What Plus is not
Not a content paywall.Every case file, every finding and every source stays readable by anyone. Paywalling safety findings would be the wrong thing to do with this material.
Not ad removal.BlackBoxWiki has no ads and will not get them. There is no tracking and no third-party analytics, on any plan.
Not a research licence.Plus is a set of tools for reading and organizing. Reuse of the archive itself is governed by the Terms.
Billing
Payments are handled by Polar, our merchant of record. Checkout happens on Polar's own domain, so no payment or tracking cookies are ever set here.
Cancel any time from your Logbook. Access continues to the end of the period you have paid for. Saved cases, collections and notes are never deleted if you cancel — they become read-only above the free limits.
Prices include any applicable VAT or sales tax. See the Terms for refunds and the EU right of withdrawal.
