Data and privacy requests

Sift provides export and deletion controls in the App:

  • Export contributed samples: Settings → Data & Privacy → Export all submissions.
  • Erase contributed samples: Settings → Data & Privacy → Erase all submitted data.
  • Withdraw anonymous-contribution consent: turn off the anonymous-contribution toggle in the App.

For anything that cannot be handled in the App, email support@alkinum.io and include “Sift” in the subject line.

Sift organizes messages on device and keeps the privacy boundary there.
