Terms of Service

01Acceptance

These Terms of Service ("Terms") are a binding agreement between you and [LEGAL ENTITY NAME] ("RollMind", "we", "us"). By installing, accessing, or using the RollMind mobile application or the website at rollmind.app (together, the "Service"), you agree to be bound by these Terms and our Privacy Policy. If you do not agree, do not use the Service.

You must be at least 13 years old to use RollMind (16 in the EU/EEA and the UK, unless your country sets a lower age). If you are under 18, you confirm that a parent or guardian has reviewed and accepted these Terms on your behalf.

02The service

RollMind is a personal knowledge tool that reads public transcripts from YouTube videos you supply, uses an AI model to extract Brazilian Jiu-Jitsu techniques and relationships, and assembles them into a graph you can browse, edit, and use to generate game-plan trees and learning sequences. The Service includes an AI coach that answers questions grounded in your graph.

We may add, change, or remove features, sometimes without notice. We will not materially reduce the features in your paid plan during a billing period without offering you a prorated refund or equivalent credit.

03Your account

Sign-in is by one-time email code — there is no password. You are responsible for keeping access to your email account secure. You must not share your account, transfer it, or use someone else's. You must give us accurate information and keep it up to date.

One person, one account. Operating multiple accounts to bypass the free-tier video quota is a breach of these Terms.

04Subscriptions & billing

RollMind is free to use within the free-tier limits (currently 5 videos / month, the full seed graph, game plans from closed guard). The optional Pro plan is a paid auto-renewing subscription:

• Plans & price: Pro Monthly at US $14.99 / month, or Pro Annual at US $99 / year (≈ $8.25 / month, billed annually).
• Free trial: a 7-day free trial is offered on both plans. You will not be charged if you cancel before the trial ends.
• Billing: at the end of the free trial (or immediately if you skip it), you are charged at the start of each billing period to the payment method you provided.
• Renewal: renews automatically at the end of each period unless cancelled at least 24 hours before the renewal date.
• Where you pay: through the Apple App Store or Google Play if you subscribed in-app on a mobile platform that requires it, or through Stripe on the web.
• Switching plans: upgrades from monthly to annual apply remaining monthly credit pro-rated to the annual purchase. Downgrades from annual to monthly take effect at the next renewal.
• Taxes: prices exclude any sales tax, VAT, or GST that may apply, which will be added at checkout where required by law.
• Price changes: we will give you at least 30 days' notice by email and in-app before any price increase. The new price applies to your next renewal; if you do not accept it, cancel before that renewal.

05Cancellation & refunds

You can cancel any time:

• Stripe (web) subscriptions: Settings → Subscription → Manage in the app, which opens the Stripe billing portal.
• Apple App Store subscriptions: Settings → [your name] → Subscriptions on your device.
• Google Play subscriptions: Play Store → Profile → Payments & subscriptions → Subscriptions.

Cancellation takes effect at the end of the current billing period — you keep Pro access until then. We do not pro-rate partial months. Refunds for App Store and Play Store purchases are governed by Apple or Google respectively. For Stripe purchases, contact hi@rollmind.app within 14 days of a charge if you believe a refund is warranted; we consider requests in good faith.

EU/EEA and UK consumers have a statutory 14-day right of withdrawal from a digital subscription. By starting to use the Service immediately after subscribing, you ask us to begin performance during that period and acknowledge that you lose the right of withdrawal once the Service has been fully provided.

06Acceptable use

You agree not to:

• Reverse-engineer, decompile, or attempt to extract the source code of the Service, except where permitted by law.
• Probe, scan, or test the vulnerability of the Service except under a written authorization from us.
• Use the Service to process content you do not have the right to access.
• Use the Service to generate content that is unlawful, defamatory, harassing, or that infringes another person's rights.
• Resell, sublicense, or commercially exploit the Service or your access to it.
• Interfere with the operation of the Service, including by sending automated requests at a rate that degrades it for others.
• Use the Service to train competing AI models or to create a competing product.
• Bypass or attempt to bypass usage quotas, rate limits, or paywalls.

