Privacy Policy
Last updated 24 October 2026
WickCheck ("we"), owned and operated by Mindaugas Knašas, runs wickcheck.com, a trading backtesting tool. This policy explains what we collect and why.
What we collect
When you create an account: your name, email address and, if you sign in with Google, your basic Google profile (name, email, profile picture). We also store the backtests, strategies and preferences you save, and when you last signed in.
Free test limit
Visitors without an account can run 3 free backtests. To enforce this we count tests per IP address and per device fingerprint (a hash of basic browser and screen settings). Both are stored only as one-way keyed hashes, never in readable form, and the count resets after 30 days.
How we use it
Only to run your account: signing you in, saving and showing your work, and contacting you about your account. We do not sell your data and do not use it for advertising.
Google sign-in
We request only the basic profile and email scopes. Google user data is used solely to create and sign in to your WickCheck account and is not shared with third parties.
Email alerts
If you turn on an email alert, we store the alert (market, timeframe and rules) and email you when it signals. You can pause or remove alerts at any time. Emails are sent through Brevo (Sendinblue SAS, France), which processes your email address only to deliver them.
AI strategy reading
To understand strategies written in your own words, the text you type into the tester is sent to Anthropic's Claude API (Anthropic PBC, USA), which turns it into rules our engine can test. Only the strategy text is sent, not your name or email. We keep the result in a cache so the same text doesn't need to be sent again. Don't put personal information in your strategy text.
Payments
Payments are processed by Stripe, which acts as the seller of record. We never see or store your card details; we only keep your Stripe customer and subscription IDs so we can switch your plan on and off.
Where it is stored
On our own server hosted by Hetzner in the EU. Data is sent over HTTPS.
Your rights
You can ask us to export or delete your account and data at any time by emailing us; we do it within 30 days.
Visit statistics
We count page views without cookies. For each visit we store the page, the referring website (domain only), the language and whether it was a phone or a computer. The visitor id is a one-way hash of your IP address and browser that changes every day, so visits cannot be linked across days, and the IP address itself is never stored.
Weekly email
If you subscribe, we store your email address, language and the page you signed up on. Nothing is sent until you click the confirmation link. Every email has a one-click unsubscribe link, which deletes your address.
Cookies
We use your browser's local storage to keep you signed in, remember your language and count free tests. No tracking cookies.
