Apps & Games content ratings on Softonic

Content ratings help you understand the type of content you might find in an app or game, so you can decide if they are suitable for you and your family.

What do the ratings actually tell me?

Content ratings describe the minimum age we feel the content is suitable for. It does not indicate that the app was specifically designed for that particular age, or if a certain level of skill is required to play the game or use the app.

Where can I find the content ratings?

You will find the content ratings on every app or game page.

Why are some apps or games unrated?

If an app or game does not have a rating, it means that it has not yet been rated, or it’s been rated and we’re working to update the page.

Rating Systems

Softonic uses the rating systems by PEGI and ESRB. The ratings you see may vary by country or region.

Recent changes

  • Major bugfixes:
  • · Avoid an assertion failure when reloading a configuration withTrackExitHosts changes. Found and fixed by 'laruldan'. Fixes bug3923; bugfix on

  • Minor features (security):
  • · Check for replays of the public-key encrypted portion of anINTRODUCE1 cell, in addition to the current check for replays ofthe g^x value. This prevents a possible class of active attacksby an attacker who controls both an introduction point and arendezvous point, and who uses the malleability of AES-CTR toalter the encrypted g^x portion of the INTRODUCE1 cell. We thinkthat these attacks are infeasible (requiring the attacker to sendon the order of zettabytes of altered cells in a short interval),but we'd rather block them off in case there are any classes ofthis attack that we missed. Reported by Willem Pinckaers.

  • Minor features:
  • · Adjust the expiration time on our SSL session certificates tobetter match SSL certs seen in the wild. Resolves ticket 4014.
  • · Change the default required uptime for a relay to be accepted asa HSDir (hidden service directory) from 24 hours to 25 hours.Improves on; resolves ticket 2649.
  • · Add a VoteOnHidServDirectoriesV2 config option to allow directoryauthorities to abstain from voting on assignment of the HSDirconsensus flag. Related to bug 2649.
  • · Update to the September 6 2011 Maxmind GeoLite Country database.

  • Minor bugfixes (documentation and log messages):
  • · Correct the man page to explain that HashedControlPassword andCookieAuthentication can both be set, in which case either methodis sufficient to authenticate to Tor. Bugfix on,when we decided to allow these config options to both be set. Issueraised by bug 3898.
  • · Demote the 'replay detected' log message emitted when a hiddenservice receives the same Diffie-Hellman public key in two differentINTRODUCE2 cells to info level. A normal Tor client can cause thatlog message during its normal operation. Bugfix on;fixes part of bug 2442.
  • · Demote the 'INTRODUCE2 cell is too {old,new}' log message to infolevel. There is nothing that a hidden service's operator can doto fix its clients' clocks. Bugfix on; fixes partof bug 2442.
  • · Clarify a log message specifying the characters permitted inHiddenServiceAuthorizeClient client names. Previously, the logmessage said that "[A-Za-z0-9+-_]" were permitted; that could havegiven the impression that every ASCII character between "+" and "_"was permitted. Now we say "[A-Za-z0-9+_-]". Bugfix on

  • Build fixes:
  • · Provide a substitute implementation of lround() for MSVC, whichapparently lacks it. Patch from Gisle Vanem.
  • · Clean up some code issues that prevented Tor from building on olderBSDs. Fixes bug 3894; reported by "grarpamp".
  • · Search for a platform-specific version of "ar" when cross-compiling.Should fix builds on iOS. Resolves bug 3909, found by Marco Bonetti.
  • Easy to switch to anonymous mode
  • Installation takes you clearly step by step
  • Can't guarantee anonymity
  • Sometimes can take a while to connect to Tor network
