Ultimate Video Enhancer

Privacy Policy

Last updated: August 2026

Who we are

Ultimate Video Enhancer ("UVE") is published under the Systemaweb product brand. Customer support and billing correspondence for UVE are handled via NestSyncFlow at sales@nestsyncflow.com. This policy describes how the UVE browser extension and the website at systemaweb.com process information.

By installing UVE or using systemaweb.com, you agree to this policy. If you do not agree, do not use the extension or the site.

Summary

  • Core playback features run locally in your browser.
  • We do not sell your personal data.
  • The extension does not include advertising or usage-analytics SDKs.
  • Some optional features send limited data only when you use them (license, subtitles, dislike counts).
  • Purchases are processed by Stripe.

Extension — local storage

Speed, volume, templates, theme, optional OpenSubtitles API key, and license status are saved in browser extension storage on your device. Local subtitle files (.vtt / .srt) are processed in the current browser session and are not uploaded to Systemaweb servers by default.

UVE requests access to websites so it can enhance HTML5 media on the page you are watching. That permission is used for playback control (speed, volume, captions). It is not used to build or sell a browsing history profile.

Optional network requests (extension)

  • License validation — when you activate Pro, your license key is sent to systemaweb.com to confirm status. The response may include an email associated with the purchase; that email may be stored locally in the extension for display.
  • OpenSubtitles — when you use Pro subtitle search, UVE sends the video title shown on the page and your OpenSubtitles API key to OpenSubtitles so matching files can be returned.
  • Return YouTube Dislike — if you enable the optional dislike feature, the YouTube video ID is sent to the Return YouTube Dislike API.
  • Caption fetch — when applying certain caption sources, the extension may fetch caption file bytes from the media host (or via the extension background script) to display them in UVE.

Website

systemaweb.com may use privacy-friendly analytics (Plausible) that does not use advertising cookies and does not track you across unrelated sites. Analytics help us understand which pages and install buttons are used — not which videos you watch inside the extension.

If you join a waitlist, we process the email address you submit only to notify you about related product availability, unless a different purpose is stated on the form.

Student pricing may require a school or university email so we can verify eligibility. That email is used for verification and checkout association, not for unrelated marketing lists.

Purchases (Stripe)

UVE Pro is sold as an optional upgrade on systemaweb.com. Payments are processed by Stripe. Stripe receives the payment details and billing information needed to complete the purchase. After payment, we generate a license key, may email it to the address used at checkout, and store license metadata needed to validate activation and handle support or refunds.

Retention & requests

Purchase and license records are kept as long as needed to provide the product, prevent abuse, meet legal obligations, and handle refunds or support. See also our refund policy. Website analytics are retained according to the analytics provider’s settings.

To ask about waitlist removal, license email resend, or purchase-related questions, contact sales@nestsyncflow.com. We may need enough information to verify the request (for example the purchase email).

Security

We use reasonable technical and organizational measures appropriate to a small software product (HTTPS, server-side secrets for license signing, payment processing via Stripe). No method of transmission or storage is completely secure.

Children

UVE is not directed at children under 16. Do not submit personal information for children through our forms.

International use

The service may be accessed from different countries. Information may be processed in the EU/EEA or other regions where our providers (for example Stripe, hosting, email delivery) operate.

Changes

We may update this policy from time to time. The "Last updated" date will change when we do. Continued use after an update means you accept the revised policy.

Limitation of claims

To the maximum extent permitted by applicable law, UVE and related sites are provided "as is" without warranties of any kind. We are not liable for indirect, incidental, special, consequential, or punitive damages, or for loss of data, profits, or business interruption arising from use of the extension or website. Mandatory consumer rights in your country of residence are not affected where they cannot be waived.
