Frequently Asked Questions

Are all tools completely free?

Yes — every tool on BanglaiBlog Tools is 100% free, forever. No premium plan, no subscription, no hidden fees. We believe useful tools should be accessible to everyone.

How accurate are the prayer times?

Prayer times are calculated using the Aladhan.com API, which uses your city's exact latitude and longitude with astronomical formulas. You can choose from 13 calculation methods including ISNA, MWL, Umm Al-Qura, and more. Times are recalculated fresh every day.

How often are currency rates updated?

Exchange rates are fetched from the Open Exchange Rates API and updated every 24 hours automatically. Rates are also cached in your browser so the tool works even with a slow connection. The rates shown are mid-market rates — the actual bank rate you get may differ slightly.

Do you collect any personal data?

We collect only what you voluntarily provide — your name and email if you subscribe to our newsletter, or contact form submissions. We do not use tracking cookies, do not sell data, and do not require any account to use the tools. Read our full Privacy Policy for details.

Can I suggest a new tool?

Absolutely! We add new tools regularly based on community suggestions. Use our Contact page and select "New Tool Suggestion". We read every message and reply within 48 hours.

Why these tools are different

BanglaiBlog Tools is built around practical tasks rather than a collection of thin pages. Each tool has a clear purpose, an explanation of how its result is produced and a note about important limitations. Many utilities run locally in the browser so simple transformations do not need a server.

Fast by design

Pages use lightweight HTML, CSS and JavaScript, with no required account and minimal third-party dependencies.

Clear assumptions

Calculators explain what their numbers mean so you can tell an estimate from a guaranteed real-world value.

Privacy-conscious

Browser-based tools are designed to keep ordinary inputs on your device whenever a server is not needed.

How to choose the right tool

For money questions, start with the finance calculators and read the assumptions before using a result for a real decision. For writing or development work, the data and text tools handle common formatting and conversion tasks. Global tools cover exchange rates, prayer times, tipping and international transfers. If you are unsure which page fits your task, use the search box above.

We also publish practical explanations in the Blog and document our testing approach on the Methodology & Editorial Standards page.

Frequently asked questions

Are the tools free?

Yes. The collection is designed to be usable without a paid account.

Do I need to install anything?

No. Supported tools run in a modern web browser.

Are calculator results financial advice?

No. Financial tools are estimates based on the inputs and assumptions shown on the page. Use official documents and qualified professionals for consequential decisions.

How can I report a problem?
