How AEFINTYR LLC handles personal information

Effective date: 1 January 2026  |  Last updated: 1 January 2026

This Privacy Policy explains how AEFINTYR LLC collects, uses, stores and protects personal information when you visit the website at aefintyr.buzz, contact our bench, or engage our systems design services. It was prepared by the developer Aefintyr, who maintains this website, and it applies to every visitor and every client of the company. We have written it in plain language on purpose, because a policy that cannot be understood is not much of a protection. If any part of this document is unclear, please write to support@aefintyr.buzz and we will explain it directly.

1. Who We Are

AEFINTYR LLC is a computer integrated systems design practice registered in the United States. Our principal place of business is 2227 3rd Ave SW, Rochester - 55902-2307, United States (US). We design, integrate and document connected operations for commercial buildings, industrial floors, institutional campuses and critical rooms, and we operate a fusion splicing laboratory bench as the centre of our technical craft.

For the purposes of applicable data protection law, AEFINTYR LLC is the controller of the personal information described in this policy. That means the company decides why and how personal information is processed, and the company is accountable for doing so lawfully. Where we act on behalf of a client during a project and process data that belongs to that client operation, we act as a processor under the instruction of that client, and the client remains the controller of its own data.

You can reach the company at any time by email at support@aefintyr.buzz or by telephone at +17758541180. Postal correspondence should be addressed to AEFINTYR LLC, 2227 3rd Ave SW, Rochester - 55902-2307, United States (US).

2. Scope of This Policy

This policy covers the website located at aefintyr.buzz and every page published under that domain, including the homepage, the services page, the contact page and the legal pages. It also covers personal information you provide to us through email, telephone, a contact form, a proposal, a contract or any other direct communication with our bench.

This policy does not apply to third party websites that we may link to, nor to the internal systems of our clients, nor to data that a client collects and controls independently of our engagement. When we process client operational data during a project, that processing is governed by the agreement between AEFINTYR LLC and the client, together with any data processing addendum we have signed, rather than by this public policy.

If you are visiting this website from outside the United States, please be aware that our operations are based in the United States and that information you send to us will be handled there. We describe cross border handling in more detail later in this document.

3. Information We Collect

We keep collection to the minimum needed to answer your enquiry and to deliver our services. The categories of personal information we may collect are set out below.

Information you give us directly

  • Identity and contact details such as your name, company name, job title, email address, postal address and telephone number.
  • The content of any message you send us, including the project context, site details and any files you choose to attach.
  • Contract and billing details for clients, such as purchase order references, invoicing contacts and payment information handled by our finance provider.
  • Access and site information needed to deliver a project, such as building addresses, contact names for site access and the credentials you issue to our engineers for a controlled visit.

Information collected automatically

  • Technical information sent by your browser, such as the internet protocol address, the browser type and version, the operating system, the referring page and the pages you view on this site.
  • Server log information that records the time and date of a request, the page requested and the response status, kept for security and reliability purposes.

Information we do not wish to receive

We ask that you do not send us sensitive categories of personal information through this website. That includes health information, government identification numbers, financial account numbers, biometric data and information about children. Our work does not require it, and sharing it creates a risk for you that we would rather avoid.

4. How We Collect Information

Most of the information we hold reaches us because you chose to send it. When you complete the contact form on this website, your browser composes a message in your own email client and sends it to support@aefintyr.buzz. The website itself does not store the content of that form on a server. This is a deliberate design choice, and it means the copy of your message lives in your sent mail and in our inbox rather than in a database we operate.

We also collect information automatically through the ordinary operation of a web server. Our hosting platform records technical requests so that we can keep the site available and detect abuse. We collect information from clients during the ordinary course of an engagement, through meetings, surveys, drawings, email threads and formal documents.

In limited situations we may receive information about you from a third party. For example, a colleague may introduce you by email, a client may provide your details as a site contact, or a supplier may pass on the name of the person responsible for a delivery. When that happens we treat the information with the same care described in this policy.

5. Legal Bases for Processing

Where data protection law requires a legal basis for processing, we rely on the following grounds. We rely on your consent when you choose to send us an enquiry through the contact form, when you subscribe to any advisory notice we may offer, and when you ask us to add your name to a project mailing list. You may withdraw consent at any time by writing to support@aefintyr.buzz.

We rely on the performance of a contract when we process information needed to provide services you or your organisation have engaged, to issue invoices, to deliver project records and to support the systems we have designed. We rely on our legitimate interests when we respond to business enquiries, maintain the security and reliability of this website, keep records of our professional work, and protect the company against fraud or misuse. Where we rely on legitimate interests we weigh those interests carefully against your rights and expectations.

