Cookie Policy

Last updated 16 October 2026

Slingdrop uses a small number of first-party cookies and browser storage that are needed for the service to work. We don't use advertising or cross-site tracking cookies.

Cookies we set

  • Session cookie (better-auth): keeps you signed in. Expires when you sign out or after inactivity.
  • Viewer cookie (sd_vid): a random identifier so senders see unique views rather than every page reload, and so we can rate-limit abuse. It isn't used across other sites.
  • Owner cookies (sd_o_…): let someone who sent a drop without an account manage it from the same browser. Kept for 90 days.
  • Access cookies: remember that you unlocked a passcode-protected or private drop. Short-lived and scoped to that drop.

Browser storage

Local storage and IndexedDB keep your theme choice, drops you sent from this device, and the encryption keys for your devices' inbox. Vault keys stay in the link and are never stored by us.

Third parties

We don't load third-party analytics or advertising scripts. Cloudflare may set cookies needed for security and bot protection.

Your choices

You can clear cookies and storage in your browser at any time. Blocking the session cookie will sign you out, and blocking the others will limit some features.
