Additional information

No analytics or advertising services are used. Price data is retrieved server-side from the Binance Market Data API and from Yahoo Finance – no data about you is transmitted to these providers. Computed signals are cached for a few minutes per asset only, without any personal reference.

User account (Supabase Auth): To sign you in, we store your email address, sign-in times and – when signing in with Google – your name and Google identifier. The login session is kept in your browser’s local storage; this is technically required for the login you requested (§ 25 (2) no. 2 TDDDG). Legal basis: Art. 6 (1) (b) GDPR. Provider: Supabase, Inc.; database hosted in Frankfurt (EU).
Login emails (Resend): We send login codes and cancellation confirmations via Resend, Inc. (USA). This involves processing your email address and the message content.
Sign in with Google: Google Identity Services (Google Ireland Ltd.) is only loaded – and your IP address only transmitted to Google – when you click “Continue with Google” in the login dialog.
Payments (Stripe): For Pro subscriptions you are redirected to Stripe Payments Europe, Ltd. We do not receive your payment details; we only store the subscription status, Stripe customer and subscription IDs, your email address and proof of your consent to the Terms and to the early start of the service (statutory retention obligations under German commercial and tax law).
Usage: For the free quota we record which analysis (asset, timeframe, time) you requested.
Hosting (Netlify): The website is delivered by Netlify, Inc.; server log data (e.g. IP address, time of access) is processed for this purpose.

You can delete your account at any time in the account area. You can exercise your rights (access, rectification, erasure, restriction, data portability, objection and the right to lodge a complaint with a supervisory authority) by email to the address above.
