At a Glance: Core Privacy Architecture
100% In-Browser Execution
All number generation algorithms execute entirely inside your device's web browser using JavaScript. No telephone numbers or parameters are ever sent to our servers.
No Account or Personal Info
We never ask for your name, email, credit card, or telephone number. You can use all 79 tools completely anonymously without registration.
GDPR & CCPA by Design
Because we collect zero personal data, our platform is inherently compliant with global data privacy frameworks including EU GDPR and California CCPA.
SECTION 01DATA PRIVACY RULE
01. Zero-Knowledge Architecture
Our platform operates under a strict Zero-Knowledge paradigm. All calculations, regex validations, prefix lookups, and batch exports run locally in client-side memory.
When you generate single numbers or export 5,000 records, the computation happens directly in your browser. Our web servers serve only static HTML, CSS, and JS bundles.
SECTION 02DATA PRIVACY RULE
02. Absolute Data Exclusions
We explicitly DO NOT collect, store, or process: Personal Identifiers (names, emails, physical addresses), IP Address mapping logs, Financial Information, or User-submitted test values.
All exported files (CSV, JSON, vCard) are compiled via client-side Blob URLs and downloaded directly from local RAM.
SECTION 03DATA PRIVACY RULE
03. Local Browser Storage
The Service uses HTML5 localStorage solely for non-identifiable user interface preferences: 'numgen_theme' (storing dark/light mode preference) and 'numgen_lang' (storing chosen locale).
No tracking identifiers, analytics cookies, or cross-site fingerprinting tokens are written to local storage.
SECTION 04DATA PRIVACY RULE
04. Third-Party & CDN Services
We do not use invasive third-party analytics trackers, advertising pixels, or behavior monitoring scripts.
Static assets are served via high-performance, security-hardened Content Delivery Networks (CDNs) under strict HTTPS encryption.
SECTION 05DATA PRIVACY RULE
05. International Compliance (GDPR & CCPA)
Under the EU General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA), individuals have rights regarding personal information.
Because Random Mobile Number does not collect personal data, there is no personal database to inspect, export, or delete.
