Terms of Service

1. Acceptance and Authority

These Terms of Service ("Terms") form a binding agreement between you and Avora Technologies Limited, trading as Braille Link ("Braille Link", "we", "us", or "our"), for use of the Braille Link websites, applications, backend APIs, dashboards, workspace tools, translation tools, institution tools, billing flows, and related browser extensions, and related services (together, the "Service").

Avora Technologies Limited owns and operates Braille Link. References to "Braille Link", "we", "us", or "our" in these Terms mean Avora Technologies Limited acting through the Braille Link platform.

You accept these Terms when you create an account, sign in, accept an invitation, click to accept the Terms, use the Service, submit content, select a subscription, pay for a plan, or access the Service through an institution or programme. If you do not agree, you must not use the Service.

If you use the Service for a school, university, company, nonprofit, government body, ministry programme, donor programme, or other organisation, you represent that you have authority to bind that organisation and its authorised users. If you do not have that authority, you must use the Service only in your individual capacity and you must not create or manage institution, tenant, learner, billing, or programme records.

These Terms do not limit statutory rights that cannot be excluded, waived, or limited by contract. If a provision cannot lawfully apply to you, it will apply only to the maximum extent permitted by law.

2. The Service

Braille Link is an accessibility and education platform that helps users enter, translate, review, save, submit, export, and administer Braille-related content. The Service includes the following current or configurable features:

• Braille Unicode to text translation and text to Braille translation using configured Braille tables.
• Perkins-style input, on-screen keyboard support, speech preview, and browser text-to-speech settings.
• The Braille Link Keyboard browser extension, where available, for Perkins-style Braille entry, speech feedback, and navigation support on external websites outside the Braille Link web app.
• Workspace autosave, saved sessions, import/export of supported account data, and local browser preferences.
• PDF, DOCX, BRF, and text-related export or download features where enabled.
• Document transcription for supported PDF, DOCX, TXT, and BRF files, subject to size and extraction limits.
• Document Reader features that extract readable text from uploaded documents, generate audio narration, divide documents into playable sections, and save listening progress where enabled.
• Image or camera-based Braille detection through a vision service where OCR/upload features are enabled.
• User accounts, email verification, password reset, MFA, security questions, passkeys, sessions, and device controls.
• Institution, tenant, programme, rollout, invitation, learner submission, role, permission, and workspace-access management.
• Billing, trials, grace periods, plan selection, subscription status, payment gateway settings, callbacks, and webhooks.
• Root owner, super admin, admin, programme admin, institution admin, and tenant manager controls.
• Security events, audit logs, rate-limit policies, data-retention policies, approvals, notification templates, and emergency controls.

We may add, remove, suspend, rename, redesign, limit, or replace features. Some features may be available only to certain roles, tenants, programmes, plans, browsers, devices, countries, or deployment environments. Development, demo, middle, or staging environments may behave differently from production.

The browser extension is an optional companion to the Service. It may require an authenticated Braille Link account, an active feature entitlement, browser-store distribution, browser permissions, and a supported browser. On Braille Link pages, the native Braille input and native text-to-speech systems remain responsible for keyboard capture and speech behavior. On external websites, you remain responsible for how you use the extension, including compliance with the rules of the site where you type.

Extension permissions may include browser storage for settings and connection state, tab access to connect the popup to the active Braille Link session and update open tabs, alarms for entitlement refresh, Braille Link host permissions for account and entitlement checks, and content scripts on external pages so keyboard, speech-feedback, and navigation features can work in supported text fields.

3. Eligibility and User Responsibility

You must provide accurate information and use the Service only for lawful educational, accessibility, administrative, research, or internal business purposes. You are responsible for your users, devices, network, uploaded materials, browser storage, account settings, and all activity under your account or institution account.

The Service is designed for supervised educational and institutional use. It is not intended for unsupervised direct use by children, and it is not a consumer social network or public file-hosting service. If you invite or authorise minors or learners, you must ensure that appropriate notices, consents, safeguards, and lawful bases are in place.

You must not rely on the Service as the sole method for legally required accessibility accommodation, exam marking, medical decision-making, legal advice, safety-critical communication, emergency response, or official record creation. Human review is required before using outputs for important decisions.

4. Accounts, Credentials, and Security

4.1 Account Information

Account records may include your name, email address, username, display name, phone number, registration number, role, institution, tenant, programme, avatar, profile text, onboarding status, subscription status, access identifier, terms acceptance, security status, and other account details needed to provide the Service.

4.2 Credential Protection

You are responsible for protecting passwords, MFA codes, backup codes, passkeys, devices, session tokens, recovery answers, and browser sessions. Use a strong, unique password; enable available MFA or passkeys for privileged roles; and log out on shared devices. Sharing accounts or credentials is prohibited unless we expressly approve a managed service account in writing.

