DEEPNICHE · UPDATED 10/27/2026

Operating rules

These Regulations govern the operation of the DeepNiche e-commerce platform (owned and operated by Mr. Lê Văn Vĩnh Phước; “DeepNiche”, “we”), and are established under the Law on E-commerce No. 122/2025/QH15 and Decree No. 248/2026/ND-CP.

DeepNiche is a direct-sales e-commerce platform with online ordering functionality: DeepNiche is the sole seller of products and services on DeepNiche, including the DeepNiche online content research software (pay-per-wallet, monthly / annual plans), digital products (AI Skills, AI Assistants, apps, online courses), and reseller plans. Reseller stores (addresses in the form /dl/reseller-code/ on DeepNiche) are operated by the resellers themselves: reseller customers pay the reseller directly, and the reseller is responsible for customer care, reconciliation, and invoicing for their own customers.

Customers who create an account, place an order, or pay on the platform are deemed to have agreed to these Regulations together with the Terms of use, Privacy policy and Payment & Refund Policy.

Intake channels (all online, except phone):

Zalo / phone: 0337 519 236 — support hours 8:00–21:00 daily.
Email: mr.nhattieulang@gmail.com — received 24/7.
24/7 AI Assistant: a support button in the corner of the screen on every page, answering immediately about usage, pricing, and policies, and handing off to Zalo when you need a human agent.

Handling procedure

Step 1 — The customer submits a request: account email, order code (format DN…), a description of the issue, and a screenshot or transfer receipt (if any).
Step 2 — We confirm receipt and give the expected resolution time.
Step 3 — Check and reconcile: wallet history, bank statements, system logs, order status, and product access rights.
Step 4 — Notify the result and solution: manual activation, wallet credit, compensation of credits or days, bug fix, or link reissue.
Step 5 — If the customer disagrees with the result, they reply for a second review. If the parties cannot resolve it themselves, they may ask the competent state management authority (the Department of Industry and Trade where the business is headquartered, the online.gov.vn system) to help resolve it, mediate, or file a lawsuit in court as provided by law.

Timeframes: initial response no later than 1 business day after receiving the request. Expected resolution time by type of issue:

Paid and clicked “I have transferred” but the wallet has not been credited, the plan has not been activated, or the product link has not appeared: during business hours, no later than 12 hours; wrong transfer description: within 1 business day.
Action failed but credits or wallet funds were still deducted: refunded within 1 business day.
Digital product link inaccessible or product does not match its description: fixed or reissued within 3 business days (Section 11).
Feature or display errors: expected 3 business days; errors caused by third-party data sources may take longer, and we will update the customer on progress.
Personal data requests (view, edit, delete, restrict processing, withdraw consent): within 7 business days.
Other complaints: expected within no more than 15 business days.

Resolution support tools: a unique order code for each transaction; wallet and transaction history in the account, exportable to Excel; reconciliation with bank statements; system logs recording each wallet deduction; an AI assistant for instant policy lookup.

5. Pricing policy

Prices are listed in Vietnamese dong (VND) and are the final amount the customer pays, inclusive of taxes (if any). Products and services are delivered online, so there are no shipping fees; we do not charge any surcharge beyond the listed price. Fees charged by the customer’s bank (if any) are borne by the customer.
Prices are listed on Pricing, the Top-up box, the Plans page, and each product’s detail page at /san-pham.
Pay-per-credit wallet: the cost of each action is clearly shown before the customer clicks run and is deducted only when the customer runs that action.
Strikethrough prices (if any) are the regular selling price before promotions are applied. Discount codes and top-up bonuses are calculated and shown before the customer pays.
When prices change, we update the listing pages before the change takes effect. Paid orders keep the price at the time of payment; topped-up wallet balances keep their value.
Fees charged to sellers: not applicable, as the platform has no other sellers. The reseller plan price list (for partners reselling the service) is published on Become a reseller: Startup 500,000 VND / year, Professional 1,499,000 VND / year, Business 4,999,000 VND / year; the entire plan amount is credited to the reseller wallet.

6. Conditions or restrictions on providing goods and services

Time: the platform operates 24/7, except during maintenance. Support staff review and approve bank-transfer order activations during 8:00–21:00 daily, no later than 12 hours after the customer clicks “I have transferred”; orders are not activated automatically.
Geography: no restriction on where the service can be used. VietQR transfer payment requires an account at a bank in Vietnam. Some data sources (depending on the source platform’s country) may be restricted or change beyond our control.
Eligibility: users aged 16 and over; one account per person; accounts locked for violations may not continue purchasing. Reseller plans apply only to organizations and individuals who register and are approved by DeepNiche.

New accounts receive 2 trial credits at sign-up, and each device / network can claim trial credits for only a limited number of accounts. Each digital product purchase grants usage rights for 1 account. Each discount code has a limit on total uses, uses per account, and an expiry date shown with the code.
Availability conditions: the service may be temporarily interrupted during maintenance, technical incidents, when third-party data sources (source platforms, AI providers) or platforms running digital products (Gemini, ChatGPT, Google Drive, Zalo) change, restrict, or discontinue provision, or due to force majeure. Failed actions are not deducted from credits.

