Acknowledgment

These are the Terms of Service governing the use of this Service and the agreement between You and the Company. These Terms set out the rights and obligations of all users regarding the use of the Service.

Your access to and use of the Service is conditioned on Your acceptance of and compliance with these Terms. These Terms apply to all visitors, users and others who access or use the Service.

By accessing or using the Service You agree to be bound by these Terms. If You disagree with any part of these Terms then You may not access the Service.

You represent that You are over the age of 18. The Company does not permit those under 18 to use the Service.

Your access to and use of the Service is also subject to Our Privacy Policy, which describes how We collect, use, and disclose personal information. Please read Our Privacy Policy carefully before using Our Service.

User Accounts

Most of the Service requires an Account. You may create an Account with an email address, a username and a password, or by signing in with Google or Apple.

When You create an Account with Us, You must provide Us information that is accurate, complete, and current at all times. Failure to do so constitutes a breach of the Terms, which may result in immediate termination of Your Account on Our Service.

You are responsible for safeguarding the password and any Personal Access Token that You use to access the Service and for any activities or actions under Your Account, whether Your password or token is with Our Service or a Third-Party Service. You agree not to disclose Your password or tokens to any third party. You must notify Us immediately upon becoming aware of any breach of security or unauthorized use of Your Account.

You may not use as a username the name of another person or entity or that is not lawfully available for use, a name or trademark that is subject to any rights of another person or entity other than You without appropriate authorization, or a name that is otherwise offensive, vulgar or obscene.

You may delete Your Account at any time from the Application's account settings or by contacting Us. Deleting Your Account permanently removes Your User Content, unpairs Your Displays, and cancels any active Subscription.

Subscriptions

Plans

The Service is offered on a Free Plan and a Pro Plan. What each plan includes — for example which AI features are available, how many images may be delivered to Displays per day, how many Personal Access Tokens You may hold, and how far back Your history reaches — is described in the Service and in Our developer documentation. The Free Plan may include a limited monthly trial of certain AI features. We may change what a plan includes, and will give You reasonable notice of changes that materially reduce what You have paid for.

The number of Displays You may pair with Your Account is not limited by plan. A Display You own keeps working on the Free Plan if Your Subscription ends.

Billing

The Pro Plan is billed in advance on a recurring monthly or yearly basis, depending on the billing interval You select at checkout. The price is shown at checkout and is charged in U.S. dollars. Your Subscription automatically renews at the end of each billing period under the same conditions unless You cancel it or the Company cancels it.

Payments are processed by Stripe. A valid payment method is required. By subscribing, You authorize the Company, through Stripe, to charge Your payment method for each billing period. Should automatic billing fail, We will keep Your Pro Plan active for a short grace period while the payment is retried; if payment still fails, Your Account returns to the Free Plan until payment is made.

Applicable taxes are added where required by law.

Cancellation

You may cancel Your Subscription at any time from the Subscription page of the Service, which opens Our billing portal. Cancellation takes effect at the end of the current billing period: You keep Pro Plan features until then, and You will not be charged again. Except where required by applicable law, fees already paid are non-refundable, and there are no refunds or credits for partial billing periods, unused allowances, or downgrades.

Fee changes

The Company, in its sole discretion and at any time, may modify the Subscription fees. Any Subscription fee change will become effective at the end of the then-current billing period.

The Company will provide You with reasonable prior notice of any change in Subscription fees to give You an opportunity to cancel Your Subscription before such change becomes effective. Your continued use of the Service after the Subscription fee change comes into effect constitutes Your agreement to pay the modified Subscription fee amount.

Promotion codes

The Company may offer promotion codes or introductory pricing. Each is subject to the conditions stated when it is offered, may be limited to new subscribers, and cannot be exchanged for cash.

Usage limits and fair use

Plan allowances and rate limits exist to keep the Service reliable for everyone. The Service may refuse or delay requests that exceed them. You agree not to circumvent allowances, for example by creating multiple Accounts or sharing Personal Access Tokens.

inklet Displays

inklet hardware is sold separately from the Service, under the purchase terms of the channel through which You buy it (for example, a crowdfunding campaign or Our store). Those terms, and any warranty that accompanies the hardware, are not part of these Terms.

