SnapLine reads construction drawing sets so a tradesperson can ask questions about a job from a phone. This page says what SnapLine keeps, why, who can see it, and how to have it removed.

What SnapLine collects

Your Google account. When you sign in with Google, SnapLine receives your email address, name and profile picture. The email is how SnapLine knows who you are and which jobs are yours. The picture is shown as your avatar.
The files you add to a job. Drawing sets, specifications, addenda and contract documents that you upload, link, or pick from Google Drive. SnapLine stores the files, the text and images it reads out of them, and the sheets, schedules, legends and notes it finds.
Your questions and SnapLine's answers. Questions asked through the Claude connector, the tool calls they cause, the findings and notes you save, and corrections you make. SnapLine does not see your chat with Claude, only the requests the connector sends it.
Technical logs. Requests, errors and timing, kept to keep the service running.

Google Drive

The "Add from Google Drive" button asks Google only for the files you pick in the picker (the drive.file scope). SnapLine copies each picked file once and does not keep the Drive access token. It cannot see the rest of your Drive.

SnapLine's use of information received from Google APIs follows the Google API Services User Data Policy, including the Limited Use requirements.

How SnapLine uses it

To read your drawings and answer questions about them, with the sheet and location each answer came from.
To improve how SnapLine reads drawings. Missed or corrected answers are reviewed by the SnapLine admin and replayed against new code.
Never to sell, rent or advertise. SnapLine has no ads and shares nothing with data brokers.

Who can see your data

People on the job. A job's owner, anyone the owner shares it with, and SnapLine's admins.
Service providers that run SnapLine. Google Cloud hosts the service, stores the files and runs optical character recognition on pages; Anthropic's Claude reads page images and answers questions; Neon hosts the database. Each processes data only to provide its service.
The Claude app. Your conversation with Claude is held by Anthropic under Anthropic's own terms and privacy policy, not by SnapLine.

Cookies

SnapLine sets a sign-in cookie that lasts seven days, a cookie for your light or dark choice, and, for admins only, a short-lived cookie while viewing the app as someone else. There are no tracking or advertising cookies.

How long it is kept, and how to remove it

Files, findings and questions stay with the job while the job exists. Archiving a job hides it; it does not delete anything. To have a job, a file or your account deleted, email mathews.colton@gmail.com and it will be removed within 30 days. When an admin removes you, your access ends immediately and the account can't sign in again.

Security

All traffic is encrypted in transit. Sign-in is through Google; SnapLine never sees your password. Each person sees only their own jobs and the jobs shared with them, in the app and in Claude.

Changes

If this policy changes, the date at the top changes with it. Material changes will be announced on the app's home page.
