Terms of Service

Last updated: November 12, 2026

These terms apply when you use Harntung ("Harntung", "we", "us"): the website at www.harntung.com, the Harntung LINE account, and the Harntung app for Clover. By using Harntung you agree to these terms and to our Privacy Policy. If you don't agree, please don't use Harntung.

1. What Harntung does

Harntung helps groups split bills. You create a bill, add the people and the items, and Harntung works out who owes whom. You can also scan a receipt to fill in the items, share a payment QR code (such as PromptPay), and open a bill from the QR code on a participating restaurant's receipt.

Harntung only does the maths. We don't hold, send, or receive money between the people on a bill, and we aren't part of any payment they make to each other or to a restaurant.

2. Shared bills

• Anyone who has a bill's link can open it and edit its people, items, and payments. Only share a link with people you trust, and don't put anything on a bill that you wouldn't want them to see.
• If you are signed in when you create a bill, you are its owner. Only the owner can rename, lock, or delete it. A bill created without signing in has no owner.
• You are responsible for what you put on a bill, including names and payment details such as a PromptPay number. Only add other people's details with their permission.
• Check the amounts before anyone pays. We work hard to get the calculations right, but we can't promise they are free of errors, and we aren't responsible for money paid or owed between users.

3. Accounts

You can create, open and edit bills without an account. New bills are limited per calendar month (Thailand time): 2 on a device without signing in, 4 on a free account signed in with Google, and no limit with Harntung Pro. Receipt scanning and purchases need you to sign in with Google. Keep your Google account secure: anything done while signed in to it is treated as done by you.

4. Receipt scanning

Receipt scanning reads a photo of a receipt and suggests items and prices. It can make mistakes, so please review the results. Each scan uses one credit or one scan from your Harntung Pro monthly allowance. You are only charged for a scan that succeeds.

5. Credits and Harntung Pro

Payments are processed by Stripe. Prices are shown before you pay, and the price at checkout is the one you'll be charged.

• Credits are used for receipt scans. They have no cash value, can't be exchanged or transferred, and are non-refundable. If we stop offering receipt scanning, unused credits are not refunded.
• Harntung Pro yearly subscription renews automatically every year until you cancel. You can cancel at any time from the "Manage subscription" option in Harntung, which opens Stripe's billing page. When you cancel, you keep Pro until the end of the year you've already paid for, and you won't be charged again.
• Harntung Pro 1-year pass is a one-time payment for one year of Pro. It does not renew.
• Payments for Pro are non-refundable, including for unused time, except where the law requires a refund. If you were charged twice for the same period of Pro, contact us and we'll refund the duplicate.

We may change prices or what's included in Pro. A price change won't affect a period you have already paid for.

6. Harntung for Clover

If you are a business that installs the Harntung app from the Clover App Market:

• You allow Harntung to read your business name and the orders whose receipt QR codes your guests scan, as described in our Privacy Policy.
• The QR code on your receipts lets guests open a shared bill containing that order's items and prices. Bills your guests create stay available to them after you uninstall.
• Harntung doesn't change your orders, take payments, or affect how you get paid. Guests still pay you as they normally do.
• Clover controls when receipt QR codes start and stop appearing. It can take several hours after you install or uninstall.

7. Acceptable use

Please don't:

• Use Harntung for anything illegal, fraudulent, or to harass anyone
• Try to access bills, accounts, or data you aren't meant to, or disrupt or overload the service
• Scrape, copy, or resell the service, or use it to build a competing product
• Abuse free credits, promotions, or the scan allowance

We may suspend or close access, or remove credits obtained through abuse, if these terms are broken.

8. Advertising

Harntung shows ads from Google and affiliate links from partners such as Trip.com and Shopee, which may pay us a commission when you book or buy. Advertisers and partners are responsible for their own ads, websites, and services.

9. Our content

Harntung's name, logo, design, and software belong to us. You may use Harntung for its intended purpose, but you may not copy, modify, or redistribute it. You may link to Harntung, but you may not show Harntung inside a frame on another website unless we agree to it, as we have with Clover for its digital receipts.

10. Disclaimer and limitation of liability

Harntung is provided "as is". We don't promise it will always be available, error-free, or suitable for a particular purpose.

To the extent the law allows, we are not liable for indirect or consequential losses, or for disagreements or money owed between users. Our total liability to you is limited to the amount you paid us in the 12 months before the claim. Nothing in these terms limits liability that the law doesn't allow us to limit, such as for fraud.

11. Changes

We may update Harntung and these terms. When we make an important change, we'll update the date above and, where appropriate, tell you in the app. If you keep using Harntung after a change, the new terms apply.

12. Governing law

These terms are governed by the laws of Thailand. This doesn't take away any rights you have under the consumer laws of the country you live in.
