Terms of Service

These Terms of Service (the "Terms") govern your use of the Download SIU desktop application and the downloadsiu.com website. By downloading, installing, activating, or using the App, you agree to these Terms. If you do not agree, do not use the App.

1. The Service

Download SIU is a desktop application for personal computers that allows you to download video and audio content from publicly accessible sources on the internet, process it locally on your own machine (using the embedded open-source tools yt-dlp and FFmpeg), and save it to a folder of your choice. The App is built with Electron and protected by a custom security system that encrypts and integrity-checks its own program files.

2. Eligibility

You must be 18 years of age or older to use the App or purchase a plan. By using the service you declare that you meet this requirement.

3. License Plans and Activation

We offer paid plans (monthly, annual, and lifetime), as described on our Plans page.
We also offer a free 5-day trial, activated from a button inside the App. It requires no account, no email and no payment card: the App sends only your computer's hardware code. Each computer may activate the trial once, after which a paid plan is required.
Each purchase generates one unique, non-transferable license code, delivered instantly to your email.
Each license may be activated on one (1) computer only. The license is bound to that computer's hardware identifier. A code already activated on another PC cannot be reused.
You are responsible for keeping your license code confidential. Do not share it with anyone.

Your time is always respected. If you purchase a plan while your current license still has active time, the new time is added on top of your remaining time — both the expiration date and the remaining time are calculated in your favor. We never reduce the time you have already paid for.

4. Payments

Prices are shown in US dollars on the Plans page and are processed securely by Stripe.
We never see or store your card details (see our Privacy Policy above).
Your license code is delivered by email immediately after Stripe confirms your payment.

5. Refund Policy

Because licenses are digital goods delivered instantly by email, refund requests are reviewed on a case-by-case basis, at our sole discretion. If you experience a genuine problem — for example, a payment completed without receiving your license, or a technical issue that we cannot resolve — write to us through the Contact page and we will review your case individually and fairly.

6. Acceptable Use and Copyright

The App is a neutral tool. You are solely responsible for the content you choose to download and for complying with the laws of your country and the terms of the websites you download from.
Only download content that you have the legal right to download and store: your own content, content in the public domain, content with a license that permits downloading, or content for which you have the rights holder's permission.
You may not use the App to infringe copyright, to illegally distribute protected content, or to circumvent technological protection measures where prohibited by law.
We do not host, store, provide, or have any knowledge of the content you download — all downloads happen directly between your computer and the source site.

7. Prohibited Conduct

Sharing, reselling, or publishing your license code.
Attempting to activate one license on multiple computers.
Reverse-engineering, decompiling, bypassing, or attacking the App's security system, the license system, or our servers.
Using the App for any unlawful purpose.

Violation of these rules may result in license revocation without refund, and where appropriate, legal action.

8. Software Security System and Your Files

To protect the App from tampering and piracy, its program files are encrypted and verified at runtime. If the security system detects manipulation of the App itself, it may refuse to run and may delete only the App's own protected and temporary working files. The security system never deletes, modifies, reads, or uploads your personal files, downloads, or documents.

9. Updates

The App can automatically check downloadsiu.com for new versions. Updates may add features, fix bugs, or adjust how the App works. Continuing to use the App after an update means you accept these Terms as they read at that time.

10. Disclaimer of Warranties

The App is provided "as is" and "as available", without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, or uninterrupted operation. Third-party websites change constantly, and we do not guarantee that downloading will work on every site at all times.

11. Limitation of Liability

To the maximum extent permitted by law, we shall not be liable for any indirect, incidental, special, or consequential damages — including lost profits, lost data, or claims by third parties — arising from your use or inability to use the App. Our total liability shall never exceed the amount you actually paid for your current plan.

12. Indemnification

You agree to indemnify and hold us harmless from any claim, damage, or expense arising from your misuse of the App, your violation of these Terms, or your infringement of any third party's rights (including copyright).

13. Governing Law

These Terms are governed by the laws of the State of Florida, United States, and applicable U.S. federal law, without regard to conflict-of-law principles. Any dispute arising from these Terms or the service shall be brought exclusively in the state or federal courts located in Miami-Dade County, Florida, and you consent to their jurisdiction. Nothing in these Terms limits any mandatory consumer rights you may have under the laws of your country of residence.

14. Changes to These Terms

We may update these Terms at any time. The version published on this page, with its "Last updated" date, is the one in force. Continued use of the App after a change constitutes acceptance.

15. Termination

You may stop using the App at any time. We may suspend or revoke a license that breaks these Terms (see Section 7). Provisions that by their nature should survive termination — disclaimers, limitation of liability, indemnification and governing law — remain in effect.

16. Copyright Complaints

Download SIU is a neutral tool and does not publish or host a catalog of content. If you are a rights holder and believe the App, or a file our server prepared temporarily for a user, infringes your copyright, send a written notice through the contact page (subject “Something else”, mentioning “Copyright notice”) with: (a) identification of the work; (b) where the material is; (c) your name and contact details; (d) a statement that you believe in good faith that the use is not authorized; and (e) a statement, under penalty of perjury, that the notice is accurate and that you are the rights holder or authorized to act for them. We review each notice and may block the source concerned or revoke the licenses of repeat infringers.

17. General

These Terms and the Privacy Policy are the entire agreement between you and us about the App and the Site. If any part is found unenforceable, the rest stays in effect. If we do not enforce a right, that is not a waiver of it. Licenses are personal and non-transferable. You agree that we may send you notices and service messages by email, and that this satisfies any legal requirement for written notice.
