Key Disclosures
Double-check all critical output formats before production release.
Calculators run locally; server utilities like bg removal purge data within 24 hours.
Execution speed and capacity depend on your local hardware and browser.
1. General Information & Technical Accuracy
The utilities, formatters, calculators, encoders, and converters hosted on rana.com.bd are developed in good faith to assist daily engineering, drafting, and data preparation workflows. Approximately 90% of tools operate client-side in your local browser sandbox, while approximately 10% of specialized tools (such as background removal and social media tools like the facebook comment picker) utilize secure server-side processing subject to a 24-hour permanent deletion policy. While tools adhere to common industry standards, we make no representations or warranties regarding complete accuracy, completeness, or suitability for critical system deployments.
2. Client-Side Execution Variance
Because approximately 90% of tools run completely in-memory inside your local web browser engine, computational performance, regex matching timeouts, and float-precision calculations can vary based on:
- Browser JavaScript engines (e.g., Google Chrome V8 vs. Mozilla SpiderMonkey vs. Apple JavaScriptCore)
- Local device hardware memory allocations, CPU throttling, and available swap
- Installed third-party browser extensions, userscripts, or content blockers
Always independently verify results before committing critical data to production databases or automated deployment scripts.
3. Cryptography, Hashing & Security Warning
Tools generating hashes (such as MD5, SHA-256), UUIDs, JWT parsing, and Base64 translations utilize standard Web Crypto APIs and browser memory. These utilities are provided for testing, format verification, and development inspection. Legacy algorithms like MD5 are computationally vulnerable to collision attacks and should never be used as the sole integrity verification for high-security applications. For more details, visit rana.com.bd.
4. Financial & Tax Calculators
Our finance utilities (such as EMI, GST, VAT, Loan, and Tax calculators) provide indicative estimations based on mathematical formulas. They do not constitute formal financial, accounting, legal, or tax advice. National tax brackets, compound interest conventions, and local municipal laws fluctuate; always consult a certified accountant or financial advisor for binding tax filings.
5. Third-Party Links & External Platforms
Links pointing to external platforms (such as Lettermate, Age Calculator Live, or public code registries) are provided for convenience. We have no operational control over external websites and accept no responsibility for their content, policies, or server-side security standards.
6. Limitation of Liability
Under no circumstances shall RANA or Rana Bepari be held responsible or liable for any direct, indirect, consequential, or incidental loss or damage incurred as a consequence of relying on outputs generated by tools on this website.
