Tago Voca Privacy Policy
Effective August 28, 2026 · Last updated August 28, 2026
This Privacy Policy explains how Tago Company, operated by Chanwoo Song, handles information in Tago Voca, a Korean vocabulary-learning app.
1. Guest use and information on the device
Tago Voca can be used without an account. Learning preferences, saved words, review history and schedules, streaks, cached pronunciation, and downloaded learning assets are stored on the device. Search terms are processed on the device and are not uploaded as search history. On-device information is not used for advertising or tracking.
2. Optional account and cloud backup
If a learner chooses Apple or Google sign-in, Tago Voca and Supabase Auth process a user identifier, sign-in provider, email address, and any basic authentication profile information the provider makes available. Tago Voca uses this information only to authenticate the learner, link a shared Tago Account, and restore learning records across devices.
For a connected account, Tago Voca stores saved-word identifiers, review status and scheduling data, review results, and synchronization timestamps in Supabase. These records are linked to the Tago Account and are used for app functionality and personalized learning continuity.
3. Google user data
Google Sign-In is optional. Tago Voca does not request access to Google Drive, Gmail, contacts, calendars, or other Google service content. Google account information is not sold, shared for advertising, used for tracking, or used to create advertising profiles.
4. Service providers
- Supabase provides optional authentication, database, and server functions for account linking, synchronization, and deletion.
- Apple and Google provide optional social sign-in and process information under their own privacy policies.
- Cloudflare delivers pronunciation and learning assets. Asset requests may involve standard network information such as an IP address, request time, and requested file, but Cloudflare does not receive Tago learning records through these requests.
Providers may process information outside the learner's country only as necessary to operate their services. Tago Voca requires providers that process data on its behalf to protect it consistently with this policy.
5. Analytics, advertising, and tracking
The current release contains no third-party advertising, cross-app tracking, or product analytics. Tago Voca does not sell personal data.
6. Retention, choices, and deletion
On-device learning information remains until the learner resets Voca data, clears the app's data, or deletes the app. Cloud account and learning information is retained while the connected Tago Account is active or as needed to provide the service.
In Settings, Reset Voca data clears Voca learning data on the device and in the Voca cloud backup while keeping the Tago Account. Delete Tago Account deletes the shared account and related server data across connected Tago apps. Because on-device Voca progress is intentionally usable without an account, a learner who wants to erase both cloud and device data should reset Voca data before deleting the account. Routine backup deletion cycles and limited retention required by law may still apply.
7. Security and children
Tago Voca uses encrypted transport, authentication, and access controls. It is a general-audience educational app and is not directed specifically to children. A learner who requires consent from a parent or guardian must obtain it before connecting an account.
8. Changes and contact
This policy may be updated as Tago Voca changes. Material changes will be
reflected by updating the date above and communicated when required.
