Lucio uses artificial intelligence to personalize parts of the Service. This section explains how.

Features that use AI:

AI processors we use:

Important facts:

Automated decision-making under GDPR Art. 22: AI-driven recommendations in Lucio do not produce legal or similarly significant effects on you, and therefore do not constitute "solely automated decision-making with legal effect" under GDPR Article 22. You can always disregard AI outputs and are never required to follow them.

6. How We Share Personal Information

We share personal information only as described below.

Service providers (processors). We share personal information with vendors who provide infrastructure, AI, analytics, payments, or customer support on our behalf. These providers may access only the information they need to perform their services, and they are bound by contractual data-processing obligations.

Affiliates and business transfers. We may share information with affiliated entities or in connection with a merger, acquisition, reorganization, or sale of assets. In any such transaction, we will ensure the recipient is bound by commitments consistent with this Policy.

Legal and safety. We may disclose information where we reasonably believe disclosure is required by law, to respond to lawful requests from authorities, to protect our rights or property, or to protect the safety of users or the public.

With your consent or at your direction. We share information with other parties only when you ask us to or consent.

Aggregated or de-identified data. We may share aggregated or de-identified information that cannot reasonably identify you.

We do not sell your personal information. We do not share your personal information for cross-context behavioral advertising as defined under the CCPA/CPRA. We have not sold or shared the personal information of California consumers in the preceding 12 months.

8. Cookies, SDKs, and Similar Technologies

Lucio is a native mobile application and does not use web cookies in the traditional sense. The Service incorporates software development kits (SDKs) from the processors listed in Section 7. These SDKs may collect device identifiers, IP addresses, and usage events to perform their function (analytics, error reporting, subscription management, authentication). We do not use any SDK to link your activity to third-party data for cross-context behavioral advertising.

9. International Data Transfers

Personal information is processed in the United States (by our primary processors) and in the Republic of Serbia (by us as the controller). If you are located in the European Economic Area, the United Kingdom, or Switzerland, your personal information is transferred outside those regions.

We rely on the following safeguards for international transfers:

If you are located in the Russian Federation, by using the Service you provide your explicit consent to the cross-border transfer and processing of your personal information outside the Russian Federation (including the Republic of Serbia and the United States). We do not maintain servers in the Russian Federation; if you do not consent to such transfer, you must not use the Service.

You may request a copy of the safeguards applicable to your data by emailing s.yousupov@gmail.com.

14. Changes to This Policy

We may update this Policy from time to time. If we make material changes, we will notify you by email or through an in-app notice before the changes take effect.

15. Regional Disclosures

15.1 European Union — Article 27 Representative

At this time the Service is offered to a relatively small, non-commercial-advertising audience and we rely on the derogation in Article 27(2)(a) of the GDPR. If and when our EU user base grows to the point that an Article 27 representative is required, we will appoint one and update this Policy. EU users may contact us directly at s.yousupov@gmail.com regarding any GDPR matter.

15.2 California — "Shine the Light"

California residents may request a list of categories of personal information we have disclosed to third parties for their direct marketing purposes in the preceding calendar year. Lucio does not disclose personal information to third parties for their own direct marketing purposes.

The Service is made available in the Russian Federation for personal use; however, we do not actively market the Service within Russia. By using the Service in Russia, you provide your explicit consent to the collection, processing, and cross-border transfer of your personal data as described in this Policy (Federal Law No. 152-FZ). If you do not consent, you must not use the Service.
