Privacy Policy — Nile Fields: Rope Stretchers 🪢🌾

Last updated: 19 September 2026

Nile Fields: Rope Stretchers itself does not collect, store, transmit, or share any personal information. It is a two-player (same-device) and solo educational area-and-perimeter game whose gameplay runs entirely offline on your device. The app is free, has no in-app purchases, and is supported by advertising, which is described in full below.

Information we collect

None. The app has no accounts, no sign-in, and no analytics of our own. It does not request your name, email, contacts, location, photos, or any other personal data.

Advertising (Google AdMob)

The iOS app shows a single banner advertisement, supplied by Google AdMob. It appears on the start screen, the win screen, and beneath the pause, help and language panels, and is hidden while a round is being played, so it never covers the field.

• Non-personalised. Every request is made as a non-personalised ad request, so ads are based on the general context rather than any profile of the player.
• Child-directed. Because the audience is children, every request is tagged for child-directed treatment and for users under the age of consent. No advertising identifier is transmitted, and the app never presents Apple's App Tracking Transparency prompt because it does not track you.
• General audiences only. Ad content is restricted to Google's "General" maximum content rating.
• Not used for cross-app tracking. We do not link any advertising data to a person, and we receive no report identifying any individual.

To deliver an ad, Google receives technical information such as a device type, a coarse region and the fact that an ad slot was shown. See Google's Privacy Policy and How Google uses information from sites or apps that use our services.

Your choice. Where consent is required (for example in the European Economic Area and the UK), Google's User Messaging Platform asks before any ad is requested, and no advertising SDK is started until that choice allows it. You can change your choice at any time with the Privacy and cookie settings link on the app's start screen.

Offline. With no network connection the app simply shows no advertisement. It raises no error and remains completely playable.

What the app does not collect

No accounts, no sign-up, no email address, no contacts, no location, no photos, no microphone or camera access, no personal information of any kind, and no external links other than this policy and the privacy controls described above.

Data storage

Game state (the field, each surveyor's claimed squares, whose turn it is, your chosen language and settings) exists only in memory while you play and is discarded when the app closes. Google's advertising and consent components store their own settings on the device, including your recorded consent choice.

Children's privacy

Nile Fields is an Education app rated 4+ and is suitable for children. It is not published in Apple's Kids Category and is not a "Made for Kids" app. We collect no personal information from anyone, including children under 13, and all advertising is configured as child-directed, non-personalised and limited to general-audience content, as described above. Parents who prefer to limit advertising further can do so in the device's own settings.

Changes to this policy

If this policy ever changes, the updated version will be posted at this URL.
