Terms of Service

By creating an account or using Read Master, you agree to these Terms of Service and to our Privacy Policy. If you do not agree, you must not use the service.

You must be at least 13 years old (16 in the European Union) to create an account. You are responsible for maintaining the confidentiality of your credentials and for all activity that occurs under your account. Notify us immediately at [email protected] (opens your email app) if you suspect unauthorized access.

We grant you a personal, non-exclusive, non-transferable, revocable license to access and use Read Master for your own reading and study. This license does not include the right to resell, sublicense, or share access to the service, or to use the service to build a competing product.

By uploading or importing content into Read Master, you represent and warrant that:

• You are the copyright owner of the content, or you have obtained all rights, licenses, consents, and permissions necessary to upload it and to authorize Read Master to process it as described in these Terms and our Privacy Policy.
• Your use of the content within Read Master is lawful under applicable copyright law, including any fair use, fair dealing, or personal-use exception you rely upon.
• The content does not infringe the intellectual property rights, privacy rights, or any other rights of any third party.
• You will not upload content that circumvents or is designed to circumvent technological protection measures (TPMs) or digital rights management (DRM) controls applied by a rights holder.

Each time you upload a file, paste text, or import from a web address, we ask you to confirm: “I have the right to use this content, and I am importing it for my own personal learning.” That confirmation is part of these Terms, and we record when you gave it.

If that confirmation is false for something you import, you have broken these Terms. We may remove the content and suspend or close your account, as described in “Suspension and removal rights” below.

You may not use Read Master to:

• Upload infringing content. Upload, import, or process any book, document, or other material whose copyright you do not own and for which you have no lawful right to reproduce or process.
• Circumvent DRM. Upload or process content from which digital rights management (DRM) or other access controls have been stripped or circumvented, or use the service as a tool to facilitate DRM circumvention.
• Import from prohibited sources. Scrape, crawl, or mass-import content from websites, services, or platforms that prohibit such access in their terms of service or via robots.txt, or that require a separate license not held by you. See “Permitted sources” below for specific guidance on common sources.
• Share library access. Share your account credentials or library contents with other people to give them access to content they are not individually licensed to use, or otherwise use the service to run a lending or distribution operation for copyrighted works.
• Use AI outputs as substitutes for protected works. Systematically use AI-generated guides, assessments, or summaries as functional replacements for access to or purchase of the protected works from which they were derived, in a manner that substitutes for the market for the original work.
• Abuse the AI system. Use the AI features to generate content that is harmful, illegal, harassing, defamatory, or that violates the rights of others.
• Reverse-engineer or scrape the service. Scrape, mirror, decompile, reverse-engineer, or attempt to extract the source code of Read Master, or to access the service by automated means beyond what is expressly permitted.

This section provides guidance on specific common sources. This is not an exhaustive list — the general rules in “Prohibited uses” apply to all sources.

Project Gutenberg

• You may import works that are genuinely in the public domain in your jurisdiction and are available on Project Gutenberg. It is your responsibility to verify that a specific work is public domain in your jurisdiction before importing it.
• Works from Project Gutenberg may carry their own license or trademark terms (for example, the Project Gutenberg trademark and license terms that appear in certain editions). You agree to comply with those terms, including preserving any source, attribution, or license metadata that accompanies the work.
• Do not import Gutenberg works that are marked as restricted in your jurisdiction.

Public domain means the United States only. We treat a work as public domain only when Project Gutenberg's own record for that work says “Public domain in the USA.” We rely on that statement; we do not make our own legal review, and we make no claim about any other country. Some books on Project Gutenberg do not carry that statement, and anything you upload, paste or import from a web address is never treated as public domain, whatever the work is.

For a work that qualifies, we allow whole-book adaptation, and we share the material we generate from it (such as simplified text, picture descriptions and read-aloud audio) between readers. Those features rest on the work's United States status alone. We do not check where you are. If you are outside the United States, the same work may still be in copyright where you live, so check your local law before you import or use it.

Google Books

• You may use Read Master to view book metadata (title, author, description), search results, cover images, and public-domain book content available through the Google Books API or Google Books viewer, in accordance with Google's terms of service.
• You may follow links to the Google Books web reader or Google Play Books for copyrighted works you have purchased — Read Master surfaces these as outbound links only and does not reproduce the copyrighted content.
• You may not scrape, extract, or import the full text of copyrighted books from the Google Books preview or viewer, whether manually or via automation, unless you hold a separate license to that content from the copyright owner.

You retain all rights you hold in content you upload or import. By using Read Master, you grant us a limited, non-exclusive, royalty-free, worldwide license to:

• host and store the content on our infrastructure (Cloudflare R2, Neon);
• make copies as necessary for backup, replication, and disaster recovery;
• transform the content (for example, extract text, parse structure, normalize encoding) solely for the purpose of displaying it to you in the reader;
• transmit the content (or selected portions of it) to our authorized subprocessors — including Anthropic — solely to provide the AI features you request; and
• display the content to you through the Read Master interface.

