Legal — Terms, Privacy, Data Deletion

Terms & Conditions

These terms apply when you visit khz.blue, use any demo on it, or buy or use services from KHz. Please read them carefully. By using the website or our services you agree to them. If you do not agree, please do not use the website or services.

1. Who we are

The website and services are provided by KHz (“KHz”, “we”, “us”, “our”), an IT BPO and technology company. “You” means the person using the website, or the organisation that person represents. You can reach us at info@khz.blue or +92 335 3085099.

2. Using the website

You may use the website to learn about KHz and our products and to contact us. You must use it lawfully. You must not:

use the website for anything unlawful, fraudulent or harmful, or to harm or exploit children;
pretend to be someone else, including KHz or our staff;
try to break into, scan, overload or disrupt the website, our demos or the systems behind them, including by denial-of-service attacks;
upload or send viruses, malware or other harmful code;
copy, scrape or harvest content or data from the website with bots or other automated tools without our written permission;
send spam, unsolicited promotions or misleading information through any form, chat or demo.

You must be at least 18 years old to use our services.

3. Live demos

Demos such as the KHz Relay call demo and the chat widget are free and for evaluation only.

Only enter a phone number that belongs to you, or that you have permission to use.
Demo calls and chats may be answered by automated systems, including AI voice assistants.
We may limit the number of demo calls per number or visitor, restrict demos to certain countries, and stop or change any demo at any time without notice.
Demos may be unavailable, slow or interrupted. They do not show the performance or service levels of a paid deployment.

4. Quotes, orders and agreements

Product descriptions on this website are general information, not an offer. KHz products and services are supplied under a written quotation, order form or agreement (for example a licence, subscription or services agreement). If anything on this website conflicts with that agreement, the agreement applies. We may decline or cancel an order, for example if a product is unavailable, a price or description was wrong, or we suspect fraud or unlawful use.

5. Fees, renewals and refunds

Fees. Fees, payment terms and billing periods are set out in your quotation or agreement. Unless it says otherwise, subscriptions are billed in advance, monthly or yearly, and prices do not include taxes.
Renewals. Subscriptions renew automatically for the same period unless you or we cancel before the end of the current period, as your agreement describes.
Price changes. We will give you at least 30 days’ notice before a fee change. It takes effect from your next billing period, so you can cancel before it applies.
Late payment. If an invoice is not paid on time, we may suspend the service after giving you written notice.
Refunds. Fees already paid are not refundable, except where your agreement or the law says otherwise.

We do not store payment card details. Any card payments are handled by payment providers that follow industry security standards (PCI DSS).

6. Free trials and pilots

We may offer free trials or pilot deployments. We may change or end a trial at any time. Unless you move to a paid plan, data from a trial may be deleted 30 days after the trial ends.

7. Accounts and access

If you get an account for any KHz product or portal, keep your details accurate and your password and one-time codes private. You are responsible for everything done under your account. Tell us straight away if you think your account has been misused. We will never ask you for your password or one-time codes.

8. Your content and data

You own the content and data you or your users put into our services, such as call recordings, messages, contacts and files. You confirm you have the right to use it, including any consent the law requires. You allow KHz to store, process and display it only as needed to provide, secure and support the services for you. We do not monitor your content, but we may remove content that is unlawful or breaks these terms.

9. Third-party services and channels

Our services can connect to services run by others, such as telecom carriers, WhatsApp, Facebook, Instagram, email providers and AI model providers. Your use of those services is also governed by their own terms and privacy policies. We are not responsible for their availability, changes or actions.

10. Intellectual property

KHz and its licensors own the website, our software and their content, except content that belongs to you. This includes the KHz name and logo and the product names KHz Resonance, KHz Current, KHz Pulse, KHz Relay, KHz Echo AI, KHz Sonar AI, KHz Prism CRM, KHz Wavefront and KHz Blueprint. Nothing in these terms gives you the right to use them, except as your agreement allows. You may share links to our pages.

11. Feedback

If you send us ideas, suggestions or bug reports, we may use them freely to improve our products, without any obligation to you. Please do not include confidential information in feedback.

12. Copyright complaints

If you believe content on our website or services infringes your copyright, email info@khz.blue with the subject “Copyright complaint”. Include:

your contact details;
a description of the work;
where the infringing material is (for example its web address);
a statement that you believe in good faith the use is not authorised;
a statement that your notice is accurate and that you are the owner or authorised to act for them.

False or bad-faith claims may make you liable for the costs they cause.

13. Confidentiality

Each side will keep the other’s non-public business, technical and pricing information confidential. Each side will use it only for our work together, unless the law requires disclosure.

