Data retention and deletion
Retention is user-controlled, not time-based
Section titled “Retention is user-controlled, not time-based”The inspected application has no automatic time-based retention schedule for sessions, transcripts, summaries, local indexes, or settings. They remain in their respective local stores until you delete a session, reset app data, delete a model, remove an export, or otherwise remove the data.
What each action removes
Section titled “What each action removes”| Action | Removes | Does not remove |
|---|---|---|
| Delete one session | The session’s SQLite row, transcript, summary, and derived session and global search indexes. | The original imported source file, normalized WAV copies in the application audio directory, and exports. |
| Clear a summary | The persisted summary and its session-level summary embedding. | The transcript, session row, and any external-provider copy. |
| Reset app data | All session and index rows in SQLite plus Synthezia-prefixed webview local-storage settings and templates. | Normalized audio copies, downloaded models, user-owned import files, and user-selected exports. |
| Delete a model in Model Manager | The selected local Whisper model or local Ollama model when the operation succeeds. | Sessions, summaries, settings, audio, and external-provider data. |
| Development-only full installation reset | Session/index rows, Synthezia-prefixed storage, downloaded models, local audio copies, and Ollama runtime state. | Imported source files and files you exported to a chosen destination. |
The full installation reset is exposed only in the development UI. It is not a normal end-user deletion method.
Chat history and remote retention
Section titled “Chat history and remote retention”Per-session and global chat messages are held in frontend memory in the current flow. Reloading the application or clearing that frontend conversation removes those in-memory messages, while the transcript and summary source data remain in SQLite.
If External API is selected, a provider can retain data it received under its own policies. Local session deletion and app reset do not contact that provider or prove remote deletion.
Before using a deletion action
Section titled “Before using a deletion action”- Export or back up only the files you intend to keep; the database reset cannot be undone through Synthezia.
- Delete exports separately from the destination where you saved them.
- If normalized audio removal matters, treat the current ordinary deletion and reset-app-data flows as incomplete for that category.
