Open tool →About these everyday & fun
Every tool below is free, works in your browser, and needs no account.
- Where is my habit data saved?
- In your browser's local storage — your streaks survive refreshes, and nothing is uploaded anywhere.
- Is the love calculator serious?
- Not even slightly. It's a deterministic hash of two names, framed honestly as for-fun.
- Does the screen recorder upload my recording?
- No — recording and download happen entirely on your device via the MediaRecorder API.
