Privacy & Background Activity

True Recall is local-first. No telemetry, analytics, or background data transmission.

Periodic timers (setInterval) — all local, no network:

  • Database safety-flush — writes pending changes to the local SQLite file in your vault.
  • Optional background backup — writes a backup file inside your vault when enabled in settings.
  • Device-lock heartbeat — updates a small lock file inside your vault to prevent two Obsidian Sync clients from corrupting the database when both are open. Local file write only.
  • UI status polling — reads in-memory state to refresh diagnostics/backup panels.

Network requests — only on explicit user action or one-time per release:

  • Update check — when the plugin version differs from the last seen version, a single requestUrl call is made to the GitHub Releases API to fetch release notes. Runs once per version, not on a timer.
  • AI / RAG features (opt-in) — flashcard generation, semantic grading, and RAG are disabled by default. When enabled, requests go only to the LLM provider you configure (OpenRouter, your local Ollama, etc.). No third-party server is involved.
  • Local API server (desktop, opt-in) — binds to 127.0.0.1 only, used by the optional companion CLI. Never reaches the public network and is disabled by default.

Storage: All flashcards and review data live in .true-recall/true-recall.db inside your vault. Backups and lock files live in the same .true-recall/ folder. Nothing is uploaded anywhere.
