What Hallie remembers

What she keeps track of

Hallie keeps track of three kinds of things you mention:

• People. Who they are to you and what’s going on between you: your sister, your manager, the roommate you argued with.
• Plans. Things you’ve said you’re going to do, such as an interview on Thursday or a trip next month.
• Events. Things that happened or are about to: a promotion you’re nervous about, a date, an exam.

She builds this from what you send in her thread, and it adds up over time. If you call her, what you say on the call carries over too.

She sees only her own thread. She can’t read your other chats, your calendar or your email, so she knows what you’ve told her and nothing else.

How it shows up in conversation

There are two places you’ll see it.

• In her replies. When you bring up your sister again, she already knows who your sister is and what you said last time. You don’t start from the beginning.
• In the texts she starts. After you’ve texted her, she starts conversations too, usually about something you told her. If you mentioned an interview, she may ask how it went.

If you go quiet she checks in once or twice, then waits for you. Ask her to stop starting conversations and she stops.

Where it goes wrong, and how to correct her

She can miss a detail or get one wrong. She might get a name or a date wrong, or not bring up something you expected her to. She isn’t an archive of everything you’ve said, and you may need to remind her.

To correct her, say so in the thread, in plain words:

it’s my cousin who’s moving, not my sister

The same goes when something changes. Tell her you and your partner broke up, or that you have a new manager, and she works from that.

What she doesn’t offer

• No memory screen. You can’t open a list of what she remembers, and you can’t edit or remove single entries. You see what she has kept by what she brings up, and you correct her in the thread.
• No reset switch. You can’t wipe what she remembers yourself. That goes through a deletion request.

How deletion works

Email hello@hallie.io and ask for your data to be deleted. The request covers your conversations, what she remembers, and any call recordings, transcripts and memories that came from calls.

The privacy policy notes that a limited amount may be kept where needed for legal, security, fraud-prevention, dispute or backup reasons.

Until you ask, we keep conversation history and memory while they’re needed to provide the service. Deleting the thread on your own phone removes your copy of the messages. It doesn’t send us a deletion request.

Depending on where you live, you may also have the right to access the personal data we hold. Email the same address to ask.

On who processes your messages: they are processed by outside AI providers to write her replies. We don’t sell personal data, use conversations for advertising, or show them to other users.

If you want a memory screen you can edit

If you want to read what your companion has stored and edit it yourself, two products document that on their own pages. Replika has a Memory screen where you can scroll through saved memories and read or remove one. Pi has a Manage Memories setting where you can add, delete and update what it remembers. If reading and editing that list matters most to you, one of those is the better fit; if you’d rather not manage a list and want to be asked about the interview or the trip you mentioned, Hallie is.

Questions

Does Hallie remember everything I tell her?

No. She keeps track of the people, plans and events you mention, and she can miss a detail or get one wrong. Remind her or correct her in the thread.

Can I see what Hallie remembers about me?

Not as a list. There is no memory screen. You see what she has kept by what she brings up, and you correct her in the thread.

How do I fix something Hallie has wrong?

Tell her in the thread in plain words, for example that it was your cousin and not your sister. She works from the correction.

Does Hallie remember what I say on calls?

Yes. Calls are transcribed, and what you say carries over so she can pick it up later in the thread.

How do I delete what Hallie remembers?

Email hello@hallie.io and ask for your data to be deleted. The request covers conversations, memories, and call recordings and transcripts.
