Privacy

The app keeps everything on your phone. The site keeps almost nothing.

Last updated 14 September 2026.

This page covers NoLie Wi-Fi, the Android app, and nolielabs.tech, the website. It is written to be read, not scrolled past. If anything here turns out to be wrong, email taylorjcwbray565@gmail.com and we'll fix the page or the app, whichever is lying.

The short version

The app has no account and no server. Nothing you measure leaves your phone. The website sets no cookies and runs no advertising. The only personal data we can ever hold is an email address you choose to give us, and you can have it deleted by asking.

The app

NoLie Wi-Fi runs entirely on the device. There are no accounts, so there is nothing to sign in to and nothing that identifies you. The signal readings, the names you give your rooms, the name of your network, the diagnoses and the history are stored in one file on your phone. There is no server to send them to, so they are never sent. We can't see them. Nobody can.

Uninstalling the app deletes everything. There is no copy anywhere else.

Why the app asks for location

This is the part that makes people nervous, so here it is in full. Android will only tell an app about Wi-Fi signal strength and nearby networks if that app holds the location permission. The reasoning is Android's: a list of nearby networks could, in theory, be used to work out where you are. So the permission is required to read Wi-Fi at all.

That is the only reason NoLie Wi-Fi asks for it. The app never reads GPS. It never records where you are. It never transmits anything. It uses the permission to read the strength of your own Wi-Fi where you're standing, and nothing else. The phone's own location switch also has to be on while you check a room, for the same Android rule. On Android 13 or later there is a second prompt, for nearby devices, which does the same job.

If you refuse the permission, the app can't read the signal and says so. It doesn't nag.

The speed test, the one thing that uses the internet

Signal strength alone can't tell distance from interference. So the app can optionally run a short speed test while it listens to a room: it downloads about 5 MB and uploads about 2 MB, over your own Wi-Fi, to Cloudflare's public speed-test service. That is an internet request, so it is the one place where anything leaves the phone.

What is sent: a bag of zeros, to measure the upload. Nothing about you, your rooms, your network or your phone is included. Like any internet request it carries your IP address, which Cloudflare handles under its own privacy policy. We don't run that server and we don't receive anything from it.

The app asks before the first speed test. You can say no and everything else works. You can switch it off or on later in Settings.

Paying for the unlock

The one-off £4.99 unlock is sold through Google Play. Google takes the payment, so we never see your card. We receive confirmation that the purchase happened, not your name or email. Google's own privacy policy covers the payment.

The website

nolielabs.tech sets no cookies. There is no advertising, no advertising network, no social-media button, no embedded video and no third-party font service. The typeface is served from our own server.

We count visits with cookieless analytics that we host ourselves. It records that a page was viewed, which page, roughly when, the referring site if there was one, and the country, worked out from your IP address and then discarded. It doesn't store your IP address, doesn't set a cookie, doesn't fingerprint your browser and can't follow you between sites. It exists so we know whether anyone reads this site. That is the whole of it.

Our web server keeps standard access logs, which include IP addresses, for a short time for security and to fix faults. They are deleted within thirty days and are not used for anything else.

The early-access list

If you leave an email address to be told when an app ships, we store the address, which list you joined and the date, in a file on our own server. Nothing else: not your IP address, not your browser. No third-party list service holds it. We use it to send one email when that app is out. There is no newsletter and no follow-up.

When someone signs up, the server sends us a short notice saying that a sign-up happened and how many there are now. The notice doesn't contain the address. To be removed, reply to the one email you get or write to taylorjcwbray565@gmail.com, and the address is deleted.

Your rights

Under UK data protection law you can ask what we hold about you, ask for it to be corrected or deleted, and complain to the Information Commissioner's Office. For the app, the honest answer is that we hold nothing. For the website and the list, email us and we'll deal with it within a few days. You don't need to prove anything or fill in a form.

Children

The app and the site aren't aimed at children and collect nothing that would make the question matter. If a child has left an email address, tell us and we'll delete it.

Changes

If we ever change what the app or the site does with data, this page changes first and the date below moves. We won't quietly widen it.
