Drop Balance

Privacy Policy

Last updated: 4 August 2026

This Privacy Policy explains what information the Drop Balance puzzle game (“Drop Balance”, “the app”, “we”, “us”) processes, why, and the choices you have. Drop Balance is published by MJK APPS SRL. If you have any questions, contact us at contact@fluttech.com.

Every web address in this document is written out in full, because read inside the app these are addresses rather than working links — the in-app viewer deliberately navigates nowhere. Copy one into a browser to follow it.

1. Information we process

On your device

Your level progress, stars, streaks, pins, unlocked items and app settings are stored on your device. The game is fully playable with no network connection at all.

An anonymous identifier

The app uses Firebase Authentication to identify your save. If you play as a guest, that identity is an anonymous one: a random identifier generated by Google’s servers, carrying no email address, no phone number, no name and no social account, and linked to no account you hold anywhere else.

If you sign in with Apple or Google

Signing in is optional and the game is complete without it. Its only purpose is to attach your save to something that outlives the device, so a new phone or a reinstall can get your progress back.

If you choose to sign in, we receive from the provider and store, through Firebase Authentication:

• a provider account identifier, which replaces or is linked to the anonymous one described above;
• your email address, as released to us by Apple or Google — with Sign in with Apple you may choose Apple’s Hide My Email, in which case we only ever see a relay address, never your real one;
• your name, where the provider supplies it.

We never see and never receive your password: the sign-in happens entirely between you and Apple or Google. We use the email address only to identify the account — we do not send marketing, and the app sends no email at all. Your email address is never published anywhere. Your name is used as your display name on the public boards, so that a board reads as people rather than as codes — you can change it to anything you like, or leave the boards altogether, under Settings → Account. See Public boards below.

You can sign out at any time under Settings → Account → Sign out, and delete the account outright under Settings → Account → Delete account — see section 5.

Cloud copy of your progress

A copy of your game progress (stars per level, daily-challenge results, unlocked worlds, endless best, pins, XP and owned cosmetic items) is mirrored to Cloud Firestore under your anonymous identifier. It exists so a reinstall or a corrupted local save does not cost you your progress. It contains no name, no email address and no contact details of any kind — only your game state and the days you played.

Public boards

Drop Balance has public leaderboards for the daily challenge and for Endless mode, and your results stand on them by default — competing with other players is part of the game rather than a feature to go and find. A board row contains:

• a display name — either one you choose, or a generated handle of the form BALANCER-XXXX;
• your score for that board (stars and elapsed time for the daily; height for Endless);
• your anonymous identifier;
• the app version that submitted the row;
• the time of submission.

Those rows are readable by other players of the game — that is what a public board is. Nothing else about you is on them: not your email address, not your progress, not the days you played.

Your display name is your Apple or Google account name when you signed in with one, and otherwise a handle the game generates from your anonymous identifier (something like Steady Pivot.04). Either way you can replace it with anything you like under Settings → Account → Board name, and the new name is applied to the rows you already have up.

Coming off the boards. Standing on them is part of playing Drop Balance, so there is no separate switch for it. What there is instead is Settings → Account → Delete account, which deletes your board rows along with everything else filed under your account, immediately and permanently. If you want a row removed without deleting your account — an older daily board, say — write to contact@fluttech.com and we will remove it.

Usage analytics

We use Firebase Analytics (provided by Google LLC / Google Ireland Ltd) to understand, in aggregate, how the game is played so we can improve it. The events we record are about the game, not about you: opening the app, starting, completing and failing a level, placing an object, using undo or a hint, starting and completing the tutorial, starting and completing the daily challenge, finishing an Endless run, unlocking an achievement, spending pins, opting into the boards, submitting to a board and viewing one, watching a reward ad or failing to find one to watch, and the outcome of the ad-consent question described below. Firebase attaches basic technical context of its own, such as app version, device model, operating-system version and coarse region, tied to a Firebase-generated app-instance identifier.

You can switch usage analytics off at any time in Settings → Privacy → Share anonymous analytics. When it is off, no analytics events are collected. Where the consent form described under Advertising applies — the EU/EEA, the UK and Switzerland — analytics is additionally held back until you have answered that form, and then follows the answer you gave it. We never use these events to advertise to you, and we never sell them.

