Terms of Service

Draft — not legal advice; final text pending review.

Draft, last changed 8 September 2026

These terms govern your use of the Subtl applications and the subtl.me service, provided by Arcada US LLC.

They are written to be read. Where a clause limits what you may do or what we owe you, it says so in plain words rather than hiding in a paragraph of definitions.

1. What the service does

Subtl transcribes speech, translates it, and drafts possible replies on your device during a call. Capture is performed by the application running on your machine, under your control, from audio your device is already playing and from your microphone.

You are the operator of that capture. We provide the tools that process what your device gives us.

2. Your responsibility for the other participants

Laws about recording, intercepting and processing a conversation differ by country and, in the United States, by state. Some require the consent of every participant.

Notifying the people you are speaking with, where the applicable rules require it, is your responsibility and not ours. Subtl does not record audio by default and does not store audio on its servers, but that does not by itself make any particular use lawful where you are.

3. AI output is a draft

Transcriptions, translations and suggested replies are produced by machine-learning models and can be wrong, incomplete or misleading. We make no claim of perfect accuracy in any language.

The output is informational. It is not legal, medical, financial or immigration advice, and the decision about what you say remains yours.

4. Where you may not use Subtl

You warrant that your use complies with the rules of any platform, examination body, employer or counterparty that binds you. Where assistance is prohibited — for example in an examination, a certification, or an interview whose rules forbid it — you may not use Subtl.

5. Subscriptions and payment

Subscriptions renew automatically until cancelled. You may cancel at any time and keep access until the end of the period you have paid for.

All payments are final and non-refundable, except where required by applicable law. Consumers in the EU and the UK have a statutory 14-day right of withdrawal for digital content, which is waived only where you explicitly consent at checkout to immediate access and to losing that right. Purchases made through the Apple App Store or Google Play are refunded, if at all, under those stores' own rules.

Payments are processed by Stripe. Taxes are calculated at checkout by Stripe Tax.

6. Limits

  • Minutes per billing period, as stated by your plan.
  • Up to five devices per account and two concurrent sessions.
  • Unlimited plans are subject to fair use, capped at 100 hours per month.
  • Automated or shared use of a single account is not permitted.

7. Bringing your own AI key

On the plan that uses your own provider key, that key is stored in your system keychain. In proxy mode it passes through our server in memory and is not logged or stored.

You remain bound by the terms of the provider whose key you use, and you pay them directly.

8. Changing the price

We may change prices with at least 30 days' notice. The price you are paying continues until the end of the period you have already paid for.

9. Liability and governing law

To the extent the law allows, our liability is limited to the amount you paid us in the twelve months before the event giving rise to the claim.

These terms are governed by the law of the state in which Arcada US LLC is registered, with disputes resolved there. Consumers in the EU keep the mandatory protections of the country in which they live, and nothing here removes them.
