Page and data requests

This website is hosted on Cloudflare Workers. Cloudflare processes connection information needed to return pages, serve website assets and protect the service, including IP addresses and request metadata. Operational logs are sampled; we do not deliberately log wallet request bodies or server credentials.

The XRP wallet check sends the public address you enter to our server and fixed public XRP Ledger nodes to read its ledger records. A public address can be linked with transaction history. No keys, seed phrases or signing permissions are requested. Cloudflare Durable Objects enforce request limits using a keyed hash of the connecting IP address. The limiter stores request counts and expiry times, without raw IP addresses or wallet addresses; expired entries are automatically deleted. Cloudflare KV caches public source data.

Optional storage on your device

The light/dark preference is stored locally in your browser. Watchlist, portfolio and wallet options store entries only when their controls offer that choice. Use the relevant remove or forget control, or clear this site’s browser storage, to remove saved entries.

Calculator entries are processed in the browser. Downloaded CSV files remain on your device; a CSV download is not a submission to an exchange or the IRS.

External data and links

Market and research data are requested by our server from named public sources. The English site does not connect to the German magazine database, newsletter list or YouTube membership accounts.

Following an external manufacturer, exchange, YouTube or Fourthwall link takes you to that provider’s service, where its privacy policy applies. Fonts are served as website assets rather than requesting fonts from Google when you read a page.

Tracking and marketing

This implementation does not load analytics, advertising pixels or third-party video embeds. It does not reuse the German site’s measurement identifiers. New marketing or account services require their own configuration and an updated notice.

Privacy requests

Contact the operator to ask about personal information processed by this site, seek correction or deletion, or exercise applicable privacy rights. Include enough information to identify the request without sending wallet secrets. You may also contact the relevant data protection authority.
