Terms of Service
Effective Date: June 4, 2026
Last updated: July 13, 2026
These Terms of Service ("Terms") govern your access to and use of the AI Book Editor application (the "App") and related website services at aibookeditor.com (the "Website"), provided by Dmesis, Inc. ("Dmesis," "we," "us," or "our"). AI Book Editor is a product owned and operated by Dmesis, Inc. By downloading, installing, accessing, or using the App or Website, or by creating an account, you agree to these Terms. If you do not agree, do not use the App or Website.
Our Privacy Policy at aibookeditor.com/privacy-policy and our Cookie Policy at aibookeditor.com/cookie-policy are incorporated into these Terms by reference.
We may update these Terms from time to time. We will post updated Terms on the Website and, where feasible, notify you by email to your account address. Material changes will be effective no sooner than thirty (30) days after notice where required by law. If you do not agree to updated Terms, you must stop using the App and Website and cancel your subscription as described in Section 3 before the effective date where applicable.
1. Eligibility and Acceptance
You must be at least eighteen (18) years old and have legal capacity to enter a binding contract. By using the App, you represent and warrant that you meet these requirements, that your use complies with all applicable laws, and that you satisfy the eligibility, geographic, and restricted-party requirements in Section 4 (Export Controls, Sanctions & Geographic Restrictions).
1.1 Acceptance of updated Terms
We may publish revised versions of these Terms from time to time. Each version is identified by its effective or last-updated date (or another version identifier we display in the App or on the Website).
If you have previously accepted an earlier version, we may require you to review and affirmatively accept or reject the current version before you can continue to use the App — including when you next sign in after we publish an update. We may present the updated Terms in the App and ask you to scroll through them and choose "I Accept" or "I Do Not Accept" (or equivalent). Until you accept the current version, we may limit or suspend your access to the App.
If you reject updated Terms, you must not use the App. You may cancel your subscription through your account or billing settings. Rejecting updated Terms does not by itself cancel a paid subscription; you remain responsible for charges until you cancel as described in Section 3.
Your acceptance of a specific version of these Terms is binding for that version. Acceptance of an earlier version does not constitute acceptance of a later version. We may record which version you accepted and when, as described in our Privacy Policy.
On the Website, where we do not require separate affirmative acceptance in the App, continued access or use after the effective date of updated Terms may constitute acceptance where permitted by applicable law.
The App is intended for users in jurisdictions where its use is lawful and where the service is available. Access from comprehensively sanctioned jurisdictions, locations where we block or restrict the service, or by restricted parties is prohibited. See Section 4.
2. Account Registration and Security
You must register an account with a valid email address. You agree to provide accurate, current, and complete information and to keep it updated.
You are solely responsible for maintaining the confidentiality of your credentials and for all activity under your account. Notify us promptly at support@aibookeditor.com or through the signed-in Contact form on the Website if you suspect unauthorized access.
Accounts are personal and non-transferable. You may not share, sell, rent, or assign your account.
We may suspend or terminate your account if we reasonably believe you violated these Terms (including Section 4), engaged in fraud or abuse, or pose a security or legal risk.
Optional third-party sign-in (such as Google on the App or Website) is subject to that provider's terms. We are not responsible for third-party identity services.
3. Subscription, Billing, and Word Credits
3.1 Plans and credits
Subscription plans, features, and word credit allowances are described on the Website (aibookeditor.com/pricing). Word credits are consumed when you use metered AI features according to our metering rules.
Word counts used for billing and quotas are determined by our system and may differ slightly from an informal count due to formatting or other factors. Metering is provided "as is"; we do not issue refunds or credits solely for minor counting variance.
Word credits, subscription features, and AI usage are licensed only for use in permitted jurisdictions and by permitted users, as further described in Section 4.
3.2 Billing and renewal
Paid subscriptions are billed monthly through Stripe and renew automatically until canceled. You authorize us and Stripe to charge your payment method for applicable fees and taxes. You may manage payment methods, invoices, and cancellation through the Stripe Customer Portal linked from your account on the Website, subject to Stripe's terms.
All fees are non-refundable except where required by law or explicitly stated on the Website. Word credits do not roll over; unused credits expire at the end of the applicable subscription period unless we state otherwise.
