Adds confidentiality markers to Gmail emails. Confidential Email Watermarker is a privacy-focused Chrome extension that helps users add a clear confidential watermark overlay while viewing or composing sensitive email content in the browser. It is designed for professionals, teams, consultants, legal workers, finance users, founders, managers, administrators, and anyone who regularly handles private or internal information through web-based email. The extension provides a simple visual reminder that an email contains confidential material, helping reduce accidental sharing, screenshots, misrouting, or careless handling of sensitive communication. Please note this extension only works when you're on the Gmail domain. Email is one of the most common places where confidential information appears. A single message may contain client details, internal plans, financial figures, legal notes, account information, employee discussions, project updates, private attachments, or strategic decisions. When messages are opened in a busy browser window, it can be easy to forget how sensitive the content is. Confidential Email Watermarker helps by adding a visible watermark layer that reminds the user and anyone nearby that the information should be treated carefully. The extension is especially useful for people who work with confidential email during meetings, screen sharing, presentations, or collaborative review sessions. When an email is displayed on screen, the watermark can make the sensitivity of the content more obvious. This can help prevent situations where private information is accidentally shown to the wrong audience. It can also support better internal habits by making confidentiality visible instead of relying only on memory or subject-line labels. Confidential Email Watermarker works directly inside Chrome and does not use any external API. No data is ever transmitted to third-party servers. The watermark effect is applied locally in your browser using browser-based functionality. The extension does not upload email content, scan message text remotely, send subject lines to outside services, collect email addresses, transmit attachments, or share browsing activity. Everything happens on your own device, giving users a safer and more private way to add visual confidentiality cues. Privacy is central to the extension’s purpose. A tool designed for confidential email should not create a new privacy risk. Confidential Email Watermarker is built so it does not need cloud processing, remote storage, analytics services, online accounts, or third-party integrations to perform its core function. It does not send your private messages anywhere. Whether you are reviewing personal email, company email, client communication, legal correspondence, HR discussions, or internal strategy updates, the watermarking process remains local inside Chrome. Using the extension is straightforward. After installing it, you can activate the watermark from the Chrome toolbar when viewing sensitive email content. The extension can place a repeated or prominent “Confidential” style overlay on the page, making it clear that the content should be handled with care. When the watermark is no longer needed, you can turn it off and return the page to its normal appearance. The goal is to provide a quick, simple visual safeguard without complicated setup. The extension can be helpful for professionals in many roles. Consultants can use it when reviewing client emails or presenting project updates. Lawyers and legal teams can use it when handling privileged or sensitive correspondence. Finance teams can use it when viewing budget discussions, invoices, financial projections, or transaction details. Human resources teams can use it while reviewing employee-related messages. Executives and founders can use it when discussing strategy, hiring, fundraising, partnerships, or internal decisions. Confidential Email Watermarker can also support remote work habits. Many people now work from home, shared spaces, coworking offices, cafés, airports, and client locations. In these environments, shoulder surfing and accidental screen exposure can be concerns. A visible watermark cannot replace secure behavior, but it can act as a strong reminder that the content on screen deserves extra care. It encourages users to think before sharing their screen, taking screenshots, forwarding messages, or leaving a window open. The extension is also useful during screen recording and online meetings. If you need to briefly show an email while explaining a workflow or issue, the watermark can signal that the content is sensitive. It can help viewers understand that the information should not be copied, shared, or redistributed without permission. For internal teams, this can reinforce privacy expectations and create a more careful communication culture. Because the extension does not use external APIs, it remains lightweight and responsive. There is no waiting for a server to process email content, no upload step, no login requirement, and no dependency on a third-party service. The watermark can be applied locally and quickly whenever needed. This focused design keeps the extension simple, practical, and privacy-friendly. Confidential Email Watermarker is not intended to replace proper security systems, access controls, encryption, legal review, or company data protection policies. Instead, it provides a useful visual layer that can complement responsible information handling. A watermark can help remind users that certain messages require caution, but users should still follow their organization’s policies for confidential communication, secure sharing, and data protection. The extension is ideal for users who want a simple browser-based way to make sensitive email content more visibly protected. It can help reduce careless exposure by making confidentiality obvious at the moment the content is being viewed. It is especially helpful for people who frequently switch between many emails, tabs, tools, and meetings throughout the day. No external API is used. No data is ever transmitted to third-party servers. No email content, subject lines, recipients, attachments, browsing history, or personal information is uploaded or shared. The watermarking effect runs locally inside Chrome, keeping your confidential communication on your own device. With its clear purpose, easy activation, local processing, and privacy-first design, Confidential Email Watermarker is a practical Chrome extension for anyone who handles sensitive email. It adds an immediate visual confidentiality reminder while keeping your data private, secure, and under your control.
