1. Agreement. These Terms govern your access to and use of TertulIA (the "Site") and its courses and memberships (the "Service"). By creating an account, subscribing, or using the Service, you agree to these Terms. If you don't agree, please don't use the Service.
2. Who we are. The Service is operated by Dr. Diego Bonilla (sole proprietor), operating as TertulIA ("TertulIA," "we," "us"). Questions:
[email protected].
3. Your account. You must provide accurate information and keep your login secure. Accounts are for one individual and may not be shared. You're responsible for activity under your account. You must be the age of majority in your place of residence (or have a guardian's consent) to purchase.
4. Memberships and billing. TertulIA memberships are recurring subscriptions billed monthly or annually through our payment processor until cancelled. By subscribing you authorize us (via the processor) to charge your payment method each billing period at the then-current price. You can cancel anytime from your account; cancellation stops future charges and your access continues until the end of the current paid period (see section 14 below). We may change prices with reasonable notice; changes apply to the next billing period.
5. License to use the content. While your subscription is active, we grant you a personal, non-exclusive, non-transferable license to access the courses and to download the worksheets and notebooks for your own learning. This license ends if your subscription ends, except that worksheets and notebooks you've already downloaded remain yours to use personally.
6. Intellectual property and copyright. All content on TertulIA - including course videos, audio, worksheets, Colab notebooks, code, written lessons, graphics, and the TertulIA name and logo - is the intellectual property of Dr. Diego Bonilla / TertulIA, protected by copyright and other laws. Your access grants the personal license in section 5 only. You may not copy, republish, redistribute, sell, sublicense, publicly share, or post the videos or written materials; share your login; or use any TertulIA materials to train, fine-tune, or evaluate machine-learning systems - without prior written permission. Brief quotation for review or commentary, with attribution, is welcome.
7. Acceptable use. Don't: share or resell access; scrape, bulk-download, or systematically copy the Service; reverse-engineer the Site; remove notices; use the materials to train or evaluate machine-learning systems; or use the Service unlawfully.
8. Educational content and disclaimers. TertulIA is educational. AI tools change quickly; lessons reflect our understanding at the time of recording and may become outdated. THE SERVICE AND ITS CONTENT ARE PROVIDED "AS IS" AND "AS AVAILABLE," WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NON-INFRINGEMENT. Nothing here is professional, legal, financial, or investment advice. You're responsible for how you apply what you learn and for complying with the terms of any third-party AI tools you use.
9. Limitation of liability. To the maximum extent permitted by law, TertulIA and Dr. Diego Bonilla won't be liable for indirect, incidental, or consequential damages, or for amounts exceeding what you paid us in the 12 months before the claim. Some jurisdictions don't allow these limits, so they may not fully apply to you.
10. Termination. You may stop using the Service anytime. We may suspend or terminate access for breach of these Terms (for example, sharing logins or redistributing content).
11. Changes. We may update these Terms; we'll post the new date and, for material changes, give notice. Continued use means acceptance.
12. Governing law and disputes. These Terms are governed by the laws of the State of California, United States, without regard to conflict-of-laws rules. Any dispute arising out of these Terms or the Service will be brought in the state or federal courts located in Sacramento County, California, and you and we consent to that venue - except that either of us may bring an individual claim in small-claims court, and mandatory consumer-protection rights and forums in your country of residence still apply.

14. Refunds.
Subscriptions. TertulIA memberships are recurring subscriptions. You can cancel anytime from your account - your access continues until the end of the current paid period, and you won't be charged again.
No refunds. Because you control cancellation and keep access through the period you've already paid for, subscription charges - including monthly renewals and annual plans - are non-refundable, and we don't pro-rate or refund partial periods. We recommend cancelling before your next renewal date if you don't wish to continue.
Charged by mistake? If you believe you were charged in error (for example, a charge right after you cancelled), email us and we'll review it in good faith.
Free or sponsored access. Coupon-based or manually-granted free access involves no charge, so refunds don't apply.
How to request or ask questions. Email
[email protected] from your account address with your order number.
Your statutory rights (for example, EU/UK withdrawal rights for digital content, or consumer-protection rules in your country) are unaffected by this policy - see section 15.
15. Immediate access, and EU/UK withdrawal rights. Where you have a statutory right to withdraw from a distance contract for digital content (for example, the 14-day right under EU consumer law or the UK Consumer Contracts Regulations 2013), the following applies. By subscribing and gaining immediate access to the courses, you expressly request that we begin supplying the Service immediately, and you acknowledge that once supply has begun you lose your right of withdrawal for that billing period. If you would prefer to keep that right, do not access the course content and contact us within 14 days of subscribing.
16. General. Severability - if any provision is found unenforceable, the remainder stays in force. Entire agreement - these Terms, together with the Privacy Policy, are the whole agreement between you and us about the Service and replace any earlier understandings. No waiver - if we don't enforce a right, we haven't waived it. Assignment - you may not transfer your account or these Terms; we may assign them to a successor of the business. Force majeure - we're not liable for delays or failures caused by events beyond our reasonable control, including outages of the platforms and payment processors we rely on.
