1. Agreement to Terms

These Terms of Service ("Terms") govern your use of any software application, website, or related service provided by Glanz Studio ("we", "our", or "us"). By downloading, installing, accessing, or using any of our applications — including, without limitation, LockStudy, Névo, Noopdda, Lumen, GymGate, and WatchDog (collectively, the "Apps") — or any future application released by Glanz Studio, you agree to be bound by these Terms. If you do not agree, please do not use our Apps or Services. Your use is also subject to the Glanz Studio Privacy Policy, which is incorporated into these Terms by reference.

2. License

Glanz Studio grants you a limited, non-exclusive, non-transferable, revocable license to download and use the Apps for personal, non-commercial purposes on devices that you own or control. You may not sublicense, sell, resell, transfer, assign, distribute, or otherwise commercially exploit the Apps. All rights not expressly granted herein are reserved by Glanz Studio.

3. Use of Services

You agree to use our Apps only for lawful purposes and in accordance with these Terms. You shall not: (a) use the Apps in any way that violates any applicable law or regulation; (b) attempt to reverse-engineer, decompile, or disassemble the Apps; (c) attempt to gain unauthorized access to any part of the Apps; (d) use the Apps to transmit any harmful code or interfere with their operation; or (e) use the Apps for any purpose that is competitive with Glanz Studio.

4. Purchases & Payments

Glanz Studio sells our Apps through two distribution channels, each governed by its own payment processor:

4.1 Apple App Store (iOS Apps). LockStudy, Névo, Noopdda, Lumen, and GymGate are distributed through the Apple App Store. Noopdda, Névo, Lumen, and GymGate are paid applications. LockStudy is free to download with optional auto-renewable subscriptions and lifetime purchase options. All payments for these Apps are processed exclusively by Apple. Glanz Studio does not have access to your Apple ID, payment methods, or any financial information. All purchases are subject to Apple's terms and conditions.

4.2 Lemon Squeezy (macOS Apps via Direct Distribution). WatchDog and other macOS applications distributed outside the Mac App Store are sold through our Lemon Squeezy storefront. Lemon Squeezy acts as the Merchant of Record, meaning that Lemon Squeezy is responsible for processing payments, charging applicable taxes (including VAT/GST/sales tax), issuing receipts, and handling refunds. Glanz Studio does not store or process your payment card details. All Lemon Squeezy purchases are additionally subject to the Lemon Squeezy Terms of Service.

Prices may vary by region and currency and are subject to change. We may offer promotional pricing or limited-time discounts at our discretion.

5. Subscriptions

LockStudy offers auto-renewable subscriptions through the Apple App Store. Payment is charged to your Apple ID account at confirmation of purchase. Subscriptions automatically renew unless auto-renewal is turned off at least 24 hours before the end of the current billing period. Your account will be charged for renewal within 24 hours prior to the end of the current period. You can manage and cancel your subscriptions through your App Store account settings. Any unused portion of a free trial period will be forfeited when you purchase a subscription. Apps sold through Lemon Squeezy (such as WatchDog) are one-time purchases with lifetime access and do not involve any recurring subscription.

6. License Keys (Lemon Squeezy Apps)

Apps purchased through Lemon Squeezy are activated using a license key delivered by email upon purchase. Each license key is valid for use on a single device unless otherwise stated at the time of purchase. License keys are non-transferable and may not be sold, shared, sublicensed, or distributed. If you change devices, you may deactivate the license on your previous device through the App's settings and reactivate it on your new device. Refunded or revoked license keys are automatically invalidated and will no longer activate the App.

7. Refunds

7.1 App Store Purchases. All App Store purchases and subscriptions are processed by Apple. Glanz Studio does not have the ability to issue refunds for these transactions. For refund requests, please contact Apple Support directly or request a refund through your App Store purchase history at reportaproblem.apple.com.

7.2 Lemon Squeezy Purchases. For Apps purchased through Lemon Squeezy, we offer a full refund within 7 days of purchase, provided the license key has not been activated, or in cases where the App fails to function as described and we are unable to resolve the issue. To request a refund, please contact us at [email protected] with your order number. Refunds are issued through Lemon Squeezy and may take several business days to appear on your statement.

