Frequently asked questions

All flow data comes directly from the Bitcoin blockchain — public, immutable, and verifiable by any full node. Provider attribution (which address belongs to which exchange / ETF / mining pool) is based on a tagging database maintained over years, currently with ~37 million provider tags.

Premium and Platinum users see new blocks instantly as they appear on the blockchain (roughly every 10 minutes). Free users see all data with a 60-minute delay.

A category groups similar entities — e.g. "Exchange" includes Binance, Coinbase, Kraken; "ETF" includes iShares, Fidelity, BlackRock products; "Mining" includes Foundry, AntPool, ViaBTC. There are about 15 categories from Exchange to Darknet.

Currently only Bitcoin (BTC). Extension to other UTXO-based coins (Litecoin, Bitcoin Cash) is conceptually possible, not currently planned.

Yes, Premium and Platinum users get live updates via WebSocket in the dashboard — no reload needed. Free users must refresh the page.

Free (€0): top-5 categories, 60 min delayed, 1 price alert. Premium (€19/month): real-time, all categories, live correlation, 5 alerts. Platinum (€39/month): adds provider-level flows, provider matrix, 20 alerts, and REST API access. Full comparison on the pricing page.

Yes, anytime. Upgrades take effect immediately; downgrades wait until the current subscription ends. Pro-rata upgrade credit is automatically applied.

Your account automatically reverts to Free — no cancellation or form needed. You keep access to your dashboard (with 60 min delay) and can upgrade again anytime.

The Free tier IS the trial — unlimited use. Lightning payments are irreversible, so no classical money-back guarantee. If you hit a real technical issue, let us know.

Exclusively via Bitcoin Lightning. You receive a BOLT11 invoice with QR code and scan it with any Lightning wallet — no credit card, no bank, no payment processor in between.

For beginners: Phoenix, Muun, Breez, Wallet of Satoshi. For pros: Zeus, Blixt, LND / Core Lightning with your own node. Any BOLT11-capable wallet works.

Invoices are valid for 15 minutes. If a payment fails (routing issues, insufficient capacity), your account stays unchanged — just generate a new invoice.

Yes, under Account → Subscriptions you'll find all paid invoices as PDF downloads.

No, Lightning only. On-chain fees and confirmation times would be impractical for monthly subscriptions.

Only the minimum: email (for login and alerts), password hash (argon2id), subscription status, alert configurations. No tracking, no ad IDs, no third-party analytics in the logged-in area.

Only technically necessary ones (session, CSRF token, theme preference). No advertising cookies, no third-party cookies. Details in the privacy policy.

Yes, under Account → Settings. The new address must be confirmed by email before it becomes active.

Under Account → Settings → "Delete account". All personal data is removed within 24 hours; anonymised subscription statistics remain for bookkeeping (legal retention requirements).

No. The only exception: for Lightning payments we use a self-hosted LNbits instance — payment metadata stays within our infrastructure.

All modern browsers from the last 2 years: Chrome, Firefox, Safari, Edge (desktop + mobile). No IE.

No native app. The web app is fully responsive and works well on mobile — "Add to Home Screen" in your browser gives a PWA-like experience.

The REST API is developer-oriented. If you can code (Python / JS), you'll get far quickly. Non-developers are better served by the dashboard CSV export.

Premium / Platinum: CSV export from dashboard tables. Platinum additionally: flow-observations export via API for bulk downloads.
