Privacy Policy
Last updated: 6 November 2026
Sweep is published by Hugo Software. This policy explains, in plain language, what the app does with data. The short version: nothing you scan leaves your phone.
What Sweep does
Sweep is a scanning aid. During a sweep it listens to Bluetooth Low Energy advertisements around you and scans your local Wi-Fi network for devices, then shows you a report of what it observed.
What the app reads
While a sweep is running, Sweep reads:
- Bluetooth advertisements: the broadcast address, any broadcast name, signal strength, and the time each broadcast was heard. These are public signals that nearby devices transmit continuously.
- Local network information: IP addresses on your own network, names and services that devices announce over SSDP/UPnP and mDNS, which common TCP ports answer, and hardware addresses in the rare cases the operating system still exposes them.
What happens to it
This information is held in your phone's memory for the length of the sweep and used only to build the report you see on screen. It is not uploaded, not stored on any server, and not shared with anyone. If you leave the report without saving it, it is gone.
Sweep contains no analytics SDK, no advertising SDK, and no crash-reporting SDK. There is no account system: no sign-up, no login, no profile.
What is saved on your phone
- Saved reports and "Mine" labels (version 1.1.0 and newer, Sweep PRO): stored only if you choose to save a report or label a device. They stay on this phone and are left out of Android backup and device transfer. You can delete them in the app at any time.
- PDF reports: a PDF is written to the app's temporary storage only when you ask for one, so that you can share it. It stays about a day so the app you shared it with can still read it, and is removed the first time you open Sweep after that. A copy you send or save somewhere else stays there, and it is yours to delete. A report can contain addresses and device names; you can choose a PDF with these hidden before sending it to someone.
- Purchase state: a small local record of whether you have Sweep PRO or the older one-time unlock.
Location
Sweep does not collect your location. The Bluetooth scanning permission is declared with Android's neverForLocation flag, which tells the system that this app must not use Bluetooth signals to derive location, and we do not.
On Android 12 and newer, Sweep has no location permission. On Android 11 and older, the operating system refuses to return Bluetooth scan results unless a location permission is present, so on those versions only the system may ask for it. Even there, Sweep does not read, store or transmit your location.
Internet access
Sweep requests internet access because scanning your local network means opening connections to addresses on your own network and sending discovery messages on it. Links you open from the app, such as this page, open in your browser. The app itself sends no scan data to any remote server.
Purchases
Subscriptions and purchases are processed by Google Play. Google handles the payment; we never see your name, card details or address. We receive only the aggregate purchase records Google provides to developers. Google's handling of that transaction is covered by Google's own privacy policy.
Children
Sweep is not directed at children.
Your rights
Because Sweep stores no personal data on any server, there is nothing for us to export or delete on your behalf. Everything is on your phone and under your control. See our data removal page for details.
Changes
If this policy changes, the updated version will be posted on this page with a new date.
