Privacy Policy & Zero-Telemetry Guarantee

1. Core Philosophy: Client-Side Sandbox

RANA Web Utilities are built upon an unambiguous technical premise: Zero Data Ingestion. Approximately 90% of tools on rana.com.bd (including JSON parsers, formatters, Base64 transformers, hash engines, and regex suites) execute purely in-memory inside your local web browser's JavaScript V8/SpiderMonkey engine.

Your input payloads, files, query parameters, and generated tokens are never dispatched to our origin servers, proxy nodes, or any third-party computing infrastructure.

2. Specialized Server-Side Processing (10%)

While 90% of tools execute client-side, approximately 10% of specialized utilities—such as background removal (remove bg) and social media tools like the facebook comment picker—require secure server-side execution to interface with AI vision models or third-party graph APIs.

For these specific tools, uploaded assets or data are processed securely on our infrastructure and are subject to a strict 24-hour permanent deletion policy, ensuring no long-term retention of user media or comment history.

3. Zero Network Telemetry & Payload Tracking

When you transform sensitive data (such as API keys, environment variables, JWTs, SQL schemas, or code repositories), the computation remains entirely offline-capable after the initial static asset download.

• No HTTP POST payloads containing raw input bodies for client-side tools
• No automated remote crash logging for inputs or outputs
• No behavioral screen recordings or cursor heatmaps
• No external tracking beacons or advertising identity cross-matching

4. Local State & Ephemeral Storage

Any state preservation—such as remembering active theme preferences, category view selections, or quick scratchpad settings—lives exclusively within your browser's native localStorage or sessionStorage. This data remains on your physical disk and can be purged instantly by clearing browser cache.

5. Edge Distribution & Transient Network Logs

Our static application assets (HTML, CSS, compiled JavaScript bundles, and WebAssembly modules) are cached and delivered via high-speed global edge CDNs. Like any web distribution node, the edge server may process standard ephemeral network protocol headers (such as IP address, requesting browser user-agent, and requested static file path) solely to deliver assets, prevent distributed denial-of-service (DDoS) attempts, and fulfill technical TLS handshakes.

6. External Ecosystem & Third-Party Platforms

Our site contains direct links to our sister platforms (e.g., Lettermate, Age Calculator Live, eMoney Tracker) and external documentation sources. When you click an external link, you navigate outside the RANA domain boundary, and that respective destination's privacy policy dictates their terms. For help and resources, visit rana.com.bd.

7. Security & Inquiries

If you have questions regarding the underlying client-side security architecture or wish to submit an audit report, direct inquiries may be sent to [email protected].
