Sign-up, Email Verification & Sign-in Troubleshooting

Welcome to "Anxin Learn". If something goes wrong while creating an account, getting an email code, or signing in on another device, follow these steps.

[!TIP] 30-second sign-in quick-start

  • No verification code? Check your spam folder first; double-check the email spelling (like .com mistyped as .con);
  • Cooldown & anti-spam: code sending has a 60-second cooldown — don't spam the button within the hour;
  • Offline sandbox still works: even without signing in or an internet connection, local videos, pacing, and check-ins all run 100%;
  • Use a mainstream mailbox: if a corporate or strict mailbox blocks our mail, switch to 163, QQ, Gmail, or Outlook.

1. Email Verification Code Troubleshooting

1.1 The 4-step self-check

  1. Check spam / subscriptions: the code mail is sent automatically; some providers misclassify it as ads;
  2. Verify the spelling: check for stray spaces, hidden dots, or .com typed as .con / .cn;
  3. Allow network time: the code usually arrives in 5–30 seconds, but cross-network delays of 1–2 minutes happen — please wait;
  4. Try a mainstream mailbox: if it still doesn't arrive, register again with 163, Gmail, Outlook, or QQ.

2. Common Sign-in & Network Issues (FAQ)

Q: Why don't I get the email verification code?

Run through the self-check above. The most common cause is anti-spam filtering by your provider. Search your mail for "Anxin Learn" or "SafeHouse", or check spam.

Q: Are there sending frequency limits?

Yes, to prevent abuse:

  • 60-second cooldown: you must wait 60 seconds between sends;
  • IP & device anti-abuse: requesting too often within an hour can trigger a 15–30-minute temporary block — don't keep mashing the button.

Q: Can I use "Anxin Learn" without signing in?

Absolutely! The app follows its "local-first sandbox" principle. Without signing in, you can still add local offline videos, set eye-care limits, use pacing, and accumulate stars — all stored on-device. Signing in is mainly for syncing benefits across devices and secure recovery.

Q: How do I move data to a new phone or tablet?

Use [[Parent Center]] → [[Face-to-Face Transfer]] with both devices on the same Wi-Fi — dozens or hundreds of videos transfer in seconds. Or export a backup on the old device and import it on the new one.
