Privacy Policy

Your roasts are yours. This explains what we collect, what we don't, and the controls you have.

Last updated: May 30, 2026

Overview

Roastline ("we", "us") builds an AI copilot for coffee roasting. We designed the product to keep your roasting data under your control — including the option to run the AI entirely on your own hardware. This policy describes how we handle personal and roast data when you use our website, desktop agent, and cloud services.

Local-first by design. In local mode, your telemetry and AI inference stay on your roastery floor and are never transmitted to us.

What we collect

We aim to collect the minimum needed to run the service:

  • Account data — name, email, roastery/company, and authentication credentials.
  • Billing data — handled by our payment processor; we store only a token and plan details, never full card numbers.
  • Product usage — feature usage and diagnostics to improve the app.
  • Support communications — messages you send us.

Your roast data

Roast telemetry (BT, ET, RoR), profiles, and cupping scores are yours. When you use cloud sync or cloud AI, this data is processed to deliver guidance, predictions, and reports. We do not sell it, and we do not use an individual roastery's data to train models for other customers without explicit, opt-in consent.

How we use data

  1. To provide live guidance, cup prediction, autopilot, and reports.
  2. To sync your roast history across your devices (when enabled).
  3. To improve reliability and product quality through aggregated diagnostics.
  4. To communicate about your account, security, and service updates.

Local & offline mode

If you run Roastline with a local model, the prescriptive engine operates on your premises. In this mode roast telemetry and inference do not leave your network. Optional cloud features (history backup, multi-site sharing) transmit only the data required for that feature, and only when you turn them on.

Sharing

We share data only with service providers who help us operate (e.g. hosting, payments), under contracts that limit their use, or where required by law. We never sell personal or roast data.

Your rights

Depending on your region, you may have rights to access, correct, export, or delete your data. You can export your roast history at any time and request account deletion. We honor verified requests within the timeframes required by applicable law.