14. No warranties

The website and demos are provided “as is” and “as available”, without warranties of any kind. We do not promise that they will be uninterrupted, error-free or fit for a particular purpose. Warranties for paid services are only those written in your agreement. Nothing here removes rights that the law does not allow to be removed.

15. Limitation of liability

To the fullest extent allowed by law:

KHz is not liable for any indirect, incidental, special or consequential loss, or for loss of profit, revenue, data or business;
for paid services, KHz’s total liability is limited to the fees you paid us for the affected service in the 12 months before the claim;
for the free website and demos, KHz has no liability beyond what the law requires.

16. Indemnity

You agree to cover KHz for claims, losses and reasonable legal costs that arise because you broke these terms or the law, used our services unlawfully (for example calling or messaging people without the required consent), or because of content you provided.

17. Suspension and termination

We may suspend or end your access if you break these terms, if you do not pay, or if your use puts our systems, other customers or the public at risk. Where reasonable, we will warn you first. You can stop using the website at any time; ending a paid service follows your agreement. Sections that by their nature should continue after termination, such as fees owed, confidentiality, intellectual property, liability limits and indemnity, will continue.

18. Events outside our control

Neither side is responsible for delays or failures caused by events outside its reasonable control, such as power outages, internet or telecom carrier failures, natural disasters, war, strikes or government action.

19. Governing law and disputes

These terms are governed by the laws of the Islamic Republic of Pakistan. If a dispute arises, both sides will first try to settle it in good faith within 30 days of written notice. If that fails, the dispute will be settled by arbitration under the Arbitration Act, 1940, before a single arbitrator agreed by both sides, in English, seated in Karachi. The arbitrator’s award will be final and binding. Either side may still ask the courts at Karachi for urgent relief, such as an injunction.

20. Changes to the services and these terms

We may change or withdraw parts of the website or demos at any time. We may also update these terms; the date at the top of this page shows when they last changed. For significant changes that affect paying customers, we will give at least 15 days’ notice by email or in the product. Continuing to use the website or services after a change takes effect means you accept the updated terms.

21. General

These terms, together with any signed agreement, are the whole agreement between us about their subject.
If we do not enforce a right straight away, we have not given it up.
If any part of these terms is found invalid, the rest stays in force.
You may not transfer your rights under these terms without our written consent.
Notices to KHz must be sent to info@khz.blue.

Privacy Policy

This policy explains what personal information KHz collects through khz.blue and when we work with you as a customer, why we collect it, how we protect it, and the choices you have. In short: we collect only what we need, we never sell personal information, and we do not use it for advertising.

1. Who is responsible

Website, demos and our customers’ business contacts: KHz decides how this information is used and is responsible for it (the “controller”).
Data inside KHz products: the business using the product is responsible for its data. KHz handles it only on that business’s instructions (as a “processor”). See section 13.

2. What we collect

Demo requests and enquiries. Your name, phone number, email address, company and the product you are interested in. Our demo form prepares an email from your own email app, so we receive these details by email.
Live demos. The phone number you enter for the call demo, the time of the request and the call result (for example answered, busy or failed). Messages you send in a chat demo.
Customer account and billing information. Business contact details of the people we work with, and invoice and payment records. We do not store full payment card numbers.
Support communications. Emails, calls and messages you send our support team.
Connected channels. When a customer connects a WhatsApp number, Facebook Page or Instagram account to a KHz product, we store the access tokens needed to send and receive messages for that customer.
Technical information. Your IP address, browser and device type, pages visited and time of visit. This is recorded automatically in our web server logs.

3. How we use it

To reply to enquiries and arrange demonstrations and quotations.
To place the demo call or answer the chat you asked for.
To provide, support and bill for the services our customers buy, and to send service notices such as renewals and changes.
To protect the website, demos and services from abuse, fraud and attacks, including limiting repeated demo calls.
To keep our services working and to improve them, using aggregated or anonymised information where possible.
To send news about our products, only if you agreed. Every such email has an unsubscribe link.
To meet our legal obligations.

We rely on one of these reasons:

you asked us to do something, such as a demo;
we have a contract with you;
we have a legitimate business need, such as security;
the law requires it;
you gave your consent, which you can withdraw at any time.

4. AI and automated processing

Some demos and products use AI, for example voice assistants that answer calls, transcription, summaries and call quality scores. AI output can contain mistakes, and our customers are told to have people review it before acting on it. We do not make decisions with legal or similarly significant effects about you based only on automated processing. We do not use one customer’s recordings, transcripts or messages to train AI models for other customers.

