AffixIO Hub Payment Terms and End User Licence Agreement

1. Acceptance and binding effect

1.1 This AffixIO Hub Payment Terms and End User Licence Agreement (the Agreement) is a legally binding contract between you and AffixIO (also referred to as we, us, or our) governing your access to and use of AffixIO Hub (Hub), subscription billing through Hub, licence keys issued via Hub, the AffixIO software development kit and related self-hosted components (collectively, the SDK), and any associated application programming interfaces, documentation, and support channels we make available (together, the Services).

1.2 You accept this Agreement by any of the following: (a) ticking the acceptance box during Hub onboarding or checkout; (b) clicking a button or link indicating acceptance; (c) subscribing to a paid plan; (d) downloading, installing, or using the SDK with a licence key we issued; or (e) continuing to use the Services after we publish an updated version and notify you as described in Section 16.

1.3 If you accept on behalf of a company or other legal entity, you represent that you have authority to bind that entity. In that case, you means that entity and its authorised users.

1.4 If you do not agree to this Agreement, you must not register for Hub, subscribe, or use the SDK under an AffixIO licence key.

2. Definitions

Account means your registered Hub user profile and associated credentials.

Customer, you, or your means the individual or entity that accepts this Agreement.

Licence Key means a cryptographic or hashed credential (including keys prefixed aio_live_ or similar) issued through Hub that authorises SDK use subject to plan limits.

Plan means a subscription tier (such as Developer, Growth, Business, or Enterprise) with defined proof quotas, features, and fees as shown on Hub or affix-io.com/pricing.

Proof means a unit of cryptographic proof generation, verification, or related SDK operation counted against your Plan quota as reported by the SDK or our telemetry endpoints.

Stripe means Stripe, Inc. or its affiliates, which process card payments on our behalf where enabled.

Subscription means a recurring paid Plan linked to your Account through Stripe or manual Enterprise invoicing.

3. Description of Services

3.1 Hub is a control plane for managing licence keys, viewing usage statistics, configuring webhooks, exporting audit data, and administering billing. Hub does not itself process your end-user transactions unless you explicitly integrate with our hosted API for that purpose.

3.2 The SDK is designed for self-hosted deployment on infrastructure you control. You are solely responsible for installation, configuration, network security, key management, backups, scaling, and compliance of your deployment environment.

3.3 We may modify, suspend, or discontinue any part of the Services at any time, with or without notice, including features, plan limits, pricing for new subscriptions, and supported platforms. We have no obligation to maintain backward compatibility except where expressly stated in a separate written Enterprise agreement.

3.4 Beta, preview, or experimental features may be offered without service level commitments and may be withdrawn at any time.

4. Licence grant and restrictions

4.1 Subject to your compliance with this Agreement and payment of applicable fees, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable licence to install and use the SDK on systems you own or control, solely for your internal business purposes and within the limits of your Plan.

4.2 You may not: (a) sublicense, resell, or distribute the SDK or Licence Keys except as expressly permitted in writing; (b) reverse engineer, decompile, or attempt to derive source code except where such restriction is prohibited by applicable law; (c) remove or alter proprietary notices; (d) use the Services to build a competing product or service; (e) exceed Plan quotas except through permitted overage billing; (f) share Licence Keys across unrelated legal entities; (g) use the Services in violation of applicable law; or (h) probe, scan, or test vulnerabilities of our systems without prior written consent.

4.3 Licence Keys remain our property. Issuance of a key does not transfer ownership of any AffixIO intellectual property.

4.4 We may revoke or rotate Licence Keys immediately upon suspension, termination, non-payment, suspected fraud, or security incident.

5. Fees, billing, and taxes

5.1 Subscription fees are charged in advance for each billing period shown at checkout or in your Enterprise order form. Fees are quoted in British pounds unless otherwise stated.

5.2 You authorise us and Stripe to charge your designated payment method for recurring Subscription fees, applicable overage charges, taxes, and any other amounts due under this Agreement.

5.3 You are responsible for all taxes, duties, and government assessments associated with your purchase, excluding taxes based on our net income.

5.4 If a payment fails, is charged back, or is reversed, we may retry collection, suspend your Account, revoke Licence Keys, and terminate your Subscription without further notice.

5.5 Except where required by applicable consumer law, all fees are non-refundable. Downgrades take effect at the next billing cycle unless we agree otherwise in writing.

5.6 Enterprise Plans may be invoiced manually. Enterprise payment terms are as stated in the applicable order form or statement of work.

5.7 We may change prices for renewals or new subscriptions by posting updated pricing on Hub or our website. Continued use after the effective date of a price change constitutes acceptance for renewal periods.

