Terms of Service

These Terms of Service explain the rules for using BlindBox, including who can use the service, how accounts and subscriptions work, how third-party providers fit in, and the limits that apply when you use the website, apps, downloads, and related services.

Effective date: May 11, 2026

1. Acceptance of these terms

These Terms of Service govern your use of the BlindBox website, apps, downloads, APIs, documentation, support tools, and related services.

  • By accessing or using BlindBox, you agree to these Terms and to our Privacy Policy.
  • If you use BlindBox on behalf of an organization, you represent that you have authority to bind that organization to these Terms.
  • If you do not agree to these Terms, do not use BlindBox.

2. What BlindBox provides

BlindBox is an accessibility-focused software and service offering designed to help users work with existing email and calendar providers.

  • BlindBox may include a marketing website, downloadable desktop and mobile software, account and support services, billing tools, donation flows, accessibility features, attachment-analysis features, and related documentation.
  • BlindBox does not replace your underlying email provider, calendar provider, internet connection, device operating system, assistive technology, or payment provider. Those services remain separate from BlindBox even when they integrate with it.
  • Because parts of BlindBox depend on local device capabilities and third-party services, available features may differ by platform, operating system, region, provider, or plan tier.

3. Eligibility

You must be legally able to enter into these Terms in order to use BlindBox.

  • You must be at least 13 years old to use BlindBox.
  • If you are under the age of majority where you live, you may use BlindBox only with any permission required by applicable law.
  • You may not use BlindBox if your use would violate applicable law, sanctions, export controls, or the rights of another person.

4. Accounts and account security

Some BlindBox features require an account or connected mailbox session.

  • You agree to provide accurate information and to keep your account details reasonably current.
  • You are responsible for maintaining the confidentiality of your BlindBox credentials, connected mailbox credentials, and access to your devices.
  • You are responsible for all activity that occurs through your account or connected sessions unless caused by our breach of these Terms or applicable law.
  • You must notify us promptly if you believe your account, device, or connected provider access has been compromised.

5. Electronic communications

Using BlindBox may involve communications that are necessary to operate the service or complete transactions you request.

  • You agree that BlindBox may send you transactional or service-related communications such as account notices, verification codes, password-reset messages, billing notices, support responses, and policy updates through email, in-app notices, or other reasonable channels.
  • You are responsible for keeping your contact information current enough to receive important service communications.
  • Nothing in this section requires BlindBox to send marketing communications, and where marketing messages are sent they remain subject to applicable consent and unsubscribe rules.

6. License to use BlindBox

Subject to these Terms, BlindBox gives you a limited right to use the service.

  • We grant you a limited, non-exclusive, non-transferable, revocable license to access and use BlindBox for your personal use or internal business use.
  • These Terms govern your use of the hosted BlindBox service, website, downloads, and related materials unless a separate written agreement says otherwise.
  • If any part of BlindBox software, source code, or related material is offered under a separate open-source or other written license, that separate license controls your rights for that material.
  • Except to the extent a separate license or applicable law permits otherwise, you may not use BlindBox in a way that copies, exploits, resells, or redistributes the service itself beyond ordinary permitted use.

7. Third-party services and connected accounts

BlindBox works with third-party providers that you choose to connect or use.

  • Your use of Gmail, Microsoft 365, Outlook, Apple, Polar, custom IMAP services, and other third-party services remains subject to those providers’ terms and privacy policies.
  • BlindBox is not responsible for outages, access restrictions, billing decisions, policy changes, API limits, account suspensions, or content decisions made by third-party providers.
  • Some BlindBox features may stop working, work differently, or be unavailable if a third-party provider changes its systems, permissions, APIs, or business rules.

8. Your content and permissions

BlindBox needs limited permission to handle the content and data you choose to use with the service.

