Does the password generator save my password anywhere?

No. It runs in your browser using the built-in Web Crypto API. The generated password exists only in the page memory until you close the tab. We have no record of it, and nothing is transmitted to our servers.

Why do word-count numbers differ from my word processor?

Word processors define "word" slightly differently — some split on hyphens, some do not; some count contractions as one word, some as two. The counter here uses the whitespace-split convention that most academic style guides (APA, MLA, Chicago) also use, but you may see 1-3% variation vs Word or Docs.

Do the time-zone conversions handle daylight-saving transitions?

Yes. The tool uses the IANA time-zone database (the same source that Linux, macOS, iOS and Android use), so daylight-saving transitions are correct historically and for future years within the database's current maintained window.

Productivity

Everyday time, text and unit tools — age calculation to the day, working-days-between-dates that subtracts your custom holiday list, time-zone stacking for scheduling meetings across three continents, a live word counter with reading-time estimate, a secure password generator that never touches our servers, and a universal unit converter covering ten measurement systems.

About productivity on Dailiyo

Productivity tools are the tools you did not realise you needed until you did. A GPA weighted correctly across credits. A leave counter that excludes weekends and your team's public holidays. A Roman-numeral converter that handles the "IIII vs IV" distinction most clock-faces use. A colour converter that round-trips between HEX, RGB and HSL without losing precision. These are small utilities that individually save seconds but collectively save hours across a working month.

Where our productivity tools differ from most calculator sites is transparency about what runs where. The password generator uses the browser's built-in crypto.getRandomValues() — your generated password never leaves your device and is not logged anywhere. The word counter runs entirely client-side, so pasting a confidential draft does not send it to any server. The time-zone tool uses the standard IANA tz database that every operating system uses, so daylight-saving transitions are handled correctly for every year.

The unit converter deliberately handles the categories that OS-level calculators do not: not just length and weight but data (KB/MB/GB with both decimal and binary interpretations), pressure, energy, and time. Where a category has cultural variation — recipe cups (US customary vs metric), land area (katha vs decimal vs acre), calendar systems (Gregorian, Hijri, Bengali) — we cover both and label which is which so you do not accidentally scale a recipe from the wrong measurement standard.
