Sessions and token

On opening, “Start” gives you an 8-character token, shown in the “Your unique token” frame of the banner; “Copy” puts it in the clipboard. There is no account and no password: the token is your only key.

It opens all your sessions, on this device or another, and it encrypts your data: without it, nobody can read them, neither the site operator nor the host (Data protection). Keep it somewhere safe: a lost token cannot be recovered.

The token can be typed with or without the hyphen, in upper or lower case; a digit typed for the letter it looks like (5 for S, 2 for Z, 8 for B, 6 for G) is read as that letter.

The same token opens up to 10 sessions: as many scenarios of the same undertaking, for example without and with reinsurance, before and after a change of asset allocation, the closing and the plan. Each session has its name, its settings and its inputs, and is calculated separately.

The “Session n — name” button of the open session, next to the token, lists them and allows you:

• to open another session;
• to create an empty session, or a copy of the open session (settings and inputs, never the results): the fastest way to vary a scenario;
• to rename the open session.

The comparison is made from one session to the other: each one is calculated, then the results are compared.

Each answer of the settings and each data item entered is saved, encrypted, as soon as the field is left: there is nothing to save. Closing the page or the browser loses nothing.

Results, however, are never kept from one visit to the next. A session that is reopened, resumed on another device or reloaded from a file is shown without results: “Run the calculation” recalculates it with the formulas and parameter tables in force. Between two visits, the reference data may have changed (monthly symmetric adjustment, amended text): an old result might no longer be right.

If the reference data require one more data item, the calculation stops and points to it.

The browser finds your session on its own thanks to a technical cookie. On another device, or after deleting cookies, “Resume a session” asks for the token: all the sessions of the token come back, the first one opens.

A token is active on only one browser at a time: resuming it elsewhere disconnects the previous device, which reports it at its next action and asks for the token again.

To slow down random attempts, the same address cannot try more than 10 resumptions in 15 minutes.

“↓ Download this session” saves on your device a file of the open session: its number, its name, its settings and its inputs, encrypted as in the database, never the results. The file can only be read with the token.

“↑ Upload one of your sessions” reloads such a file with the token: the session with the same number takes the content of the file, whether it still exists or has been erased; the other sessions are not affected. It is shown without results and is recalculated.

The file serves as an archive: it keeps a session beyond the erasure period, or freezes it at a date, for example the closing presented to the board.

“Delete this session” erases, as chosen, its calculations, its inputs or the whole session; the other sessions of the token are not affected. Deleting the last session erases the token.

Without use for 30 days, the sessions of a token are erased by a daily task of the server; using a single session of the token keeps them all alive. A downloaded file recreates an erased session.