  • As between you and BlindBox, you retain rights in your email, attachments, account information, support submissions, and other content that belongs to you or that you are authorized to use.
  • You give BlindBox the limited rights necessary to host, transmit, store, format, display, cache, synchronize, analyze, and otherwise process that content solely to provide and improve the service features you choose to use, comply with law, and protect the service.
  • You represent that you have the rights, permissions, and legal basis necessary to connect accounts and submit content through BlindBox and that doing so will not violate law, contract, or the rights of another person.

9. AI and attachment analysis features

BlindBox may offer optional AI-powered accessibility features for attachments and related content.

  • AI features are optional and may require a paid plan, available quota, and supported file types.
  • By using an AI feature, you authorize BlindBox to process the relevant attachment or content and send it to the configured AI provider to generate summaries, transcripts, or other outputs.
  • AI output can be incomplete, inaccurate, or misleading. You should review important results before relying on them for legal, medical, financial, employment, educational, accessibility-critical, or other high-stakes decisions.
  • You remain responsible for ensuring that you have the right to submit content to BlindBox and any connected provider for processing.

10. Acceptable use

You may not use BlindBox in a way that is unlawful, harmful, abusive, or disruptive.

  • Do not use BlindBox to violate law, infringe intellectual property or privacy rights, impersonate others, distribute malware, or interfere with the security or availability of the service.
  • Do not attempt to gain unauthorized access to BlindBox systems, other users’ accounts, connected provider accounts, or data you are not authorized to access.
  • Do not use BlindBox to send spam, bulk unsolicited communications, fraudulent messages, or harmful content in violation of provider rules or applicable law.
  • Do not misuse the website, apps, downloads, APIs, or support channels in a way that could damage BlindBox, our users, or third parties.

11. Subscriptions, trials, and donations

BlindBox may offer paid subscriptions, trials, and optional donations through third-party billing tools.

  • Prices, plan features, trial availability, and usage limits may change prospectively. The pricing and feature details shown at the time of purchase or renewal control for that transaction.
  • If you begin a paid subscription or monthly donation, you authorize recurring charges at the cadence you selected until cancellation takes effect.
  • If you enroll in a free trial, promotional period, or other negative-option offer that converts into a paid plan, you authorize the recurring charges disclosed at sign-up unless you cancel before the disclosed renewal or billing date, subject to applicable law.
  • Trials, promotional offers, discounts, and complimentary access may be limited by account, region, eligibility, time period, or provider rules.
  • Subscription management, billing updates, cancellation, and payment collection may occur through our payment provider’s checkout and customer-portal tools.
  • Except where required by law, expressly stated in an offer, or otherwise determined by BlindBox or the payment provider in a particular case, payments are generally non-refundable once charged for the applicable billing period or donation transaction.
  • Taxes, bank fees, carrier fees, and currency conversion charges may apply depending on your location and payment method.
  • If a payment fails or your account becomes past due, BlindBox may limit or suspend paid features until billing is resolved.

12. Cancellation and account closure

You should be able to stop using BlindBox and end recurring paid commitments in a way that is reasonably understandable and practical.

  • You may cancel a paid subscription using the billing or customer-portal method made available for that subscription, subject to the timing and renewal rules disclosed at sign-up and during checkout.
  • Canceling a subscription generally stops future renewals but does not automatically erase your BlindBox account, connected provider accounts, or records that we are entitled or required to keep.
  • If you want your BlindBox account deleted, you should request deletion separately unless the service explicitly states that cancellation and deletion are combined.

13. Availability, updates, and support

We are always working to improve BlindBox, but we cannot promise uninterrupted availability.

  • BlindBox may change, add, remove, suspend, or discontinue features at any time, including features that depend on third-party integrations or accessibility tooling.
  • The service may be unavailable because of maintenance, outages, connectivity problems, software defects, provider changes, security incidents, or events outside our reasonable control.
  • We may release updates, patches, or configuration changes that are necessary for security, compatibility, legal compliance, or product improvement.

14. Intellectual property

BlindBox and its related materials are protected by intellectual property laws.