6. Proof quotas and overage

6.1 Each Plan includes a monthly proof quota. Usage is measured by reports from the SDK and associated telemetry. You are responsible for monitoring usage in Hub.

6.2 If you exceed your included quota, overage fees apply on a tiered basis. Rates start at £0.010 per proof and step down to £0.005 as volume grows within the billing period. Current bands and your marginal rate are shown in Hub billing and stats.

6.3 New Hub accounts receive 100 free SDK proofs and a trial licence key for 30 days after email verification. Trial proofs do not roll over, cannot be extended, and do not bill overage. When the trial is used up or expires, the licence key is revoked until you subscribe on a paid plan.

6.4 Overage on paid plans may be billed through Stripe metered billing or invoicing. We may throttle, suspend, or revoke access if overage charges remain unpaid.

6.5 Enterprise Plans marked as unlimited are subject to fair use. We may contact you or adjust terms if usage is materially inconsistent with normal enterprise deployment patterns.

7. Suspension, revocation, and account cancellation

7.1 We may suspend, restrict, or terminate your Account, Subscription, or Licence Keys immediately and without liability if: (a) payment is overdue or a chargeback occurs; (b) you breach this Agreement; (c) we reasonably suspect fraud, abuse, or unauthorised access; (d) your use poses a security risk to us or others; (e) we are required to do so by law, regulation, court order, or request from a regulator, law enforcement agency, or other competent authority; or (f) we discontinue the Services or your Plan.

7.2 Upon suspension or termination for non-payment or breach, you remain liable for all accrued fees. We are not obliged to refund prepaid amounts.

7.3 You may cancel a Subscription through the Stripe customer portal where available, or by contacting us. Cancellation stops future renewals but does not entitle you to a refund for the current period unless required by law.

7.4 We may delete Account data after a reasonable period following termination, subject to legal retention obligations.

8. Technology disclaimer and your responsibilities

Important

8.1 AffixIO provides cryptographic proof infrastructure and related tooling. We do not guarantee that any proof, verification outcome, or access decision produced by the SDK or API will be legally sufficient, regulatorily compliant, or suitable for your specific use case in any jurisdiction.

8.2 You alone decide whether and how to rely on proofs in production workflows, including identity, eligibility, payments, access control, and record keeping. You are responsible for legal review, DPIAs, sector rules (such as financial services, healthcare, or employment law), and integration with your own policies.

8.3 The SDK runs on your hardware or cloud tenancy. We do not control and are not responsible for your operating systems, networks, databases, HSMs, key ceremonies, employee access, third-party libraries, or misconfiguration.

8.4 We do not warrant uninterrupted operation, error-free code, compatibility with future operating systems, or protection against all security threats. You must maintain patches, monitoring, and incident response for your deployment.

8.5 Any documentation, examples, or sample circuits are provided for illustration only and do not constitute legal, security, or professional advice.

10.2 OUR TOTAL AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE SERVICES SHALL NOT EXCEED THE GREATER OF: (A) THE AMOUNTS YOU PAID TO US FOR THE SERVICES IN THE TWELVE (12) MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM; OR (B) ONE HUNDRED BRITISH POUNDS (£100).

10.3 Nothing in this Agreement excludes or limits liability that cannot be excluded or limited under applicable law, including liability for death or personal injury caused by negligence, or fraud.

11.2 We will notify you of any claim subject to indemnification and cooperate reasonably. We may assume exclusive defence and control at your expense if you fail to defend promptly.

12. Law enforcement and regulatory requests

12.1 We may disclose Account information, usage records, billing data, and related metadata when we believe in good faith that disclosure is required by law, regulation, legal process, or governmental request.

12.2 We may suspend or revoke access immediately when we receive a credible request from law enforcement, a regulator, a court, or a payment network, without obligation to contest the request on your behalf.

12.3 You are responsible for lawful basis to process personal data in your deployments. We act as an independent controller or processor only to the extent described in our privacy materials.

13. Data, telemetry, and security

13.1 Hub may store Account profile data, billing metadata, usage statistics, webhook configurations, and audit exports you generate.

13.2 The SDK may transmit heartbeat, quota consumption, and licence validation signals to our API. You consent to such telemetry as a condition of using Licence Keys.

13.3 You must not submit special category personal data or secrets to Hub fields not designed for that purpose. You are responsible for classifying and protecting data in your environment.

13.4 We implement reasonable administrative and technical measures but do not guarantee absolute security. You must notify us promptly at hello@affix-io.com if you suspect compromise of your Account or Licence Keys.
