Terms of service

Last Updated: September 10, 2026

These Terms of Sale and Use ("Terms") govern your access to and use of the websites, online storefronts, software, firmware, applications, hardware products, accessories, content, support services, and related services branded Paper_Tracker (collectively, the "Services").

These Terms form a binding agreement between you and PAPER TRACKER TECHNOLOGY LIMITED, operating under the Paper_Tracker brand ("Paper_Tracker", "we", "our", or "us"). By accessing or using the Services, creating an account, placing an order, clicking to accept, downloading software, activating a device, or otherwise using any part of the Services, you agree to be bound by these Terms, our Privacy Policy, our Return and Refund Policy, our Limited Warranty Policy, and any additional terms presented to you for specific products, software, beta features, or optional programs.

1. Eligibility and Accounts

  1. You represent and warrant that you have the legal capacity to enter into these Terms. If you use the Services on behalf of a company or other legal entity, you represent and warrant that you have authority to bind that entity.
  2. You must provide accurate, current, and complete account, order, shipping, and contact information and keep such information up to date.
  3. You are responsible for maintaining the confidentiality of your account credentials and for all activities that occur under your account. You must promptly notify us of any unauthorized access, misuse, or security incident involving your account.
  4. We may refuse, suspend, or terminate accounts or orders to the extent permitted by law where we reasonably believe there is fraud, abuse, sanction risk, export-control risk, payment risk, or a violation of these Terms.

2. Products, Availability, Compatibility, and Pricing

  1. Product descriptions, images, specifications, availability, compatibility information, estimated shipping dates, and pricing are provided for general information and may change from time to time.
  2. We make commercially reasonable efforts to describe our products accurately, but minor differences in appearance, packaging, software interface, or specifications may occur.
  3. Compatibility with third-party headsets, operating systems, drivers, platforms, games, engines, avatars, or software is not guaranteed on a permanent basis and may change due to updates, deprecations, policy changes, or third-party actions beyond our control.
  4. We reserve the right to correct errors, inaccuracies, or omissions in pricing, product descriptions, availability, shipping estimates, or promotional materials, and to update or cancel affected orders where permitted by law.

3. Orders, Payment, and Fulfillment

  1. Your order is an offer to purchase. We may accept, reject, limit, or cancel any order to the extent permitted by law, including in cases of suspected fraud, abuse, resale activity, pricing error, stock error, sanctions or export-compliance concerns, or payment verification issues.
  2. Pre-order purchase limits and order review

    To give more customers the opportunity to buy and experience Paper_Tracker at official prices, and to reduce reselling and stockpiling, purchase limits may apply to the second international early-bird pre-order batch.

    We reserve the right, to the extent permitted by applicable law, to manually review and cancel orders where there are multiple clearly duplicate orders to the same shipping address, unusual bulk purchases or similar patterns. These measures aim to allocate the limited pre-order availability for this batch fairly. Thank you for your understanding and cooperation.

  3. Prices displayed on the Services may not include taxes, duties, customs charges, import fees, currency conversion charges, or payment-processing charges unless expressly stated otherwise. You are responsible for such amounts where applicable.
  4. Orders shipped to the European Union use DDU / DAP delivery. Except for amounts expressly itemized and collected at checkout, the recipient is responsible for import VAT, customs duties and customs-clearance charges, and must cooperate with import clearance. See our Shipping Policy.
  5. You are responsible for providing a complete and deliverable shipping address and any information required for customs clearance, import processing, or local delivery.
  6. Risk of loss and title transfer at the time permitted by applicable law and specified in your order confirmation, shipping terms, or mandatory local law.

If we cancel an unfulfilled order because of purchase limits, stock availability or our order review, we will refund all amounts paid to us for the cancelled order, including shipping charges, without a processing fee. For a partial cancellation, we refund the cancelled items and any shipping charges attributable to them; the remaining order is unchanged. For these seller-initiated cancellations, we initiate the refund without undue delay and normally within 10 business days of our cancellation decision, subject to any earlier legal deadline.

4. Cancellations, Returns, and Digital Content

  1. As a voluntary store policy, and except where mandatory applicable consumer law provides otherwise, standard product orders may be cancelled within one (1) hour after the order is placed, provided the order has not entered fulfillment, manufacturing, cutting, calibration, packaging, or shipment.
  2. Customized, made-to-order, or clearly personalized products, including custom lenses and other products manufactured to your prescription, measurements, specifications, or individualized requirements ("Custom Products"), may only be changed or cancelled within one (1) hour after the order is placed, unless a longer period is required by mandatory law. Except as required by law, Custom Products are non-returnable for change-of-mind reasons once production begins.
  3. Digital content, software licences, firmware, subscriptions, downloadable files and feature unlocks may be supplied or activated at your request. Any limitation or loss of a statutory cooling-off or withdrawal right applies only when the conditions required by applicable law have been met. Where the law requires prior express consent to immediate supply and acknowledgement of the resulting loss of that right, we will obtain that consent and acknowledgement separately.
  4. Nothing in these Terms limits any non-waivable statutory return, withdrawal, rejection, repair, replacement, or refund rights that may apply to you under mandatory consumer law.
  5. Additional conditions for returns, exchanges, damaged goods, non-delivery claims, and refund processing are set out in our Return and Refund Policy.