  • BlindBox retains all rights, title, and interest in the website, apps, software, documentation, visual design, trademarks, logos, and related content, except for third-party materials that remain owned by their respective holders.
  • You retain rights in content that belongs to you, but you grant BlindBox the limited rights needed to host, transmit, process, display, and analyze that content to operate the service features you choose to use.

15. Feedback and suggestions

BlindBox is built with user input in mind, and we appreciate ideas for improvement.

  • If you send feedback, suggestions, bug reports, accessibility ideas, feature requests, or other comments about BlindBox, you grant us a non-exclusive, worldwide, royalty-free license to use, reproduce, modify, adapt, publish, and incorporate that feedback into the service without separate compensation to you.
  • This feedback license does not take ownership of your content generally; it only covers the ideas and feedback you choose to provide about BlindBox and related services.

16. Suspension and termination

We may suspend or end access when necessary to protect BlindBox, users, or third parties.

  • We may suspend, restrict, or terminate access if we reasonably believe you violated these Terms, created security or abuse risk, failed to pay applicable fees, or used BlindBox in a way that could create legal exposure.
  • You may stop using BlindBox at any time. If you want account deletion, contact us or use any deletion process we make available.
  • Termination does not eliminate obligations that by their nature should survive, including payment obligations incurred before termination, intellectual property provisions, disclaimers, liability limits, and dispute-related provisions.

17. Disclaimers

To the maximum extent permitted by law, BlindBox is provided on an "as is" and "as available" basis.

  • We disclaim warranties of merchantability, fitness for a particular purpose, non-infringement, and any warranty that the service will be uninterrupted, error-free, completely secure, or compatible with every provider, device, platform, or assistive-technology setup.
  • We do not guarantee the accuracy of AI-generated summaries, transcripts, or other automated outputs.
  • BlindBox does not provide legal, medical, financial, accounting, or other professional advice through the service.

18. Limitation of liability

To the maximum extent permitted by law, BlindBox’s liability is limited.

  • BlindBox will not be liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for loss of profits, revenues, goodwill, data, or business opportunities arising from or related to your use of the service.
  • To the maximum extent permitted by law, BlindBox’s total liability for claims arising out of or relating to the service will not exceed the greater of the amounts you paid to BlindBox for the relevant service during the 12 months before the event giving rise to the claim or $100 USD.
  • Nothing in these Terms limits liability that cannot be limited under applicable law.

19. Consumer protections and non-waivable rights

These Terms should be read consistently with the consumer-protection laws that apply to you.

  • Nothing in these Terms is intended to waive rights or remedies that cannot lawfully be waived under applicable consumer-protection, subscription, privacy, or accessibility law.
  • If a mandatory law gives you rights that are broader than a provision in these Terms, that mandatory law controls to the extent of the conflict.

20. Events outside our reasonable control

Sometimes service interruptions or delays happen for reasons no one can reasonably control.

  • BlindBox will not be responsible for delay, interruption, or failure to perform caused by events beyond our reasonable control, including internet outages, provider outages, acts of government, labor disputes, security incidents, natural disasters, civil unrest, war, pandemics, or infrastructure failures.
  • This section does not excuse obligations that applicable law does not allow to be excused.

21. General legal terms

These additional contract rules help explain how the rest of the Terms operate.

  • If a court or regulator determines that one provision of these Terms is unenforceable, the remaining provisions will remain in effect to the extent permitted by law.
  • BlindBox’s failure to enforce a provision of these Terms is not a waiver of that provision or of any other rights.
  • You may not assign or transfer your rights or obligations under these Terms without BlindBox’s consent, except where applicable law prevents that restriction. BlindBox may assign these Terms in connection with a merger, acquisition, reorganization, or sale of assets.
  • These Terms, together with any policies or additional terms expressly incorporated by reference, form the current agreement between you and BlindBox regarding the service, except where a separate written agreement or separate open-source license governs specific materials.

22. Changes to these terms

We may update these Terms from time to time.

  • When we make material changes, we will update the effective date on this page and may provide additional notice where appropriate.
  • Your continued use of BlindBox after updated Terms take effect means you accept the revised Terms.
