Privacy Policy

Hmmmm is a thinking tool. Your thoughts are personal. We treat them that way.

What we collect

When you create an account, we store your email address. When you use the app, we store the thoughts, sessions, chains, and links you create.

How we use your data

Your data is used only to provide the service to you. We do not sell, share, or use your data for advertising. We do not use your data to train AI models.

Where your data is stored

Your data is stored on a server hosted by Fly.io in their European data centre. Data is encrypted in transit (HTTPS).

Cookies

We use a single session cookie to keep you logged in. We do not use tracking cookies or analytics.

Shared chains

If you share a chain of thought, anyone with the link can see that chain. Only the chain you explicitly share is visible. You can revoke access at any time by regenerating the shared link, which immediately invalidates the old link.

Shared sessions

If you share a session, anyone with the link can see the session graph and read the chains within it. Only the session you explicitly share is visible. Your account information is not shown on shared pages. You can revoke access at any time by regenerating the shared link from the session page.

Account deletion

You can delete your account at any time from the Account page. This permanently removes your email, all your sessions, thoughts, chains, and links.
