What Sureno knows about you
Short version: your browsing stays on your Mac, there is no Sureno account, and Google user data is only requested when you choose to connect Google Workspace features.
Effective date: October 2, 2026. This Privacy Policy applies to Sureno Browser (the macOS desktop app) and the website at sureno.ai. Operator contact: support@sureno.ai.
Google user data
If you sign in to Google from Sureno and grant access, Sureno may request the following Google API scopes so New Tab and related features can show your own information on your Mac:
- Gmail (
gmail.readonly) — unread inbox previews, message metadata (from, subject, date, snippet), and optional package-tracking import from mail you already have. - Google Calendar (
calendar.events.readonly) — upcoming events on your primary calendar for an on-device agenda view. - Google Drive (
drive.metadata.readonly,drive.file) — recent file names and links you already own, and files Sureno creates or uploads at your request. - Google Tasks (
tasks) — task lists and items you choose to view or update in Sureno. - Basic profile (OpenID / userinfo) — your name, email address, and profile picture so the app can show which Google account is connected.
How Sureno uses Google user data
Google user data is used only to provide and improve user-facing features you explicitly use in Sureno Browser (inbox previews, calendar agenda, Drive shortcuts, Tasks, and related New Tab panels). Sureno does not use Google user data for advertising, credit scoring, or surveillance.
How Sureno stores Google user data
OAuth access and refresh tokens are stored on your Mac, encrypted with the operating system credential store (Electron safeStorage). Cached previews (for example unread mail rows or calendar items) stay in local app storage on that same Mac. Sureno does not operate a cloud account that receives or syncs your Google mailbox, calendar, Drive, or Tasks content.
How Sureno shares Google user data
Sureno does not sell Google user data. Sureno does not share Google user data with third parties for advertising, data brokers, or unrelated products. Requests go to Google's APIs to fetch the data you authorized; Sureno does not upload that data to sureno.ai servers for storage or analysis. If you later ask an optional AI assistant to help with content you paste or select, that is a separate action under your AI provider settings and is not an automatic transfer of your Google Workspace data.
Google API Services User Data Policy — Limited Use
Sureno's use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements. In particular:
- Google user data is not transferred to others unless necessary to provide or improve user-facing features, to comply with applicable law, or as part of a merger/acquisition with notice to users — and even then only consistent with Limited Use.
- Google user data is not used for serving advertisements.
- Google user data is not read by humans except with your affirmative consent for specific messages, for security/compliance investigations, or where required by law — and Sureno's default architecture keeps that data on-device so human review is not part of normal operation.
Revoking access and deleting Google data
- Disconnect Google inside Sureno (sign out / disconnect) to delete stored tokens and local Google Workspace caches from the app.
- You can also revoke Sureno at Google Account → Third-party access.
- Uninstalling Sureno (Applications → Trash) removes the app's local storage, including any remaining Google tokens and caches on that Mac.
What stays on your machine (non-Google browsing data)
- Your history, bookmarks, open tabs, projects and notes.
- Your settings, including anything you type into Settings → AI.
- Anything the news feed remembers about what you have read.
None of it is uploaded to a Sureno account: Sureno has no account system and no server-side profile for browsing data. Until sync ships, this data lives on one Mac, and if that Mac goes, it goes.
What leaves your machine, and when
1. The pages you visit
Sureno requests them, like any browser. It does not report them to Sureno.
2. Searches
Typing in the omnibox sends your query to the search engine you have chosen, which is Google by default and changeable in Settings.
3. Assistant questions
Only when you send one. What goes with it is exactly what the context chips above the input show — typically your question plus the selected text or the readable body of the current page. Turn a chip off and that content is not included. Choose a local provider such as Ollama and nothing leaves your Mac at all. Health context is off until you switch it on deliberately.
4. Update checks
The app asks an update URL whether a newer build exists. That request necessarily reveals your IP address and current version to that server, and nothing else. It can be turned off.
5. Favicons and news images
The start page loads site icons and article thumbnails from the publishers and from Google's favicon service, which means those hosts see a request for the icon of a site you are looking at. Turning the news feed off stops it.
What we do not do
- No selling or sharing of personal data or Google user data for advertising or data brokerage.
- No advertising profile, no cross-site identifier, no fingerprinting of our own.
- No background reading of pages by the assistant.
- No silent rewriting of the links you click into affiliate links.
