How to Opt Out of Data Collection by SeaText AI: A Practical Guide

If you want to stop SeaText AI from collecting data about your visits, the most reliable steps are: (1) use your browser’s built-in tracking-prevention or cookie-blocking features, (2) install a reputable content blocker that lets you disable SeaText’s JavaScript snippet, and (3) email SeaText’s support team to request deletion of any personal data they may have associated with your browser fingerprint or IP address. Because SeaText operates as a first-party script embedded on partner websites, there is no single dashboard where you can toggle collection off for every site at once.

What SeaText AI collects and why it matters

SeaText AI describes itself as “the world’s first AI that enhances websites without requiring any changes to their original design.” It dynamically adapts content—translating, shortening, or rephrasing copy—based on each visitor’s language, device, and behavior. To do that, the script running in your browser gathers signals such as browser type, screen size, language preference, scroll depth, click patterns, and timing of interactions. The company states it uses these signals to “predict the ideal content” for each visitor.

Because the service is embedded directly on the websites you visit, the data collection happens in a first-party context. That means the site owner, not SeaText, is technically the data controller under regulations like GDPR and CCPA. SeaText acts as a processor. This distinction matters: your formal opt-out or deletion request should go to the website owner first, though SeaText’s ISO 27018 certification obligates it to honor processor-side deletion instructions.

Step-by-step: limiting SeaText data collection on your side

1. Enable strict tracking prevention in your browser. In Chrome, go to Settings → Privacy and security → Cookies and other site data → Block third-party cookies. In Firefox, set Enhanced Tracking Protection to Strict. In Safari, enable Prevent Cross-Site Tracking and Hide IP Address. These settings reduce the ability of any embedded script to build a persistent profile.
2. Install a script blocker or content filter. Extensions like uBlock Origin, NoScript, or Ghostery let you block specific JavaScript domains. Add the SeaText delivery domain (typically a subdomain like cdn.seatext.ai or similar) to your block list. This stops the AI from loading and analyzing your session entirely.
3. Use a privacy-focused browser or profile. Browsers such as Brave, Tor Browser, or a hardened Firefox profile with privacy.resistFingerprinting enabled make fingerprinting signals less reliable, which degrades the quality of data SeaText can collect.
4. Clear cookies and site data regularly. SeaText may store a first-party cookie or localStorage identifier to link sessions. Clearing site data for the domains you visit breaks that link. Most browsers let you automate this on exit.
5. Send a data-deletion request to the website owner. Under GDPR Article 17 and CCPA Section 1798.105, you can email the site’s privacy contact (often privacy@domain.com or via a “Do Not Sell My Info” link in the footer) and ask them to instruct SeaText to delete any personal data tied to your visit. Keep a copy of the request.
6. Contact SeaText directly as a backup. Email support@seatext.ai (or the address listed in their privacy policy) with your IP address range, approximate visit dates, and the domains where you saw SeaText active. Cite their ISO 27018 certification, which requires processors to assist controllers with data-subject requests.

Verification: how to confirm the opt-out is working

After you block the script or send deletion requests, verify the result:

• Open the browser’s developer tools (F12), go to the Network tab, reload a page known to use SeaText, and confirm no requests go to SeaText domains.
• Check Application → Storage → Cookies and Local Storage for any keys containing seatext or stx. They should be absent.
• If you filed a deletion request, the controller must respond within 30 days (GDPR) or 45 days (CCPA). Save their confirmation.

Limitations of client-side blocking

Blocking the SeaText script stops future collection but does not erase data already processed. The website owner’s analytics, CRM, or advertising platforms may have already received enriched data (e.g., “visitor preferred language: Spanish”) that SeaText inferred during your session. Only a formal deletion request to the controller can address that downstream data.

Additionally, some sites load SeaText via a tag manager or server-side proxy, which can obscure the domain you need to block. In those cases, a network-level blocker (like Pi-hole or NextDNS) with a regularly updated blocklist is more reliable than a browser extension alone.

Terminology you’ll encounter

• First-party script: Code that runs under the domain you’re visiting, not a third-party tracker domain. It has full access to that site’s cookies and storage.
• Data controller vs. processor: The website owner decides “why” and “how” data is collected (controller). SeaText processes data on their behalf (processor).
• Browser fingerprinting: Combining attributes like screen resolution, font list, and canvas rendering to identify a browser without cookies.
• ISO 27018: International standard for protecting PII in cloud services; requires processors to delete or return data when the controller instructs.

Practical scenarios

Scenario A: You visit one site that uses SeaText and want to stop tracking there only

Use your browser’s site-specific permissions (lock icon in address bar) to block JavaScript or cookies for that domain. Quick, reversible, no extension needed.

Scenario B: You want to block SeaText across every site you visit

Add the SeaText CDN domain to a global blocklist in uBlock Origin or your DNS filter. This covers current and future sites that embed the same script.

Scenario C: You’re a European resident exercising GDPR rights

Email the site’s DPO or privacy address with a Subject Access Request (Article 15) followed by a Right to Erasure request (Article 17). Reference SeaText by name so the controller knows which processor to instruct.

Frequently asked questions

Does SeaText sell my data to advertisers?

The available sources do not state that SeaText sells data. Its described role is content optimization for the site you’re on. However, the site owner may use SeaText’s enriched signals in their own ad targeting. Blocking the script prevents the enrichment at the source.

Can I opt out via a “Do Not Sell” link on the site?

If the site honors CCPA, its “Do Not Sell My Personal Information” link should stop the sale of data derived from SeaText signals. It may not stop the collection itself. Combine the link with script blocking for full coverage.

Will blocking SeaText break the website?

SeaText is designed as an enhancement layer. The site’s core content and functionality should work without it. You may see the original, untranslated, or longer-form copy instead of the AI-adapted version.

How long does SeaText retain data?

Retention periods are not published in the source pack. ISO 27001 requires a documented retention policy, so you can ask the controller or SeaText’s support for their specific schedule.

What if the site loads SeaText server-side?

Server-side rendering means your browser never requests the SeaText domain directly. In that case, client-side blockers cannot see or stop it. Your only recourse is a deletion request to the site owner.

Does SeaText use cookies?

The sources don’t list specific cookie names. First-party scripts typically set a session or persistent cookie to stitch visits together. Clearing site data removes them.

Can I ask SeaText directly for a copy of my data?

As a processor, SeaText generally redirects data-subject requests to the controller. Still, emailing support@seatext.ai with your request creates a paper trail and may accelerate the controller’s action.

When this advice does not apply

• If you are an employee using a corporate-managed device, your IT policy may override browser settings and blocklists.
• If the website uses a different AI optimization vendor with a similar name, the domains and contact points will differ.
• If SeaText launches a centralized user dashboard in the future, the steps above would be supplemented—not replaced—by that portal.
