🔒 Privacy Policy
Effective Date: January 1, 2026
Last Updated: September 27, 2026
Welcome to calpp.io ("the Website", "We", "Us", or "Our"). This Privacy Policy transparently outlines our principles, practices, and policies regarding data collection, client-side calculator execution, analytics, third-party advertising, and your statutory rights under the European Union General Data Protection Regulation (GDPR), the California Consumer Privacy Act (CCPA/CPRA), Brazil's Lei Geral de Proteção de Dados (LGPD), and international privacy frameworks.
1. Client-Side Financial Calculation & Zero-Data Storage
Your financial privacy is our highest priority. When you input numbers into any of our calculators (such as commercial amounts, percentages, fixed fees, donation values, or mass payment batches):
- All mathematical formulas and fee calculations are executed exclusively within your local web browser via client-side JavaScript.
- We do not record, transmit, inspect, or store the amounts you calculate, your gross income, transactional volume, customer identifiers, or financial estimates on any server.
- We never request, collect, or store your banking credentials, credit card details, or PayPal account passwords. We have no access to your personal financial records or PayPal account balance.
2. Data We May Collect Automatically (Usage & Telemetry)
When you visit calpp.io, our web servers and standard analytics tools may collect non-personally identifiable diagnostic and telemetry data, including:
- Device and Browser Information: Browser type, operating system version, screen resolution, and language preferences.
- Diagnostic Server Logs: Internet Protocol (IP) address (anonymized/truncated where required by law), timestamps of requests, referring URLs, and resource latency.
- Aggregated Engagement Metrics: Pages viewed, time spent per session, and regional selector interactions, used solely to maintain uptime, prevent denial-of-service attacks, and improve tool responsiveness.
3. Cookies and Web Storage
calpp.io uses minimal cookies and browser local storage mechanisms:
- Functional Local Storage: May be used strictly to remember your preferred currency or interface settings across sessions without identifying you personally.
- Analytics & Performance Cookies: Used to understand general traffic volume and detect technical errors.
- Advertising Partners: We may work with reputable contextual advertising networks (such as Google AdSense) to keep our calculators free of charge. Advertising partners may use cookies to serve non-intrusive, relevant advertisements in accordance with industry privacy standards. You may opt out of personalized advertising by visiting AboutAds.info or Google Ads Settings.
4. European Privacy Rights (GDPR / UK GDPR)
If you are an individual residing in the European Economic Area (EEA) or the United Kingdom, you have rights under the General Data Protection Regulation, including:
- Right of Access: Request confirmation as to whether personal data is processed and receive a copy.
- Right to Rectification: Request correction of inaccurate or incomplete personal information.
- Right to Erasure ("Right to be Forgotten"): Request deletion of your personal data where retention is no longer justified.
- Right to Restrict or Object: Restrict or object to the processing of your data under specific statutory conditions.
- Right to Lodge a Complaint: Lodge a complaint with your local Data Protection Supervisory Authority (such as the AEPD in Spain, CNIL in France, BfDI in Germany, or the Garante in Italy).
5. California Consumer Privacy Rights (CCPA / CPRA)
Under the California Consumer Privacy Act and California Privacy Rights Act, California residents enjoy specific rights:
- No Sale of Personal Information: calpp.io does not sell, rent, or trade your personal information or transaction history to third parties for monetary or other valuable consideration.
- Right to Know and Delete: You have the right to request disclosure of categories of personal information collected and request deletion.
- Non-Discrimination: We will never discriminate against you, deny services, or provide a different quality of service for exercising your privacy rights.
6. Brazilian General Data Protection Act (LGPD)
In accordance with Brazil's Lei Geral de Proteção de Dados (Lei nº 13.709/2018), users in Brazil have the right to obtain confirmation of the existence of data processing, access to data, anonymization or blocking of unnecessary data, and revocation of consent at any time.
7. Third-Party Links & Non-Affiliation
Our website contains informational links to external resources, including official fee schedules on paypal.com. calpp.io is an independent analytical tool and is not affiliated, endorsed, or partnered with PayPal Holdings, Inc. Once you navigate away from calpp.io, external websites operate under their own independent privacy notices, which we encourage you to review.
8. Data Security & Retention
We deploy standard security measures, including end-to-end TLS/HTTPS encryption, secure server configurations, and strict Content Security Policies to protect data in transit. Server access logs are routinely purged and retained only for security audit compliance.
9. Updates to This Policy
We may update this Privacy Policy periodically to reflect technological changes, regulatory requirements, or website enhancements. The "Last Updated" date at the top of this document indicates when modifications took effect.
