Privacy policy

Last updated: 2026-04-28

The short version

Stonekept is a personal memory system. Recordings, transcripts, and extracted memories live on your device. When you turn on Sync, those memories travel between your devices as encrypted blobs sealed with a key only your devices hold. Stonekept's servers cannot decrypt them.

What we collect

• Free tier: nothing on our servers. Free users do not have a Stonekept account.
• Sync tier: an account email, a device list, and encrypted memory blobs. Server-side data is opaque to us.
• Pro tier (AI access): the above, plus connection metadata for any MCP clients you authorize. Query contents are never stored, never logged, and never analyzed. The broker holds them in memory only for the seconds of an in-flight request, then forgets them.
• Waitlist: email and platform you indicated. Used once, to notify you when that platform ships.

What Stonekept the broker can read

Claude Desktop on Mac uses a fully local stdio bridge that never reaches our servers. Your queries and your memories stay on your machine. There is no broker in this path and no network traffic leaves your laptop for AI access.

claude.ai web and the Claude mobile app route through the Stonekept broker. Those queries transit our servers. Our policy is no storage and no analysis, and we can see envelope metadata (who is talking to whom, how often). For maximum privacy on AI access, use Claude Desktop on a Mac. Anthropic still sees what Claude sees on either path, since that's the connection you authorized.

What we never do

• We do not sell or rent your data to anyone.
• We do not train models on your memories.
• We do not log AI query contents on our servers.

Your rights

You can export, delete, or end Sync at any time from the app. For data subject requests under GDPR or CCPA, email privacy@stonekept.com.
