Privacy Policy

Last updated: October 6, 2026

This policy explains what PowerBand ("we", "us") collects and does with information when you use the PowerBand website at powerband.fit, the PowerBand iPhone app, and the PowerBand sensor. The short version: your swings stay on your devices, we have no accounts, and we do not sell your data.

1. The PowerBand app and sensor

• What the sensor measures. Swing speed, ball speed, spin, racquet or club path, face angle, contact point, tempo, punch force and shot counts.
• Where it is stored. Your sessions are stored on your phone, and the sensor keeps about two days of sessions until they sync. We do not upload your sessions to our servers, and we do not require an account.
• Bluetooth. The app asks for Bluetooth permission only to find and connect to your PowerBand sensor. We do not use Bluetooth to track your location or to scan for anything other than PowerBand sensors.
• No tracking. The app has no advertising, no analytics and no third-party tracking tools.
• Your controls. You can export every shot as a CSV file or delete a session, or all of your data, from inside the app. Deleting the app also deletes its data from your phone.

2. Orders and payments

Pre-orders are paid on a secure page run by Stripe. Your card number is entered directly with Stripe and never reaches our website or servers. Stripe shares with us the details we need to fulfil your order: your name, email address, shipping address, the items you chose (including band color) and the payment status. We use that information to process and deliver your order, to email you about it, and to handle returns and support. Stripe's own use of your information is described in Stripe's privacy policy.

3. The website

• The website does not use cookies, advertising or analytics tools.
• It is delivered through hosting and network providers (GitHub Pages and Cloudflare). Like any website, these providers may process your IP address and standard request information to deliver the page and protect it from abuse.
• To display the page, your browser loads fonts from Google Fonts and a 3D library from jsDelivr. These providers receive your IP address and browser information when they serve those files.
• If you enter your email in the checkout window, it is used only to pre-fill your payment page and to contact you about your order.

4. What we do not do

We do not sell your personal information. We do not share it for advertising. We do not build advertising profiles. We share information only with the service providers described above, and with others only when the law requires it.

5. How long we keep information

Information on your own devices stays there until you delete it. Order records are kept as long as needed to fulfil the order, handle returns and meet tax and accounting rules.

6. Your rights

Depending on where you live, you may have the right to ask what information we hold about you, to correct it, to delete it, or to object to how it is used. Because your sessions live on your own devices, you already control them. For anything we hold about an order, contact us at the address below and we will respond within a reasonable time.

7. Children

PowerBand is not directed to children under 13, and we do not knowingly collect personal information from them. If a parent or guardian believes a child has given us personal information, please contact us and we will delete it.

8. Security

We keep your data on your device, use encrypted connections for purchases, and rely on Stripe for card handling. No system is perfectly secure, so we cannot guarantee absolute security.

9. Changes

We may update this policy as the product changes. The date at the top shows when it was last revised, and we will make material changes clear in the app or on this page.
