Terms of Service

1. The Service and who may use it

TokenCalculator is an online token-cost calculator for LLM APIs. You paste prompts, set usage assumptions, and compare estimated cost across models and providers. We also publish a machine-readable price feed at /api/prices.json.

You must be at least 13 years old (16 in the EEA and the UK) and able to form a binding contract where you live. If you use the Service on behalf of an organisation, you confirm you are authorised to bind it to these Terms.

You are responsible for your credentials and for everything that happens under your account. Email hello@tokencalculator.com promptly if you suspect unauthorised access.

2. Plans, billing and cancellation

The Free plan is free for as long as you use it, within its published limits. Paid plans are billed in advance through Stripe; we never receive or store your full card details.

Subscriptions renew automatically at the then-current price until you cancel. You can cancel at any time from Account → Billing, and your paid access continues until the end of the period you have already paid for.

We may change prices or plan limits. We will give you at least 30 days’ notice before a change applies to your renewal; continuing to use a paid plan after that means you accept the new price.

Except where the law requires otherwise, payments are non-refundable, including for partial billing periods. If a renewal payment fails and is not resolved, your account may be downgraded to the Free plan.

3. Your content

You keep every right you already have in what you paste into the calculator. We claim no ownership of your prompts or input text.

You grant us a limited, worldwide, royalty-free licence to host, store, back up, transmit and display your content solely in order to operate the Service for you — and, where you ask for help or we investigate abuse, to review it to the minimum extent needed. The licence ends when you delete the content or your account.

We run backups, but they are not a substitute for your own. Export your data regularly.

4. Pricing data and AI features

Pricing data is sourced from each provider’s official pricing page and re-verified on a regular cadence. Provider prices change without notice — the “Updated YYYY-MM-DD” stamp on each card reflects the last verification, and /api/prices.json reflects the same.

Where applicable, AI-assisted features (if any) produce output via statistical models. Treat AI output as a draft suggestion — not as advice, and not as a guarantee of accuracy.

Do not use the Service to generate unlawful, infringing, deceptive or harmful material.

5. Acceptable use

When using the Service, you agree not to:

• upload or generate content that is unlawful, infringing, defamatory, or sexually exploitative of minors;
• share one account among multiple people, or resell or sublicense the Service;
• scrape, crawl or bulk-download the Service, or bypass rate limits, quotas or plan restrictions;
• reverse-engineer, probe or attack the Service, or attempt to access data that is not yours;
• upload malware, or use the Service to send spam or to impersonate others.

6. Disclaimers and limitation of liability

The Service is provided “as is” and “as available”. We do not warrant that it will be uninterrupted, error-free, or that pricing estimates will match your bill exactly. To the fullest extent permitted by law, we disclaim implied warranties of merchantability, fitness for a particular purpose and non-infringement.

To the maximum extent permitted by law, we are not liable for indirect, incidental, special or consequential damages, or for lost profits, lost data or lost goodwill. Our total aggregate liability for any claim is limited to the greater of US$100 or the amount you paid us in the 12 months before the claim arose.

Some jurisdictions do not allow these exclusions, so parts of this section may not apply to you.

7. Termination, changes and governing law

You may stop using the Service at any time and delete your account from Account settings; deletion removes your saved inputs as described in the Privacy Policy.

We may suspend or terminate an account that breaches these Terms or creates legal or security risk, with notice where that is practical.

We may update these Terms. For material changes we will notify you by email or in the app before they take effect, and we will always update the date at the top of this page.

These Terms are governed by the laws of the State of Delaware, USA, without regard to its conflict-of-laws rules. Before filing a claim, both sides agree to try to resolve the dispute informally by email for 30 days. If that fails, disputes will be resolved by binding individual arbitration administered by the American Arbitration Association under its Consumer Arbitration Rules, seated in Delaware — not in a class or representative action. Either side may still bring a qualifying claim in small-claims court. You may opt out of arbitration within 30 days of first accepting these Terms by emailing us.
