Privacy and Data Protection Policy

Datafindex is an independent financial analytics and simulation platform. By architectural design, our simulators and calculators operate under the Privacy by Design principle. All numerical computations of interest, contributions, and returns entered into public tools are executed directly in the browser runtime, completely anonymous and without compulsory central database persistence.

We strictly process data essential for platform operations and user support:

• Communication and Support Data: Name, email address, and optional screenshot attachments voluntarily submitted via technical support or bug report channels, strictly used to resolve inquiries and improve reliability.
• Technical Navigation and Diagnostic Data: Anonymized IP address, browser type, operating system, and interaction events captured through telemetry (PostHog and Sentry) to monitor runtime exceptions, response latency, and abuse prevention.
• Essential Cookies and Preferences: Local browser storage (localStorage) to store interface preferences (light/dark theme and active locale).

All data processing carried out by Datafindex rests upon legitimate legal grounds: (a) Express and unequivocal consent for support requests; (b) Controller legitimate interest for system integrity and mathematical optimization; and (c) Compliance with applicable statutory and regulatory obligations.

As a data subject, you hold inalienable statutory rights, exercisable free of charge at any time upon request:

• Confirmation of data processing existence and access to personal records.
• Correction of incomplete, inaccurate, or outdated data.
• Anonymization, blocking, or elimination of unnecessary or excessive data.
• Data portability to another service provider in standard machine-readable format.
• Revocation of previously granted consent and immediate deletion of related records.
• Information regarding public or private entities with whom data has been shared.

We implement state-of-the-art security safeguards: end-to-end TLS/HTTPS encryption, defensive security headers (HSTS, strict Content-Security-Policy, X-Content-Type-Options), runtime sandboxing, and automated PII masking in telemetry session recordings.

Datafindex never sells, rents, or monetizes personal data with third-party brokers or advertisers. Sharing is strictly confined to essential cloud infrastructure and runtime monitoring providers governed by binding confidentiality agreements.
