Tumbledown!

Privacy Policy

Last updated: 27 October 2026 · applies to Tumbledown! for iPhone from version 1.1, and to this website

The short version

From version 1.1, Tumbledown! shows ads: optional videos that you choose to watch for a reward, and, from level 20, an occasional ad between levels. The ads come from two advertising partners, Google (Google AdMob) and Unity (Unity Ads, which offers its ads through Google AdMob). Their code in the app collects information about your device and the ads you see, to show and measure ads. If you allow it when iOS asks, they may also use your device's advertising identifier to show you more personal ads. The game starts their code when you first open it, on its main screen before you play a level, with the privacy questions first; Google's part of it may already contact Google when the app opens (section 3).

We, the developer, have no server and no account system. The game's own code sends nothing anywhere (iOS's anonymous ad attribution aside, section 3), and we receive no personal data about you from the game. Your progress stays on your iPhone. Purchases are handled by Apple.

Your choices: answer the tracking question as you like (it changes nothing in the game) and change it any time in your iPhone's Settings; in Europe, the UK and Switzerland, change your ad consent in the game's Settings → Privacy Choices; buy No Ads to remove the ads between levels. See your choices.

1. Who we are

Tumbledown! is made by Mohannad Abdelkarim, an independent game developer based in Egypt ("we", "us"). We are responsible for the app and this website. You can reach us at tumbledown.support@gmail.com.

2. What the app keeps on your iPhone

To remember your game, the app saves a small file in its own storage on your device. It contains:

The game sends none of this to us, and we cannot see it. Deleting the app deletes it. Your iPhone's own backups (iCloud or a computer) may include it, as they include other app data; Apple handles those backups under its own privacy policy. The advertising partners' code also keeps some data on your device, such as your consent choices and identifiers it uses for ads (section 3).

3. Advertising

Where the ads are. Videos are optional: when you run out of balls you can watch one for +5 balls (or pay coins as before), and when you are out of lives you can watch one for +1 life. You only get the reward after the video. From level 20, an ad sometimes plays between levels (after you leave the result screen), never during a level. There are no banner ads.

When the ad code runs. The partners' code is built into the app. The game starts it the first time you open version 1.1 or later (on a new install, or after updating from 1.0), on the game's main screen after the start screen, before you play a level. Then, in this order: Google's consent code asks Google's servers which privacy questions apply where you are (this shows Google your IP address) and shows them; iOS asks the tracking question (section 4; not if you refused in Google's consent form); and only then, and only if your answers allow ads to be requested, Google's ad code starts and asks for ads. Google's ad code starts Unity's. After that, the game does the same each time you open the app, so that a video is ready when you want one. iOS asks the tracking question only once; if it could not ask yet (for example, because tracking requests were off in your iPhone's Settings), it may ask when you next open the game.

Because it is built in, Google's code also does some work of its own each time the app opens, even before the game starts it and before the privacy questions: it prepares its own storage on your iPhone and it may connect to Google's servers. In our own tests of a new install, it looked up the internet address of a Google server (www.google.com) as the app opened. Like any internet connection, a connection to Google shows Google your IP address. This happens whether or not you ever see an ad, also with No Ads. No code in the app can read your advertising identifier (IDFA) unless you allow tracking: iOS gives it to an app only after you tap Allow.

Our partners. The ads are run through Google AdMob, a service that lets several advertising companies offer an ad for each slot. The partners whose code is in the app are:

Through Google AdMob, other advertising companies can also bid to show an ad. In Europe, the UK and Switzerland, Google's consent form lists the companies involved.

What the partners collect. As the partners describe it in their own documentation and policies, their code may collect:

What they use it for. To choose and show ads, to make sure an ad is not shown too often, to count views, taps and installs and pay us for them, to prevent fraud, to fix and improve their services, to comply with the law and, only if you allow tracking (and, in Europe, the UK and Switzerland, consent), to show you ads based on your activity in other companies' apps and websites. Google also declares that its ad code may use these data for a developer's own advertising (for example, to measure ads that a developer runs for its own app); we do not advertise the game through Google today. The partners use the data under their own privacy policies (linked above), as independent companies.

