Terms of Service

1. Service

Trina Inc. ("we") provides Trina AX, a team AI workspace, as a cloud service.
The service uses generative AI. AI answers can be wrong; people should check important decisions.

A new team starts on the free plan: $0, no card. You get one free team per account and one per business registration number. Deleting a team does not give you a new free team.
We can change or end the free plan. We tell you at least 30 days before.
A free team has 5 GB data storage, 1 answer at a time and up to 3 people. Backups stay on the team server only; we make no off-site backup.
If a free team is not used for 14 days, we pause it. Choose "Resume" in the console to use it again. If it is not used for 90 days, we delete the team server and its data. We email you 30, 10 and 1 days before the deletion. A team that has paid at least once is only paused, never deleted automatically.
"Not used" means: no AI answer runs in the team, no new member is added, and no account owner or billing user logs in to the console. A team whose members only read answers can look unused.
A paid plan (Basic, Team, Pro) gives more memory, CPU, storage, answers at a time and people. To upgrade, you agree on the "Continue on a paid plan" screen showing the plan, first payment date, amount, payment method and how to cancel. We charge nothing without that agreement.
A team made on the 14-day trial before 31 October 2026 keeps the rules of that time: nothing is charged automatically when the trial ends; without an agreement the team is suspended, is canceled 7 days later and its data is deleted within 14 days after that.

Polar Software, Inc. (United States, "Polar") sells the paid plans to you as our online reseller and merchant of record. Polar takes the payment, adds the applicable tax (VAT or sales tax) and sends the invoices and receipts. At checkout you also agree to the Polar buyer terms (https://polar.sh/legal/checkout-buyer-terms).
Prices are in US dollars (USD), before tax: Starter $50, Team $100 and Business $200 per month. Polar adds the tax at checkout.
You pay the first month at checkout. Then the payment repeats every month from that day.
If a payment fails, Polar tries again and tells you by email. If the payment is not made within 14 days, the team is suspended (it opens again when the payment is made). 21 days later, the team is canceled.
An upgrade applies at once. Polar charges the difference for the days that are left at once. A downgrade applies from the next payment day.
A downgrade from a paid plan to the free plan ends the paid plan at the end of the current period. Then the team is on the free plan. It is not possible with more than 3 people, with more than 5 GB of storage in use, or when the account has or had its free team.
You do not need a business registration number to pay. Add it at checkout if you want it on your invoices.
A price increase does not apply to existing subscriptions.

You can cancel at any time in the console or in the Polar billing portal. The team runs to the end of the paid month. Then it is canceled.
Ask within 14 days of your first payment and we refund that payment in full. Later monthly payments are not refunded.
Duplicate charges and billing errors are always refunded. If we cannot provide the service for reasons on our side, we refund the days that we did not serve, pro rata.
Ask for a refund in the Polar billing portal, with the link in your receipt email, or by email to support with your order number. The refund goes back to the original payment method.

After cancellation we keep the data for 30 days and notify you 30, 7 and 1 days before deletion. You can export the whole team in the console meanwhile.
Then the team server, snapshots and backups are destroyed irrecoverably and we email a destruction confirmation. Payment and consent records are kept 5 years as the law requires.
A team canceled during the 14-day trial is kept for 14 days, not 30.
A free team deleted because it was not used (section 2) is deleted on the announced date, without the 30-day retention and without an automatic export. Before that date you can start the team again and export it in the console.
Team files and the primary database and its replica are stored on servers in the AWS Seoul region (ap-northeast-2). Encrypted off-site backups of teams on a paid plan or on the 14-day trial are kept in Cloudflare R2, whose location is not guaranteed (Asia-Pacific location hint). Content needed to produce AI answers is sent to the AI company the customer connects (United States).

Your AI company accounts (Anthropic, OpenAI, …) and compliance with their terms are your responsibility. API keys are the safest option.
Sharing one personal subscription (Claude Pro/Max, a ChatGPT plan) across a team may breach the AI company’s terms.

We keep no operator accounts on team servers and never log in as a customer.
Support access to team content needs your approval, a time limit, a second operator, recording and a notice to your team. Server administrators can technically bypass this; procedure and audit trails are how we prevent it, and we state that limit openly.

Monthly availability target per team: 99.5% (announced maintenance and AI provider outages excluded). Below target, on request: 10% credit (25% below 99%).
Short restarts may happen daily between 00:30 and 02:00 team time. Maintenance stopping the service over 5 minutes is announced 72 hours ahead.
The free plan costs $0, so it gets no credit.

Illegal use, infringing others’ rights, malware, abuse and phishing are prohibited and may lead to suspension.
Do not use the service as an electronic medical record or statutory archive.

Our liability for damage without intent or gross negligence is limited as far as the law allows.
These terms follow the laws of the Republic of Korea.