We rely on legal obligation when we must retain records for tax, accounting, dispute or regulatory purposes, and when we are required to respond to a lawful request from a competent authority. Finally, we rely on vital interests only in the rare emergency where it is necessary to protect life or safety.

6. How We Use Information

We use personal information for the following purposes, and we do not use it for anything incompatible with them.

  • To respond to your enquiry and to hold a meaningful conversation about your project.
  • To prepare proposals, surveys, designs, schedules and documentation for clients.
  • To deliver services, manage projects, arrange site access and coordinate with trades and suppliers.
  • To issue invoices, collect payment and maintain proper accounting records.
  • To keep the website secure, available and free from abuse.
  • To improve our services by reviewing how clients engage with us and where our process can be made stronger.
  • To comply with legal, tax and regulatory obligations, and to establish, exercise or defend legal claims.

We do not sell personal information. We do not rent it, trade it or exchange it for advertising. We do not use the content of client projects to train advertising profiles, and we do not send marketing messages to people who have not asked to hear from us.

7. Cookies and Similar Technologies

This website is designed to work without advertising cookies. We do not place tracking cookies for the purpose of building a profile of your browsing across other sites, and we do not operate third party advertising pixels.

Our hosting platform may set a small number of strictly necessary technical cookies or store equivalent values to keep a session stable, to balance traffic and to protect the site against abuse. These values do not identify you by name and are not used for marketing. If we ever introduce an optional analytics service in the future, we will update this policy, and where the law requires it we will ask for your consent before any optional cookie is set.

You can control or delete cookies through your browser settings. Blocking strictly necessary cookies may affect how parts of this site behave, but the core content of every page will remain readable. Guidance for cookie controls is available in the help section of your chosen browser.

8. When We Share Information

We share personal information only where it is necessary and only with parties who are bound to protect it. The situations in which sharing may occur are described below.

  • With service providers who support our operations, such as our hosting provider, our email provider, our accounting software and our professional advisers. Each provider receives only what it needs for its function.
  • With project partners such as contractors, suppliers and specialist engineers when a client engagement requires coordination. We share the minimum details needed for the task, and we do so in the context of a client project.
  • With professional advisers such as lawyers, auditors and insurers when we need advice or when a claim must be handled.
  • With authorities when the law requires it, when a court order compels it, or when it is necessary to protect the rights, safety or property of AEFINTYR LLC, our clients or the public.
  • With a successor organisation in the event of a merger, acquisition or sale of assets, in which case we will require the recipient to honour this policy.

We do not share personal information with advertisers, data brokers or any party whose purpose is to resell it. When we share information with a processor, we put a written agreement in place that limits the processor to our documented instructions.

9. Service Providers and Processors

A modern consultancy depends on a small set of infrastructure providers, and we choose ours with care. Our website is served by a hosting provider that keeps technical logs and protects the site edge. Our email is handled by a provider that stores messages and filters unwanted mail. Our documents and drawings live in a controlled workspace with access limited to the engineers who need them.

Each provider is selected partly on its security posture and its willingness to sign a data processing agreement. Those agreements require the provider to process personal information only on our instructions, to apply appropriate technical and organisational measures, to assist us in responding to individual rights requests, to notify us of a breach without undue delay, and to delete or return information when the engagement ends.

We review our provider list periodically. If a provider can no longer meet our standard, we replace it, and where the change affects how personal information is handled we update this policy. A current list of the categories of provider we use is available on request by writing to support@aefintyr.buzz.

10. How Long We Keep Information

We keep personal information only for as long as it serves the purpose for which it was collected, plus any additional period required by law. Retention is not indefinite, and we review our records on a regular cycle so that material which is no longer needed is removed.

Enquiries that do not become projects are normally kept for up to twenty four months so that we can pick up a conversation if you return to us. Project records for active clients are kept for the duration of the engagement and for the warranty and support period that follows. Financial and tax records are kept for the period required by applicable law, which in the United States is commonly seven years. Documentation that forms part of a delivered system, such as as built records, may be retained for the life of the system because it is a safety and maintenance asset for the client.

When a retention period ends we delete the information or, where deletion is not immediately possible because of backup cycles, we isolate it and delete it as soon as the cycle completes. If you would like to know the retention position for a specific category of information, contact us and we will explain it.

11. How We Protect Information

Security at AEFINTYR LLC follows the same principle we apply to systems design: measure the protection rather than assume it. We use encryption in transit for the website and for email where the receiving service supports it. Access to our document workspace requires individual accounts with multi factor authentication, and access is granted on the basis of the work a person is actually doing rather than on seniority.

