Privacy Policy
Last updated September 2026
Stackt is a private household investment tracker. It is used only by the people its admin explicitly invites, and it is not open for public sign-up.
What we collect
When you sign in with Google, we receive your name, email address, and profile picture -- nothing else from your Google account. Any financial information (account balances, contributions, goals) is information you or another invited household member enters directly into the app.
How we use it
Your Google identity is used only to sign you in and to know which household you belong to. Financial data you enter is used only to show you the dashboards, charts, and projections inside the app.
Who can see your data
Only the members of your own household can see your household's data. This is enforced by the database itself (Row Level Security), not just by the app's screens -- another household's members can never see yours, and vice versa.
Third parties
We do not sell, share, or advertise using your data. Your data is stored with Supabase (our database provider) and Google is used only to confirm your identity at sign-in.
Removing your data
If you'd like your account and data removed, contact the household admin who invited you, or whoever manages this app for your household.
