- use this website;
- submit an enquiry or service request;
- accept a quotation or proposal;
- make full or partial payment;
- give us instructions to proceed;
- electronically approve documents or deliverables; or
- enter into another service arrangement with One Crystal.
Electronic communications, approvals and records may be used in connection with our services in accordance with applicable Tanzanian law.
3. Website Use
You may use this website only for lawful purposes.
You must not:
- provide false, fraudulent or misleading information;
- impersonate another person or organisation;
- attempt to gain unauthorised access to our website or systems;
- interfere with website security or functionality;
- upload malicious software;
- use our content without permission;
- infringe intellectual property rights;
- use our services for unlawful activities; or
- engage in conduct reasonably capable of harming One Crystal, its clients or third parties.
We may restrict access or refuse service where misuse, illegality, fraud or security risk is reasonably suspected.
4. Website Information
Information published on this website is provided for general information about One Crystal and its services.
Although reasonable efforts are made to keep information accurate and useful, laws, regulations, government procedures, statutory charges, administrative practices, technology and third-party services may change.
Website information therefore does not constitute:
- a guaranteed quotation;
- a guarantee of government approval;
- a final legal determination;
- a guarantee of registration;
- a guarantee of completion within a particular period; or
- professional advice tailored to a specific matter unless expressly stated.
Where information on the website differs from a specific quotation, agreement, proposal or written instruction relating to a client's engagement, the specific engagement document will prevail.
5. Formation of a Service Engagement
Submitting an enquiry does not automatically create a professional engagement.
An engagement generally begins after One Crystal accepts the client's instructions and any applicable requirements have been satisfied.
These may include:
- acceptance of a quotation;
- payment of a required fee or deposit;
- submission of required documents;
- completion of onboarding or verification requirements; or
- execution of a service agreement.
We reserve the right to accept or decline any engagement.
6. Client Responsibilities
Clients must provide accurate, complete and current information necessary for the requested service.
Clients are responsible for reviewing and confirming important details before submission, publication, printing, deployment or regulatory filing.
This may include:
- names;
- identification details;
- contact information;
- addresses;
- company details;
- directors and shareholders;
- beneficial owners;
- business activities;
- trademarks;
- logos;
- product or service descriptions;
- project specifications;
- financial information;
- regulatory information; and
- other relevant documents.
One Crystal may reasonably rely upon information supplied by the client.
We are not responsible for loss, rejection, penalties, delay or additional costs resulting from inaccurate, incomplete, misleading, fraudulent or late information provided by the client.
7. Regulatory and Government Services
Some One Crystal services involve applications, registrations, filings, renewals, searches, licences, approvals or other interactions with government authorities and regulatory bodies.
One Crystal may act as a consultant, facilitator, representative or service provider according to the engagement.
Final decisions remain with the responsible authority.
One Crystal therefore cannot guarantee:
- approval of an application;
- registration of a company or business name;
- issuance of a licence or permit;
- registration or grant of intellectual property;
- acceptance of a proposed name;
- acceptance of a regulatory filing;
- absence of objections;
- completion within a particular government processing period; or
- any particular decision by a competent authority.
Our responsibility is to perform the agreed services with reasonable skill, care and diligence.
8. Intellectual Property Services
Searches, classifications, opinions or preliminary assessments involving trademarks, patents, industrial designs or other intellectual property are based on information reasonably available at the relevant time.
A search or assessment does not guarantee:
- registration;
- grant;
- successful examination;
- absence of third-party rights;
- absence of opposition; or
- a favourable decision from the relevant authority.
Where objections, oppositions, office actions, hearings, appeals or additional regulatory work arise, additional fees may apply unless those services were expressly included in the original engagement.
9. Creative Services
The scope of a creative project may specify:
- concepts;
- revisions;
- deliverables;
- formats;
- production specifications; and
- approval stages.
Requests outside the agreed scope may be treated as additional work.
Clients must ensure that photographs, logos, music, fonts, videos, text, trademarks or other materials supplied to One Crystal may lawfully be used.
One Crystal is not responsible for third-party claims arising solely from unlawful or unauthorised material supplied by the client.
Public Testimonial Submissions
Where a person submits a testimonial through the website, submission does not guarantee publication. One Crystal may verify, review, edit for length or clarity without changing the meaning, approve, decline or remove a testimonial.
Contact details supplied for verification are not intended for public display. A submitted name, role, organisation, rating, testimonial and approved photograph or company logo may be published only in accordance with the permission given by the person submitting the material.
Requests to correct or remove a published testimonial may be sent to administration@onecrystal.co.tz.
10. Technology Services
Website, software, mobile application and ICT projects may be governed by separate project specifications or agreements.
These may cover:
- deliverables;
- functionality;
- milestones;
- development phases;
- hosting;
- maintenance;

Depending on the service, we may require:
- full advance payment;
- a deposit;
- milestone payments; or
- final payment before delivery, submission, deployment or release.
One Crystal may suspend work where payment is overdue.
Unless agreed otherwise, the client is responsible for transaction costs such as bank charges, international-transfer charges or currency-conversion fees.
13. Client Approval
Where One Crystal sends documents, forms, applications, designs, specifications or other material for approval, the client is responsible for reviewing them carefully.
Approval through email, electronic communication, electronic signature or another agreed digital method may be treated as valid authority to proceed.
Once a client approves a document or deliverable, any later correction caused by information previously confirmed by the client may constitute additional work.
14. Intellectual Property Rights
Unless otherwise agreed, One Crystal retains rights in its own:
- name and trademarks;
- branding;
- website;
- templates;
- methodologies;
- reusable code;
- frameworks;
- development tools;
- libraries;
- internal systems;
- know-how; and
- pre-existing materials.
Ownership or licensing of work specifically commissioned by a client will be determined by the applicable agreement.
Third-party resources remain subject to their respective licences.
15. Confidentiality
One Crystal will take reasonable measures to protect confidential information supplied by clients.
Information may nevertheless be disclosed where:
- the client authorises disclosure;
- disclosure is necessary to provide the agreed service;
- information must be submitted to an authority;
- disclosure is required by law;
- disclosure is required by a lawful court or regulatory order; or
- disclosure to a professional adviser or service provider is reasonably necessary.

One Crystal is not responsible for failure or interruption occurring entirely within systems outside our reasonable control.

This includes, where applicable:

Such circumstances may include natural disasters, government action, system failure, power interruption, telecommunications failure, cyber incidents, civil disturbance, regulatory interruption or comparable events.
