Terms of Sale and Licence Agreement

1. Who we are

VSKA Vanguard is made and sold by Vincentius Surya Kurnia Adi, trading as VSKA, 9F-7, No. 1643, Jiancheng Road, South District, Taichung 402, Taiwan (“we”, “us”).
Contact: vska@live.com.

2. Who processes your order

Our order process is conducted by our online reseller Lemon Squeezy. Lemon Squeezy is the merchant of record for all our orders: it takes the payment, charges and pays the sales tax or VAT, issues your invoice, and handles refunds and payment disputes. Lemon Squeezy's own terms also apply to your purchase.

3. What you buy

• A licence for one PC for one year. The price is shown on vska.live/vanguard and at checkout (US$39 per PC per year, plus tax where it applies).
• Licence key: after payment you receive a licence key by email. You enter it in the program (Settings, Licence tab) on the PC you want to protect.
• Several PCs: one key works on one PC at a time. For several PCs, buy one licence per PC. To move a licence to another PC, use “Remove from this PC” first.
• Automatic renewal: the licence renews every year at the price shown at checkout. You can cancel at any time through the link in your purchase email (Lemon Squeezy's customer portal). After you cancel, the licence runs until the end of the year you have paid for.

4. Free trial

• You can use the program free for 30 days before you buy. No payment details are needed for the trial.

5. What happens when a licence ends

• Protection keeps working. The firewall rules, blocked addresses and your allow list stay in place in every case, so the program never leaves your PC less protected or locks you out.
• What stops: after the trial or a licence ends, program updates, country-list refreshes and alerts stop until you buy or renew.

6. Refunds

See our Refund Policy (vska.live/refund): a full refund within 14 days, no questions asked.

7. Licence to use the software

• What you may do: we grant you a non-exclusive, non-transferable right to install and use VSKA Vanguard on one PC per licence, for the licence period, to protect computers you own or are authorised to manage.
• What you may not do: sell, rent or sublicense the software, or share your licence key. You may not remove the licence check, or reverse engineer the software except where the law allows it.
• Ownership: the software stays our property. Third-party parts keep their own licences (listed in THIRD-PARTY-NOTICES.md, installed with the program).

8. Your responsibilities

• Your network: VSKA Vanguard changes the Windows Firewall settings for Remote Desktop on your PC. You are responsible for choosing settings that fit your network, and for keeping another way to reach the PC (for example local access) while you change them.
• Backups: keep backups of important data. No security product can stop every attack.

9. Warranty and liability

• “As is”: the software is provided as is. We will fix reported faults with reasonable effort, but we don't promise that it is error-free or stops every attack.
• Limit: as far as the law allows, our total liability for any claim is limited to the amount you paid for the licence in the 12 months before the claim. We are not liable for indirect losses, such as lost data, lost profit or business interruption.
• Your legal rights: nothing in these terms limits rights you have under consumer protection law that cannot be excluded.

10. Privacy

See our Privacy Policy (vska.live/privacy).

11. Changes

We may update these terms. The version in force on the day of your purchase or renewal applies to that purchase or renewal.

12. Law

These terms are governed by the laws of Taiwan (Republic of China). The Taiwan Taichung District Court is the court of first instance, without limiting any right you have to go to court where you live.