3.3 Upgrades, downgrades, and cancellation
Upgrades may take effect immediately with prorated charges and adjusted credits as described at purchase. Downgrades and cancellations take effect at the end of the current billing period unless stated otherwise. No refunds for partial periods or unused credits upon cancellation.
Failure to pay may result in suspension or termination. We may change pricing or plans with notice; continued use after a price change constitutes acceptance of the new price for subsequent periods.
4. Export Controls, Sanctions & Geographic Restrictions
4.1 Sanctions, export controls, and restricted parties
You represent, warrant, and covenant that you (and any person or entity you authorize to use the Service or App) are not:
(a) Located in, a national or resident of, or accessing or using the Service or App from any comprehensively sanctioned jurisdiction under U.S. law (currently including Cuba, Iran, North Korea, Syria, and the Crimea, Donetsk, and Luhansk regions of Ukraine, or any other country or territory subject to comprehensive U.S. economic sanctions or embargoes administered by OFAC);
(b) Identified on the U.S. Treasury Department's Specially Designated Nationals and Blocked Persons List (SDN List) or any other list of sanctioned, prohibited, or restricted parties maintained by OFAC, BIS, or any other U.S. government agency;
(c) Subject to any other U.S. export control, sanctions, or trade restriction that would prohibit or restrict use of the Service or App.
The App and Service (including software download, subscription access, AI critique and rewrite features, and any data processing) are subject to U.S. export control laws, including the Export Administration Regulations (EAR), economic sanctions administered by OFAC, and possibly the International Traffic in Arms Regulations (ITAR). You must comply with all applicable U.S. and other export and import laws.
You will not export, re-export, download, or otherwise transfer the App, Service, or any related technology or data in violation of these laws or to any prohibited destination, end-user, or end-use.
4.2 Geographic availability and Unsupported Territories
We do not make the App, Website, or related services available in all countries and territories. We may restrict access from certain locations ("Unsupported Territories") for legal, regulatory, export-control, payment-processor, security, operational, or similar reasons, in our discretion. Unsupported Territories are enforced through technical and administrative measures and may change from time to time without notice. We are not obligated to publish a complete list of Unsupported Territories.
You are responsible for determining whether the service is available in your location before you access or use it. You agree to access and use the App and Website only where we make them available and not from any location where we block or restrict access. You will not use a VPN, proxy, or other means to circumvent geographic restrictions we enforce.
Word credits, subscription features, and AI usage are licensed only for use in permitted jurisdictions and by permitted users, as described in this Section and Section 3.
4.3 Enforcement
We may use geo-blocking, IP screening, account verification, and other technical measures to prevent access from comprehensively sanctioned jurisdictions, Unsupported Territories, and other restricted locations, and to enforce this Section. We reserve the right to immediately suspend or terminate any account that we reasonably believe violates (or is likely to violate) these restrictions, without notice or refund.
5. Your Content
5.1 Ownership
You retain all ownership rights in text, documents, and other materials you create or upload ("User Content"). We do not claim ownership of your User Content.
5.2 License to operate the service
You grant us a limited, non-exclusive, worldwide, royalty-free license to transmit and process User Content only as necessary to provide the App features you request, including AI-powered features. This license applies only for the duration needed to fulfill your request. We do not retain your writing on our remote systems as document storage; see our Privacy Policy for details.
5.3 Your responsibilities
You represent and warrant that:
- You own or have all rights necessary to use and submit User Content
- User Content does not violate any law or third-party rights (including copyright, trademark, privacy, or publicity rights)
- User Content is not unlawful, defamatory, harassing, or obscene, and complies with Section 7 (Acceptable Use)
You are solely responsible for backing up User Content. We are not a storage or archival service.
6. AI Features and Service Limitations
The App uses automated AI to provide writing-related assistance (such as feedback, analysis, and rewrites). You acknowledge and agree:
- AI outputs are generated algorithmically, may be inaccurate, incomplete, biased, or inappropriate, and are not guaranteed to be suitable for publication or any particular purpose
- Outputs are informational and creative assistance only — not professional editing, legal, financial, medical, or publishing advice
- We do not guarantee that use of the App will improve your writing, secure publication, or produce any specific result
- Obvious plagiarism may sometimes be flagged, but the App does not perform comprehensive plagiarism detection
- You must independently review all AI outputs before relying on or publishing them
- Critique and other AI features may require a minimum amount of input text and may be limited to certain languages (such as English). We may decline to run or complete a feature if input does not meet these requirements
- AI features may refuse or fail to process content for legal, safety, or technical reasons, including our AI provider's policies, export control, sanctions, and geographic restrictions under Section 4, and content prohibited under Section 7 (including material that sexualizes minors, even when submitted as fiction)
You use AI features at your sole risk. We are not liable for decisions you make based on AI outputs.
