In short: The app doesn’t ask for an account and doesn’t send the birth details you enter to us. All charts are calculated on your phone, and the charts you save stay on your phone. Cities are first searched in a list stored on your phone; only if you tap “Search online” is the text you typed sent to Wikidata. Ads in the app are shown by Google AdMob; Google processes some device information for advertising under its own policy.
This policy explains what information the “Astro” mobile app (the “App”), developed by XanApps (Gökhan Eksan), uses and how.
Information you enter
To calculate a natal chart, synastry, composite, transits, a Solar Return or a Lunar Return, you enter the name (optional), birth date, birth time and birthplace of one or two people, and where needed a date and location for the transit or return. The App uses this information only to calculate the charts; all calculations happen on your device. It is not sent to us or to any server of ours.
If you enter someone else’s details (for example your partner’s or a friend’s), please make sure they are comfortable with it.
Information stored on your device
The following is stored only in your device’s storage and is not sent to us or to any other server:
- Charts you choose to save: people’s names, birth details and chart settings
- Your language setting
Unless you save a chart, the details in the form are not stored. You can delete a saved chart from within the App at any time; deleting the App removes all of this information. If your phone’s own backup feature is on (for example Android’s automatic backup to your Google account), this information may be included in your device backup; that backup is made by Google or Apple according to your account and settings.
City search (Wikidata)
When you type a birthplace, the city is first searched in a list built into the App and stored on your phone; this search doesn’t go online. If the place isn’t in the list and you tap “Search online”, the App sends the text you typed and the app language to the Wikimedia Foundation’s Wikidata service. As a technical part of delivering the request, your IP address also reaches that service. Your name, birth date and time, and saved charts are not sent. The service is operated by the Wikimedia Foundation under its own Privacy Policy.
Sharing a chart
When you tap “Share”, an image of the chart is created on your phone and passed only to the app you pick in the share menu (for example a messaging app). The image is not sent to us.
Language choice
On first launch the App checks your phone’s language and region settings, on the phone itself, to decide which language to open in. This information is not sent anywhere.
Information we don’t collect
The App doesn’t ask you to create an account. It doesn’t access your location (GPS), contacts, photos, camera or microphone. We have no analytics or tracking system of our own.
Ads (Google AdMob)
The App is free and may show a full-screen ad through Google’s advertising service AdMob when you calculate a chart. To show and measure ads, Google may collect and process:
- Your device’s advertising ID (the Android Advertising ID, or the iOS IDFA if you allow it)
- IP address and approximate location (country/city level, derived from the IP address)
- Technical information such as device model, operating system and language
- Your interactions with ads (impressions and clicks)
The birth details you enter and your charts are not shared with Google. Ad data is processed directly by Google under Google’s own policies; no information that personally identifies you reaches us. For details see the Google Privacy Policy and how Google uses information from sites or apps that use its services.
Consent and tracking permission
- European Economic Area, United Kingdom and Switzerland: Users in these regions are shown a consent form for personalised ads through Google’s consent management tool. If you don’t consent, only non-personalised ads are shown. You can change your choice later under “Ad privacy choices” in the App’s Settings screen.
- iOS: The App asks for Apple’s “App Tracking Transparency” permission to access the advertising ID. You can use the App fully even if you decline; you’ll see less personalised ads.
- Android: You can reset or delete your advertising ID in your phone’s Settings > Google > Ads (or Privacy > Ads).
Children
The App is intended for a general audience and is not directed at children under 13. We do not knowingly collect information from this age group.
Your rights
You have rights under data protection laws such as the EU General Data Protection Regulation (GDPR) where it applies. Because we don’t store your personal data, you can remove the information on your device by deleting your saved charts or the App. For requests about ad data you can use Google’s privacy tools or contact us.
Changes
We may update this policy from time to time. The current version is always published on this page and the date above changes.
