Privacy Policy &
Data Protection Architecture
Your personal compensation figures, bonus details, and tax deductions are private. Salary After Tax is engineered around a memory-only calculation pipeline: all take-home computations execute ephemerally, leaving zero records in our database and zero profile associations.
1. Information We Do Not Collect
Salary After Tax is designed intentionally as an open, privacy-preserving utility. Unlike traditional financial websites, we do not require you to create an account, log in, or disclose your identity.
We do not store, record, or profile:
- Your Salary or Income Figures: Any amount typed into the gross or net fields exists only in your browser session or in temporary server RAM during the calculation lifecycle.
- Your Tax Deductions & Exemptions: Bonus figures, retirement contributions, healthcare deductions, and marital statuses are never linked to any database profile.
- Personally Identifiable Information (PII): We do not ask for your legal name, physical address, Social Security Number (SSN), National Insurance Number, or financial institution logins.
2. Ephemeral In-Memory Calculation Architecture
When you submit an input on our calculators (via instant client-side JavaScript or our high-speed REST calculation endpoints), variables are passed over encrypted Transport Layer Security (TLS 1.3). The tax calculation engine applies statutory progressive brackets, computes allowances, returns the numerical result, and immediately purges the payload from active memory.
Our backend does not write calculation history to relational database tables, cache files, or log registries.
3. Technical Server Logs & Security Monitoring
To maintain server uptime, protect against automated denial-of-service (DDoS) attacks, and enforce rate limits on our calculation APIs, our web servers collect standard, automated technical request headers:
- Internet Protocol (IP) address (temporarily logged for rate-limiting and firewall filtering)
- Browser type, operating system, and user-agent string
- Referring page and requested site resource URL
- HTTP response status code and execution timestamp
These diagnostic logs are retained temporarily for security operations and automatically purged on a rolling schedule. They are never merged or cross-referenced with your calculation values.
4. Cookies and Local Storage
Salary After Tax uses minimal, strictly functional cookies and HTML5 local storage:
You can configure your browser to reject cookies or clear local storage at any time; all calculators will continue to function normally without restriction.
5. International User Rights (GDPR & CCPA/CPRA)
Regardless of your jurisdiction, Salary After Tax honors fundamental global privacy principles. Under the General Data Protection Regulation (EU/UK GDPR) and the California Consumer Privacy Act (CCPA/CPRA):
- Right to Know / Access: Because we do not store identifying user records or financial numbers, we hold no personal data profile tied to your identity.
- Right to Deletion: Any local preferences stored in your browser can be cleared immediately through your browser's history and cookie settings.
- Do Not Sell or Share My Personal Information: We do not sell, rent, or trade user data to third-party data brokers or behavioral advertisers.
