Locked down. Architecturally private.
Qbit is useful because of what Qbit knows about you, and that only works if it stays yours. Privacy isn’t a setting we added later. It’s the shape of the system: your memory and conversations live encrypted in Qbit’s own architecture, the AI models underneath are tools Qbit uses rather than places your life is kept, and every control is in your hands.
What we commit to.
- Never sold. Never used for advertising.
- Not training material for the big LLMs.
- Encrypted, in Qbit’s own architecture.
- Delete means delete.
Inside Qbit. Never inside a model.
Here’s the structure, because the structure is the promise. Your memory, your folders, your documents and your conversations live in Qbit’s own systems, under your account’s own partition, encrypted. The AI models underneath never hold the picture of you.
When you ask something, the Qbit Cobalt Brainstem assembles only the context that one answer needs: the facts you asked Qbit to keep, the relevant parts of the documents in scope, and the thread you’re in. The strongest specialist model for that job gets that much and nothing more, does the thinking, and the answer comes back up as Qbit. That is the Brainstem’s job in privacy: no model ever gets more than the answer in front of it needs.
- YouOne question, on any device, in any of 97 languages.
- QbitYour memory, folders, documents and conversations, encrypted under your own account, plus Qbit’s personality and privacy rules.
- The Cobalt BrainstemAssembles only what this one answer needs, picks the specialist, and returns the answer as Qbit.
- Specialist modelsSeveral, from more than one provider. Each sees one answer’s context, and every one is contractually barred from training on it.
The architecture does the heavy lifting.
Your data is kept in your account’s own partition, encrypted, reachable only through Qbit, and seen by nobody else on Qbit unless you invite them into a folder on purpose.
- Your own partition.Every conversation, memory and file is stored under your account and nobody else’s. Another person’s request simply can’t reach your rows.
- Encrypted, with short-lived links.Documents and photos are stored encrypted. When you open one, Qbit signs a link just for you that expires within minutes.
- Kept in Qbit, not in a model.The complete picture of you lives only in Qbit. The AI models underneath receive the context a single answer needs, and nothing more.
- Need-to-know access.Qbit runs in United States data centers. Staff access is limited to need-to-know, split by role and protected by multi-factor authentication.
The lines we don’t cross.
- Never sold.Your data isn’t sold and isn’t handed to anyone except as needed to run Qbit itself. No data brokers, no lists.
- Never used for advertising.The free plan shows ads to stay free. Your conversations, documents and memories are never handed to advertisers, and no advertising profile is built from them.
- Not training material.Your conversations and documents aren’t used to train AI models unless you turn that switch on yourself. Every provider Qbit works with is contractually barred from training on them.
- No recordings kept.Conversation Mode turns your words into text and discards the audio. Recordings are never stored.
How Qbit is different, and why it matters.
Parents ask us how Qbit compares to the assistants they already know. Here it is, side by side, taken from each company’s own published policies and help pages.
| Qbit | Claude | Gemini | Perplexity | Muse (Meta) | |
|---|---|---|---|---|---|
| Trains its AI on your chats by default? | No. Off until you switch it on in Settings, and anonymized if you do. The models underneath are barred from training on your data. | Yes, unless you opt out in settings. Chats flagged for safety review can be used even after you opt out. | Yes. “If you’re 18 or over, Keep Activity is on by default,” and Google uses chats to improve its services, “including training generative AI models.” | Yes. “AI Data Retention” is on by default, and switching it off stops future use only. | Yes. “This setting is on when you first use Muse.” Switching it off also covers past interactions. |
| Can you see everything it remembers, and delete any line? | Yes. Every fact you gave Qbit, the profile Qbit wrote, your dates and every conversation, each one deletable. | Yes, under Settings and Memory, but deleting a chat does not remove the memories made from it. | Partly. You manage the info you have asked Gemini to save. Google’s privacy hub does not say you can see everything Gemini remembers. | Yes. View, delete or switch off saved memories in settings. | Partly. You can edit a memory file and ask Muse to forget, “to the best of its ability.” After a delete, Muse “may still remember information it learned from what you deleted.” |
| Delete means delete? | Yes. Deleted conversations and memories are gone. A closed account is erased after a 30-day change-of-mind window. | Deleted chats leave Anthropic’s back end within 30 days. Memories made from them stay, and chats flagged for safety review are kept. | Mostly. Activity auto-deletes after 18 months by default, but chats a human reviewer has seen “are retained for up to three years.” | Unclear. Data is kept “as long as necessary,” deletion is granted “if required by law,” and backups are kept “as permitted by law.” No timeframe is stated. | Only with a full reset, which wipes everything and “cannot be undone.” |
