Privacy Policy

Your conversations belong to you. We've designed Kursal so literally no one can access your messages.

Our Commitment

Kursal is built with privacy as its foundation. We believe your conversations belong to you, and we've designed our system to ensure we literally cannot access your messages.

Data We Don't Collect

Because the Kursal app is peer-to-peer and fully decentralized and we do not want to invade your privacy:

No access to encryption keys
No analytics or usage tracking
No conversation metadata

Data Peers Could Collect

Your encrypted messages go through public relays. Those relays can track some limited informations about you:

Your IP address (can be changed with a VPN)
When you send messages
Your Peer ID and the destination Peer ID (which periodically rotates and makes the 'when' harder to track)

How Kursal Works

All encryption happens locally on your device. Messages are transmitted directly between peers using end-to-end encryption. There is no central server that processes or stores your communications. Even if your messages transit through public relays, no one but the receiver can decrypt them.

Website Data

This website does not use cookies but tracks the number of visitors using Plausible, a privacy-friendly tracking platform (which will be self-hosted in a near future).

If you sign up for our mailing list, your email is stored solely for the purpose of sending you updates. It is self-hosted and stored in Germany. You can unsubscribe at any time via the confirmation email. We will never distribute or sell your email! If you can't find the unsubscription link or need assistance, you can always reach us on our email for help.

Open Source

Kursal is fully open source. You can audit our code at any time to verify our privacy claims. We encourage security researchers to review our implementation.

This privacy policy is intentionally simple because our approach to privacy is simple: we don't collect your data because we can't. That's how Kursal is designed.
