CoopBook — Privacy Policy
Last updated: September 30, 2026
CoopBook is made by TCAR Studio. We built it to work entirely on your device.
What we collect
Nothing that identifies you. CoopBook does not require an account. Everything you enter, including your flocks, hens, egg counts, feed and expense records, egg sales, hatch records, notes, reminders and photos, is stored only on your device. We never upload it, we cannot see it, and we do not sell it.
Photos
If you add a photo of a hen or a flock, CoopBook reads only the picture you choose with the system photo picker and keeps a copy inside the app on your device. Nothing is sent anywhere.
Advertising (free version on Android and iOS only)
The free version shows a banner ad on the flock list, served by Google AdMob. Ads never appear on the Collect screen. AdMob may collect device identifiers (such as the advertising ID) and coarse usage data, for example ad interactions, to serve and measure ads. We request non-personalized ads by default, and CoopBook does not track you across other companies' apps and websites. In the European Economic Area and the United Kingdom you may see a consent message before any ad is loaded. You can remove ads permanently by buying CoopBook Pro. When Pro is active, the advertising SDK is not loaded. Google's policy: https://policies.google.com/technologies/ads
Purchases
CoopBook Pro is a one-time in-app purchase processed by Apple (App Store) or Google (Google Play). We receive only a confirmation that a purchase happened. We never see your payment details. The Windows version has no ads.
Reminders and notifications
Reminders are scheduled locally on your device. No notification data leaves your device.
Backups and exports
If you export a CSV or PDF file or create a backup (Pro), the file is created where you choose, for example your own cloud drive or email. We do not have access to it.
Network use
Apart from ads (free version) and purchase processing by the app store, CoopBook makes no network requests.
Children
CoopBook is not directed at children under 13 and we do not knowingly collect data from them.
Your rights
Because we hold no personal data about you, there is nothing for us to access, correct or delete on our side. Deleting the app removes all data from your device, so export a backup first if you want to keep it. For data handled by Google AdMob, see Google's privacy policy at https://policies.google.com/privacy.
Changes
If anything changes, we will update this page and the "Last updated" date.
