Proprietary software is software that grants its creator, publisher, or other rightsholder or rightsholder partner a legal monopoly by modern copyright and intellectual property law to exclude the recipient from freely sharing the software or modifying it, and—in some cases, as is the case with some patent-encumbered and EULA -bound software—from making use of the software on their own, thereby restricting their freedoms.
44-458: Google Play Services is a proprietary software package produced by Google for installation on Android devices. It consists of background services and libraries for use by mobile apps running on the device. When it was introduced in 2012, it provided access to the Google+ APIs and OAuth 2.0. It expanded to cover a variety of Google services , allowing applications to communicate with
88-476: A trade secret . Software can be made available with fewer restrictions on licensing or source-code access; software that satisfies certain conditions of freedom and openness is known as " free " or " open-source ." Since license agreements do not override applicable copyright law or contract law , provisions in conflict with applicable law are not enforceable. Some software is specifically licensed and not sold, in order to avoid limitations of copyright such as
132-507: A "mixed source" model including both free and non-free software in the same distribution. Most if not all so-called proprietary UNIX distributions are mixed source software, bundling open-source components like BIND , Sendmail , X Window System , DHCP , and others along with a purely proprietary kernel and system utilities. Some free software packages are also simultaneously available under proprietary terms. Examples include MySQL , Sendmail and ssh. The original copyright holders for
176-523: A February 21, 1997, internal Microsoft memo drafted for Bill Gates : Early versions of the iPhone SDK were covered by a non-disclosure agreement . The agreement forbade independent developers from discussing the content of the interfaces. Apple discontinued the NDA in October 2008. Any dependency on the future versions and upgrades for a proprietary software package can create vendor lock-in , entrenching
220-467: A Government Security Program (GSP) to allow governments to view source code and Microsoft security documentation, of which the Chinese government was an early participant. The program is part of Microsoft's broader Shared Source Initiative which provides source code access for some products. The Reference Source License (Ms-RSL) and Limited Public License (Ms-LPL) are proprietary software licenses where
264-658: A closed-source model. Many apps (such as Lyft , Uber , and many of the Google apps like Gmail and YouTube ) function only when the Google Play Services package is available and enabled. Distributing Google Play Services as a part of the Google Apps package requires a license from Google, which contractually prohibits device producers from producing Android devices that are incompatible with Google's Android specifications. Others who are interested in modifying
308-401: A copy can decide whether, and how much, to charge for a copy or related services. Proprietary software that comes for no cost is called freeware . Proponents of commercial proprietary software argue that requiring users to pay for software as a product increases funding or time available for the research and development of software. For example, Microsoft says that per-copy fees maximize
352-400: A custom ROM. OpenSignal acknowledged that while this made it problematic to develop apps, the wide variety of models allows Android to enter more markets. Developers have placed the blame on Google and the hardware manufacturers, while Google has blamed software developers for not staying within the guidelines of its terms and conditions. The issue with fragmentation has forced Google to add
396-531: A firm offers multiple incompatible versions or variations of a single product, either in tandem or over time as a result of accumulated changes to product specification . Android usage fragmentation as of 10 Apr 2020. iOS usage fragmentation as of 10 Dec 2020. A term being used in the Android development community is Android fragmentation . Fragmentation within Android is when a variety of versions of
440-564: A license for the Internet forum software vBulletin can modify the source for their own site but cannot redistribute it. This is true for many web applications, which must be in source code form when being run by a web server. The source code is covered by a non-disclosure agreement or a license that allows, for example, study and modification, but not redistribution. The text-based email client Pine and certain implementations of Secure Shell are distributed with proprietary licenses that make
484-479: A license from Google, which contractually prohibits device producers from producing Android devices that are incompatible with Google's Android specifications. Google Play Game Services can be used by application developers to allow a competitive and social experience through the use of leaderboards, achievements , and multiplayer sessions. Saved Games API is available to sync game saves on Google's cloud infrastructure . Location APIs provide specifications about