Pairing a Display links it to Your Account. You may pair a Display only if You own it or have the owner's permission, and You may unpair it at any time from the Service. The Service delivers images to Displays over the internet and may deliver firmware updates to Displays to keep them secure and compatible; a Display may need such updates to keep working with the Service.

A Display shows what You and the Service send to it. Displays are not intended for safety-critical, medical, or time-critical uses, and You should not rely on a Display as Your only source of information that matters.

User Content

Your rights

You retain all rights in Your User Content. The Company does not claim ownership of it.

License to the Company

To provide the Service, You grant the Company a worldwide, non-exclusive, royalty-free license to host, store, copy, transmit, process, analyze, summarize, render, and display Your User Content, to create layouts and summaries derived from it, and to share it with the service providers who help Us do so (including hosting, link retrieval, and AI model providers), in each case solely to operate, secure, and improve the Service for You. This license ends when You delete the User Content or Your Account, except for copies that remain in backups for a limited time or where retention is required by law.

Your responsibilities

You are responsible for the User Content You submit and for keeping Your own copies of it. The Service is not designed as a backup system. You represent and warrant that You own or have the necessary rights to Your User Content, and that submitting it does not violate the law or the rights of any person.

The Company does not review User Content before it is stored or shown, but may remove or refuse to process User Content that violates these Terms, and may suspend Accounts that repeatedly do so.

Retention and deletion

You can delete individual items of User Content from the Service. Deleted files are removed from active systems promptly and from backups within a limited period, as described in Our Privacy Policy.

AI Features

The Service uses artificial intelligence to read Your User Content, fetch the pages behind links You send, describe images, choose a Display, produce summaries, and lay out what appears on a Display. To do this, the Company sends the relevant User Content to third-party AI model providers acting on Our behalf.

AI output can be incomplete, outdated, or wrong. It is generated automatically, is not reviewed by a person, and is not advice of any kind. You are responsible for reviewing what is shown on Your Displays before relying on it. The Company does not guarantee that any AI feature will remain available, produce a particular result, or work with any particular content.

AI features may be limited to the Pro Plan or subject to allowances, as described in the Service.

Developer API and SDK

You may call the API and use the SDK with a Personal Access Token created in Your Account. A Personal Access Token acts as You: anything done with it counts as done by You and consumes Your Account's allowances. Keep Your tokens secret, never place them in client-side or public code, and revoke a token immediately if You believe it has been exposed.

The API and SDK may be used only to build applications and integrations that work with the Service for Your own Displays or for users who have authorized You. You may not use them to resell or provide the Service to third parties, to exceed rate limits, or to access data You are not authorized to access.

The SDK is provided under the license that accompanies it; where none is stated, it is provided under these Terms. The Company may change or discontinue API endpoints and SDK versions, and will make reasonable efforts to give notice of changes that break existing integrations.

Intellectual Property

The Service and its original content (excluding User Content), features and functionality are and will remain the exclusive property of the Company and its licensors. The Service is protected by copyright, trademark, and other laws of both the Country and foreign countries. The inklet name, logo, and product names are trademarks of the Company and may not be used in connection with any product or service without the prior written consent of the Company.

Subject to these Terms, the Company grants You a limited, non-exclusive, non-transferable, revocable license to install and use the Application on Devices You own or control, solely to use the Service. You may not copy, modify, distribute, sell, or lease any part of the Service; reverse engineer or attempt to extract the source code of the Service, except to the extent permitted by law or by an open-source license that applies to a component; or remove any proprietary notices.

The Service includes open-source software components. Those components are licensed under their own terms, which take precedence over these Terms for those components.

Your Feedback to Us

You assign all rights, title and interest in any Feedback You provide the Company. If for any reason such assignment is ineffective, You agree to grant the Company a non-exclusive, perpetual, irrevocable, royalty free, worldwide right and license to use, reproduce, disclose, sub-license, distribute, modify and exploit such Feedback without restriction and without compensation or credit to You.

