Alto Connector — Privacy Policy

Last updated: July 26, 2026

Alto builds interactive timelines exclusively from materials you provide. This policy describes what the Alto connector and the Alto web app store and how it is used.

What we collect

• Account: when you sign in with Google we receive your Google account's basic profile (name, email, photo) and a stable user id. We never see your Google password.
• Timeline data: the project names, timeline structure, node text, and connections you author through the connector. Node content is text you supplied; Alto does not generate or store content beyond it.
• Study data: highlights, notes, and reports you create inside a timeline, synced to your account so they follow you across devices.

What we do NOT collect

• The source documents you share with Claude during an interview stay in your Claude conversation. The connector stores only a factual manifest (file names and kinds) you approve.
• No analytics, advertising identifiers, or tracking cookies. The only cookie is your signed session.

Storage & sharing

Data is stored in Google Cloud (Firestore and Cloud Storage) under your user id. Timelines are private: a published timeline opens only for the Google account that published it. Someone else can see one only through a share link you create, which exposes a copy of that one timeline page and which you can revoke at any time. We do not sell or share your data with third parties.

Retention & deletion

Data persists until you delete it. Deleting a timeline removes its drafts, builds, and sync data. To delete your account data entirely, contact us.
