Privacy Policy
Last updated June 2026.
We keep data collection to a minimum. This policy explains what we store and why.
What we collect
- Account: when you sign in with Google we store your email, name, and a Google identifier - only to identify your account.
- Billing: Pro subscriptions are processed by Stripe. We store a Stripe customer id and subscription status. We never see or store your card details.
- Your handwriting strokes stay on your device - tracing is scored locally in your browser and is not uploaded.
What we don't do
We don't sell your data, and we don't show third-party advertising trackers.