| Teens, 13 to 17, with a parent in the loop? | Yes. Their own account on a parent’s plan, safety alerts to the parent, sign-in notices and controls per teen. | No. Adults only. Accounts showing signs of a minor are disabled until age is verified. | A separate teen version on the teen’s own Google Account. Google’s privacy hub says nothing about what a parent can see. | No. “Not meant for children under 13,” and no parental controls on Perplexity’s own site and apps as of October 2026. | No. Adults only under Meta’s Muse terms. |
| Where does your data live? | In Qbit’s own encrypted architecture, under your own account. The models see one answer’s context and nothing more. | Inside Anthropic’s systems, with the company that runs the model. | Inside your Google Account, next to your Search and YouTube history, with Connected Apps able to bring in emails, files and photos. | Inside Perplexity’s systems. Its notice lists advertising partners as recipients of identifiers and activity for targeted advertising. | Inside Meta’s systems, with the company behind Facebook and Instagram. |
| Ads? | The free plan shows ads to stay free. Your conversations never target them and are never sold. Qbit+ has none. | None. “Claude will remain ad-free,” with a note that Anthropic will say so if that ever changes. | None in chats today. “Your Gemini Apps chats are not being used to show you ads,” and Google says it will tell you if that changes. | Dropped its ads in February 2026, while its notice still allows sharing with advertising partners. | None at launch, and Meta says Muse conversations stay out of its ad systems. |
Nothing hidden, nothing you can’t undo.
Most assistants keep a profile you can’t see and a history you can’t really clear. Qbit shows you everything and gives you the button.
- Memory you can read.The facts you gave Qbit and the profile Qbit wrote from your conversations are both listed in the app, for you and you only. Edit a line, delete a line, or clear the lot.
- Conversations, one or all.Delete a single conversation, a whole thread, or everything in Recents. Both kinds of delete are permanent.
- Links you can switch off.Every answer you’ve sent as a link sits in one list with its open count. Revoke one and it stops working for everyone, immediately.
- Take a copy any time.Download everything Qbit holds about you as a PDF, a Word document or raw JSON, in a tap.
- Delete your account, for real.Thirty days to change your mind, then your profile, conversations, documents, photos, folders and invitations are erased. Anything collaborators uploaded is handed back to them.
- Every device, every sign-in.See each device signed in, sign any of them out, sign out everything but the one in your hand, and review every sign-in attempt, failed ones included.
The unglamorous parts, done properly.
- Passwords are hashed.Stored in a form nobody can read back, us included. Sign in with Google or Apple if you’d rather not have one at all.
- Sessions end.A sign-in lasts 30 days at most, and you can end any session from any device, instantly.
- Brute force is rate-limited.Repeated sign-in attempts are slowed and then blocked, per account and per address.
- Tested from the outside.Qbit is examined by an independent security firm, and what they find gets fixed.
Private by default. Open only to the people you invite.
- Only what’s in the folder.People you invite see that folder and what’s inside it. Your other folders, files and conversations stay yours.
- Roles you choose.Manager, Collaborator or Viewer, per person, changeable any time. Remove someone and the folder leaves their account.
- Gone means gone.Delete something from a folder you collaborate in and it’s gone for everyone in the folder, not just for you.
Straight answers about privacy.
Do you train AI models on my conversations?
Not unless you ask us to. Your conversations and documents aren’t training material by default, and every provider Qbit works with is contractually barred from training on them. There’s one switch in Settings, “AI Data Retention”, which is off until you turn it on, and uses anonymized queries if you do.
What do the AI models actually see?
One answer’s worth of context: the facts you asked Qbit to keep, the relevant parts of the documents in scope, and the thread you’re in. Never your whole history, never your account, never the complete picture of you. That stays in Qbit.
Can Qbit staff read my conversations?
Access to personal information is limited to the people who need it to run the service, split by role and protected by multi-factor authentication. Nobody browses conversations for fun, and the systems are built so they can’t.
Where is my data stored?
In United States data centers, encrypted, under your own account’s partition. Documents and photos are opened through signed links that expire within minutes.
What happens when I delete my account?
Your account switches off straight away and you have 30 days to change your mind by signing back in. After that, your profile, conversations, memories, documents, photos, folders and invitations are erased, and anything collaborators uploaded into your folders is handed back to them.
Do you sell my data to advertisers?
No. Your data is never sold and never handed to advertisers. The free plan shows ads to stay free, and nothing about you is traded for them.
