Privacy Policy

Last updated November 7, 2026

Fin & Fern is a game for iPhone and iPad. This policy explains what happens to your information when you play it.

What stays on your device

Your game save, including your tanks, fish, their names, your rooms and your settings, is stored only on your device, in the app's own storage. The Home Screen widget and the Dynamic Island pet read a copy of your tank and fish from the same device. If you use iCloud Backup or back up your device to a computer, Apple includes your save in that backup under your own account. We never see it.

When you choose Save a backup in Settings, the backup file goes wherever you decide to send it using the iOS share sheet. When you share a fish with a friend, the fish code is made on your device and goes only where you paste it.

The game itself works fully offline. The services below connect to the internet only when your device is online.

Purchases (Apple and RevenueCat)

The optional full game purchase is handled by Apple through the App Store. We never see your payment details or your Apple Account.

We use RevenueCat to check whether the full game has been bought and to restore it on a new device. RevenueCat gives the app a random, anonymous ID and receives the App Store transaction for that ID, along with basic technical details such as the app version, device type, operating system, country or region, and the IP address the request comes from. It does not receive your name, email or Apple Account.

Optional bonus videos (Google AdMob)

Fin & Fern has no banners and no forced ads. You can choose to watch a short video for a bonus, such as extra coins or hatching an egg right away. If you own the full game, you get the same bonuses without a video.

The videos come from Google AdMob. The Google Mobile Ads SDK starts when the app opens so a video is ready if you ask for one. To show and measure ads and to prevent fraud, Google may collect information such as your device type, operating system, IP address (which gives an approximate location), how you interact with ads, diagnostic information, and an app identifier for your device. Fin & Fern does not ask for permission to track you, so your device's advertising identifier is not shared with Google.

Where the law requires it, for example in the European Economic Area and the United Kingdom, Google asks for your consent before any ads load. You can change that choice at any time in Settings > Ads > Ad privacy choices. Learn more in how Google uses information from apps that use its services and the Google Privacy Policy.

Anonymous usage stats (Aptabase)

To learn which parts of the game people enjoy, Fin & Fern sends anonymous stats through Aptabase. A stat is an event name, such as which room was opened, a few small numbers, and the app version, operating system version, device model and language. Stats contain no device identifiers, no names and nothing you typed, and they cannot be linked to you.

You can turn stats off at any time in Settings > Privacy > Anonymous stats.

How we use information

Only to run the game: unlocking the full game, showing the bonus videos you ask for, and improving Fin & Fern. We do not sell your information, and we do not use it to identify you.

Deleting your data

Deleting Fin & Fern removes your save from your device. Remember to delete any backups you made if you want those gone too. Because there are no accounts, we hold nothing that ties back to you, but you can email us and we will help with any request about the anonymous purchase record kept by RevenueCat.

Children

Fin & Fern is made for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children.

Changes

If this policy changes, the new version will be posted on this page with a new date.
