2. What this policy covers
This policy covers this website, the Brello 1.0 app for Android and iPhone (‘Brello 1.0’, version 1.0.0, released on 4 October 2026), and messages you send us. In it, ‘personal data’ means information that identifies you or could be linked to you.
Brello Super Intelligence is in development and isn’t available. We will publish a dedicated privacy notice for it before anyone outside our team uses it. That notice will describe exactly what is processed on your device, what (if anything) is processed in sealed compute, and what is kept, and it will be consistent with the Brello Charter.
3. This website
No cookies, analytics or trackers. This site sets no cookies and runs no analytics, advertising, session-recording or social-media scripts. Every font, image and script is served from this site, so visiting it doesn’t send requests to third parties.
Nothing stored in your browser. The site writes nothing to your browser’s local or session storage.
Server logs. Like any website, the service that hosts this site receives the standard information your browser sends with each request: IP address, browser type, the page requested and the time. Our host uses it to deliver the site and protect it from abuse, and keeps it only for a short period.Log retention to be confirmed We don’t use it to identify or profile visitors. The legal basis is our legitimate interest in delivering and securing the site.
4. When you contact us
When you email us, we receive your email address and whatever you choose to write.
- Why: to reply to you.
- Legal basis: our legitimate interest in answering messages you send.
- How long: correspondence is kept only as long as needed to deal with it.
- Who else: our email provider processes these messages on our behalf, as a processor, meaning it handles them only on our instructions. We don’t share them with anyone else, and we never add you to marketing lists.
5. Brello 1.0 on your phone
Brello 1.0 processes your questions, photos and answers on your phone, and we don’t receive any of them. The two tables below list what stays on the phone and the only requests that leave it.
Processed and stored only on your phone
| Data | Where it lives |
|---|---|
| Your questions | Processed by the language model running on your phone |
| Brello’s answers and reasoning (‘Thought process’) | Generated on your phone and stored with the chat |
| Photos you attach | Copied into Brello’s private app storage. Never uploaded, and a message with a photo never triggers a web search. |
| Chat history | A single file in Brello’s private app storage |
| Settings (theme, web search, Think harder, GPU use, chosen model) | Android’s private app preferences |
Brello’s data is excluded from Android cloud backups and from device-to-device transfer, so your chats aren’t copied to a backup service or to a new phone. Brello contains no analytics, crash-reporting or advertising software, and it has no account system. We don’t receive any of the data above.
What leaves your phone, and when
| When | What is sent | To whom | Started by |
|---|---|---|---|
| You download a model (once per model) | A standard file download request | Hugging Face, which hosts the open model files | You, when you start the download |
| You use web search (off by default) | The search text: a cleaned-up version of your question, sometimes with up to ten words of your previous question for context | A search engine: DuckDuckGo, Bing, Brave Search, Google News or Wikipedia | The ‘Search the web’ setting, or your choice on the ‘Search the web for this?’ card |
| The same search | Ordinary requests for up to four result pages | The websites in the results | As above |
| You tap a source | The page opens in your browser | That website | You |
These requests go directly from your phone. There’s no Brello server, proxy or relay in between, so we hold no logs of them. Search and page requests send the ‘Do Not Track’ and ‘Global Privacy Control’ signals. The search engines and websites you reach receive the request, including your device’s IP address, as they would for any web request, and they handle it under their own privacy policies. The invisible browser Brello uses for search is wiped (cookies, cache and storage) after three idle minutes, and search results are kept in memory only, for fifteen minutes, and are gone when the app closes. Source cards show letter marks drawn on your phone, so no site icons are requested. The Brello 1.0 system card describes the same requests in technical detail.
Permissions
Brello asks for internet and network-state access, for model downloads and optional web search, and for foreground-service, notification and wake-lock permissions, so that a large download can continue in the background with a notification. Camera and photo access are requested through Android’s system picker only when you choose Camera or Photos. Brello doesn’t request contacts, location, microphone, SMS, calendar or storage-wide access.
Deleting your data
Swipe left on a chat to delete it, or use ‘Delete all chats’ in Settings, which asks you to confirm. Uninstalling Brello removes all of its data from your phone. Because none of it reaches us, there’s nothing for us to delete on our side.
6. What we don’t do
- We don’t sell, rent or trade personal data.
- We don’t buy data about you from third parties.
- We don’t run advertising or build advertising profiles (Brello Charter, commitment 02).
- We don’t train models on your conversations (Brello Charter, commitment 01).
7. Your rights
Depending on where you live, data-protection law (including the UK and EU GDPR and the California Consumer Privacy Act) gives you rights over personal data we hold about you:
- to access it and receive a copy;
- to have it corrected or deleted;
- to restrict or object to how we use it;
- to withdraw consent at any time;
- to complain to your local data-protection authority.
For Brello 1.0, everything lives on your device and is already under your control. For anything you’ve sent us by email, write to [email protected] with ‘Privacy request’ in the subject line, and we’ll respond within the time the law requires. We won’t treat you differently for exercising these rights.
8. Where data is processed
Brello 1.0 processes your questions, photos and answers on your phone, wherever you are. The only personal data we receive is what you send us by email. Our email and hosting providers may process it in countries other than yours. Where they do, we rely on the safeguards the law requires for such transfers.
9. Children
This website and Brello 1.0 aren’t directed at children under 13, and we don’t knowingly receive personal data from them. If you believe a child has sent us personal data, contact us and we’ll delete it.
10. Security
The most effective protection is not holding data in the first place, and that’s how Brello is designed. Where we do hold data, such as emails, we limit who can access it. If you find a security issue, please tell us through our responsible disclosure policy.
11. Changes to this policy
If we change this policy, we’ll update the date at the top. If a change is material, we’ll explain it in plain language before it takes effect. A change will never apply weaker terms to data you’ve already shared with us. Each change is recorded below, and earlier versions will be listed here with their dates and kept available.
- This version. Covers this website, Brello 1.0 (version 1.0.0) and messages you send us.