Advertising

Ads are how Drop Balance pays for itself, together with the one optional purchase described in section 2 — which removes the first two of the three placements below. There are three placements, and only three:

• sponsored cards inside the lists on the menu and progress screens — Worlds, Daily, Standings and Me, and the Standings boards, Achievements, Records, Inbox and Weekly Rhythm screens you open from them. Each one is marked SPONSORED, sits in its own frame, and is never dressed as one of the rows around it. There is none in the shop, in settings, or on the level-select screen.
• a small banner above the board while you play a campaign level or the daily challenge. It sits in the strip between the objective and the play area, where no part of the game is played: it never covers the board, the shape tray or any button, and it never appears over a game in progress — it is there when the level opens or not at all. Zen and Endless have no banner, and neither does the level-select screen or anything between levels.
• an optional reward clip. It exists in one place — a card in the shop offering in-game pins in exchange for watching one — and it only ever starts because you tapped that card. Nothing in the game is locked, slowed or withheld until you watch one, and you can watch at most two a day. What it pays is in-game pins, which have no monetary value.

There are no ads between levels, no ads when the app opens, and no ad that interrupts a game in progress. A short list in our own database can switch ads off for individual installs — our test devices, for example; checking it sends nothing but the anonymous identifier already described, and records nothing.

Ads are supplied by Google AdMob (provided by Google LLC / Google Ireland Ltd). To deliver, frequency-cap and measure them, AdMob may process information about you and your device, including the device’s advertising identifier, IP address (which Google may also use to measure and personalise ads, including across the EEA, the UK and Switzerland), the approximate (coarse) location derived from that IP address, device and operating-system details, and basic information about how you interact with the ads. Some of this processing is considered “tracking” under Apple’s App Tracking Transparency framework. Where our AdMob and Firebase accounts are linked, Google also reports ad impressions and the revenue they earn into the aggregate analytics described above.

Your choice (consent). Where required by law — including the EU/EEA, the UK and Switzerland — we show a Google-provided consent form before any personalised ads are served, and no ad is requested until it has been answered. You can allow personalised ads, or choose to receive only non-personalised ads. On iOS, Apple’s separate App Tracking Transparency prompt is asked first, unless your device settings already answer it on every app’s behalf. If you decline tracking or personalisation you will still see ads, but they will not be personalised based on a profile of you — and the game itself plays exactly the same either way.

You can review or change that choice at any time in Settings → Privacy → Ad privacy choices. That row appears where the consent form applies to you.

The analytics switch does not govern ads. Turning off Share anonymous analytics stops the events described above; it does not stop ads, and it is not how ad personalisation is chosen. Ads are governed by the consent form, by your App Tracking Transparency answer on iOS, and by your device’s own advertising settings.

For Google’s own account of what it does with this data, see policies.google.com/technologies/partner-sites, policies.google.com/technologies/ads and policies.google.com/privacy.

Crash reports

If the app breaks, Firebase Crashlytics (provided by Google LLC / Google Ireland Ltd) sends us a report so we can fix it. A report may contain your device model, operating-system version, app version and a technical stack trace of the failure, together with an identifier Crashlytics generates for the installation so that repeated crashes on one device count as one bug rather than many. It is used to diagnose and fix problems and for nothing else: not to identify you, not to advertise to you, and it is never sold.

You can switch crash reports off in Settings → Privacy → Share crash reports. It has its own switch, separate from the analytics switch and from your ad choices, because a stack trace and a usage statistic are different things and deserve different answers.

Feedback you send us

If you use Settings → Send feedback, we store the message you write, together with your app version and your anonymous identifier, so we can understand the problem and — where the message tells us how — follow it up.

Name reports

If you report a board row for an inappropriate name, we store the reported row, the reported name and identifier, and your anonymous identifier, so we can review it. Reports are readable only by us.

2. What we do not collect

• No payment details. The app offers one optional purchase, and Apple or Google take the payment, hold the record of it and tell the app only whether you own it. We never see, receive or store a card number, a billing address or any other payment information. The purchase is filed against your App Store or Google Play account rather than your Drop Balance account, so deleting your account here neither reaches nor refunds it. There is no currency you can buy — pins are earned only.
• No passwords. Signing in with Apple or Google happens between you and them; we never see, receive or store a password. There is no Drop Balance password to create or lose.
• No phone number, and no email address unless you choose to sign in with Apple or Google, as described in section 1.
• No contacts, no photos, no microphone, no camera.
• No location from your device. The app never asks for location permission and never reads your device’s location. The only location involved is the coarse one AdMob derives from your IP address, described under Advertising above.
• No notifications. The app sends none, so it collects nothing in order to send them.
• No device identifiers beyond the ones described above: the anonymous identifier, the app-instance and installation identifiers Firebase attaches to its own analytics events and crash reports, and the advertising identifier AdMob uses to serve and measure the ads.
• Nothing you write to another player. Drop Balance has no chat and no messaging. A display name and a score on a public board is the only thing about you that other players ever see.

