Secure Wipe

No root required. Free and contains no Adware. Does not connect to the internet.

In our continued effort to make this work with KitKat, we released a version (1.08) that crashed on some KitKat devices, presumably those without an external SD Card. Sorry about that. I believe that this new version will prevent that particular problem.

Please provide feedback to the developer rather than giving a low rating so that I can fix whatever is wrong. Also feel free to suggest improvements. Thank you.

It is possible to forensically extract information from a smart phone using mobile forensic tools such as Cellebrite and XRY even after it has been deleted. This utility can help to prevent that from happening by sanitizing the free space on a phone. Similar functionality can be found on desktop machines using utilities like CCleaner, Eraser, and File Shredder. If you are afraid of the government peeking at your phone and extracting and reconstructing deleted files, this is the app that you want.

This application does not delete files or clean the cache. Use other tools such as ES File Explorer and AVG Cleaner to delete files and clean the cache. Then use this utility to sanitize the free space. The free version of this application does not sanitize database areas such as contacts, phone logs, or SMS text messages. Look for a pro version in the future that may perform a more thorough sanitization.

Although we cannot guarantee that all free space will be sanitized, this application finds all of the free space that Android will give us in three primary areas where data is normally stored and overwrites it as completely as the phone will allow:

1. System - This is the protected data area shared by all applications.

2. SD Card - On some phones this is the actual SD Card and on others it is emulated SD Card space.

3. Optional SD Card - On some phones this is the actual SD Card and many other phones do not have this space. Samsung phones typically put the real external SD Card here.

To run the application:

1. Make sure that the phone has good battery/wall power.

2. Put a checkmark next to the sections of memory to sanitize.

3. Press the Start Wiping button.

4. Do not use the phone while the application is working.

The status area will indicate how the process is going.

Some have complained that after a wipe, they sometimes still see old files that were deleted using Hexamob or other similar apps. In my investigation I have found that the overwhelming majority of files are overwritten but occassionally one file is left intact. This could occur if Android does not allow us to write to every free sector. Watch the statistics as it is overwriting to see if the free space count goes to 0 as it is writing. Also run the app more than once to get more thorough wiping since SD cards rotate their sectors in and out of service.

Many SD cards rotate blocks of memory in and out of use for wear leveling. As a result, it is possible that after sanitizing memory there could be some blocks that get rotated back in to use that were never sanitized. To mitigate this possibility, run this application twice which statistically will usually hit all blocks of memory.

This application has not been tested on all phones. Please provide feedback to the developer about any problems. It has been found to work on Samsung Galaxy S2, S3, S4 and Victory phones, the HTC Arrive and others. System space takes several minutes to sanitize and 8GB SD Cards can take up to half an hour. If the application is aborted before it finishes, there may be large files left on the phone. If this happens, simply reboot the phone and bring the application up and it will automatically look for these files and delete them at startup.</div> <div class="id-app-translated-desc" style="display:none">无需根。免费，不包含任何广告软件。不连接到互联网。

在我们继续努力，使这项工作与奇巧，我们发布了一个版本（1.08）即坠毁，机上有些奇巧设备，想必那些没有外部SD卡。我们对此深感抱歉。我相信，这个新版本将阻止特定的问题。

请反馈给开发者，而不是给低等级，这样我可以解决什么是错的。也可以自由地提出改进意见。谢谢。

这是可能的取证使用它已被删除，即使移动取证工具如Cellebrite和XRY智能电话中提取信息。该实用程序可以帮助防止这种情况发生了消毒在手机上的可用空间。类似的功能可以使用像CCleaner的，橡皮擦公用事业台式机被发现，并且文件粉碎机。如果你是怕政府在偷看你的手机和提取和重建被删除的文件，这是你想要的应用程序。

此应用程序不删除文件或清理缓存。使用其他工具，如ES文件浏览器和AVG清洁删除文件和清理缓存。然后使用这个工具来消毒的自由空间。此应用程序的免费版本不消毒的数据库领域，如联系人，通话记录，或发送短信。寻找一个专业版，将来可能会进行更彻底的消毒。

虽然我们不能保证所有的自由空间将被消毒，这个应用程序发现的所有可用空间的Andr​​oid将给我们在数据通常存储和完全的手机将允许它覆盖三个主要领域：

1系统 - 这是所有应用程序共享数据的保护区。

2 SD卡 - 在某些手机这是实际的SD卡和别人是模拟SD卡空间。

3可选SD卡 - 在某些手机这是实际的SD卡和许多其他手机没有这个空间。三星手机通常把真正的外部SD卡在这里。

运行该应用程序：

1，请确保手机有良好的电池/墙上电源。

2，将一个复选标记旁边的内存部分消毒。

3，按开始擦拭按钮。

4，不要使用手机应用程序工作时。

状态区将显示该如何处理是怎么回事。

一些人抱怨说，经过擦拭，他们有时仍然看到的是用Hexamob或其他类似的应用程序中删除旧文件。在我的调查，我发现，绝大多数的文件将被覆盖，但偶尔一个文件保持不变。这可能发生，如果Android不允许我们写的每一个空闲扇区。看统计数字，因为它被覆盖，看是否可用空间计数为0，因为它是写作。同时运行的应用程序不止一次得到更彻底的擦拭，因为SD卡的轮换界别和停止服务。

许多的SD卡轮流在使用磨损平衡和出内存块。因此，它可能是消毒内存后有可能会有一些块，再旋转回来要使用从未消毒。为了缓解这种可能性，运行此应用程序的两倍，这统计学通常会达到的内存中的所有块。

此应用程序还没有经过测试的所有手机。请反馈到有关的任何问题开发商。人们已经发现工作在三星Galaxy S2，S3，S4和胜利的手机，HTC的到达等。系统空间需要几分钟消毒和8GB的SD卡可能需要长达一个半小时。如果在完成之前中止应用程序，有可能是留在手机上的大文件。如果发生这种情况，只需重新启动手机，并把应用程序了，它会自动查找这些文件，并在启动时删除它们。</div> <div class="show-more-end">
