Account & Data Deletion

GDPR Article 17 (Right to Erasure) • Google / Apple Platform Compliance

Commitment to Data Privacy GDPR Art. 17

At COT Bias Terminal (operated by Stochastic Systems UG (haftungsbeschränkt) i.G.), you have complete control over your personal data. In accordance with Article 17 of the General Data Protection Regulation (EU GDPR) and third-party platform policies (Google OAuth, Apple App Store, Google Play), you can request immediate and permanent erasure of your account and all associated personal information at any time.

Users can delete their data using either the In-App Self-Service tool or via a Public Manual Erasure Request without needing to log in.

Method 1: In-App Self-Service Deletion Instant

If you can log in to your account, you can permanently erase your record in seconds directly inside the terminal:

  1. Sign in to your account at COT Bias Terminal App.
  2. Click on your profile avatar or gear icon in the top right corner to open User Settings.
  3. Scroll down to the Privacy & Security / Danger Zone section.
  4. Click "Delete Account & Data".
  5. Confirm your action in the verification modal. Once confirmed, your Firebase Authentication identity, session tokens, and personal records are permanently erased immediately.

Method 2: Public Manual Deletion Request No Login Required

If you no longer have access to your account, authenticated via a third-party provider (Google Sign-In), or wish to initiate deletion from outside the terminal, send an email to our Data Protection Officer:

Email: privacy@stochastic-systems.com
