Privacy Policy

Effective 25 August 2026 · applies to Overfill for iOS, version 1.0

The short version

Your save stays on your device. There is no account, no sign-in, and no server holding a copy of your game.
Overfill is free and carries ads, and the ads are the part that collects. They are served by Google, whose SDK is the only third-party code in the app.
Before any ad loads, you are asked. Where the law requires a consent form you get one, and iOS asks separately whether the app may track you.
Declining tracking does not break the game and does not remove the ads. It makes them non-personalised.
The developer never receives your data. Everything below is Google receiving it, or nobody receiving it.

Two halves, and they are worth keeping apart

Most of this page is about advertising, so it is easy to come away with the impression that Overfill is sending your game somewhere. It is not. The app has two separate halves and only one of them touches the network:

The game itself — the bar, your coins, your five upgrades, your banked multiplier. This half has no networking code of its own at all. It cannot send anything anywhere.
The advertising — Google's Mobile Ads SDK, embedded so the game can be free. This half does reach the internet, and it does collect. What it collects is set out in full below.

Nothing crosses between them. Google is not sent your save, your coins, your upgrades or your multiplier, because the game half has no way to hand them over and the ad half never asks.

What the game itself stores

This is the complete list, not a summary of a longer one. All of it is on your device:

What	Where it lives	Leaves your device?
Your game — how full the bar is, your coins, the level of each of the five upgrades, your banked multiplier, and when the app last saw you	A small save file in the app's own Application Support folder	No
Your settings — whether reminders are switched on, and whether you have bought Remove ads	A handful of values in the app's own preferences	No
Your two reminders, if you turned them on	Scheduled with iOS on your device, on a timer, with no server involved	No

There is no name, no email address, no account, no contacts, no photos, no health data, no precise location, and no record of your play sent anywhere by the game. The reminders are local notifications on a timer — Overfill never registers for push, so there is no device token and nothing for a server to send to, because there is no server.

Advertising: what Google collects

Overfill is free because it carries ads. They are served by Google AdMob, using Google's Mobile Ads SDK, which is the only third-party code in the app. Google's own privacy manifest declares what that SDK collects, and Overfill's declaration is copied from it rather than guessed at. Here it is in plain English:

What Google collects	Tied to you?	Used to track you across other apps?	What for
Device identifier — your device's advertising ID	Yes	Yes, and only if you allow it	Advertising and measurement
Advertising data — which ads you were shown, and whether you interacted	Yes	No	Advertising and measurement
Product interaction — that an ad was requested, shown, or dismissed	Yes	No	Advertising and measurement
Coarse location — an approximate region worked out from your IP address	Yes	No	Serving regionally appropriate ads
Performance data — how the SDK itself performed	No	No	Diagnostics
Crash data — crashes inside the SDK	No	No	Diagnostics
Other diagnostic data	No	No	Diagnostics

Coarse means coarse. Overfill contains no location code and asks iOS for no location permission of any kind — you will never see a location prompt from this app. The row above is Google inferring an approximate region from the IP address your connection already reveals to every server it reaches. It is not GPS and it is not your address.

Google's handling of this data is governed by Google's own policies, not by this one. The two worth reading are Google's Privacy Policy and how Google uses data from apps that use its services.

What you are asked, and when

Nothing loads before you are asked. On first launch, in this order:

A consent form, where the law requires one. If you are in a region covered by rules like the EU and UK's, Google's consent tool presents a form asking what the ads may do. Your answer decides whether personalised ads may be served, and whether ads may be requested at all. Outside those regions the form does not appear, because there is nothing to ask.
iOS's own tracking prompt. Separately, iOS asks whether Overfill may track you across other companies' apps and websites. This is Apple's prompt, not the app's, and iOS shows it once.

Only after both have resolved does the ad SDK start at all. That ordering is deliberate and enforced in the app's own startup code: no consent, no SDK.

If you say no

Saying no to the tracking prompt is a normal, fully supported way to play. The game is identical. Google's SDK then has no advertising identifier to use, so the ads it serves are non-personalised — chosen from context rather than from a profile of you. It does not mean the ads stop, and this page would be misleading if it implied otherwise. If you declined and later change your mind, iOS holds that switch in Settings › Privacy & Security › Tracking.

