When you record or track PayPal transactions, your configured PayPal API keys are used to communicate directly with PayPal’s API servers. No data is transmitted to PayPal except when explicitly initiated by the site administrator during PayPal API configuration or transaction processing. * **PayPal**: https://paypal.com * **PayPal Privacy Policy**: https://paypal.com/privacy * **PayPal Terms of Service**: https://paypal.com/legal ### Third-Party Libraries All libraries run entirely on your server and do not connect to external services. * **mPDF** — PDF invoice generation - License: GPL-2.0-or-later - Source: https://github.com/mpdf/mpdf * **psr/log** — PSR-3 logger interface (used by mPDF) - License: MIT - Source: https://github.com/php-fig/log * **myclabs/deep-copy** — Object deep cloning (used by mPDF) - License: MIT - Source: https://github.com/myclabs/DeepCopy * **setasign/fpdi** — PDF template import (used by mPDF) - License: MIT - Source: https://github.com/Setasign/FPDI * **paragonie/random_compat** — `random_bytes` polyfill (used by mPDF) - License: MIT - Source: https://github.com/paragonie/random_compat ### Privacy Zoventic Invoices stores the following data exclusively in your WordPress database. Nothing is sent to external servers except when explicitly using the PayPal payment integration. * **Client records** — Name, email, phone, address, and notes entered by the administrator. * **Invoice and payment records** — All billing data entered by the administrator. * **Activity log** — Records of administrative actions including the IP address of the logged-in administrator performing each action. IP addresses are stored for audit purposes only and are not shared externally. To comply with privacy regulations (e.g. GDPR), site administrators are responsible for obtaining appropriate consent from their clients before entering their personal data into the plugin. For data erasure requests, all Zoventic Invoices data can be permanently removed by deleting the plugin via the WordPress admin, which will drop all plugin database tables and options. ### Advanced Configuration #### Trusted Proxy IPs (X-Forwarded-For) If your WordPress site runs behind a load balancer or reverse proxy, the activity log may record the proxy’s IP address instead of the real visitor IP. To enable X-Forwarded-For header trust for specific proxy IPs, add the following to your ` wp-config.php`: define( ‘ZINV_TRUSTED_PROXIES’, [ ‘10.0.0.1’, ‘10.0.0.2’ ] ); Replace the example IPs with your actual proxy server IP address(es). **Only add IPs that you fully trust** — enabling this for an untrusted IP allows clients to spoof their IP address in log entries. ## Screenshots [⌊Dashboard — KPI overview, revenue chart, activity feed, and pending transactions⌉⌊ Dashboard — KPI overview, revenue chart, activity feed, and pending transactions⌉[ Dashboard — KPI overview, revenue chart, activity feed, and pending transactions [⌊Invoice Builder — Line items editor, client selector, tax and discount controls, live PDF preview⌉⌊Invoice Builder — Line items editor, client selector, tax and discount controls, live PDF preview⌉[ Invoice Builder — Line items editor, client selector, tax and discount controls, live PDF preview [⌊Client Directory — Account type badges, lifetime value tracking, CSV import⌉⌊Client Directory — Account type badges, lifetime value tracking, CSV import⌉[ Client Directory — Account type badges, lifetime value tracking, CSV import [⌊Payments — Transaction history with method icons and status pills⌉⌊Payments — Transaction history with method icons and status pills⌉[ Payments — Transaction history with method icons and status pills [⌊Settings — Company profile, PayPal integration, and invoicing preferences⌉⌊Settings— Company profile, PayPal integration, and invoicing preferences⌉[ Settings — Company profile, PayPal integration, and invoicing preferences [[ ## Installation 1.
