Privacy

Verdania runs on synthetic data and virtual capital, so it needs very little about you. You can explore every page without an account.

Browsing without an account

No account, no profile and no tracking. The site sets no analytics or advertising cookies.
If you switch language, a cookie remembers your choice for a year.
To stop abuse, the website counts each IP address's requests for a few minutes, in memory. The counts are never stored.

Supabase, which runs our sign-in, keeps what Google shares: your name, email address and picture link, and when you last signed in. Your email is never shown on the site.
Your profile holds only a display name and picture link, and it is private.
Signing in adds two cookies: one keeps you signed in, and the other remembers for up to ten minutes which page to return you to after you sign in.
Signing in grants no special permissions. Moderator and researcher roles are given separately.

Saved scenarios are private. If you publish one, the Community page shows its title, notes, assumptions and results, but not your name.
Moderators can hide a published scenario from the Community page. Each such action is recorded with who did it and why.

Your portfolio and its history of virtual units are private.
Public totals add up everyone's choices, and stay hidden until a project has at least five participants.

We keep your message, and your name and email if you give them, only to read it and reply. Only the project team, including moderators, reads them.

Supabase holds the database and sign-in. Amazon Web Services in Sydney, Australia, runs the website and the simulation engine. Google handles the sign-in itself.
These providers keep standard technical logs, such as IP addresses, for a short time to run and secure the service.
We do not sell your data, show advertising, or share your data with anyone else.

Unpublish or delete any scenario, and withdraw virtual units, at any time.
Delete your account from your account page. That removes your sign-in record, profile, roles, every scenario (published ones too) and your virtual portfolio. Suggestions you sent stay, without your name and email. The audit log keeps only your former account ID, which no longer links to anything.
To have a suggestion deleted, or for any other question about your data, send us a message. Send a message
