Privacy Policy
Last updated: February 22, 2026
Overview
SecureShare is an open-source, peer-to-peer file sharing application designed with privacy as a core principle. We collect the absolute minimum data necessary to operate the service.
What We Do NOT Collect
- File contents — all transfers are end-to-end encrypted. The relay server never sees your data.
- File names or metadata — not logged, not stored.
- Session codes — not logged on the server.
- User accounts — there are none. No registration, no login.
- Cookies or tracking pixels — we don't use any.
- IP addresses in logs — IPs are only used in-memory for rate limiting and are never written to disk.
What We Collect
We collect anonymous, aggregated statistics to understand how the service is used and to improve it:
- Relay statistics: total number of sessions, bytes relayed, session durations (aggregated, not per-user).
- App version & OS type: to know which platforms need support.
- Crash reports: when the app crashes, an anonymous report (error type, traceback, app version, OS) may be sent automatically. No personal data is included.
- Landing page analytics: page views, referrer domains (not full URLs), selected language, screen size bucket (mobile/tablet/desktop). Unique visitors are counted using a SHA-256 hash of IP + daily rotating salt — the hash is not reversible and changes every day.
Data Storage
- All analytics data is stored on our self-hosted server (Oracle Cloud, Frankfurt region).
- No data is shared with third parties.
- No external analytics services (Google Analytics, etc.) are used.
- JSONL log files are rotated monthly and limited in size.
Downloads
Application downloads are served through GitHub Releases. GitHub's own privacy policy applies to the download process. We track download counts anonymously on our landing page via JavaScript beacons.
End-to-End Encryption
All file transfers use XChaCha20-Poly1305 encryption with keys derived from X25519 key exchange. The relay server acts only as a dumb pipe — it cannot decrypt, inspect, or modify any transferred data.
Open Source
SecureShare is fully open source. You can audit the code, verify our privacy claims, and build the application yourself:
