Privacy Policy

At AMS Solutions d.o.o. (hereinafter "we" or "controller"), we respect your privacy. The Tremble application is built on the principle of "Privacy by Design", meaning we only collect data strictly necessary for the operation of the real-time radar experience.

1. Data Controller

AMS Solutions d.o.o., Slovenia
Contact for privacy inquiries: privacy@tremble.app

2. Data Collected and Purpose

2.1 Location Data and Ephemerality

• Ephemerality: We do not store your location data history; after 10 minutes of inactivity, all traces of your location are deleted. We do not create maps of your movement nor store historical coordinates on our servers.
• Background Location: To receive proximity notifications of other users when the app is closed, we require background location access. This data is used exclusively for immediate proximity calculation.

2.2 Profile Data

Upon registration, we collect:

• Identifiers: Name (nickname), email address, Firebase UID.
• Profile Content: Photos, age, gender, and personal traits (preferences, hobbies). This data is stored until your account is deleted.

3. Security and Mutual Detection Mechanism

User safety in the physical world is our priority. To prevent abuse and unwanted tracking, we developed the Mutual Detection system:

• Mutual Detection: Your profile only appears on another person's radar if your device detects their signal and their device simultaneously detects yours.
• Anti-Stalking Safeguard: The radar does not display your exact coordinates, only direction and relative distance. No one can "see" you on the radar remotely without being in your immediate physical vicinity and without the system confirming mutual presence.
• Interaction Control: User identity is fully revealed only after mutual confirmation of interest ("Wave").

4. Legal Basis for Processing

• Performance of a Contract: For creating a profile and basic app operation.
• Consent: For access to GPS location and Bluetooth sensors. You may withdraw consent at any time in your phone settings.
• Legitimate Interest: For preventing abuse (blocking violators) and ensuring system technical stability.

5. Data Retention and Deletion

• Active Profile: Data is retained as long as you use the application.
• Account Deletion: You may select "Delete Account" in your profile settings at any time. This action irreversibly deletes your profile, email, and all photos from our databases (including Cloudflare R2 storage).
• Right to be Forgotten: We process all deletion requests as quickly as possible, in accordance with the GDPR.

6. Data Recipients

We do not sell your data to third parties. For technical operation, we use verified processors within the EU:

• Firebase (Google Cloud): For secure database storage and authentication.
• Cloudflare: For fast and secure loading of your profile images.
• Mapbox: For visualising the radar interface.

7. Your Rights

In accordance with the GDPR and ZVOP-2, you have the right to access, rectify, delete, restrict processing, and the portability of your data. To exercise these rights, email us at privacy@tremble.app. We will respond to your request within 30 days.

You also have the right to lodge a complaint with the supervisory authority — the Information Commissioner of the Republic of Slovenia (www.ip-rs.si), if you believe the processing of your data is not in accordance with applicable legislation.
