Security

OysterCatcher is built as a privacy-first macOS utility. Scans run locally on your device. No cloud uploads.

  • Local-only scanning by default.
  • Optional online token validation (off by default).
  • Designed for data minimisation: scan findings are stored as lightweight metadata; sensitive snippets are not persisted.
  • Retention controls: ignore, Trash, or schedule deletion to reduce accidental retention over time.
  • Clear actions: Ignore, Trash, Remind later.
  • Supports data minimisation principles.

We do not claim certifications we cannot prove.
