SieluPrivacy Policy
What we collect
Your sign-in identifier, the name and email your sign-in provider shares with us (an Apple private relay address is fine), your birth date, optional birth time and birth place, your assessment answers, and the notes Sielu keeps from your conversations.
Why
To build your chart, generate your persona card, and let Sielu remember context across sessions.
What we don't do
We don't sell your data, we don't use your private notes to train models, and we don't reuse details you record about other people for anything beyond showing them back to you. Deleting a person deletes everything Sielu knew about them.
How Sielu's replies are generated
Sielu's replies are not written on your phone. When you send a message on the Ask page, or open a monthly or yearly reading, text is sent over an encrypted connection to a relay we operate, which forwards it to DeepSeek — the third-party language-model provider that generates the reply. Our relay runs on Cloudflare's edge network in the United States. It holds the model credentials and passes text through; it does not generate the reply itself.
Who the provider is
Hangzhou DeepSeek Artificial Intelligence Co., Ltd. DeepSeek's own privacy policy states that it collects, processes and stores data in the People's Republic of China. What DeepSeek may do with text sent to its API is governed by DeepSeek's privacy policy, not by this one: its published terms currently permit it to use API content to develop and improve its own models, and offer a setting to opt out of that. We do not train models on anything you write, and we do not sell your data.
What is sent
- The message you just wrote — only that message. Earlier turns in the thread are not sent.
- Up to six short notes Sielu keeps, selected as relevant to that message. Each is a summary of at most 600 characters. Sielu stores summaries, never transcripts.
- Which subject the conversation is pointed at and, if it is about a person you have added, that person's name as you typed it.
- The title of your persona card.
- For a monthly or yearly reading: your sun sign, your four-letter type, your archetype title, up to four of your own notes, and that reading's scores.
- Before a reply is generated, your message is sent once more on its own so it can be checked for signs of crisis. That check is what puts a support card on screen.
What is not sent
- Your birth date, birth time, or birth place.
- Your sign-in identifier, your name, or your email address.
- Notes attached to any other person. Retrieval is filtered to one subject before the request is built — it is a filter in our code, not an instruction to the model.
- Anything at all, if you never open a conversation or a monthly or yearly reading.
Crisis-related content
Anything you say in a moment of crisis is never written to memory. A turn flagged by the crisis check cannot be stored as a note, so it can never be retrieved into a later request. The support card you see is built from our own list of services for your region — it is never generated by the model.
Your rights
Export everything, delete a single note, or delete your account outright. Deleting your account starts a 7-day window, after which your data is permanently removed. All three are in Settings inside the app.
Where we operate
Sielu is offered in the United States only at this time.
