Ever wanted to make a joke to a friend? This is the right app for you!
The e-mails will not contain ANY sign of your identity, so you're totally safe.
It can be used to joke, but sometimes it can also be useful when normal e-mail softwares are not working (firewalls, etc), or to send out a fast e-mail without having to configure your mailbox on that specific device.
This is a pay app, the money I will get from it will help me to maintain the mail server.
Test before you buy! Download PrivateCalls Trial (https://play.google.com/store/apps/details?id=at.prm.privatecalls.lib&hl=en) from Google play. It is fully functional, however, with limited lifetime.
For a more detailed description and some examples please visit my website. PrivateCalls uses operator-specific prefixes and works in many countries around the world. My website contains a list of provider specific codes to hide your caller-id for different operators in different countries. If your country or operator is not on the list, just ask your operator for the code and send me an email to put it on the list. The hiding of the caller-id is an operator-specific feature, and sadly, not all operators provide this.
Please note: PrivateCalls does nothing you could not dial manually - it is not the fault of my app, if it is not possible to hide the caller id in your country or with your phone operator. Hiding the caller-id most likely does not work in India, see homepage for details. Please do not give bad ratings for PrivateCalls if the feature is not available in your country! General rule: if you can not dial it manually (without my/any app) then it will not work with my/any app either!
If you have any questions, do not hesitate to contact me, the links for both website and email are placed below. Please do not ask questions or report bugs in the ratings. I would deeply appreciate any ratings!
KEYWORDS: hide caller-id, hide phone number when calling, private calls, anonymous calls, anonymous number, privacy, prefix, prefixes, suffix, suffixes, change number, modify number, secret calls.
Why does PrivateCalls request permissions?
PrivateCalls request permissions to do things for you. The permissions and the actions performed with these permissions are described below:
PROCESS_OUTGOING_CALLS: You dial a number, PrivateCall modifies the number according to the rules you defined in the PrivateCalls settings and finally, your phone actually establishes the connection. Technically, this permission enables PrivateCalls to perform a phone call. Guarantee: There are no hidden modifications to your numbers. All modifications are described on this page and only the prefixes you specify are added to your numbers. PrivateCalls never makes any phone calls on its own, it just intercepts your calls and modifies your numbers as you command.
READ_CONTACTS: This permission is used to read the contact groups on your phone (for displaying the lists of contact groups in the settings menu) and to lookup the number you dialed in your phones contact list. Guarantee: Your contacts are never modified (it is a read-only permission). And your contacts are safe, they are neither processed in any way differing from the description on this page nor transmitted anywhere.
RECEIVE_BOOT_COMPLETED: Automatically start PrivateCalls when your phone starts.
READ_CALL_LOG/WRITE_CALL_LOG: Permission necessary to replace the modified number with the number originally dialed.
READ_PHONE_STATE: The call log is modified, after the current call has ended. Therefore, PrivateCalls needs to read the current phone state.
What versions of Android are supported?
PrivateCalls is available with Android 4.0, 4.1, 4.2, 4.3 and 4.4.

Here is the theory behind SpoofKiller:
Viewing the problem of spoofing from the perspective of the attacker, it becomes evident that in order to be successful, the attacker has to both (1) trick his victim, and (2) benefit from the actions of the victim. While this may seem redundant to call out, it is crucial to the understanding of how to defend against spoofing.
Typical anti-spoof technologies relate to the first of these two phases; they either provide positive indications for good sites (such as the SSL lock, or coloration of URL address bars on sites with EV certs); or they provide negative indications for bad sites (such as popups warning the users of blacklisted sites.) This is not a successful approach as it depends on the awareness and judgment of the user.
Spoofkiller addresses the problem by relating to the second phase: it makes certain that an attacker that has managed to trick the victim does not benefit from the actions of the victim. “Being tricked”, in the context of a spoofing attack, means to carry out the same set of actions as would have been carried out on the legitimate counterpart of the spoofed site (or app). Therefore, the very same user action must result in login success on a good site, but failure to collect credentials on a bad site. This, at first, appears counter-intuitive or even impossible, but turns out to be possible to achieve and deploy without any infrastructure changes.
Spoofkiller causes different results given the same user action. This is achieved by identifying whether a webpage (or app) is on a whitelist when a user signals that he or she is about to log in. Whitelisted webpages/apps are then allowed to proceed to execute (which results in a login), while those that are not whitelisted are interrupted by the browser or operating system. Special cases are managed to deal with good webpages/apps that are not whitelisted; and to message users who have not yet learnt (the slightly modified) login procedure. The new login procedure involves pressing a hardware button, such as the power button. (While this may at first seem to cause additional friction, convenience features can be added to this action to incentivize users to use the Spoofkiller functionality.)
Very broad patent coverage has been obtained. A deployment strategy has been developed, in which PayPal, the owner of the intellectual property, provides free licenses to any company, to encourage adoption. (The only provision would be that PayPal be on the whitelist of the solution; the relevance of the whitelist is described below.) This would not provide PayPal with any direct revenue, but it is expected to result in a large indirect benefit due to the marketplace being more secure. As such, it would benefit everybody in the marketplace, except the fraudsters, of course.
SpoofKiller was developed by Markus Jakobsson, Principal Scientist of Consumer Security at PayPal. See www.markus-jakobsson.com. ZircoSecure was developed by Markus Jakobsson and Hossein Siadati.