4.3 Security Controls

We may enforce or offer email verification, password policies, force-password-reset flags, failed-login lockouts, MFA recovery, security-question fallback, passkey enrollment, session revocation, device blocking, IP or device limits, role checks, tenant checks, rate limits, audit logging, and security challenges.

You must notify us promptly at support@tusomebraille.com if you suspect unauthorised access, credential compromise, misdirected invitations, incorrect role assignment, tenant ownership errors, or misuse of learner data.

5. Institutions, Tenants, Programmes, and Learners

Institution and tenant features are designed for schools, programmes, organisations, and managed groups. Administrators may create or manage users, invitations, co-admin status, workspace access, Braille access, passwords, learner submissions, tenant ownership, managers, seat limits, risk settings, billing enforcement, programme attachment, and rollout membership.

Institutions are responsible for:

• Ensuring administrators are authorised and trained before receiving privileged access.
• Assigning the least privileges needed and removing users who no longer need access.
• Providing all notices, consents, approvals, procurement authorisations, and lawful bases required for learners, staff, guardians, and institutional records.
• Ensuring learner content is submitted, reviewed, exported, retained, and deleted according to institutional policy and applicable law.
• Complying with education-record, child privacy, accessibility, disability, procurement, public-sector, grant, tax, and data-protection laws that apply to the institution.
• Responding to learner, parent, guardian, staff, regulator, or sponsor requests where the institution controls the relevant records.

Tenant owners and institution administrators may have special responsibilities. Some deletion or ownership changes cannot be completed until ownership, billing, pending approvals, learner records, audit needs, or legal retention requirements are resolved.

Where Braille Link processes institutional learner data on behalf of an institution, we will process that data to provide, secure, support, and administer the Service, subject to these Terms, our Privacy Policy, any applicable signed data processing terms, and applicable law.

6. User Content, Outputs, and Human Review

6.1 Your Content

"Your Content" means content you or your authorised users submit, upload, type, save, import, export, or transmit through the Service, including Braille input, text input, workspace sessions, message history, learner submissions, uploaded documents, uploaded images, camera captures, file names, profile content, feedback, support communications, browser-extension settings and entitlement checks, and generated outputs.

You are responsible for ensuring that you have the rights and permissions required to submit Your Content, including content that contains personal data, student records, copyrighted works, confidential information, images, documents, or accessibility-related information.

6.2 Licence to Operate the Service

You retain ownership of Your Content. You grant Braille Link a limited, worldwide, non-exclusive, royalty-free licence to host, store, copy, process, transmit, display, generate, export, download, back up, secure, delete, and otherwise use Your Content only as needed to provide, maintain, secure, support, audit, improve, and administer the Service.

6.3 Outputs

Translation, document, image, browser-extension speech feedback, navigation feedback, speech-preview, and export outputs may contain errors, omissions, formatting issues, table-selection mismatches, OCR mistakes, orientation mistakes, transcription mistakes, speech pronunciation errors, or low-confidence results. Outputs are tools for assistance and review, not guarantees.

Where Document Reader is enabled, generated narration, extracted text, document sections, audio segments, segment titles, previews, durations, and playback progress may be created from uploaded documents. These outputs may misread, omit, reorder, or mispronounce content, especially where source documents are scanned, image-heavy, poorly formatted, encrypted, corrupted, or contain tables, mathematical notation, handwriting, unusual fonts, or low-quality text extraction.

6.4 Restricted Content

Do not submit unlawful, harmful, exploitative, infringing, malicious, or highly sensitive content unless your use is lawful, necessary, authorised, and protected by appropriate safeguards. The Service is not designed to store full medical records, national identity scans, financial account credentials, biometric images for identification, or confidential state secrets.

7. Acceptable Use and Prohibited Conduct

Our Acceptable Use Policy is incorporated into these Terms. You must not:

• Break the law, violate another person's rights, or misuse learner, guardian, staff, or institution data.
• Bypass authentication, access controls, role limits, tenant isolation, billing controls, feature flags, or rate limits.
• Upload malware, exploit payloads, adversarial images, abusive content, illegal content, or files intended to disrupt the Service.
• Probe, scan, scrape, reverse engineer, overload, resell, sublicense, or bulk-extract the Service without written authorisation.
• Use the Service to surveil, profile, discriminate against, harass, or make automated high-impact decisions about learners or vulnerable people.
• Misrepresent affiliation with Braille Link, an institution, programme, government body, sponsor, or payment provider.
• Use another person's account, invite users without authority, or keep access after leaving an institution.

