This website

If you subscribe, we store the email address you typed. With Resend configured, the address is added to a Resend segment as unsubscribed, and a confirmation email is sent from the configured sender. Opening the link marks the contact subscribed. Until then, broadcasts do not include you. If Resend is not configured, the address is logged and, when the disk allows it, written to a local file. It is not sold.

The site uses Vercel Web Analytics. That records page views and two events: a click on a trial link, and a newsletter signup. There is no ad network and no third-party marketing pixel in this build.

The coach

The Telegram bot is a separate process. It stores your Telegram id, the level, song, minutes, practice time, and timezone you set, the messages you send, recordings you upload, the measurements taken from those recordings, and a subscription status. Recordings are kept so the weekly note can attach them. The language model used to word a plan or a reply receives text, including those measurements. It does not receive the audio.

Payments

This build does not charge a card. When Stripe is connected later, Stripe will process the payment. The bot would store a subscription status, not a card number.

How long, and how to ask

Write to hello@pianonudge.com to ask what is stored for your email or your Telegram id, or to ask for it to be deleted. The draft does not promise a specific retention period. Recordings live on the bot's disk until they are removed.