8. Intellectual Property

All content, features, functionality, design, graphics, trademarks, and source code of the Apps are and shall remain the exclusive property of Glanz Studio, protected by applicable copyright, trademark, and other intellectual property laws. You may not copy, modify, create derivative works from, distribute, sell, or otherwise exploit any portion of the Apps without prior written consent from Glanz Studio.

9. User Responsibilities

You are responsible for maintaining the security of your device and access to the Apps. We recommend that you do not jailbreak or root your device, as doing so may compromise security and cause the Apps to malfunction. You are responsible for all activity that occurs through your use of the Apps. You acknowledge that an internet connection may be required for certain features (such as initial license activation for Lemon Squeezy Apps), and that Glanz Studio is not responsible for the Apps not functioning if you lack connectivity.

10. Custom Work & 1:1 Services

Glanz Studio sells only standardized, off-the-shelf software products. We do not offer 1:1 services, custom development, white-label builds, or personalized product variants through any of our distribution channels. Every customer receives the same App binary as every other customer.

11. App Updates & Availability

Glanz Studio may update the Apps from time to time to improve functionality, fix bugs, or add new features. We reserve the right to modify, suspend, or discontinue the Apps (or any part thereof) at any time without prior notice. We are not liable to you or any third party for any modification, suspension, or discontinuance of the Apps. Continued use of the Apps after updates constitutes acceptance of the updated version.

12. Disclaimer of Warranties

THE APPS ARE PROVIDED ON AN "AS IS" AND "AS AVAILABLE" BASIS WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. GLANZ STUDIO DOES NOT WARRANT THAT THE APPS WILL BE UNINTERRUPTED, ERROR-FREE, SECURE, OR FREE OF VIRUSES OR OTHER HARMFUL COMPONENTS.

13. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, GLANZ STUDIO SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, DATA, USE, OR GOODWILL, ARISING OUT OF OR IN CONNECTION WITH YOUR USE OF THE APPS, WHETHER BASED ON WARRANTY, CONTRACT, TORT, OR ANY OTHER LEGAL THEORY. IN NO EVENT SHALL GLANZ STUDIO'S TOTAL LIABILITY EXCEED THE AMOUNT YOU PAID FOR THE APP IN THE 12 MONTHS PRECEDING THE CLAIM.

14. Governing Law

These Terms shall be governed by and construed in accordance with the laws of the Republic of Korea, without regard to its conflict of law provisions. Any disputes arising out of or related to these Terms or the Apps shall be subject to the exclusive jurisdiction of the courts located in Seoul, Republic of Korea.

15. Changes to Terms

Glanz Studio reserves the right to modify these Terms at any time. Changes will be posted on this page with an updated revision date. Your continued use of the Apps after any changes constitutes acceptance of the revised Terms. We encourage you to review these Terms periodically.

1. Overview

Glanz Studio ("we", "our", or "us") is committed to protecting your privacy. This Privacy Policy explains how we handle information in connection with all applications, websites, and related services we provide — including, without limitation, LockStudy, Névo, Noopdda, Lumen, GymGate, and WatchDog (collectively, the "Apps") — and any future application released by Glanz Studio (together with the Apps and our website, the "Services").

2. Data We Do Not Collect

We do not collect any personal data through our Apps. Specifically, our Apps do not: require account creation or registration with Glanz Studio; collect your name, email address, phone number, or any other personally identifiable information for our own use; track your location, browsing activity, or cross-app usage behavior; use cookies, pixels, advertising identifiers, or any tracking technologies; or transmit any usage data to Glanz Studio servers. We do not operate any servers that store user information. We believe in building useful apps without compromising your privacy.

3. App-Specific Permissions

Some Apps request permissions that are required to deliver their core functionality. All data accessed through these permissions is processed locally on your device and is never transmitted to Glanz Studio.

Névo accesses your photo library solely to apply filters; photos are processed locally and never uploaded.

