You use Tally to get smarter, cheaper AI routing. We provide the service, protect your privacy, and never touch your actual LLM content. You own your data. We own our platform. Neither of us does anything shady with the other's stuff.
Read the full terms below for the specifics — they're not long.
By creating an account or using the Tally API, SDK, portal, or any related service (collectively, "the Service"), you agree to these Terms of Service. If you're using Tally on behalf of a company or organisation, you represent that you have authority to bind that entity to these terms.
If you don't agree to these terms, don't use the Service.
Tally is an AI routing layer. You integrate the Tally SDK into your application. The SDK computes a structural fingerprint ("semantic shape") of each LLM or MCP call — locally, within your application — and sends that shape to our API. We analyse patterns across shapes and return routing recommendations: which model is likely to give you the best result for the lowest cost on this type of call.
We do not proxy your LLM calls. Your application makes its own requests directly to model providers. Tally is advisory infrastructure, not middleware. See our Privacy Policy for what data we receive and what we never see.
You must create an account to use the Service. You're responsible for maintaining the security of your account credentials, including your Tally API keys. Don't share keys across teams or applications in ways you wouldn't want to grant full access — each key carries the permissions of the account that generated it.
You're responsible for all activity that occurs under your account, including usage by your team members or applications using your API keys.
We reserve the right to suspend or terminate accounts that violate these terms, abuse the Service, or engage in activity that harms other users or the platform.
You may use the Service for any lawful purpose, including commercial applications. You may not:
We may suspend access immediately and without notice for clear violations of these rules.
You own your data. The semantic shapes, telemetry, and routing outcomes associated with your account belong to you. We use this data to provide the Service — building your routing model, improving recommendation accuracy — and as described in our Privacy Policy.
We do not sell your data. We do not use your account's routing data to train models that compete with your applications. We may use aggregate, anonymized, non-identifiable data derived from all accounts to improve the shared cluster models that benefit all users.
When you close your account, we delete your data within 30 days as described in the Privacy Policy.
The Service, including the routing algorithms, shape analysis engine, API, SDK, portal, and documentation, is our property. These terms do not grant you ownership of any part of the Service. You receive a limited, non-exclusive, non-transferable license to use the Service as described here.
The Tally SDK is provided under an open-source license (see the SDK repository for details). That license governs your use of the SDK code itself. These Terms govern your use of the Service the SDK connects to.
Feedback you provide about the Service — suggestions, bug reports, ideas — may be used by us without obligation to you. We're not trying to steal your ideas; we just don't want a legal dispute if we independently build something you suggested.
Paid plans are billed in advance on a monthly or annual basis. Usage beyond your plan limits may result in overage charges as described on the Pricing page.
Payment is processed by Stripe. We do not store your payment card details. If payment fails, we'll notify you and provide a grace period before suspending access.
Refunds are available within 14 days of a new subscription if you haven't made significant use of the Service. For annual plans, we'll provide a prorated refund for unused months if you cancel within the first 60 days. After those windows, fees are non-refundable.
We may change pricing with 30 days notice for monthly subscribers and 60 days notice before renewal for annual subscribers. You can cancel before any price change takes effect.
We aim for high availability but do not guarantee uninterrupted service. The routing recommendation API is designed to fail gracefully — if Tally is unavailable, your application should fall back to a default model rather than failing entirely. The SDK is built with this in mind.
We'll provide advance notice of planned maintenance when possible and communicate outages through our status page at api.tallyy.org/health.
Tally provides routing recommendations. We are not responsible for the outputs, costs, quality, accuracy, or behaviour of any LLM or MCP provider you use. The routing decision you act on is always your application's decision.
To the maximum extent permitted by law, our total liability to you for any claim arising from your use of the Service is limited to the amount you paid us in the 3 months before the claim arose.
We are not liable for indirect, incidental, consequential, or punitive damages — including lost revenue, lost data, or business interruption — even if we had reason to know such damages were possible.
Nothing in these terms limits liability for death or personal injury caused by negligence, fraud, or anything else that cannot be legally excluded.
The Service is provided "as is" and "as available." We make no warranty that the Service will be error-free, that routing recommendations will achieve any particular cost savings or performance outcome, or that the Service will meet your specific requirements.
That said: we believe in what we've built. If Tally isn't working for you, contact us. We'll try to fix it.
You may cancel your account at any time through the portal. Cancellation stops future billing and triggers data deletion as described in the Privacy Policy.
We may suspend or terminate your access for violations of these terms, extended non-payment, or if we have reason to believe your use is causing harm to others or the platform. We'll provide notice where practical, except in cases of serious violation or abuse where immediate action is necessary.
On termination, your right to use the Service ends immediately. Provisions that should survive termination (data deletion, liability limits, dispute resolution) do survive.
We may update these terms. If we make material changes, we'll notify you by email at least 14 days before they take effect. If you continue using the Service after that date, you accept the new terms.
If you disagree with a change, you may cancel your account before it takes effect and receive a prorated refund for any prepaid period.
These terms are governed by the laws of the Province of Ontario, Canada, without regard to conflict of law principles. Any disputes will be resolved in the courts of Ontario unless we agree otherwise in writing.
If you're outside Canada, we're willing to discuss alternative dispute resolution. Reach out before starting any legal proceedings — most issues can be resolved with a conversation.
