Terms of Service

Last Updated: 8 May 2026

These Terms of Service ("Terms") govern your access to and use of the Graylin platform, including our website, applications, APIs, and related services ("Graylin", "the Service"). By creating an account or using the Service, you acknowledge that you have read, understood, and agree to these Terms.

1. Definitions

• "User" means any individual or entity who accesses or uses the Service.
• "We", "Us", "Our", "Company" refers to the operator of Graylin.
• "Content" includes text, code, data, AI-generated responses, files, or other materials processed through the Service.
• "Personal Data" means any information relating to an identifiable individual as defined under applicable privacy laws.
• "Tenant" means an isolated workspace provisioned for a User within the Service.

2. Eligibility

You must be at least 18 years old or the age of majority in your jurisdiction to use the Service. If you are using the Service on behalf of an organization, you represent that you have authority to bind that organization to these Terms.

3. Service Description

Graylin provides a personal AI assistant platform with per-tenant isolation. Each tenant receives a dedicated, secure environment for interacting with AI capabilities. The Service may include:

• AI-powered conversational assistants
• Data processing and analysis tools
• Integration capabilities with third-party services
• Storage for conversations and user data

4. AI-Generated Content Disclaimer

Graylin uses artificial intelligence and machine learning models to provide responses and assistance. You acknowledge and agree that:

• AI-generated content may be inaccurate, incomplete, or inappropriate for your specific use case.
• AI responses do not constitute professional advice (legal, medical, financial, or otherwise).
• You are responsible for reviewing and verifying any AI-generated content before relying on it.
• We do not guarantee the accuracy, reliability, or suitability of AI outputs.

5. User Accounts & Security

• You must provide accurate information during registration.
• You are responsible for maintaining the confidentiality of your account credentials and API keys.
• You agree not to share your account or impersonate any person or entity.
• You must notify us immediately of any unauthorized access to your account.

6. Acceptable Use

You agree NOT to use the Service to:

• Violate any applicable laws or regulations.
• Generate harmful, illegal, or unethical content.
• Attempt to circumvent security measures or access other users' data.
• Overload, disrupt, or reverse engineer the Service.
• Use the Service to develop competing AI products using our outputs.
• Process data that you do not have the right to process.

7. Data Ownership & Privacy

You retain ownership of all data you input into the Service ("User Data"). You grant Graylin a limited license to:

• Store and process your User Data to provide the Service.
• Create anonymized, aggregated analytics to improve the Service.

Your privacy is governed by our Privacy Policy, which forms part of these Terms. We do not sell your personal data.

8. Tenant Isolation & Security

Each tenant operates in an isolated environment. We implement security measures including:

• Per-tenant encryption keys
• Isolated compute environments
• Access controls and audit logging

However, no system is completely secure. You acknowledge that you use the Service at your own risk.

9. Third-Party Integrations

The Service may integrate with third-party AI providers, cloud services, and other platforms. We are not responsible for the terms, actions, or omissions of third parties. Your use of third-party integrations is subject to their respective terms and policies.

10. Intellectual Property

All proprietary rights in the Service—including branding, software, algorithms, and documentation—belong to the Company or its licensors. You may not copy, modify, or distribute our intellectual property without permission.

11. Payments, Subscriptions, and Credits

11.1 Subscriptions

Access to certain features of the Service requires a paid subscription. Subscription tiers, pricing, billing cycles, and included features are presented at the point of purchase and in your account dashboard. Subscriptions are available on monthly or annual billing cycles.

• Monthly subscriptions are billed in advance for one month and renew automatically each month unless cancelled before the next renewal date.
• Annual subscriptions are billed in advance for the full twelve-month term and renew automatically at the end of each term unless cancelled before renewal. The annual fee is recognised over the term as the Service is delivered; the unrecognised portion is held as deferred revenue and represents our outstanding obligation to provide the Service for the remainder of the paid term.
• We may revise pricing on at least 30 days' notice via the Service or the email address on your account. New pricing applies from your next renewal date.

11.2 Credits — Nature and Use

Certain features of the Service — including AI inference, document extraction, web search, and paid third-party integrations ("Paid Connectors") — are metered in Credits. Credits represent a prepaid right to consume metered features at the consumption rates published in the Service. Credits are not legal tender, currency, or any form of property right; they have no equivalent value in fiat currency and are not redeemable, refundable, or exchangeable for any sum of money or monetary value, except where required by applicable law.

11.3 Bundled Credits

Each paid subscription tier includes a monthly allowance of Credits ("Bundled Credits"). Bundled Credits:

• Are issued at the start of each monthly billing cycle.
• Are consumed first, before any Top-up Credits, when you use metered features.
• Do not roll over. Any Bundled Credits unused at the end of a billing cycle expire and are forfeited.
• Are forfeited on cancellation, suspension, or termination of the underlying subscription.

