Who processes data for us
- Ghost (Ghost Foundation) - hosts the website, member accounts and sends our emails.
- Stripe - processes payments. Stripe receives your payment details directly; we never see your card number.
These providers may process data outside the EU (for example in the United States). Such transfers are covered by the EU Standard Contractual Clauses or other safeguards required by the GDPR.
Cookies and similar technology
- Necessary cookies from Ghost keep you signed in. Stripe uses necessary cookies during checkout to prevent fraud.
- Embedded charts are loaded from TradingView, which may set its own cookies; see TradingView's privacy policy. Some pages load a chart library from cdnjs (Cloudflare).
- Watchlist: the companies you add to your watchlist are stored only in your own browser (local storage) and are never sent to us.
How long we keep data
Account data as long as you have an account; when you delete it, we delete your data within 30 days, except billing records we must keep by law (in the Czech Republic usually up to 10 years).
Your rights
You can ask for access to your data, correction, deletion, restriction, a copy in a portable format, and you can object to processing based on legitimate interest. Most of this you can do yourself in your account (including deleting it and unsubscribing). Otherwise contact us at whalewatchreports@gmail.com. You can also complain to a data protection authority - in the Czech Republic the Office for Personal Data Protection (uoou.gov.cz).
Changes
We will update this page if we change how we use data and tell members about important changes by email.
