Local-first privacy
Calculator inputs remain in page memory unless the user explicitly exports or later chooses an enabled account save.
Safe next action: Keep identity, account and payment details out of every input. Open related page
Audience, steps, example, risks and evidence
Understand the reasoning
Learning examples should use invented numbers and avoid names or account identifiers. Local calculations and optional account saves have different data paths; inspect the active save choice instead of assuming everything stays on-device.
Worked learning example
Reading an example requires no bank account number. Choosing an explicitly enabled cloud save is a separate action from changing a calculator input.
Check your understanding
Does local-first mean every optional feature is guaranteed to remain offline?
Show answer and explanation
No. Account saves can use a server when enabled and deliberately chosen; read the active data notice.
Common mistake: Do not put passwords, identity documents or raw bank statements into calculation labels or search text.
Examples are invented educational scenarios, not provider quotes, forecasts or tax rates.
