Terms of Service
Effective date: June 13, 2026
Welcome to Diego. By accessing or using our service you agree to be bound by these Terms of Service (“Terms”). Please read them carefully. If you do not agree, do not use the service.
1. The Service
Diego is an AI-powered voice conversation tutor for Spanish. We provide software-as-a-service (“SaaS”) accessible via our website and related applications (collectively, the “Service”).
2. Eligibility
You must be at least 13 years old to use the Service. If you are under 18, you represent that a parent or legal guardian has reviewed and agreed to these Terms. By creating an account you represent that all information you provide is accurate and that you have the authority to enter into these Terms.
3. Account Registration
You must create an account to access most features. You are responsible for maintaining the confidentiality of your credentials and for all activity under your account. Notify us immediately at [email protected] if you suspect unauthorised use. We may require an invitation code during sign-up; sharing or selling invitation codes is prohibited.
4. Subscription & Credits
The Service operates on a credit (minutes of practice) model. Credits are allocated on subscription plans or purchased as one-time packs. Monthly subscription credits reset with each billing period and do not roll over. One-time pack credits do not expire. All fees are stated and charged in U.S. dollars (USD) and are non-refundable except as required by applicable law or as expressly stated in a refund policy.
Plans described as “unlimited” are intended for normal personal learning use. We may apply reasonable usage limits to any account whose usage materially and consistently exceeds the typical usage of an average user on the same plan, or that reflects automated, shared, resold, or otherwise abusive use. Where practical we will contact you before applying such limits, except where we reasonably believe the activity is abusive or harmful to the Service or other users.
We use Stripe to process payments. By making a purchase, you also agree to Stripe's Terms of Service.
5. Acceptable Use
You agree not to:
- Use the Service for any unlawful purpose or in violation of any law.
- Attempt to reverse-engineer, decompile, or extract our AI models, prompts, or proprietary technology.
- Circumvent rate limits, cost caps, or any other technical restrictions.
- Share your account credentials or allow others to use your account.
- Generate, transmit, or store content that is harmful, offensive, or violates third-party rights.
- Scrape, crawl, or systematically download content from the Service.
- Use automated means to interact with the Service except via our official API, if any.
6. Intellectual Property
The Service, including all software, designs, audio models, and underlying AI systems, is owned by Diego or its licensors and is protected by intellectual property laws. These Terms do not grant you any ownership interest in the Service.
Conversation content you create during sessions is yours. By using the Service you grant us a limited, non-exclusive licence to process and store that content solely to provide and improve the Service.
7. Privacy
Your use of the Service is governed by our Privacy Policy, which is incorporated into these Terms by reference. Please review it carefully.
8. Third-Party Services
The Service integrates third-party providers including Anthropic (AI), Deepgram (speech recognition), Cartesia (text-to-speech), and Supabase (authentication and database). Your use of these components is also subject to their respective terms and privacy policies.
9. Disclaimers
THE SERVICE IS PROVIDED “AS IS” AND “AS AVAILABLE” WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT. WE DO NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED, ERROR-FREE, OR THAT RESULTS OBTAINED FROM USE OF THE SERVICE WILL BE ACCURATE OR RELIABLE.
Language learning outcomes depend on individual effort and practice. We make no guarantee of any particular level of language proficiency.
10. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, DIEGO AND ITS AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AND LICENSORS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, NOR FOR ANY LOSS OF PROFITS, DATA, GOODWILL, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR RELATING TO YOUR USE OF OR INABILITY TO USE THE SERVICE.
OUR TOTAL CUMULATIVE LIABILITY TO YOU SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID TO US IN THE TWELVE MONTHS IMMEDIATELY PRECEDING THE CLAIM, OR (B) US$50.
11. Indemnification
You agree to defend, indemnify, and hold harmless Diego and its affiliates from and against any claims, damages, obligations, losses, liabilities, costs, or debt arising from (a) your use of the Service, (b) your violation of these Terms, or (c) your violation of any third-party right.
12. Termination
We may suspend or terminate your account at any time for violation of these Terms or for any other reason at our discretion. Upon termination, your right to use the Service ceases immediately. Unused credits from one-time packs will be refunded on a pro-rata basis where required by applicable law. Monthly subscription credits are non-refundable on termination.
You may close your account at any time by contacting us at [email protected].
13. Changes to the Terms
We may update these Terms from time to time. When we do, we will post the revised Terms here with a new effective date and, where the changes are material, notify you by email or in-app notice. Continued use of the Service after changes take effect constitutes acceptance of the revised Terms.
14. Governing Law & Dispute Resolution
These Terms are governed by the laws of the State of Delaware, USA, without regard to its conflict of law principles. Any dispute arising out of or relating to these Terms or the Service shall be resolved by the state and federal courts located in Delaware, USA, except where applicable consumer protection law requires otherwise.
15. Severability & Waiver
If any provision of these Terms is found invalid or unenforceable, that provision will be limited to the minimum extent necessary and the remaining provisions will remain in full force. Our failure to enforce any provision is not a waiver of our right to enforce it in the future.
16. Entire Agreement
These Terms, together with the Privacy Policy and any other policies incorporated by reference, constitute the entire agreement between you andDiego with respect to the Service and supersede all prior agreements.
