Evernote
Evernote is a note-taking and task-management application developed by the Evernote Corporation. It is intended for archiving and creating notes with embedded photos, audio, and saved web content. Notes are stored in virtual "notebooks" and can be tagged, annotated, edited, searched, and exported. Evernote is available on Android, iOS, macOS, Chrome OS (via Web), Microsoft Windows, as well as a web client. It offers free and paid plans for use. Architecture

Coding and versions 
In 2010, the programming language used to write Evernote's software was changed from C# for version 3.5 to C++ in version 4.0 to improve performance. Data entry 
In addition to keyboard input of typed notes, Evernote also supports image capture from cameras on supported devices and voice note recording. In some situations, text that appears in captured images can be recognized using OCR and annotated. Evernote also supports touch and tablet screens with handwriting recognition. Evernote web-clipping plugins are available for most popular Internet browsers and allow marked sections of webpages to be captured and clipped to Evernote. If no section of a webpage has been highlighted, Evernote can clip the full page. Evernote also supports the ability to e-mail notes to the service, allowing for automated note entry via e-mail rules or filters. Where suitable hardware is available, Evernote can automatically add geolocation tags to notes. As of November 2018, Evernote Pro integrates directly with Google Drive, Microsoft Outlook, Microsoft Teams, and Slack, and Evernote Pro adds an integration with Salesforce. All versions of Evernote also support integrations through IFTTT and Zapier. In 2013, Evernote deprecated its direct integration with Twitter in favor of these third-party services. Data storage and access 
On supported operating systems, Evernote allows users to store and edit notes on their local machine, using a SQLite database in Windows. Users with Internet access and an Evernote account can also have their notes automatically synchronized with a master copy held on Evernote's servers. This approach lets a user access and edit their data across multiple machines and operating system platforms, but still view, input, and edit data when an Internet connection is not available. However, notes stored on Evernote servers are not encrypted. Where Evernote client software is not available, online account holders can access their note archives via a web interface or through a media device. The service also allows selected files to be shared for viewing and editing by other users. The Evernote software can be downloaded and used as "stand-alone" software without using the online portion of an Evernote account (online registration is required for initial setup, however), but it will not be able to upload files to the Evernote server or use the server to synchronize or share files between different Evernote installations. Also, no image or Image-PDF (Premium only) recognition and indexing will take place if the software is used entirely offline. Accounts 

Evernote has various account options, including free and paid tiers. As of 2023, the paid tiers are named Personal and Professional. Previous Evernote tier names include Plus, Premium, and Business. Free, Personal, and Professional Evernote accounts have a maximum limit of 100,000 notes. Free users can create up to 250 notebooks while individual paid users have a notebook maximum of 1,000. As of 2023.10.26, free account users using web version have seen a pop-up window asking them to upgrade if their accounts exceed the limit: 1 notebook or 50 notes. People are frustrated and leaving for other note taking solutions. The app on iPhone still has no such limitation. Free accounts have a 60 MB upload limit each month. Personal accounts have a 1 GB monthly upload limit, and also include such features as offline notes on mobile devices and the ability to search texts within images. Accounts on the Professional tier have a 20 GB upload limit per month, can export notes as PDF files, and can forward emails directly into Evernote. The free service does not make files available offline on iOS and Android devices; while sometimes they are available from cache, editing these files can cause conflicts when synchronizing. In June 2016, Evernote announced the limitation for users of its free Basic account to two devices per year and raised prices for its premium service tiers. Non-paying Evernote users are able to sync notes between two devices. From early April 2018, Evernote Plus was no longer available for purchase; However, users who currently have the Plus subscription can maintain it as long as their subscription is still active. Supported platforms 

Evernote clients are available for Android, iOS (iPad, iPhone, and iPod Touch), macOS, Microsoft Windows, and Web. Additionally, portable versions of Evernote are available for flash drives and U3 drives. There are no officially supported native clients for BSD or Linux, but the company provides an API for external Linux clients. There is substantial variation in supported features on different platforms. For example, it is possible to edit Rich Text Format and sketches on Windows, while on Apple Macintosh it is possible to edit rich text, but only view sketches. Web clipping support is installed by default on the Internet Explorer and Safari browsers when the Evernote software is installed on Windows or macOS. Evernote web-clipping plugins are available for the Firefox, Google Chrome, Opera, and Yandex browsers. The Evernote email-clipper is automatically installed in Microsoft Office Outlook if the desktop version is installed on the same computer. There is also a Thunderbird email plugin. Apps and tools

Data loss 
The service has experienced several cases of losing customer data. Denial-of-service attacks 
On June 11, 2014, Evernote suffered a distributed denial-of-service attack that prevented customers from accessing their information. The attackers demanded a ransom, which Evernote refused to pay. A denial-of-service attack on August 8, 2014, resulted in a brief period of downtime for evernote.com; service was quickly restored. Security breach 
On March 2, 2013, Evernote revealed that hackers gained access to their network and accessed user information, including usernames, email addresses, and hashed passwords. All users were asked to reset their passwords. In the wake of this, Evernote accelerated plans to implement an optional two-factor authentication for all users. Privacy controversy 
In December 2016, Evernote announced its privacy policy would be changing in January 2017, leading to claims the policy allowed employees of the firm to access users' content in some situations. In response to the concerns, Evernote apologized and announced the policy would not be implemented, and that its employees would not have access to users' content unless users opted in. Evernote v10 controversy 
In late 2020, Evernote released Evernote v10, written from scratch in the Electron framework, to replace older versions on multiple platforms. Some users noted the new app was much slower than the previous Windows and iOS versions, had  many features removed, and did not work with some default keyboard layouts, including Turkish, Latvian, and Polish, due to a conflict of hardcoded key bindings.
