Start with a data map
Before adding personal details to a fictional chat, identify what the service says it stores and which controls it provides. A friendly reply or a lock icon does not answer this. Use an invented character and setting while checking the policy and account interface.
| Data area | Question to resolve | Evidence to look for |
|---|---|---|
| Conversation history | What does deleting a chat remove? | A documented deletion control and its stated scope. |
| Saved memories | Are learned facts separate from the transcript? | A memory screen or policy explaining editing and deletion. |
| Account records | What remains after closing the account? | Retention periods, exceptions, and the account-deletion process. |
| Billing | Does account deletion also stop renewal? | Subscription cancellation instructions from the billing provider. |
Ask a question that can receive a specific answer
If I delete a conversation, are associated saved memories also removed? How long may copies remain in backups? Is conversation content used for model training, and what control applies? Do I need to cancel a subscription separately before closing my account?
These are questions for the provider’s current documentation or support. Sending them to the fictional character is not a reliable way to establish the service’s policy. Keep the relevant policy link and date with your notes.
Use less identifying context
For a café scene, an invented city and a fictional schedule work just as well as your address and actual routine. Avoid copying someone else’s private messages into a character brief. Review any image you plan to upload for visible names, addresses, or other identifying details before deciding to share it.
Interpret an unknown honestly
If you cannot find a retention period or training control, mark it “not established.” That does not prove a particular practice, and it is not permission to assume the most favorable answer. Decide whether you are comfortable using the product with that uncertainty, and limit what you share accordingly.
This guide and the destination are different sites
First Hello’s demo does not submit a conversation. Its outgoing WantYou.ai links do not include your selected scene or calculator values. The site serves its portraits locally, but its font stylesheet still contacts Google Fonts. See how this static guide handles data for the distinction between local interactions and network requests.
