Privacy Policy

1. What we collect

Account data: email address and display name if you create an account; OAuth identifiers if you sign in with Google or Apple. Inputs you voluntarily enter into calculators, and conversation text sent to the AI assistant.

Technical data: basic request logs and aggregated usage metrics used to operate and secure the Service.

2. What we never ask for

We never request bank passwords, full payment-card numbers, transaction passwords, government ID copies, or account login credentials. Do not provide them in calculator fields or chats.

3. How data is used

To operate calculators and the AI assistant, save your history while logged in, process subscriptions, prevent abuse, and improve educational content. We do not sell your personal data.

4. Processors

Payments are handled by Creem.io; sign-in may use Google or Apple; infrastructure runs on Cloudflare. These providers receive only the data needed for their function under their own privacy terms.

5. Cookies and local storage

We use essential cookies for authentication and preferences (such as theme and language), and local storage to remember guest sessions and quota counters.

6. Your choices

You may use the Service as a guest, delete account data on request, and clear local storage in your browser at any time.