11.4 Top-up Credits

You may purchase additional Credits ("Top-up Credits") via the Service at the prices published at the time of purchase. Top-up Credits:

• Are consumed after Bundled Credits have been exhausted in the current billing cycle.
• Carry an expiry date of twelve (12) months from the date of purchase. Unused Top-up Credits expire at the end of that period and are forfeited.
• Cannot be transferred between accounts, tenants, or subscription tiers.
• Cannot be combined with other accounts or aggregated across separate billing relationships.

Cash received in respect of Top-up Credits is held as deferred revenue and recognised as Credits are consumed or expire. We do not extend the expiry date of issued Credits.

11.5 No Refunds

All sales of subscriptions and Credits are final and non-refundable, except where a refund is required by applicable law or as set out below.

Limited circumstances in which we will consider a refund or credit:

• Confirmed account compromise. If your account is accessed without authorisation and Credits are consumed, contact support@graylin.ai immediately. Where unauthorised use is confirmed, we will restore Credits or, at our discretion, refund the affected purchase.
• Material service failure attributable to us. If the Service is materially unavailable for a sustained period attributable to us and not to your environment, third-party providers, or factors outside our reasonable control, you may request a service credit or pro-rated subscription refund.
• Statutory rights. Where applicable consumer-protection laws (for example the South African Consumer Protection Act, the EU Consumer Rights Directive, or equivalent regimes in your jurisdiction) grant you a non-waivable right to a refund or cooling-off period, those rights apply and prevail over this clause to the extent of any conflict.

11.6 App Store and Google Play Purchases

Subscriptions and Credits purchased via the Apple App Store or Google Play are billed by the respective platform. Refunds for those purchases are governed by Apple's or Google's billing terms and policies, not by Section 11.5. Refund requests for Apple-billed purchases must be submitted to Apple; refund requests for Google-billed purchases must be submitted to Google. We have no ability to issue refunds for purchases we did not collect.

11.7 Account Termination and Forfeiture of Credits

• Cancellation by you. You may cancel your subscription at any time. Your subscription remains active until the end of the current billing cycle, after which it will not renew. Bundled Credits are forfeited on cancellation. Top-up Credits remain usable until their twelve-month expiry, subject to your continued compliance with these Terms; thereafter they are forfeited.
• Termination by us for breach. Where we terminate your account for breach of these Terms (including the Acceptable Use clause), all unused Bundled Credits and Top-up Credits are forfeited and no refund is due, except where required by law.
• Termination by us without cause. If we terminate your account without cause, we will refund the unused portion of any prepaid subscription term on a pro-rata basis and credit you the cash value of any unconsumed Top-up Credits. Bundled Credits are not separately refundable; they are deemed consumed in consideration for access to the Service through the date of termination.

11.8 Failed Payments

If a renewal payment fails, we may retry the payment for up to seven (7) days. If payment is not received within that period, the Service may be suspended. Accounts suspended for non-payment may be terminated after thirty (30) days. Account data is retained for the period set out in our data retention policy and is not destroyed earlier solely because of payment failure.

11.9 Taxes and Currency

Prices are stated exclusive of applicable taxes (including VAT, sales tax, and similar indirect taxes) unless explicitly stated otherwise. Where a payment platform (Polar, Apple App Store, Google Play, or other merchant of record) collects and remits VAT or sales tax on our behalf in your jurisdiction, that platform handles the customer-facing tax computation. Graylin remains responsible for South African Value-Added Tax obligations on income that we receive directly. All amounts are stated in United States Dollars (USD) unless otherwise indicated; conversion to your local currency at point of purchase is handled by the merchant of record.

11.10 Statutory Exceptions

Nothing in this Section 11 limits, excludes, or modifies any non-waivable right or remedy you may have under the consumer-protection laws of your jurisdiction. Where there is a conflict between this Section and a non-waivable statutory right, the statutory right prevails to the extent of the conflict, but only to that extent.

12. Service Availability

We strive to maintain high availability but do not guarantee uninterrupted service. We may perform maintenance, updates, or experience outages. We will endeavor to provide notice of planned maintenance.

13. Termination

We may suspend or terminate your access if you violate these Terms or engage in harmful behavior. You may delete your account at any time. Upon termination, your data will be deleted in accordance with our data retention policies.

14. Limitation of Liability

To the fullest extent permitted by law, the Company shall not be liable for:

• Indirect, incidental, or consequential damages;
• Loss of data, profits, or business opportunities;
• Damages arising from reliance on AI-generated content;
• Issues caused by third-party services or integrations.

15. Indemnification

You agree to indemnify and hold harmless the Company from any claims, liabilities, damages, or expenses arising from your use of the Service or your breach of these Terms.

16. Governing Law

These Terms are governed by the laws of the jurisdiction in which the Company is incorporated, unless otherwise required by consumer protection laws in your region.

17. Changes to Terms

We may revise these Terms at any time. Material changes will be communicated via email or through the Service. Continued use after changes constitutes acceptance.

18. Apple App Store Additional Terms

The following additional terms apply to your use of the Graylin iOS application obtained from the Apple App Store (the "Apple-Sourced Application") and supplement, and where in conflict supersede, the other provisions of these Terms with respect to that application.

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