What we receive. Only totals in the partners' dashboards, such as how many ads were shown per day, country and ad type, and what they earned. We cannot see who you are.

If you installed the game from an ad. If an ad for Tumbledown! led you to install it, Apple's privacy-preserving ad attribution (SKAdNetwork and AdAttributionKit, built into iOS) may tell that ad's network, without identifying you, without the tracking permission and only after a delay, that the ad led to an install, along with a rough measure of play set by the game (how far you got, whether you watched a video for a reward, whether you bought something).

We only work with ad partners whose terms require them to protect the data they receive through the app with the same or equal protection as described in this policy and as Apple's App Store rules require.

4. Your choices

5. United States: your state privacy rights

Some US state laws (for example in California, Colorado, Connecticut, Virginia and Texas) give you the right to know what personal information is collected about you, to have it deleted or corrected, and to opt out of its "sale" or "sharing" for targeted advertising. We do not sell personal information for money, and the game sends us none. When our ad partners use device identifiers from the app for personalised ads, some of these laws may treat that as "sharing" or a "sale". To opt out:

We will never treat you differently in the game for using any of these rights.

6. No Ads and other purchases

7. Other Apple features the app uses

8. Children

Tumbledown! is a game for a general audience. It is not directed at children under 13 and is not in the App Store's Kids category. We do not knowingly collect personal information from children, and our ad partners say they do not knowingly collect children's data or show children personalised ads through their services. We ask the partners for ads suitable for the game's 9+ rating: Google's "PG" maximum ad content rating (asked for in every ad request too) with dating, sexual, gambling and social casino ads blocked, and Unity's age limit, which blocks ads for apps rated 13+ or higher (casino games included). The app does not tell the partners that it is directed at children, because it is not. On Apple Accounts of people under 18, iOS does not let apps ask to track, so the advertising identifier is not available to the partners. If you are a parent and believe your child's data has reached us or our partners, contact us: we will delete anything we have (we normally have nothing) and help you send a deletion request to each partner.

9. Reporting an ad

If an ad is inappropriate, broken or not suitable for the game's age rating, use the game's Settings → Report an Ad. It opens an email to us in your Mail app, already filled in with the details of the last ad shown (when it was shown, its type, the ad network, Google's reference number for the ad and the ad unit) and your app version, iOS version and iPhone model. Nothing is sent unless you press Send. We use the report only to find and block the ad with the ad partner, and we handle the email as described in section 12.

10. How long data is kept

We keep no data from the game. The data in section 2 stays on your iPhone until you delete the app. The ad partners keep what they collect for the periods set out in their policies (Google, for example, says it anonymises advertising data in its server logs by removing part of the IP address after 9 months: How Google retains data). Emails are covered in section 12.

11. Where data is processed

The ad partners are based in the United States (Google also through Google Ireland Limited for Europe) and process data there and in other countries. They describe how they protect data transferred out of Europe and the UK (for example with the EU Standard Contractual Clauses) in their policies.

12. If you email us

If you write to us (including through Report an Ad), we receive your email address and your message. We use them only to answer you and, for ad reports, to have the ad blocked. We do not share them, except the ad details with the ad partner concerned, and we keep them only as long as needed to help you. You can ask us to delete them at any time.

13. This website

This website has no ads, no cookies, no analytics and no trackers, and loads nothing from other sites. It is hosted on GitHub Pages; GitHub may record technical information such as IP addresses to run and protect its service, as described in GitHub's privacy statement.

14. Your rights

Depending on where you live (for example under the GDPR in Europe and the UK), you may have the right to access, correct or delete your personal data, to object to or restrict its use, to withdraw consent at any time (section 4), and to complain to your data protection authority. Because the game sends us no personal data, we hold nothing about you from the game that we could show, correct, export or delete: your game data is under your control on your device, and the ad partners hold their own data (sections 3 to 5 show how to reach them). For emails you sent us, you can ask us to see or delete them.

15. Changes to this policy

We will post any change on this page and update the date at the top. If a change affects how the app handles your data, we will update the App Store privacy information at the same time and the app will ask for your permission wherever the law or Apple requires it. Version 1.0 of the app had no ads and no advertising code: the advertising sections of this policy apply from version 1.1.
