Frequently Asked Questions (FAQ)

Answers to practical everyday questions encountered by organizers and participants managing rotating savings groups on Huio.

---

1. Cycle Openings & Bidding Operations

What happens if two or more members submit matching highest bids?

In the event of a tie bid, the organizer taps the Random Spin Wheel button on the closing screen. Huio launches an animated, provably fair spin wheel restricted solely to those tied participants, ensuring a transparent winner selection in front of the group.

What should we do if no one submits a bid at the deadline?

If no participants submit a bid (all wishing to continue saving), the host can trigger the Random Spin Wheel. The system randomly selects one eligible live slot to receive the period payout with a winning bid interest of 0 ₫ (interest-free payout).

How do I correct an accidental wrong winner or erroneous bid entry?

Huio provides a built-in Rollback Last Period safeguard:

1. Open the affected group -> switch to the Settings tab.
2. Tap Rollback Last Period and confirm.
3. The cycle reverts to open status, and the mistakenly chosen winner returns to live slot standing for immediate re-adjudication.

Can elderly members without smartphones participate?

Yes, seamlessly. Huio empowers organizers to manage the entire chain on behalf of non-smartphone users:

• The host enters member names and mobile numbers into the directory.
• Each cycle, the host exports bills and receipts as images or text to share via Zalo, SMS, or physical printouts.
• Participants simply transfer funds using the provided Napas VietQR code or pay in cash.

2. Payments & Financial Calculations

How do live slots and dead slots differ in contribution amounts?

• Live Slots (Chân sống - net savers): Receive the interest discount from the winning bid. Actual amount paid = Base Share − Winning Bid Amount.
• Dead Slots (Chân chết - payout recipients): Have already received their lump sum payout. Actual amount paid = 100% Base Share (no interest discount).

How do I record a partial installment payment?

Under the Collection tab of the group:

1. Tap the row of the member who made a partial payment.
2. Enter the partial cash amount actually received (e.g. required 2,000,000 ₫, received 1,000,000 ₫).
3. Huio records the partial cash-in and logs the remaining balance (1,000,000 ₫) directly into the Debtors Ledger for automated overdue tracking.

What if a member transfers funds with an incorrect or missing memo?

Funds arrive safely in the organizer's bank account regardless. The organizer simply:

1. Navigates to Finance -> Bank Transactions.
2. Locates the unrecognized transaction -> taps Match Manually.
3. Selects the appropriate group and slot to allocate the payment and mark it as paid.

When is the host commission (tiền thảo) calculated?

Depending on group setup:

• Per Win (on_win): Deducted from each winning member's payout during every individual cycle.
• Upfront Period 1 (on_open): Collected in a single lump sum from all participants during Period 1. Subsequent period winners receive 100% of the collected pool.

3. Security, Data Integrity & Recovery

What is the purpose of the Net Balance (Âm dương) metric in preventing defaults?

A member's cumulative financial balance is defined as: $$\text{Net Balance} = \text{Total live contributions paid} - \text{Remaining dead installment liabilities}$$

• Early winners carry significant negative balances (outstanding liabilities to the pool).
• By auditing this balance in the member's profile, organizers can enforce healthy debt limits and prevent over-extension or absconding (giật hụi).

What happens to my records if I lose or change my phone?

Your financial ledger is completely safe. All groups, participant records, and transaction histories are securely synchronized in real time to the cloud. On a new device, simply sign in with your verified phone number and OTP code to restore your entire ledger.

Can I recover a group deleted by accident?

Yes. Huio includes a safety Recycle Bin:

1. Go to Settings -> Deleted Groups.
2. Locate the deleted group and tap Restore. All cycles, slot assignments, and payment histories are restored immediately.

How do I prevent unauthorized individuals from viewing my ledger?

Configure a 4-digit App PIN and enable Biometric Authentication (Face ID / Fingerprint) in Settings. The application locks automatically upon exit, ensuring privacy.
