# Erase a person's data from every AI store

By [Agent Wranglers](https://agentwranglers.se/authors/agent-wranglers). Updated 2026-10-21.

For AI agents: [llms.txt](https://agentwranglers.se/llms.txt) is a short guide that sends you to the rules your problem needs, and [rules.json](https://agentwranglers.se/playbook/ai-features/rules.json) holds every rule of this playbook as JSON.

- Level: Required
- Chapter: [Logs, privacy and feedback](https://agentwranglers.se/playbook/ai-features/logs-privacy-and-feedback)
- Rule: When a person's data is deleted, delete it from every store an AI feature fills. That includes vectors, prompt text, answer caches, agent memory, run traces and files kept by the model provider.
- Risk: A law broken
- Applies when: The project it uses AI models.
- How: Add each AI store to the map from [Map every store that holds personal data](https://agentwranglers.se/playbook/compliance/records-and-data-map/data-map). Store the owner's account ID on every chunk, cached answer, memory item and trace row, so one query finds them. Providers keep data too. The OpenAI Responses API stores each response for at least 30 days unless the request sets `store` to false. Uploaded files, vector stores and conversations stay with a provider until you delete them through its API. Turn off provider storage a feature does not need, and record the provider's IDs for what it keeps. Call these deletes from the one delete function in [let people see and delete their data](https://agentwranglers.se/playbook/website/privacy/data-requests).
- Check: Create a test person, use every AI feature as them, then delete them. A search of each AI store and a list call to each provider store find no row or file with their ID. A search of the code finds no Responses API call without an explicit `store` value.

## Examples

**Using these examples:** they show one way to follow this rule. Keep the behaviour and the check, not the syntax. Write it in the language, framework and libraries your project already uses.

### TypeScript example

```ts
export async function eraseFromAiStores(accountId: string) {
  await db.query('DELETE FROM chunks WHERE owner_id = $1', [accountId]);
  await db.query('DELETE FROM ai_call_text WHERE account_id = $1', [accountId]);
  await db.query('DELETE FROM agent_memory WHERE account_id = $1', [accountId]);
  await answerCache.deleteByTag(`account:${accountId}`);
  const { rows } = await db.query('SELECT provider_file_id FROM provider_files WHERE account_id = $1', [accountId]);
  for (const { provider_file_id } of rows) await openai.files.delete(provider_file_id);
  await db.query('DELETE FROM provider_files WHERE account_id = $1', [accountId]);
}
```

### Python example

```python
def erase_from_ai_stores(account_id: str) -> None:
    for table, column in [("chunks", "owner_id"), ("ai_call_text", "account_id"), ("agent_memory", "account_id")]:
        db.execute(f"DELETE FROM {table} WHERE {column} = %s", (account_id,))
    answer_cache.delete_by_tag(f"account:{account_id}")
    for (file_id,) in db.execute("SELECT provider_file_id FROM provider_files WHERE account_id = %s", (account_id,)):
        openai_client.files.delete(file_id)
    db.execute("DELETE FROM provider_files WHERE account_id = %s", (account_id,))
```
