Schplitz — Privacy-First Expense Splitting
Split expenses with your partner or travel companion. No account, no server, no cloud. Your data is encrypted with AES-256-GCM and stays on your device.
How it works
- Set a shared secret — Pick a security question only you two would know. The answer is the encryption key; we never see it.
- Log your expenses — Add what you spent. Everything stays on your device. Nothing is transmitted without your action.
- Share an encrypted link — Your expenses are encrypted before they touch the URL. The other person decrypts with the same answer.
- See who owes what — Schplitz calculates the balance across currencies at the historical exchange rate. No account required.
