The KDE PIM community is committed to protecting the privacy of all users of its software. Sensitive information like user names and passwords is only used to perform the core functions of the software - receive and send emails and synchronize calendars and address books. The credentials and all user's personal information (including events, contacts, emails etc.) obtained from remote services (e.g. email servers) are only stored on the user's computer and are never shared with the developers of this software or any other third party. No user's personal information stored on the computer is ever shared with the developer or with any third party services unless the user manually does so, for example by copying or moving personal data (e.g. email) to a folder that is synchronized with the third party service.
However, some services that you decide to synchronize your personal data with may collect various information about your activity and interaction with the service - make sure to consult Privacy Policies or those services.
The objective of this policy document is to provide an open environment between developers and users of this software by openly stating what information the developer collects or not. This Policy applies to this software and the developers would not be held responsible for the content or privacy practices on any third-party software not operated by the developer to which this software links or that links to this software, therefore it is advisable to read up the Privacy Policies of third-party services that may be linked to this software.
Permissions and Access to third party services
Some user's personal information and data obtained from third party services are cached locally by a background service called Akonadi, which is part of Kontact. It is possible for any locally running software to interact with Akonadi and thus access, modify or delete any data stored there. The data are factically stored in a local database controlled by Akonadi. They may also be indexed for full-text search by Akonadi Indexing Agent.
Kontact provides optional integration with several Google services. Read below for a detailed explanation of what data Kontact and its components request from Google and what it does with those data.
Kontact and its components will use Google Sign-In in order to obtain access to content stored on a user's Google account (e.g. contacts, calendars, events. etc.). The information obtained from the Google Sign-In include user's real name, email address and picture and are stored locally on the user's computer to allow the user to more easily identify their Google account among other locally created accounts. Additionally, the Sign-In process provides the software with OAuth tokens which are used by the software to authenticate its requests to other Google services. The tokens are stored locally in KWallet.
Authenticating against Google and using the Akonadi Resources for Google Services means data are being exchanged with Google servers and Privacy Policies of Google and individual Google's services apply. Kontact makes sure that the exchanges with Google servers are securely encrypted and that only the data that the user has selected is exchanged with Google.
If the user does not add their Google account to Kontact, no information is exchanged with Google by Kontact at all.
Kontact and KOrganizer request full access to all calendars and events in those calendars from the user's Google Calendar in order to display them in user's calendar view in the applications and to allow the user to create, modify and delete events from the comfort of the aforementioned applications without having to go to the Google Calendar web interface. The list of calendars and events, including their entire content are cached locally on the user's computer using the Akonadi service described above. When the user creates a new event or modifies or deletes an existing event in one of the calendars synchronized from Google Calendar, the change will be propagated to Google Calendar immediately when the computer has internet connectivity. The software will never create, modify or delete content from the Google Calendar without previous user interaction, it may, however, download content from the Google Calendar in the background without user interaction if automatic synchronization is enabled.
Calendars and events synchronized from other services or local calendars are never exposed to user's Google Calendar account and shared with Google unless the user explicitly moves or copies them into the Google Calendar.
Kontact and KAddressbook request full access to all contacts from the user's Google account in order to display them in user's address book in the software and to allow the user to create, modify and delete contacts from the comfort of the aforementioned applications without having to go to the Google Contacts web interface. All contacts with all information are locally cached on the user's computer using the Akonadi service described above. When the user creates a new contact or modifies or deletes an existing contact synchronized from Google Contacts, the change will be propagated to Google Contacts immediately when the computer has internet connectivity. The software will never create, modify or delete content from the Google Contacts without previous user interaction, it may, however, download content from the Google Contacts in the background without user interaction if automatic synchronization is enabled.
Contacts synchronized from other services or local address books are never exposed to user's Google Contacts account or shared with Google unless the user explicitly moves or copies them into Google Contacts.
Kontact (through Storage Manager) and KIO GDrive (through Dolphin or other KIO-enabled application) request full access to user's Google Drive in order to allow the user to browse their Google Drive files from the comfort of the aforementioned software without having to go to the Google Drive web interface. Unless the user explicitly copies a folder or a file from Google Drive to their hard drive, all data remain stored only on Google Drive and are not cached or stored locally on the user's computer. The software will never access, create, modify or delete content from user's Google Drive account without user's interaction.
The contents of user's hard drive or other file-sharing services (e.g. NextCloud, Dropbox, etc.) are never exposed to the user's Google Drive or shared with Google unless the user explicitly copies them into the Google Drive.
Kontact and KMail request authentication to access user's Gmail account in order to display user's emails and email folders in the applications and allow the user to interact with them without having to go to the Gmail web interface. Email data are accessed through the IMAP protocol and they are cached on the user's computer using the Akonadi service described above. Depending on user configuration the cache may contain full emails including attachments (to allow user to read their email even when the computer does not have internet connectivity) or only headers. The software will never send emails on the user's behalf without user interaction nor will it modify or delete any emails without user's interaction. It may, however, download content from Gmail in the background without user interaction if automatic synchronization is enabled by the user.
Emails synchronized from other email providers or local email storage (e.g. maildir, mbox) are never exposed to the user's Gmail account or shared with Google unless the user explicitly moves or copies them into Gmail.
Kontact and other KDE PIM applications are developed in good faith and for general use. The developers will not be held accountable for how users decide to use this software and will not be liable for any losses and/or damages in connection with the use of the software.
