Privacy Policy

1. Introduction

BTTOTEK Solutions provides online calculators, articles and related website features for civil construction, engineering estimation, property and real-estate calculations.

This Privacy Policy explains what information may be collected when you use our website, how that information may be used, and the choices available to you.

2. What This Policy Covers

This policy applies to information processed through the BTTOTEK website, including calculator pages, account features, contact forms, analytics and advertising features that are actually enabled.

Some calculators can be used without an account. Where a feature does not require personal information, users can generally use it without submitting identifying details.

4. Calculator Information

Many BTTOTEK calculators perform calculations directly in your web browser. Information entered into a calculator is generally processed in your browser for the calculation and may remain in browser memory or local storage depending on the feature. Do not assume that every calculator is a private or permanent data store.

If a particular feature allows you to save information to an account or workspace, information submitted through that feature may be stored so that you can access it later.

Users should avoid entering confidential, sensitive or commercially secret information unless the relevant feature clearly requires it and the user is comfortable with its storage.

4. Account Information

If you create an account, we may collect information such as your email address and other information that you voluntarily provide for account or workspace functionality.

This information may be used to authenticate your account, provide requested features, maintain your workspace and communicate with you about your account.

5. Contact Form Information

When you submit our contact form, we may collect the name, email address, phone number and message that you provide.

We use this information to respond to your enquiry, provide support, investigate reported problems and communicate about your request.

Please do not submit passwords, financial account credentials, confidential tender information or other sensitive information through the contact form.

6. Cookies and Local Storage

BTTOTEK may use cookies, local storage and similar technologies for essential website functionality, authentication, preferences and security.

For example, browser storage may be used to remember interface preferences such as theme settings. Authentication-related technologies may be used when you sign in to your account.

Some third-party services used on the website may also use cookies or similar technologies according to their own policies.

7. Google Analytics

Where Google Analytics is enabled on the website, BTTOTEK may use it to understand how visitors use the website, such as which pages are visited and how users interact with the site.

Google Analytics may collect information such as device information, browser information, approximate location and website interaction data. This information is used for website measurement and improvement.

Google processes information according to its own policies and terms. Users can learn more about Google's privacy practices through Google's official privacy resources.

8. Advertising & Google AdSense

Where advertising is enabled, BTTOTEK may display advertisements provided by third-party advertising vendors and ad networks, including Google AdSense.

Third-party vendors, including Google, use cookies, device identifiers and similar technologies to serve ads based on a user's prior visits to this website or other websites on the Internet.

Google's use of advertising cookies enables it and its partners to serve ads to our users based on their visit to BTTOTEK and/or other websites across the Internet.

Users may opt out of personalized advertising by visiting Google Ads Settings at https://adssettings.google.com (or https://www.google.com/settings/ads).

Alternatively, users can opt out of a third-party vendor's use of cookies for personalized advertising by visiting the Network Advertising Initiative (NAI) opt-out page or the Digital Advertising Alliance (DAA) choices page at https://www.aboutads.info/choices/.

Advertising preferences and cookie settings may vary depending on your browser settings, geographical location, consent management choices, and ad network configurations.

BTTOTEK does not sell personal user information, nor do we provide the contents of your private saved calculations, structural estimations or contact form submissions to advertising providers for advertising purposes.

9. Third-Party Services

The website may use third-party services for hosting, authentication, analytics, database functionality, advertising and other technical operations.

These providers may process information on our behalf or independently according to their own terms and privacy policies.

We aim to use reputable services and only enable third-party functionality that is necessary for operating or improving the website.

10. How Information Is Used

Information may be used to operate and maintain the website, provide requested services, authenticate accounts, respond to enquiries, improve calculators and website performance, understand website usage, prevent abuse and comply with applicable legal obligations.

We do not sell your personal information to third parties.

11. Data Security

We take reasonable technical and organisational measures to protect information handled through the website. However, no internet transmission or electronic storage system can be guaranteed to be completely secure.

Users should therefore avoid submitting highly sensitive information through public website forms.

12. Data Retention

Information may be retained for as long as reasonably necessary to provide the requested service, maintain an account, respond to enquiries, maintain security, comply with legal obligations or resolve disputes.

Retention periods may vary depending on the type of information and the purpose for which it was collected.

13. Your Choices and Rights

Depending on your location and applicable law, you may have rights relating to access, correction, deletion, restriction or other processing of your personal information.

You can contact us through our Contact page to ask questions about personal information associated with your account or enquiries. We may need to verify a request before acting on it, where permitted or required by law.

14. Children's Privacy

BTTOTEK is primarily intended for general users, professionals and adults interested in construction, engineering and property-related information. We do not knowingly request personal information from children for purposes that are prohibited by applicable law.

15. External Links

Our website may contain links to external websites or services. We are not responsible for the privacy practices, security or content of websites that we do not operate.

We recommend reviewing the privacy policy of any external website before providing personal information.

16. Changes to This Privacy Policy

We may update this Privacy Policy when our website, services, analytics, advertising or legal requirements change.

When changes are made, the updated version will be published on this page together with an updated effective date.
