GDPR Notice

Effective: 2025-08-22

+ +

Controller

+

The operator of this shard acts as data controller. Contact: dsapelli@yahoo.com.

+ +

Lawful bases

+
    +
  • Public posts: performance of service you request.
    • +
  • Private posts: performance of service; encryption keys never leave your device.
    • +
  • SSO (optional): your consent with the chosen provider.
    • +
+ +

Minimization & storage

+

No user profile, no behavioral analytics. Objects are stored by content hash; server logs are minimized and scrubbed of IPs/UA where feasible.

+ +

International transfers

+

Content may be hosted where you deploy the shard. Using third-party SSO may transfer data to those providers’ regions.

+ +

Data subject rights

+

Access/erasure/rectification: We do not keep a server-side identity. Uploaders can delete objects by hash if they still possess authorization. Encrypted content cannot be decrypted server-side.

+ +

Complaints

+

You may lodge a complaint with your local supervisory authority.
