Total storage used —

policy

These tools respect your privacy. Nothing you do here leaves your browser.

  • All data stays on your device

    Transactions, flashcards, habits — everything is saved in your browser's local storage. No server ever sees it.

  • No tracking, no analytics

    No cookies, no analytics, no third-party trackers. Nothing about your usage is sent anywhere.

  • One peek at your browser, then nothing

    On first visit only, the site reads your browser's preferred language list and timezone in your own browser to pick English or Portuguese as the default. These signals are never sent to any server, never stored, and never used to identify you. You can change the language any time with the globe button.

  • No accounts required

    No sign-up, no email, no password. Just open a tool and start using it.

  • Export and import anytime

    Each tool lets you download a JSON backup of your data and restore it later — on the same device or any other one.

  • You can erase everything in one click

    Each tool has a Clear All Data option that wipes its local storage. Or just clear your browser data — there's nowhere else for it to live.

Data is tied to a single browser. Different browsers or devices won't see each other's data — use export/import to move between them.
