FAQ for Logging

Q. What do you LOG?
A. The answer is split in 5 parts:

A1. Savings Logs: We record the savings accumulated per file type (mime-type) per hour; after a month it is aggregated into one record “last month’s savings”. i.e. if we help you to save 10 Kb. of data in “image/gif” files. We don’t really know if that saving was due to one file, two or a dozen, no the domain name, URL, or any other specific.

A2. Blocking Logs: We record every time we block a page, i.e. when you try to enter to a phishing site, this data is handled in a similar way as A1 and used to give feedback to you.

A3. VPN Traffic: We record how much data your send and receive from the VPN. This is for metering and limiting purposes (on free accounts) we remove the records as soon as it is not more meaningful.

A4. Android Client: We record you network mac-address, “android id” and phone id (IMEI); These ids are unique, they work like a key for your account; We can remember your settings and subscriptions, without actually having to ask you for your real name, personal details or username and password. Even if you pay for the service via Google Play, we can’t obtain your personal details. Because we are not asking for personal details, we reserve the right to ask for them via in-app messaging if we consider there is abusive behavior on your account.

A5. Internet Addresses IP, time, etc: No, we don’t record any.

FAQ for Compression

Q. How does the Web-Compression work?
A. We re-compress images before they reach your mobile and that can reduce up to 80% of your data-plan. We also enforce GZIP compression on the rest of the web-content; you would be surprised with how many websites don’t do basic compression on its content (at July/2014 bbc.co.uk, bing.com, adobe.com, etc. don’t honour GZIP headers); we do the compression before it reaches your device so you keep your data plan at a minimum. This reduction is customisable and fully optional. There are similar services on the internet like Opera MAX, or Onavo, we do exactly the same thing as they do, but our business model is based on privacy, we don’t make money by selling your browsing data, that is why we have to charge for the service.

Q. Do you compress video or audio?
A. Not yet, but it is on the pipeline, ask us please if you are interested.

Q. Do you compress HTTPS / Secure pages?
A. No. It is technically impossible, what goes between your browser and the secure server is impossible to decode.

Q. Why I can change the compression settings?
A. You can leave them on the default values which offers a good balance between savings and quality. Perhaps, you are on a very slow connection, or reaching your limit of you data plan or it might be your battery is dying; setting the compression at maximum will off-load most of your mobile “heavy lifting” to our servers. This will save you battery and data-plan (less gsm-radio and cpu used as less data is transferred and processed).

FAQ Blocking

Q. How the phishing and blocking system works?
A. We integrate databases from multiple malware monitoring networks. When your device makes a request to a allegedly reported URL, it will blocked automatically before it reaches your device. You will see a ‘403 Forbidden’ error page.

Q. Does it work on HTTPS / Secure pages?
A. No. It is technically impossible. Keep in mind, in order to obtain a secure site certificate the applicant has to provide proof of id, address, and company details. In practice, secure pages are more less likely to be used to distribute malware or phishing. Nevertheless, we will be integrating a DNS blocking soon that can alleviate this further.

Q. Which sources do you use for blocking sites and how often do you update them?
A. At the moment we integrate many different sources: PhishTank, malwareblacklist, surbl.org, malwaredomainlist.com, etc. The list can change from time to time.

Q. How often do you update the blocking lists?
A. Up to 300 times a day or even more, we try to keep our feeds as updated as possible. Different databases get updated at different times during the day, but on a typical day there are more than 300 updates. We pride ourselves of being one of the unique systems that integrate so many different sources, no web-browser is that active.

Q. I think it is a false positive, can I unblock it?
A. Yes, you can always unblock the protections from the settings page, please proceed with caution.

Q. Can I use Torrent?
A. At the moment bittorrent is open to use in our network. We like bittorent and we consider it to be an efficient way to transfer files on the internet. Nevertheless, we deal with DCMA compliances and we might consider blocking bittorrent traffic to maintain costs under reasonable level. Unfortunately DCMA complains generates plenty of admin costs, you might want to talk with your representative to express this fact. TL/DR we don’t block torrents but might in the future if the amount of complains increases, we can’t afford the costs.
