Terms of Service
Last updated: April 2026 — Version 2 (BYOK subscription model, draft pending counsel review)
1. Service Description
HiWay2LLM ("the Service") is an intelligent LLM routing proxy operated by Mytm-Group SAS ("the Company"), a French company registered in France. The Service analyses chat-completions API requests and routes them to the optimal Large Language Model (LLM) provider based on request complexity, reducing costs while maintaining output quality.
The Service operates on a Bring-Your-Own-Key (BYOK) model: the Client provides the Company with their own API credentials for the LLM Providers they wish to use (Anthropic, OpenAI, Google, Mistral, DeepSeek, and others). The Company does not provide LLM inference directly and does not purchase, resell, or relay inference resources in its own name.
2. Account and API Keys
2.1. To use the Service, Clients must create an account with a valid email address and password. Each account receives a unique HiWay API key (prefix hw_live_) used to authenticate calls to the Service.
2.2. HiWay API keys are shown once at creation. The Company stores only cryptographic hashes (SHA-256) of HiWay API keys. Lost keys cannot be recovered — they must be revoked and regenerated.
2.3. BYOK provider keys (Anthropic, OpenAI, Google, Mistral, DeepSeek) supplied by the Client are encrypted at rest by the Company using AES-256-GCM with a per-workspace key derivation (HKDF) and authenticated additional data. The Company is technically unable to decrypt BYOK keys outside the request path. The Client remains the sole holder of the master credentials with each LLM Provider.
2.4. Clients are solely responsible for the security of their HiWay API keys and of their BYOK provider keys. Any usage routed through a Client's HiWay API key and charged to a BYOK provider key is the Client's responsibility. The Company is not liable for losses resulting from unauthorised use of Client keys, whether HiWay or BYOK.
2.5. The Company reserves the right to suspend or terminate accounts that violate these Terms, engage in fraudulent activity, or abuse the Service, as detailed in Sections 7 and 8.
3. Subscription, Plans and Billing
Contractual structure — summary
The Client subscribes to a monthly (or annual) plan that grants access to the HiWay2LLM routing intelligence. Inference is billed by the LLM Providers directly to the Client on the Client's own provider accounts. The Company applies zero markup on inference and receives no inference fees — only subscription fees constitute Company revenue and fall within the scope of French VAT.
3.1. BYOK model. The Service operates on a Bring-Your-Own-Key basis. The Client provides API credentials for the LLM Providers they wish to use, which the Company stores encrypted (Section 2.3) and uses solely to forward the Client's requests to the designated Provider. Each LLM Provider bills the Client directly on the Client's own provider account, under the Provider's terms of service. The Company does not receive, hold, pass through, or otherwise touch the funds paid by the Client to the LLM Providers.
3.2. Plans. The Client subscribes to a plan granting access to the Service (routing engine, dashboard, burn-rate alerting, anti-abuse systems, support). Plan tiers as of the date of these Terms are:
- Free — €0/mo — 10,000 routed requests per month — no credit card required;
- Build — €12/mo (or €115.20/yr) — 100,000 routed requests per month;
- Scale — €49/mo (or €470.40/yr) — 1,000,000 routed requests per month;
- Business — €299/mo (or €2,868/yr) — 6,000,000 routed requests per month;
- Enterprise — on request — custom quotas, SSO, audit log, DPA.
Current plans, quotas and prices are displayed in the Client dashboard and may be adjusted with 30 days advance notice. Quota overages on paid plans are soft-capped (routing continues with reduced priority and the Client is invited to upgrade); the Free tier is hard-capped at its monthly quota.
3.3. Payment processing. Subscription fees are processed by Stripe, Inc., under Stripe's own terms of service. The Company does not store credit card numbers. Payments are debited monthly (or annually, if the annual plan is selected) on the recurring date of the first billed cycle. The Client can update or cancel the subscription at any time from the dashboard; cancellation takes effect at the end of the current billing cycle.
3.4. VAT treatment. All subscription fees are invoiced by Mytm-Group SAS and subject to French VAT at the standard rate of 20%, or to the reverse-charge mechanism of Article 283-2 of the French General Tax Code for business Clients established in another EU Member State, or to the exemption of Article 259 B of the French General Tax Code for business Clients established outside the European Union, as applicable. The invoice shows the plan, billing period, applicable VAT rate and total.
3.5. Zero markup on inference. The Company applies no markup on inference. All inference charges flow from the LLM Provider directly to the Client, under the Provider's terms and at the Provider's published prices. The Company has no visibility on Provider invoices beyond what the Client chooses to share (e.g. for support purposes).
