Security at Stacks

Stacks uses authenticated access controls for private data, transport encryption, and time-limited links for private product media. Public and link-only Stacks are intentionally viewable by others according to their sharing settings.

Keep your sign-in email secure. Treat link-only Stack URLs as private invitations; anyone with the link may be able to view the Stack until it is changed or removed.

To report a security concern, email trystacks@gmail.com with enough detail for us to investigate. Please do not include passwords or sensitive personal data in your first message.