SECTION 10
#1732802526235528-560: A monopoly position. Proprietary software may also have licensing terms that limit the usage of that software to a specific set of hardware. Apple has such a licensing model for macOS , an operating system which is limited to Apple hardware, both by licensing and various design decisions. This licensing model has been affirmed by the United States Court of Appeals for the Ninth Circuit . Proprietary software which
572-458: A prohibition to its terms and conditions for its software development kit , which developers must accept before developing for the Android operating system. For example, OpenSignal and Testdroid studies have found out that OEMs fragment Android ecosystem significantly more than Google. You agree that you will not take any actions that may cause or result in the fragmentation of Android, including but not limited to distributing, participating in
616-501: A single product to commit to an entire product ecosystem , rather than maintaining free choice of complementary products and services. Two common varieties of fragmentation are market fragmentation and version fragmentation . Fragmentation is the opposite of, and is solved by standardization . Market fragmentation happens when multiple competing firms offer highly-incompatible technologies or technology stacks , likely leading to vendor lock-in . Version fragmentation happens when
660-481: A single user or computer. In some cases, software features are restricted during or after the trial period, a practice sometimes called crippleware . Proprietary software often stores some of its data in file formats that are incompatible with other software, and may also communicate using protocols which are incompatible. Such formats and protocols may be restricted as trade secrets or subject to patents . A proprietary application programming interface (API)
704-462: A software package may be ended to force users to upgrade and pay for newer versions ( planned obsolescence ). Sometimes another vendor or a software's community themselves can provide support for the software, or the users can migrate to either competing systems with longer support life cycles or to FOSS -based systems. Some proprietary software is released by their owner at end-of-life as open-source or source available software, often to prevent
748-425: A technical measure, such as product activation , a product key or serial number, a hardware key , or copy protection . Vendors may also distribute versions that remove particular features, or versions which allow only certain fields of endeavor, such as non-commercial, educational, or non-profit use. Use restrictions vary by license: Vendors typically distribute proprietary software in compiled form, usually
792-406: A work of free software, even copyleft free software, can use dual-licensing to allow themselves or others to redistribute proprietary versions. Non-copyleft free software (i.e. software distributed under a permissive free software license or released to the public domain) allows anyone to make proprietary redistributions. Free software that depends on proprietary software is considered "trapped" by
836-484: Is a software library interface "specific to one device or, more likely to a number of devices within a particular manufacturer's product range." The motivation for using a proprietary API can be vendor lock-in or because standard APIs do not support the device's functionality. The European Commission , in its March 24, 2004, decision on Microsoft's business practices, quotes, in paragraph 463, Microsoft general manager for C++ development Aaron Contorer as stating in
880-523: Is automatically updated through Google Play on devices with Android 6.0 or newer. This means Google can deliver updates without manufacturers having to update the Android firmware, working around the fragmentation of the platform that has become infamous for Android products. The Android Open Source Project (AOSP) was announced in 2007, and functioned as the baseline system for all OEMs and firmware modifications such as CyanogenMod and LineageOS . Various AOSP apps were transferred to Google Play with
924-489: Is no longer marketed, supported or sold by its owner is called abandonware , the digital form of orphaned works . If the proprietor of a software package should cease to exist, or decide to cease or limit production or support for a proprietary software package, recipients and users of the package may have no recourse if problems are found with the software. Proprietors can fail to improve and support software because of business problems. Support for older or existing versions of
SECTION 20
#1732802526235968-436: Is not synonymous with commercial software , although the two terms are sometimes used synonymously in articles about free software. Proprietary software can be distributed at no cost or for a fee, and free software can be distributed at no cost or for a fee. The difference is that whether proprietary software can be distributed, and what the fee would be, is at the proprietor's discretion. With free software, anyone who has