WatchDog (macOS) monitors which application is currently in the foreground and detects keyboard/mouse idle state on your device in order to provide focus-session feedback. This information is processed locally on your Mac in real time and is never recorded, stored remotely, or transmitted off your device. WatchDog does not read the contents of any application, document, or input.

Other Apps may request standard iOS or macOS permissions (such as notifications) only when needed for their stated features. You can review and revoke these permissions at any time in your device's system settings.

4. Local Data Storage

All data generated through the use of our Apps — including settings, preferences, focus history, and progress — is stored exclusively on your device. We do not operate servers that store your personal information. If you delete an App, all locally stored data associated with that App will be permanently deleted.

5. Third-Party Services

We do not use any third-party analytics, advertising, or behavioral-tracking services, and we do not integrate any SDKs that collect user data for our own use. The following third parties are involved only when you make a purchase or perform a software update:

5.1 Apple App Store. When you purchase or download our iOS Apps (LockStudy, Névo, Noopdda, Lumen, GymGate), Apple processes the transaction and any related personal data under Apple's Privacy Policy. Glanz Studio does not receive your Apple ID, payment details, billing address, or other financial information.

5.2 Lemon Squeezy. When you purchase WatchDog or any other macOS App distributed via direct distribution, payment is processed by Lemon Squeezy ("Sold through Link, LLC f/k/a Lemon Squeezy LLC"), which acts as the Merchant of Record. Lemon Squeezy collects the information necessary to complete the transaction, including your email address, billing/shipping address, payment card or PayPal details, IP address, and the country used to determine VAT/sales tax. Glanz Studio receives only non-financial order information (such as the product purchased, the order ID, and the email address used at checkout) so that we can deliver your license key and provide customer support. Lemon Squeezy's handling of your data is governed by the Lemon Squeezy Privacy Policy.

5.3 Software Updates. Apps distributed through the Apple App Store are updated by Apple. macOS Apps distributed directly may check for updates by retrieving a small public update manifest hosted on a content delivery network; this request reveals only routine connection information (such as IP address) to the hosting provider and does not include any personally identifiable information.

6. Purchases & Financial Data

For App Store purchases, Apple is the seller and processes all payment data. For Lemon Squeezy purchases, Lemon Squeezy is the Merchant of Record and processes all payment data. In neither case does Glanz Studio store, see, or have access to your full payment card number, CVC, or bank account details.

7. License Keys (Lemon Squeezy Apps)

When you purchase an App through Lemon Squeezy, we receive a license key associated with the email address you provided at checkout. This license key, together with a hardware-derived activation identifier generated at activation time, is stored by Lemon Squeezy in order to enforce per-device activation limits and to invalidate keys after refund. The activation identifier is a non-reversible token and does not contain personally identifiable information about your hardware.

8. Children's Privacy

Our Apps are safe for users of all ages. Since we do not collect any personal information ourselves, there is no risk of Glanz Studio collecting data from children under the age of 13 (or the applicable age in your jurisdiction). We comply with the Children's Online Privacy Protection Act (COPPA) and similar regulations worldwide. Purchases must be made by an adult or with appropriate parental consent through the relevant store's family-purchase mechanisms.

9. International Users (GDPR, CCPA, and Similar Laws)

Glanz Studio is based in the Republic of Korea, and our Apps are available globally. Because we do not collect or store personal data ourselves, the rights granted by privacy laws such as the EU General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA/CPRA), and similar regulations are fully respected by our zero-data-collection approach. For data handled by Apple or Lemon Squeezy in connection with your purchase, please refer to those companies' respective privacy policies and exercise your rights with them directly.

10. Your Rights

Since we do not collect or store any personal data, there is no personal data for us to provide, modify, or delete. You can delete all locally stored data at any time by simply deleting the App from your device. For any account or payment data held by Apple or Lemon Squeezy, please contact those services directly.

11. Security

While we do not collect or transmit personal data, we take reasonable measures to ensure the security and integrity of our Apps. macOS Apps distributed directly are signed with our Apple Developer ID and notarized by Apple before release. All data remains on your device and is protected by your device's built-in security features.

12. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page with an updated revision date. We encourage you to review this policy periodically. Your continued use of the Apps after changes constitutes acceptance of the updated policy.
