Privacy Policy

Scale Lock collects as little as it can. Your playing never leaves your device, your settings stay in your browser, and payments are handled entirely by Paddle. This page explains what is collected and why. Scale Lock is run by Nik Stefanovski, an individual based in Ontario, Canada.

01What I collect

• Your email address, so you can sign in and so I can contact you about your account.
• Your plan: whether you're on the trial or a paid plan, when it ends, and the customer and subscription references Paddle gives me, so the app knows whether to unlock.
• Basic technical logs kept by my hosting providers, such as IP address, browser type and request times. They're used to keep the service running and secure.

02What I don't collect

• Your playing. The notes you play travel only between your keyboard and your device. They are never sent to a server.
• Your card details. Payments are taken by Paddle. I never see or store your card number.
• Tracking. Scale Lock has no ads, no analytics and no tracking cookies.

03What's stored on your device

The app saves your settings and harmony tables, your sign-in session, and a record of your plan in your browser's local storage. These stay on your device, which is what lets the app keep working if the connection drops. Clearing your browser's data removes them.

04Who helps run Scale Lock

• Supabase stores your account and plan, and sends sign-in emails. Its servers are in the United States.
• Cloudflare hosts the website.
• Paddle processes payments as the merchant of record. Paddle's own privacy policy covers the payment and billing details you give it at checkout.
• Google Fonts supplies the typefaces, so your browser contacts Google's servers, which see your IP address.

These providers process data only to provide their service. Your information may be stored or processed outside Canada, including in the United States, where it is subject to local law.

05How long it's kept

Your account information is kept for as long as you have an account. If you ask me to delete it, I'll do so within 30 days. Paddle keeps records of your purchases for as long as tax law requires.

06Your rights

You can ask to see the information I hold about you, correct it, or delete it, by emailing support@scalelock.app. If you're in the EU or UK, you also have rights under the GDPR, including the right to object and to move your data. If you're not satisfied with my response, you can complain to the Office of the Privacy Commissioner of Canada or your local data protection authority.

07Children

Scale Lock isn't intended for children under 13, and I don't knowingly collect their information.

08Changes

If Scale Lock starts collecting something new, for example syncing your settings to your account, I'll update this page first and let you know about important changes by email or in the app.
