Terms of Sale and License Agreement (EULA)

1. Who we are

Visor is developed and sold by Tetono, Thailand (“we”, “us”). You can reach us at [email protected].

“Software” means the Visor program, its installer, updates and documentation. “License key” means the code used to activate Visor Pro.

2. Accepting these terms

By downloading, installing, using or buying Visor, you agree to these terms. If you don't agree, please don't install or use the software. If you use it on behalf of a company or organization, you confirm that you are authorized to accept these terms for it.

3. Free edition license

We grant you a non-exclusive, non-transferable license to install and use the Visor free edition at no cost, for personal or business use. The free edition shows no ads, installs no other software and collects no usage data.

You are welcome to recommend Visor or share the download link https://visor.tetono.com/en/download/. Please don't re-host or redistribute the installer elsewhere without our written permission, so that people always get the genuine, safe file.

4. Buying Visor Pro

• Price: on the English site, Visor Pro is shown at US$2.99, paid once (the Thai site shows the Thai-baht price, THB 79). There is no subscription and nothing renews automatically. The price that applies is the one shown at checkout when you buy.
• Currency: Charged in US dollars on the English site. Your bank or card issuer may also apply its own exchange rate or foreign-transaction fees, which are outside our control.
• Taxes: taxes such as VAT, GST or sales tax may apply where required by law. When they do, they are calculated and shown at checkout.
• Payment: through Stripe's checkout page. On the English site you can pay by credit or debit card, Apple Pay or Google Pay. Stripe processes the payment; we never see or store your full card number.
• The contract is formed when your payment succeeds and a license key is issued to you.
• Receipts: Stripe may send a receipt to the email address you enter at checkout. If you need other documents, contact [email protected].

5. Key delivery and activation

• Your license key appears on the thank-you page as soon as your payment succeeds, and is also emailed to you once our email delivery is in place.
• If you lose your key, request it again on the key recovery page or email support.
• If you buy from inside the app, Visor Pro activates on that PC automatically.
• Activation and license checks send the key, a one-way hashed machine ID (it cannot be turned back into your actual device details) and the app version to our server, so we can count how many PCs use the key. Details are in our privacy policy.

6. Your Pro license

• One key activates Visor Pro on up to 2 PCs at the same time, for personal or business use.
• The license is lifetime for version 1.x and does not expire as long as you follow these terms.
• Moving to a new PC: use “move to another PC” in the app, or uninstall Visor from the old PC; either releases that PC's seat, and you can then use the key on the new one. A PC that hasn't contacted the license server for 30 days gives its seat up automatically, or contact us and we will reset it.
• The key belongs to the buyer. Don't transfer, sell or share it beyond your own PCs, or your organization's PCs, within the seat limit.

The software is licensed to you, not sold. Tetono keeps all copyright and other intellectual property rights in it.

Third-party software: Visor includes open-source components such as LibreHardwareMonitorLib (MPL-2.0), each under its own license; nothing in these terms limits your rights under those licenses. PawnIO is a separate program from its own developer, installed only if you choose to, under its own license.

7. Pro trial

You can try the Pro features free for 7 days from inside the app, with no card required, once per PC. When the trial ends, the app returns to the free edition automatically. You are never charged.

8. Updates

Visor Pro buyers get every 1.x update free. If we ever release a next major version (for example 2.0) with substantial new development, it may be sold separately. We will say so clearly in advance, and the 1.x version you bought keeps working as before.

We may improve, add or change features for safety and Windows compatibility, but we will not reduce the core Pro capabilities you paid for without good reason.

9. What is not allowed

• Sharing, selling, renting or publicly posting license keys.
• Cracking, generating fake keys, or bypassing, blocking or modifying the licensing and activation system.
• Redistributing, reselling or modifying the software, or bundling it with other software.
• Reverse engineering, decompiling or disassembling the software, except where applicable law expressly permits it.
• Using the software for anything illegal, or on computers you are not authorized to manage.

10. Your responsibilities

Visor is read-only by design: it doesn't control fans, overclock, change voltages or touch the BIOS. One-click fixes can only change the display refresh rate, power plan and Windows Game Mode, and each asks first and can be undone. Still, every PC is different, so please:

• Follow BIOS steps (such as XMP / EXPO) carefully, and turn them back off if your PC becomes unstable.
• Treat Visor's readings as information, not as your only protection against heat; your hardware has its own safeguards.
• Back up important data regularly, especially if Visor warns about drive health.
• Update drivers and Windows from official sources only.

11. Warranty

We develop and test Visor carefully, but no software is entirely free of errors. To the extent permitted by law, the software is provided “as is”, and we don't guarantee that it will run without errors or interruption or suit every particular purpose you may have.

This does not exclude or limit any rights you have as a consumer that cannot be waived under Thai law or the mandatory law of the country where you live. If the software is defective and can't do what we describe, tell us and we will fix it or refund you as appropriate.

12. Limitation of liability

To the maximum extent permitted by law:

• Our total liability relating to the software and these terms is limited to the amount you paid us for Visor Pro (for the free edition, zero, unless the law says otherwise).
• We are not liable for indirect or special damages, lost profits, or data loss that you could have prevented by keeping regular backups, or damage from changes you made yourself in the BIOS or with other software.

These limits do not apply to liability that cannot be excluded or limited by law, such as liability for our fraud or gross negligence under Section 373 of Thailand's Civil and Commercial Code, or for injury to life, body or health.

13. Refunds

If you are not happy with Visor Pro, you can get a full refund within 14 days of purchase, no reason needed. The steps and conditions are in our refund policy, which forms part of these terms.

14. Termination

• Your rights under these terms end immediately if you break the rules in section 9, and we may revoke keys that were shared, sold or obtained improperly.
• If a purchase is refunded, or a payment is declined or reversed (chargeback), the key is revoked. Pro features stop on every PC using it, but the free edition keeps working.
• You can stop at any time by uninstalling Visor. The uninstaller releases the PC's seat on your key and asks whether to delete the program's data folder too.

15. Privacy

Visor collects no usage data and never sends your hardware details, sensor readings or history anywhere. We only collect the personal data needed to sell and activate licenses. See our privacy policy for details.

16. Changes to these terms

We may update these terms when our service or the law changes, and we show the date of the latest update at the top of this page. If a change significantly affects your rights, we will give reasonable advance notice on the website or by email. Changes never retroactively reduce what a license you already bought includes.

17. Governing law

These terms are governed by and interpreted under the laws of the Kingdom of Thailand. If a dispute arises, we would much rather talk it through and find a fair solution first. If we can't agree, the competent courts of Thailand will decide. Choosing Thai law does not deprive you of the protection of mandatory consumer laws of the country where you live. If any part of these terms is unenforceable, the rest remains in effect.
