What We Collect
yourline may collect account information such as your email address, training progress, saved settings, selected lessons, a compact set of activation milestones, and basic traffic or reliability data. This helps the product work, sync progress, debug issues, and improve training quality without storing a row for every click.
Sessions and Service Providers
Necessary session cookies keep you signed in through Supabase. Vercel hosts the website and may provide aggregate traffic and reliability analytics. Google is involved only when you choose Google sign-in. Lichess receives requests when you connect an account or import public game data. We do not use advertising cookies.
Product Emails
Product-update emails are optional. Your choice and the consent-text version are stored with your account, and you can withdraw consent from Settings at any time. Authentication and essential account emails are separate from product marketing.
Browser-Stored Data
Some data is stored locally in your browser, including settings, recent training sets, engine cache data, and optional Maia-2 model assets if you choose to install Maia. Browser-stored Maia files are used locally for predictions and are not a paid purchase.
How We Use Data
We use data to provide chess training features, save your progress, run analysis and review flows, prevent abuse, improve reliability, and understand which parts of the product need work.
Payments
yourline does not currently sell subscriptions or paid plans, so we do not collect payment card details through the product.
Export and Deletion
Signed-in users can export synced cloud data or permanently delete their account from Settings. You can also request help at support@yourline.app. Account deletion removes the authentication account and cloud records linked to it. Data stored only in your browser can be cleared from the Yourline Data settings or your browser settings.
Policy Updates
We may update this Privacy Policy as yourline changes. Continued use of the product after an update means you accept the updated policy.
