnings from those on a market with generally free adblocking solutions (including their own) is enough for you to trust them with your data.

Best Android ad blocker (July 2018)

Best-android-ad-blocker-july-2018

Recently I had interesting and boring at the same time thing to do: find out which ad blocking options on Android are worth considering.

Starting with a disclaimer: even though all my testings were meant to be objective, some of the results might be inaccurate or non-repeatable. This is mostly due to the nature of the adblocker tests themselves: depending on your Android version, adblocker version and the filter databases state you can and you will get different results than me. In fact your results may vary each time on the same website, like mine did sometimes. Your results may even depend on other apps installed on your device and your device's performance in general. Also I didn't research traffic savings and how secure each adblocking option is - both are separate big topics to discuss on their own and weren't my concerns at the time.

Having that out of the way, here's my setup, testing methodology and short summary of the research.

The Setup
All my tests I ran on a Xiaomi Mi A1 powered by Android One and running Android 8.0 with May security updates. I don't have many apps installed except few messengers and few utility apps (Dropbox, 1Password). I'm not running any VPNs on the device and was using my home private wifi for the consistency of tests.

The Methodology
I used this list of websites to test adblockers. Pi-hole.net in general is a very nice resource that knows and tells how to avoid ads and trackers on the Internet - I highly recommend checking them and their free opensource project.

Not all the websites from the list were even loading, so you will find a shorter list of them in my raw data spreadsheet.

The idea was to go through this selection of websites and each time use a different adblocker or browser. That's what I did and that's what I consider the boring part - opening 12 websites 11 times is not very amuzing πŸ™‚ But what was interesting were the results and what I learned in the process.

The Results (short version)

  • If you're okay with Yandex Browser - free AdGuard Content Browser is probably your only viable option, since there is nothing much else that works with Yandex Browser and also keeps the ads out.
  • If you're rocking Samsung Internet Browser - both free AdGuard Content Blocker and Adblock Plus are good choices, even though I would recommend sticking with Adblock Plus, because of my personal privacy standpoint against AdGuard, on which you can read in the end of this post.
  • Google Chrome users don't have much choice except sideloading (outside of the Play Store) AdGuard for Android or Blokada since Google Chrome doesn't support adblockers. Actually it's a very nice option for everyone, but use it with caution, and read more info on local VPNs. I personally use Blokada out of the two.
  • No good adblocker news to third-party browser lovers out there. Opera Browser has some filtering built in which in my tests are clearly not standing ground against ads like the other solutions. And although Adblocker Browser is doing its job well on par with their own browser extension, their browser experience part is less compelling than Google Chrome or Samsung Internet Browser bring.
  • Nice adblockers remove the ad but leave the frame. Good adblockers remove blank spaces as well. AdGuard and Adblock do the latter.

If you're interested in the privacy concerns of using an adblocker, I highly recommend reading part #2 of my research that focuses on the deeper level of how adblocker function and what you should be aware of while using one.

Why Apple Pay sticker deserves to be 4x size of Visa’s

Apple-Pay-Sticker

Huge Apple Pay sticker recently added below other payment methods

Less than two weeks ago (June 19, 2018) Apple Pay launched in Poland.
And yesterday I noticed a huge Apple Pay sticker on one of the self-checkout point in a local store selling household items.

Apple-Pay-Sticker2

First I noticed the sticker wasn't incorporated into the machine's aesthetics and was added later, probably because the machine was assembled before Apple Pay got introduced. Second thing I noticed there was no Android/Google Pay/Wallet. Last stop - take a look at the size of that Apple Pay's logo - it's huge! and bigger than 2 Visa and 2 MasterCard logo's combined.

The size difference isn't accidental, and it shows the significance of this payment platform before others, even the long-standing traditional ones.

Everything goes mobile, so are the payments. But again, why's there no Google Pay sticker then? Especially when in 2017 out of the 8.8 million phones sold in Poland only 8.5% were iOS devices and a whopping 91.5% were Android.

If you consider Poland's population with almost 38 million people, the mobile usage penetration of 81% you can extrapolate the the numbers above and get:

  • 30.78 M Poles on average have a mobile phone
  • 28.16 M (91.5%) of them are running Android
  • 1.62 M (8.5%) have iOS phones

Please keep in mind though - the figures above aren't really precise, and aren't taking into account cases when one person may have more than one phone, another may have no phone at all, so you can't consider each device as a potential means of payment. Many of the sold devices don't support NFC (used for the payments) either. All numbers exclude smart watches (iOS an Android) and Macs - all enabled with the competing payment systems. Also there are no Windows Mobile numbers, not that anyone buys those anyway ?

What striked me more than the fairly usual market shares are the results of Apple Pay's rollout. In the first 10 days the unofficial number of new Apple Pay users reached 200 000 people! Which is 12.3% of the whole iOS userbase! When out of 28 million Android users within more than 1.5 years a total of 300 000 people (with a mere 1.1%) enabled Google Pay.

As one of the commenters to the news topic said:

Adoption rates proves that Apple has an army, not just a bunch of customers

Which is true and definitely drives the rates. If you ask me, my bank wasn't in the first 8 banks ready at day one, so I went to another one, opened an account there and joined the service.