3. Service providers

We rely on the following providers to run these features:

• Google Firebase — Authentication (the anonymous identity, and Apple or Google sign-in if you use it), Cloud Firestore (cloud save, boards, feedback, reports), Crashlytics (crash reports) and Analytics, provided by Google LLC / Google Ireland Ltd. See firebase.google.com/support/privacy and policies.google.com/privacy.
• Google AdMob — serves the sponsored cards, the play-screen banner and the optional reward clips, and presents the consent form through Google’s User Messaging Platform. Provided by Google LLC / Google Ireland Ltd. See support.google.com/admob/answer/6128543, and the three Google policy addresses printed under Advertising above.
• Apple — if you use Sign in with Apple, the sign-in is performed by Apple and governed by Apple’s own privacy policy. See apple.com/legal/privacy.
• Google Fonts — the app loads its typefaces from Google’s font servers (fonts.gstatic.com); this involves a request to Google that may include your IP address and device information, per Google’s policies.

Google AdMob is our only advertising network: there is no mediation, no second ad network, no attribution SDK of our own and no analytics provider other than Firebase. On iOS the app does declare Apple’s SKAdNetwork identifiers for the ad networks that buy through AdMob. That is Apple’s own privacy-preserving measurement framework: it lets Apple tell an advertiser that an install followed one of their ads, in aggregate and after a delay, without giving them an identifier for you or letting us see anything at all. Apart from the advertising data described above, we share your data with no third party for that party’s own purposes.

4. Sharing and selling

We do not sell your data, and we never have. We do share the information described under Advertising with Google AdMob, so that it can serve, cap and measure the ads that keep the game free; how much of it may be used to personalise those ads is governed by the consent choices you make. Apart from that, we do not share your data with third parties for their own purposes. The only information about you that other players can see is the display name and score on a public board row.

5. Keeping and deleting your data

• Your whole account: Settings → Account → Delete account deletes your Firebase Authentication record — including the email address and name released by Apple or Google, if you signed in — together with your cloud save and your rows on the current public boards. It is immediate and cannot be undone. This works for a guest identity too.
• Board rows only: there is no in-app switch for this — the boards are part of the game rather than a feature you turn on. Write to contact@fluttech.com and we will remove the rows you name.
• On your device: deleting the app removes your local progress and abandons the anonymous identifier — it is stored nowhere else on your device, so a fresh install starts a new one.
• Everything on our side: email contact@fluttech.com and we will delete your cloud save, any remaining board rows and any feedback tied to your identifier. We action such requests within 14 days. To let us find the right records, send the request from the app’s feedback form, or include the identifier shown in the app.
• Older daily boards close — once a day has passed, no new row can be written to it — but the rows already on them are kept. The in-app removal above cannot reach them, so if you want those gone as well, email us and we will delete them.
• Crash reports and advertising data: neither is filed under your anonymous identifier, so there is no record of yours for us to look up — advertising adds nothing to our own servers at all. You can stop new crash reports with the switch in Settings, and what Google holds for advertising follows your consent choices and your device’s own advertising settings, where the advertising identifier can also be reset.

6. Your rights (EU/EEA — GDPR)

You have the right to access, correct, export and erase your personal data, to restrict or object to processing, and to lodge a complaint with your local data-protection authority. The quickest way to exercise the erasure right is Settings → Account → Delete account, which needs no request and no waiting; the deletion email above covers anything it cannot reach.

Our legal bases for processing are: providing the features you ask for (the anonymous identity, cloud save, and the boards you opted into) under contract; our legitimate interest in diagnosing crashes, in understanding in aggregate how the game is played, in keeping the boards free of abuse, and in showing non-personalised ads so the game can be free to play; and your consent — for personalised ads and the tracking they involve, which you give or refuse in the consent form and can change at any time in Settings → Privacy → Ad privacy choices, and for the public boards and usage analytics, which you can withdraw at any time in Settings.

7. Children

Drop Balance is a general-audience puzzle game and is not directed at children below the age of consent in their country. We do not knowingly collect personal data from children. The app asks nobody for a contact detail, and it has no chat, messaging or friend system; the only name and email address it can ever hold are the ones Apple or Google release when an adult chooses to sign in. Display names are checked against a filter and a limited character set before they can be published, and a player can leave the boards at any time. It does show ads, which are served by Google AdMob under Google’s own advertising policies and the consent choices described in section 1. If you believe a child has provided us with personal data — for example inside a feedback message — contact us and we will delete it.

8. Security

Data is transmitted over encrypted connections (HTTPS/TLS). Cloud data is protected by Firebase security rules so that an identity can only write its own records: your cloud save and your board rows are writable by you and nobody else, and feedback and reports can be created but never read back by any client.

9. Changes to this policy

We may update this policy from time to time. We will update the date at the top and, for significant changes, note it in the app.
