Sign-in Terms
These terms describe the shared sign-in service provided by GNSOFTECH Co., Ltd. where a participating product offers it. Separate product terms, store rules, and purchase information apply to each product. This page does not announce that a product or payment feature is available in every region or version.
1. Your sign-in identity
Use a sign-in identity you are authorised to control. Keep access to the provider account secure and tell us if you suspect unauthorised use. Do not impersonate another person, misuse another account, or bypass access restrictions. We may require ownership verification before changing an account or responding to a sensitive request.
2. App membership is separate
The same GNSOFTECH identity can be used by participating apps, but each app keeps its own membership. Joining one app does not automatically join every other app. A closed app membership may require an explicit request to rejoin.
Local app data and any product-specific synchronisation features follow that product's own behaviour and notices. Shared sign-in alone does not guarantee data synchronisation or transfer.
3. Purchases stay with the purchased edition
GNSOFTECH sign-in itself does not make a purchase or grant paid access. For VuvoLingo, Web, Windows, Google Play, Apple App Store, and Apps in Toss purchases remain separate. Using the same identity does not unlock another edition or store.
Restore purchases, manage renewal, cancel a subscription, or request a refund through the edition or store where you purchased. Signing out, revoking Google access, or requesting account removal does not automatically cancel a subscription or refund a payment. These sign-in terms do not change the price, duration, or benefits stated when you purchased.
4. Account and removal requests
Use the account controls available in your app or contact support@gnsoftech.com. State whether you mean one app's membership or the shared GNSOFTECH account. We confirm ownership and scope before carrying out a sensitive change.
Shared-account removal can affect other participating apps. Some information may need to be retained for security, disputes, or legal obligations, as explained in the Sign-in Privacy Notice. We do not treat removal of one app membership as permission to delete unrelated apps, local device data, or payment-provider records.
5. Availability and changes
Sign-in availability depends on the app, version, provider, and service status. We may change or temporarily restrict sign-in to maintain security, perform maintenance, or respond to abuse. Contact support if this prevents you from accessing a purchased service. Applicable consumer rights and product-specific purchase obligations are not removed by these terms.

Questions about sign-in or these terms: support@gnsoftech.com. Never send your password, sign-in code, or full payment-card details.
