Terms of Use

Zasu is a marketplace that connects learners with independent tutors and experts. Tutors and experts are not Zasu employees; they are responsible for the content and quality of their own lessons and consultations.

Zasu provides search, scheduling, video classrooms, a payment wallet, messaging and dispute resolution. Zasu does not promise any particular learning outcome or score.

You must provide truthful information and keep your password safe. All activity on your account is treated as yours.

Each person may hold only one account. Creating multiple accounts to abuse offers (trial lessons, promotions…) leads to a permanent ban.

People under 16 may use Zasu only with the consent of a parent or guardian, who should create and manage the account and is responsible for its transactions.

Learners pay for all lessons and packages from their Zasu wallet balance. Top up by bank transfer using the unique top-up code shown on the Top up page (20,000₫ to 50,000,000₫ per top-up; each code is valid for 60 minutes). Your wallet is credited with the amount actually received.

If a transfer has a wrong or missing code, contact support@izasu.com with the receipt so it can be reconciled and credited manually.

Wallet balances earn no interest and cannot be transferred to another account. Learners who want their unused balance back can click “Refund balance to bank” on the My lessons page (minimum 20,000₫); the amount is taken out of the wallet immediately and Zasu transfers it to a bank account in the Zasu account holder's name within about 7–10 business days after verification. The request can be cancelled until the transfer is made.

With each tutor a learner can take up to 2 free 15-minute trials (if the tutor offers them) and up to 2 paid 50-minute trials at a discounted price set by the tutor. Each learner has up to 5 free trials and 10 paid trials across all tutors; every package purchased adds 2 of each (remaining trials never exceed those numbers). Regular lessons last 50 minutes.

28-day cycle plans (4, 8 or 12 lessons per cycle) are charged at the full price and renew automatically from your wallet; you can turn auto-renewal off at any time. 24-, 48- and 96-lesson packages come with 3%, 5% and 10% discounts and are valid for 6, 12 and 24 months respectively.

When a package period ends without renewal, the learner has a 28-day grace period to keep booking, renew (unused lessons carry over) or cancel for a refund. After the grace period, unused lessons are forfeited and not refunded.

Cancelling a package refunds the unused lessons. For discounted packages, lessons already taken are recalculated at the full price and the difference is deducted from the refund.

Lesson payments are held by Zasu and released to the tutor's wallet only when the lesson is completed. The platform takes a 15% commission on regular lessons and 50% on paid trials; free trials carry no fee.

A lesson is confirmed as completed when the learner presses “Confirm lesson completed” after the end time, or automatically 24 hours after the lesson ends if the learner has not opened a dispute (the system decides from classroom attendance). During these 24 hours Zasu holds the fee; it is not yet paid to the tutor.

New-tutor welcome: Zasu waives the platform fee on regular lessons (one-to-one and group) held within the first 90 days from the first regular lesson, for tutors who had no regular lesson before the programme started. Paid trials and learner no-shows follow the standard rules. The programme may close once enough tutors have joined; tutors whose first regular lesson took place before then still get the full 90 days.

You can cancel or reschedule for free at least 8 hours before the lesson — the learner gets a 100% refund. In the last 8 hours neither side can cancel; you can only propose a new time, and the lesson moves only if the other side accepts.

Absences are decided from classroom attendance 24 hours after the lesson ends; during that time the learner can open a dispute. A learner with recorded classroom attendance cannot be marked absent.

Learner no-show (tutor present): no refund; the tutor receives 70% and the platform keeps 30% (paid trial lessons: 50% each, as for a lesson taught). Two no-shows in a row temporarily suspend free trials. Tutor no-show (learner present): the learner gets a 100% refund. Both absent with no dispute: no refund and no payment to the tutor.

If the tutor cancels, the learner is always refunded 100%. Tutor cancellations, tutor no-shows and lessons where both sides are absent all count against the tutor; repeated faults lower the tutor's ranking and can get the profile suspended.

You confirm that your profile, degrees, certificates and experience are truthful. Zasu may ask for documents to verify them; your profile and changes to public content appear only after Zasu approves them.

