By using Product Gym you agree to use it lawfully and to receive sign-in emails containing magic links. We do not send marketing emails; daily reminders happen only through channels you choose, such as calendar invites or optional browser push notifications.
Your account, sessions, and rep history are stored on our infrastructure (Cloudflare D1, KV). You may export or delete your account at any time from your training log.
We use PostHog product analytics to understand app usage and improve the experience. Analytics events may include page views, quiz starts, answer submits, shares, and similar product interactions.
The content shown each day is summarized from third-party sources (Lenny Rachitsky's archive). Original sources retain their rights; quotations and summaries are provided for educational use under fair use.