7. Payment policy

Payment methods currently available:

Bank transfer via VietQR code to Vietcombank account · 0161001754415, account holder LE VAN VINH PHUOC. The customer scans the code, keeps the amount unchanged, and enters the correct description (account code and order code, format DN00012 DH000045), then clicks “I have transferred”. DeepNiche reconciles and manually approves to credit the wallet / activate the plan / deliver the product during business hours, no later than 12 hours.
Payment from your DeepNiche wallet balance for each data-fetching and analysis action; the cost is shown before running.
Wrong description or wrong amount: contact support with a photo of the receipt for reconciliation and manual activation (Section 4); excess transferred amounts are credited to the wallet.
When new payment methods are added (international cards, e-wallets…), we will update these Regulations before they take effect.

Refunds: DeepNiche does not offer refunds. Prepaid plans and wallet top-ups are non-refundable; failed actions are not deducted from credits. For details, see Section 11 and Section 13.

Bonuses and convertible offers:

Tiered top-up bonus (when applicable, listed in the Top-up box): the bonus is added to the wallet as soon as the top-up order is confirmed and can be used like wallet funds for all features; it cannot be withdrawn, refunded, or converted to cash. Both top-up funds and bonuses never expire.
Discount codes: a % or fixed-amount reduction on the order, with limits on total uses, uses per account, and expiry date; the discounted price is shown before payment; not convertible to cash.
Referral commission (affiliate program): referrers receive a lifetime 15% commission on every plan purchase or wallet top-up by the people they refer; withdrawals to a bank account start from 100,000 VND, with DeepNiche transferring manually. Details at Affiliate Policy.
Responsibilities of the parties: we calculate and credit top-up bonuses and referral commissions and show balances in your account; customers must not create fake accounts or refer themselves. Bonuses and commissions obtained through fraud are revoked.

8. Display priority policy

The product listing at /san-pham is displayed in an order arranged by DeepNiche (new products, flagship products). The “Featured” label is applied by DeepNiche to products it wants to highlight.
Search: results include products whose name, description, or features match the keyword the customer enters.
Customers choose their own criteria: filter by product type (AI Skills, AI Assistants, Courses…), filter free or featured products, and sort by price ascending or descending, right on the listing page.
We do not accept payment from third parties for display priority and do not rank products by individual customers’ search or transaction history.
Results from analysis tools (niche score, channel, video, and product rankings) are ordered by the data metric shown with the result (score, views, growth rate…); there are no paid positions.

9. Livestream selling regulations

The DeepNiche platform has no livestream selling feature, so this section does not apply. If a livestream feature is added, we will issue separate regulations and complete the amendment and supplementary notification procedures before rollout.

10. Delivery policy

We do not sell physical goods, so no shipping carrier is used. All products and services are delivered online to the customer’s account.
Wallet top-ups, monthly plans, annual plans, reseller plans: activated after DeepNiche confirms the funds have arrived, during business hours, no later than 12 hours after the customer clicks “I have transferred”.
Digital products (AI Skills, AI Assistants, apps): the product link appears immediately on the product page and is saved in the Products section of the account once payment is confirmed.
Courses: the class group link appears in the account after payment; the mentor contacts you for 1-on-1 activation within the timeframe stated on the course page.

Order information: order status is shown directly in the payment window and saved in the account’s wallet / product history.
Check upon receipt: the customer opens the link right after receiving it; if the link is broken or does not match the description, report it to support to have it reissued or fixed under Section 11.

11. Returns and refunds policy

DeepNiche does not offer refunds. Specific conditions:

Prepaid plans (Trial, monthly, annual, reseller plans) and wallet top-ups (including reseller wallets): non-refundable in all cases, including if the customer changes their mind or does not use the full plan term. Customers should use the 2 free credits at sign-up or the 7-day Trial plan before buying a larger plan.
Actions that fail due to the system or a data source returning no results: no credits or wallet funds are deducted, and no request is needed.
If a DeepNiche error leaves the customer unable to use the service for more than 24 consecutive hours: we compensate with credits or the affected days.
Digital products (AI Skills, AI Assistants, apps): because the content is delivered immediately, returns for change of mind do not apply. When the customer reports within 7 days of purchase and falls under one of these cases: (a) paid but did not receive the product; (b) the link is inaccessible or the product does not match the description on the sales page — we redeliver, reissue the link, or fix it within 3 business days of receiving the report.

Accounts locked for fraud or violation of the Terms of Use receive no compensation; bonuses, commissions, and promotional value obtained through fraud are revoked.

Process: the customer submits a request through the channels in Section 4, with the account email and order code → we check and confirm within 1 business day → credit the wallet, compensate credits or days, or reissue the product, and notify the customer.

Method: credited to the wallet or compensated as credits / days of use; no money is transferred back to bank accounts.

Costs: the customer pays no additional cost for handling.