Where EU consumer withdrawal rules apply, ordinary goods normally carry a 14-day withdrawal period after receipt, including ordinary pre-order goods. Custom prescription products and digital content may have legal exceptions. Statutory withdrawals are not subject to our 6% processing fee. The Return and Refund Policy explains the procedure, delivery costs and refund deadlines.

5. Limited Commercial Warranty

  1. Subject to the exclusions and procedures in our Limited Warranty Policy, we provide a one (1) year limited commercial warranty from the date of delivery that the hardware product will substantially conform to its published documentation under normal and intended use.
  2. This limited commercial warranty is in addition to, and does not replace, any non-excludable statutory rights or legal guarantees that apply under mandatory law.
  3. The limited commercial warranty does not cover, to the extent permitted by law, normal wear and tear, cosmetic damage, consumables, misuse, abuse, accidents, drops, liquid damage, improper installation, improper calibration, unauthorized repairs or modifications, use with unsupported hardware or software, failure to follow documentation, use outside intended operating conditions, prescription data supplied incorrectly by the customer, or issues caused by third-party platforms, software, or services.

This one-year commercial warranty is additional to statutory rights. Where EU consumer guarantee rules apply, goods normally have a minimum two-year legal guarantee from delivery, and some countries provide longer protection. Expiry of our commercial warranty does not end those rights.

6. Software License

  1. Subject to these Terms, Paper_Tracker grants you a limited, revocable, non-exclusive, non-transferable, non-sublicensable license to install and use the software and firmware provided with the product solely for your personal or internal business use with authorized Paper_Tracker products.
  2. Except to the extent such restriction is prohibited by applicable law, you may not, and may not permit any third party to:
    • copy, modify, adapt, translate, distribute, sell, rent, lease, sublicense, host, or commercially exploit the software except as expressly authorized;
    • reverse engineer, decompile, disassemble, decode, or attempt to derive source code, model weights, algorithms, file formats, or non-public interfaces;
    • circumvent or interfere with security, licensing, region-locking, anti-abuse, telemetry, or access-control mechanisms;
    • use the Services to build a competing product, train a competing system from protected software components, or perform unauthorized scraping, extraction, or automated access; or
    • remove or alter proprietary notices.
  3. We may provide updates, patches, firmware changes, compatibility fixes, or security improvements. Some updates may be required for continued functionality, compliance, or support.

7. Acceptable Use; No High-Risk, Medical, or Identification Use

  1. You may not use the Products or Services for any unlawful, infringing, deceptive, harassing, harmful, security-testing, surveillance, or unauthorized data-collection purpose.
  2. Unless we expressly state otherwise in writing, the Products and Services are not designed, marketed, or certified for:
    • medical diagnosis, treatment, rehabilitation, or clinical decision-making;
    • safety-critical systems, emergency response, aviation, driving, industrial control, life support, or similar high-risk uses; or
    • identity verification, access control, law enforcement, public surveillance, or automated decisions producing legal or similarly significant effects on individuals.
  3. You are solely responsible for ensuring that your use of the Products and Services complies with all applicable laws, platform rules, and third-party rights.

8. Image Data; Local Processing by Default

  1. In the ordinary default use of the Products and Services, images of the face and eyes ("Image Data") are processed locally on your device.
  2. Unless you separately and explicitly opt in to an optional Data Contribution Program, or unless you knowingly submit support materials containing such data, we do not upload Image Data to our servers, we do not store Image Data on our servers, and we do not perform server-side analysis of Image Data.
  3. Local on-device processing of Image Data may be necessary for core product functionality, such as tracking, calibration, animation output, gaze estimation, blinking, or expression mapping.

