Terms of Service

1. Provider & scope

GradeLogic™ is operated by a German Unternehmergesellschaft (haftungsbeschränkt). The full provider details — legal name, registered address, commercial register and court, managing director and VAT identification number — are set out in our Impressum.

These Terms apply where you use GradeLogic™ as a consumer (§13 BGB) — an individual acting outside any trade, business or profession. Use by schools, universities and other institutions is governed by a separate agreement together with our Data Processing Agreement.

2. The service

GradeLogic™ is an AI-assisted exam grading and analysis tool. It is local-first: your exam files, roster, student identities and accepted results are held in your browser's storage, and content is sent for cloud processing only when you authorise a specific operation.

AI output is assistive. GradeLogic™ proposes grades; you decide them. Nothing in the service transfers the assessment decision away from you. You are responsible for reviewing AI output before relying on or exporting it, and the service does not send grades to students. This allocation of roles is a feature of the service, not a limitation of our liability — see §11.

3. Accounts & eligibility

Accounts use Google sign-in and are personal to one instructor. For new users, an account is provisioned only after subscription checkout is completed and payment is verified; Google sign-in by itself does not create free service access. You must be at least 18 years old. You are responsible for activity under your account and for keeping access to it secure.

4. Subscription, Grading Credits & prices

What you are buying. A GradeLogic™ subscription gives you access to the service for the billing month, including a monthly capacity of Grading Credits. While your paid subscription is active, you may also buy a one-time pack of 500 additional Grading Credits through the billing page. Credit packs are optional and are not subscriptions.

How the allowance works. Your allowance is granted at the start of each billing month and resets at the start of the next one. Unused credits do not carry over. On the current monthly subscription, the allowance and billing period renew together each month unless the subscription is cancelled. Purchased credit-pack credits expire 30 days after payment and do not renew automatically. Credits are consumed from the lot with the earliest expiry date first.

Prices. All prices shown are total prices including value added tax. The price of a subscription or credit pack, the included number and validity of credits, and how many credits each AI operation consumes are stated before you order, and the service shows an estimate before an operation is run.

Payment. Payment is processed by Stripe. We do not receive or store your full card details. You will receive an order confirmation containing these Terms and the withdrawal information on a durable medium.

Cancellation and refunds. Ending the subscription revokes unused monthly subscription credits, but does not revoke purchased credit-pack credits before their stated expiry date. If Stripe confirms a refund for a credit pack, any unused credits from that pack are revoked. A refund involving credits that have already been used may require support review.

5. Right of withdrawal (Widerrufsrecht)

As a consumer you have a statutory right to withdraw from the contract within fourteen days without giving any reason. The period begins when the contract is concluded.

Because the service is available immediately, we ask you at checkout to expressly request that we begin performance before the withdrawal period ends, and to confirm that you acknowledge losing your right of withdrawal once we have fully performed. We will not begin before you give both confirmations, and we will record them.

To withdraw, an unambiguous statement to the contact address in §15 is sufficient. A model withdrawal form is provided with your order confirmation.

6. Term & cancellation

The subscription runs for the billing period you chose and renews automatically unless cancelled. You may cancel at any time with effect from the end of the current period. Access and your remaining allowance continue until then; the allowance is not extended beyond it.

You can cancel using the cancellation button available on every page of our website. It does not require you to sign in: it asks only for your contract number and the email address on the contract, and we confirm the cancellation to that address in text form straight away. While signed in you can also cancel in the billing portal our payment provider hosts, reachable from your billing page, and you may cancel by any other clear statement to the contact address in §15.

7. Acceptable use

Do not upload content you have no right to process, attempt to disrupt or circumvent limits on the service, or use it to break the law or infringe anyone's rights.

You must have a lawful basis for processing the student data you bring to GradeLogic™. Consent is usually not the right basis in an educational setting: the relationship between an instructor and a student rarely allows consent to be freely given. Ordinarily you or your institution act as controller on a basis such as the performance of a public task or a legitimate interest, and we act on your instructions as processor. Our Data Processing Agreement and FERPA Support Overview describe that arrangement.

8. Your responsibilities & student data

You decide what leaves your browser. Before any cloud processing you review a local preview of the redacted or excluded regions and authorise the transfer. You are responsible for carrying out that review, for verifying AI-generated grades before releasing them, and for complying with your institution's policies and applicable education-privacy law.

See our Privacy Policy for what we process and why.

9. Intellectual property

GradeLogic™ and its software are ours. Your exam content and results remain yours. You grant us a limited licence to process the content you submit, solely to provide the service you asked for. We do not use your assessment content to train AI models.

10. Conformity of the digital service & updates

We owe you a service that conforms to this contract and to what you can objectively expect of a service of this kind (§§327 ff. BGB). Where it does not, you have the statutory remedies: subsequent performance, and if that fails, a price reduction or termination, plus damages where the conditions are met. We do not exclude or limit these rights.

For as long as you hold a subscription we will provide the updates — including security updates — needed to maintain conformity, and we will inform you about them. If you do not install an update we make available, that does not affect our liability for a lack of conformity that the update would have prevented, provided we told you about the update and the consequences of not installing it.

AI-assisted grading is inherently probabilistic and may produce incorrect suggestions. That characteristic is described here and in our Responsible AI Policy so that it forms part of what you agree the service is — it does not displace the conformity rights above.

11. Liability

We are liable without limitation:

• for damage caused intentionally or by gross negligence;
• for injury to life, body or health;
• under a guarantee we have expressly given;
• where liability is mandatory under the Produkthaftungsgesetz.

For ordinary negligence we are liable only where we breach a material contractual obligation — one whose fulfilment is essential to the purpose of this contract, or on which you were entitled to rely — and then only for the foreseeable damage typical of this kind of contract. Liability is otherwise excluded.

These limits also apply to our legal representatives and to people we engage to perform the contract. Nothing here alters the statutory burden of proof.

Grading remains your decision (§2). Where you rely on or distribute a grade without reviewing it, the loss does not arise from a breach of our obligations — but we do not exclude liability for a defect in the service that caused it.

12. Changes to these Terms

We may change these Terms only where there is a valid reason: a change in the law or in case law, a decision by a court or authority, a change in the service or in how it is technically provided, or a security requirement. We will not use this to alter the essential terms of the contract — the service you receive, the price, or the term.

We will notify you of any change at least six weeks before it is intended to take effect, by email or in the application, setting out what is changing and why. If you object before that date, the change does not apply to you; either of us may then terminate the contract with effect from the end of the current billing period. If you do not object, the change takes effect on the stated date — we will tell you that in the notice.

13. Governing law, jurisdiction & language

German law applies, excluding the UN Convention on Contracts for the International Sale of Goods. If you live in another EEA state, this choice does not deprive you of the protection of the mandatory consumer-protection rules of your country of residence.

We do not impose a place of jurisdiction on you. The statutory rules apply: you may bring proceedings at the court for your place of residence, and we may sue you only there.

These Terms are published in German and English. The German version governs; the English version is provided for convenience.

14. Dispute resolution

We are not obliged to take part in consumer dispute resolution proceedings and do not currently do so. You remain free to bring your claim before the courts, and this does not affect any statutory right you have.
