CurTiPen

About

CurTiPen (stands for Currency, Timezone and Percentage calculator) adds a small, movable widget on top of any white-listed website. It puts three everyday tools in one place so you don't have to switch tabs: a currency converter, a percentage calculator, and a world-clock / timezone converter. It's built with customer support agents and accountants in mind, but it works wherever you browse. It's for desktop browsers only, and there's no account or sign-up needed. No data will be sent, privacy and data security is key.

Key features:

- Convert between around 40 world currencies using up-to-date exchange rates
- Also convert from 18 popular cryptocurrencies (Bitcoin, Ethereum, and more) into regular money
- Show a second currency at the same time, such as your own local currency
- Swap the input and output currencies with one click
- A percentage calculator for quick "X% of Y" and "what percent is A of B" math
- See the same date and time in your own timezone and someone else's
- The widget can guess the currency and the other person's timezone from the page you're on (not guaranteed to work, depending on the layout of the page)
- Select a time (mark with your mouse) on the page and have the time field fill in for you
- Drag the widget anywhere; it gently snaps (optional) to the edges of the screen
- Buttons to lock it in place, shrink it, hide it on a site, refresh, or close it
- You choose which websites it appears on, one by one
- Optional mode to show it on every website by default
- A "never show here" (blacklist that can be edited) list that always takes priority
- Sliders for transparency, text size, and overall widget size
- Dark, light, and custom color themes (pick your own three colors)
- Show or hide each section (currency, percentage, time) on its own
- Copy buttons to copy just the number or the full amount with currency symbol or 3-letter
- Choose how often the currency exchange rates refresh, from every 10 seconds to once a day
- A "Boost" mode for extremely slow computers or remote-desktop sessions
- Find your own timezone and currency automatically, with no location tracking (taken from your computer settings)
- A live preview in the settings page, so you see changes as you make them
- No account, no sign-up, and nothing you type is sent anywhere
- Your settings sync across your signed-in browsers (requires google account and sync turned on)
