How tool input is handled
Where possible, tools process data in the browser. Some tools use the Website API and send input to the server to calculate a result. We do not intentionally use tool input for advertising profiling. Tool input may still appear in transient request processing, security logs or error diagnostics where technically necessary.
Cookies and consent
We use a cookie consent banner with Necessary, Preferences, Analytics and Marketing categories. Optional analytics and advertising technologies are not enabled until the corresponding consent is granted. More details are available in the Cookie Policy.
Recipients and processors
We may use hosting, email, logging, analytics, advertising and infrastructure providers. Planned or possible providers include Google services (Google Analytics and Google AdSense) and Yandex services (Yandex Metrica and Yandex Advertising Network), only according to your consent and configuration. We may disclose data if required by law or to protect our rights, users or the Website.
International transfers
We are based in Serbia and may use service providers in other countries. Where data protection laws require safeguards for international transfers, we rely on appropriate measures such as contractual safeguards, adequacy mechanisms or provider compliance frameworks where available.
Retention
- Account data is kept while the account exists and for a reasonable period after deletion if needed for security, legal or dispute purposes.
- Contact messages are kept as long as needed to handle the request and maintain business records.
- Server logs and security records are kept for a limited period needed for security, debugging and abuse prevention.
- Cookie consent and preference data remain in your browser until you change settings, delete browser storage or the consent version changes.

Depending on your location, you may have rights to access, correct, delete, restrict or object to processing, portability, withdraw consent and complain to a data protection authority. Withdrawing consent does not affect processing that happened before withdrawal.

Security
We use reasonable technical and organizational measures to protect data. No internet service can guarantee absolute security.
