About these terms
In these terms, “we”, “us”, and “our” refer to Tacendo. Questions or complaints can be sent to help@tacendo.com.
These terms apply when you use Tacendo. Read our Privacy policy for how we handle personal information and the payment and refund terms below before buying credits.
Your account
You must be legally able to enter into this agreement and, if using Tacendo for an organisation, have authority to act for it. Tacendo is not directed at children.
Sign-in uses an existing Solana wallet: you sign a sign-in message with it, connected directly or through WalletConnect. Protect your wallet, device, passkeys, and recovery key. Do not share access or use another person’s account without permission. We never need your wallet seed phrase or private key.
Chat history saved on a device can be lost if you clear site data or lose the device. Synced history requires a working passkey or recovery key; we cannot decrypt it for you if you lose both.
Acceptable use
Use Tacendo lawfully and respect other people’s rights. You must not:
- Upload content you are not authorised to share, including personal information or copyrighted material.
- Use the service for fraud, exploitation, unlawful harassment, or illegal content, including child sexual abuse material.
- Attack the service, bypass authentication or billing, interfere with other users, or extract their data.
- Use AI responses to make consequential decisions about people without appropriate human review and a lawful basis.
Relevant model and provider restrictions also apply. Contact us if you need clarification about a proposed use.
AI responses
You are interacting with AI. Responses can be inaccurate, incomplete, biased, or unsuitable, even when they sound confident. Check important information before relying on it or sharing it.
Tacendo does not provide professional medical, legal, financial, or other regulated advice. Get appropriate qualified advice for decisions that affect health, rights, finances, or safety.
We do not guarantee that responses are unique, copyrightable, or free of third-party rights. You remain responsible for how you use them.
Content & privacy
You retain any rights you already have in your inputs. You permit us and the providers involved in your request to process that content as needed to operate the service and generate a response, as described in the Privacy policy.
Stored chat history is encrypted in your browser. Messages and attachments sent for inference pass through our server in readable form and are forwarded to the configured inference provider. Tacendo does not provide end-to-end encryption for inference or client-side attestation verification.
Incognito models run outside a trusted execution environment and send the conversation and attachments to an upstream model provider. Review the model’s privacy label before sending sensitive information. Our Security docs explain these limits.
Credits & payments
Tacendo uses prepaid USD-denominated usage credits rather than a recurring subscription. Model prices are shown in the selector and can change for future requests. Charges depend on input and output tokens, including conversation context and generated reasoning where applicable.
The payment screen shows the accepted asset and network. The current mainnet flow credits $1 per accepted USDC or USDT unit, with a $1 minimum and $1,000 maximum per top-up. Your wallet charges a separate network fee in SOL. Check the asset, network, amount, and destination before approving; stablecoin market values can differ from their intended dollar value. Testnet transfers are for testing and are not real-money purchases.
Credits are linked to your account, are not transferable through the app, and do not currently expire automatically. They pay for Tacendo usage and are not a bank account or investment.
Before inference, we reserve credit for the request. When reported usage is available, the charge replaces the reservation and unused reserved credit is released. The price recorded at the start of the request applies to that request. Inputs can include earlier messages and attachments; outputs can include reasoning.
Stopped or interrupted replies, or replies with missing usage reports, can be charged using an estimate. A server failure that leaves a request unsettled for more than ten minutes currently results in the full reservation being charged. A failure before output is generated normally releases the reservation when handled by the server. Contact us to dispute an incorrect charge; these technical fallbacks do not remove your legal rights.
Credit is added after a qualifying transfer is verified. If a transfer was sent but not registered, use the payment screen’s retry action rather than paying again. Confirmed blockchain transfers cannot be cancelled, and transfers using unsupported assets or networks may not be recoverable.
Refunds & billing problems
For missing credit, incorrect charges, accidental payments, or a refund request for unused credits, contact help@tacendo.com with the transaction signature, wallet address, network, asset, approximate time, and a description of the problem. Do not send private keys, seed phrases, or chat content.
Refunds and corrections are handled through support; there is no automatic refund or cash-out function. We assess requests on their circumstances and applicable consumer law. A change of mind does not by itself create a statutory refund entitlement, but you can ask us to review your request.
Any agreed refund method and amount will be confirmed with you after account and transaction verification. A refund is a separate payment, not a reversal of the original blockchain record.
We do not apply a blanket “no refunds” rule to statutory remedies. An AI accuracy notice, a billing estimate, or blockchain irreversibility does not remove mandatory consumer protections.
Availability & suspension
Models and features can change or become unavailable, and providers may reject requests. We may restrict access where reasonably necessary to address misuse, security risks, or legal obligations. Contact us if you believe a restriction was made in error.
You can stop using Tacendo at any time. For account closure, privacy requests, or questions about unused credits, contact help@tacendo.com. Signing out does not delete your account or saved chats.
Your legal rights
Nothing in these terms excludes, restricts, or modifies rights or remedies that cannot lawfully be excluded.
Subject to those rights, we do not promise uninterrupted availability or that every AI response will meet your needs. Responsibility for a loss depends on the circumstances and applicable law; these terms do not impose a blanket waiver of our legal obligations.
Contact help@tacendo.com first so we can try to resolve a concern.
Changes to these terms
We will update the date on this page when the terms change and give reasonable notice of material changes through the service. Where the law requires agreement to a change, we will seek it. Changes do not remove rights relating to earlier purchases or disputes.
