Walkmark

Privacy and data

Walkmark is built to keep capture and storage on your machine by default.

Always local

These never require the network:

Activity Stored where
Screen and window recording projects/<id>/frames/*.png
Project metadata and edits projects/<id>/project.json
Reorder, merge, exclude, annotations Same project folder
Export to Markdown / HTML / PDF Path you choose at save time
App preferences settings.json in app data
API keys (BYOK) credentials.<provider> + OS secret store

Projects live in your platform app data directory as plain folders. Walkmark does not operate a sync service for open source users.

App data locations

OS Path
macOS ~/Library/Application Support/app.walkmark.desktop/
Windows %APPDATA%\app.walkmark.desktop\
Linux ~/.local/share/app.walkmark.desktop/

You can back up, encrypt, or sync this folder with tools you trust. Walkmark does not encrypt project folders separately from your disk encryption.

When data leaves your machine

Data is sent only when you run Write with a model that is not purely local:

Setup Where screenshots and prompts go
Ollama / compatible server on localhost Your machine only
Compatible server on LAN Your network
Bring your own key (Gemini, OpenAI, Anthropic, Mistral, OpenRouter) That provider's API
Walkmark Cloud (coming soon) Walkmark-hosted models under Cloud terms

Walkmark does not upload frames in the background. If you never click Write, or you only use local models, cloud providers never receive your screenshots.

What is sent on Write

For each write job, the configured provider receives:

  • Step screenshots (vision models)
  • Prompt text (audience, tone, language, vocabulary, step context)
  • No unrelated projects or library metadata

Outline pass sends all included frames; step pass sends one frame per step plus prior step text.

API keys

Keys you enter for BYOK providers are:

  • Verified once against the provider API
  • Stored locally in app data and mirrored to the OS keychain / Secret Service when available
  • Read only by the Walkmark process to sign requests

Walkmark never receives or stores your keys on our servers.

Delete keys by removing them in Settings or deleting credentials.<provider> while the app is quit.

Walkmark Cloud

The paid Cloud plan (separate from this open source app) will include its own privacy terms when it launches. The OSS app remains fully usable without an account.

Telemetry

The open source app does not include analytics or crash reporting today. If that changes, it will be opt-in and documented here.

Enterprise

Teams with SSO, audit logs, or on-prem deployment requirements can contact us.