5. Who we share it with

We never sell personal information. We share it only with:

service providers who help us run our website, demos and services, such as hosting and data centre, email, telecom carriers and AI providers, only for the work we ask of them and under confidentiality;
authorities, where the law requires it, or to protect the rights and safety of KHz, our users or the public;
a buyer or successor, if KHz is involved in a merger, acquisition or sale of assets, under the same protections described here.

The website loads fonts from Google Fonts, so Google receives your IP address when a page loads.

6. Cookies and tracking

This website does not set cookies, and we do not use advertising, remarketing or analytics tracking. Because we do not track you, there is nothing for a “Do Not Track” signal to switch off. If we ever add cookies or analytics, we will update this policy first.

7. How long we keep it

Demo requests and enquiries: up to 24 months after our last contact with you.
Demo call and chat records: up to 12 months.
Customer account information: for the length of our agreement and up to 6 months after it ends.
Invoices and payment records: as long as tax and accounting laws require.
Server and security logs: up to 90 days, unless needed to investigate abuse.

After these periods, we delete or anonymise the information.

8. How we protect it

Encrypted connections (HTTPS/TLS) for our website and services.
Access only for staff who need it, with separate roles and logins.
Firewalls, monitoring and regular security testing of our systems.
Encrypted backups.

No system is completely secure, but we work to prevent loss, misuse and unauthorised access. We will never ask for your password or one-time codes. To report a security issue, see the Legal Notice below.

9. Your rights

Depending on where you live, you can ask us to:

show you the personal information we hold about you;
correct it if it is wrong;
delete it (see Data Deletion below);
limit or stop how we use it, including for marketing;
give you a copy in a common format;
withdraw a consent you gave.

Email info@khz.blue with the subject “Privacy request”. We may need to confirm your identity first, and we will reply within 30 days. If you are not satisfied, you can complain to the data protection authority where you live.

10. International transfers

We store information mainly on our own servers. Some service providers may process it in other countries, where laws can differ from yours. When that happens, we use providers with appropriate safeguards and share only what is needed.

11. Children

Our website and services are for businesses and are not directed at anyone under 18. We do not knowingly collect information from children. If we learn that we have, we will delete it.

12. Other websites

Our website may link to sites run by others. Their own privacy policies apply, and we are not responsible for how they handle information.

13. Data inside KHz products

When a business uses KHz products, that business decides what data is collected about its own customers and how it is used, including call recordings, transcripts, chat messages and CRM records. KHz processes that data only on the business’s instructions and under our agreement with them. If you are a customer of a business that uses KHz products, please contact that business about your data; we will help them respond.

14. Changes to this policy

We may update this policy. The date at the top of this page shows when it last changed. For significant changes, we will also show a notice on the website and tell our customers by email before the change takes effect.

Data Deletion

You can ask KHz to delete your personal information at any time. This also applies to businesses that connected a WhatsApp number, Facebook Page or Instagram account to a KHz product.

1. How to ask

Email info@khz.blue with the subject “Data deletion request”, and tell us:

your name, and the email address or phone number you used with us;
your company name, if you are a business customer;
any connected WhatsApp number, Facebook Page or Instagram account;
whether you want everything deleted, or only some of it.

We may ask you to confirm that you are the account holder before we delete anything.

2. How long it takes

We will acknowledge your request within 2 working days. We aim to complete it within 7 working days, and always within 30 days. We will email you when it is done.

3. Disconnecting a channel

A business can disconnect a WhatsApp number, Facebook Page or Instagram account at any time:

in the KHz product’s channel settings; or
in the business integrations settings of Facebook or Meta Business.

Disconnecting deletes the access tokens, so we can no longer read or send messages on that channel. It does not delete messages and contacts already stored. To remove those as well, send a deletion request as described above.

4. What we delete

Account and profile details.
Access tokens for connected channels.
Conversation history, messages, contacts and call records we hold for you.
Files and knowledge sources you uploaded, for example for chatbots.

Information is deleted or anonymised so it can no longer identify you. Copies in our encrypted backups are removed as the backups are replaced, within 35 days.

5. What we may keep

We may keep some information when the law requires it or when we need it to settle a dispute or enforce an agreement, for example invoices and payment records. We keep only what is needed, and only for as long as needed.

6. Data held by a business that uses KHz

If a business that uses KHz products holds your data, for example a recording of your call with them, please ask that business first. They control that data, and we will help them carry out your request.

1. Licensed, not sold

KHz software is licensed to your organisation, not sold. You may use it only within the modules, channels, users and term your organisation has licensed. Each channel and additional feature needs its own licence.

upload malicious code or overload the system on purpose.

5. AI output

AI features can make mistakes. Review transcripts, summaries, sentiment and quality scores before using them for decisions about staff or customers.
