Terms of Service (AGB)

1. Scope

These terms govern all contracts between M. Amin Sayegh, trading as PrinVox (a product of AIProCraft), Paul-Bertz-Str. 38, 09120 Chemnitz, Germany, e-mail: hello@prinvox.com (“Provider”) and businesses within the meaning of § 14 German Civil Code (“Customer”) for the use of the PrinVox software platform and its Margin Guard product. Contracts with consumers are excluded.

2. Service

Margin Guard calculates gross margin (revenue minus AI cost) per customer and plan, and AI cost per feature — from the Stripe revenue the Customer shares through Stripe Connect and from usage events the Customer’s backend sends to the Provider. The Provider does not call AI providers on the Customer’s behalf and does not receive the Customer’s API keys for them.

AI cost is calculated from the token counts the Customer sends and stored list prices for the exact model name given; discounts (for example for cached input or batch processing) are not modelled, so the cost is an upper bound. For a model without a stored price the cost stays unknown and the result is marked incomplete. Calculation is in US dollars only; there is no currency conversion.

For the connection the Provider requests Stripe’s standard Connect permission (scope read_write; Stripe offers a read-only scope only to Stripe Apps). The Provider’s software uses it only for read requests and never initiates payments, payouts, transfers or refunds.

Results are calculations from the Customer’s data. An event that was sent but whose model price is unknown is marked incomplete; an event that was never sent cannot be detected by the Provider and is missing from the results. Missing, late or wrong data leads to deviating or incomplete results. Results are not accounting, tax or legal advice. No particular business outcome is promised.

3. Conclusion, free evaluation, term, termination

The Customer signs in with a one-time code by e-mail or with Google and creates an account. A paid contract for a plan is concluded by completing the Checkout hosted by Stripe and the subsequent activation of the plan.

Plans are monthly subscriptions that renew monthly. The Customer can cancel at any time through Stripe’s customer portal (reachable from the “Billing” page). The “Billing” page shows whether and on which date the subscription ends.

For new accounts, for as long as the Provider offers it, a free evaluation is available: 14 days from the moment the Customer starts it, no payment method, once per account; the Basic plan’s features (up to 25 tracked customers, 30 days of reporting); at most 5,000 usage events in total and 60 per minute. The evaluation ends by itself without any charge and without automatic conversion into a subscription. After that new usage events are no longer accepted; stored data is kept.

4. Prices and payment

The prices in US dollars per month shown on the pricing page and in the Checkout at the time of purchase apply. Billing is monthly through Stripe; the Customer enters payment details only with Stripe. In accordance with § 19 UStG no VAT is shown separately.

5. Customer obligations

The Customer may only connect Stripe accounts it is authorised for. The ingestion key must be kept secret and used server-side only. The Customer is responsible for being entitled to transmit the identifiers it sends (for example customer identifiers); pseudonymous identifiers are recommended. Automated or abusive use beyond the booked scope is prohibited.

6. Availability

The Provider strives for high availability but does not owe a specific availability. Results depend on the reachability of Stripe and on the Customer’s delivery of events. Events that are not delivered (including after a free evaluation ends) cannot be detected by the Provider; they are simply missing from the results without any indication.

7. Liability

The Provider is liable without limitation for intent and gross negligence and for injury to life, body or health. For slight negligence the Provider is liable only for breach of essential contractual duties, limited to the typical, foreseeable damage and capped at the fees paid in the preceding 12 months. Liability under the German Product Liability Act remains unaffected.

Decisions the Customer takes on the basis of the results are the Customer’s responsibility.

8. Data, retention and deletion

Processing of personal data is governed by the Privacy Policy. No automatic deletion is implemented at present; the Provider deletes data on the Customer’s request. The history window named in a plan only determines the reporting period that can be displayed and is not a promise to delete at that point. Data export is not promised.

9. Changes to these terms

The Provider may announce changes to these terms by e-mail with four weeks’ notice. If the Customer does not object before they take effect, the amended terms are deemed accepted; the announcement will point this out. Earlier versions are kept.

10. Final provisions

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. Place of jurisdiction, where permissible, is Chemnitz. Should individual provisions be invalid, the remainder of the contract remains in force.