Acceptable Use

You agree not to use the Service:

  • In any way that violates any applicable law or regulation.
  • To submit User Content that is unlawful, infringing, defamatory, or that You do not have the right to share, or that contains malware.
  • For the purpose of exploiting, harming, or attempting to exploit or harm minors in any way.
  • To impersonate the Company, a Company employee, another user, or any other person or entity.
  • To access, tamper with, or use non-public areas of the Service, the Company's systems, or the systems of Our providers, or to probe, scan, or test the vulnerability of any system without authorization.
  • To interfere with the proper working of the Service, including by overloading, flooding, or attacking it, or by circumventing allowances, rate limits, or plan restrictions.
  • To pair, control, or send content to a Display You do not own or are not authorized to use.
  • To resell, rent, or provide the Service to third parties, or to build a competing product using Our non-public information.
  • To collect data from the Service by automated means other than through the API as permitted by these Terms.

Software Updates

The Application may check for, download, and install updates automatically, and Displays may receive firmware updates over the air. Updates may add, change, or remove features. You may need to install an update to keep using the Service. By using the Service, You consent to receiving such updates.

Third-Party Services and Links

The Service works with, links to, or relies on services that are not owned or controlled by the Company, including sign-in with Google and Apple, payment processing by Stripe, software distribution and updates through GitHub, weather data from Open-Meteo and Apple Weather, community spaces such as Discord, and crowdfunding platforms such as Kickstarter.

The Company has no control over, and assumes no responsibility for, the content, privacy policies, or practices of any Third-Party Service. You further acknowledge and agree that the Company shall not be responsible or liable, directly or indirectly, for any damage or loss caused or alleged to be caused by or in connection with the use of or reliance on any such content, goods or services available on or through any Third-Party Service.

We strongly advise You to read the terms and conditions and privacy policies of any Third-Party Service that You use.

Links from a Third-Party Social Media Service

The Service may display, include, make available, or link to content or services provided by a Third-Party Social Media Service. A Third-Party Social Media Service is not owned or controlled by the Company, and the Company does not endorse or assume responsibility for any Third-Party Social Media Service.

You acknowledge and agree that the Company shall not be responsible or liable, directly or indirectly, for any damage or loss caused or alleged to be caused by or in connection with Your access to or use of any Third-Party Social Media Service, including any content, goods, or services made available through them. Your use of any Third-Party Social Media Service is governed by that Third-Party Social Media Service's terms and privacy policies.

Apple App Store Additional Terms

If You download the Application from the Apple App Store, the following also applies. These Terms are between You and the Company only, and not with Apple Inc. ("Apple"); Apple is not responsible for the Application or its content. Apple has no obligation to provide maintenance or support for the Application. To the extent any warranty applies and is not disclaimed, You may notify Apple, and Apple's only obligation will be to refund the purchase price, if any, of the Application. Apple is not responsible for addressing any claims by You or a third party relating to the Application, including product liability claims, claims that the Application fails to conform to legal or regulatory requirements, or consumer protection claims. In the event of a third-party claim that the Application infringes intellectual property rights, the Company, not Apple, is responsible for its investigation, defense, settlement and discharge. You must comply with Apple's App Store terms of service when using the Application. Apple and its subsidiaries are third-party beneficiaries of these Terms with respect to the Application and may enforce them against You.

Termination

We may terminate or suspend Your Account and access to the Service immediately, without prior notice or liability, for any reason whatsoever, including without limitation if You breach these Terms or if We are required to do so by law. Where practical, We will give You notice and an opportunity to retrieve Your User Content.

You may stop using the Service and delete Your Account at any time.

Upon termination, Your right to use the Service will cease immediately, Your Subscription will be cancelled, and Your User Content will be deleted in accordance with Our Privacy Policy. Provisions that by their nature should survive termination — including Intellectual Property, Your Feedback to Us, Indemnification, Limitation of Liability, the Disclaimer, Governing Law and Disputes Resolution — survive.

The Company may also discontinue the Service, or any part of it, at any time. If We discontinue a paid part of the Service, We will refund the pro-rated unused portion of Your Subscription.

Indemnification

You agree to defend, indemnify and hold harmless the Company and its officers, members, employees, contractors, and suppliers from and against any claims, damages, and expenses (including reasonable attorneys' fees) arising out of Your User Content, Your use of the Service in violation of these Terms, or Your violation of any law or the rights of a third party.

Limitation of Liability

Notwithstanding any damages that You might incur, the entire liability of the Company and any of its suppliers under any provision of these Terms and Your exclusive remedy for all of the foregoing shall be limited to the amount actually paid by You through the Service in the 12 months before the claim arose, or 100 USD if You haven't purchased anything through the Service.