1012-400: Is required for another party to use the software. In the case of proprietary software with source code available, the vendor may also prohibit customers from distributing their modifications to the source code. Shareware is closed-source software whose owner encourages redistribution at no cost, but which the user sometimes must pay to use after a trial period. The fee usually allows use by
1056-515: The Google Fit API, account authentication methods, and Google Analytics . Google Play Services is used by almost all Google apps that have system-level powers. All major Android services are controlled by Google Play Services, and many third-party apps also depend on it. Without this and its requirement to log in with a Google Account, apps may not work properly. Google Play Protect is a unification of Android security systems. In 2019,
1100-425: The first-sale doctrine . The owner of proprietary software exercises certain exclusive rights over the software. The owner can restrict the use, inspection of source code, modification of source code, and redistribution. Vendors typically limit the number of computers on which software can be used, and prohibit the user from installing the software on extra computers. Restricted use is sometimes enforced through
1144-468: The machine language understood by the computer's central processing unit . They typically retain the source code , or human-readable version of the software, often written in a higher level programming language . This scheme is often referred to as closed source. While most proprietary software is distributed without the source code, some vendors distribute the source code or otherwise make it available to customers. For example, users who have purchased
1188-426: The Android platform, combined with a mixture of hardware result in the inability for some devices to properly run certain applications. Despite Google upgrading its Android operating system to version 4.4, also known as KitKat , users continued to use the earlier versions of the operating system, primarily Gingerbread (that's as of 2018 down to 0.3% share). The cause is primarily because hardware manufacturers of
1232-530: The Android system are required to either opt-out of Google Play Services or to obtain the Google apps package from either a device that has them pre-installed or an unofficial source. Proprietary software Proprietary software is a subset of non-free software , a term defined in contrast to free and open-source software ; non-commercial licenses such as CC BY-NC are not deemed proprietary, but are non-free. Proprietary software may either be closed-source software or source-available software . Until
1276-625: The Free Software Foundation. This includes software written only for Microsoft Windows, or software that could only run on Java , before it became free software. Most of the software is covered by copyright which, along with contract law , patents , and trade secrets , provides legal basis for its owner to establish exclusive rights. A software vendor delineates the specific terms of use in an end-user license agreement (EULA). The user may agree to this contract in writing, interactively on screen ( clickwrap ), or by opening
1320-416: The box containing the software ( shrink wrap licensing ). License agreements are usually not negotiable . Software patents grant exclusive rights to algorithms, software features, or other patentable subject matter , with coverage varying by jurisdiction. Vendors sometimes grant patent rights to the user in the license agreement. The source code for a piece of proprietary software is routinely handled as
1364-593: The company announced that the software was scanning 50 million apps per day. On November 6, 2019, Google announced the App Defense Alliance. Partners can request Google Play Protect to analyze an app. Results are sent to the partner and Google Play Protect receives results from partners. As of November, 2019, partners of the App Defense Alliance included ESET , Lookout and Zimperium . In October 2023, Google announced that Play Protect would scan sideloaded apps for malware at install time. Google Play Services

1408-498: The devices are not able to upgrade to the later operating system for a number of reasons. As a result, applications written for one version will not operate consistently on the other, and vice versa. In August 2010, developers of the OpenSignal wireless crowd-sourcing app detected 3,997 distinct values for "android.build.MODEL" among users of their app. This variable represents the device model, though it may be altered by adding
1452-447: The late 1960s, computers—especially large and expensive mainframe computers , machines in specially air-conditioned computer rooms—were usually leased to customers rather than sold . Service and all software available were usually supplied by manufacturers without separate charge until 1969. Computer vendors usually provided the source code for installed software to customers. Customers who developed software often made it available to
1496-619: The legal status of software copyright , especially for object code , was not clear until the 1983 appeals court ruling in Apple Computer, Inc. v. Franklin Computer Corp . According to Brewster Kahle the legal characteristic of software changed also due to the U.S. Copyright Act of 1976 . Starting in February 1983 IBM adopted an " object-code -only" model for a growing list of their software and stopped shipping much of
