Who looks after your data

YGS Practice is a project of Erich Andreas (Your Guitar Sage) and Matheus Mello, who builds and runs the app through Doozle, a brand of Quantivo AI, LLC (United States). Together they decide how the data described here is used. For any request about your data, email matheus@doozle.io.

What we collect

• On the waitlist: your name, email and time zone (the form reads it from your browser). You sign up in Your Guitar Sage's form, run on Kajabi, which adds you to Your Guitar Sage's email list with a YGS Practice tag.
• On the founding member plan: you pay on Your Guitar Sage's checkout page, run on Kajabi. We receive your name, email, the amount and the payment confirmation. Your card details stay with the payment provider.

What we use it for

• Telling you about the launch and sending important YGS Practice news.
• Asking you by email what we should build first.
• Delivering the founding member plan, support and refunds.
• Counting which posts, videos and emails bring people, as numbers only, without identifying anyone.

Legal bases

• News and updates: your consent, which you can withdraw at any time.
• Founding member plan: the contract you enter into when you buy, and our legal and tax obligations.

Who we share it with

We don't sell your data or use it for third-party advertising. These providers process it only to provide their service to us:

• Vercel: website hosting.
• Kajabi: the waitlist form, the email list and the founding member checkout.
• Google reCAPTCHA: checks that waitlist signups come from people, not bots. Google's Privacy Policy and Terms apply.
• Google Fonts: the site's fonts, which your browser downloads from Google's servers.

Some of these providers process data outside your country, for example in the United States, under contractual safeguards.

How long we keep it

You stay on the email list until you unsubscribe (every email has a link) or ask us to remove you. Purchase records are kept for as long as the law requires.

Your rights

You can ask to see, correct or delete your data, withdraw your consent, object to its use or get a copy, at any time, by emailing matheus@doozle.io. We answer within 30 days. If you live in California or another U.S. state with a privacy law, you have these rights too. We don't sell or share personal information.

Children

The waitlist and the founding member plan are for adults. If you're under 18, ask a parent or guardian to sign up for you.

Cookies

We don't use advertising or tracking cookies. The site only keeps the tag of the link you came from in your browser tab's memory (sessionStorage), which is cleared when you close the tab. The waitlist form's reCAPTCHA may set a Google cookie it needs to tell people from bots.
