Terms of Service

Last Updated: August 12, 2026

1. Acceptance of Terms

By downloading, installing, or using Merak ("the App" or "the Service"), you agree to be bound by these Terms of Service ("Terms"). If you do not agree, you must not use the App.

These Terms supplement, and do not replace, the Apple Licensed Application End User License Agreement ("Apple EULA"). In the event of a conflict between these Terms and the Apple EULA, the Apple EULA shall prevail to the extent of the conflict.

2. Description of Service

Merak is a structured learning app that helps users turn topics into paths, practice with real questions, and track progress through short learning sessions. The App provides:

• A curated library of learning paths across diverse topics
• The ability to create custom courses using AI-powered content generation. Merak Pro includes four custom courses per subscription period; every tier earns one custom course by completing a course, at most one per account per UTC calendar month. Learning points are a record of progress and are never spent. Generation remains subject to reasonable abuse prevention, safety review, and temporary service-capacity controls
• Quiz-based learning with multiple question formats
• Progress tracking, completion history, points, and milestone features
• Personal progress systems that help users continue paths without requiring endless sessions

3. License Grant and Restrictions

3.1 License

Subject to these Terms, we grant you a limited, non-exclusive, non-transferable, revocable license to use the App on any Apple-branded device you own or control, as permitted by the Apple App Store Terms of Service and the Usage Rules set forth therein.

3.2 Restrictions

You may NOT:

• Copy, modify, reverse engineer, decompile, or disassemble the App or any part thereof
• Rent, lease, lend, sell, redistribute, or sublicense the App
• Use the App for any illegal or unauthorized purpose
• Attempt to gain unauthorized access to our systems or other users' data
• Use automated tools, bots, or scripts to access the Service
• Share your account credentials with others
• Circumvent any security or access control measures

4. User Accounts

4.1 Account Creation

• You may use Merak as a guest, or create a full account with Sign in with Apple or Google Sign-In
• You must provide accurate information when creating an account
• You are responsible for maintaining the security of your account

4.2 Age Requirements

• You must be at least 13 years old to use Merak.
• If you are under 18, you may use Merak only with the permission of a parent or guardian, and that parent or guardian accepts these Terms on your behalf. Where the law of your country requires a parent or guardian to consent before a person of your age may use a service like Merak, that consent is required.
• Merak asks you to confirm that you meet the age requirement. Merak does not collect a date of birth for this check.
• During the current controlled pilot, access is further restricted to people who confirm they are at least 18 years old. This restriction applies to the pilot only and will be removed at public release.

4.3 Account Termination

• You may delete your account at any time through Settings → Account → Delete Account when signed in, or request deletion through support
• We reserve the right to suspend or terminate accounts that violate these Terms
• Upon deletion, your data is permanently removed in accordance with our Privacy Policy

5. Learning Models and Content Quality

5.1 How a path is built

A Merak path is not a single prompt to a chatbot. Each one is produced by a multi-stage generation pipeline in which every stage can reject the work of the one before it:

• Evidence first. Before any lesson text is written, Merak retrieves source material for the specific topic and fixes it as the evidence set for that build. Sourcing is weighted toward primary, academic, governmental, standards-body and professional references; social networks, forums and search-optimised aggregators are excluded in the request itself rather than filtered out afterwards.
• Claims are objects, not prose. The factual content of a path is planned as a ledger of individual claims before anything is written. Cards and questions are then rendered against those claims, so a fact cannot quietly change meaning between where it is taught and where it is tested.
• Grounding is checked, not assumed. Claims that are supposed to rest on retrieved evidence are re-checked against that evidence set. Claims that fail are repaired, re-sourced, or dropped before publication.
• A jury, not a single model. Finished material is reviewed by two independent model families, neither of which wrote it, so no model both authors and approves its own work.
• Failures are surgical. When a check fails, Merak regenerates the specific card, question or claim that failed — not the whole course — and re-runs the checks against the replacement.
• Shape is verified before publication. Content is validated against the real constraints of the app's screens, so a path cannot ship in a form the app cannot present honestly.
• Runs are bounded and reproducible. Every build runs inside fixed time, call and cost limits and fails closed rather than degrading quietly. Runs are seeded and recorded, so a given build can be inspected after the fact.

None of this makes generated content infallible, and Merak does not claim that it does. It is designed to make failure visible and bounded rather than silent. Material that survives every stage can still be wrong.

5.2 Limits

• Content may be created, reviewed, repaired, restricted, or rejected before broader availability
• Human review is targeted. Higher-risk topics, release candidates, and new content formats may receive human review before broader availability.
• Quality is earned, not assumed. Content that fails review may be repaired, restricted, or rejected.
• Merak is an educational platform designed to build understanding and spark curiosity. Like all educational tools, it is not a substitute for licensed professional advice in areas such as health, finance, law, or mental health
• Health, medical and mental-health topics. Merak does not diagnose conditions, recommend or adjust treatment, or give medical advice, and its content is not written or reviewed by a clinician. If a path touches your health, or the health of someone you care for, speak to a qualified healthcare professional before acting on anything you read here, and do not delay or discontinue care because of something a path said. In an emergency, contact your local emergency service — not an app.
• Money and law. The same applies to financial, legal and tax topics: Merak explains ideas, it does not advise on your situation. Speak to a licensed professional before making a decision that affects you.
• We are committed to content accuracy, but no educational resource is infallible. If you encounter an issue, report it through Merak Support.

6. User-Generated Content

6.1 Content You Create

When you create a learning path, you grant us a worldwide, non-exclusive, royalty-free, sublicensable, and transferable license to use, reproduce, distribute, display, and perform your path content in connection with the Service. This enables other users to take paths you create.

6.2 Content Standards

You agree that any path you create will not contain content that is:

• Illegal, harmful, threatening, abusive, or harassing
• Defamatory, obscene, or invasive of another's privacy
• Infringing on intellectual property rights of any party
• Deliberately false, misleading, or designed to cause harm

We reserve the right to remove any user-generated content at our sole discretion.

6.3 Feedback

Any feedback, suggestions, or ideas you provide about the Service may be used by us without any obligation to you.

7. Intellectual Property

7.1 Our Property

Merak, its logo, learning models, and all app content (including generated questions, cards, curriculum structures, and design elements) are the property of Merak and are protected by intellectual property laws. All rights not expressly granted are reserved.

7.2 Your Data

You retain ownership of your personal data. See our Privacy Policy for details on how we handle it.

8. Privacy

Your use of the App is also governed by our Privacy Policy, which describes what data we collect, how we use it, and your rights regarding your data. By using the App, you consent to the practices described therein.

9. Payment Terms

Some Merak features are free. Merak may also offer paid subscriptions, including Merak Pro, through Apple App Store in-app purchase.

Merak Pro includes four custom courses in each subscription period. The allowance resets when the subscription renews and does not carry over between periods. Generation may be queued or temporarily delayed to protect service reliability, content quality, safety, and fair use. Courses already started remain finishable after a subscription ends.

Current controlled-pilot exception: payments and subscriptions are disabled. Merak Pro is not for sale in this release. Any Pro capability shown to invited testers is a no-charge preview and does not create a subscription. Future paid availability requires a separate release decision and the in-app App Store terms shown at that time.

Subscription prices, billing periods, renewals, cancellations, and refunds are handled by Apple and are subject to Apple's payment terms and App Store policies.

10. Disclaimers
