Privacy Policy

Data controller

The controller is Konstantīns Pobilojs, operating Calcufetti.

Data we process

Depending on how you use Calcufetti, we may process:

• account data such as email address, password hash, verification status and security timestamps;
• calculations that you explicitly choose to save to your account;
• feedback messages, optional contact details and calculator values only when you expressly choose to attach them;
• technical security data such as IP address, user agent, request metadata and server error logs.

Calculator inputs are not sent to advertising or analytics services. Calcufetti does not sell personal data.

Purposes and legal bases

• Providing accounts, saved calculations and requested features: performance of the service requested by you.
• Protecting accounts, preventing abuse and diagnosing failures: our legitimate interest in operating a secure and reliable service.
• Meeting legal obligations and responding to lawful requests: compliance with applicable law.
• Attaching optional calculator values to feedback: your consent, which you may withdraw for future processing.

Privacy-friendly web analytics

Calcufetti uses Cloudflare Web Analytics on public, indexable pages to understand aggregate visits and real-user page performance. The analytics beacon is not loaded on account, authentication, password-reset, email-verification or feedback routes.

According to Cloudflare, Web Analytics does not use cookies or local storage to collect usage metrics, does not track individual end users across Cloudflare customers' sites, and does not collect or use visitors' personal data for Web Analytics. Calculator input values are not sent to Cloudflare Web Analytics.

Retention

• Unverified accounts are deleted after 30 days.
• Active accounts and saved calculations remain until you delete them or close the account.
• Deleted data expires from backups within 30 days.
• Feedback is retained for up to 12 months.
• Security and server logs are normally retained for 30 days, unless an incident requires longer preservation.

Service providers and international transfers

Calcufetti uses service providers for hosting, databases, backups and transactional email, and Cloudflare Web Analytics for aggregate public-page usage and performance measurement. The launch configuration prefers processing in the EU or EEA where the relevant service supports it. If a provider processes personal data outside the EEA, Calcufetti uses an applicable transfer mechanism and documents the transfer.

Cookies and local storage

Calcufetti uses only storage required to provide requested functionality, maintain sessions and protect forms and accounts. Optional advertising cookies are not used. Cloudflare Web Analytics does not use cookies or local storage to collect usage metrics.

Your rights

Subject to the conditions in applicable law, you may request access, correction, deletion, restriction, portability or objection, and may withdraw consent where processing is based on consent. Contact privacy@calcufetti.com.

Under Article 77 of the GDPR, you may also lodge a complaint with a competent data-protection supervisory authority.

Automated decisions and children

Calcufetti does not use personal data for automated decisions with legal or similarly significant effects. The service is not designed to collect special-category profiles or data from children.
