1. Scope and acceptance
1.1 These Terms govern access to and use of the Rabel API and its documentation, sample files and sign-up pages (the “Service”).
1.2 Using the Service, or creating a key, constitutes acceptance of these Terms. A person who does not accept them must not use the Service.
1.3 The Service is offered to persons at least 18 years of age, or the age of majority where they reside, if higher.
1.4 Use of the Service is also governed by the Privacy Notice.
2. Beta status
2.1 The Service is in beta. It is offered as is and as available, is not covered by any service level, and is not intended for production use on which a person depends.
2.2 Features, interfaces, limits and prices may change, be suspended or be withdrawn at any time. Rabel will use reasonable efforts to give notice of material changes at the sign-up address.
2.3 Rabel may end the beta, restrict access to it, or end the Service. Credit that has been paid for is treated under Section 5.
3. Account and key
3.1 An account is created with an email address, which must be confirmed through a link sent to it.
3.2 One key is issued on confirmation and is displayed once. Rabel stores only a hash of the key and cannot display it again.
3.3 The user is responsible for the safekeeping of the key and for all use made with it. A lost or exposed key is to be reported to Rabel.
3.4 Accounts and keys are not transferable. Rabel may disable a key that is used in breach of these Terms.
4. Free use, limits and capacity
4.1 Use of the Service begins free of charge. The amount of free use, the limits per key and the price are set out in the documentation and may be changed at any time.
4.2 Use is measured in seconds for which a connection to the Service is open, from the Service’s ready message until the connection closes.
4.3 The Service has limited capacity. A request may be refused, including with a 429 response where a key is over its own limit and a 529 response where the Service is out of capacity. A refused request is not a breach by Rabel.
4.4 Rabel records each 529 response against the key’s email address and the time, in order to follow up on demand.
4.5 A request is refused with a 402 response where a key has neither free use nor credit remaining.
5. Credit and payment
5.1 Use beyond the free amount is paid for by credit bought in advance.
5.2 Credit is bought through Stripe, Inc., on Stripe’s hosted payment page. Rabel does not receive or store card details. Stripe’s terms apply to the payment.
5.3 Use draws credit down by the second, as measured under Section 4.2, at the price in the documentation at the time of use.
5.4 Credit has no cash value and is not transferable. Except where required by law, or where Rabel ends the Service other than for the user’s breach, bought credit is not refunded. If Rabel ends the Service other than for the user’s breach, unused bought credit is refunded on request.
5.5 Taxes, where due, are the user’s responsibility.
6. User text
6.1 Text sent to the Service (“User Text”) remains the user’s. The user grants Rabel a non-exclusive, worldwide licence to process User Text, itself and through the processors named in the Privacy Notice, for the sole purpose of producing the output returned to that user, for the duration of the request.
6.2 Rabel does not retain User Text. What Rabel keeps is set out in the Privacy Notice.
6.3 The user warrants that it has the right to send User Text and that sending it does not violate any law or the rights of a person whose words or information it contains. Where User Text contains the words of another person, the user is responsible for obtaining any consent required.
6.4 The user must not send User Text containing protected health information, payment card data or government identifiers.
7. Output
7.1 The Service returns speculative output: predictions, made from User Text, of what a speaker may say next. The Service also returns User Text with that output. Speculative output is a guess. It is not a transcript, a statement of what was said, or a statement of what a person intends.
7.2 Output is provided without warranty of accuracy, completeness or fitness for a purpose. The user is solely responsible for evaluating output and for any reliance on it.
7.3 As between the parties, the user owns the output returned to the user.
8. Acceptable use
The user must not:
(a) use the Service unlawfully, or to infringe, defraud, harass or impersonate;
(b) exceed or circumvent limits, or use more than one key to avoid a limit;
(c) probe, scan or test the Service’s security without Rabel’s written consent;
(d) copy, extract or reverse engineer the Service or its models, or use output to train a competing model;
(e) resell or sublicense access to the Service;
(f) send User Text containing the words of persons under 18 without the consent of a parent or guardian;
(g) interfere with the Service or with other users’ use of it.
9. Ownership
9.1 Rabel owns the Service, the documentation and all related rights. No right is granted except the right to use the Service in accordance with these Terms.
9.2 Feedback may be used by Rabel without restriction or payment.
10. Disclaimer
10.1 The Service and its output are provided as is and as available. To the extent permitted by law, Rabel disclaims all warranties, express or implied, including merchantability, fitness for a particular purpose, non-infringement, accuracy, availability and uninterrupted or error-free operation.
11. Limitation of liability
11.1 To the extent permitted by law, Rabel is not liable for indirect, incidental, special, consequential or punitive damages, or for loss of profits, revenue or data.
11.2 To the extent permitted by law, Rabel’s total liability arising from the Service is limited to the greater of the amount the user paid to Rabel in the twelve months before the event giving rise to the claim and US$100.
12. Indemnity
12.1 The user indemnifies Rabel against claims, losses and costs arising from the user’s User Text, the user’s use of output, or the user’s breach of these Terms.
13. Suspension and termination
13.1 The user may stop using the Service at any time and may request closure of the account.
13.2 Rabel may suspend or end access at any time, with or without notice, including for breach of these Terms.
13.3 Sections 6.3, 7, 9, 10, 11, 12, 14 and 15 survive termination.
14. Governing law
14.1 These Terms are governed by the law of the State of Delaware, without regard to conflict-of-law rules.
14.2 The state and federal courts located in Delaware have exclusive jurisdiction over disputes arising from these Terms, subject to Section 15.
15. General
15.1 Changes to these Terms are made by posting a revised version with a new effective date; continued use after the effective date is acceptance. Material changes are also sent to the sign-up address.
15.2 These Terms and the Privacy Notice are the entire agreement between the parties on the Service.
15.3 A provision held unenforceable is limited to the minimum extent necessary and the remainder continues in force.
15.4 Rabel may assign these Terms. The user may not without Rabel’s written consent.
15.5 Notices to Rabel are sent to the contact above. Notices to the user are sent to the account’s email address.