3.6. Refund of unused subscription. Subscription fees are non-refundable except where expressly provided (Section 5.4 service unavailability, Section 8.3 termination by the Company for convenience). In those cases, the unused pro-rata portion of a prepaid annual subscription is refunded to the original payment method within 30 days.
3.7. Price adjustment. The Company reserves the right to adjust plan prices or quotas with 30 days advance notice to existing Clients. Prices already invoiced for the current billing cycle are not retroactively affected.
4. Regulatory Position
4.1. SaaS qualification. The Service is a software-as-a-service (SaaS) offering providing routing intelligence for LLM API calls. The Company sells access to its routing software under a monthly or annual subscription, taxed as an electronically supplied service under standard French VAT rules.
4.2. No funds held on the Client's behalf. Under the BYOK model described in Section 3, the Company does not hold Client funds, does not collect funds to be remitted to LLM Providers, and does not intermediate the Client's payment relationship with the LLM Providers. Inference invoices flow directly from each Provider to the Client on the Client's own provider account.
4.3. No payment services under PSD2. The Company does not constitute a payment services provider within the meaning of Directive (EU) 2015/2366 (PSD2) or Article L314-1 of the French Code monétaire et financier. The Company receives subscription fees from the Client for its own services, processed by Stripe, Inc. (a licensed payment institution); it does not receive, hold, or transfer funds on behalf of the Client or of the LLM Providers.
4.4. No electronic money. The Company does not issue electronic money within the meaning of Article L525-1 of the French Code monétaire et financier or Directive 2009/110/EC. No prepaid balance, credit pack, monetary value, voucher or equivalent payment instrument is issued by or held at the Company.
4.5. No prudential supervision. The Company does not operate as an electronic money institution, a payment institution, or a credit institution, and is not supervised as such by the Autorité de contrôle prudentiel et de résolution (ACPR) or any equivalent competent authority in the European Economic Area.
4.6. Technical intermediary. The Company acts as a technical intermediary only. It analyses routing metadata (request size, headers, detected tools and intent) and forwards the request to the Provider selected by the routing engine. The contractual relationship for inference is strictly between the Client and the LLM Providers, on the basis of credentials the Client maintains directly with each Provider.
4.7. Regulatory-evolution clause. Should the French or European regulatory framework evolve in a manner that would require the Company to obtain a specific authorisation, the Company undertakes to either (i) obtain the required authorisation within the prescribed timeframe, or (ii) migrate to a compliant billing model within a reasonable transition period, without loss of value for existing Clients.
5. Service Level
5.1. The Company targets 99.9% uptime for the routing proxy. This excludes planned maintenance (announced 48 hours in advance) and outages of third-party LLM providers, which are outside the Company's control.
5.2. The routing decision adds less than 5 milliseconds of latency (p99) to each request. The Company is not responsible for latency introduced by third-party LLM providers.
5.3. The burn-rate alerting and anti-abuse systems may throttle or flag requests identified as anomalous (duplicate requests, cost spikes, zombie agents, enumeration patterns). Clients can configure thresholds via the dashboard.
5.4. In the event of a verified Service unavailability (routing proxy down) exceeding 24 consecutive hours, the Client is entitled to a pro-rata credit on the next invoice, calculated on the basis of the downtime duration relative to the current billing cycle. Clients holding an annual subscription may elect a refund to the original payment method instead, issued within 15 business days of the Client's written request.
6. Acceptable Use
6.1. The Service must not be used for illegal activities, generation of harmful or illegal content, or any purpose that violates the acceptable use policies of the underlying LLM providers.
6.2. The Company does not monitor, store, or inspect the content of prompts or responses (see Privacy Policy). However, the Company reserves the right to act on abuse reports it receives from downstream LLM providers, law enforcement, or other credible sources.
6.3. Automated systems that generate excessive routing volume without user interaction may be throttled by the anti-abuse and burn-rate alerting systems. The Company may, in addition, temporarily block IP addresses exhibiting credential-stuffing or enumeration patterns against HiWay API keys.
6.4. Anti-fraud and anti-abuse clauses. The following behaviours constitute a material breach of these Terms and authorise the Company to suspend or terminate the Client's account immediately, without prior notice and without refund of the current billing cycle:
- (a) creating multiple accounts to repeatedly claim the Free tier quota or circumvent plan limits;
- (b) using stolen, fraudulent, or otherwise unauthorised payment methods;
- (c) initiating chargebacks without first following the dispute resolution pathway described in Section 7;
- (d) circumventing burn-rate alerting, Budget Controls, per-key rate limits, new-country 2FA challenges, or any other safety mechanism, whether documented or not;
- (e) reverse-engineering, scraping, probing, or otherwise attempting to extract the Company's routing logic or infrastructure beyond the documented API surface;
- (f) sharing, reselling, or sublicensing Service access or HiWay API keys to third parties outside the Client's organisation without the Company's written consent;
- (g) using the Service to train, fine-tune, or benchmark competing routing products;
- (h) any activity reported by a downstream LLM provider as violating the provider's own terms of service.