7. Acceptable Use
You agree not to:
(a) Use the App for any unlawful purpose or in violation of third-party rights
(b) Submit content that is illegal, infringing, harmful, or exploitative
(c) Submit content that sexualizes minors, including in fictional works
(d) Circumvent subscription limits, word credits, authentication, security, geo-blocking, IP screening, or other compliance measures
(e) Reverse engineer, decompile, disassemble, or attempt to derive source code from the App, except as permitted by applicable law
(f) Use bots, scrapers, or automation to access the service except through intended App interfaces
(g) Use the App to provide commercial editing, critique, or rewriting services to third parties for compensation
(h) Interfere with or disrupt the service or other users
(i) Access accounts or data that are not yours
(j) Access or use the App from a comprehensively sanctioned jurisdiction, from a location where we block or restrict the service, on behalf of a prohibited or restricted party, or in any manner that violates Section 4 (Export Controls, Sanctions & Geographic Restrictions), including by using a VPN, proxy, or other means to misrepresent your location or identity to evade those restrictions
(k) Misuse the Contact form or support channels (for example, by sending spam, malware, unlawful content, or false impersonation)
We may investigate violations and suspend or terminate access without refund.
8. Privacy and Data
Our Privacy Policy describes what information we collect, how we use it, and your choices. Our Cookie Policy describes cookies and similar technologies on the Website. Key points incorporated here:
- Your writing is stored on your device; we do not maintain copies of your writing in our remote databases
- AI features require sending your writing for processing to generate the response you requested
- Terms of Service acceptance records are retained as described in the Privacy Policy
- We may collect and use network and location-related information to comply with export control, sanctions, and geographic restrictions, as described in our Privacy Policy and Section 4
- Support requests may be submitted by email or through the signed-in Contact form on the Website, as described in our Privacy Policy and Section 15
Upon account termination or deletion, we handle data as described in the Privacy Policy, including archival of Terms of Service acceptance where applicable.
We take security seriously, but we cannot guarantee that unauthorized access, data breaches, or other security incidents will never occur. See our Privacy Policy for more detail.
9. Intellectual Property
The App, Website, software, branding, and documentation are owned by Dmesis, Inc. and protected by intellectual property laws. We grant you a limited, non-exclusive, non-transferable, revocable license to use the App for personal, non-commercial purposes during an active subscription, subject to these Terms and Section 4.
You may not copy, modify, distribute, sell, lease, or create derivative works of the App except as permitted by applicable law.
10. Third-Party Services
The App and Website rely on third-party service providers (such as for hosting, payments, email, AI processing, and optional sign-in). We do not control third-party services and are not responsible for their availability, acts, omissions, or policies.
Your use of AI and other features that involve third parties is also subject to Section 4 (Export Controls, Sanctions & Geographic Restrictions) and applicable U.S. export, sanctions, and geographic availability requirements. Third-party providers may impose their own geographic, sanctions, or export restrictions.
11. Disclaimers
THE APP AND WEBSITE ARE 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, ACCURACY, AND UNINTERRUPTED OR ERROR-FREE OPERATION.
WE DO NOT WARRANT THAT THE APP WILL MEET YOUR REQUIREMENTS, THAT YOUR DATA WILL BE FREE FROM UNAUTHORIZED ACCESS OR SECURITY BREACHES, OR THAT AI OUTPUTS WILL BE ERROR-FREE.
Some jurisdictions do not allow certain disclaimers; in those jurisdictions, disclaimers apply to the fullest extent permitted.
12. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY LAW, DMESIS, INC. AND ITS AFFILIATES, OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, AND LICENSORS WILL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR USE, ARISING FROM OR RELATED TO THESE TERMS OR THE APP, EVEN IF ADVISED OF THE POSSIBILITY.
OUR TOTAL AGGREGATE LIABILITY FOR ANY CLAIM ARISING FROM OR RELATED TO THESE TERMS OR THE APP WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU PAID US FOR THE APP IN THE TWELVE (12) MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM, OR (B) ONE HUNDRED U.S. DOLLARS ($100).
