Google API Services Disclosure

Last updated: April 16, 2026

Limited Use affirmation

RoughSketch's use and transfer of information received from Google APIs to any other app will adhere to the Google API Services User Data Policy, including the Limited Use requirements.

What Google APIs we use

RoughSketch integrates with Google to let you sign in with your Google account and save diagrams to your own Google Drive. We request the following OAuth scopes:

  • openid, email, profile — to sign you in and display your name and avatar.
  • https://www.googleapis.com/auth/drive.file — the narrowest Drive scope Google offers. It grants RoughSketch access only to files you open or create with RoughSketch. We cannot see or modify any other file in your Drive.

How we handle Google user data

  • Diagram content is transferred directly between your browser and Google Drive. RoughSketch's servers are not on that data path and do not store the contents of your diagrams.
  • The only Google user data persisted on our infrastructure is an OAuth refresh token, encrypted with AES-256-GCM and stored in Cloudflare Workers KV, used solely to keep you signed in.
  • No humans read your Google user data except as necessary for security investigations, to comply with the law, or where you affirmatively consent.
  • We do not use Google user data to develop, improve, or train generalized artificial-intelligence or machine-learning models.
  • We do not sell Google user data, use it for advertising, or transfer it to third parties for advertising or data-broker purposes.

How to revoke access

You can revoke RoughSketch's access to your Google account at any time at myaccount.google.com/permissions. Revocation takes effect immediately and invalidates the encrypted refresh token we hold. You can also sign out from within the app, which deletes the refresh token from our infrastructure and clears your session cookie.
