Terms of Use and Acceptable Use
Effective date: 10 September 2026. Privacy Policy: sentcue.com/privacy.
1. Agreement
By installing or using Email Tracking, a Chrome extension hosted by SentCue, you agree to these Terms. If you do not agree, do not install or use the extension. These Terms include the Privacy Policy.
2. The service
Email Tracking is a Chrome extension for Gmail on the web. It may add a tracking image to messages you choose to track and show activity signals in Sent. A signal is not proof of reading, delivery, or that a particular person opened the message. We do not provide email transport; Gmail still sends the mail.
The current version (1.2) does not require an Email Tracking or SentCue account, does not use the Gmail API or Google OAuth, and does not support Scheduled Send, Outlook, or the Gmail mobile apps.
You turn tracking on in the toolbar popup after the disclosure. You can also turn tracking on or off for one message in Gmail compose. Global Off always wins: if activity detection is off in the popup, no message is tracked. After you send a tracked message, Recent and History stay on this Chrome install. History can include local reminders. Desktop notifications are optional and need a separate Chrome permission.
Later paid or free features (for example cloud history, a SentCue account, Google OAuth, or link tracking) are not part of this version. If we add them, these Terms and the Privacy Policy will be updated first.
3. Not affiliated with Google
SentCue is independent and is not affiliated with, endorsed by, or sponsored by Google LLC. “Gmail” and “Google” are trademarks of Google. We mention Gmail only to describe where the extension runs.
4. Email tracking — your role as controller
When you turn tracking On, you act as the data controller (or equivalent) for personal data relating to your recipients. SentCue acts as a technical processor for token, timestamps, and coarse client class, only to provide the feature. You instruct us to process that data by enabling tracking after the disclosure.
You are solely responsible for complying with privacy, ePrivacy, employment, marketing, and communications laws that apply to your messages. Requirements vary by jurisdiction and context and may include informing recipients, obtaining consent before using a tracking pixel, and answering access or deletion requests. The disclosure you accept in the extension records your choice to enable the feature; it is not consent from a recipient. We do not automatically disable tracking for any region, and we cannot fulfil recipient rights requests in the sender’s place.
5. Acceptable Use Policy
You may not use Email Tracking to:
- stalk, harass, or covertly surveil a person;
- monitor children;
- covertly monitor employees or other people without a lawful basis and any required notice;
- use tracking as a surveillance tool on medical or similarly sensitive communications;
- run bulk unsolicited outreach whose purpose is hidden tracking;
- attempt to access another user’s install, tokens, or our systems without authorization;
- interfere with or reverse-engineer the service in a way that harms others or evades the kill switch.
We may disable tracking globally (kill switch) or refuse support if we reasonably believe these rules are broken.
6. Your other responsibilities
- Keep your Chrome install and Gmail account under your control.
- Do not upload or send unlawful content through Gmail while using the extension.
- Understand that scanners, proxies, and self-opens can create or hide signals.
7. No warranty
THE SERVICE IS PROVIDED “AS IS”. We do not warrant that signals are complete, accurate, timely, or that they correspond to a human read. Nothing here is legal, employment, or deliverability advice.
8. Limitation of liability
To the maximum extent permitted by law, SentCue and its operator are not liable for lost business, follow-up decisions based on signals, or indirect or consequential damages. Nothing excludes liability that cannot be excluded (including fraud or liability that mandatory consumer law preserves). Our total liability for a claim relating to the free v1 service shall not exceed USD 100.
9. Intellectual property
The extension, site, and SentCue name are owned by the operator. You keep rights in your own email content. We do not claim ownership of Gmail or of messages you send.
10. Changes and termination
We may change these Terms; the effective date will update. We may withdraw the service or the kill switch. You may stop using Email Tracking by turning tracking Off, deleting install data (this also clears local history and reminders on this device), and uninstalling the extension.
11. Governing law
These Terms are governed by applicable law, excluding conflict-of-law rules. The operator is the operator of Email Tracking. Disputes shall be brought before the competent courts of the jurisdiction where the operator is established or legally resident, unless mandatory consumer protection laws in your country provide otherwise.