When reviewing, Zasu may edit the presentation of your profile (spelling, capitalisation, completing your full name as on your ID, removing off-platform contact details, removing an unsuitable photo) before publishing and will tell you which items were edited; you remain responsible for the professional content. You can edit it again at any time (subject to review as usual).

Lesson earnings are credited to your Zasu wallet once a lesson is completed. You can request a withdrawal when your balance is at least 500,000₫, with a minimum of 100,000₫ per request and one pending request at a time. Zasu transfers the money to the bank account in your name given in your profile, usually within about 7–10 business days.

You are responsible for declaring and settling the taxes on your income with the tax authority under the laws of your country of residence. Where a competent authority so requires, Zasu will withhold, declare or provide information in accordance with that requirement and let you know.

Search ranking, badges and levels depend on teaching quality, learner reviews and schedule reliability. Zasu may hide, suspend or remove profiles that breach these Terms.

All lessons and payments between learners and tutors must go through Zasu. Sharing contact details (phone, email, social media…) to arrange lessons or payments outside the platform breaches these Terms and can lead to account suspension.

Messages containing contact details are blocked automatically and may be reviewed by an administrator.

False profile information, fake reviews, harassment, discrimination, sexual or violent content, and anything unlawful are prohibited. Zasu may remove such content and suspend the accounts involved.

You are responsible for the materials you upload or share in lessons and must have the right to use them. Files shared in lessons are deleted automatically after 7 days.

The Zasu website, app, software, interface, name and logo, and the content on the platform (including tutor and expert profiles, reviews and prices) belong to Zasu or to the person who posted them. Using robots, automated data-collection tools (scrapers, crawlers) or any other means to copy or extract data in bulk; copying, modifying or reverse-engineering the software; or reusing the content for commercial purposes without Zasu's written consent is prohibited. Search engines may index public pages as allowed by robots.txt. Zasu may limit or block access, suspend accounts and claim damages for violations.

Zasu works to keep the service stable but does not guarantee it will be uninterrupted or error-free. If a technical problem on Zasu's side prevents a lesson from taking place, the learner is refunded for that lesson.

To the extent permitted by law, Zasu's liability for any lesson does not exceed the amount the learner paid for that lesson.

Zasu may update these Terms when the service changes or when the law requires it. Significant changes will be announced in the app or by email at least 7 days before they take effect. Continuing to use Zasu after that date means you accept the updated Terms.

These Terms are governed by the laws of Vietnam. Disputes between learners and tutors are handled first through Zasu's dispute process. Disputes with Zasu will first be settled by negotiation; failing that, either party may bring the matter before a competent court in Vietnam.

A group class is a video class of 2–5 learners with one tutor on a fixed weekly schedule. Learners pay per session pack (ongoing classes) or buy a whole course at once (full courses). Zasu holds the payment and releases it to the tutor, net of commission, session by session after the 24-hour dispute window.

A missed session still counts. Leaving a class mid-way is not refunded, except in these cases where unused sessions are refunded to the wallet: the class lacks its minimum number of learners 24 hours before the first session, the class is closed, the learner is removed by the tutor or Zasu, the class is paused for 2 weeks or more, or the tutor cancels or no-shows 3 or more sessions within one pack. Up to 8 hours before the first session a learner may withdraw with a 100% refund. Full courses carry a first-two-sessions guarantee: leaving within 24 hours after session 2 ends refunds the remainder, with the two sessions taken charged at the single-session price.

When the tutor does not teach a session for any reason (cancellation, no-show, time off, pause, public holiday, cancellation by Zasu) that session is not deducted from learners' packs and rolls over; Zasu does not refund that session to wallets. Tutor cancellations and no-shows receive fault marks on an 8-hour scale (0.5 / 1 / 1.5 faults) with the consequences described in the ranking section. Group sessions cannot be rescheduled.

A tutor may run at most 3 classes at a time and every class must be approved by Zasu. Zasu may hide, pause or close a class that breaches the rules, in which case learners are refunded their unused sessions. A dispute about a group session can be opened within 24 hours after it ends and only affects the disputing learner's share.
