Categories are how you group your transactions. The Categories page shows every category you can use: the ones you create yourself, plus the ones synced from your banks. Finta, your [rules](/your-data/rules), and the [API](/api/v2/overview) and [MCP](/mcp/overview) all assign these categories to transactions. Categories live under **Your data** in the sidebar and require [storage mode](/getting-started/storage-mode). The Categories page showing a table of categories with their group and transaction count ## Create a category 1. Go to **Your data → Categories** and click **New category**. 2. Enter a name, and an optional group to keep related categories together. 3. Click **Create**. The New category dialog with a name and optional group ## Rename a category Open a category's menu and choose **Rename**. You can rename any category, including ones synced from your bank. The Rename category dialog for a bank-synced category When you rename a bank-synced category, your name sticks. Future syncs won't overwrite it with the bank's original name. ## Delete a category You can delete categories you created. Open the category's menu and choose **Delete**. Any transactions in that category become uncategorized. Categories synced from your bank can't be deleted, since your bank keeps sending them. You can always rename them instead. ## How transactions get a category A transaction's category can come from three places, in order of precedence: 1. **Your bank**, which provides a default category when it's available. 2. **A rule**, which can override the bank's category. See [Rules](/your-data/rules). 3. **You**, by setting it yourself in the app, the API, or the MCP. A category you set by hand always wins, and rules won't change it.