We may investigate suspected violations and may preserve related records where needed for security, legal, audit, billing, or institutional accountability purposes.

8. Subscriptions, Trials, Billing, and Payment Gateways

Paid plans, trials, grace periods, seat limits, billing enforcement, institution plans, personal plans, government or donor programmes, and feature entitlements are described in the Service, in an invoice, in an order form, or in a separate signed agreement. Fees may be charged in advance unless otherwise agreed.

Payment processing may be handled through third-party payment gateways such as Pesapal where enabled. Payment gateways may collect, process, retain, and disclose payment information under their own terms and privacy notices. Braille Link is not intended to store full card numbers, mobile money PINs, or payment credentials.

You are responsible for taxes, withholding, bank charges, mobile-money charges, gateway fees, incorrect billing details, chargebacks, and unauthorised payment activity caused by your account or institution unless applicable law says otherwise. If payment fails, we may apply configured grace periods, retry or verify payment status, restrict paid features, suspend access, or cancel a subscription.

Refund and cancellation rules are in our Refund and Cancellation Policy, unless a signed agreement states otherwise.

9. Third-Party Services and Open-Source Components

The Service may depend on third-party services and open-source components, including hosting providers, databases, deployment providers, browser-extension stores, payment gateways, email delivery systems, browser APIs, operating-system passkey providers, PDF/DOCX processing libraries, Liblouis Braille tables, computer-vision services, logging or monitoring tools, and internet service providers.

Third-party services may be unavailable, delayed, misconfigured, changed, discontinued, or subject to their own terms. We are not responsible for third-party acts or omissions beyond our reasonable control, but we will use reasonable efforts to choose providers appropriate for the Service.

Open-source software remains subject to its applicable open-source licences. These Terms do not restrict any rights you have directly under those licences.

10. Privacy, Data Protection, and Student Records

Our Privacy Policy explains how we collect, use, disclose, retain, and protect personal data. By using the Service, you acknowledge the Privacy Policy.

Institutions remain responsible for their own notices, lawful bases, consents, records of processing, data-subject request handling, student-record duties, procurement requirements, and guardian communications where they determine the purpose and means of processing. Braille Link remains responsible for its own legal duties and will not use these Terms to disclaim responsibilities that cannot lawfully be shifted.

If a data processing agreement is legally required for an institution, procurement, government body, or regulated education deployment, the institution must request and complete appropriate data processing terms before uploading regulated production learner data at scale.

11. Accessibility, Accommodation, and Availability

Braille Link is built to support accessibility and inclusive education, but it does not replace an institution's legal duty to provide reasonable accommodation, accessible materials, trained support staff, assistive technology, accessible assessments, or alternative access where required by law.

We aim to improve usability and accessibility over time. However, accessibility can depend on device, browser, screen reader, network, input method, Braille table, document quality, image quality, user training, and institutional workflow. Report accessibility barriers to support@tusomebraille.com.

Availability commitments, support targets, and service credits, if any, are governed by our Service Level Agreement or by a signed agreement. Unless such agreement applies, the Service is provided without any uptime guarantee.

12. Security, Audit Logs, and Incident Response

We use technical and organisational safeguards designed to protect the Service, including account security controls, role-based access, tenant scoping, audit logs, session controls, device controls, rate limits, secure password storage, email verification, MFA, passkeys, and operational monitoring where configured.

No system is completely secure. You are responsible for configuring your institution carefully, reviewing privileged users, keeping credentials private, promptly removing access for departed users, monitoring account activity, and reporting suspected incidents.

We may review audit logs, security events, billing events, usage records, support records, and system logs to investigate abuse, enforce these Terms, comply with law, maintain service integrity, or support affected institutions. Security incident notices are governed by our Privacy Policy, Security Policy, applicable law, and any signed agreement.

13. Intellectual Property

13.1 Braille Link Materials

The Service, software, interfaces, code, workflows, documentation, trademarks, logos, templates, control planes, designs, databases, and related materials are owned by Avora Technologies Limited, its licensors, or its suppliers. Except for the limited right to use the Service under these Terms, no rights are transferred to you.

13.2 Limited Licence

Subject to these Terms and payment of applicable fees, we grant you a limited, revocable, non-exclusive, non-transferable, non-sublicensable licence to access and use the Service for your authorised educational, accessibility, administrative, research, or internal business purposes.

13.3 Restrictions

You must not copy, sell, lease, host, white-label, sublicense, modify, decompile, disassemble, reverse engineer, create derivative works from, remove notices from, or build a competing service using protected elements of the Service except where applicable law expressly permits such activity despite this restriction.