1540-491: The location technologies, providing geofencing APIs for scheduling specific actions when the user enters or leaves specific geographic boundaries, Fused Location Provider acquires location information such as reduced power usage and activity recognition for allowing applications to adapt to the current action of the user (e.g. cycling, walking, etc.). The Google Sign-in Android API provides single sign-on , authenticating
1584-490: The profitability of software development. Proprietary software generally creates greater commercial activity over free software, especially in regard to market revenues. Proprietary software is often sold with a license that gives the end user right to use the software. Fragmentation (programming) Fragmentation in a technology market happens when a market is composed of multiple highly-incompatible technologies or technology stacks , forcing prospective buyers of
1628-712: The public without charge. Closed source means computer programs whose source code is not published except to licensees. It is available to be modified only by the organization that developed it and those licensed to use the software. In 1969, IBM, which had antitrust lawsuits pending against it, led an industry change by starting to charge separately for mainframe software and services, by unbundling hardware and software. Bill Gates ' " Open Letter to Hobbyists " in 1976 decried computer hobbyists' rampant copyright infringement of software, particularly Microsoft's Altair BASIC interpreter, and asserted that their unauthorized use hindered his ability to produce quality software. But
1672-479: The services through common means. The package's services include location tracking and geofencing , single sign-on account services, user health and fitness tracking , payment processing, integrated advertising, and security scanning. Many apps on Android devices depend on the use of Google Play Services, and the package requires the user to use a Google Account and agree to Google's terms of service . Distributing Google Play Services on an Android device requires
1716-561: The software from becoming unsupported and unavailable abandonware . 3D Realms and id Software are famous for the practice of releasing closed source software into the open source . Some of those kinds are free-of-charge downloads ( freeware ), some are still commercially sold (e.g. Arx Fatalis ). More examples of formerly closed-source software in the List of commercial software with available source code and List of commercial video games with available source code . Proprietary software
1760-484: The software. This is particularly common with certain programming languages . For example, the bytecode for programs written in Java can be easily decompiled to somewhat usable code, and the source code for programs written in scripting languages such as PHP or JavaScript is available at run time . Proprietary software vendors can prohibit the users from sharing the software with others. Another unique license
1804-402: The source code available. Some licenses for proprietary software allow distributing changes to the source code, but only to others licensed for the product, and some of those modifications are eventually picked up by the vendor. Some governments fear that proprietary software may include defects or malicious features which would compromise sensitive information. In 2003 Microsoft established

1848-476: The source code is made available . Governments have also been accused of adding such malware to software themselves. According to documents released by Edward Snowden , the NSA has used covert partnerships with software companies to make commercial encryption software exploitable to eavesdropping, or to insert backdoors . Software vendors sometimes use obfuscated code to impede users who would reverse engineer
1892-606: The source code, even to licensees. In 1983, binary software became copyrightable in the United States as well by the Apple vs. Franklin law decision, before which only source code was copyrightable. Additionally, the growing availability of millions of computers based on the same microprocessor architecture created for the first time an unfragmented and big enough market for binary distributed software. Software distributions considered as proprietary may in fact incorporate
1936-928: The user inside applications using Google Account credentials. The Google Maps Android API allows applications to include Google Maps or Street View without the need to open a separate application, allowing full control over the camera and providing a means of adding custom markers and map overlays. The Google Drive Android API allows Google Drive to be used as a storage structure, providing lookup and syncing of documents along with other file manipulation tools. The Google Cast Android API adds casting functionality to allow Android applications to display content on TVs using Google Cast , additionally providing various helpers for common audio, video, and image types. Google Mobile Ads integrates advertisements into applications, allowing monetization by targeting ads based on factors such as user location. The Google Pay API allows purchases of services and goods via Google Pay . Other APIs include