7. Chargebacks and Disputes
7.1. Dispute resolution pathway. Before initiating a chargeback with a payment card issuer, the Client undertakes to contact the Company's billing support at billing@hiway2llm.com with a clear description of the disputed charge and the relevant Stripe invoice identifier. The Company will acknowledge the dispute within 2 business days and provide a substantive response within 5 business days.
7.2. Where a dispute is resolved in the Client's favour, the Company will issue a refund to the original payment method within 10 business days.
7.3. Chargebacks without prior dispute. A chargeback initiated without the Client first attempting the dispute resolution pathway described in Section 7.1 is considered a breach of good faith. In such cases, the Company reserves the right to:
- (a) suspend the Client's account until the chargeback is resolved with the payment card issuer;
- (b) invoice the Client for the amount of the chargeback plus associated processing fees (typically €15–€25 per chargeback);
- (c) refuse future transactions from the Client;
- (d) report the chargeback to chargeback-alert networks (Ethoca, Verifi) where legally permitted;
- (e) pursue recovery of the disputed amount and associated fees through legal counsel.
7.4. Friendly fraud. Chargebacks identified as friendly fraud (legitimate purchases disputed as fraudulent) may be referred to legal counsel for recovery of the disputed amount plus all associated fees, including reasonable attorney fees.
8. Suspension and Termination
8.1. Suspension for cause. The Company may suspend a Client's access to the Service immediately, without prior notice, if the Company has reasonable grounds to believe that:
- the Client is in material breach of these Terms (including Section 6.4);
- the Client's account is the source of abuse reported by a downstream LLM provider;
- the Client is the subject of a credible fraud report or chargeback dispute;
- continued operation of the account poses a security, legal, or financial risk to the Company or to other Clients.
8.2. Termination by the Client. The Client may cancel their subscription at any time through the dashboard or by contacting support. Cancellation takes effect at the end of the current billing cycle; subscription fees already paid for the current cycle are non-refundable, unless the cancellation is triggered by a material breach of these Terms by the Company.
8.3. Termination by the Company. The Company may terminate a Client's account (i) with 30 days written notice for convenience, or (ii) immediately in the cases described in Section 8.1. In the event of termination for convenience by the Company, the unused pro-rata portion of any prepaid annual subscription is refunded to the original payment method within 30 days.
8.4. Effect of termination. Upon termination of an account, the Client's HiWay API keys are revoked, stored BYOK provider keys are deleted within 7 days, per-user usage counters are preserved for 24 months for audit and compliance purposes, and the Privacy Policy's zero-prompt-logging guarantee continues to apply.
9. Intellectual Property
9.1. The routing algorithms, scoring engine, Guardian system, transaction ledger, and dashboard are the exclusive intellectual property of Mytm-Group SAS.
9.2. Client data (prompts, responses) remains the exclusive property of the Client. The Company claims no rights over Client content and does not store it (see Privacy Policy).
9.3. Usage metadata (token counts, model selections, costs, latency) may be aggregated and anonymised for Service improvement and for public reporting in aggregate form only.
10. Limitation of Liability
10.1. The Company's total liability to any single Client is limited to the amount of subscription fees paid by that Client in the 12 months preceding the claim.
10.2. The Company is not liable for the output quality of third-party LLM providers, nor for routing decisions that result in lower-quality outputs from cheaper models, nor for provider pricing changes that affect the Client's effective consumption rate.
10.3. The Company is not liable for losses resulting from unauthorised use of Client API keys, compromised Client accounts, or Client misconfiguration of Budget Controls or Guardian rules.
10.4. Nothing in these Terms limits liability for gross negligence, wilful misconduct, or death or personal injury caused by negligence, to the extent such limitation is prohibited by applicable law.
11. Governing Law and Jurisdiction
11.1. These Terms are governed by French law. Any disputes arising out of or in connection with these Terms shall be submitted to the exclusive jurisdiction of the competent courts of Paris, France.
11.2. For consumers residing in the European Union, mandatory consumer protection laws of the consumer's country of residence apply in addition to these Terms where relevant.
