Privacy Policy

Sinastri ✨

Two birth charts, one shared sky

Last updated: October 3, 2026

Türkçe

In short: The app doesn’t ask for an account and doesn’t send the birth details you enter to us. Charts and compatibility reports are calculated on your phone, and reports you save stay on your phone. When you search for a birth place, only the text you type is sent to OpenStreetMap’s place search. Ads in the app are shown by Google AdMob, and Google processes some device information for advertising under its own policy.

This policy explains what information the “Sinastri” mobile app (the “App”), developed by XanApps (Gökhan Eksan), uses and how.

Information you enter

To create a synastry report, you enter a name, birth date, birth time (optional) and birth place for two people. The App uses this information only to calculate the birth charts and the compatibility report, and all calculations are done on your device. It is not sent to us or to any server of ours.

If you enter another person’s details (for example a partner or a friend), 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 never sent to us or to any other server:

The details in the form are not stored unless you save a report. You can delete a saved report in the App at any time, and deleting the App deletes all of this information. If your phone’s own backup is turned 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 under your account and settings.

Birth place search (OpenStreetMap)

When you type a birth place, the App sends the text you typed and your App language to the Nominatim place search service of the OpenStreetMap Foundation, to find the city and its coordinates. Your IP address also reaches the service as a technical part of delivering the request. Your name, birth date and time, and saved reports are not sent. This service is operated by the OpenStreetMap Foundation under its Privacy Policy.

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.

Advertising (Google AdMob)

The App is free and, after a report is created, may show a full-screen ad through Google’s advertising service, AdMob. To show and measure ads, Google may collect and process:

The birth details you enter and your reports are not shared with Google. Advertising 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

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 Turkey’s Personal Data Protection Law No. 6698 (KVKK) and, where applicable, the EU General Data Protection Regulation (GDPR). Since we don’t store your personal data, you can remove the information on your device by deleting your saved reports or the App. For requests about advertising 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.
