Privacy policy

Last updated: October 1, 2026

BrushLock has no accounts, no servers of its own and no analytics. What you set up and what you do stays on your iPhone. The only thing that talks to a third party is the Google AdMob ad on the emergency exit, and this page explains how.

Who is responsible

BrushLock is published by Jose Sanchez Gonzalez (Spain). For any privacy question, write to brushlock@raidrdev.com.

What the app stores, and where

Apps to lock

You pick them with the iOS picker (Screen Time). iOS hands back an opaque reference, not names: BrushLock doesn't know which apps they are and can't read or send them.

Windows, settings and history

Your schedule, streak and brushing history are stored only on your iPhone, and sync to your Apple Watch if you use one, directly between your devices. We don't receive them.

Bluetooth

If you use an Oral-B toothbrush, the app reads what the brush broadcasts to confirm it's being used. The paired brush's identifier is stored on your iPhone.

Microphone

Only to recognize your toothbrush's motor by sound. The audio becomes a few numbers on the spot and is discarded: it isn't recorded, saved or sent off the iPhone. The only thing kept is a numeric signature of your brush's sound, on your iPhone.

Apple Health

Only if you turn on “Save to Health” in settings: the app saves your brushing sessions (date, time and duration) to the Health app on your iPhone. BrushLock only writes to Health and never reads anything from it. That data doesn't leave your device, isn't sent to servers of ours, and is never used for advertising or shared with third parties, including Google AdMob.

Diagnostic report

If your toothbrush doesn't work well, the app can prepare an email with technical details. You see it and decide whether to send it; if you don't, it reaches no one.

Advertising

On the emergency-exit screen you can watch a rewarded ad, always optional. It's served by Google AdMob. To serve and measure it, Google may collect data such as your IP address, device identifiers and how you interact with the ad.

BrushLock requests non-personalized ads and doesn't ask for permission to track you across apps (ATT). Google's SDK starts when the app opens and may load an ad ahead of time even if you never watch it. In the European Economic Area and the United Kingdom, Google's consent form appears when you tap “watch an ad”, before any ad is shown.

How Google handles that data: Google's privacy policy and how Google uses data from apps that use its services.

Permissions the app asks for

• Screen Time, to lock the apps you pick.
• Bluetooth, to detect your Oral-B toothbrush.
• Microphone, to recognize your toothbrush by sound.
• Health, only to write your brushing sessions if you turn on “Save to Health”.

You can withdraw them any time in iOS Settings. Without the microphone, Bluetooth or Health, BrushLock still works (with the timer, in the first two cases).

Children

BrushLock isn't directed at children under 13 and doesn't knowingly collect data from anyone.

How long data is kept

On your iPhone, until you delete the app: uninstalling removes everything BrushLock stores. What you saved to Health is yours and stays there: delete it from the Health app if you want. There's no copy on any server of ours.

Your rights

Since we don't hold your data, there's nothing to ask us to show, correct or delete: you have it and you control it from your iPhone. For the data Google handles through ads, you can exercise your rights with Google. And if you have any question, write to brushlock@raidrdev.com.

Changes

If any of this changes, we'll update this page and the date above.
