Privacy Policy
Locker Mate for iPhone
The short version
Your locker numbers and session history never leave your iPhone. There are no accounts, no servers of ours, and no analytics. Locker Mate does not upload anything you record in it.
The app does show ads, served by Google AdMob. Google — not the developer — collects device and usage information in order to do that, and may use your device's advertising identifier to personalise what you see. You are asked for permission first, you can say no, and you can remove ads altogether with a one-time purchase.
What Locker Mate stores on your device
The app saves what it needs to do its job, and nothing else:
- the locker number of the session currently running, and when it started
- your session history — locker number, start time and end time for each
- your settings: session goal, auto-end time, theme, and whether the countdown and Live Activity are switched on
- a count of completed sessions, used only to decide when to offer the Remove Ads purchase
- whether you have bought Remove Ads
All of it is written to a private container on your iPhone, shared between the app and its widgets so the Lock Screen and Home Screen can show your timer. It is not synced to iCloud, not backed up to any server of ours, and never transmitted. Nobody — including the developer — can see it.
You can delete any individual session from the Activity tab. Deleting the app removes everything at once. There is no copy anywhere else to request the deletion of.
Advertising
Locker Mate is free and is paid for by a small banner advertisement. That banner is served by Google AdMob, which is a third party operating under its own privacy policy.
To serve ads, Google may collect and process information such as your device's advertising identifier (IDFA), IP address, device type and operating system version, and general information about how ads performed. The developer of Locker Mate does not receive any of this, and receives no information that identifies you — only anonymous, aggregated earnings figures.
Two separate permissions govern this, and you control both:
App Tracking Transparency
On first launch iOS asks whether Locker Mate may track you across apps and websites. That question is Apple's, and your answer is binding on the app.
If you decline, the advertising identifier is not available, and the ads you see are non-personalised — chosen from general context rather than from your interests. The app works exactly the same either way.
You can change your mind at any time in Settings → Privacy & Security → Tracking.
Consent, for the UK and Europe
If you are in the UK or the European Economic Area, you are also shown Google's consent form before any ad loads, as required by UK and EU data protection law. Your choice there determines whether Google may use your data for personalised advertising.
To revisit it later, open the Info tab and choose Ad privacy options. That entry appears whenever the consent form applies to you.
Google's own documentation explains what it collects and why:
Removing ads
Remove Ads is a one-time in-app purchase. Once bought, the banner is gone and no further ad requests are made from the app.
The purchase itself is handled entirely by Apple through the App Store. Locker Mate never sees your name, payment details or billing address — only whether the purchase exists, so it knows to hide the banner. Restoring it on another device asks Apple, not us.
Permissions the app never asks for
Locker Mate does not request and cannot access your location, contacts, photos, microphone, camera, calendar, or any health or fitness data. It is a timer with a number pad; none of that is needed.
Analytics
The app contains no analytics or crash-reporting library of its own, and the developer runs no server that it talks to.
Apple separately provides the developer with anonymous, aggregated App Store statistics — download counts, and crash reports if you have opted into sharing them in Settings → Privacy & Security → Analytics & Improvements. That is a feature of the App Store rather than of this app, it is controlled by your own iOS settings, and it identifies nobody.
Children
Locker Mate is a general-audience app and is not directed at children under 13. Because it displays advertising, it is not suitable for a child-directed audience and it is not part of any children's programme or category.
Your rights
Under UK and EU data protection law you have rights of access, correction, erasure and objection over personal data held about you.
For data held by Locker Mate, those rights are satisfied directly on your device: everything the app stores is visible in the app, can be edited or deleted there, and is destroyed when you delete the app. The developer holds no copy and so has nothing to disclose or erase.
For data held by Google as a result of advertising, those rights are exercised with Google, using the links above and the consent controls described in this policy.
Changes to this policy
If this policy changes it will be updated on this page and the date below will change with it. If a change ever materially affects how your information is handled, it will be described here rather than quietly amended.
