LineBreak

Privacy Policy

Effective date: May 13, 2026  ·  Baktun Studio LLC  ·  Last updated: May 13, 2026

LineBreak is a local-first product. The agent runs on your machine. Your code, prompts, and project history never touch a LineBreak server. This policy explains the limited data we do collect, and what we don’t.

1. Who we are

LineBreak is a product of Baktun Studio LLC (“Baktun Studio,” “we,” “us,” or “our”), a limited liability company. Our product is accessible at linebreakapp.com and linebreak.dev. You can reach us at support@linebreakapp.com.

2. What data we collect

We collect the minimum data necessary to operate the product. We do not sell your data. We do not run advertising.

Account information. When you sign in with GitHub or Google OAuth, we receive your email address, display name, and profile avatar URL from the provider. We store this to identify your account and issue you an access token.

Usage telemetry (opt-in). During first launch, you are presented with a consent screen that includes an opt-in checkbox for product analytics. If you opt in, we collect anonymized events such as:

  • App lifecycle events (launch, session start, crash)
  • Feature usage events (project created, gate approved, phase completed)
  • Error events (backend unreachable, authentication failure)

These events are sent to PostHog (analytics) and Sentry (crash reporting). They never include your code, your prompts, or project content. If you opt out, no telemetry is sent. You can change this preference at any time in Settings → General.

Website analytics (consent-based). On this marketing website (linebreakapp.com) we use Google Analytics 4 to measure aggregate traffic and which pages and actions (for example, starting a download or viewing pricing) are popular. These cookies load only after you accept them in the cookie banner shown on your first visit; if you decline, no Google Analytics cookies are set and no analytics data is sent. You can withdraw or change this choice at any time using the “Cookie preferences” link in the site footer, which also clears any Google Analytics cookies. This is separate from the in-app telemetry above and never involves your code, prompts, or projects.

LLM provider traffic. When the agent runs, it sends prompts to your chosen LLM provider (Anthropic, OpenAI, Azure OpenAI, or a local model). This traffic goes directly from your machine to the provider; it does not pass through LineBreak servers. The provider’s own privacy policy governs that data. If you use your own Azure OpenAI tenant or a local model, no data leaves your network at all.

Metering events. We collect structured usage events (action type, phase, timestamp, installation ID) to support future billing and quota enforcement. These events do not include code or prompt content. They are stored in our Cloudflare D1 database.

License service interactions. Our licensing service (hosted on Cloudflare Workers) receives your user ID and installation ID when the app checks your entitlements. We log standard Cloudflare access logs (IP address, timestamp, HTTP method and path) subject to Cloudflare’s data retention policies.

3. What we do not collect

  • Your source code, in whole or in part
  • Your prompts or agent conversations
  • Your project artifacts (PRDs, architecture documents, approval records)
  • Your git history or repository contents
  • Your LLM API keys (stored only in your local OS keyring)
  • Your Azure DevOps, GitHub, or Jira credentials (stored only in your local OS keyring)

4. How we use your data

  • Account management: to authenticate you, maintain your session, and issue entitlement policies.
  • Product improvement: to understand how features are used and where the product fails (crash reports, error events).
  • Billing and quotas: to enforce plan limits and, when paid tiers launch, to bill accurately.
  • Communications: to send transactional emails (waitlist confirmation, billing receipts). We do not send marketing email without explicit consent.

5. Data storage and retention

Account data and metering events are stored in Cloudflare D1 (a SQLite-based database hosted on Cloudflare’s global network). Cloudflare stores data in the United States and European Union depending on your region.

Telemetry data is stored in PostHog Cloud (US region) and Sentry (US region).

We retain account data for the lifetime of your account. Metering events are retained for 12 months on Free tier. Paid tiers have longer retention periods as described in your plan.

You can request deletion of your account and associated data at any time by emailing support@linebreakapp.com. We will process deletion requests within 30 days.

6. Data sharing and sub-processors

We share data only with the following sub-processors, to the extent necessary to operate the product:

  • Cloudflare, Inc.: hosting, DNS, D1 database, Workers runtime
  • PostHog, Inc.: product analytics (opt-in only)
  • Sentry (Functional Software, Inc.): crash reporting (opt-in only)
  • GitHub, Inc.: OAuth authentication (if you use GitHub sign-in)
  • Google LLC: OAuth authentication (if you use Google sign-in)
  • Google LLC (Google Analytics): website traffic analytics on linebreakapp.com (cookies, only after you accept)
  • Stripe, Inc.: payment processing (when paid tiers launch)

We do not sell, rent, or share your personal data with any other third party for their own purposes.

7. Your rights

Depending on your jurisdiction, you may have the following rights regarding your personal data:

  • Access: request a copy of the personal data we hold about you.
  • Correction: request that we correct inaccurate data.
  • Deletion: request that we delete your account and associated data.
  • Portability: request your data in a machine-readable format.
  • Objection: object to processing based on legitimate interests.
  • Opt-out of telemetry: change your telemetry preference in Settings → General at any time.

To exercise any of these rights, contact us at support@linebreakapp.com. We will respond within 30 days.

8. Children’s privacy

LineBreak is not directed at children under 13. We do not knowingly collect personal data from children under 13. If you believe we have inadvertently collected such data, please contact us and we will delete it promptly.

9. Security

We implement industry-standard security practices including HTTPS for all data in transit, HMAC-signed entitlement documents, short-lived access tokens (1-hour TTL), rotating refresh tokens (90-day TTL), and OS keyring storage for all credentials on the desktop client. No system is perfectly secure; we encourage you to use strong passwords and keep your OS and LineBreak up to date.

10. Changes to this policy

We may update this policy as the product evolves. When we make material changes, we will update the effective date at the top of this page and, where appropriate, notify you via the in-app update banner or email. Continued use of LineBreak after the effective date constitutes acceptance of the updated policy.