To the maximum extent permitted by applicable law, in no event shall the Company or its suppliers be liable for any special, incidental, indirect, or consequential damages whatsoever (including, but not limited to, damages for loss of profits, loss of data or other information, for business interruption, for personal injury, loss of privacy arising out of or in any way related to the use of or inability to use the Service, third-party software and/or third-party hardware used with the Service, or otherwise in connection with any provision of these Terms), even if the Company or any supplier has been advised of the possibility of such damages and even if the remedy fails of its essential purpose.

Some states do not allow the exclusion of implied warranties or limitation of liability for incidental or consequential damages, which means that some of the above limitations may not apply. In these states, each party's liability will be limited to the greatest extent permitted by law.

"AS IS" and "AS AVAILABLE" Disclaimer

The Service is provided to You "AS IS" and "AS AVAILABLE" and with all faults and defects without warranty of any kind. To the maximum extent permitted under applicable law, the Company, on its own behalf and on behalf of its Affiliates and its and their respective licensors and service providers, expressly disclaims all warranties, whether express, implied, statutory or otherwise, with respect to the Service, including all implied warranties of merchantability, fitness for a particular purpose, title and non-infringement, and warranties that may arise out of course of dealing, course of performance, usage or trade practice. Without limitation to the foregoing, the Company provides no warranty or undertaking, and makes no representation of any kind that the Service will meet Your requirements, achieve any intended results, be compatible or work with any other software, applications, systems or services, operate without interruption, meet any performance or reliability standards or be error free or that any errors or defects can or will be corrected.

Without limiting the foregoing, neither the Company nor any of the Company's providers makes any representation or warranty of any kind, express or implied: (i) as to the operation or availability of the Service, or the information, content, and materials or products included thereon; (ii) that the Service will be uninterrupted or error-free; (iii) as to the accuracy, reliability, or currency of any information or content provided through the Service, including AI-generated content; or (iv) that the Service, its servers, the content, or e-mails sent from or on behalf of the Company are free of viruses, scripts, trojan horses, worms, malware, timebombs or other harmful components.

Some jurisdictions do not allow the exclusion of certain types of warranties or limitations on applicable statutory rights of a consumer, so some or all of the above exclusions and limitations may not apply to You. But in such a case the exclusions and limitations set forth in this section shall be applied to the greatest extent enforceable under applicable law.

Governing Law

The laws of the Country/State, excluding its conflicts of law rules, shall govern these Terms and Your use of the Service. Your use of the Application may also be subject to other local, state, national, or international laws.

Disputes Resolution

If You have any concern or dispute about the Service, You agree to first try to resolve the dispute informally by contacting the Company at the email address below. If the dispute is not resolved within 60 days, either party may bring it before the state or federal courts located in Cook County, Illinois, and You consent to the personal jurisdiction of those courts. Either party may instead bring an eligible claim in small claims court. Nothing in this section limits rights that mandatory consumer law gives You in Your place of residence.

For European Union (EU) Users

If You are a European Union consumer, You will benefit from any mandatory provisions of the law of the country in which You are resident.

United States Legal Compliance

You represent and warrant that (i) You are not located in a country that is subject to the United States government embargo, or that has been designated by the United States government as a "terrorist supporting" country, and (ii) You are not listed on any United States government list of prohibited or restricted parties.

Severability and Waiver

Severability

If any provision of these Terms is held to be unenforceable or invalid, such provision will be changed and interpreted to accomplish the objectives of such provision to the greatest extent possible under applicable law and the remaining provisions will continue in full force and effect.

Waiver

Except as provided herein, the failure to exercise a right or to require performance of an obligation under these Terms shall not affect a party's ability to exercise such right or require such performance at any time thereafter nor shall the waiver of a breach constitute a waiver of any subsequent breach.

Translation Interpretation

These Terms may have been translated if We have made them available to You on Our Service. You agree that the original English text shall prevail in the case of a dispute.

Changes to These Terms of Service

We reserve the right, at Our sole discretion, to modify or replace these Terms at any time. If a revision is material We will make reasonable efforts to provide at least 30 days' notice prior to any new terms taking effect. What constitutes a material change will be determined at Our sole discretion.

By continuing to access or use Our Service after those revisions become effective, You agree to be bound by the revised terms. If You do not agree to the new terms, in whole or in part, please stop using the Service.
