Monero GUI vs Proton Wallet Comparison

Monero's own 25-word seed: 24 words encode the private spend key and the 25th is a checksum. It is not BIP39, but it is the most widely used seed format among Monero wallets. The GUI creates and restores only this format, and can also restore a wallet from its private keys or from a hardware wallet.

Each wallet has its own BIP39 phrase of 12 words. The phrase is not shown when the wallet is created; it is encrypted on your device and stored on Proton's servers, and you can display it later in the wallet's settings after entering your account password.

The Monero Project calls itself a loose collective of individuals; the GUI has no company behind it. The terms of use of getmonero.org, last revised in June 2017, are governed by the laws of South Africa.

The terms name Proton Financial AG, a Swiss company that is a wholly owned subsidiary of Proton AG, as the operator; the privacy policy gives its address in Baar, canton Zug. Proton says it discloses the limited user data it holds only on a binding request from competent Swiss authorities. Disputes with consumers outside the US go to the courts of the canton of Zug; US consumers face arbitration.

Built by volunteer and crowdfunded contributors under the oversight of the Monero Core Team. No part of the block reward goes to development; the project is funded by donations to its General Fund and through the Community Crowdfunding System.

Proton Financial AG belongs to Proton AG, whose primary shareholder is the non-profit Proton Foundation; Proton says no change of control can happen without the Foundation's consent.
