The rule behind every tool here
No tool of ours will ever ask for your seed words.
Not to check them, not to recover them, not to “verify” anything. Every calculation above runs in your browser, nothing is uploaded, and none of them need an email address to give you the answer. If a site in this industry asks you to type twelve words into a box, close the tab.
- Answers first, email optional — and only for the written version
- No analytics on your answers. They stay in your browser or nowhere
- When a tool says the answer is “no”, that is the real answer
