Welcome to Oi Technologies. These Terms of Service (“Terms”) govern your access to and use of our website, mobile applications, software and IT-enabled services (together, the “Services”).

These Terms form a legally binding agreement between you (“you” or “User”) and Oi Technologies (“we”, “us”, “our” or the “Company”). By accessing or using the Services, you agree to be bound by these Terms, our Privacy Policy, Payment Policy, Refund and Cancellation Policy and Transparency Report. If you do not agree, please do not use the Services.

1. About Us and Current Status

Current status:

  • All Oi apps are completely free to use. There are no in-app purchases, subscriptions or hidden charges.
  • Our apps do not require you to create an account or provide personal information.
  • Our software, website, mobile app development and other IT services are paid services, governed by our Payment Policy and our Refund and Cancellation Policy.

2. Acceptance of Terms

If you are 13 to 17 and wish to use them, you may do so only with the explicit consent and supervision of a parent or legal guardian who agrees to these Terms on your behalf. We strongly encourage parents and guardians to monitor their children’s use.

6. User Content

The Services may let you upload, transmit or otherwise make available data, text or other content (“User Content”).

  • Ownership: You keep all ownership rights in your User Content.
  • License to us: You grant Oi Technologies a worldwide, non-exclusive, royalty-free, fully paid licence to host, store, use, display and modify your User Content solely to the extent necessary to provide the Services to you.

Violating these restrictions may lead to immediate suspension or termination, and we may pursue legal action where necessary. These restrictions do not apply to good-faith security research carried out in accordance with our Vulnerability Disclosure Policy.

8. Third-Party Links and Services

The Services may contain links to third-party websites, payment gateways or external services, such as social media platforms. These are provided for your convenience only. We do not control or endorse them, and we are not responsible for their content, privacy practices, security or terms. Please review their policies before sharing personal data or using their services.

9. Pricing, Payments and Refunds

Free apps: All Oi Technologies applications are free to use. There are no in-app purchases, subscriptions or hidden charges.

Paid services: Our software, website, mobile app development and other IT services are paid services.

  • Prices, accepted payment methods (Pay on Delivery, bank transfer and Bangla QR), payment schedules and taxes are set out in our Payment Policy and in the quotation or invoice we send you.
  • Cancellations and refunds are governed by our Refund and Cancellation Policy.
  • If we introduce paid features, premium tiers or subscriptions in our apps in the future, we will tell you the pricing, billing cycle and payment methods in advance and update our policies before you make any transaction.

10. Disclaimer of Warranties

Your use of the Services is at your own risk. The Services are provided on an “AS IS” and “AS AVAILABLE” basis, without warranties of any kind, whether express, implied or statutory.

To the fullest extent permitted by law, Oi Technologies does not warrant that:

  • The Services will be uninterrupted, error-free, secure or always available.
  • Any specific results or performance levels will be achieved.
  • Any third-party data, links or integrations are accurate, reliable or complete.

We make reasonable efforts to maintain the Services, but technical issues, maintenance or unforeseen circumstances may cause temporary interruptions, for which we are not liable.

11. Limitation of Liability

To the maximum extent permitted by law, Oi Technologies, its directors, employees, agents and affiliates are not liable for:

  • Direct, indirect, incidental, special, consequential or punitive damages arising from your use of, or inability to use, the Services.
  • Loss of data, profits, revenue, business opportunities or goodwill.
  • Damage resulting from unauthorized access to, or alteration of, your data by third parties beyond our reasonable control.

Our total aggregate liability for any claim arising out of or relating to these Terms will not exceed the amount you paid us for the specific service that gave rise to the claim. Because our apps are free, our liability for claims relating only to the free apps is zero (0) BDT.

12. Indemnification

You agree to defend, indemnify and hold harmless Oi Technologies and its employees, officers, directors and agents from all claims, damages, obligations, losses, liabilities, costs and expenses (including legal fees) arising from:

  • Your use of and access to the Services.
  • Your violation of these Terms.
  • Your violation of any third-party right, including copyright, property or privacy rights.
  • Any claim that your User Content caused damage to a third party.

This obligation survives the end of these Terms and your use of the Services.

13. Governing Law and Jurisdiction

These Terms, and any dispute arising out of or in connection with them, are governed by the laws of the People’s Republic of Bangladesh. Any legal action relating to these Terms must be brought exclusively in the courts of Bangladesh, and you consent to the jurisdiction of those courts.

14. Legal Requests for Your Data

We do not share your Personal Data with third parties indiscriminately. If a court, law enforcement agency or government authority in Bangladesh makes a legally valid request for your data, we will verify it and, to the extent the law permits:

  • Notify you within 72 hours of receiving the request.
  • Wait at least 7 days before disclosing, so you can challenge the request in court or seek other legal remedies.
  • Tell you who requested the data, what data was requested and when it will be disclosed.

Exceptions. We may disclose data without prior notice only if the law prohibits notification (for example, a gag order) or there is an emergency involving a risk of death or serious physical harm. In such cases we will notify you as soon as we lawfully can.

This section covers legal disclosure requests. For data breach notification, see Section 8 of our Privacy Policy.

15. Changes to These Terms

We may update these Terms to reflect changes in our business practices, legal requirements or operations. When we do:

  • We will update the “Last modified” date at the top of this page.
  • For significant changes, we will notify users through our website, in-app notifications or email.

Continuing to use the Services after changes means you accept the updated Terms. Please review them periodically.

16. Suspension and Termination

We may suspend or terminate your access immediately and without prior notice if:

  • You have materially breached these Terms, including the prohibited uses.
  • We reasonably believe your actions may harm our systems, other users or our reputation.
  • We are required to do so by law or a regulatory authority.
  • We learn that a user under 18 is using our Services without verifiable parental or guardian consent.

On termination, your right to use the Services ends immediately, and we may delete or anonymize your data in line with our Privacy Policy.

17. Entire Agreement and Severability

These Terms, together with our Privacy Policy, Payment Policy, Refund and Cancellation Policy and Transparency Report, are the entire agreement between you and Oi Technologies regarding the Services and replace any earlier oral or written agreements or understandings.

If a court of competent jurisdiction finds any provision invalid, unlawful or unenforceable, that provision will be severed and the rest of these Terms will remain in full force.

18. Contact Us and Grievance Redressal

If you have questions, concerns, disputes or requests about these Terms, your data or the Services, contact our Privacy Office at [email protected] or through our Contact Us page.
