# Data storage

> SQLite, Keychain, sandbox, and data isolation

## Local SQLite

| Data type                           | Rebuildable?           |
| ----------------------------------- | ---------------------- |
| Repo metadata / README cache        | Yes                    |
| Tags / notes / status / collections | **No**                 |
| AI / RAG history                    | Back up if you need it |
| AI summary cache                    | Regeneratable          |

Stack: GRDB.swift + FTS5; schema upgrades through versioned migrations — production users should not delete the database.

## Keychain

* GitHub OAuth / PAT
* AI provider API keys
* Local integration secrets

## App Store vs Direct

Separate containers and directories — **data does not transfer automatically**. See [Installation](/getting-started/installation).

## Account isolation

Local data is isolated per GitHub account; switching accounts does not automatically wipe another account's data.

## Cloud sync

Not shipped yet. See [Backup](/data-privacy/backup).
