Effective 6 November 2026
This privacy policy applies to the Tiny Observatory app for iPhone and iPad (the “Application”). The Application is made by Daniel Ridzoň, a sole trader in the Czech Republic trading as Ridzon Games (the “Service Provider”), who is the controller of the personal data described here. You can reach the Service Provider at support@ridzongames.com.
Location. The Application uses your device’s location to draw the real sky above you and to estimate how dark your sky is, from a map bundled in the Application. Your location is used only on your device. It is never sent to the Service Provider or to any third party.
Camera. The camera is used only to place your observatory in augmented reality on your desk. No image or video is recorded, stored or sent anywhere.
Photos. If you choose to save a plate to your photo library, the Application adds that image to it. It never reads your photo library.
Your game. Your progress is saved in a file on your device. It contains the location you played from, because the sky is calculated from it. The Service Provider never receives this file unless you send it yourself (see below).
The Application uses two Google services:
Neither service receives your name, contact details, precise location or game data. Both are operated by Google, which processes this data on the Service Provider’s behalf, and may process it outside the European Economic Area under Standard Contractual Clauses. Their privacy terms:
The legal basis for this processing is the Service Provider’s legitimate interest in keeping the Application working and learning how it is used (Article 6(1)(f) GDPR). Where the law requires your consent for analytics, the Application will ask for it before collecting.
If you email the Service Provider, for example with a question, feedback or your save file, the Service Provider receives what you send, including your email address. A save file includes the location you played from. This information is used only to answer you and to improve the Application, and is deleted when it is no longer needed for that.
Under the GDPR you have the right to access, correct and delete your personal data, to restrict or object to its processing, and to data portability. To exercise any of these rights, email support@ridzongames.com. You also have the right to complain to a data protection authority; in the Czech Republic this is the Office for Personal Data Protection (Úřad pro ochranu osobních údajů, uoou.gov.cz).
If you are a California resident, you have the right to know what personal information is collected, to have it deleted, and not to be discriminated against for exercising these rights. The Service Provider does not sell or share personal information.
Uninstalling the Application stops all further collection.
The Application is a game about astronomy, suitable for teenagers and adults. It does not ask anyone for personal information, and collects only the anonymous usage and crash data described above. If you are a parent or guardian and want data about your child’s device deleted, email support@ridzongames.com.
Data sent to Firebase is encrypted in transit. The Service Provider has no servers of its own and keeps no copy of your game.
The Service Provider may update this policy, for example when the Application gains new features. The updated policy will be posted on this page with a new effective date. Material changes will be announced in the Application where the law requires it. Previous versions are available on request.