These limitations apply regardless of the theory of liability and even if a remedy fails its essential purpose.
We are not liable for: loss or corruption of User Content on your device; reliance on AI outputs; third-party service failures; unauthorized access or security incidents beyond our reasonable control; unauthorized account use resulting from your failure to safeguard credentials; or downtime, maintenance, or discontinuation of features.
Some jurisdictions do not allow certain limitations; in those jurisdictions, our liability is limited to the maximum extent permitted by law.
13. Indemnification
You agree to defend, indemnify, and hold harmless Dmesis, Inc. and its affiliates, officers, directors, employees, and agents from and against any claims, damages, losses, liabilities, costs, and expenses (including reasonable attorneys' fees) arising from or related to: (a) your User Content; (b) your use of the App; (c) your violation of these Terms (including Section 4) or applicable law; or (d) your violation of any third-party rights.
We may assume exclusive defense of any matter subject to indemnification at your expense; you will cooperate with our defense.
14. Service Availability and Changes
The App requires internet access. We may modify, suspend, or discontinue the App or any feature at any time, with or without notice. We are not liable for unavailability due to maintenance, updates, outages, or circumstances beyond our reasonable control.
15. Support
Support is provided on a reasonable-efforts basis through:
- Email at support@aibookeditor.com
- The signed-in Contact form on the Website (when logged in to your account)
When you use the Contact form, you must provide accurate information, acknowledge our Privacy Policy as prompted, and complete any required bot verification. Do not submit unlawful, infringing, or malicious content in messages or attachments. Optional attachments are limited to 10 MB. We do not guarantee response times or resolution of every issue. We generally respond to the email address associated with your account.
16. Termination
You may stop using the App and cancel your subscription at any time through account or billing settings (including the Stripe Customer Portal where available). Downgrades and cancellations take effect as described in Section 3.3.
You may delete your account through the self-service account-deletion flow on the Website when signed in (not from the desktop App). Account deletion requires authentication and bot verification. If you have a paid subscription that is still set to renew (or otherwise remains subject to further billing), you must first cancel that subscription through the Stripe Customer Portal (or other billing controls linked from your Website account) before account deletion will succeed. After you have canceled renewal — including when cancellation is scheduled for the end of the current billing period — you may delete your account even if the paid period has not yet ended. Deleting your account ends your license, forfeits unused word credits and remaining period access without refund (except where required by law), and does not by itself cancel billing with our payment processor; you remain responsible for canceling as described in Section 3. Payment and invoice records may remain with Stripe after your account is deleted.
We may suspend or terminate your access immediately for non-payment, violation of these Terms (including Section 4), or legal or security reasons, with or without notice and without refund where permitted by law.
Upon termination, your license ends, unused credits are forfeited without refund, and Sections that by nature should survive (including ownership, export controls and geographic restrictions, disclaimers, limitation of liability, indemnification, and governing law) will survive.
17. Governing Law and Disputes
These Terms are governed by the laws of the State of Delaware, United States, without regard to conflict-of-law rules.
Except where prohibited by law, you and Dmesis, Inc. agree that any dispute arising from or relating to these Terms or the App will be resolved exclusively in the state or federal courts located in the State of Delaware, and you consent to personal jurisdiction and venue in those courts.
18. Class Action and Jury Trial Waiver
TO THE MAXIMUM EXTENT PERMITTED BY LAW, YOU AND WE AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN YOUR OR ITS INDIVIDUAL CAPACITY AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, COLLECTIVE, OR REPRESENTATIVE PROCEEDING. YOU WAIVE ANY RIGHT TO A JURY TRIAL IN ANY DISPUTE ARISING FROM OR RELATING TO THESE TERMS OR THE APP, WHERE PERMITTED BY LAW.
If a court finds this Section unenforceable as to a particular claim, that claim may proceed in court and the remainder of this Section will still apply to the extent permitted.
19. General
These Terms, together with the Privacy Policy, Cookie Policy, and any plan-specific terms on the Website, are the entire agreement between you and us regarding the App and supersede prior agreements on that subject.
If any provision is held invalid or unenforceable, the remaining provisions remain in effect.
Our failure to enforce a provision is not a waiver. You may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition, or sale of assets.
Electronic communications and notices satisfy any legal notice requirement to the extent permitted by law.