This license is granted solely to enable us to provide the features you request. We do not share, redistribute, sell, or otherwise make your content available to any party beyond our authorized subprocessors, and only for the purposes described above.

This license terminates when you delete the content from your library or delete your account, subject to the retention periods described in our Privacy Policy.

Outputs generated by our AI tools (pre-reading guides, post-reading assessments, flashcards, explanations) are generated for your personal use. We do not claim ownership of these outputs.

AI outputs are best-effort and may contain inaccuracies, omissions, or errors — verify anything that matters to you with authoritative sources. AI outputs are not professional legal, medical, financial, or other expert advice.

Subscriptions renew automatically at the end of each billing period until you cancel. Payments are processed by Stripe — we never see or store your full card number. You may cancel at any time from Settings → Billing; cancellations take effect at the end of the current billing period. We do not issue refunds for partial billing periods except where required by applicable law or our refund policy published in the Help Center.

Guide packs and other credit packs are one-time purchases, separate from a subscription, and are valid for five years from the date of purchase. If a pack still has unused units when it expires, those units remain usable for a further 30-day grace period before being forfeited.

We will email you advance warnings before a pack expires, and your account shows a running countdown once a pack is approaching its expiry date.

This credit-pack expiry policy applies to packs purchased on or after the effective date of this section. Refunds for credit packs follow the general refund terms described in “Subscriptions and billing” above.

We aim to operate Read Master for as long as it is viable to do so, but we cannot guarantee that the service, or any individual feature, will remain available indefinitely. We reserve the right to modify, suspend, or discontinue the service (in whole or in part) at any time.

If we decide to discontinue paid access (Pro or Scholar) entirely, then except where prevented by law or by events beyond our reasonable control, we will:

• give registered users at least 90 days’ advance notice by email and through an in-app or on-site notice;
• provide a means to export your data (library metadata, notes, highlights, and AI outputs) before access ends, as described in our Privacy Policy; and
• for active subscribers, cancel any Pro or Scholar subscription as of the discontinuation date; no further charges will be taken, and the refund treatment for the affected billing period follows the general subscription terms in “Subscriptions and billing” above.

Nothing in this section limits any non-waivable rights you may have as a consumer under the laws of your country of residence.

In accordance with the Digital Millennium Copyright Act (DMCA) and as a condition of our eligibility for the DMCA safe-harbor provisions, Read Master closes the accounts of users who are repeat infringers of copyright.

The rule: we close an account that receives 3 valid, uncontested copyright takedown notices within any 12-month period. A notice counts once, however many items it names. A notice does not count if we find it invalid, or if you send a counter-notice and we accept it.

When your account reaches 2 counted notices, we email you a warning that one more may close it. No account is closed automatically: a member of our team reviews the record first. If we close your account, we email you to say so and to explain why.

When an account is closed under this policy:

• you can no longer sign in, and the account cannot be reactivated;
• any paid subscription is cancelled, and we give no refund for the unused part of the billing period, except where the law of your country requires one;
• your data is deleted on the same schedule as any other deleted account; and
• you may not open a new account.

This rule is a minimum. We may close an account sooner for flagrant or willful infringement. We apply this policy consistently and without discrimination. If you believe a notice was counted in error, write to [email protected] (opens your email app).

Read Master reserves the right to suspend access to, remove, or disable specific content or accounts in the following circumstances:

• We receive a valid DMCA takedown notice or other legally binding order from a rights-holder or competent authority requiring removal.
• We have reasonable grounds to believe that content violates these Terms, applicable law, or the rights of a third party.
• We have reasonable grounds to believe that a rights confirmation you gave when importing content was false.
• An account is used in a manner that poses a security risk to the service or other users.
• We are required to do so by applicable law or a binding court order.

Where feasible and not prohibited by law, we will provide advance notice and an opportunity to respond before taking action. Users whose content has been removed may submit a counter-notice as described in our DMCA Policy.

You can delete your account at any time from Settings → Privacy. Deletion triggers removal of your data from primary databases within the timelines described in our Privacy Policy.

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 uninterrupted or error-free operation, or that defects will be corrected.

To the maximum extent permitted by applicable law, Read Master LLC and its operators shall not be liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of or inability to use the service. Our total cumulative liability to you for all claims arising under or related to these Terms is capped at the greater of (a) the total fees you paid to Read Master in the twelve months immediately preceding the claim, or (b) USD $100.

These Terms are governed by the laws of [jurisdiction TBD — to be confirmed by counsel]. Any dispute that cannot be resolved informally will be submitted to the exclusive jurisdiction of the courts of [venue TBD — to be confirmed by counsel].

We may update these Terms from time to time. Material changes will be announced via email or in-app banner at least 30 days before they take effect. Continued use of Read Master after the effective date constitutes acceptance of the revised Terms.

General questions about these Terms go to [email protected] (opens your email app). For copyright or DMCA matters, see our DMCA Policy.
