Privacy policy

Sideline Studio is made by Spaikz LLC. Last updated October 7, 2026.

Your photos and player details stay on your device

• Finding your player, cutting them out and drawing posters and videos all happen on your phone or computer. The photos you pick, the posters you make and the player details you enter (name, number, age group, club) are not sent to us or to anyone else.
• Player details, your last settings and styles are saved on your device so they're there next time. Deleting the app, or clearing the website's data in your browser, deletes them.
• Sideline Studio never posts anything for you. When you share, your phone's share sheet sends the files where you choose (Instagram, TikTok, Messages and so on), under that service's own privacy policy.

Your account

You sign in with Apple or Google. Sign-in runs on Google Firebase Authentication, which stores a user ID for you, your email address, and the name and profile picture link your Apple or Google account shares. With Sign in with Apple you can hide your email, and Apple gives us a private relay address instead. We use these only to sign you in and to connect your subscription to you on every device. See Firebase's privacy information.

Subscriptions and payments

• In the iPhone and Android apps, you subscribe through the App Store or Google Play. Apple or Google takes the payment; we never see your card details.
• On the web, checkout is run by RevenueCat with Stripe as the payment processor. Stripe receives your payment details and billing information; we never see your card number. See Stripe's privacy policy.
• We use RevenueCat, Inc. to keep track of who subscribes, across all three. RevenueCat receives your Sideline Studio user ID, your email address, your purchase history from the stores, and basic device information such as the app version and country. See RevenueCat's privacy policy.

What the app downloads

To work, the app loads files from a few public services, which receive your device's IP address and normal web request information, like any website: the app itself from Google Firebase Hosting; fonts from Google Fonts; the sign-in software from Google; the on-device AI models from Hugging Face (once, then they're kept on your device); and the AI runtime and web checkout software from jsDelivr. Nothing about you or your photos is sent with these downloads.

What we don't do

• No ads and no advertising or analytics trackers.
• We don't sell your personal information or share it for advertising.
• We don't use your photos to train AI, because we never receive them.

How long we keep it, and deleting your account

Your account stays until you delete it. In the app, open the account menu (the person icon) and tap Delete account; your sign-in account is deleted right away. Deleting your account doesn't cancel a subscription made through the App Store or Google Play, so cancel it there too. Purchase records may be kept by Apple, Google, Stripe and RevenueCat as needed for tax and accounting. To have your purchase history removed from RevenueCat as well, or if you can't sign in, email support@spaikz.com from the address you signed in with. More on the Support page.

Children

Sideline Studio is meant for parents, guardians, coaches and players aged 13 and over. It isn't directed at children under 13, and we don't knowingly collect personal information from them. Photos of young players that you edit stay on your device. Please only share photos of other people's children with their family's permission.

Your rights

Wherever you live, you can ask us what personal information we hold about you, ask us to correct it or delete it, by emailing support@spaikz.com. We'll answer within 30 days.

Changes

If this policy changes, we'll update it here and change the date at the top. If a change is significant, we'll tell you in the app.
