What Kontu is
Kontu is a personal finance tracking tool. You enter your account balances, debts, income, recurring costs, receivables, and savings goals. We store that data so you can plan your month and track your net worth over time. We do not connect to your bank or process real financial transactions.
What we collect
- Account info — your email address and, optionally, a display name and profile photo.
- Financial data you enter — account and debt balances, planned income and costs, receivables, savings goals, and check-in history. This is data you type in manually.
- Usage data — basic logs generated by our hosting provider (Vercel) and database provider (Supabase). We do not use analytics trackers.
How we use your data
Solely to operate the app for you. Your financial data is used to display your net worth, chart your history, and surface upcoming payments. We do not sell your data, share it with advertisers, or use it for any purpose other than running Kontu.
Where data is stored
Your data is stored in a PostgreSQL database hosted by Supabase. Each user's data is isolated using row-level security — only you can read or write your own records. If you upload a profile photo, its file URL is publicly accessible, although Kontu does not publish a user directory or show your profile to other users.
Sign in with Google
If you sign in with Google, we receive your email address and display name from Google. We do not receive access to your Google account, Gmail, Drive, or any other Google services.
Deleting your data
You can delete all your financial data or your entire account at any time from Settings → Danger zone. Deleting your account permanently removes everything we hold about you.
