Brick Calculator

Privacy Policy

Play Store Compliance Document • Last updated 23 October 2026

1. Introduction

At ItsMeMomo Developer Portfolio (itsmemomo.com), trust is the foundation of our software. This Privacy Policy explains how Brick Calculator handles your information. It covers Brick Calculator alone — every app we publish has a policy of its own, listed at itsmemomo.com/privacy.

Section 2 covers the anonymous usage statistics and crash reports that Brick Calculator collects, and says exactly what those are. Section 3 covers advertising, which applies to Brick Calculator 1.1+. In every case, the things you actually create stay on your device and are never sent to us.

2. Brick Calculator — Anonymous Usage Statistics

Brick Calculator includes Google Firebase Analytics, so we can see which features people actually use and where they get stuck. It also includes Firebase Crashlytics, so that when the app crashes we find out and can fix it. We have tried to keep this as narrow as it can reasonably be, and we would rather tell you exactly what it is than describe it vaguely.

What the app does send:

  • A random app-instance ID. Generated on your device, not linked to your name, email or Google account, and reset if you reinstall the app.

  • Which screens and features are used, and how long a session lasts. In Brick Calculator it is which tool you used (bricks, plaster or concrete) and the options it was set to — for example a one-brick wall of modular bricks, plaster on both sides, or a round column of M20 concrete — whether the wall had doors or windows taken off, whether you entered prices, feet or metres, and whether you shared an estimate. Never a size, a count, a price or an estimate, and not the region you picked.

  • Your device model, Android version and approximate country, worked out from your IP address. Not a precise location — we cannot see your street, your city or your GPS position.

  • Crash reports. If the app crashes, Crashlytics sends the technical details of the failure: where in the code it happened, your device model and Android version, how long the app had been open, and which screen. It is what lets us fix the crash rather than wait for someone to describe it. It does not include what you were looking at.

What it never sends, and this is the part that matters:

  • Your content. Brick Calculator never transmits your wall, slab or column sizes, your prices, your estimates or the region you picked — every estimate is worked out on your phone. That data is written to your device and stays there.

  • The advertising ID — Brick Calculator 1.0. We switch this off explicitly. Brick Calculator 1.0 does not request the Android advertising ID permission, and we do not use it, so this data cannot be used to build an advertising profile of you. Brick Calculator 1.1+ is the exception, because it carries ads. It is set out in full in Section 3, including how to switch ad personalisation off. Brick Calculator 1.0 did not use the advertising ID — if you installed it before the version named here, that is the version that changed it, and we would rather say so than move the app quietly.

  • Anything to anyone else. We do not sell, rent or share these statistics, and we do not participate in data brokerage. They exist so we can improve the app.

The “More apps” screen. Our apps can show a list of our other apps on a separate screen that you open from the app’s menu or settings. To fill it, the app downloads that list and the apps’ icons from this website (itsmemomo.com) and keeps the last copy on your phone so the screen also works offline. The request carries nothing about you or your use of the app — only what any visit to a web page carries, such as your IP address — and we do not use it to identify you. Nothing is downloaded until you open the screen.

The app does request internet permission, which is what makes the statistics above possible. There is currently no in-app switch to turn these statistics off; if you would prefer not to send them, uninstalling the app stops it completely. If we add such a switch, or change what is collected, we will update this policy and the app’s Play Store data-safety details before that version is released.

3. Advertising — Brick Calculator 1.1+

Brick Calculator is free, and from version 1.1 it carries ads from Google AdMob. That is how it pays for itself, and it is the whole reason this section exists. Brick Calculator 1.0 showed none. The advertising is a single small banner along the bottom edge — there are no full-screen ads and no video ads.

  • Google AdMob is not us. It is Google’s advertising network, and it receives its own data directly from your device: your advertising ID, your device model and Android version, your approximate country from your IP address, and whether an ad was shown or tapped. What Google does with it is governed by Google’s own policy at policies.google.com/technologies/ads, not by this one. We are telling you because “we don’t collect it” would be a technically true sentence that leaves you worse informed.

  • The advertising ID, and how to switch it off. The ads are personalised, which is what the advertising ID is for. It is your switch, not ours: on your phone, Settings → Privacy → Ads lets you delete the advertising ID or turn off ad personalisation. Do it and the app keeps working exactly as before — the ads simply stop being personalised. Nothing in the app is locked behind allowing them.

  • In the EEA, the UK and Switzerland: Google’s consent form. Where an app shows Google’s consent form, your answer there decides whether the ads may be personalised, and the app keeps working the same whichever you choose. You can change it at any time from the “Privacy choices” row in the app’s settings or menu (it appears only where the form applies).

  • What an advertiser never gets. Your content — everything Section 2 says the app never sends — and the usage statistics in Section 2 are never handed to an advertiser or used to target an ad at you. We do not sell, rent or broker any of it. The ad network gets the list above and nothing more from us.

4. Children

  • Brick Calculator is not aimed at children. It is one of the apps of ours that uses the advertising ID — from version 1.1, for the ads in Section 3.

  • No purchases, no chat, no accounts — so there is nothing for a child to spend money on and no way for a stranger to contact them through the app.

If you are a parent or guardian and have a question about what your child’s device sends us, please email us — the answer is exactly the list in Section 2.

5. Data Requests

For Brick Calculator, the usage statistics in Section 2 are anonymous and are not tied to your identity, so we have no way to find “your” records in order to return or delete them — there is no account and no name attached to them. Uninstalling the app stops any further collection. If you email us for support, we use your email address only to answer you.

We update this policy whenever what the app collects changes; the date above is the date of its latest revision.
