Parental Controls & Safety: The Complete Overview

The core idea of "Anxin Learn" is simple: give parents full control over what their child watches and when.

This guide covers the two-level child lock (anti-guessing), the clean whitelist sandbox, the three-in-one time management system, and recommended settings for every age.

[!TIP] 30-second parental control quick-start

  • You curate everything: 100% whitelist-only content — no "suggested for you", no recommendation feed, and comments, danmaku, and ads are all filtered out;
  • Two-level child lock: Starts with a Chinese-character challenge; once your child can read, upgrade to a 4-digit PIN lock with one tap;
  • Three-in-one time control: Continuous-session limit (eye care) + per-category limits (learning vs. fun) + Scheduled Pacing (delayed gratification);
  • Forgot your password? Tap [[Forgot Password]] and reset it through an adult-verification challenge — nothing is ever lost.

1. Parent Verification & the Anti-Breakable Child Lock

1.1 Two levels of protection

As children learn to read, the default Chinese-character challenge (like "叁 陆 玖") can eventually be solved. So we provide two levels:

  1. Default mode (Chinese characters → numbers): Perfect for preschoolers; prevents stray taps from entering;
  2. 4-digit PIN lock:
    • Go to [[Parent Center]] → tap [[Security Settings]] → turn on [[Password Protection]];
    • Set a 4-digit PIN only you know;
    • Optionally add a memory hint (for example: "last two digits of our anniversary");
    • Once on, the PIN is required for entering Parent Center, exiting the app, or changing time limits.

1.2 Forgot your PIN?

  1. In the password pop-up, tap [[Forgot Password]] at the bottom;
  2. An advanced adult-verification challenge appears (like deciphering an uncommon idiom or solving a multi-step calculation);
  3. Pass it and the PIN is reset instantly — no reinstall needed, and all history is 100% preserved.

2. A Clean Digital Space, by Design

  • :icon(shield): Absolute whitelist: Your child can only see the videos, audio, and collections you added — no "you might like", no recommendation stream, no unsupervised global search;
  • :icon(tv): No danmaku, no comments: Bilibili and web videos play with all danmaku, comment sections, and affiliate ads stripped away — a quiet digital sanctuary;
  • :icon(wifi): Local-first sandbox: All rules, viewing history, and check-in records live in an encrypted local database on the tablet — no third-party tracking, ever.

3. The Three-In-One Time Management System

Tool & where to find itWhat it solves & when to use
Eye Care Limit
:icon(time): Parent Center → Time Management		Rest for young eyes: Force a 10-minute look-into-the-distance break every 20 minutes of viewing to protect long-term eyesight.
Per-Category Limits
:icon(category): Parent Center → Screen Time Control → Per-Category Limits		Learning vs. fun balance: Give high-dopamine entertainment animation different rules than deep science content — lock it on weekdays, open it on weekends.
Scheduled Pacing
:icon(calendar): Parent Center → Pacing Management		Builds delayed gratification: Prevents binge-watching a 50-episode series in one day; episodes unlock on a set schedule.

4. Recommended Settings by Age

  • 👶 2–4 years (early stage):
    • Content: bilingual nursery rhymes in audio-only mode, habit & feelings picture books;
    • Settings: 15-minute session limit, keep the default character challenge on.
  • 👦 5–7 years (school prep):
    • Content: fun Chinese classics, math & logic, nature encyclopedia;
    • Settings: switch to the 4-digit PIN, schedule pacing (1 episode per day), and use the Star Rewards system to build a check-in habit.
  • 🧑 8+ years (independent exploration):
    • Content: deep documentaries, classic book lectures, kids' coding;
    • Settings: keep science categories unlimited, cap entertainment animation to weekends, and let your child explore the Growth Dashboard to develop planning skills.

5. FAQ

Q: My child can read now and figured out the character challenge — what do I do?

Go to [[Parent Center]] → [[Security Settings]] and turn on the 4-digit PIN lock right away. Your child can't guess their way past a PIN.

Q: Will the app push ads or viral short videos to my child?

Never. "Anxin Learn" has no algorithm recommendation feed. Every single video your child sees was hand-picked and added by you.

Q: What if I forget my own PIN?

Tap [[Forgot Password]] at the bottom of the password screen, pass the built-in adult challenge, and it's reset instantly — no wiping, no reinstall.