We keep the number of systems holding personal information deliberately small. Staff and contractors are bound by confidentiality obligations, and they receive guidance on handling client information. We test our backups, we keep an inventory of where information lives, and we have a documented procedure for responding to a suspected incident.

No method of transmission or storage is completely secure, and we cannot promise absolute security. If we become aware of a breach that affects your personal information, we will notify you and the relevant authority as required by applicable law, and we will tell you what we know, what we are doing and what you should consider doing.

12. International Data Transfers

AEFINTYR LLC is based in the United States, and our core systems are hosted there. If you contact us from another country, your information will be transferred to and processed in the United States. We take steps to ensure that such transfers are lawful and that the information continues to receive an appropriate level of protection.

Where a transfer originates in a jurisdiction that restricts transfers to the United States, we rely on an approved transfer mechanism. Depending on the circumstances this may be a data processing agreement incorporating standard contractual clauses, an adequacy decision, or your explicit consent where consent is the appropriate basis. We assess the laws of the destination and apply supplementary measures where they are needed.

Because our practice is small and our provider set is deliberately limited, we can usually explain exactly where a given piece of information is stored. If you need that detail for your own compliance review, write to support@aefintyr.buzz and we will provide it.

13. Your Privacy Rights

Depending on where you live, you may have a set of rights over your personal information. AEFINTYR LLC honours these rights for everyone who contacts us, regardless of location, because a consistent standard is easier to keep than a patchwork.

Rights you may exercise

  • The right to know whether we hold personal information about you and to receive a copy of it.
  • The right to correct information that is inaccurate or incomplete.
  • The right to request deletion of information we no longer have a lawful reason to keep.
  • The right to restrict or object to certain processing, including processing based on legitimate interests.
  • The right to data portability, so that information you provided can be received in a structured and machine readable form.
  • The right to withdraw consent at any time where processing is based on consent.
  • The right not to receive discriminatory treatment for exercising any of these rights.

To exercise a right, email support@aefintyr.buzz with enough detail for us to identify you and to understand the request. We will acknowledge your request promptly and respond within the period required by applicable law, normally within thirty days. We may ask you to verify your identity before we act, and we will explain our reasoning if we are unable to fulfil a request. You also have the right to complain to your local supervisory authority, and we would rather hear from you first so that we can put matters right.

14. Privacy for Children

This website and our services are intended for businesses and professional clients. They are not directed at children, and we do not knowingly collect personal information from anyone under the age of sixteen. Our work concerns building systems and networks, not consumer products, and no part of this site is designed to appeal to young visitors.

If you believe that a child has provided personal information to us, please write to support@aefintyr.buzz. We will investigate, and if the information was collected without appropriate consent we will delete it as quickly as we reasonably can. If a client project ever involves an environment where children are present, such as a school campus, we design systems that minimise personal data, and we recommend privacy protective defaults as part of our systems architecture work.

15. Do Not Track and Signals

Some browsers offer a Do Not Track setting, and some jurisdictions require businesses to disclose how they respond to it. Because this website does not run behavioural advertising trackers and does not build cross site profiles, there is no tracking activity for a Do Not Track signal to switch off. We honour the spirit of the signal by keeping tracking to a minimum.

If a global privacy control or a similar opt out preference signal is received, we treat it as a request to refrain from any sale or sharing of personal information. We do not sell or share personal information in any case, so the signal aligns with our existing behaviour. We document our position here so that the policy remains accurate as browser privacy features evolve.

16. Third Party Links

Our pages may occasionally link to external resources such as a standards body, a technical reference or a supplier page. Once you follow such a link you have left our site, and the privacy practices of the destination are governed by that organisation rather than by AEFINTYR LLC.

We choose links with reasonable care, but we cannot control the content or the data practices of an external site, and we cannot accept responsibility for them. We encourage you to read the privacy notice of any site you visit, particularly before providing personal information. If you find a link on this site that leads somewhere harmful or misleading, please tell us so that we can review it.

17. Changes to This Policy

We review this Privacy Policy regularly and update it when our practices, our providers or the law change. When we make a material change, we will update the effective date at the top of this page and, where the change is significant and we hold your contact details for an active matter, we will tell you directly by email.

We keep prior versions available on request so that you can see what changed and when. Continued use of this website after an update indicates that you accept the revised policy, and we recommend that you check back occasionally. If you do not agree with a change, you are free to stop using the site and to ask us to delete the information we hold about you.

This policy does not create contractual rights beyond those provided by applicable law, and it does not limit any right that cannot be limited by law. Nothing in this policy obliges AEFINTYR LLC to retain information it would otherwise lawfully delete.
