Summary: OSHI is designed to collect zero personal data. All communications are end-to-end encrypted. We cannot read your messages, and we have no data to share with anyone.
This Privacy Policy explains how OSHI ("App", "Service", "we", "us", "our"), developed by Hugo Moriceau / Moriceau Lab, handles information when you use our application.
OSHI was built with privacy as a fundamental design principle. Unlike traditional messaging apps, OSHI's architecture makes data collection technically impossible.

OSHI stores the following data only on your device:
This data is stored in encrypted form on your device and never transmitted to us. If you delete the app, this data is permanently deleted.
All communications in OSHI are protected by end-to-end encryption:
This means:
When users are nearby, messages travel directly between devices via Bluetooth/WiFi. No servers are involved, and no data passes through our infrastructure.
When recipients are not nearby:
For voice calls when users are not on the same mesh network:
OSHI uses the following third-party services:
Purpose: Decentralized storage for encrypted messages. Data shared: Only encrypted blobs (unreadable without keys).
Purpose: App distribution. Data shared: Standard App Store analytics (anonymous, aggregated).
We do NOT use:
We do not share any data because we do not have any data to share.
In response to legal requests:
Under GDPR, Swiss DPA, and other privacy laws, you have rights including:
OSHI is not intended for users under 18 years of age. We do not knowingly collect any information from children. Since we collect no data, we have no way to verify ages or delete children's data.
Since we don't collect personal data, there are no international data transfers to disclose. Encrypted messages stored on IPFS may be distributed globally, but this data is encrypted and cannot be read by anyone except the intended recipient.
We protect your privacy through technical architecture:
Note: The App has not undergone a third-party security audit. While we use industry-standard encryption, we cannot guarantee absolute security.
We may update this Privacy Policy from time to time. Changes will be posted on this page with an updated "Last updated" date. Material changes may be notified through the App.
Our core commitment to zero data collection will never change.
Since we do not process personal data, no legal basis is required. The minimal technical data processed during message relay is:
Given our zero-data architecture, we have not appointed a formal DPO. For privacy inquiries, contact:
