Terms of Service

Effective Date: August 22, 2026

These Terms of Service (“Terms”) govern your use of VirtualTablet, VirtualTablet: Bluetooth, their companion computer software, and related services provided by Sunnysidesoft (“we”, “us”, or “our”). Together, these products and services are referred to as the “Services”.

By downloading, installing, purchasing, or using any part of the Services, you agree to these Terms. If you do not agree, do not use the Services.

1. Eligibility

You must be legally capable of entering into a binding agreement to use the Services. If you are under the age of legal majority where you live, you may use the Services only with permission from a parent or legal guardian. The parent or guardian is responsible for the minor’s use of the Services.

2. What the Services Do

The Services turn a compatible mobile device or tablet into an input device for a compatible computer. Features may include transmitting stylus position, pressure, tilt, twist, button, touch, mouse, or keyboard input.

• VirtualTablet connects through a local Wi-Fi network or a supported USB connection and generally requires the VirtualTablet Server software on the receiving computer.
• VirtualTablet: Bluetooth connects through Bluetooth. It depends on compatible Bluetooth hardware and operating system support. Windows and Linux may work without companion software, while macOS requires the VirtualTablet: Bluetooth Agent.

Available features and performance depend on your devices, stylus, operating systems, drivers, connection quality, Bluetooth implementation, local network, and third-party applications. Not every feature is available on every device or platform.

3. License to Use the Services

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, and revocable license to install and use the Services on devices that you own or control. You may use the Services for personal, educational, or professional creative work, subject to the rules of the store or platform from which you obtained them.

This license does not transfer ownership of the Services or any related intellectual property to you.

4. Acceptable Use

You agree not to:

• Copy, sell, rent, sublicense, redistribute, or commercially exploit the Services except as expressly permitted by us
• Reverse engineer, decompile, disassemble, or attempt to obtain the source code of the Services, except where applicable law expressly allows it
• Bypass, disable, or interfere with license checks, purchase validation, advertising, security, or technical restrictions
• Modify the Services or create derivative works from them without our permission
• Use the Services to violate any law, infringe another person’s rights, introduce malicious code, or interfere with devices, networks, or services
• Misrepresent your relationship with Sunnysidesoft or use our names, logos, or trademarks without permission

5. Your Devices, Connections, and Content

You are responsible for obtaining compatible devices, operating systems, drivers, applications, network access, Bluetooth access, cables, and any other equipment needed to use the Services. You are also responsible for securing your devices, local network, Bluetooth pairings, and computer access.

The Services transmit input to a computer and may control its pointer, keyboard shortcuts, or other actions. You are responsible for confirming the target computer and application before sending input. You should save and back up your work. We are not responsible for unintended input, unsaved work, or loss caused by your device, connection, software, or configuration.

You retain ownership of artwork, documents, and other content you create using the Services. These Terms do not grant us ownership of that content.

6. Permissions and Local Data Transmission

Some features require access to your local network, nearby devices, Bluetooth, microphone, or other system permissions. For example, the SonarPen feature uses microphone input locally to detect pen pressure and button state. Denying a permission may prevent the related feature from working.

Stylus and input data is sent directly between your devices through the selected local connection and is not intended to be stored by Sunnysidesoft. Our handling of analytics, diagnostics, advertising, purchase information, and other data is described in the applicable Privacy Statement:

• VirtualTablet Privacy Statement
• VirtualTablet: Bluetooth Privacy Statement

7. Free Features, Advertising, and Paid Features

The Services may include free features supported by advertising and optional paid features. The features, prices, billing periods, trial terms, and availability shown in the applicable app or store at the time of purchase form part of your purchase terms. Prices and offerings may differ by platform, country, currency, tax, or store policy.

We may add, change, or discontinue free or paid plans for future purchases. Any effect on an existing purchase or subscription is subject to the purchase terms, applicable store rules, and applicable law.

8. Purchases and Subscriptions

Purchases are processed by the store or platform through which you make them, such as Google Play, the Apple App Store, or the Microsoft Store. The store’s payment terms also apply. We do not directly receive or store your full payment card details.

If you purchase an auto-renewing subscription:

• The store charges your account at the price and billing interval displayed when you subscribe
• The subscription renews automatically unless you cancel it through the store before the renewal deadline shown by that store
• Deleting the app does not cancel a subscription
• Cancellation normally stops future renewals, and access generally continues until the end of the paid billing period unless the store or applicable law provides otherwise

One-time purchases provide access to the purchased feature for the product, platform, and store account identified at the time of purchase. “Lifetime” or similar wording refers to the supported lifetime of that purchased product and does not guarantee that the Services, a store, a platform, or a particular feature will remain available indefinitely.

