Privacy

Last updated: 25 August 2026.

One Crystal Company Limited respects the privacy of visitors, clients, prospective clients and other people who communicate with us through this website. This notice explains how we collect, use, store, disclose and protect personal data in connection with the website and our consultation enquiries.

For purposes of this notice, personal data means information that identifies or can reasonably identify an individual. This may include your name, telephone number, email address, organisation, service interest, message content, consultation details, communication records and technical information generated when you use the website.

We collect personal data when you submit a contact or consultation form, contact us by email, telephone or WhatsApp, request information about our services, apply for training or events, or otherwise choose to provide information to us. We may also receive limited technical information such as browser type, device information, IP address, pages visited and time of access where this is generated by hosting, security or analytics tools.

We use personal data to respond to enquiries, assess consultation requests, provide requested information, manage client communications, prepare proposals, deliver agreed services, improve the website, protect the security of our systems, keep business records and comply with applicable legal or regulatory obligations.

We process personal data only where there is a lawful and legitimate reason to do so, including where you have requested communication from us, where processing is necessary before or during a service engagement, where we must comply with a legal obligation, where processing is necessary for our legitimate business interests, or where you have given consent for a specific purpose.

We do not sell personal data. We may share personal data with authorised personnel, professional advisers, service providers who support hosting, email, security, analytics or business operations, and public authorities, regulators or courts where disclosure is required by law or necessary to protect legal rights.

Some service providers or digital tools used to operate this website may process data outside Tanzania. Where personal data is transferred or accessed outside Tanzania, we aim to apply appropriate safeguards and comply with applicable requirements under Tanzanian personal data protection law.

We retain personal data only for as long as reasonably necessary for the purpose for which it was collected, including responding to enquiries, maintaining business records, resolving disputes, meeting legal obligations and protecting our lawful interests. Retention periods may differ depending on the nature of the information and the relationship involved.

We use reasonable technical and organisational measures to protect personal data against unauthorised access, loss, misuse, alteration or disclosure. No internet transmission or electronic storage system can be guaranteed to be completely secure, so users should avoid submitting unnecessary sensitive information through general website forms.

Depending on the circumstances and applicable law, you may request access to your personal data, correction of inaccurate data, deletion or restriction of processing, objection to certain processing, withdrawal of consent where processing is based on consent, or information about how your data has been used or disclosed.

If you believe your personal data has been handled improperly, you may contact us first so we can review the matter. You may also have the right to lodge a complaint with the Personal Data Protection Commission of Tanzania.

This website is not directed to children. We do not knowingly collect personal data from children through the website. If we become aware that a child has submitted personal data without appropriate authority, we will take reasonable steps to address it.

This website may use necessary cookies or similar technologies for security, performance or functionality. If optional analytics or marketing cookies are introduced, this notice should be updated to explain those tools and any choices available to users.

For privacy questions or requests, contact One Crystal Company Limited through taarifa@onecrystal.co.tz or the contact details published on this website.

We may update this privacy notice from time to time to reflect changes in our operations, website features, service providers or applicable law. The updated version will be posted on this page with a revised date.
