5. Children's Privacy and Parental Role
AIKO is tailored for primary school students. Accounts should be created by, or with the verified consent of, a parent or legal guardian.
Parents and legal guardians reserve the right to: inspect, modify, delete their child’s data, and withdraw consent at any time (see Section 8).
The application contains zero advertisements and no commercial purchase links.
Students are instructed to frame only the homework area, avoiding faces or personal identifiable notes. In the event such data is unintentionally captured, it is processed solely for academic grading.
6. Data Retention Period
Account data is retained until the user requests account deletion.
Homework photos: stored together with grading results so you can review them, until the account is deleted.
Grading history and learning progress: retained until account deletion.
When you request account deletion, the account is locked immediately and its data (including homework photos and grading results) is permanently deleted after 7 days, unless a longer retention period is required by law.
