Your financial data stays on this device by default

Where your data lives

• Your income, expenses, savings, debt and life choices live only in your browser’s localStorage (two separate keys: real plan and simulation). Signed out, this data never leaves the device.
• After sign-in (optional): your email is used for Supabase Auth; your local plan draft syncs to a cloud plans table as backup and cross-device copy. Row-level security means only your account can read or write your rows.

What we measure

• Cloudflare Web Analytics: page views and visits. No cookies, no cross-site tracking.
• Our own event collector stores only event names and timestamps (e.g. “a calculation completed”). No IP, no user agent, no identifiers, and none of the numbers you enter.

What we never do

• We never sell or share your data with third parties for marketing.
• Your financial inputs are never used for model training, profiling, or ads.
• Signed out, none of your financial inputs are sent to any server.

Deletion

• Local data: clear your browser’s site data and it is gone immediately.
• Cloud copy: signing out only stops syncing and does not delete cloud data. To delete your account and cloud copies, contact us below and we will delete them.
