Privacy

Account data. When you join the waitlist or create an account, we collect your email address and — if you provide them — a small number of survey answers about your training. We use these to decide who to invite into the beta and to shape the product.

Uploaded files. When you upload a fitness export (for example, a Concept2 CSV or a Garmin FIT file), we parse it inside your private workspace to build your Baseline Report. The raw file stays in your workspace; we do not share it with third parties, we do not sell it, and we do not use it to train public AI models.

Usage data. Standard product logs (which pages you visited, error traces, aggregate performance) via Vercel and Sentry.

The AI layer of Baseline (a large-language-model provider, chosen at deploy time by environment variable) is used to generate the natural-language explanations in your report.

We do not send raw uploaded files to the AI layer. Only structured, aggregated summaries — the same ones we show you — are sent. That means no full workout traces, no raw heart-rate streams and no personally-identifying free text.

Baseline runs on Vercel and Supabase. Both are configured to keep your data in the EU region where possible. Some supporting services (for example, the AI provider and email delivery) may process data outside the EU under standard contractual clauses.

You can delete your uploaded files at any time. You can request account deletion — including all associated uploads and reports — by emailing us. We honour UK GDPR data-subject requests (access, correction, deletion, portability) within the required timeframes.

Baseline uses only the cookies needed to keep you signed in and to remember your consent preferences. We do not use third-party advertising cookies.

If we change this policy in a way that materially affects you, we’ll email active users and update the date below.
