Terms of Use

Blaine · Last updated: October 2026

These terms cover your use of Blaine ("the app", "the service"). By creating an account or using the app, you agree to them. If you do not agree, please do not use the service.

Your account

• You must be at least 13 years old to use Blaine.
• You are responsible for what happens under your account, and for keeping your sign-in details secure.
• Give accurate account information, and keep it up to date.
• You may delete your account at any time from Settings → Delete Account.

Subscriptions and billing

• Paid plans are billed in advance on a recurring basis until cancelled.
• You can cancel at any time. Cancelling stops future charges; your plan stays active until the end of the period you have already paid for.
• Plans are subject to fair-use limits. If you consistently exceed them we will contact you before taking any action.
• Prices may change. We will tell you before a change affects you, and you can cancel if you do not want to continue.
• Where a purchase is made through an app store, that store's refund and cancellation rules also apply.

What you may not do

• Break the law, infringe someone's rights, or help anyone else do either.
• Use the service to create or spread content that harasses, defrauds, or endangers people.
• Attempt to breach, overload, reverse-engineer, or circumvent limits on the service.
• Resell or redistribute the service, or use it to build a competing product.
• Use automated means to extract the service's outputs at scale.
• Scrape, crawl, or copy the service, its interface, or its content by automated or manual means.
• Reverse engineer, decompile, or otherwise try to derive the service's source code, prompts, checking algorithm, or prompt breakdown process.
• Copy or imitate the Blaine interface design, the Blaine logo, the claim marks (✓ Supported, ✎ Corrected, ? Disputed, — Unconfirmed), or the claim-marking process.
• Use the service or its outputs to train, build, or improve a competing product or service.

Intellectual property

Blaine™, Blaine.chat™, the Blaine logo, and the Blaine claim marks (✓ Supported, ✎ Corrected, ? Disputed, — Unconfirmed) and their visual design are trademarks of Blaine.chat. Use of the Blaine logo without written permission is prohibited. The Blaine interface design, claim-marking system, prompt breakdown process, and determinism-first checking algorithm are proprietary. Copying, scraping, reverse engineering, or reproducing them without written permission is prohibited.

Your content

You keep ownership of everything you put into Blaine and everything it produces for you. You give us only the permission we need to run the service for you — to store, process and transmit your content so the app can do what you asked. We do not sell your content and we do not use it to train our own models.

Accuracy, and its limits

Blaine checks its answers before showing them to you, and tells you what it was able to establish about each claim. That checking is the point of the product and we take it seriously — but no system of this kind is infallible, and Blaine can still be wrong.

Blaine's answers are information, not professional advice. Do not rely on them alone for medical, legal, financial, or safety-critical decisions. Where the stakes are high, verify independently before acting.

Availability

We aim to keep the service running and improving, but we do not guarantee it will be uninterrupted or error-free. We may change, suspend, or discontinue features. If we discontinue the service entirely, we will give you reasonable notice and a way to export your data.

Ending your access

You may stop using Blaine and delete your account at any time. We may suspend or close an account that breaches these terms, or where we are required to by law. Where circumstances reasonably allow, we will tell you why and give you a chance to put it right.

Liability

To the extent the law allows, Blaine is provided "as is", and we are not liable for indirect or consequential losses, or for loss of profits or data, arising from your use of the service. Nothing in these terms limits liability that cannot be limited by law — including for death or personal injury caused by negligence, or for fraud. Some jurisdictions do not allow certain exclusions, so parts of this section may not apply to you.

Nothing here affects the statutory rights you have as a consumer.

Changes to these terms

We may update these terms from time to time. Material changes will be reflected by the "Last updated" date above, and we will give notice where the change meaningfully affects you. Continuing to use the service after a change means you accept it.
