5. Legal Bases and Consent

Where required by applicable law, we process personal information only where we have a valid legal basis, such as:

• your consent;
• performance of a contract with you;
• compliance with legal obligations; or
• our legitimate interests in operating, securing, and improving the Service, provided those interests are not overridden by your rights.

Where consent is required, you may withdraw it at any time, subject to applicable law and the continued lawfulness of prior processing.

6. Shared Content and Visibility

LingvoBoss may allow users to upload their own texts and share them with others.

If you choose to share content, please understand:

• shared content may be visible to other users according to your selected sharing settings and the Service’s functionality;
• other users may be able to view, copy, save, or reuse content you share;
• we cannot guarantee that other users will always follow your preferences once they have gained access to shared content; and
• you should not upload or share confidential, sensitive, proprietary, or personal information unless you accept the risks associated with disclosure.

You are responsible for the content you choose to upload and share.

7. How We Share Information

We may share personal information in the following circumstances:

7.1 Service Providers

We may share information with contractors, vendors, and service providers who perform services on our behalf, such as hosting, cloud storage, analytics, authentication, customer support, communications, payment processing, or security monitoring.

These parties may access personal information only as needed to perform services for us and subject to appropriate obligations.

7.2 Other Users

If you choose to share content publicly or with other users, your content and related profile information may be visible to those users.

7.3 Legal Requirements and Protection

We may disclose information if we believe in good faith that disclosure is necessary to:

• comply with applicable law, regulation, court order, or lawful government request;
• enforce our Terms or other agreements;
• protect the rights, property, or safety of LingvoBoss, our users, or others; or
• detect, prevent, or address fraud, abuse, security, or technical issues.

7.4 Business Transfers

If LingvoBoss is involved in a merger, acquisition, financing, reorganization, sale of assets, or similar transaction, information may be transferred as part of that transaction, subject to applicable law.

7.5 With Your Consent

We may share information in other circumstances where you have given consent.

8. Children’s Privacy

The Service is not intended for children where collection of their personal information would require parental consent under applicable law, unless such consent has been properly obtained.

If you are a parent or legal guardian and believe that a child has provided us with personal information in violation of applicable law, please contact us at support@lingvoboss.com. We will take reasonable steps to investigate and, where appropriate, delete the information.

9. Analytics, Advertising, and Third-Party Features

We may use third-party analytics tools and similar services to better understand how users interact with the Service, improve functionality, and measure performance.

If we display advertising or use advertising-related services, those providers may use cookies or similar technologies to provide, measure, or personalize ads, subject to their own privacy policies and applicable law.

The Service may also contain third-party links, login tools, widgets, or integrations. Your interactions with those third-party services are governed by their own terms and privacy policies, not this Privacy Policy.

10. Payments

If the Service offers paid features, purchases may be processed by third-party payment providers or platform operators, such as app stores or payment processors.

We do not necessarily store your full payment card details on our own servers. Payment information is generally handled by the relevant payment provider in accordance with its own privacy policy and security practices.

11. Data Retention

We retain personal information for as long as reasonably necessary for the purposes described in this Privacy Policy, including to:

• provide the Service;
• maintain your account;
• preserve user content and sharing functionality;
• comply with legal obligations;
• resolve disputes; and
• enforce our agreements.

If you delete your account or request deletion of your information, we will delete or anonymize relevant information within a reasonable time, except where retention is necessary for legal, security, backup, fraud prevention, or legitimate operational reasons.

12. Security

We take reasonable technical and organizational measures designed to protect personal information against unauthorized access, loss, misuse, alteration, or disclosure.

However, no method of transmission over the internet or electronic storage is completely secure. Therefore, while we strive to protect your information, we cannot guarantee absolute security.

13. International Transfers

Your information may be processed in countries other than your own, including where our service providers operate. Where required by applicable law, we take appropriate steps to ensure that such transfers are subject to adequate safeguards.

14. Your Rights and Choices

Subject to applicable law, you may have the right to:

• access the personal information we hold about you;
• request correction of inaccurate or incomplete information;
• request deletion of your personal information;
• object to or restrict certain processing;
• withdraw consent where processing is based on consent;
• request portability of your information; and
• opt out of marketing communications.

You may also be able to review, edit, or delete certain account information directly through your account settings.

To exercise privacy-related rights, please contact us at support@lingvoboss.com. We may request information necessary to verify your identity before processing your request.

15. Account and Content Controls

You remain in control of much of the information you provide through LingvoBoss.

Depending on the functionality of the Service, you may be able to:

• review and edit profile information;
• change sharing settings for your texts and other content;
• delete certain uploaded content;
• stop receiving marketing emails by using the unsubscribe link or contacting us; and
• delete your account.

Please note that deleting content or your account may limit your ability to use certain parts of the Service, and some residual copies may remain for legal, backup, or security reasons for a limited period.

16. Data Breach Response

We comply with applicable laws relating to security incidents and personal data breaches. If we are required by law to notify you of a breach affecting your personal information, we will do so within the timeframe and in the manner required by applicable law.

17. Changes to This Privacy Policy

We may update this Privacy Policy from time to time.

If we make material changes, we may provide notice through the Service, by email, or by other reasonable means before the changes become effective, where required by law.
