Where is it saved?
Your scratch pad is saved automatically in this browser on this device and is still there when you close the tab and come back — no account, nothing uploaded. Because it lives only here, it does not sync to your other devices and is erased if you clear your browsing data. Use Back up (.json) now and then, or download a Word, Excel or PDF copy.
Frequently asked questions
Can I download it as Word, Excel or PDF?
Yes — the Word button saves a .docx file, Excel saves an .xlsx spreadsheet and PDF saves a printable document. All three are created in your browser.
Is my scratch pad private?
Yes. It never leaves your device. Anyone using this same browser profile could open the page, so use a private profile on shared computers.
What maths can it do?
Anything the scientific calculator can: brackets, powers (^), roots (sqrt, √), percentages (%), trig in degrees, logs, factorials and π.
