Privacy Policy for Downloader for Instagram – Promaster
This Privacy Policy describes how Downloader for Instagram – Promaster (the “extension”) processes information during its operation. The extension is a browser-based tool designed to perform user-initiated actions on supported websites. Certain technical data may be processed as a natural consequence of providing these services. By installing or using the extension, users acknowledge and accept the data practices described herein.
The extension does not request, require, or intentionally collect personal identifiers such as names, email addresses, account credentials, passwords, or similar information capable of identifying an individual. Personal information is processed only when a user voluntarily submits such data for support or communication purposes, and in such cases it is used exclusively to respond to the request and for no other purpose.
During normal operation, the extension may process technical information generated through interaction between the browser, the extension, and external web platforms. This may include network-related signals, browser and operating system characteristics, session diagnostics, and events triggered by user actions. Such data is processed solely to ensure correct functionality, compatibility, security, prevention of misuse, and general reliability of the extension. This information is not used to identify users and is not employed for profiling or tracking purposes.
Certain online platforms require authentication through session cookies in order to access or interact with content. Where applicable, the extension may rely on such cookies locally within the user’s browser environment to perform actions explicitly initiated by the user. These cookies remain entirely on the user’s device and are neither transmitted to, stored by, nor analyzed on external servers controlled by the extension. Their use is limited strictly to functional necessity and remains confined to the local browsing context.
The extension may process non-identifiable information related to its internal performance and usage in an aggregated form. This processing is intended to support maintenance, improve stability, and refine functionality over time. Such information cannot be linked to individual users. Where optional analytics are involved, users may disable them through the extension settings, after which only essential processing required for operation remains active.
Upon initial activation, the extension generates a randomly created anonymous identifier. This identifier is not derived from personal data, device identifiers, browser fingerprints, or hardware attributes. It is used solely to distinguish anonymous usage sessions and may be transmitted to a server exclusively for the purpose of counting unique installations or usage events. The identifier cannot be used to identify, track, or profile any user.
Information may be processed when the extension is loaded, when its interface is accessed, when content-related actions are initiated, or when internal components communicate with backend services required for functionality. All processing activities are strictly limited to what is necessary to perform the operations explicitly requested by the user and do not extend beyond these purposes.
To support ongoing development and provide the extension free of charge, promotional content or references to partner services may be displayed. Such promotional activities are not connected to personal data and do not involve the sale or sharing of browsing history or user-specific behavioral information. Promotional content may appear on various websites; however, the extension does not insert advertisements into search engine results pages, including those of Google, Bing, or Yahoo.
The extension includes a monetization mechanism that may be activated on certain commercial websites. In such cases, promotional content may be displayed in separate browser tabs. This mechanism does not alter website content or interfere with normal browsing.
Users can disable promotional content at any time through the extension settings.
The extension may contain links to or references to third-party websites or services that operate under their own privacy policies. Responsibility for the data practices of such third parties lies solely with them. Limited technical information may be shared with infrastructure or service providers strictly when necessary to operate or maintain the extension, subject to confidentiality obligations. Information may also be disclosed when required by applicable law or legal process.
Information processed by the extension is retained only for the minimum period necessary to fulfill operational and technical requirements. Once the information is no longer required for these purposes, it is removed in accordance with internal retention practices.
The extension is not intended for use by individuals under the age of 13, and no information is knowingly collected from such users.
Single Purpose
The extension is designed to provide extended functionality related to interacting with and processing content from instagram.com. All permissions requested are strictly limited to enabling features directly associated with this purpose and are not used for unrelated activities.
Storage
The storage permission is used to save user preferences and configuration settings locally within the browser. This allows the extension to remember user choices, such as feature toggles or interface options, across sessions without requiring repeated setup.
Tabs
The extension uses the chrome.tabs.get() and chrome.tabs.query() APIs with access to the url property to determine whether certain features should be enabled for the currently active tab. This permission is required to detect supported pages and ensure that extension functionality is applied only when relevant.
Cookies
The cookies permission is used solely to check whether the user is authenticated on instagram.com. Cookie data is accessed locally within the browser and is never transmitted, stored externally, or used for tracking or identification purposes.
WebRequest
The extension uses webRequest to modify specific request headers when necessary for proper functionality. This is required to ensure compatibility with Instagram’s content delivery mechanisms and to allow media resources to be accessed correctly for user-initiated actions.
Downloads
The downloads permission allows the extension to use the chrome.downloads API to save media files directly to the user’s device. This permission is essential for enabling users to download images and videos in response to explicit actions they initiate.
Host Permissions (://.instagram.com/*)
Access to ://.instagram.com/* is required to interact with Instagram pages and media resources. This permission enables the extension to detect, process, and download embedded images and videos, including cases where Instagram content is displayed or embedded on third-party websites. The extension interacts only with pages where such content is present and does not access unrelated websites.
In the event of a data-related incident that may affect users, notification will be provided through the extension within seven business days. Users with questions regarding this Privacy Policy or the extension’s data practices may contact support through the interface provided within the extension.
