Small tools, measured properly

How it works

Each tool is one page that does one thing. There's no upload step and no processing queue: the page loads, and the tool runs on your machine.

Tools are added when they're useful, not to fill a grid. Every one is listed on the tools page.

Your data

• Tool input never leaves your device. Text you paste, PDFs you drop and numbers you type are processed in the browser. None of it is sent to a server.
• Your account is stored. Name, email and a hashed password, so you can log in. Passwords are hashed with PBKDF2 and are never stored or recoverable in plain text.
• Sessions are tracked. We record which browser and operating system a session was started from, so you can tell your own sessions apart.
• No analytics, no advertising, no third-party trackers.
• Some tools save locally. The task checklist keeps its list in your browser's local storage. Clearing browsing data removes it.

Accounts and sessions

Sign-up is by approval. New accounts are created inactive and an administrator activates them. Until then, logging in is blocked.

One device at a time. An account can hold exactly one live session. Logging in on a second device signs the first one out, and that device is told why rather than being silently bounced to the login page.

Sessions last seven days unless you log out, log in elsewhere, or an administrator ends them.

Getting help

Something broken or a tool you'd find useful? Tell the person who gave you your account — that's the fastest route to getting it fixed or built.