Changing your consent answer later

If a consent form was shown to you, Overfill's own Settings screen carries a Privacy options row that reopens it, so you can change your answer whenever you like. The row is only there if the form applies to you — in regions where no form is required there is nothing behind it, so the app does not show a button that would do nothing.

The three kinds of ad, and where each one can appear

The opt-in one. A button that says what it gives you before you tap it: watch, and the bar runs at double for an hour. Nothing happens unless you choose it.
The unprompted one. A full-screen ad between moments of play, and it is rationed in the app's own code rather than by a setting: none in the first ten minutes of a session, at least five minutes between any two, and no more than three in a session.
There is no third kind. No banner sitting on the play screen, no ad on launch, and nothing that appears while the bar is filling.

Buying Remove ads — what it does and does not do

Overfill sells one thing: a single non-consumable purchase that removes ads, handled entirely by Apple. The developer never sees your payment details, your Apple Account, or your name; the app is told only whether the purchase exists.

Being precise, because the honest answer is narrower than the button name. The purchase stops the unprompted full-screen ads — permanently, on every device signed into your Apple Account, restorable with Restore purchases. It does not uninstall Google's SDK, and it deliberately leaves the opt-in ad available, so an owner who wants the double-rate hour can still choose to watch one. That means Google's SDK is still present after the purchase, and what it may collect is decided by your consent and tracking answers above — not by whether you have paid. If you want the collection reduced, the tracking prompt and the privacy options are the controls that do it; the purchase is not one of them.

The App Store privacy label

Overfill's product page does not read "Data Not Collected", and it should not. The label lists the seven types in the table above, marks the four that are tied to you, and marks the device identifier as used to track you. That label is generated from the same declaration the app ships in its own privacy manifest, which in turn is copied from Google's — so the label, the manifest and this page all say the same thing on purpose.

The app also declares the one Apple-designated API it uses on its own account: reading and writing its own preferences, for the settings in the table above and nothing else.

What Overfill does not do

No account, login, or profile. The game never asks who you are.
No analytics or crash-reporting SDK of the developer's own. The diagnostic rows above are Google's SDK reporting on itself.
No leaderboards, no friend lists, no chat, and nothing you write shown to anyone else.
No precise location, contacts, photos, camera, microphone, health, or calendar access — none of these are requested and no code in the app reads them.
No share sheet and no photo-library access, so there is no path by which a screenshot or a summary of your game could be handed to another app.
No server operated by the developer, so no backups, logs, or copies of your game exist anywhere off your device.
No mailing list, because there is no address to put on one.
Nothing randomised for sale, no loot box, and no currency bought with money.

Children

Overfill is not directed to children, is not marketed to children, and is not in the App Store's Kids Category. It carries third-party advertising and an in-app purchase, which is why it is not suitable for that category and why it is not offered there. The developer does not knowingly collect personal information from children. If you believe a child has used this app in a way that concerns you, the fastest complete remedy is deleting the app, which erases everything it stored; there is no account to close and no server-side record to request.

Your controls, in one place

What you want	Where
Stop ads being personalised to you	iOS Settings › Privacy & Security › Tracking, or decline the prompt when it appears
Change the consent answer you gave	Privacy options, in Overfill's own Settings screen (shown where a form applies)
Stop the unprompted full-screen ads	The Remove ads purchase, in Overfill's Settings screen
Stop the reminders	The Remind me toggle in Overfill's Settings, or iOS Settings › Notifications. They are off until you turn them on.
Erase everything the app stored	Delete the app. That removes the save, the settings and the reminders with it.

Requesting or deleting your data

There is no developer-held copy of anything to hand over or erase — no account exists, and your game lives only on your device. Deleting the app is a complete erasure of everything Overfill saved.

For the advertising data in the table above, the holder is Google, and Google's own controls are the ones that reach it: My Ad Center for what Google uses to choose your ads, and the Google Privacy Policy for the rest. Turning off the tracking permission stops your advertising identifier being shared in the first place, which is the more direct remedy.

If you use iCloud or Finder device backups, iOS may include the app's files in your own backup. That backup is yours, under your Apple Account and Apple's privacy policy; the developer has no access to it.

Changes to this policy

If Overfill's behaviour changes in a way that affects this policy, the policy is updated here with a new effective date before that change ships. In particular, if any future version added an analytics SDK, a server, an account, or any collection by the developer rather than by Google, it would be stated here explicitly and reflected in the App Store privacy label at the same time.