Purchase restoration and use on additional devices depend on the store account, store rules, product configuration, and platform compatibility. Purchases may not transfer between different stores, platforms, products, or accounts.

9. Cancellations and Refunds

You can manage or cancel a subscription through the account settings of the store where you purchased it. Refund eligibility and processing are governed by the applicable store policy and mandatory consumer law. Except where required by law or allowed by the applicable store, payments are non-refundable and we do not provide credits for a partially used billing period.

If a purchase is refunded, reversed, or charged back, access to the related paid features may be removed. Contact [email protected] if a valid purchase is not recognized after you have tried the store’s purchase restoration process.

10. Third-Party Services and Software

The Services may interact with app stores, operating systems, device drivers, Bluetooth components, local networks, graphics applications, Firebase, AdMob, RevenueCat, or other third-party products and services. Their own terms and privacy policies apply to your use of them.

We do not control third-party products or services and are not responsible for their availability, security, compatibility, content, or changes. References to compatible devices or applications do not imply sponsorship or endorsement by their providers.

11. Updates and Changes to the Services

We may provide updates, bug fixes, security changes, new features, or other modifications. Some updates may be required for continued use, compatibility, or security. Automatic updates may occur through the Services, your operating system, or the applicable store, depending on your settings.

We may change, suspend, or discontinue all or part of the Services. When reasonably practical, we will provide notice of a material change that significantly affects paid functionality. We do not guarantee support for every device, operating system, driver, or third-party application indefinitely.

12. Intellectual Property

The Services, including their software, design, text, graphics, logos, and other materials, are owned by Sunnysidesoft or our licensors and are protected by intellectual property laws. All rights not expressly granted in these Terms are reserved.

If you send us feedback or suggestions, you allow us to use them without restriction or compensation to improve or develop our products. This does not give us ownership of your artwork, documents, or other content created with the Services.

13. Disclaimer of Warranties

To the fullest extent permitted by law, the Services are provided “as is” and “as available.” We do not guarantee that the Services will always be available, uninterrupted, secure, error-free, compatible with every configuration, or suitable for a particular purpose. Drawing latency, input accuracy, pressure response, connection stability, and other performance can vary based on factors outside our control.

Nothing in these Terms excludes warranties, guarantees, or other rights that cannot legally be excluded under applicable consumer law.

14. Limitation of Liability

To the fullest extent permitted by law, Sunnysidesoft will not be liable for indirect, incidental, special, consequential, or punitive damages, or for loss of profits, revenue, data, goodwill, or business opportunity arising from or related to the Services.

To the fullest extent permitted by law, our total liability for claims relating to the Services will not exceed the amount you paid for the affected Service during the 12 months before the event giving rise to the claim.

These limitations do not apply to liability that cannot be limited or excluded under applicable law, including any mandatory consumer rights.

15. Suspension and Termination

You may stop using the Services at any time. We may suspend or terminate your right to use the Services if you materially or repeatedly violate these Terms, use the Services unlawfully, or create a security risk. Where appropriate, we will provide reasonable notice and an opportunity to correct the violation.

When your right to use the Services ends, the license granted under these Terms ends. Sections that by their nature should continue after termination will remain in effect, including sections concerning ownership, disclaimers, limitations of liability, and disputes. Termination does not automatically cancel a store subscription; you must cancel it through the applicable store.

16. Changes to These Terms

We may update these Terms to reflect changes to the Services, law, security requirements, or business practices. We will update the Effective Date above and, when required, provide additional notice through the Services or our website.

Changes apply prospectively from their effective date. If you do not agree to updated Terms, you must stop using the Services and cancel any active subscription before its next renewal.

17. Governing Law and Disputes

These Terms are governed by the laws of the Republic of Korea, without regard to its conflict-of-law principles. However, this choice of law does not deprive you of any mandatory consumer protection rights available under the laws of the country where you habitually reside.

Before starting formal proceedings, you and Sunnysidesoft agree to make a reasonable effort to resolve the dispute by contacting the other party, unless immediate action is necessary or this requirement is prohibited by law.

Any unresolved dispute may be submitted to a court having jurisdiction under applicable law. Nothing in these Terms limits your right to bring a claim before a court in your place of residence where that right is provided by applicable consumer law.

18. General Terms

If any provision of these Terms is found unenforceable, the remaining provisions will continue in effect. Our failure to enforce a provision is not a waiver of our right to do so later. You may not transfer your rights or obligations under these Terms without our consent. We may transfer these Terms as part of a merger, acquisition, reorganization, or sale of assets, subject to applicable law.

These Terms, the applicable Privacy Statement, and any purchase terms displayed by the applicable store form the entire agreement between you and Sunnysidesoft regarding the Services, except where additional terms are expressly presented for a particular feature or platform.
