🔒 Privacy & Data

Your data never leaves your machine.

• All memory stored locally in ~/.clarik/
• No telemetry, no analytics server, no cloud sync
• No data transmitted except to Anthropic's API using your own API key
• You own your memory files — they're plain JSON you can read, edit, or delete
• License validation is the only network call (Gumroad, once per 24 hours)

❓ FAQ

Does Clarik send my code anywhere?

No. Everything stays on your machine. Clarik stores memories as local JSON files. The only network request is license validation via Gumroad (Pro users, once/day).

Does it work with Claude Desktop and Claude Code?

Yes. The installer detects and configures both automatically.

What happens when my context fills up?

Clarik can save a checkpoint of your current session — goal, progress, decisions, next steps. Start a fresh session and resume instantly with clarik_checkpoint_resume.

Can I use it offline?

Yes. Free tools work offline always. Pro tools have a 5-day offline grace period after your last successful license check.

Does it work on Windows?

Yes. Full Windows support with automatic cmd /c wrapper for stdio compatibility. Also works on macOS and Linux.

Will it conflict with other MCP servers?

No. All tools are prefixed with clarik_ to prevent naming conflicts.

Can I see what Clarik has memorized?

Yes. Use clarik_memory_list to see all stored memories, or browse the JSON files directly in ~/.clarik/projects/.

How do I delete my data?

npx clarik uninstall        # Remove from Claude configsrm -rf ~/.clarik/           # Delete all stored data

🔧 Compatibility

Known Issues

• macOS beta: MCP connections may be unstable on macOS beta releases. The installer will warn you if a beta version is detected.
• Transport: Clarik uses stdio transport only. SSE and HTTP transports are not supported due to known MCP compatibility issues.

🔍 Troubleshooting

Clarik tools don't appear in Claude

1. Make sure the install completed successfully: npx clarik status
2. Restart Claude Desktop / Claude Code
3. Check that the MCP config file was written correctly:
   • Mac: ~/Library/Application Support/Claude/claude_desktop_config.json
   • Windows: %APPDATA%/Claude/claude_desktop_config.json
   • Linux: ~/.config/Claude/claude_desktop_config.json

"Connection lost" or frequent disconnects

Clarik includes a 30-second heartbeat ping to keep the connection alive. If you still experience disconnects:

1. Update Claude Desktop to the latest version
2. Avoid macOS beta releases if possible
3. Check ~/.clarik/ directory permissions

License activation fails

1. Check your internet connection
2. Verify the key format: CLARIK-XXXX-XXXX-XXXX
3. Try again — Gumroad's API occasionally has brief outages
4. Pro tools work offline for 5 days after last successful check

📊 How Memory Works

What Clarik Learns

• ✅ Stack and framework choices ("We're using Next.js 14 with App Router")
• ✅ Architectural decisions ("Moved from REST to tRPC")
• ✅ File purposes ("lib/auth.ts handles JWT and sessions")
• ✅ Gotchas and warnings ("Don't use the v2 API — it's broken")
• ✅ User-confirmed facts

What Clarik Never Learns

• ❌ Thinking blocks (<thinking>, <antml-thinking>)
• ❌ Chain-of-thought traces
• ❌ Speculative guesses
• ❌ Content before a user correction

Memory Ranking

When recalling memories, Clarik scores each fact:

score = (relevance × 0.5) + (recency × 0.3) + (importance × 0.2)

Only the highest-scoring facts are injected into context — never everything at once.

Project Isolation

Each project gets its own memory space, derived from:

git remote URL → workspace root → package.json name

React project memories never appear in your Python project.