This website
sureno.ai serves product pages, explainers, free tools, live data pages, news and recipe pages. It sets no cookies and uses no third-party analytics or advertising trackers.
How we count visits
To learn which pages are useful, the site counts visits itself, without cookies and without a third-party analytics company. When a page loads, your browser sends us the page address, the site that linked to it (if any), your screen size, language and time zone, and later how long the page was visible and how far it was scrolled. We also store the IP address of the visit and an approximate location (city, region and country) looked up from that address, plus the browser and device type. This is used only to see who reached sureno.ai, which pages they opened and how long they stayed. Visit rows, including the IP address, are deleted after 90 days. Daily totals (page, number of views and time spent) are kept without IP addresses. If your browser sends Do Not Track or Global Privacy Control, nothing is counted at all.
Email lists
If you join the Windows waitlist, the morning briefing list or the updates list, we store your email address, which list, the page you joined from and when. The morning briefing asks you to confirm that address before anything else is sent, then sends one email each morning. Delivery goes through Resend, which sees the address only to carry the message. The list is used only for what you joined, never sold or shared, and deleted on request (email support@sureno.ai, or the unsubscribe link in the briefing).
Free tools
The PDF, image, text and calculator tools run entirely in your browser. Files and text you use with them are never uploaded to us or anyone else.
Explainers written with AI
Sureno Explained articles are drafted with an AI service (currently Meta's Model API). Only public material is sent to it: topics, public sources and drafts. Nothing about visitors is ever sent. See our editorial standards.
Customer chat
The chat button on sureno.ai saves the conversation, the page you opened it from, and the time, so we can reply in the same chat. What you write is also sent to the AI provider set in our admin (Meta's Model API, unless we change it) so it can draft an answer. That is a different model from the one that drafts public articles: article drafts use a discounted model that may be used for training, and customer messages are not sent to that model. The token that reconnects you to your own chat is stored in your browser, not in a cookie. Chats are deleted after 180 days. Email support@sureno.ai if you want one deleted sooner. An email address is saved only if you type one into the chat.
Things stored in your own browser
Your choice of day or evening colours, ingredients you tick off on a recipe, and the token for a support chat you started, are remembered in your browser's local storage. The colours and the recipe ticks never leave your device. The chat token is sent back only so we can show you that same conversation.
Other services pages load
Pages load fonts from Google Fonts. News pages load headline images from the publishers, and the sky page may show NASA's picture of the day from nasa.gov; those services see a request from your browser. Standard server access logs exist, as on every web server. If sponsored recommendations are ever switched on in the news section they will be labelled “Sponsored” and loaded in an isolated frame.
Emails, reminders and counts
Every email list (the morning email, the Windows waitlist, Sureno news) asks you to confirm by email before anything is sent, and every email has a one-click unsubscribe. Browser reminders are off until you press “Remind me”; we keep only the reminder address your browser gives us, the topics you picked and your time zone, never your IP address, and you can turn them off at any time. Games keep your streaks on your device; the site only counts how many games were finished each day. Health logs, flash cards and bookmarks stay in your browser. Text pasted into Scam check is not stored; when the AI explanation is on, the text is sent to our AI provider with long numbers, phone numbers and email names hidden first. A future version of the browser may send one anonymous “installed” count (version and platform only, no identifier).
Children
Sureno Browser is not directed at children under 13, and we do not knowingly collect personal information from children under 13. If you believe a child has provided personal information, contact support@sureno.ai and we will delete it from systems we control.
Things that are demonstrations, not protection
Parts of the app are interface demonstrations and say so where they appear: the tracker-shield counters and the VPN screen. They do not filter or tunnel your traffic. We would rather tell you here than let a satisfying number imply a protection you do not have.
Deleting everything
Drag Sureno from Applications to the Trash. That removes the app and its storage, including any local Google tokens and caches. Your other browsers are untouched, because the import copied rather than moved.
Changes to this policy
If this policy changes materially, we will update the effective date on this page. Continued use of Sureno after a material change means you accept the updated policy for new activity.
Questions about privacy or Google user data: support@sureno.ai. Related: Terms of Service. If this page and the app ever disagree, the app is the bug — tell us and we will fix it.
Try a calmer browser for a week
Sureno copies your bookmarks and passwords rather than moving them, so your old browser stays exactly as you left it. If Sureno is not for you, uninstalling takes under a minute.