14. Feedback

If you send suggestions, comments, bug reports, accessibility feedback, ideas, or improvement requests, you grant us a perpetual, worldwide, royalty-free right to use that feedback to improve, commercialise, document, and support the Service without owing compensation, attribution, or confidentiality unless we separately agree in writing.

15. Suspension, Termination, and Deletion

We may suspend, restrict, or terminate access if we reasonably believe that: you violated these Terms; payment is overdue; your account creates security, legal, or operational risk; an institution requests removal; a role or tenant assignment was unauthorised; continued access may harm learners, users, Braille Link, or a third party; or law, court order, regulator request, or payment-gateway requirement requires action.

You may stop using the Service at any time. Account deletion is subject to identity verification, ownership transfer, billing records, legal holds, audit needs, backup windows, institutional record duties, learner submissions, fraud prevention, unresolved disputes, and retention policies. Deleting a user account may not delete institution-controlled records or records that must be retained by law or for legitimate security, billing, dispute, audit, or compliance purposes.

Provisions that by their nature should survive termination will survive, including payment obligations, privacy and data-protection provisions, intellectual property provisions, disclaimers, liability limits, indemnities, dispute provisions, audit rights, and retention rights.

16. Disclaimers

THE SERVICE AND ALL OUTPUTS ARE PROVIDED "AS IS" AND "AS AVAILABLE." TO THE FULLEST EXTENT PERMITTED BY LAW, BRAILLE LINK DISCLAIMS ALL EXPRESS, IMPLIED, STATUTORY, AND OTHER WARRANTIES, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, ACCURACY, QUIET ENJOYMENT, AVAILABILITY, AND ERROR-FREE OPERATION.

We do not warrant that the Service will meet every accessibility requirement, institutional requirement, education-record requirement, procurement requirement, grant requirement, or user expectation. We do not warrant that translations, OCR results, document transcription, generated Reader narration, browser-extension behavior on third-party sites, exports, speech previews, tables, analytics, billing status, audit logs, or security signals will be complete, uninterrupted, secure, or error-free.

No advice or information, whether oral or written, creates a warranty unless expressly stated in a signed written agreement by an authorised Braille Link representative.

17. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, BRAILLE LINK AND ITS DIRECTORS, OFFICERS, EMPLOYEES, CONTRACTORS, AFFILIATES, LICENSORS, AND SUPPLIERS WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, PUNITIVE, OR ENHANCED DAMAGES; LOSS OF PROFITS, REVENUE, GOODWILL, DATA, CONTENT, BUSINESS, OPPORTUNITY, OR EXPECTED SAVINGS; SERVICE INTERRUPTION; PROCUREMENT LOSS; EDUCATIONAL DELAY; OR COST OF SUBSTITUTE SERVICES, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF: (A) THE FEES PAID BY YOU OR YOUR INSTITUTION TO BRAILLE LINK FOR THE SERVICE IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO LIABILITY; OR (B) USD 100.

The above limits do not exclude liability that cannot lawfully be excluded, such as liability for fraud, wilful misconduct, or any other liability that applicable law says cannot be limited.

18. Indemnity

To the maximum extent permitted by law, you will defend, indemnify, and hold harmless Braille Link and its directors, officers, employees, contractors, affiliates, licensors, and suppliers from claims, losses, liabilities, damages, penalties, costs, and expenses, including reasonable legal fees, arising from:

• Your Content or your use of outputs.
• Your violation of these Terms, the Acceptable Use Policy, or applicable law.
• Your unauthorised use, invitation, role assignment, tenant change, billing action, or learner-data processing.
• Your failure to obtain required notices, consents, approvals, procurement authorisations, or lawful bases.
• Your misuse of third-party services, payment gateways, open-source components, or another person's rights.

We may control the defence of any claim for which indemnity is sought. You must cooperate and must not settle a claim in a way that imposes obligations on Braille Link without our written consent.

19. Governing Law and Disputes

These Terms are governed by the laws of the Republic of Uganda, without regard to conflict-of-law rules. Subject to any mandatory law that gives you another forum, the courts of Uganda will have exclusive jurisdiction over disputes arising from or relating to these Terms or the Service.

Before filing a formal claim, each party will use reasonable efforts to resolve the dispute in good faith by sending a written notice describing the issue and allowing 30 days for discussion, unless urgent injunctive relief, account protection, data protection, safety, payment, or legal compliance requires faster action.

20. Changes

We may update these Terms to reflect changes in law, security requirements, product features, billing, institutional workflows, provider requirements, or business operations. We will post the updated Terms with a new effective date and version. For material changes, we will use reasonable efforts to notify affected users by email, in-product notice, or another appropriate method where practical.

Your continued use of the Service after the updated Terms take effect means you accept the updated Terms. If you do not accept them, you must stop using the Service and cancel your subscription where applicable.
