- the parents section is gone: no parent login, invite codes or "I'm a parent" button; "گزارشِ والدین" in the profile shows the week against the previous one (praise line, six tiles, minutes-per-day and right/wrong-per-day charts, a table of the numbers) - birth date as day / month / year selects (Jalali, leap Esfand handled) instead of age; adults (19+) are asked which grade's math they want to learn - user ID under the name, copyable - "پرداخت‌ها و فاکتورها": every order with invoice number, discount, amount and reference code - tutor: when the free daily quota runs out, a button to the subscription page instead of "retry" Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
