Google and Chrome disclosure

Effective date: 29 August 2026. This page is the public counterpart to Chrome Web Store Limited Use and Google API language used by Gmail extensions. SentCue v1 does not use Google APIs.

What we do not do

• No Gmail API, Gmail add-on, or Google OAuth consent screen.
• No read/send/delete of your mailbox through Google.
• No Google Drive, Contacts, or Calendar scopes.
• We do not use Google user data to develop, improve, or train generalized AI or ML models.

Products such as Streak or Mailtrack that connect a Google account publish a different disclosure because they request those APIs. Copying their OAuth text would be false for SentCue.

What the Chrome extension does

• storage — settings, disclosure acknowledgement, local To/subject/fingerprint/thread bind, install secret.
• Host access to https://mail.google.com/* — content scripts on Gmail web (compose, Undo snackbar, Sent row UI).
• Host access to https://pixel.sentcue.com/* (and historically t.sentcue.com) — register/arm/cancel/status/config and the tracking image. Review builds do not include localhost.

Message body, attachments, passwords, and Gmail cookies are not sent to the SentCue backend. To, subject, fingerprint, and thread id stay in Chrome storage on your device in v1.

Limited Use

User data handled by the extension is used only to provide or improve the disclosed single purpose: show the Gmail-web sender a technical activity signal for messages they choose to track; plus security, operations, or legal requirement. We do not sell it or use it for advertising.
