Edit profile opens your first name, last name and email: change the names and click Save, and they are saved at once, also in how the projects name you. To change the email, type the new one and click Save: SyncNow sends a code to the new address, and the email changes only when you type that code in the same window and click Confirm email; until you type it, you keep signing in with the old email. Afterwards you sign in with the new one, the old address receives a notice, and your other PCs stay signed in. An address already used by another account cannot be chosen.
Other sessions appears only when your account is signed in and active on other PCs right now, and names them; next to it, Manage sessions lists them with their SyncNow version and when they were last seen: Revoke signs that PC out, and it asks to sign in again at its next contact with SyncNow. This PC cannot be revoked there: use Logout. Updates are not here: they have their own item in the sidebar.
Language chooses Italiano or English as the language of your content: SyncNow writes its suggestions for you in it and asks your agents to write their plans, questions and answers in it, while the app itself stays in English. The choice is saved at once on SyncNow's server, for every PC where you sign in, and if it cannot be saved the previous language comes back and the section says why; see Which language is SyncNow in, and what does Language in Account change?. Session has Logout, which signs you out on this PC only, after a confirmation, and ends the sessions its agents opened from it. Delete account has the red Permanently delete account button, which opens a confirmation window: it explains what is lost and what is kept, Email me a code sends a one-time code to your account email, and the red button works only once you type that code and your account email. It cannot be undone, and nothing is deleted if the code or the email is wrong.
