SikaNomics ("we," "us," or "our") respects your privacy and is committed to protecting your personal data. This Privacy Policy explains how we collect, use, store, and share information when you use the SikaNomics web application and related services (the "Service").

By accessing or using the Service, you consent to the practices described in this Privacy Policy. If you do not agree with this Privacy Policy, please do not use the Service. This policy should be read together with our Terms of Service.

1. Information We Collect

We collect the following categories of information:

2. How We Use Your Information

We use the information we collect for the following purposes:

• to provide, operate, and maintain the Service, including authentication, transaction tracking, goal management, and financial analytics;
• to personalize your experience, such as displaying your preferred currency and theme;
• to generate aggregated insights and analytics from your financial data (visible only to you);
• to communicate with you about service-related matters, including security alerts;
• to detect, prevent, and address technical issues, fraud, and security threats;
• to comply with legal obligations and enforce our Terms of Service.

We do not use your personal financial data for advertising, marketing to third parties, or profiling purposes.

3. Legal Basis for Processing

Where applicable data-protection laws require a lawful basis for processing (such as the General Data Protection Regulation), we rely on the following:

• Consent — you provide consent by creating an account and using the Service;
• Contractual necessity — processing is necessary to deliver the Service under our Terms;
• Legitimate interests — we process usage data to improve, secure, and monitor the Service.

4. Data Storage & Security

Your data is stored using secure cloud infrastructure that provides encryption at rest and in transit. While we implement reasonable administrative, technical, and physical safeguards to protect your information, no method of electronic transmission or storage is 100% secure. We cannot guarantee absolute security.

We retain your data for as long as your account remains active or as needed to provide the Service. Upon account deletion, we will delete or anonymize your personal data within a reasonable timeframe, unless retention is required by law.

5. Data Sharing & Disclosure

We do not sell, rent, or trade your personal data. We may share your information only in the following circumstances:

• Service providers — with third-party vendors who assist in operating the Service (e.g., cloud hosting and authentication providers). These providers are bound by their own privacy and security obligations;
• Legal compliance — when required by law, regulation, legal process, or governmental request;
• Protection of rights — to enforce our Terms, protect our rights or safety, or investigate potential violations;
• Business transfers — in connection with a merger, acquisition, or sale of assets, your data may be transferred as part of that transaction, and you will be notified of any changes.

6. International Data Transfers

Your data may be processed and stored in jurisdictions outside your country of residence, including the United States, where Google's infrastructure is located. By using the Service, you consent to such transfers. Where required, we ensure appropriate safeguards are in place (such as Standard Contractual Clauses) to protect your data in accordance with applicable law.

7. Your Rights

Depending on your jurisdiction, you may have the following rights regarding your personal data:

• Access — request a copy of the personal data we hold about you;
• Correction — request correction of inaccurate or incomplete data;
• Deletion — request deletion of your personal data ("right to be forgotten");
• Portability — request your data in a structured, machine-readable format;
• Restriction — request that we limit processing of your data in certain circumstances;
• Objection — object to processing based on legitimate interests;
• Withdraw consent — withdraw consent at any time where processing is based on consent (this does not affect prior lawful processing).

To exercise any of these rights, please contact us using the details in Section 11. We will respond within the timeframes required by applicable law.

8. Children's Privacy

The Service is not directed to children under the age of 16. We do not knowingly collect personal data from children under 16. If we become aware that we have collected data from a child under 16, we will take reasonable steps to delete such information promptly. If you believe a child has provided us with personal data, please contact us.

9. Third-Party Links & Services

The Service may contain links to third-party websites or services. We are not responsible for the privacy practices or content of those third parties. We encourage you to review the privacy policies of any third-party services you access through the Service.
