PRIVACY POLICY
Last Updated: 08/31/2026
This Privacy Policy ("Policy") explains how Eisberg Labs d.o.o. za proizvodnju i usluge ("we", "us", or "our") collects, uses, and protects information from users ("you") of the Gate 64 mobile application and related services (collectively, the "App" or "Services").
We are the Data Controller under the EU General Data Protection Regulation (GDPR) for personal data processed through the Services.
1. WHO WE ARE
Eisberg Labs d.o.o. za proizvodnju i usluge Celjska ulica 3 OIB: 44452565653 Website: https://www.eisberg-labs.com Email: support+gate64@hexagramdreams.com
2. INFORMATION WE COLLECT
a. App - Anonymous Use
You can use the Gate 64 app without signing in. When you use the app without an account, we and our service providers may automatically collect certain technical and behavioral data, including:
- Device type and operating system
- Unique device identifiers (such as the Google Advertising ID on Android)
- IP address (used for approximate location and abuse prevention)
- App version, language, theme, and other in-app preferences
- Behavioral product analytics events about how you use the app - for example, when you create a profile, open your bodygraph, view a transit or connection chart, or change a setting
- Performance and crash data
Birth date, birth time, and birth location entered for chart calculation are stored locally on your device by default. They are only sent to our servers if you sign in (Section 2b), when a birthplace lookup cannot be resolved on your device (Section 2c), or when explicitly required to generate an AI-assisted reading (Section 2d).
b. App - Signed-In Use (Optional)
If you choose to sign in with Apple or Google to sync your profiles and readings across devices, we additionally collect and process:
- Your email address and display name (provided by Apple or Google)
- A unique account identifier (Firebase UID)
- Your saved profiles (name, birth date, birth time, birth location), reading history, chat history, notes, and app settings (synced to our cloud database so you can restore them on a new device)
- The date of your first sign-in
c. App - Birthplace Lookup
Birthplace search is resolved by your device's own geocoder where possible. If the device cannot resolve a place, the text you typed is sent to our Cloud Function to look up coordinates and time zone. We do not store the search text separately from your profile.
d. App - AI Features
When you request an AI-generated reading, interpretation, or answer in the Ask chat, the relevant chart context (such as your gates, channels, centers, Type, Authority, and Profile) and your question are sent to Anthropic and/or OpenAI for processing. The response is returned to your device and stored in your reading or chat history. We do not send AI prompt text to any analytics provider.
e. Website
The Gate 64 website (gate64.hexagramdreams.com) may use cookies and analytics to support functionality and understand traffic. These technologies may collect:
- Browser type and version
- IP address and approximate location
- Pages visited and time spent
- Cookies or similar identifiers
You can manage or disable cookies in your browser settings.
3. THIRD-PARTY SERVICES
We rely on trusted third-party providers to operate, analyze, and improve the Services. Each processes your data as our service provider and under their own privacy policies.
