Who we are
Hi2link is a mobile app that enables real-life encounters and information exchange between nearby people using Bluetooth Low Energy (BLE).
Contact: support@hi2link.com
Data we process
- Account & profile: an anonymous userID generated by the app (no personal info required at sign-up), display name or nickname, optional profile photo.
- Proximity & encounters: nearby BLE detections (ephemeral identifiers), timestamps, and exchange status.
- Location:
- Precise: used for your encounters history. This information is stored on your device only and is never transmitted to our servers.
- Approximate: sent to our servers for aggregate statistics (e.g., city/region, usage frequency). It is not linked to an identifiable user.
- Diagnostics: technical logs (crashes, performance), device model, OS version, and app version.
Purposes
- Provide core features (BLE detection, matching, business/personal cards, local encounters history).
- Improve the app through aggregated/anonymized statistics and diagnostics.
- Security, abuse prevention, and legal compliance.
Sharing
We do not sell data. Some information may be processed by technical processors (hosting within the EU). No data is used for advertising purposes.
Retention
- On device: history (including precise location) remains local until you delete it in the app or uninstall it.
- Server-side: aggregated statistics and diagnostics are retained for as long as necessary and then deleted or irreversibly anonymized.
Transparency & control
The service does not maintain a personally identifying profile on the server. Collected statistics are aggregated and are not attributable to a specific user. Therefore, individual deletion on the server is not applicable.
- Local history: you can clear it within the app (or by uninstalling), which removes precise location stored on the device.
- Server statistics: not tied to a userID → no per-user deletion. You can request assistance at support@hi2link.com.
Security
Communications with our servers are encrypted (HTTPS). BLE matching occurs on-device; no detection data is sent to our servers. Cards and profile conditions are stored on-device; sharing occurs only if you explicitly choose to share (e.g., via QR) or publish public info.
Legal basis (EU/GDPR)
Performance of the service (app functionality), legitimate interests (basic usage measurement and security), and where applicable your consent for sensitive permissions (e.g., location).
Children
Hi2link is not directed to children and is not intended for users under 13.