9. Optional Data Contribution Program

  1. We may from time to time offer an optional Data Contribution Program for dataset construction, model training, testing, evaluation, debugging, robustness analysis, fairness analysis, product improvement, and related research and development purposes.
  2. Participation in the Data Contribution Program is entirely voluntary and requires a separate, explicit, and clearly presented consent flow. Acceptance of these Terms alone does not enroll you in that program.
  3. If you do not join the Data Contribution Program, your refusal will not disable the core local tracking functionality of the product, except where a particular feature expressly depends on cloud processing and is separately identified as such.
  4. If you choose to join the Data Contribution Program, the separate consent notice will describe the categories of data involved, the purposes of processing, the retention approach, the withdrawal method, and any region-specific restrictions.
  5. You may withdraw consent through the options in the consent notice or by contacting support@papertracker.top. We stop new collection and other processing based solely on that consent. Where identifiable contributed data is no longer lawfully needed, we delete it or irreversibly anonymise it; any legally required retention is limited to the relevant purpose and period. Withdrawal does not affect processing that was lawful before it. Material that is genuinely irreversibly anonymous is treated separately from identifiable personal data. Use in a model, evaluation or security record does not by itself make information anonymous or remove your rights. We assess requests concerning those materials according to their actual identifiability and applicable law.
  6. The Data Contribution Program may be unavailable, restricted, or discontinued in certain countries, states, provinces, territories, or for certain users, devices, age groups, software versions, or business reasons.

10. Privacy, Support Materials, and Feedback

  1. Our processing of personal information is described in our Privacy Policy.
  2. If you voluntarily send us logs, recordings, screenshots, videos, bug reports, diagnostic packages, or other support materials, you represent and warrant that you have the right to provide such materials and that doing so does not violate any law or third-party rights.
  3. We may use support materials for troubleshooting, support, product quality, reliability, security, abuse prevention, and warranty evaluation.
  4. If you send us suggestions, ideas, feedback, improvement requests, bug reports, test results, or other non-confidential submissions regarding the Services ("Feedback"), you grant us a worldwide, perpetual, irrevocable, non-exclusive, royalty-free license to use, reproduce, modify, publish, distribute, and otherwise exploit that Feedback for product, service, and business purposes without compensation to you. This section does not override any separate explicit consent terms applicable to biometric or other regulated data.

11. Intellectual Property

  1. The Products and Services, including software, firmware, models, algorithms, documentation, interfaces, trade names, logos, graphics, product designs, and other materials, are owned by us or our licensors and are protected by applicable intellectual-property laws.
  2. Except for the limited license expressly granted in these Terms, no right, title, or interest in or to any intellectual property is transferred to you.

12. Third-Party Services and Platforms

The Services may interoperate with or link to third-party platforms, storefronts, payment processors, shipping providers, app stores, headsets, operating systems, analytics tools, or other services. We do not control third-party services and are not responsible for their acts, omissions, availability, policies, or terms. Your use of third-party services is governed by the applicable third-party terms and policies.

13. Disclaimers

Products and services remain subject to our published specifications, express promises, the Limited Warranty Policy and applicable law. General information about third-party services or future compatibility is not a guarantee that those third parties will remain unchanged.

Any exclusion of an additional implied warranty applies only where legally permitted. It does not exclude statutory quality, fitness or conformity rights, or our responsibility for the performance we have agreed to provide.

Limited Warranty Policy

14. Responsibility for Loss

We are responsible for losses caused by our breach or other acts or omissions to the extent required by applicable law. Liability is assessed according to the cause of the loss, the legally applicable rules on causation and foreseeability, and each party’s responsibility. These Terms do not impose a fixed monetary cap or a rolling payment-period cap.

Nothing in these Terms limits statutory refunds, repair, replacement or other mandatory remedies, or liability that cannot lawfully be excluded or limited, including liability for fraud, death or personal injury caused by our negligence, and mandatory product liability.

15. Responsibility for Third-Party Claims

To the extent permitted by law, if a third party brings a claim caused by your intentional or negligent misuse, infringement of third-party rights or unauthorised submission of content, you are responsible only for reasonable, documented losses attributable to your conduct. This does not include losses caused by us or our partners, impose an unlimited obligation to defend us, or restrict your statutory rights. We will inform you of a relevant claim and take reasonable steps to limit loss.

16. Suspension and Termination

We may suspend or terminate your access to all or part of the Services if we reasonably believe you have violated these Terms, created legal or security risk, engaged in fraud or abuse, or where suspension is required for legal, security, or operational reasons.

17. Governing Law and Disputes

Hong Kong law governs these Terms, subject to any mandatory consumer protections applicable to your purchase in your country of residence.

Hong Kong courts may hear disputes, but this does not prevent you from bringing a claim before any court available to you under mandatory consumer law, including a competent court in your place of residence. We will not use this clause to restrict that right.

18. Changes to These Terms

We may update these Terms for future use of the Services and future orders, stating the effective date and giving any notice required by law.

A later change does not retrospectively reduce the price, refund, delivery or warranty rights attached to an order already placed. Changes affecting an existing agreement require any consent or other legal basis required by applicable law; continued browsing alone is not consent to such changes.
