1. Information We Collect

When you use GESTEL, we may collect the following information for social login (Google, Kakao) and service provision:

  • Account Information (Required) — Email address, display name, and identifier (ID) provided when creating an account and logging in.
  • Marketing Consent Data (Optional) — Phone number (only if you explicitly opt-in to receive marketing communications).

2. How We Use Information

The collected information is used for the following purposes:

  • Platform Operations (Required) — To provide and improve the GESTEL platform, process image generation and editing requests, verify identity and authenticate users, send service updates and critical notices, and prevent abuse to ensure platform security.
  • Marketing Activities (Optional) — To send promotional and marketing information, including updates on new GESTEL features, promotional benefits, discount coupons, and event details (via Email, KakaoTalk, SMS, etc.).

3. Data Storage and Retention

  • Images — Uploaded images are stored temporarily for processing. Generated images are stored for a limited time to allow you to download them. We do not retain images indefinitely unless you explicitly save them to your account.
  • Account & Personal Information — As a rule, personal information is destroyed without delay upon account deletion or withdrawal of consent for marketing communications. (However, if preservation is required by relevant laws and regulations, the information will be securely retained for the legally specified period).

4. Third-Party Services & Consignment of Processing