We may suspend or terminate your access if you breach these rules.

07Your content

You own the notes, tags, edits, custom edges, and chat messages you create in RollMind ("Your Content"). You grant us a worldwide, non-exclusive, royalty-free licence to host, store, transmit, and display Your Content solely to provide the Service to you. We do not use Your Content to train AI models.

You can export Your Content from inside the app (Markdown / Anki on Pro), or by emailing hi@rollmind.app for a JSON export.

08Third-party content

The YouTube videos you save and the transcripts we read are not our content. They belong to the original creators and are subject to YouTube's Terms of Service. RollMind reads only public transcripts that creators have made available, and the source video is always linked back from the technique it produced. We do not download, host, or redistribute video files.

If you are a rights holder and believe content has been used in a way that infringes your rights, contact hi@rollmind.app with the details listed in section 16.

09Training disclaimer

RollMind is a software tool for organizing and recalling techniques you encounter in instructional content. It is not a substitute for in-person instruction by a qualified coach, and the technique descriptions, decision trees, and coach responses it generates are summaries — they may be incomplete, miss critical safety details, or be inaccurate.

Do not attempt techniques you see in the app without proper training, supervision, and a consenting partner. You assume all risk associated with practicing or performing any technique referenced in or generated by the Service. Tap early, train smart, and listen to your coach.

10Warranties

The Service is provided "as is" and "as available". To the maximum extent permitted by law, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, non-infringement, and accuracy. We do not warrant that the Service will be uninterrupted, error-free, or that any data, technique extraction, or coach response will be accurate or complete.

Some jurisdictions do not allow the exclusion of certain warranties — to that extent, the disclaimers in this section do not apply to you, and the warranty period for any non-excludable warranties is the minimum permitted by your local law.

11Limitation of liability

To the maximum extent permitted by law, in no event will RollMind, its affiliates, officers, employees, or service providers be liable for any indirect, incidental, special, consequential, or punitive damages, or any loss of profits, revenue, data, use, or goodwill, arising out of or in connection with these Terms or your use of the Service.

Our total aggregate liability arising out of or in connection with these Terms or the Service is limited to the greater of (a) the amount you paid us for the Service in the 12 months preceding the event giving rise to the liability, or (b) US $50.

Nothing in these Terms excludes or limits liability that cannot be excluded or limited under applicable law, including liability for death or personal injury caused by negligence, fraud, or fraudulent misrepresentation.

12Indemnification

You agree to indemnify and hold harmless RollMind from any claims, damages, liabilities, costs, and expenses (including reasonable legal fees) arising out of or related to (a) your breach of these Terms, (b) Your Content, or (c) your misuse of the Service.

13Termination

You can stop using the Service and delete your account at any time (see Account Deletion). We may suspend or terminate your access if you breach these Terms, if your account becomes inactive for an extended period, or if we discontinue the Service. If we terminate the Service entirely, we will give reasonable advance notice and refund any pre-paid amounts for unused service.

Sections that by their nature should survive termination — including ownership, disclaimers, limitation of liability, indemnification, and governing law — survive.

14Changes to these terms

We may update these Terms from time to time. If the changes are material, we will notify you by email and in-app at least 30 days before they take effect. Your continued use of the Service after the effective date constitutes acceptance. If you do not accept, stop using the Service and delete your account before the effective date.

15Governing law

These Terms are governed by the laws of [GOVERNING JURISDICTION, e.g. the State of California, USA], without regard to its conflict-of-laws rules. Any dispute arising out of or relating to these Terms or the Service will be resolved in the courts of [VENUE], and you and we consent to the personal jurisdiction of those courts.

Nothing in this section deprives you of any mandatory consumer-protection rights under the law of your country of residence.
